Abstract
As a key link in the field of mechanical manufacturing, the definition of high-precision mechanical assembly covers the precise coordination and connection of mechanical parts by means of high-precision. This technology is characterized by its high precision, high reliability and high stability, and is developing in the direction of automation, intelligence and miniaturization. However, in practical application, the influence of part machining error on the assembly accuracy cannot be ignored, and the size error, shape error and position error will have a significant impact on the final assembly effect. By deeply analyzing the technical difficulties of high-precision mechanical assembly, we found that the problems such as insufficient machining accuracy of parts, high complexity of assembly process, inaccurate control algorithm, inaccurate parameter setting and improper handling of non-linear factors all pose challenges. In addition, the difficulty of system integration is also an important factor restricting the development of high-precision mechanical assembly technology. In order to optimize the high-precision mechanical assembly technology, a series of countermeasures should be adopted. Firstly, the precision of processing equipment should be improved to ensure the accuracy of parts processing; secondly, simplify the assembly process and reduce the complexity of the control algorithm model to improve control precision and stability; Moreover, adopt parameter optimization method and nonlinear modeling to better handle the nonlinear problems in the actual assembly process; finally, strengthen system integration test to ensure the coordination and cooperation among the components. Through the implementation of these optimization countermeasures, it is expected to further improve the precision and efficiency of high-precision mechanical assembly, and promote the sustainable development of mechanical manufacturing field.
