[0002] Parts processing is part of the manufacturing process, which mainly refers to processing raw materials into parts or components of specific shapes and sizes through processing methods according to design requirements and technical standards. In order to improve the processing accuracy and stability, the parts will be fixed during part processing. However, the shapes of some parts are inconsistent, and different fixtures need to be replaced during processing. For example, waveguide parts, common parts have a rectangular or cylindrical bottom. During processing, the rectangular parts can be directly fixed by two centered clamps to maintain their stability. However, when the centered clamp is used to fix the cylindrical parts, the contact area between the clamp and the cylindrical parts is small, resulting in unstable fixation of the cylindrical parts, which will affect the processing accuracy and stability. Replacing the fixture is more troublesome and inconvenient for processing parts of different shapes. Utility Model Content

The two ends of the clamping plate 47 The side walls of the end side grooves are rotatably connected to the protruding parts of one end of the two rotating plates 45, and baffles 6 are fixedly installed on the sides of both ends of the clamping plate 47. The sides of the outer ends of the two baffles 6 are respectively in contact with the sides of the two rotating plates 45 close to the electric cylinder 41. The baffles 6 can prevent the rotating plate 45 from deflecting to the other side, thereby improving the stability of the rotating plate 5 when it is parallel to the clamping plate 47. Rubber pads 8 are fixedly installed on the sides of the clamping plate 47 and the two rotating plates 45 away from the electric cylinder 41.
