Description

Technical Field

[0002] With the trend of industrial intelligence development in recent years, more and more product production is constantly changing from traditional manual operation to semi-automatic and fully automated equipment production lines, and the degree of automation will become higher and higher. In the integration of automated equipment production lines, automated production fixtures are an indispensable part.

[0003] When assembling, positioning, and welding automobile components, it is often necessary to use multiple positioning fixtures in different processes. The current solution to the problem of needing multiple positioning fixtures is mainly to use a slide structure, which requires two or more guide rails, multiple cylinders, and a large-diameter telescopic cylinder to push the slide. This solution has the following main disadvantages: 1. The tooling structure is complex and occupies a large space, which is not conducive to the arrangement of the mechanism in a small space; 2. There are many supporting auxiliary parts, such as stop blocks, guide rail floors, etc.; 3. The processing cost is high, and more auxiliary parts and purchased parts are required; 4.
