General and waist structure design of welding robot
Abstract
In order to improve the production efficiency and welding quality and meet the demand of practical work, this topic design for welding of the joint type robot. Welding robot is a robot a, is performed automatically mechanical device, by its own power and control ability to realize various functions, which can by control the work, can also be run through pre arrangement of the program. In recent years continue to emerge out of is representative of the robot welding technology, but also forward more high degree of automation and intelligent direction of development, these technologies in production efficiency. The precision of welding operation Sex, adaptability, shows the welding robot technology development trend in the future. Welding as manufacturing industry is closely related to the important mode of production, with the gradual deepening of the development of the modernization of industrial production, is facing unprecedented challenges: in welding quality, production efficiency, the manufacturing cost, product line diversification, batch supply capacity, modern production management, of welding technology and welding production model put forward new requirements. Through multi discipline knowledge comprehensive application, strengthen ability of robot application, according to the work requirements for the robot and the characteristics of the structure, the overall design of the robot, and the waist structure design. Also study and formulate the overall robot and the transmission scheme, reasonable layout of the motor and gear, to determine the levels of transmission parameters, gear, shaft and bearing design calculation and checking. Welding robot can provide stable welding quality, improve work efficiency, reduce the production cost, has been widely used in the industrial field. The robot has good rigidity, high precision, smooth operation, strong adaptability characteristics.
Key words: joint type robot; overall design; waist structure design
