Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage cabinet door processing, in particular to a double-sided fastening fixture for high-voltage cabinet door processing. Background Art

[0002] Jigs are a large category of tools for carpentry, ironwork, fitter, machinery, electronic control and some other handicrafts. They are mainly used as a tool to assist 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. When processing high-voltage cabinets, due to the large size of the cabinet door, in order to ensure the processing accuracy, it is usually necessary to tighten the jig to fix it and ensure the stability of the processing.

[0003] For example, a double-sided fastening fixture for processing high-voltage cabinet doors with the authorization announcement number CN212887269U, the above document uses four clamping blocks to perform preliminary positioning work on the door panel, and later uses the cylinder to drive the clamping plate to descend, thereby completing the clamping work of the door panel. During the entire working process, there is no need to manually adjust the position of the door panel, which reduces the difficulty of clamping, and the clamping process is simple, which improves the clamping effect and speed. However, during the use of the double-sided fastening fixture in the above document, the double sides of the high-voltage cabinet door are fastened by the elastic force of the spring after deformation on the clamping block. However, due to long-term use, the elasticity of the spring is easily weakened, which makes the clamping block loose on the high-voltage cabinet door, making the high-voltage cabinet door easily deviate, thereby affecting the fastening effect of the high-voltage cabinet door;

[0004] Also, during the use of the bilateral fastening fixture in the above-mentioned document, the positions of the clamping plates on both sides are adjusted manually by the staff, and the positions of the clamping plates cannot be automatically adjusted, so that during the processing of the high-voltage cabinet doors, the positions of the clamping plates need to be repeatedly adjusted, which makes the processing of the high-voltage cabinet doors more cumbersome, affecting the delivery efficiency of the high-voltage cabinet doors. Utility Model Content
