Research On The Design Of Multi Position Processing System For The End Cap Of Automobile Generator With Robot And Production Line Optimization Technique

With the rapid development of China’s automobile manufacturing industry,the demand for various automobile parts and components is growing.The increasing market demand urges auto parts manufacturers to innovate their own production technologies.In this paper,the design of multi-station machining system combined with robotic grasping assembly is put forward for the production of automobile generator end caps,which aims to replace the past labor-intensive production methods.Multi-station production line design is a wide range of subject areas involved,this article on the production line system construction,processing equipment selection design,control system design conducted a detailed introduction of the study,the final design of the finished production line experimental processing,put forward The optimization program.In this paper,the process of generator end cap is analyzed first,the specific process route of robot grasping and processing is established,and the processing equipment such as turning,drilling,milling and cleaning are reasonably allocated,and finally,The "island" layout around which robots are mounted while other devices are set up.According to the processing requirements,a suitable robot is selected as the grasping equipment.At the same time,special fixture for the three finishing stations is designed according to the characteristics of robot grasping and processing,which can effectively improve the positioning accuracy and clamping strength of the robot grasping and placing,Special fixtures will be three-position clamping and positioning accuracy to ± 0.008mm.The generator control end multi-station production line control needs analysis and research,will be divided into automatic transport module,robot module,machining center module and the detection module of four parts of the various parts of the control program was analyzed and completed The entire control system PLC points division.Production line system after the completion of the overall system from the transmission system,the station beats and process parameters configuration optimization of the three aspects,the final experimental production of the pilot production,bearing the production of bearing hole diameter accuracy can reach-0.012mm～-0.028mm,Bearing roundness of 0.008mm.
