[0034] The abrasive belt wheel of the abrasive belt wheel grinding device 1 rotates at high speed to achieve external grinding work;

[0035] The slider connecting seat 3 is connected to the floating slide 4 to ensure that the working device can float up and down and be controlled to move in a linear manner.

[0036] In the above-mentioned external grinding device of a wheeled mobile grinding robot, the floating slide 4 includes a guide rail base 9 connected to the robot through a fixed base 8. The fixed base 8 is fixedly connected to the guide rail base 9 to realize the connection between the external component and the robot as a whole. The left and right sides of the guide rail base 9 are respectively provided with a spring center rod 12, and a guide rail 10 is provided in the middle. A compression spring is installed on the outside of the spring center rod 12. One end of the compression spring 5 is fixed to the guide rail base 9, and the other end acts on the spring push plate 6 to apply pressure to the spring push plate 6. The spring push plate 6 is slidably connected to the spring center rod 12, and the slider 11 is installed on the guide rail 10, and can be moved up and down along the guide rail. The top of the slider 11 is fixedly connected to the slider connecting seat 3, and the two can move simultaneously along the guide rail direction.

[0040] The high-pressure nozzle 2 is also included, and the high-pressure nozzle 2 is connected to the grinding wheel so that it is located above the grinding wheel. The high-pressure nozzle 2 includes a high-pressure nozzle 14 and a nozzle fixing nut 13. The high-pressure nozzle 14 is connected to the nozzle fixing nut 13 to fix the high-pressure nozzle 2.
