Description

Technical Field

[0001] The utility model relates to the field of tooling fixtures, in particular to a self-adaptive tooling fixture for detection. Background Art

[0002] A fixture is a device used to fix the workpiece in the correct position during the mechanical manufacturing process. It is usually composed of a positioning element, a clamping device, a tool guide element, an indexing device, a connecting element, and a clamping base. Its function is to quickly, conveniently, and safely install the workpiece. The fixture plays a vital role in mechanical processing. It not only helps the workpiece maintain the correct position, but also ensures the correct relative position between the machine tool, the tool, and the workpiece, thereby improving processing accuracy and efficiency.

[0003] However, most of the tooling fixtures in the existing technology have a simple structure, and the clamping function is achieved by a set of movable sides approaching the fixed side. The part that contacts the workpiece is usually designed as a flat or curved surface structure, which can only adapt to the clamping operations of most general workpieces. When there is an irregular structure on the outer surface of the workpiece, it cannot stably clamp and detect the workpiece, and the workpiece is prone to sliding and offset. Therefore, we need to upgrade and transform the existing technology to overcome the existing problems and shortcomings. Utility Model Content
