[0002] A fixture is a device used to fix the object to be processed in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a fixture. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process of the process can be called a fixture. A fixture usually consists of a positioning element (to determine the correct position of the workpiece in the fixture), a clamping device, a tool guide element (to determine the relative position of the tool and the workpiece or to guide the direction of the tool), a dividing device (to enable the workpiece to complete the processing of several stations in one installation, and there are two types of rotary dividing devices and linear moving dividing devices), connecting elements, and a clamp body (fixture base).

[0003] In the existing technology, after the clamp fixes the part, if you want to change the processing angle, you need to take down the part and re-clamp it with the changed angle. This operation is very inconvenient and greatly affects the work efficiency of part processing. Therefore, we propose a clamp with adjustable processing angle. Utility Model Content
