Technical Field

[0001] This utility model relates to the field of fixing fixture technology, and specifically to an assembly fixture that adapts to irregular shapes. Background Technology

[0002] A fixture is a tool or device used to fix, position, and support a workpiece during manufacturing, processing, or assembly. Its main function is to ensure that the workpiece remains stable during operation, thereby improving accuracy, efficiency, and quality.

[0003] Currently, parts usually need to be fixed by fixtures during the production and processing process. There are many types of fixtures. Fixtures can easily loosen, shift position, deform, be damaged or fly out during the processing of fixed workpieces, reducing the intensity of manual labor.

[0004] The prior art includes a Chinese patent with publication number CN220783090U to address the aforementioned technical problems. The technical solution disclosed in this patent document is as follows: It includes a base and a worktable, with a pad connecting the base and the worktable. A first base is connected to the worktable, and a baffle is provided on the first base. A connecting rod is provided between the baffle and the first base, with its left and right ends connected to the first base and the baffle, respectively. A second base is also connected to the worktable, and a cylinder is connected to the second base. A push plate is connected to the extended end of the cylinder. An automatic sensor facing the workpiece placement area is provided between the push plate and the baffle, and the automatic sensor is connected to the worktable. This utility model can prevent irregularly shaped workpieces from shifting during processing, ensuring processing results; reducing manual labor intensity and improving work efficiency. However, it still suffers from mismatch between the fixture and the workpiece shape, and the angle and shape for clamping the workpiece are relatively limited, for example, only adapting to circles or squares. It cannot replace or install clamping structures adapted to different workpiece shapes, affecting the stability and practicality of workpiece clamping and fixing. Utility Model Content
