Thus, the surrounding interference objects can be prevented from affecting the clamping of the target object.

Description

Clamping jaw device

Technical Field

The present invention relates to a clamping jaw device, and more particularly, to a clamping jaw device capable of self-adaptation.

Background

The conventional clamping jaw device, as shown in fig. 1A, mainly comprises a base body A1 and two clamping assemblies A2. Each clamping assembly A2 comprises a support frame a21 of the base body A1, a spring a22 arranged in the support frame a21, and a grabbing part a23 connected with the support frame a21 through the spring a 22. The two clamping assemblies A2 can be close to or far away from each other through the moving mechanism of the seat body A1. When the clamping jaw device clamps an object G, the clamping jaw device moves downwards along the Y axis to be close to the object G, after the object G enters a space between the two grabbing parts A23, the two clamping assemblies A2 move close to each other along the X axis until the two grabbing parts A23 clamp the object G, and finally the clamping jaw device moves upwards along the Y axis to complete the clamping task. However, when the clamping jaw device is to clamp a target object from a large group of objects G, the gripping portion a23 is easily retracted upwards due to the collision with the target object or other objects G before clamping the target object, so that the task of clamping the target object cannot be continuously completed.

Another conventional jaw apparatus, as shown in fig. 1B, is mainly composed of a base B1 and two clamping assemblies B2. Each clamping assembly B2 comprises a base body B1, a first support frame B21 and a second support frame B22 which can pivot relative to the base body B1, and a grabbing portion B23 which is connected with the first support frame B21 and the second support frame B22 and can respectively deflect relative to the first support frame B21 and the second support frame B22. The first support B21 and the second support B22 are each provided with a plurality of joints. Similarly, when the clamping jaw device is to clamp a target object from a large group of objects, the grabbing portion B23 is easy to retract due to abutting against the target object or other objects before clamping the target object, so that the task of clamping the target object cannot be continuously completed.

Thus, there is still room for improvement in existing jaw arrangements.

Disclosure of Invention

It is therefore a primary object of the present invention to provide a jaw apparatus that is adaptable to the environment in which the object to be retrieved is located.

According to one embodiment, a jaw apparatus includes a base and two clamping assemblies. Each clamping assembly comprises a clamping piece bracket and an elastic piece. The clamping piece comprises a clamping part and a clamping supporting part, and the clamping supporting part comprises a first pivoting part. The support is movably arranged on the seat body. The bracket comprises a connecting part and a bracket supporting part, and the bracket supporting part comprises a second pivoting part. The first pivoting part is pivoted with the second pivoting part, and the pivoting part of the first pivoting part and the second pivoting part is positioned between the clamping part and the connecting part, so that the clamping piece can pivot relative to the bracket. The elastic member includes a first end and a second end opposite the first end. The first end of the elastic piece is used for being connected with the clamping supporting portion, and the second end of the elastic piece is used for being connected with the connecting portion. When the clamping part of the clamping piece of one clamping component is abutted against an object and the two clamping components are not abutted against each other, the clamping piece pivots relative to the corresponding bracket; when the clamping part of the clamping piece of one clamping assembly is abutted against the object and the clamping supporting parts of the two clamping assemblies are abutted against each other, the clamping pieces are limited to pivot so as to clamp the object.

Therefore, the clamping jaw device provided by the invention can be self-adaptive to the environment of the target object to be taken, and can continuously complete the clamping task by eliminating the influence of interference objects.

Detailed Description

The following description of the present invention will be made clearly and fully, and it is apparent that the embodiments described are some, but not all, of the embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 2 and 4B, a clamping jaw device according to an embodiment of the invention is suitable for clamping an object, and is particularly suitable for clamping one of a group of objects G. The present invention is not limited to the type of the object G, but for convenience of description, the following embodiments will be described by taking the object G as a steel ball as an example.

As shown, the jaw apparatus comprises a housing 10 and two clamping assemblies 11. The housing 10 includes a displacement structure 101. The two clamping assemblies 11 are respectively movably arranged on the base body 10. Each clamping assembly 11 includes a clamping member 110, a bracket 120, a pivoting member 130, and an elastic member 140. The respective components will be described in detail as follows.

The clamping member 110 includes a first surface 111, a second surface 112 opposite the first surface 111, a third surface 113 connecting the first surface 111 and the second surface 112, and a fourth surface 114 opposite the third surface 113. The clamping member 110 further includes a clamping portion 110A and a clamping support portion 110B, and the clamping portion 110A extends along the Y-axis from the clamping support portion 110B. The clamping portion 110A contacts the object G when clamping the object G. The clamping support portion 110B is connected to the clamping portion 110A, and includes a first pivot portion CH1. The first pivot portion CH1 may, for example, include a first mounting hole H1, where the first mounting hole H1 penetrates through the first surface 111 and the second surface 112. The third surface 113 is concavely provided with a groove R1, and the groove R1 is used for holding the object G between the two third surfaces 113 of the two clamping members 110 when clamping the object G.

The two brackets 120 are movably disposed on the displacement structure 101, so that when the two brackets 120 are relatively movable on the displacement structure 101 along the X axis, the two clamping assemblies 11 can relatively move on the seat 10 along the X axis. Each bracket 120 includes a connection portion 120A and a bracket support portion 120B. The connection portion 120A is configured to be mounted on the displacement structure 101. The bracket support portion 120B includes a second pivot portion CH2 pivotally connected to the first pivot portion CH1. The second pivot portion CH2 may, for example, include a second mounting hole H2, where a position of the second mounting hole H2 corresponds to a position of the first mounting hole H1. Thus, when assembling the jaw apparatus, the pivoting member 130 may be inserted into the first and second mounting holes H1 and H2 such that the clamping member 110 may pivot with respect to the bracket 120. The pivot point of the first pivot portion CH1 and the second pivot portion CH2 is located between the clamping portion 111 and the connecting portion 120A, that is, the pivot member 130 is located between the clamping portion 111 and the connecting portion 120A.

The elastic member 140 may be, for example, a spring. The elastic member 140 includes a first end 141 and a second end 142 opposite the first end 141. The first end 141 of the elastic member 140 is configured to connect to the clamping support portion 110B, and the second end 142 of the elastic member 140 is configured to connect to the connecting portion 120A, such that the elastic member 140 is located between the clamping support portion 110B and the connecting portion 120A. In detail, the clamping assembly 11 further includes a connecting member 15 and two locking members 16. The connecting piece 15 is configured on the clamping support portion 110B, for example, assembled on the clamping support portion 110B by using a locking piece, or formed on the clamping support portion 110B in an integrally formed manner. The connecting member 15 includes a third mounting hole H3. One of the locking members 16 may be inserted into the third mounting hole H3, so that the first end 141 of the elastic member 140 may be connected to the clamping support portion 110B through the locking member 16, for example, the first end 141 of the elastic member 140 is hung on the locking member 16. The connection portion 120A of the bracket 120 further includes a fourth mounting hole H4. The other locking member 16 can be inserted into the fourth mounting hole H4, so that the second end 142 of the elastic member 140 can be connected to the connecting portion 120A through the locking member 16, for example, the second end 142 of the elastic member 140 is hung on the locking member 16.

In this embodiment or other embodiments, the at least one clamping assembly 11 further includes an adjusting member 17 and an adjusting mechanism 115 at the clamping support 110B. The adjusting member 17 is configured to be mounted on the adjusting mechanism 115. The first mounting hole H1 is located between the adjustment mechanism 115 and the clamping portion 110A, that is, the rotation center of the clamping member 110 is located between the adjustment mechanism 115 and the clamping portion 110A. The adjustment mechanism 115 includes a plurality of adjustment positions. These adjustment positions may be arranged along the X-axis. Therefore, the clamping support portion 110B of one clamping member 110 can abut against the adjusting member 17 provided on the other clamping member 110. The position of the adjusting member 17 at the different adjustment positions determines the size of the space between the two clamping portions 110A, or the size of the space between the two recesses R1.

In fig. 2, the adjusting mechanism 115 is a plurality of insertion holes, and these insertion holes respectively correspond to the above-described adjusting positions. However, the present invention is not limited thereto, and in other embodiments, the adjusting mechanism may be, for example, a chute, and the adjusting positions are respectively disposed on the chute; alternatively, the adjusting mechanism may be, for example, a long groove with a tooth row at an edge, and the adjusting positions are respectively disposed on the long groove. Different types of adjustment mechanisms may be associated with the appropriate type of adjustment member 17.

In this embodiment or other embodiments, the clamping support portion 110B of each clamping member 110 further includes a protruding structure 116 protruding from the third surface 113. The protruding structure 116 may, for example, be protruding from the third surface 113 along the X-axis. Since the two third surfaces 113 of the two clamping members 110 are opposite to each other, the two protruding structures 116 are also opposite to each other. The portion of the third surface 113 located on the protruding structure 116 may be, for example, a plane or an arc.

The clamping device is first moved along the Y-axis during the process of clamping the object G. If the third surface 113 of the clamping portion 110A abuts against the object G (target object), as shown in fig. 4A, the clamping portion 110 slightly deflects along the direction D1. The clamping device can then be moved further along the Y-axis until the object G enters the recess R1. And, the two clamping members 110 are brought close to each other along the X-axis until the clamping support portion 110B of one clamping member 110 contacts the regulating member 17 on the other clamping member 110, as shown in fig. 2. While the two clamping members 110 are approaching each other, the clamping members 110 slightly deflect along the direction D2 in fig. 4B until a force balance is achieved between the tensile force on the elastic members 140 connecting the bracket 120 and the clamping support portion 110B and the abutting force of the object G against the clamping portion 110A. At this time, the two clamping portions 110A clamp the object G, so that the object G is held on the central axis P of the clamping device. Then, the clamping device can move along the Y axis in the opposite direction to finish the clamping task.

In another case, if the fourth surface 114 of the clamping portion 110A abuts against the object G (the interfering object), as shown in fig. 4B, the clamping member 110 slightly deflects along the direction D2 until the tension on the elastic member 140 connecting the bracket 120 and the clamping support portion 110B and the abutting force of the object G against the clamping portion 110A reach a force balance. Under the condition that the force balance is achieved, the clamping device can continue to downwards move along the Y axis, so that the target object enters between the two clamping parts 110A, and the two clamping parts 110 approach each other along the X axis to clamp the target object.

The above embodiment is described with respect to the two clamping members 110 having the non-intersecting shape for clamping the object G as an example of the clamping device, but the invention is not limited thereto. In other embodiments of the present invention, the two clamping members may also take the form of a cross to clamp the object G.

Referring to fig. 5, 6 and 7A to 7D, two clamping assemblies 21 of the clamping device include a clamping member 210, a bracket 120, a pivot member 130 and an elastic member 140. The bracket 120, the pivot member 130 and the elastic member 140 are the same as the bracket 120, the pivot member 130 and the elastic member 140 in the embodiment of fig. 2, so the manner of assembling the clamping member 210 to the bracket 120 and the manner of assembling the elastic member 140 to the bracket 120 and the clamping member 210 by using the pivot member 130 will be referred to the above related description, and will not be repeated herein.

Each clip 210 includes a first surface 211, a second surface 212 opposite the first surface 211, a third surface 213 connecting the first surface 211 and the second surface 212, and a fourth surface 214 opposite the third surface 213. The clamping member 210 further includes a clamping portion 210A and a clamping support portion 210B, and the clamping portion 210A extends along the Y-axis from the clamping support portion 210B. The clamping portion 210A contacts the object G when clamping the object G. The clamping support portion 210B includes a first pivot portion CH1. The first pivot portion CH1 may, for example, include a first mounting hole H1, where the first mounting hole H1 penetrates the first surface 211 and the second surface 212. A portion of the fourth surface 214 of the clamping portion 210A is recessed with a groove R2.

Each clamp 210A includes a first section 217, a turn section 218, and a second section 219, the turn section 218 being located between the first section 217 and the second section 219. The first section 217 is inclined toward the central axis of the jaw apparatus and the second section 219 extends along the Y-axis in a direction away from the clamp support 120B. Thus, each clamping portion 210A forms a recess, and the openings of the two recesses are opposite to each other. When the two clamping members 210 are close to each other to clamp the object G, the two clamping portions 210A of the two clamping members 210 intersect, and the two grooves R2 of the two clamping portions 210A are opposite to each other.

On the other hand, in the present embodiment or other embodiments, the at least one clamping assembly 21 further includes an adjusting member 17, and the clamping support portion 210B of the clamping member 210 further includes an adjusting mechanism 115. The adjusting member 17 and the adjusting mechanism 115 of fig. 5 are identical or similar to the adjusting member 17 and the adjusting mechanism 115 of fig. 2, and thus reference is made to the above-mentioned related description, and the detailed description thereof is omitted.

In this embodiment or other embodiments, the clamping support portion 210B of each clamping member 210 further includes a protruding structure 216 protruding from the third surface 213. The protruding structure 216 may, for example, be protruding from the third surface 213 along the X-axis. Since the two third surfaces 213 of the two clamping members 210 are opposite to each other, the two protruding structures 216 are also opposite to each other. The portion of the third surface 213 located on the protruding structure 216 may be, for example, a planar surface or an arcuate surface.

In this embodiment or other embodiments, at least one of the clamping support portions 210B further includes a stopping member BR, where the stopping member BR is protruding from the first surface 211 or the second surface 212 of the clamping support portion 210B, and the stopping member BR is used for being abutted by the adjusting member 17 mounted on the opposite clamping support portion 210B.

In the process of gripping the object G, the gripping device moves along the Y-axis to make the gripping portion 210A of the gripping member 210 approach the object G, as shown in fig. 7A. When one of the clamping portions 210A abuts against the object G, as shown in fig. 7B, the clamping member 210 abutting against the object G slightly swings along the direction D3, and the space between the two clamping portions 210A is enlarged. The clamping device continues to move downward along the Y-axis, so that the object G enters between the two grooves R2 of the two clamping portions 210A, as shown in fig. 7B. After the object G enters between the two grooves R2, the two clamping members 210 can be separated from each other along the X-axis until the stop member BR on one clamping member 210 contacts the adjusting member 17 on the other clamping member 210, as shown in fig. 7C. While the two clamping members 210 are away from each other, the clamping members 210 slightly swing along the direction D4 until the tension on the elastic members 140 connecting the bracket 120 and the clamping support portion 210B and the object G are in contact with each other to achieve a force balance between the contact forces of the clamping portion 210A. At this time, the two clamping portions 210A clamp the object G, so that the object G is held on the central axis P of the clamping device, as shown in fig. 7D. Then, the clamping device can move along the Y axis in the opposite direction to finish the clamping task.

In the above embodiments, the elastic member 140 is connected to the second surface 112 (212) of the clamping support portion 110B (210B) and the connecting portion 120A of the bracket 120 by the connecting member 15, but the invention is not limited thereto.

In other embodiments of the present invention, as shown in fig. 8, in each clamping assembly 31, the clamping member 310 may be, for example, the clamping member 110 of fig. 2 or the clamping member 220 of fig. 5, the clamping member 310 including a first surface 311, a second surface 312 opposite to the first surface 311, a third surface 313 connecting the first surface 311 and the second surface 312, and a fourth surface 314 opposite to the third surface 313. The clamping support portion 310B of the clamping member 310 further includes an extension portion 330. The extension 330 may, for example, extend from the fourth surface 314 of the clamp 310. The first end 341 of the elastic member 340 of the clamping assembly 31 can be connected to the extension portion 330 of the clamping support portion 310B, and the second end 342 of the elastic member 340 can be connected to the connecting portion 320A of the bracket 320.

In the above embodiments, the clamping members and the brackets of one clamping assembly are symmetrically arranged with the clamping members and brackets of the other clamping assembly, for example, the symmetrical arrangement in fig. 2 means that two second surfaces 112 of the two clamping members 110 of the two clamping assemblies 11 far away from and opposite to the bracket supporting portion 120B of the corresponding bracket 120 are respectively facing opposite sides of the clamping device; however, the present invention is not limited thereto. In other embodiments of the present invention, the clamping members and brackets of one clamping assembly and the clamping members and brackets of the other clamping assembly may be mirror images.

Referring to fig. 9, the clamping device includes two clamping assemblies 41, and each clamping assembly 41 includes a clamping member 410, a bracket 420, a pivot member 430 and an elastic member 440. The two clamping members 410 of the two sets of clamping assemblies 41 are facing away from and opposite to the same side of the clamping device as the two surfaces 412 of the bracket support 420B of the corresponding bracket 420. The adjustment mechanism and the adjustment member may be omitted from the clamp support portion 410B of the clamp 410. The remaining arrangements of the clamping member 410, the bracket 420, the pivot member 430 and the elastic member 440 in fig. 9 can refer to the arrangements of the clamping member 110, the bracket 120, the pivot member 130 and the elastic member 140 in fig. 2, or refer to the arrangements of the clamping member 210, the bracket 220, the pivot member 230 and the elastic member 240 in fig. 5, or refer to the arrangements of the clamping member 310, the bracket 320, the pivot member 330 and the elastic member 340 in fig. 8, which will not be repeated herein.

When the end of the clamping portion 410A of one of the clamping members 410 abuts against the object during the clamping process, the clamping device can make the two clamping assemblies 41 approach each other along the X-axis, and keep the minimum distance between the two clamping support portions 410B at a specific value. At this time, the clamping device can be further moved along the Y-axis, so that the object enters between the two clamping portions 410A. During the process of the object entering between the two clamping portions 410A, the clamping member 410 slightly swings relative to the bracket 420, and the swing amplitude is limited by the minimum distance between the two clamping support portions 410B, that is, when at least one of the clamping members 410B is in contact due to the swing of the clamping member 410, the clamping member 410 cannot continuously deflect in the same direction. At this time, the two clamping members 41 can be kept close to each other or kept still along the X-axis until the force balance is achieved between the tensile force on the elastic member 440 and the abutting force on the clamping portion 410A, and the two clamping portions 410A can clamp the object, so that the object is kept on the central axis of the clamping device. Then, the clamping device can move along the Y axis in the opposite direction to finish the clamping task.

In order to enable the clamping space between the two clamping parts of the two clamping assemblies arranged in a mirror image mode to have adjustable elasticity so as to adapt to objects to be taken in different sizes, an adjusting mechanism and an adjusting piece can be further arranged on the clamping supporting part of at least one clamping assembly. For example, referring to fig. 10, the clamping device includes two clamping assemblies 51, and at least one clamping support portion 510B of the clamping assemblies 51 further includes an adjusting mechanism and an adjusting member 57. In detail, the adjusting mechanism includes a sliding slot S1 disposed on the surface 512 of the clamping member 510 away from the bracket 520, and a sliding block 58 disposed in the sliding slot H1 and having a sliding slot S2. The two runners S1 and S2 may extend along the X-axis. The sliding slot S1 may be concavely provided with a recess (not shown), into which the adjusting member 57 may be inserted. The slide 58 is movable along the slide S1 in the X-axis to different adjustment positions relative to the clamping member 510, so that the adjustment member 57 can be moved along the slide S2 simultaneously to corresponding different adjustment positions relative to the slide 58. Therefore, the degree to which the slider 58 protrudes from the clamping support portion 510B of the clamping member 510, that is, the degree to which the surface 581 of the opposite clamping member 510 on the slider 58 protrudes from the clamping support portion 510B, can be selectively adjusted, so as to adjust the size of the maximum clamping space between the two clamping portions 510A of the two clamping members 510.

Alternatively, the adjustment mechanism may include a recess S3 provided on the surface 612 of the holder 610 remote from the bracket 620, a slider 68 having a slide groove S4, and a row of teeth 69 provided in the recess S3, as shown in FIG. 11, for example. The row of teeth 69 may be, for example, a resilient pad, and has a tooth surface 691 and a recess (not shown) concavely provided on the tooth surface 691. The two grooves S3 and S4 may extend along the X-axis. The adjusting member 67 may be inserted into the sliding slot S4 of the slider 68, and then inserted into the concave hole on the tooth row member 69, so as to movably mount the slider 68 on the tooth row member 69. The surface of slider 68 facing row of teeth 69 may be toothed surface 682, and the texture of toothed surface 682 engages toothed surface 691 of row of teeth 69. The slide 68 is movable along the X-axis to different adjustment positions relative to the clamp 610, so that the adjustment member 67 can be moved along the slide S4 to corresponding different adjustment positions relative to the slide 68 at the same time. Therefore, the degree to which the slider 68 protrudes from the clamping support portion 610B of the clamping member 610, that is, the degree to which the surface 681 of the slider 68 facing the opposite clamping member 610 protrudes from the clamping support portion 610B thereof, can be selectively adjusted, so as to adjust the size of the maximum clamping space between the two clamping portions 610A of the two clamping members 610.

Although the above embodiment is described by using the example that the pivoting member is inserted into the bracket supporting portion of the bracket and the clamping supporting portion of the clamping member, the present invention is not limited to this example. In other embodiments of the present invention, other pivoting means may be used to pivot the support portion of the bracket to the clamping support portion of the clamping member, so that the clamping member can pivot relative to the bracket.
