In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process in the process can be called a fixture, such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc.; Among them, tubular objects are the most common type of processing objects. In the process of tubular steel structure production and processing, corresponding fixtures are often required to fix and clamp the tubular steel structure; traditional tubular fixtures manually control two clamping parts to clamp and fix the tubular object on the fixture, and move it to the processing site for processing. In the process of clamping the tubular object by manually controlling the two clamping parts, the locking force on each fixture is inconsistent, which makes some tubular objects prone to deformation due to clamping force, resulting in poor product yield.
[0003] The existing tubular object clamp has recesses on two clamping parts, and the recesses of the two clamping parts cooperate to form a positioning area that matches the shape of the tubular object, so that the tubular object is clamped and positioned on the positioning area, thereby avoiding the phenomenon of deformation of the tubular object due to clamping force; however, the structural design of the tubular object clamp is poor. Since the positioning area formed by the two clamping parts matches the shape of the tubular object, the positioning area has poor clamping firmness for the tubular object, causing the tubular object to shake due to force during processing, thereby affecting the processing accuracy of the tubular object, resulting in rework or scrapping of products due to poor product quality, reducing the production efficiency of the product, failing to meet the user's usage needs, and having a small scope of application.
[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

The mounting plate is connected to a displacement device to control the seat body to move back and forth between the processing position, the position to be processed, and the position of the finished product.
