With the rapid development of China's aerospace industry and the increasing number of tasks year by year, the traditional processing methods have been unable to meet the needs of aerospace products with multiple varieties and small batches. It is urgent to find a low-cost and efficient production method. In view of this situation, this paper puts forward a design idea of an intelligent machining unit for aerospace electronics structural parts. Centering on improving equipment startup rate, reducing personnel demand, and improving quality consistency. Following the overall idea of "unified the type of processing method, complete some work offline, improve the flexibility of machining and intelligent decision-making", taking the built intelligent FMC (Flexible Manufacturing Cell) as an example, it realizes continuous and unattended automatic processing of products, Under the premise of ensuring quality, the production efficiency has been improved and good practical results have been achieved.
Aiming at the difficulty in controlling the optical alignment machining accuracy of high-precision thin-walled opto-mechanical parts, a control method based on accurate calculation of clamping force and non-contact online detection of clamping deformation monitoring was proposed. Through theoretical calculation, 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 parts 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 parts and provide reference for solving the similar problems.
