Design Of Cutting Truss Robot For Grinding Production Line Of Railway Freight Car Bearing

In the development of industrial automation,robots are more and more widely used in industrial production filed because of its unique advantages.It can replace human beings to complete a lot of dangerous and repetitive physical labor works,so as to free human beings from labor works.The appearance of robot is a milestone of the research process of automation.It indicates that man is no longer limited to the research of a single subject of automation,but integrate the mechanical technology,intelligence technology,control technology,sensor technology and computer technology.With the development of science and technology,in all the fields it is improving the degree of automation in the manufacturing process.The birth of industrial robots has played a crucial role in improving the intelligence,digitization and automation of bearing manufacturing enterprises.CNC machine tools cooperate with the production line mode of robots to rapidly occupy the bearing manufacturing industry,which can widely cover all the processes of bearing manufacturing process.It is not only realized the goal of cost reduction in the manufacturing process but also increased the efficiency in manufacturing industry,and steadily;guaranteed of product quality.Based on the understanding of the development of the grinding production line and gantry robot at present and the current situation at our country and abroad,and the in-depth analysis of the grinding process characteristics of railway cargo bearings and the overall scheme of the grinding production line,the structural dimension of the grinding production line is designed,with the emphasis on the design of the specific dimension parameters of each part of the robot,as well as the relevant parts.The 3D model of gantry robot is established by Solid Works 3D design software,and the main parts of the robot,such as the main structure,manipulator,mobile system,are fully analyzed and optimized.According to the automatic loading and unloading action plan of gantry robot,the control system scheme of gantry manipulator is designed.By analyzing the control system combination mode of gantry production line and CNC machine tool,the control mode,the hardware composition of the system and the specific flow path of design,installation and debugging are designed.Integrated with the grinding production line of railway bearings,the designed loading and unloading gantry robot has been in operation for more than one year.The operation accuracy and reliability of the loading and unloading gantry robot have met the design requirements,met the requirements of the production line,and greatly improved the work efficiency and quality.
