|Aiming at the difficulty in controlling the optical alignment machining accuracy of high-precision thin-walled opto-mechanical components, a control method based on accurate calculation of clamping force and non-contact online detection of clamping deformation monitoring was proposed. Through theoretical calculation and finite element simulation, the clamping force values under three working conditions of centering processing are obtained, and a real-time detection system for clamping deformation is built. Measures such as establishing a high precision-connection surface and accurately adjusting the screw tightening torque of the clamping process are adopted to control the clamping deformation of the opto-mechanical components, and estimate the machining accuracy of the opto-mechanical components online. Experiments show that this method can realize the design accuracy index of opto-mechanical components and provide reference for solving the similar problems.
