Problems solved by technology

[0002] The traditional welding system uses a tandem robot to move single-sided double-point spot welding welding tongs. The rigidity of the tandem robot is poor, and the welding reaction force during welding is likely to cause the reverse displacement of the electrode, resulting in unstable welding pressure and affecting the quality of the solder joints. In addition, the traditional The welding system uses a cylinder to adjust the electrode spacing, and the adjustable distance is fixed

Abstract

The invention provides a novel flexible single-face double-point spot welding system and technology. The novel flexible single-face double-point spot welding system comprises a robot rack, a plurality of robots, an electrode holder, an electric cylinder and a welding clamp. The robots are arranged on the robot support. The welding clamp is fixedly arranged on the ground and used for clamping a workpiece and transmitting welding current. The electrode holder is arranged at the lower ends of the robots. The electrode holder comprises a static electrode and a dynamic electrode. The preset distance of the static electrode and the dynamic electrode is adjusted under driving of the electric cylinder, series air cylinders drive the static electrode and the dynamic electrode to a welding point, a welding transformer provides welding current, and welding work of a to-be-machined workpiece is finished. A parallel structure is adopted in the installing robots, pressure is directly applied to the electrode holder, the structure rigidity of the whole machine is very high, very large welding counter acting force can be borne, reverse movement of the motor is effectively prevented, the position of the motor is stable, the welding pressure is stable, and the welding efficiency and the welding quality are greatly improved.

Description

technical field [0001] The invention relates to the technical field of spot welding, in particular to a novel flexible single-sided double-point spot welding welding system and process. Background technique [0002] The traditional welding system uses a tandem robot to move single-sided double-point spot welding welding tongs. The rigidity of the tandem robot is poor, and the welding reaction force during welding is likely to cause reverse displacement of the electrode, resulting in unstable welding pressure and affecting the quality of solder joints. In addition, the traditional The welding system adopts a cylinder to adjust the electrode spacing, and the adjustable distance is fixed. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to propose a new type of flexible single-sided double-spot spot welding welding system and process, which improves the work efficiency and welding quality of the spot welding system as a...
