Problems solved by technology

Among various grinding devices, there are many grinding tools with floating characteristics, most of which adopt the way of directly connecting the output of the pneumatic or electric spindle to the grinding tools. , due to the limitation of the accessibility of the robot's joint motion and the structural reasons of the floating device, some situations where the surface to be processed cannot be reached or the floating range is limited
Moreover, most radial floating grinding tools are mostly used in the field of deburring, and are rarely used in other grinding applications.

Abstract

The invention discloses a radial floating grinding device for an industrial robot. The radial floating grinding device comprises a flange installation plate, a grinding motor, a universal joint assembly and a radial floating device; the grinding motor and the radial floating device are arranged on the flange installation plate, the output shaft of the grinding motor is connected with a connectingrod through the universal joint assembly, the connecting rod penetrates through the radial floating device, the other end of the connecting rod is connected with a grinding tool, the connecting rod transmits the pressure on the grinding tool to the radial floating device through the deviation state of the connecting rod, and the radial floating adjustment is produced by the radial floating devicethrough the connecting rod under the action of the universal joint assembly. According to the radial floating grinding device, a transmission connection mode of universal joint transmission and a radial joint bearing is adopted, the air intake of each radial distribution cylinder in the device is controlled by an electromagnetic valve, combined with the floating characteristics of the radial floating device, various changes generated by the grinding wheel posture when the grinding plane changes can be automatically adapted, and thus the characteristic of constant force floating in any direction of a grinding wheel is achieved.

Description

technical field [0001] The invention relates to the field of automatic grinding of industrial robots, in particular to a radial floating grinding device for industrial robots and a method thereof. Background technique [0002] Robot grinding is an extremely wide application field of industrial robots. Grinding robots replace manual grinding and polishing operations, which can effectively reduce the damage to the human body caused by dust generated by grinding operations. At the same time, they have good grinding consistency and high grinding efficiency. work advantages. Among various grinding devices, there are many grinding tools with floating characteristics, most of which adopt the way of directly connecting the output of the pneumatic or electric spindle to the grinding tools. , Due to the limitation of the accessibility of the robot joint motion and the structural reasons of the floating device, some surfaces to be processed cannot be reached or the floating range is l...
