Description

Technical Field

[0001] The utility model relates to the technical field of bolt processing fixtures, in particular to a special fixture for processing anti-dropping bolts. Background Art

[0002] The anti-drop bolt is a mechanical part, mainly composed of a head and a screw. This part needs to be used with a nut to fix the connector. During the processing of the anti-drop bolt, there will be errors between some processed bolts and standard bolts, so the anti-drop bolt needs to be clamped with a fixture and then polished again. However, when the existing fixture clamps the anti-drop bolt, due to the lack of a support device for the anti-drop bolt, the anti-drop bolt is suspended, which makes it inconvenient to reprocess the anti-drop bolt.

[0003] For example, a bolt processing fixture with Chinese patent application number CN202321277690.6 has a connecting block fixedly connected to the upper part of the connecting rod, and first hinge components parallel to the clamping table are symmetrically arranged on both sides of the connecting block, and the end of the first hinge component away from the connecting block is rotatably connected to the first connecting bar, and the end of the first connecting bar away from the first hinge component is rotatably connected to the L-shaped connecting frame, and the connecting frame is rotatably connected to the clamping table through a second hinge component arranged on the side wall of the clamping table, and the end of the connecting frame that passes through the clamping table and extends out of the clamping table is rotatably connected to the second connecting bar, and the end of the second connecting bar away from the connecting frame is hinged to the clamping slide slidably arranged on the top of the clamping table. It has the following technical defects:

[0004] When clamping and reprocessing the anti-dropping bolts, it is necessary to manually support the anti-dropping bolts, and then use the cylinder to control the two clamping slides to clamp the anti-dropping bolts. The manual support process of the anti-dropping bolts is not only time-consuming and labor-intensive, but also inconvenient to quickly clamp the anti-dropping bolts, which can easily affect the processing efficiency of the anti-dropping bolts.
