Workpiece welding clamp

Abstract

The invention discloses a workpiece welding clamp which comprises a base and two stand columns fixed to the base. A U-shaped seat is further arranged on the part, between the two stand columns, of the base. Two lower inner spacer parts which are perpendicular to each other and two upper inner spacer parts which are oppositely arranged are arranged between the two stand columns, the included angles between the lower inner spacer parts and the bottom face of the U-shaped seat are 45 degrees, and limiting parts used for limiting workpieces and matched with the upper inner spacer parts are arranged on the tops of the two stand columns. The workpieces are comprehensively fixed through multiple clamping air cylinders in different stations, the welding precision can be ensured while a robot carries out welding, especially the weld penetration phenomenon of the workpieces with very thin materials can be avoided, and the welding quality and the welding efficiency are improved.

Description

technical field

[0001] The invention relates to a workpiece welding fixture, which belongs to the technical field of robot welding. Background technique

[0002] In the past, manual welding was mostly used in the construction machinery industry, which was labor-intensive and the welding quality could not be guaranteed. In recent years, a large number of welding robots have been used to replace ordinary workers for welding, which not only improves the quality, but also increases the output and reduces the cost. In the robot welding process, it is necessary to position the workpiece to be welded according to the required tooling, so that the robot can ensure the welding accuracy during the welding process and improve the welding quality. Especially for some workpieces with very thin material thickness, in order to avoid welding through during welding, the clamping requirements for fixtures are higher. Contents of the invention
