[Abstract]:At present, the large size assembly of servo mechanism still adopts the traditional manual assembly method. Sealing assembly is the key link. The assembly parameters can not be quantified and assembly tools are easy to be assembled by manual experience and subsequent verification. Therefore, the automatic assembly technology of large size components of servo mechanism is studied. First of all, the assembly process and the key technology to realize the automatic assembly system are analyzed. The research contents are refined, including the design of assembly equipment, the simulation of sealing assembly and the intelligent fixture of "perceptible force", and the overall technical route is put forward. In order to ensure that the precision of the equipment meets the requirements, the precision of the automatic assembly system is analyzed. Secondly, aiming at the problem that the assembly quality of sealing parts can not be judged in real time during the sealing assembly of large size components of servo mechanism, a method to establish the assembly force prediction model of sealing structure is put forward. The finite element analysis model of assembly force is established, the key factors affecting assembly force are analyzed, and the specific parameters of the model are determined in combination with the press loading test. The results show that the predicted model results are the same as the experimental results, and the rationality of the prediction model is verified. Finally, the envelope range of assembly force-assembly path curve under normal assembly state of sealing parts is obtained, which provides a basis for real-time monitoring of sealing assembly quality. Then, the intelligent points of the fixture which can be further studied are analyzed, and according to the existing conditions and the research background, the intelligent fixture to further study the "perceptible force" is determined, and the three-dimensional force sensor is arranged on the basis of the fixture scheme of the equipment. In this paper, the realization of "perceptual force" of the fixture is studied, and the detailed theoretical mechanical analysis is carried out, and the mathematical model of the force on the contact point of the workpiece is obtained, and the feasibility of the research point is preliminarily verified theoretically. Finally, the overall development scheme of the equipment is summarized, the working principle of the equipment is summarized, and the key components of the equipment, the system measurement scheme and the control scheme are described in detail. The sealing simulation and intelligent fixture experiments were carried out respectively, and the experimental data were processed and analyzed.
