Abstract
The invention discloses a spherical surface float clamping mechanism for a conical clamping jaw. The mechanism is provided with a pedestal (1) and is characterized in that: one end of the clamping jaw (6) is provided with a conical hole (Z), and the other end of the clamping jaw (6) is provided with a convex spherical surface; a sleeve (2) is sleeved with the clamping jaw (6) and the pedestal (1); an inner hole step of the sleeve (2) is clamped on a shaft shoulder of the clamping jaw (6) via a rubber ring (5), and the sleeve (2) and the pedestal (1) are fixedly connected into a whole via four bolts (3); and the convex spherical surface (Q) of the clamping jaw (6) is in fit contact with a concave spherical surface of the pedestal (1), and spherical center radiuses of the convex spherical surface and the concave spherical surface are equal. The clamping mechanism is connected and matched with an automatic clamp, and can perform float clamping on the spherical parts without datum holes to realize the processing of any hole position of the full spherical surface. The mechanism has high efficiency and high precision, and is favorable for the manufacture of a special net rack.
Description
Technical field
The present invention relates to sphere part processing and manufacturing technical field.
Background technology
The part of spheroid class is modal to be the bolt sphere part.Bolt sphere is the part of most critical in the building trade rack, and the quality of its quality influences the rack quality.Bolt sphere all the position, hole may occur in global face arbitrfary point, and angle changes many, the precision height, and difficulty of processing is big.The method of the processing of bolt sphere location is to make a screw thread datum hole before bolt sphere processing earlier at present, realizes that the location clamps.So both increased operation, efficient is low, is unfavorable for that automation clamps; Make processed screwed hole be limited in interior distribution of sphere scope at 270 ° at screw thread datum hole exterior angle again, be unfavorable for the manufacturing of special-shaped rack.
Summary of the invention
It is the circular cone jaw spherical floating clamp mechanism of location datum level with the spheroid periphery that purpose of the present invention provides a kind of.
The present invention is a kind of circular cone jaw spherical floating clamp mechanism, a base 1 is arranged, one end of jaw 6 is a conical bore Z, the other end is protruding sphere Q, sleeve 2 cover upper gripper jaw 6 and bases 1, the endoporus step of sleeve 2 is stuck on the shaft shoulder of jaw 6 by rubber ring 5, and makes sleeve 2 fixedly connected integral body of formation with base 1 by 4 screws 3; The protruding sphere Q of jaw 6 and the spill sphere of base 1 coincide and contact, and both centre of sphere radiuses equate.
Circular cone jaw spherical floating clamp mechanism of the present invention is connected pairing to be used with the automation anchor clamps, and the clamping of can floating to the sphere part of no datum hole realizes the processing of position, any hole of global face, the efficient height, and the precision height helps the manufacturing of special-shaped rack.The present invention is simple in structure, and is easily manufactured, and cost is very low, can be connected use with any anchor clamps.Use can be matched by this mechanism, and according to the blank shape of spheroid cylindrical, the circular cone jaw is realized floating in clamping process, stable contact, and reliable grip, and can self-locking.
Description of drawings
Fig. 1 is a structure chart of the present invention.
The specific embodiment
As shown in Figure 1, circular cone jaw spherical floating clamp mechanism of the present invention is by base 1, jaw 6, and sleeve 2, screw 3, rubber ring 5, compression spring 4 assemblies.One end of jaw 6 is a conical bore Z, and the other end is protruding sphere Q, sleeve 2 cover upper gripper jaw 6 and bases 1, and the endoporus step of sleeve 2 is stuck on the shaft shoulder of jaw 6 by rubber ring 5, and makes sleeve 2 fixedly connected integral body of formation with base 1 by 4 screws 3; The protruding sphere Q of jaw 6 and the spill sphere of base 1 coincide and contact, and both centre of sphere radius Rs (ball) equate.
As shown in Figure 1, disk and circular cone axis OO ' intersection point O that the conical bore Z of jaw 6 and clamped sphere part (indicating) form when contacting ", the centre of sphere O of protruding sphere Q is along the circular cone axis OO ' " scope of ± 5mm that is positioned at range intersections O.
As shown in Figure 1, compression spring 4 is housed in the endoporus of jaw 6 and base 1, the protruding sphere Q of jaw 6 and the spill sphere of base 1 leave the 1mm gap.
Pairing was used about available two covers mechanism of the present invention was connected on the actuating unit of anchor clamps.Part is placed on the middle Primary Location of two cover jaws, drives two jaws by the anchor clamps actuating unit and move to sphere part.Because the cylindrical shape of part is not absolute circle, and form error is arranged, in addition reach 4,5mm, the contact that can not all coincide when jaw contact with part can only be that a certain high putting contacts.In the process that clamps, jaw 6 carries out the space spherical floating, and the conical surface of jaw 6 is contacted with the part cylindrical is reliable and stable; 1mm gap in the clamping subsequently between jaw 6 and base 1 sphere is eliminated, and the protruding sphere of jaw 6 closely contacts with the concave spherical surface of base 1, and under the effect of clamping force, can produce the frictional force self-locking, realizes reliable and stable clamping.
