Abstract

The invention discloses an air cylinder of a welding gun. The air cylinder of the welding gun comprises a first air cylinder. The first air cylinder comprises a first cylinder barrel, a first piston,a first piston rod, a front end cover of the first cylinder barrel and a rear end cover of the first cylinder. The rear end cover of the first cylinder barrel is internally provided with a first ventline and a second vent line. The first vent line is provided with a first control valve, and the second vent line is provided with a second control valve. In the process that the first piston is movedto the terminal position from the initial position, the first control valve is in an opening state, and the second control valve keeps a closed state. When the first piston is at the terminal position, the second control valve is switched into an opening state from the closed state, and the first control valve keeps an opening state. According to the air cylinder of the welding gun, by controlling the first piston rod to move slowly, the welding gun on the first piston rod can slowly make contact with a workpiece, the welding force is improved after the welding gun makes contact with the workpiece, deformation of the workpiece is avoided, the welding quality is improved, and the service life of the welding gun is prolonged.

Description

Technical field [0001] The invention relates to the technical field of cylinder parts used in welding torches, in particular to a welding torch cylinder. Background technique [0002] The welding gun cylinder is a cylinder used on the welding gun, and the gun arm of the welding gun is pushed to move or swing through the action of the cylinder to realize welding. [0003] In the prior art, in order to meet the welding force requirements, the welding torch requires a relatively large force, so that the welding torch moves quickly and contacts the workpiece, causing an impact on the surface of the workpiece and the welding torch itself, which reduces the welding quality and shortens the welding torch. Life. Summary of the invention [0004] The purpose of the present invention is to overcome the defects in the prior art and provide a welding gun cylinder that can slowly contact the workpiece, and then increase the welding force after the welding torch contacts the workpiece, so as to ...
