Description

Technical Field

[0001] The utility model relates to a jig, in particular to a flexible jig for processing precision hardware parts, belonging to the technical field of hardware part processing. Background Technique

[0002] A jig is a large category of tools for carpenters, ironworkers, fitters, machinery, electronic control, and other handicrafts. It is mainly a tool for assisting in controlling position or movement (or both). Jigs can be divided into three categories: process assembly jigs, project test jigs, and circuit board test jigs. According to the classification of jigs, jigs can be divided into three categories: process assembly jigs, project test jigs, and circuit board test jigs.

[0003] The currently publicly known flexible and adjustable tooling jig with the publication number CN217394907U includes a bottom plate. A first bearing is inlaid at the center of the upper end of the bottom plate. The inner ring wall of the first bearing is fixedly connected with a support tube. A support rod is slidably connected inside the support tube. The upper end of the support rod passes through the pipe orifice of the support tube and extends upward and is provided with an operating table. The support tube and the support rod are connected by bolts. A clamping assembly is installed at the upper end of the operating table. A rotating disk is sleeved on the pipe wall of the support tube. A plurality of limiting holes are evenly and equidistantly arranged on the side wall of the rotating disk, and the plurality of limiting holes are annularly distributed. A limiting tube is connected to the upper end of the bottom plate.

[0004] In the above scheme, although there are many benefits, there are also the following disadvantages: Although the clamping of the object is achieved, the rotation angle adjustment of the object to be processed cannot be realized. In addition, the movement of the support rod will drive the operating table to move in the vertical direction. When the operating table moves to the designated position, then turn the bolt to fix the support rod in the support tube. However, the lifting of the operating table requires manual operation by personnel, which will waste the physical strength of the personnel and reduce the practicability of the device.
