Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gilt vise for holding a work, and more particularly, to a giant vise having a toggle press mechanism and capable of easily holding and releasing the work by rotating an operation lever. About.

[0002]

2. Description of the Related Art A conventional vise is a fixed member having a guide rod and a holding piece bent from the guide rod.
And a movable member through which the guide rod portion is slidably inserted. A fixed-side jaw that is in contact with one surface of the work is disposed at the tip of the holding piece of the fixed-side member. A screw rod is screwed into the distal end of the movable member so as to be along the guide rod portion. The movable jaw contacts the distal end of the screw rod, faces the fixed side jaw, and contacts the other surface of the workpiece. Department was arranged.

When using the giant vise, first, the movable member is moved with respect to the guide rod so that the distance between the fixed jaw and the movable jaw is substantially equal to the thickness of the work to be clamped. The fixed side jaw and the movable side jaw are arranged on both sides of the work so as to coincide with each other.

Thereafter, by turning the screw rod to bring the movable side jaw closer to the fixed side jaw, the work can be held between the fixed side jaw and the movable side jaw.

When the movable member clamps the work by rotating the screw rod, the periphery of the insertion hole into which the guide rod is inserted is formed in a form like a cascade on the peripheral surface of the guide rod. The work can be held between the fixed jaw and the movable jaw without slipping.

[0006]

However, in the conventional vice vise, it is necessary to hold the fixed side members such as the guide rod and rotate the screw rod when clamping the work.
This operation of turning the screw rod requires a force, so that the screw rod is turned by applying a wrench or the like to the screw rod, and it becomes necessary to grip the wrench or the like. When using a tool such as a wrench, it is necessary to arrange the tool in a direction perpendicular to the screw rod and to operate it so as not to interfere with the guide rod, etc. It becomes an operation.

In order to release the workpiece from being strongly clamped after the workpiece is clamped, it is necessary to apply a tool such as a wrench to the threaded rod, hit the tool with a hammer or the like, and turn the threaded rod together with the tool. As a result, it is necessary to hold the tool and the hammer and the like, and furthermore, the operation is troublesome.

Further, since the screw rod is turned when the work is clamped, even if the movable jaw is rotatably arranged at the end of the screw rod, when the clamping force of the work is increased, the operation is reversed. It is unavoidable that the movable jaw and the screw rod are unrotatably integrated by force. Therefore, when the screw rod is turned, the movable side flange also rotates, causing a case where the work is shifted.

The present invention has been made to solve the above-mentioned problems, and can easily perform the operation of clamping and releasing a work.
It is an object of the present invention to provide a giant vise that can prevent the work from shifting when nipped.

[0010]

According to the present invention, a giant vise according to the present invention comprises a guide rod, a holding piece bent from the guide rod,
A fixed side member having a first jaw provided at a tip of the holding piece, and a movable side loosely fitted around the outer periphery of the guide rod and movable along the axial direction of the guide rod. Components,
A movable rod held at a distal end of the movable side member so as to be movable within a predetermined range in an axial direction of the guide rod, wherein a second jaw located opposite to the first jaw has a distal end; A toggle rod mechanism comprising a moving rod provided on the moving member and a first link connected to the moving rod and a second link connected to the movable member. A toggle press that moves the second jaw at the tip of the moving rod toward the first jaw by moving the two link portions inward of the connection point, thereby applying a clamping force between the first and second jaws. A mechanism, an operation lever provided for tilting the first link portion, and a handle provided on the movable member opposite to the operation lever are provided.

In this case, the main body of the operating lever is pivotally supported by the connecting piece of the moving rod as the first link, and the main body of the operating lever is provided. Is connected to the protruding piece of the movable side member via the second link portion, and a spring is provided for urging the operation lever to the open side, and the operation lever is rotated to the open side to An adjusting screw for restricting the rotation angle of the operation lever and the movement width of the moving bar when the moving bar moves to the non-press side may be provided.

According to another aspect of the present invention, the length of the first link portion of the toggle press mechanism can be changed by rotating the operation lever. The stroke length at the time of pinching can be adjusted by rotating the operation lever.

In this case, the operating lever has a screw rod and is rotatable, and the main body is disposed closer to the base than the operating part by inserting the screw rod therein. And the main body is rotatably supported as a shaft of a first link portion of the toggle press mechanism by a connecting piece protruding from the moving rod, and a support member screwes the screw rod into the main body. The support member has a support hole for rotatably supporting an axis of a pivot portion of the first link portion and the second link portion, and the operation portion and the support member are connected to each other. When the operation portion is rotated, the support member is moved along the axial direction of the operation lever in the main body portion to change the length of the first link portion.

[0014]

According to the present invention, when holding a workpiece, for example, holding a giant vise in one hand and moving the movable member to an arbitrary position with respect to the guide rod portion of the fixed member. By sliding, the dimension between the first jaw and the second jaw substantially corresponds to the thickness dimension of the work to be clamped, and the first jaw and the second jaw are applied to both surfaces of the work.

Then, by holding the operating lever and the handle with the other hand and turning the operating lever inward, the connection point of the first link portion and the second link portion of the toggle press mechanism moves inward, As a result, the second jaw at the tip of the moving rod moves toward the first jaw, and the work is held between the first and second jaws by the strong holding force of the toggle press mechanism. At this time,
The connection point of the first link portion and the second link portion of the toggle press mechanism is stable beyond the dead point located on the line connecting the rotation axes of the two links, and the holding state is maintained.

Thus, since the handle is provided opposite to the operation lever, even a handicapped person can easily turn and operate the operation lever with one hand to clamp the work. In addition, the operation of the toggle press mechanism causes the moving rod to move in parallel with the guide rod, and the second jaw to move toward the first jaw, thereby clamping the work. There is no risk of shifting the work without rotating the jaw in the circumferential direction as in the above.

In order to release the clamping, contrary to the clamping, the operation lever is tilted so as to open outward, and the moving rod moves to the opposite clamping piece portion side by the action of the toggle press mechanism. The two jaws move to the opposite side of the first jaw to release the work from being held.

According to a second aspect of the present invention, the main body of the operating lever is pivotally supported as a first link by the connecting piece of the moving rod, and an intermediate portion of the main body of the operating lever is movable via the second link. A spring is provided to bias the operation lever to the open side, and the rotation angle and the rotation angle of the operation lever when the operation rod is rotated to the open side and the moving rod is moved to the opposite side of the press. It is possible to adopt a configuration in which an adjusting screw for limiting the moving width of the moving bar is provided.

In this case, by adjusting the adjusting screw,
It is possible to adjust the rotation angle of the operation lever to the open side and the position that limits the movement width of the moving rod, and thereby the stroke length of the force point of the toggle press mechanism, that is, the stroke length of the second jaw (movement amount) ) Changes, and if the stroke length is increased, the work can be more strongly held,
If the stroke length is shortened, the clamping force of the work can be reduced.

[0020] In the above-described configuration, the main body of the operation lever can be configured as the first link portion, and the adjusting screw can move the movable side member so as to limit the rotation angle of the operation lever and the moving width of the moving rod. Since it only needs to be attached to the or its protruding piece, the structure is simple and the manufacturing cost can be reduced.

[0021]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 to 7 show a giant vise according to the first embodiment. The giant vise is an L-shaped fixed member 1 having a guide rod portion 2 and a holding piece 3 bent from the guide rod portion 2. And a movable side member 6 loosely and slidably fitted on the outer periphery of the guide rod portion 2.

A fixed side jaw 4 as a first jaw is provided at the tip of the holding piece 3 of the fixed side member 1 so as to abut on the lower surface of the work Wb. The fixed side jaw 4 has a work W
A cover made of synthetic resin is attached so as not to damage b.

The movable side member 6 has an insertion hole 6a through which the guide rod 2 can be inserted, corresponding to the cross-sectional shape (irregular cross section) of the guide rod 2. The insertion hole 6a is formed so that the movable-side member 6 is loosely fitted with a gap therebetween. When even a slight tilting force is applied to the movable-side member 6, the fitting portion is easily engaged and locked. It is formed.

The movable rod 5 can be pivoted in a predetermined range substantially in parallel with the guide rod 2 via the first and second pivots 8 and 9 on the distal end side of the movable member 6. Provided. Moving stick 5
A movable side jaw 13 serving as a second jaw is movably disposed in a ball joint type at a tip of the fixed side jaw 4 so as to face the fixed side jaw 4. A cover made of synthetic resin is attached to the movable jaw 13 so as not to damage the work Wa. On the other hand, a handle 7 is provided vertically above the movable member 6 along the guide bar 2.

The movable side member 6 has a fixed side jaw 4 so that the movable bar 5 is slidably held substantially parallel to the guide bar 2.
The first sliding portion 8 is formed with a sliding hole 8a on the side, and the second sliding portion 9 is formed with a sliding hole 9a provided at a position away from the fixed side jaw 4. The moving rod 5 is inserted into the pivot holes 8a, 9a so as to be pivotable.

A protruding piece 10 extending outward in the radial direction of the moving rod 5 is fixed to the second sliding portion 9, and the protruding piece 10 restricts the movement of the moving rod 5 and the opening of the operation lever. An adjusting screw 11 is screwed in, and one end of a link 15 as a second link portion is connected to a distal end side of the protruding piece 10 via a shaft 14. A coil spring 11a is externally fitted to the adjusting screw 11, and two links 15 are used so as to sandwich the projecting piece 10, as shown in FIG.

A connecting piece 12 extending outward in the radial direction of the moving bar 5 is fixed substantially parallel to the projecting piece 10 between the first and second sliding portions 8 and 9 of the moving bar 5. Adjustment screw 11
Usually abuts against the upper surface of the connecting piece 12 to limit the upward movement range of the moving rod 5.

An operating lever 17 is rotatably supported at the tip of the connecting piece 12 via a shaft 16, and the other end of the link 15 is connected to an intermediate portion of the operating lever 17 via a shaft 18. . As shown in FIG. 5, the operation lever 17 is formed three-dimensionally so as to have side walls on both sides of the front plate.
5. The connecting piece 12 is inserted into the operation lever 17 and supported by the shaft.

The operation lever 17 is disposed at a position opposite to the handle 7 so that the operation lever 17 can be easily tilted by being gripped together with the handle. A coil spring 19 for urging the operation lever 17 in a direction to open outward is mounted on the shaft 16. The portion from the shaft 16 to the shaft 18 of the operation lever 17 forms a first link portion, and a toggle press mechanism 20 is formed by the first link portion and the second link portion (link 15).

Therefore, when the operation lever 17 is rotated inward as shown in FIG. 4 from the state shown in FIG. 1 in which the operation lever 17 is opened outward, the shaft 1 serving as an intermediate point of the toggle press mechanism is rotated.
As the point 8 approaches the dead point (point on the straight line L connecting the axis 14 and the axis 16), the force of the axis 16 to descend, that is, the movable rod 5 connected via the connecting piece 12 and the movable side jaw at the tip thereof The pressing force by which the work 13 presses the work Wa (the holding force for holding the work with the fixed-side jaw 4) is increased.

Next, a description will be given of the use mode of the giant vise. First, as shown in FIG.
When holding the fixed side member 1 with one hand, for example, the movable side member 6 is slid with respect to the guide rod portion 2 so that the dimension between the jaws 4 and 13 can be adjusted to hold the workpiece Wa / Wb. The jaws 4 and 13 are brought into contact with both surfaces of the workpieces Wa and Wb, respectively.

Next, the operation lever 17 is gripped together with the handle 7 and the operation lever 17 is moved inward (toward the handle 7 side, fixed side member) so as to be substantially parallel to the moving rod 5 as shown in FIGS. 1).

At this time, the toggle press mechanism 20 having the lower portion of the operation lever 17 as the first link portion acts to push out the shaft 16, ie, the connecting piece 12 and the moving rod 5, which is the point of force, downward, and the pressing force. Is the midpoint of the link (axis 18)
Becomes closer to the dead center on the line L, and is stabilized at a position beyond the dead center. By the action of the toggle press mechanism, the movable rod 5 moves to the fixed jaw 4 side, and the movable jaw 1
3 is pressed against the fixed jaw 4 with a strong force, and the workpiece Wa,
Wb is strongly clamped between the movable jaw 13 and the fixed jaw 4.

As shown in FIG. 2, when the operation lever 17 is operated to clamp the work W, the movable side member 6 has the periphery of the insertion hole 7 into which the guide rod 2 is inserted. Since the peripheral surface has a kazil-like aspect, the work W can be sandwiched between the fixed-side jaw 4 and the movable-side jaw 13 without shifting along the guide rod portion 2.

At the time of pinching, the moving rod 5 moves to approach the fixed side jaw 4 and does not rotate in the circumferential direction. Therefore, the movable side jaw 13 arranged on the tip side of the moving rod 5
Does not rotate, and does not shift the workpieces Wa and Wb at all. When only the operation lever 17 is rotated inward with one hand, the entire giant vise easily moves in that direction and separates from the workpieces Wa and Wb, but the handle 7 is located between the operation lever 17 and the fixed side member 1. Handle 7 and operating lever 1
If the grip 7 is grasped and the operation lever 17 is rotated, the workpieces Wa and Wb can be easily held while the jaws are positioned at predetermined positions of the workpieces Wa and Wb.

In order to release the clamping, the operation lever 17 is pivotally rotated back to return to the outside, and the toggle press mechanism 20 exceeds the dead center in the opposite direction, and the shaft 1
Acts to reduce the distance between the movable jaw 4 and the movable jaw 13, thereby moving the movable bar 5 up and moving the movable jaw 13 away from the fixed jaw 4.
The work W (Wa / Wb) can be released from being pinched.

On the other hand, the pinching force of the vise, that is, the stroke length of the moving rod 5 when the operation lever 17 is operated can be adjusted by the adjusting screw 11. That is,
When the stroke length of the moving rod 5 is reduced to reduce the holding force, as shown in FIG.
The upper limit position when the operating lever 17 is rotated to the open side and the moving rod 5 moves upward to the non-press side is limited. Thereby, the rotation angle at the time of operating the operation lever 17 is limited to a small value, the movement width (downward length) of the moving rod 5 is limited, and the clamping force of the work between the jaws 4 and 13 is reduced.
In order to increase the holding force, on the contrary, the screwing length of the adjusting screw 11 is shortened, and the stroke length of the moving rod 5 is increased.

FIGS. 8 to 11 show a vise vise according to the second embodiment. The giant vise is fixed on its fixed side member 3
1. The guide bar 32, the holding piece 33, and the fixed jaw 34 have the same structure as in the above embodiment, and the movable member 36, the moving bar 35, and the handle 37 have almost the same structure as in the above embodiment.
Regarding the operation lever 47 and the toggle press mechanism 50,
It has a structure different from the above embodiment.

That is, in the toggle press mechanism 50 of the giant vise, the length of the first link portion is
It is configured to be changed by a rotation operation around the axis of. An operation lever 47 is provided with a screw rod 47c protruding at a lower end thereof and an operation unit 47a rotatably provided on a main body 47b,

The lower end of the main body 47b is connected to the connecting piece 42 projecting and fixed in the middle of the moving rod 35 by the toggle press mechanism 5.
The first link portion is pivotally supported via a shaft 46 which is the axis of the first link portion. A support member 41 formed in a U-shape is disposed in the main body portion 47b, and a screw rod 47c is screwed into a screw hole provided at an upper end of the support member 41.

On the other hand, as in the above-described embodiment, a moving rod 35 is provided on the distal end side of the movable side member 36 with the first and second pivoting parts 38,
A guide 39 is provided so as to be able to pivot within a predetermined range substantially in parallel with the guide bar 32. A movable side jaw 43 serving as a second jaw is movably disposed at the lower end of the moving rod 35 so as to face the fixed side jaw 34. A handle 37 is provided vertically above the movable member 36 along the guide bar 32.

The movable side member 36 has a sliding hole provided on the fixed side jaw 34 side so as to slidably hold the moving rod 35 substantially parallel to the guide rod 32. The second sliding portion 39 is formed with a sliding hole at a position away from the fixed side jaw portion 34. The moving rod 35 is inserted into the pivot hole so as to be pivotable. A handle 37 is provided at the upper end of the movable member 36 at a position facing the operation lever 47 along the guide bar 32. In addition, the second sliding portion 39 includes:
A projecting piece 40 extending outward in the radial direction of the moving rod 35 is provided in a projecting manner, and this projecting piece 40 is inserted into the support member 41. A link 45 made of two plates is connected to a tip of the protruding piece 40 via a shaft 44, and a tip of the link 45 is connected to the support member 41 via a shaft 48.

Both ends of the shaft 48 supported by the support member 41 are movably fitted into long holes 47d provided on both sides of the main body 47b of the operation lever 47. With such a configuration, a portion from the shaft 46 to the shaft 48 of the operation lever 47 forms a first link portion, and the first link portion and the second link portion (link 45) form a toggle press mechanism 50. You.

In the toggle press mechanism 50,
By rotating the operation portion 47a of the operation lever 47 around its axis, the support member 41 moves up or down via the screw rod 47c, and the vertical position of the shaft 48 changes. As a result, the distance between the shaft 42 and the shaft 48 of the toggle press mechanism 50 changes, and the length of the first link portion is adjusted by rotating the operation portion 47a around the axis, so that the movable side jaw portion 43 holds the work. The pressing force (a clamping force for clamping the work with the fixed side jaw 34) can be adjusted.

Next, the mode of use of the giant vise will be described. First, the fixed side member 31 is held with one hand, for example.
By sliding the movable side member 36 with respect to the guide rod portion 32,
The work Wa, which clamps the dimension between the jaws 34 and 43,
The workpiece W is set in a state substantially corresponding to the thickness dimension of Wb.
The jaws 34 and 43 are respectively brought into contact with both surfaces of a and Wb. Then, the operation lever 47 is gripped together with the handle 37 so that the operation lever 47 is substantially parallel to the moving rod 35.
Is turned inward (toward the handle 37 and the fixed member 31).

At this time, the main body 47b of the operation lever 47

The shaft 46 serving as the power point, that is, the connecting piece 42 and the moving rod 35
And the pressing force is increased as the intermediate point (axis 48) of the link approaches the dead center on the straight line L, and at a position beyond the dead center, the projecting piece 40 Abuts against the side wall of the stabilizing member and stabilizes. By the action of the toggle press mechanism 50, the moving rod 35 moves toward the fixed jaw 34, the movable jaw 43 is pressed against the fixed jaw 34 with a strong force, and the workpieces Wa and Wb move. It is strongly clamped between the side jaw 43 and the fixed side jaw 34.

In this embodiment, as in the above embodiment, the handle 37 is located between the operation lever 47 and the fixed member 31, so that the handle 37 and the operation lever 47 can be gripped with one hand. By gripping and rotating the operation lever 47, the workpieces Wa and Wb can be easily held while the jaws are stably positioned at predetermined positions of the workpieces Wa and Wb.

In order to release the clamping, the operation lever 47 is pivotally rotated so as to return to the outside, and the toggle press mechanism 50 exceeds the dead center in the direction opposite to the above, and the shaft 4 is released.
Acting so as to reduce the distance between the movable jaws 4 and 46, the movable bar 35 is lifted, the movable jaw 43 is separated from the fixed jaw 34, and the work W (Wa / Wb) is released from being clamped.

On the other hand, the pinching force of the giant vise, that is, the stroke length of the moving rod 35 when the operating lever 47 is operated, is
The adjustment can be performed by rotating the operation section 47a around the axis.

That is, when the stroke length of the moving rod 35 is shortened to reduce the holding force, the operating part 47a is turned to lower the position of the support member 41, and the shaft 48 and the shaft 4 are moved.
6, the rotation angle at the time of operation of the operation lever 47 is reduced, and the movement width (downward length) of the moving rod 35 is reduced. Therefore, the clamping force of the work between the jaws 34 and 43 is reduced. When increasing the holding force, the operation unit 47
By turning a in the opposite direction to the above, the position of the support member 41 may be raised, the distance between the shaft 48 and the shaft 46 may be increased, and the stroke length of the moving rod 35 may be increased.
