Design And Research Of Car Clutch Cover Assembly Detecting Line Layout And Clamping Manipulator

The automobile clutch cover assembly is the core component of the clutch.The load capacity,separation capacity and stability of the cover assembly are directly related to the safety of the transmission system and even the whole vehicle.At the same time,the cover assembly is also a vulnerable component.To ensure its safety,the relevant standards require that it must be tested before leaving the factory.The foreign test equipment is expensive,the enterprise is difficult to bear,and the domestic test equipment technology is not yet fully mature.Therefore,the clutch cover assembly inspection device has an extremely wide application space and prospects.With the support of the actual project of the enterprise,we carry out layout design and balance improvement on the inspection line of the cover assembly,design the structure,simulation analysis of the clamping mechanism of the detection device,and design the control system and the control system of the robot.The work is as follows:Firstly,the domestic and international test lines and testing equipment are compared,and the problems of the current layout line layout and detection devices and the imbalance of the test stations are analyzed.Through the study of the design of the test line layout,the improvement of the upper and lower workpiece devices,the design of the test line device,and the decomposition and merging of the work contents of the bottleneck process(balance,deduplication and marking).Finally,a set of balance improvement schemes was determined,which solved the problems of low automation degree,long test tempo,poor balance,high labor intensity and low detection efficiency.Secondly,the working principle of the detecting device and the effective working space of the detecting line are analyzed.In order to simulate the true effect of the push-type clutch cover assembly on the diaphragm spring under the real working condition,a separate bearing clamping manipulator is designed.This design mechanism solves the problems of the current structure of the grabbing mechanism being large,the dexterity is poor,the grasping of the beat is long,and it is difficult to automatically lock.The CATIA software is used to model and virtualize the manipulator,and the finite element analysis of the key components of the manipulator is carried out in combination with the actual working conditions.The finite element meshing of the geometric model is carried out by using HyperMesh software.The stress and strain and displacement diagram of the opening and closing lock plate are obtained by applying the corresponding constraints and loads.The results show that the workpiece design is reasonable and can meet the strength requirements.The modal analysis of the jaws shows that the jaws do not resonate with the detection device,verification of the rationality of the robot design.Finally,the overall scheme of the detection equipment control system is designed,the selection and research of each control module part is carried out,and the hardware model of the detection equipment is determined,designing a control system for the clamping robot of the detecting device,and constructing a pneumatic control circuit.Based on this,the research on the robot control system and control program is carried out to meet the requirements of the control system accuracy.In order to facilitate the control and troubleshooting of the manipulator,a manual/automatic control module and a fault alarm module were designed to meet the production needs.
