Abstract：The author designed and made an internal lathe tool fixture according to the structure and size of internal lathe tool and machine tool for computer numerical control lathe. It can be directly used without finding the contours. The design of fixture consists of the overall structure, the design and computation of main elements, and manufacture of the fixture. The overall structure is designed by the positioning element, the clamping device, the fixture and the machine connection part. We analyze the principle and function of each part, and give the assembly drawing and actual picture. In the design and computation of main elements, we analyze the principles and methods of our design. By measuring relevant dimensions of CNC lathes and machine inner hole tools, we design and compute the main part of inner hole tool fixture with design drawing. The manufacture of the fixture part includes the production of the inside hole tool and the processing technology.
Key words：computer numerical control lathe；internal lathe tool；fixture
