Feeding mechanism of intermediate-frequency inversion spot welder

Abstract

The invention provides a feeding mechanism of an intermediate-frequency inversion spot welder, and belongs to the technical field of spot welders. The problem that the welding quality is low in the prior art is solved. According to the feeding mechanism of the intermediate-frequency inversion spot welder, the intermediate-frequency inversion spot welder comprises a work box, a cavity is formed inthe work box, and a rotating disc is rotationally arranged at the top of the work box and provided with four welding tables; the four welding tables are distributed annularly at equal distances, and afirst lower electrode and a second lower electrode are arranged in each welding table; welded objects comprise first parts, second parts and third parts, each second part is welded to one end of thecorresponding first part, and each third part is welded to the other end of the corresponding first part; and the feeding mechanism can feed the second parts to the welding tables and comprises a second air cylinder, and a cylinder body of the second air cylinder is fixed to the work box. The feeding mechanism has the advantage of improving welding quality.

Description

technical field [0001] The invention belongs to the technical field of spot welding machines, and relates to a feeding mechanism of an intermediate frequency inverter spot welding machine. Background technique [0002] The spot welding machine has the following advantages: high welding stability; power saving of more than 30%, low operating cost; three-phase power supply balanced input, power factor up to 95%; lower welding current and electrode pressure; secondary circuit has almost no induction energy Loss; more than double the electrode life, reduce electrode grinding time; greatly save the installation cost of power installation and water, gas and other auxiliary facilities; more accurate, faster and more comprehensive control and analysis of welding parameters; shorter welding time , improve work efficiency and welding quality; the welding range is wider, and the welding effect on low carbon steel, stainless steel, copper, aluminum, and galvanized sheet is better; [0...

AI Technical Summary

Problems solved by technology

[0003] Most of the spot welders on the market can only weld two parts. Some specific welders require three parts to be welded. As a result, most spot welders cannot complete high-quality welding work. There are many welded parts and the transportation It is the key issue. Whether the parts can be delivered to the welding station quickly and accurately is a technical problem to be solved by those skilled in the art.
