[0031] The working principle and usage process of the present utility model: For the chuck for processing high-precision roundness parts, before processing and production, when the chuck body 100 is first fixed on the equipment for use, the roundness part to be processed is placed on the upper surface of the main disk body 101 and supported on the surface of the support table 104. And the guide post 102 is moved to engage the chuck 103 and the chuck plate 1031 on the surface of the roundness part, so as to facilitate the chuck body 100 to engage and fix the roundness part for processing and production;

[0032] Then, before the chuck body 100 clamps and fixes a roundness part, the clamping plate 1031 is clamped inside the installation groove 1032 by clamping the clamping block 1033 inside the clamping groove 1034. After the clamping plate 1031 is clamped on the inner surface of the clamping jaw 103, the connecting pressure plate 1038 is closed again on the surfaces of the two fixed threaded rods 1037 and is inside the connecting groove 1035. Then, the fixing nut 1036 is rotated at the end of the fixed threaded rod 1037 to fixedly install the connecting pressure plate 1038, so that the clamping plate 1031 is fixed inside the clamping jaw 103 for use. When the clamping plate 1031 is frictionally damaged due to the frequent clamping of roundness parts by the chuck body 100, the reverse operation can be performed to disassemble and replace the clamping plate 1031, which is convenient for the partial replacement of the clamping jaw 103. The replacement is more convenient, material waste is not easily caused, and the clamping is more accurate and fixed during clamping, which is convenient for high-precision machining. It improves the convenience of partial replacement of the clamping jaw 103 when the chuck body 100 frequently clamps and fixes roundness parts and saves materials.

[0033] Finally, when the chuck body 100 is frequently operated, oil can be injected into the oil inlet channel 1022 through the oil injection port 1021, and the rotary sealing cover is rotated to seal and fix the oil injection port 1021. After the oil injection channel 1022 is filled with oil, it enters the oil inlet 1024 again and soaks into the oil inlet sponge 1025. When the movable connecting guide post 102 is moved, the oil inlet sponge 1025 is squeezed, and oil lubrication operation is performed on the inner surface of the guide post 102 and the main disc body 101. Thus, friction is not easily generated during the frequent movement of the guide post 102, and the movement and adjustment are smooth and more convenient. It improves the convenience of lubricating the movement of the guide post 102 when the chuck body 100 clamps and fixes roundness parts during machining.
