Manipulator for welding

Abstract

The manipulator for welding comprises a base, a supporting piece is arranged on the base, a swing piece is rotationally installed on the supporting piece, a round hole is formed in the swing piece, a welding gun is fixed in the round hole so that the welding gun can swing along with the swing piece, and meanwhile due to the swing of the swing piece, the welding gun can swing along with the round hole. Therefore, the welding gun can swing on the welding seam, a welding pool can cover the whole welding seam, and the problem that due to the fact that an existing mechanical arm and a welding gun are difficult to swing, the welding pool is difficult to adapt to changes of the welding seam is solved. A pressing plate is further arranged on the swing part, one end of the pressing plate is connected with an arranged driving rod, a spring is arranged at the other end of the pressing plate, and the other end of the spring is fixed to the bottom of the supporting part, so that swing of the swing part can be achieved by pressing the driving rod, and meanwhile the spring can promote the swing part to reset. The welding quality of a welding seam can be improved while the welding gun swings in the simplest mode.

Description

technical field [0001] The invention relates to the technical field of industrial welding equipment, in particular to a manipulator for welding. Background technique [0002] At present, the application of manipulators has been widely used. Manipulators are used in various positions such as material handling, product grasping, product cutting and welding, etc., which not only facilitate production, but also solve the problem of labor costs. In the process of product production and processing , It is often necessary to use a welding process to achieve a fixed connection to the product. [0003] However, in the existing welding manipulator, the size of the molten pool is basically preset during welding, so when encountering changes in the weld seam, it is difficult for the molten pool to adapt to the change of the weld seam, resulting in poor quality of the weld seam and prone to unwelded Welding defects such as penetration or undercut or pitting of the weld bead.
