Description

Technical Field

[0001] The utility model relates to the technical field of product jigs, in particular to a universal jig for precision machining. Background Art

[0002] Jigs are a broad category of tools used in carpentry, ironwork, locksmithing, mechanics, electronic control, and other crafts. They are primarily used to control position or movement. Jigs can be categorized into three types: process assembly jigs, project testing jigs, and circuit board testing jigs.

[0003] The patent with announcement number CN216399329U in the prior art discloses a universal jig for precision machining, including a base, a support plate and a top plate, wherein the support plate is installed at the upper end of the base, and the top plate is inserted into the inner wall of the support plate. It also includes: a first clamping mechanism and a second clamping mechanism, the first clamping mechanism is installed on the right side of the support plate, and the second clamping mechanism is installed on the left side of the support plate. The first clamping mechanism is a rotating rod, which is inserted into the inner wall of the top plate. A supporting frustum is installed at the lower end of the rotating rod, and the side ends of the supporting frustum are respectively provided with a first through hole and a second through hole, and the upper end of the supporting frustum is provided with a third through hole. The beneficial effect of the utility model is that by setting a jig suitable for various types of products, it has a wide range of applications and can simultaneously clamp products of different shapes for processing.

[0004] In the second reinforcement mechanism of this patent, a screw and a clamping seat are used to clamp the workpiece, but when clamping, the screw needs to be rotated to adjust the distance between the two clamping seats. When the screw rotates, it will also drive the clamping seat to rotate. When the clamping seat rotates, the clamping direction will change, which is not convenient for clamping the workpiece. In addition, the shape of the workpiece clamped by this patent is limited, and it cannot adapt to the shape of different workpieces by replacing the clamping head. Therefore, a universal jig for precision machining is needed. Utility Model Content
