Welding tool equipment

Abstract

The invention provides welding tool equipment. The welding tool equipment comprises a base assembly, an upper electrode assembly and a lower electrode assembly. The base assembly is fixed. The upper electrode assembly comprises an upper electrode head. When the upper electrode head moves to the stroke end point in the direction of the base assembly, a welding space is formed between the bottom face of the upper electrode head and the base assembly. The lower electrode assembly comprises two or more lower electrodes. When the two or more lower electrodes move to the stroke end point towards thewelding space, the welding space is surrounded by the two or more lower electrodes, and the two or more lower electrodes are combined to form a lower electrode head. The welding pressure of the welding tool equipment is provided by the upper electrode head and the base assembly, the position of the lower electrode head can be freely arranged, and good practicality is achieved.

Description

technical field [0001] The invention relates to the field of welding, in particular to a welding tool. Background technique [0002] Resistance welding refers to the method of using the resistance heat generated by the current passing through the weldment and the contact as the heat source to locally heat the piece and simultaneously pressurize it for welding. [0003] figure 1 A structural schematic diagram of a compressor is shown. In the industry, in order to realize the external installation of the compressor 501 , it is usually necessary to weld a compressor base 502 on the bottom of the compressor 501 . At present, gas shielded welding is usually used in the industry, but the use of gas shielded welding, on the one hand, has a high welding defect rate, on the other hand, due to high heat, the welding heat affected zone is large, resulting in deformation of the mechanical part of the compressor, affecting the efficiency of the compressor and even cause the compressor...

AI Technical Summary

Problems solved by technology

[0005] It can be seen from the structure of the above-mentioned conventional resistance welding welding equipment that when the conduction between the two welding electrodes is realized, the conduction current will pass through the large-area compressor shell, and may flow through the mechanical components inside the compressor; Under the thermal effect of the current, the heat-affected zone of the existing resistance welding equipment during welding is relatively large, which easily leads to deformation of the compressor shell and mechanical parts inside the compressor shell, affects the working efficiency of the compressor, and may cause cause compressor failure
