| With the "China made 2025" national strategy,the integration of information technology and manufacturing technology as the core of the intelligent manufacturing model is accelerating the development of which the robot industry more and more attention.With the further development of domestic "steady growth" policy,the pace of industrial economic transformation and upgrading is accelerated,the endogenous driving force of economic development is gradually strengthened,and the industrial structure adjustment is needed urgently and the ecological environment is improved.The application of industrial robots in China is expected to keep Speed growth,robot substitutions have become the trend of the times.In recent years in the grinding industry by artificial grinding caused by frequent accidents,the high degree of environmental benefits,labor costs,the need to further improve product quality and production efficiency and other factors are making the industrial robot on behalf of the automation equipment demand rise rapidly.Grinding robots in foreign countries has already begun to use,in recent years,domestic began to gradually pay attention to and development.At present in the auto parts,bathroom hardware industry,home appliance industry,industrial parts,medical equipment and other industries have a more extensive application.Combined with the development level of belt grinding equipment and the actual demand of production,this paper puts forward the design of constant force grinding technology and the design of grinding robot system structure.First,the characteristics of the abrasive belt grinding technology,the principle of the process and the theoretical model of the abrasive grain removal material are studied.Finally,the grinding wheel of the contact wheel is adopted.Then,the advantages and disadvantages of the two configurations are compared for the rectangular coordinate robot.According to the motion relationship and process requirement of the grinding tool relative to the grinding parts,the structural scheme and layout of the grinding robot system are selected.Then,the technology of constant force control grinding is put forward,In order to realize the strength and stiffness of the grinding robot system,the reliability and rigidity of the grinding robot system are improved,and the overall structure and key components of the grinding robot are statistically analyzed and modal analysis.In this paper,The kinematic equation of the grinding robot system is established by using the knowledge of the homogeneous transformation matrix of the coordinate system.Finally,kinematic simulation analysis is carried out to obtain the kinematic characteristic curve,which verifies the feasibility and the theory of the design scheme.The correctness of the analysis. |
