Table-type medium-frequency mono-side double-point spot welding machine

Abstract

The invention relates to a table-type medium-frequency mono-side double-point spot welding machine. The table-type medium-frequency mono-side double-point spot welding machine comprises a positive electrode spot welding head, a negative electrode spot welding head and a driving device, the negative electrode spot welding head and the driving device are arranged on the side surface of a machine base, the positive electrode spot welding head is arranged at the driving output end of the driving device, the driving device is an air pressure driving rod, and the driving device is connected with anexternal power supply, wherein the positive electrode spot welding head further comprises a positive electrode pressing block, one longitudinal section of the positive electrode pressing block is in an I shape, the positive electrode pressing block is arranged on the air pressure driving rod in a sleeving mode, a pressure-bearing block is arranged on the negative electrode spot welding head, and aplurality of pressure-bearing grooves are formed in the upper end of the pressure-bearing block. Through the arrangement, the table-type medium-frequency mono-side double-point spot welding machine can achieve effects of being capable of improving the bending effect, high in forming speed and capable of improving the working efficiency.

Description

technical field [0001] The invention relates to a table-top intermediate frequency single-sided double-point spot welding machine. Background technique [0002] Spot welding machines are widely used in aviation, aerospace, energy, electronics, automobiles, light industry and other industrial fields, and are one of the important welding equipment. Spot welders can be divided into single-point spot welders and double-point spot welders according to the number of solder joints to be welded; according to the conduction mode, they can be divided into single-side conduction and double-side conduction. In the preparation process of a battery pack, in order to make multiple batteries connected in parallel to supply power, the two poles of the batteries need to be welded together with a nickel sheet with two pins. When welding the nickel sheet and the battery, in order to prevent the battery from exploding due to the current flowing directly from the battery, a single-side conductiv...

AI Technical Summary

Problems solved by technology

However, during the welding process of the double-point spot welding machine in the prior art, since a large amount of current flows from the positive pole to the negative pole through the welded piece, the positive pole spot welding head is easy to produce adhesion with the welded piece

This will not only destroy the welding quality of the welded parts, but also increase the wear of the spot welding head, and even destroy the entire equipment, causing unnecessary losses
