Description

Technical Field

[0002] In modern manufacturing, welding processes are widely used for the connection and assembly of parts. However, accurately positioning parts to ensure welding quality and accuracy has always been an important challenge during the welding process. Traditional welding methods often rely on manual experience and simple fixtures to position parts. But this approach has many defects. First, the accuracy of manual positioning is difficult to guarantee, and it is easily affected by the operator's skill level and working status, resulting in welding position deviation, which affects the overall quality and performance of the product. Secondly, simple fixtures have limited functions and cannot adapt to parts with complex shapes and various sizes, which limits the flexibility and efficiency of production. With the continuous development of the manufacturing industry, the accuracy, quality and efficiency of parts welding are increasingly required. Especially in some industries with high precision and high performance requirements, inaccurate welding positioning may cause serious safety hazards and quality problems.

[0003] In order to solve the problem that "the existing positioning devices need to be improved in terms of operational convenience", the Chinese patent with publication number CN118455900B discloses a component welding positioning device, including two symmetrically arranged mounting rails, two movable base plates are slidably connected to the two mounting rails, each movable base plate is installed with a positioning seat, the end surface of the positioning seat is provided with a truncated cone groove, and the outer side wall of each positioning seat is installed with a first servo motor, the output end of the first servo motor extends into the truncated cone groove and is installed with a moving component, and a locking component is installed on the moving component. Although the existing technical problems have been solved, the following problems still exist: In this technical solution, when welding, it is necessary to insert the tubular component into the corresponding positioning seat, and then fix the component by the locking assembly, and then drive the two positioning seats closer together by the slide rail until the ends of the two components touch each other.
