Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a jig for processing special-shaped parts. Background Art

[0002] Special-shaped parts processing jigs are tools or devices used to assist in the processing of non-standard shaped parts. Compared with standard shaped parts, special-shaped parts have more complex shapes and may contain irregular contours, special curved surfaces or complex internal structures.

[0003] Chinese patent publication number CN207387156U, publication date 20180522, discloses a quick clamping fixture for aluminum castings, including a base plate, a support system and a clamping mechanism, wherein the base plate is a large horizontal flat plate, the support system is an air-supporting mechanism arranged directly above the base plate, and the clamping mechanism is a pneumatic rotary clamping and fixing mechanism arranged on the base plate close to the support system. The clamping mechanism includes at least 6 pneumatic rotary clamping and fixing mechanisms, and the aluminum casting workpiece is placed flat on the upper surface of the support system, and the pneumatic rotary clamping and fixing mechanism clamps and fixes the aluminum casting workpiece from four sides.

[0004] Existing casting quick clamping jigs such as the above-mentioned ones mostly fix the castings through multiple sets of positioning components. In the specific implementation process, since the existing casting quick clamping jigs are mostly based on the external contour settings of conventional castings, the multiple sets of positioning components are mostly based on the same horizontal plane, and the external contours of some special-shaped parts are relatively irregular. Conventional casting quick clamping jigs are often unable to stably complete the positioning of special-shaped parts. Therefore, it is urgent to propose corresponding special-shaped parts processing jigs to solve the above problems. Utility Model Content

The tool clamps include a lateral positioning seat, a transverse positioning seat and a limit pin fixedly connected to the tool positioning plate. A positioning locking block and a limit assembly for limiting the positioning locking block are integrated between the lateral positioning seat, the transverse positioning seat and the limit pin. The side of the lateral positioning seat and the transverse positioning seat close to the positioning locking block are integrated with a plane dynamic steel ball positioning head and a push-pull assembly for pushing and pulling the plane dynamic steel ball positioning head. The open end of the plane dynamic steel ball positioning head is engaged with a rolling steel ball.

[0008] Preferably, the push-pull assembly consists of a lateral push rod and a longitudinal push rod, and the lateral push rod and the longitudinal push rod are respectively screwed together with the lateral positioning seat and the inner wall of the transverse positioning seat, and the open ends of the lateral push rod and the longitudinal push rod are respectively fixedly connected with multiple groups of planar dynamic steel ball positioning heads.

[0012] Preferably, the limiting assembly includes a clamping screw screwed together with the tooling positioning plate, and the clamping screw vertically passes through the positioning locking block.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
