Further, the controller 201 controls the operation of the cleaning motor 805, thereby driving the cleaning disc 801 to rotate, and then driving the cleaning wire 803 to clean the burrs at any position on the top of the support plate 2.

[0042] The working process of the present invention is as follows: When using this device and needing to grind the side wall of the casting, the staff controls the operation of multiple rotary plate motors 402 through the controller 201, thereby driving the rotary plate reversing block 406 to rotate, thereby driving the rotary plate 4 to rotate, thereby driving multiple clamping rods 5 to rotate along the rotary plate motor 402 at one end thereof, so that multiple clamping wheels 511 approach each other. Further, the staff clamps the entire device to the inner and outer sides of the lower casting 1 and the upper casting 101. Further, the controller 201 controls the operation of multiple clamping rod movers 502, thereby driving multiple clamping rods 5 to extend, and further driving the movement of multiple clamping wheel stabilizer plates 505, so that multiple clamping wheels 511 approach each other, so that one group of the clamping wheels 511 is in close contact with the inner wall of the lower casting 1, and at the same time, the group of clamping wheels 511 opposite thereto is in close contact with the outer wall of the lower casting 1. At this time, due to the action of the clamping wheel positioning rod 506 and the clamping wheel spring 507, the entire device can be relatively fixed. Further, the controller 201 controls the operation of multiple stabilizer rod movers 301, thereby driving multiple stabilizer rods 3 to extend, so that the multiple universal wheels 303 at the right end are in close contact with the inner walls of the lower casting 1 and the upper casting 101, so that the entire device is relatively fixed. Further, the controller 201 controls the operation of the grinding camera 802 and the moving motor 603, thereby driving the moving gear 604 to rotate, and driving the moving gear 604 to move along the moving rack 605. Further, the controller 201 controls the operation of the moving rod controller 601, thereby driving the moving rod 6 to extend and retract, and driving the approaching block 701 to move up and down.

Thus, the three cooperate with each other to enable the reversing block 703 to reach any position on the top of the support plate 2, so that any position on the top of the support plate 2 can be ground. Further, the controller 201 controls the operation of the cleaning motor 805, thereby driving the cleaning disc 801 to rotate, and driving the cleaning wire 803 to clean the burrs at any position on the top of the support plate 2. At the same time, the controller 201 drives the reversing plate 705 to rotate by controlling the reversing block motor 704, so that the cleaning disc 801 can be reversed, so that the cleaning wire 803 can clean castings of different shapes. When the cleaning is completed, the controller 201 controls the operation of the conversion motor 807, thereby driving the positioning plate 806 to rotate, and driving the grinding disc 8 and the cleaning disc 801 to be reversed. Further, the controller 201 controls the operation of the grinding motor 804 to start the grinding work.At this time, the controller 201 controls the water pump 905 and the solenoid valve 904 to cooperate to convey the clear water in the water tank 902 to the nozzle 9 through the water delivery pipe 901, and further spray it onto the surface of the grinding disc 8 through the nozzle 9, so as to reduce the temperature of the grinding disc 8. At this time, due to the action of the sealing screw 908, the sealing sub-plate 909 and the sealing nut 910, the sealing plate 907 and the water tank opening 906 can be made to be in close contact, so as to prevent the clear water from flowing out of the water tank opening 906. Further, the controller 201 controls the moving rod controller 601, the moving gear 604, the approaching rod controller 702 and the reversing block motor 704 so that the grinding disc 8 can reach any position on the top of the support plate 2, so as to grind any position on the top of the support plate 2, so as to complete the cleaning and grinding work of the casting on the top of the support plate 2. When the grinding of the top area of the support plate 2 is completed, the controller 201 controls the clamping wheel motor 510 to work, so as to drive the clamping wheel main gear 509 to rotate, so as to drive the clamping wheel rotating sub-gear 508 to rotate, so as to drive the clamping wheel 511 to rotate, so that the inner clamping wheel 511 on the right end rotates along the inner walls of the lower casting 1 and the upper casting 101, and at the same time, the outer clamping wheel 511 on the right end rotates along the outer walls of the lower casting 1 and the upper casting 101, so that the whole device rotates to the next area, so as to complete the grinding work of the edge of the casting. Similarly, the whole device can move along the connecting plate 103, so as to grind the side wall of the connecting plate 103. If it is necessary to grind the inner wall of the casting, the controller 201 controls the rotating plate motor 402 to work in the reverse direction, so as to make the rotating plate 4 reverse, so as to drive a plurality of the clamping wheels 511 to move away from each other. Further, the staff puts the whole device into the lower casting 1 and the upper casting 101. Further, the controller 201 controls the cooperation of a plurality of clamping rod movers 502 and a plurality of stabilizing rod movers 301 so that a plurality of clamping rods 5 and a plurality of stabilizing rods 3 extend, so that a plurality of clamping wheels 511 and a plurality of universal wheels 303 are in close contact with the inner walls of the upper casting 101 and the lower casting 1. Further, the controller 201 controls the lighting switch 206 and the moving camera 203 to work, so as to drive the lighting lamp 204 to turn on and monitor the movement of the whole device through the lighting lamp 204 at the same time. Furthermore, the controller 201 controls the whole device to start the grinding work of a toroidal surface. When the grinding work of a toroidal surface is completed, the controller 201 controls a plurality of reversing motors 403 to work, so as to drive a plurality of reversing main gears 404 to rotate, so as to drive a plurality of reversing sub-gears 405 to rotate, so as to drive a plurality of clamping rod rotating shafts 503 to rotate, so as to drive a plurality of clamping rods 5 to rotate, so as to drive multiple groups of the clamping wheels 511 to reverse.Furthermore, by controlling the clamping wheel motor 510, the entire device can be horizontally moved along the inner walls of the lower casting 1 and the upper casting 101, so that it can be moved to the next toroidal surface, thereby completing the grinding work on the inner walls of the upper casting 101 and the lower casting 1.
