In order to ensure the concentricity accuracy of frame-like thinwalled parts, this paper takes the rotating frame as a machining example. And using the method of finite element simulation and calculation, this paper analyzes the main factors that cause the error of coaxiality of the rotating frame. Because the clamping force of the clamping device causes the deformation of the workpiece, this article is based on the finite element simulation to improve the clamping method. By adding a fixing block at the bottom of the frame and clamping with the fixing block to avoid direct pressure on the rotating frame, the error of frame concentricity caused by the clamping deformation is reduced in this way. Aiming at the error caused by machine error, this paper improves the clamping device and adds the calibration mechanism to correct the machine error and ensure the coaxial accuracy. Through the application of the improved method proposed in this paper, the concentricity error of the rotating frame can be guaranteed within 0-0.005mm.
