Background

The tool is a large tool for woodworking, ironwork, bench workers, machinery, electric control and other handicraft articles, and is mainly used as a tool for assisting in controlling position or action. The jig can be divided into three types, namely a process assembly jig, a project test jig and a circuit board test jig.

In the field of laser welding, it is often necessary to weld a welding widget to a welding body. Before welding, the welded small piece needs to be pressed onto the welding main body, and then laser welding is performed, specifically: be used for welding smallclothes department to be equipped with the boss on the welding main part, welding main part and welding smallclothes are in the separation state before the welding, place the welding smallclothes on the boss of welding main part earlier during the welding, with the welding smallclothes pressfitting on the boss of welding main part, the rethread welding can be with the welding smallclothes welding to the welding main part on.

The existing jig can achieve tight press fit aiming at single elastic piece welding, and when a plurality of small welding pieces are required to be welded on a welding main body, two methods are generally adopted for solving the problem. The method comprises the following steps: and (3) clamping for multiple times, and welding one part after each clamping until all the welding small parts are welded on the welding main body. The second method is as follows: all the welding small pieces are clamped at one time, and then all the welding small pieces are welded to the welding main body at one time. The method is time-consuming, and the machining efficiency is low due to repeated clamping and welding. When a plurality of welding small pieces are at different heights, the gap between each welding small piece and the welding main body cannot be ensured to be uniform at the same time due to the existence of machining precision and product tolerance. When the gaps between the welding small pieces and the welding main body are uneven, the problems that the welding is blackened, the virtual welding is generated, the welding drawing force cannot be guaranteed and the like can be solved, and then the welding effect is poor.
