A carbon brush lead wire and connecting bridge welding device

Abstract

The invention provides a carbon brush lead wire and connecting bridge welding device, which includes a machine base, and also includes a welding mechanism, a welding piece positioning mechanism and a welding spot transfer mechanism. The welding mechanism, the welding piece positioning mechanism and the welding spot transfer mechanism are arranged on the base Above, the welding piece positioning mechanism is used to keep the relative position of the carbon brush and the connecting bridge to be welded fixed, and the welding spot transfer mechanism is connected with the welding piece positioning mechanism and can drive the welding piece positioning mechanism to change the position so that the lead wire of the carbon brush and the connecting bridge are connected. Each to-be-welded point corresponds to the welding mechanism respectively. In the present invention, the positioning mechanism of the welding part pre-determines the positions of the carbon brush and the connecting bridge. When welding, the carbon brush and the connecting bridge only need to be placed in place without further adjustment, and the welding can be completed quickly and accurately, so the working efficiency can be greatly improved. And it can improve the welding quality of components inside the carbon brush holder.

Description

technical field [0001] The invention relates to a welding tool, more specifically, it relates to a carbon brush lead wire and connecting bridge welding device. Background technique [0002] The carbon brush holder is an important part of the electrical circuit and is widely used in automatic mechanical equipment and production lines. Its function is to apply pressure to the carbon brush that is in sliding contact with the surface of the commutator or collector ring through the spring to make it fixed The current is stably conducted between the body and the rotating body. On different devices, carbon brush holders have different structural forms, such as figure 1 In the shown carbon brush holder, four carbon brushes surround the collector ring, two adjacent carbon brushes are connected in parallel on a connecting bridge and then a lead-out line is drawn out from the connecting bridge, and the two carbon brushes are connected to the connecting bridge. There are two solder jo...

AI Technical Summary

Problems solved by technology

[0003] The welding between the carbon brush and the connecting bridge inside the existing carbon brush holder lacks suitable fixtures, resulting in low operating efficiency and unstable welding and assembly quality. Quality carbon brush leads with bridge soldering device

With the help of the present invention, the relative position of the carbon brush and the connecting bridge can always be kept fixed during the welding process, and the consistency of the welding process of the product can be maintained even between different processing batches. This leads to problems such as improper control of the distance between the carbon brush and the connecting bridge, distortion of the lead wire of the carbon brush, and uncertain position of the solder joint, thereby ensuring stable welding quality
