Description

Technical Field

[0001] The present invention relates to the technical field of welding, and in particular to an adjustment slide and welding equipment. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that uses heat, high temperature, or high pressure to join metals or other thermoplastic materials, such as plastics. With the advancement of automation technology, automated welding equipment has gradually emerged, especially full-position automatic welding equipment. Due to its ability to perform fully automatic circumferential welding, it is widely favored by major manufacturers.

[0003] However, the full-position automatic welding equipment needs to adjust the rotation center of the welding head to the rotation center of the workpiece before welding. The structure of the existing adjustment mechanism is relatively complex, and the overall structure is relatively thick and heavy, occupying a large space of the welding equipment. Summary of the Invention

[0004] The problem to be solved by the present invention is: how to provide an adjustment slide with a simple structure and small space occupation.

[0005] To achieve the above object, the technical solution of the present invention is as follows:

The welding head needs to perform two-dimensional position adjustment of the welding gun rotation center during circumferential welding. Since a longitudinal slide rail is provided between the fixed plate and the longitudinal adjustment plate, the longitudinal adjustment plate can be driven by the first driving member to move longitudinally along the fixed plate.
