When the first motor 305 is started, the first motor 305 drives the first threaded rod 304 to rotate, thereby moving the mounting frame 306 along the groove to move the position of the water hood 309 in the left - right direction. Then, when the second motor 312 is started, the worm 310 can be rotated. The rotation of the worm 310 can cause the worm gear 311 to rotate. The worm gear 311 drives the rotating rod 307 to rotate. The fixing blocks 308 rotate with the rotating rod 307, thereby rotating the water hood 309 to adjust the spraying angle of the water hood 309 to ensure that the water flow accurately reaches the hottest grinding area and improve the cooling efficiency.

[0025] As Figure 1 , 4As shown, the clamping assembly includes telescopic push rods one 201 arranged at the left and right ends of the mounting plate 103. The telescopic ends of the telescopic push rods one 201 are both connected with clamping frames 202. The upper ends of the clamping frames 202 are all connected through adjusting screws 203. The bottom ends of the adjusting screws 203 are rotatably connected with clamping plates 204. The clamping plates 204 are slidably connected with the clamping frames 202.

The output end of the fourth motor 211 is connected with a grinding piece 212 through a coupling.

[0027] As Figure 1 , 4 As shown, a baffle 106 is arranged at the rear end of the groove. The baffle 106 is fixedly connected with the bottom frame 101. The arranged baffle 106 can prevent the debris generated during the grinding process from flowing into the groove along with the waste liquid, affecting the transmission effect of the first threaded rod 304 on the mounting frame 306.

[0028] During use, place the automobile seat frame to be ground in the middle of the mounting plate 103. Then start the telescopic push rod one 201 to make the two clamping frames 202 move towards each other. When the two clamping frames 202 move to appropriate positions, place the seat frame between the two clamping members. Then rotate the handwheel 205 to rotate the adjusting screw 203. By rotating the adjusting screw 203, make the clamping plate 204 abut against the seat frame, so as to clamp and position it. Then start the third motor 207 to make the second threaded rod 206 rotate. The rotation of the second threaded rod 206 can make the support plate 208 move along the chute. After the support plate 208 drives the telescopic push rod two 209 to move to an appropriate position, start the telescopic push rod two 209 to move downward to an appropriate position. Then start the fourth motor 211 to drive the grinding piece 212 to rotate, so as to grind the automobile seat frame.

[0029] During the grinding process, a large amount of heat is generated in the automotive seat frame. By setting up the water tank 301, the cooling water sprayed by the water cover 309 can directly act on the grinding area to absorb heat and prevent the workpiece from deforming due to overheating. At the same time, start the first motor 305. The first motor 305 drives the first threaded rod 304 to rotate, thereby causing the mounting bracket 306 to move along the groove so as to move the position of the water cover 309 in the left-right direction. Then, start the second motor 312 to make the worm 310 rotate. The rotation of the worm 310 causes the worm gear 311 to rotate. The worm gear 311 drives the rotating rod 307 to rotate, and the fixed block 308 rotates with the rotating rod 307, thereby causing the water cover 309 to rotate so as to adjust the spraying angle of the water cover 309 to ensure that the water flow accurately reaches the hottest grinding area and improve the cooling efficiency.

[0030] According to another embodiment of the present invention, as Figure 1 shown, a clamping pad 213 is provided on the side wall of the clamping plate 204.
