Problems solved by technology
[0003] Many existing flexible mechanical polishing heads can only achieve one-way floating during the polishing process, or the normal floating force is uncontrollable, which cannot meet the required requirements in many occasions
The flexible abrasive belt polishing head is mainly used for the surface of large workpieces, and the surface of the workpiece needs to be relatively smooth. The flexible abrasive belt polishing head is installed at the end of the robot, and the robot cannot move 360 degrees, which brings trouble to the robot programming. It cannot polish small grooves

The invention discloses a flexible polishing device for robot polishing. A proper flange is selected at the tail end of a machine hand to be connected to a base flange of the polishing device, and thedevice is fixed at the tail end of the machine hand; according to the surface needing to be polished, a proper tool chuck is selected to fix a polishing head on a rotating shaft of a spindle motor; according to the surface needing to be polished, reasonable air pressure is provided for a thin air cylinder so as to meet the control of the required polishing force; and an operation program of the robot is planned, so that the polishing task on the surface of a workpiece is completed. By the adoption of the robot flexible polishing device, when the surface polishing is carried out on the workpiece, the polishing force can be flexibly controlled, rigid contact between the polishing head and the workpiece is avoided, and the complexity of robot control is reduced.
Description
technical field [0001] The invention relates to a flexible polishing device, which is mainly used for the polishing of molds, and the device is mainly used for the flexible polishing of robot polishing. Background technique [0002] Robot polishing refers to the use of robots instead of manual labor to complete the corresponding work of polishing in order to obtain the required surface roughness of the workpiece. In the current polishing of automobile abrasive tools, most enterprises still use manual polishing, which is time-consuming and increases the cost of mold manufacturing. With the development of robot technology, people are trying to use robots to replace manual polishing of abrasive tools, so the research on polishing tools is urgent. At present, the equipment used for robot polishing mainly includes flexible mechanical polishing heads, flexible abrasive belt polishing heads and flexible airbag polishing heads. [0003] Many existing flexible mechanical polishing ...
