Double-sided spot welding system

Abstract

The invention relates to a double-sided spot welding system which comprises a U-shaped plate feeding conveying belt, two side plate feeding devices, a side plate feeding mechanical arm, a spot weldingmain machine and a discharging mechanical arm. The spot welding main machine is fixedly installed on an operation cabinet, and the two side plate feeding devices are symmetrically and fixedly installed on the left side and the right side of the spot welding main machine, the side plate feeding mechanical arm is fixedly installed above the spot welding main machine and between the two side plate feeding devices through a support, a U-shaped plate feeding conveying belt is installed in front of the spot welding main machine, a U-shaped plate feeding mechanical arm is installed above a tail section of the U-shaped plate feeding conveying belt, and a finished product discharging mechanical arm is installed behind the spot welding main machine; and the spot welding main machine comprises a spot welding clamping rotating device and a spot welding gun swinging device. According to the double-sided spot welding system, programmable automatic feeding of a control cabinet is adopted, double-face spot welding of one welding gun can be achieved, the manual labor intensity is low, and the production efficiency is high.

Description

technical field [0001] The invention belongs to the field of component welding, and relates to welding equipment, in particular to a double-sided spot welding system. Background technique [0002] In recent years, with the development of digitization, automation, computer and mechanical design technology, and the high emphasis on welding quality, automatic welding has developed into an advanced manufacturing technology, and the role played by automatic welding equipment in the application of various industries Increasingly, the scope of application is rapidly expanding. In modern industrial production, the mechanization and automation of the welding production process is an inevitable trend in the modernization of the welding mechanism manufacturing industry. [0003] When the automatic welding equipment is working, it usually uses a manipulator to transfer the material to be welded to the designated position and then clamps and limits it, so that the weldment is fixed to t...

AI Technical Summary

Problems solved by technology

Traditional automatic welding equipment usually uses a manipulator to transfer the material to the designated position before welding. However, the material used for welding is often flat, and the manipulator is not easy to pick it up. Therefore, it is usually used for manual loading, which leads to low production efficiency and high labor intensity. and high production cost

However, the clamping device often has a difference between the clamping position and the predetermined position, which will cause a deviation in the mounting position, and the unevenness of the gap will cause the welding pressure to fluctuate, which will cause a significant difference in the strength of each solder joint. Causes severe splashing, resulting in high scrap rates

At the same time, the existing automatic spot welding equipment is generally linear spot welding, while the curved spot welding mostly uses spot welding robots. The former has poor applicability, while the latter often has a complex structure and high production and maintenance costs.
