Robot intelligent grinding and polishing system for door frame grinding and polishing

Abstract

The invention provides an intelligent grinding and polishing system of a robot for grinding and polishing of vehicle door frames. The grinding and polishing system includes a unit base (600), a vehicle door frame fixture (200), a grinding and polishing robot body (300), a polishing and polishing device and an abrasive paper replacement device (500). The grinding and polishing robot body (300) andthe abrasive paper replacement device (500) are both tightly installed on the unit base (600); the vehicle door frame fixture (200) is fixedly or detachably installed on the unit base (600); the grinding and polishing device is installed on the grinding and polishing robot body (300), and the grinding and polishing robot body (300) can drive the grinding and polishing device to move between the vehicle door frame fixture (200) and the abrasive paper replacement device (500). Through the intelligent grinding and polishing system of the robot, full automation and intelligentization of welding joint polishing of the vehicle door frames can be achieved. By automatically replacing abrasive paper, the use efficiency and automation level of an overall vehicle component production line can be improved, and the labor cost is reduced.

Description

technical field [0001] The invention relates to the field of automation and the field of grinding and polishing equipment, in particular to a robot intelligent grinding and polishing system for grinding and polishing car door frames. Background technique [0002] In the current field of industrial automation, the automation level of auto parts production is gradually improving, and the quality requirements for parts are getting higher and higher. After the robot arc welding of the automobile door frame, the grinding of the weld seam gradually began to change from manual grinding to robot automatic grinding. However, in the current automatic grinding station, the workpiece fixture generally uses welding fixtures, and the grinding tools are mainly pneumatic angle grinders and Pneumatic polisher. The positioning accuracy of the welding fixture cannot meet the requirements of grinding and polishing, and it is difficult to control the grinding process parameters such as grinding...

AI Technical Summary

Problems solved by technology

The positioning accuracy of the welding fixture cannot meet the requirements of grinding and polishing, and it is difficult to control the grinding process parameters such as grinding force and grinding speed during the grinding and polishing process, which makes it difficult to guarantee the grinding quality; because the process parameters are difficult to adjust in real time, the sandpaper is worn out and needs frequent Replace the sandpaper, and intelligently polish 2-3 door frames for each piece of sandpaper; ordinary angle grinder polishing machines cannot automatically replace the sandpaper, and frequent manual replacement of sandpaper is required; ordinary angle grinder polishers cannot achieve displacement compensation, and the grinding trajectory of the robot And the entire clamping and positioning accuracy requirements are very high; there are many types of products in the door production line, and ordinary fixtures cannot meet the diverse needs
