Manipulator for welding gun

Abstract

The invention discloses a manipulator for a welding gun. The manipulator comprises a lifting swing air cylinder comprising a hollow piston rod, a peripheral air cylinder body and a piston body positioned between the hollow piston rod and the peripheral air cylinder body, wherein an inner cavity of the air cylinder body is separated into an upper sealing cavity and a lower sealing cavity by the piston body; the two sealing cavities are respectively provided with a guiding sleeve and a pressure air inlet; one end of the hollow piston rod is connected with an output shaft of the swing air cylinder through a meshing gear; the other end of the hollow piston rod is connected with a welding box body for supporting the welding gun; the air cylinder and a swing air cylinder body are connected witha frame, so that the lifting or the swing of the welding gun is achieved; a rotating shaft is arranged in the hollow piston rod; one end of the rotating shaft is connected with an output shaft of a motor; the other end of the rotating shaft is connected with a driving device arranged on the welding box body; the welding gun is connected with a driving belt, so that the back-and-forth movement of the welding gun is achieved; and a press foot of a steel band is arranged on the welding box body through a connecting member. The manipulator has a compact structure and small size, and can be used for conveniently manipulating the automatic displacement of the welding gun in a multi-directional motion direction and automatically welding join gaps among band steels.

Description

technical field [0001] The invention relates to a welding machine, in particular to a control device for a welding torch, which controls the automatic displacement of the welding torch and welds the seams between steel strips. Background technique [0002] At present, my country's economy is in a period of economic transformation. The increase in labor and material costs directly restricts the development of enterprises. It is imperative to improve the automation of enterprise equipment. For example, the special steel core for automobile sealing strips is formed by strip steel forming. During the forming process, the strip steel must be continuously fed, and the joints between each coil of strip steel must be welded at intervals of about 10 minutes. In the prior art, joints between steel strips are manually welded, which has defects such as low production efficiency, poor weld quality, high labor intensity, and waste of steel strips. Contents of the invention [0003] Aim...
