Description

Technical Field

[0001] The utility model relates to the field of component processing and clamping, and more specifically, to a clamping mechanism for high-precision component welding. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Generally, when welding, the objects to be welded are placed on the flat surface of the workbench. Due to the limitation of the workbench on the standing space of the welding master, it is not easy to start when performing multi-angle welding. Therefore, a clamping mechanism for steel structure welding is needed.

[0003] Chinese patent authorization application number: CN202320304249.6 provides a clamping mechanism for steel structure welding. This solution can flip the steel positioned on the support frame through a flipping mechanism, thereby adjusting the inclination angle to facilitate the welding master to cut in, thereby ensuring the quality of welding.

[0004] However, when clamping parts, especially spherical parts, the clamping pieces and the clamping blocks are prone to displacement and falling off, which may affect the welding of the spherical parts. The welding clamping mechanism mentioned in the above patent can stably clamp regular-shaped square parts when clamping parts. However, when clamping spherical parts, the spherical parts may fall off due to fewer force points, which is not conducive to the welding operation of spherical parts.

[0005] Therefore, in order to solve the above problems, a clamping mechanism for high-precision component welding is proposed. Utility Model Content
