An extended cantilever 26 is horizontally arranged on the upper side of the rotating sleeve 25. One end of the extended cantilever 26 away from the rotating sleeve 25 is rotatably connected to a vertically arranged tension rod 18. The upper end of the main shaft 24 is fixedly connected to the main shaft 24. A driving pulley 27 is connected, and the driving pulley 27 is connected to a driven pulley 28 through a synchronous belt 29.

A grinding head 31 is arranged above the sliding seat 30, so that the grinding head 31 is driven to move horizontally by the synchronous belt 29, and a reversing component 32 is arranged above the sliding seat 30. The reversing component 32 can make the direction of the grinding head 31 parallel or perpendicular to the extended cantilever 26; The clamping mechanism 3 includes a side plate 6 vertically arranged in the middle of the rear side of the grinding platform 1, the upper end of the side plate 6 is fixedly connected to a cantilever beam 7 arranged in a front-to-back direction, a pressing plate 8 is arranged at the lower front side of the cantilever beam 7, and the pressing plate 8 can move up and down, so as to fix the circular plate 4 and the straight plate 5 through the pressing plate 8, and the end of the main shaft 24 is provided with an auxiliary support assembly 36 that cooperates with the pressing plate 8; After the rotating sleeve 25 is fixed to the main shaft 24 by rotating the locking assembly 23, the rotating sleeve 25 and the main shaft 24 rotate synchronously, so that the extended cantilever 26 rotates synchronously with the main shaft 24, that is, the grinding head 31 rotates along the center of the main shaft 24, so that the grinding head 31 grinds the side of the circular plate 4. After the rotating sleeve 25 is fixed to the grinding platform 1 by rotating the locking assembly 23, the rotating sleeve 25 stops rotating. At this time, when the main shaft 24 rotates, the synchronous belt 29 of the main shaft 24 drives the sliding seat 30 to slide along the extended cantilever 26, so that the grinding head 31 grinds the side of the flat plate 5. In order to better deflect the extended cantilever 26, a roller is set on the lower surface of the extended cantilever 26, and the roller can roll on the upper surface of the grinding platform 1, thereby improving the stability of the extended cantilever 26.

[0025] In one case of the present embodiment, the rotation locking assembly 23 includes left and right fixing plates 20 arranged at the lower end of the rotating sleeve 25, the lower end of the fixing plate 20 is threadedly connected with a tightening screw 21 arranged in left and right directions, and a limit seat 22 is arranged on the left and right sides of the rotating sleeve 25, the upper end of the limit seat 22 is fixedly connected to the lower surface of the grinding platform 1, and tightening blocks 19 are arranged on the left and right ends of the tightening screw 21.

Therefore, the grinding motor 43 causes the grinding head 31 to rotate at a high speed through gear transmission. In addition, limit holes 39 are provided on the rear side and right side of the sliding seat 30, and an L-shaped limit frame 37 is provided at the lower end of the deflection rod 41, and a horizontally arranged limit rod 38 is slidably connected to the limit frame 37. When the grinding head 31 is set to the left, the limit rod 38 can be inserted into the limit hole 39 at the rear end of the sliding seat 30 to achieve the effect of direction limiting.

Therefore, when there is no external force, the limit rod 38 will always remain inserted into the limit hole 39, thereby improving the stability of direction locking.

[0028] In one case of the present embodiment, a rotating disk 13 is provided at the lower front part of the cantilever beam 7, and fixed seats 12 are provided on both sides of the rotating disk 13. The fixed seats 12 can rotate along the rotating disk 13, and a telescopic slide rod 11 is vertically provided on the lower surface of the fixed seat 12. The extension rod of the telescopic slide rod 11 extends downward, and the extension rod of the telescopic slide rod 11 is fixedly connected to the upper surface of the pressing plate 8, and a tension spring is provided inside the telescopic slide rod 11, and the tension spring pulls the extension rod of the telescopic slide rod 11 upward.

When the piston rod of the clamping cylinder 10 is extended, the pressure head 9 will contact the pressure plate 8, and the pressure head 9 will push the pressure plate 8 to move downward, that is to say, the cooperation of the clamping cylinder 10 and the telescopic slide rod 11 can control the up and down movement of the pressure plate 8. The auxiliary support assembly 36 includes a deflection plate 33 rotatably connected to the upper end of the main shaft 24, the rear end of the deflection plate 33 is rotatably connected to the rotating seat 34, the rotating seat 34 and the center of the rotating disk 13 are arranged in a colinear manner, and the end of the support plate 35 is fixedly connected to the upper part of the rotating seat 34.

At this time, the pressure plate 8 is rotated to the left and right state, and the straight plate 5 is placed on the support plate 35. At this time, the pressure plate 8 moves downward to fix the straight plate 5.

[0029] During the implementation of this embodiment, a supporting device is arranged below the grinding platform 1 so that the grinding platform 1 can maintain a horizontal state to grind the plate.

[0030] The circular side is polished, the piston rod of the clamping cylinder 10 is retracted, the pressure head 9 is disengaged from the pressure plate 8, and the pressure plate 8 is rotated to the front-to-back setting state, the deflection plate 33 is rotated to the backward state, and the support plate 35 is rotated to the forward state.

The main shaft 24 moves the sliding seat 30 to the left through the synchronous belt 29, and the grinding head 31 is close to the side of the circular plate 4. At this time, the screw rod 21 is rotated in the opposite direction to tighten the rotating sleeve 25 and the main shaft 24. The grinding motor 43 is started, and the grinding head 31 starts to rotate. The rotating drive motor 15 is started again, and the rotating sleeve 25 rotates with the main shaft 24.

At this time, the deflection plate 33 and the support plate 35 are in an L-shaped state, the grinding head 31 is rotated to a backward state, and the straight plate 5 is placed on the support plate 35 facing left and right. The grinding head 31 is pressed and slightly retracted into the deflection seat 42, and the clamping cylinder 10 is started in reverse.
