Description

Technical Field

[0001] The utility model relates to the technical field of mechanical arms, in particular to a mechanical arm for electrical assembly welding. Background Art

[0002] In the production process of modern manufacturing industry, mechanical clamps are widely used in the production process to replace people to complete large-scale, high-quality handling and welding work. Especially in the field of electrical installation, mechanical arms are usually used to clamp the objects to be installed, and then the installation saves manpower greatly. However, when the existing clamping device clamps the irregular surface of the special-shaped workpiece, the clamping force of the clamping device on the different special-shaped workpieces remains constant. Because the workpiece surface has protrusions, the clamping force of the clamping device on the workpiece becomes smaller. Therefore, the clamping stability of the clamping device when grabbing the workpiece with protrusions on the surface is low, and the existing mechanical arm only has a clamping function but no welding function. For this reason, a mechanical arm for electrical installation is needed to improve the above problems. Utility Model Content
