[0023] Among them, the position adjustment mechanism 3 is respectively arranged in the middle part of the sliding frame 2, and the end of the position adjustment mechanism 3 close to the center of the working bin 1 is fixedly connected with the grinding plate 4. The position adjustment mechanism 3 includes a support plate 31, an electric push rod 32 and an adjustment plate 33. The support plate 31 is respectively fixedly connected to the middle part of the relative inner surface of the sliding frame 2, and the middle part of the adjustment plate 33 is rotatably connected to the end of the support plate 31 close to the center of the working bin 1.

The input ends of the electric push rods 32 are electrically connected to the output ends of the PLC controller 15. When the electric push rods 32 are running, the telescopic ends of the upper electric push rods 32 are contracted, and the telescopic ends of the lower electric push rods 32 are extended, so that the adjustment plates 33 are rotated under the action of the laterally adjacent support plates 31, and the rotation of the adjustment plates 33 drives the grinding plate 4 to rotate, thereby realizing the angle adjustment of the grinding plate 4.

[0024] Among them, the spacing adjustment mechanism 5 is arranged inside the working bin 1, and the lower end of the sliding frame 2 is slidably connected to the upper end of the spacing adjustment mechanism 5. The spacing adjustment mechanism 5 includes an adjusting disk 53, a connecting rod 54 and a connecting shaft 55. The connecting shafts 55 are respectively fixedly connected to the lower ends of the sliding frame 2. The center position of the top wall of the working bin 1 is rotatably connected with the adjusting shaft. The adjusting disk 53 is fixedly connected to the upper end of the adjusting shaft. The connecting rod 54 is rotatably connected to the left and right ends of the adjusting disk 53 respectively. The ends of the connecting rod 54 away from the adjusting disk 53 are rotatably connected to the laterally adjacent connecting shafts 55. The spacing adjustment mechanism 5 also includes a motor 51, a worm 52 and a worm wheel 56. The worm wheel 56 is fixedly connected to the lower end of the adjusting shaft. The worm 52 is rotatably connected to the front inner wall of the working bin 1. The worm wheel 56 is meshed with the worm 52. The motor 51 is arranged at the working bin 1. At the front end of the bin 1, the output shaft of the motor 51 is fixedly connected to the front end of the worm 52, and the input end of the motor 51 is electrically connected to the output end of the PLC controller 15. When the motor 51 runs, the output shaft of the motor 51 rotates to drive the worm 52 to rotate, and then drives the worm wheel 56 to rotate. The rotation of the worm wheel 56 drives the adjusting shaft to rotate, and then drives the adjusting disk 53 to rotate. The rotation of the adjusting disk 53 makes the end of the connecting rod 54 close to the adjusting disk 53 rotate around the central axis of the adjusting shaft. At the same time, the end of the connecting rod 54 away from the adjusting plate 53 pulls the vertically adjacent sliding frame 2 through the laterally adjacent connecting shaft 55, so that the sliding frame 2 moves toward the center of the working bin 1 under the guidance of the guide column 13, and then the grinding plate 4 moves toward the center of the working bin 1, thereby realizing the spacing adjustment of the grinding plate 4.

[0025] Among them: the internal rotation of the bracket 6 is connected with a screw rod 7, the middle part of the screw rod 7 is threadedly connected to the rear end of the lifting plate 10, the lower end of the screw rod 7 is fixedly connected to a driven bevel gear, and the rear end of the top wall of the working bin 1 is provided with a motor 2 9, the output shaft of the motor 2 9 is fixedly connected to a driving bevel gear 8, the driving bevel gear 8 is meshedly connected with the driven bevel gear, and the input end of the motor 2 9 is electrically connected to the output end of the PLC controller 15.

[0026] The working principle of the utility model is as follows:

[0027] During work, the personnel first stably place the working chamber 1, the bracket 6 and other mechanisms in the horizontal working area. After the placement is stable, the personnel first place the conical surface of the plug valve to be polished on the upper end of the storage tray 14, and then realize the operation of the motor 2 9 through the PLC controller 15. The output shaft of the motor 2 9 rotates to drive the driving bevel gear 8 to rotate, and then drives the driven bevel gear to rotate, and then drives the screw 7 to rotate, so that the lifting plate 10 moves downward inside the bracket 6. The lifting plate 10 moves downward and drives the positioning plate 12 to move downward through the rotating shaft. The positioning plate 12 cooperates with the storage tray 14 to achieve stable clamping of the plug valve.

[0028] After the clamping is stable, the PLC controller 15 turns off the motor 2 9 and realizes the operation of the electric push rod 32. The telescopic ends of the upper electric push rod 32 are all contracted, and the telescopic ends of the lower electric push rod 32 are all extended, so that the adjustment plates 33 are all rotated under the action of the laterally adjacent support plates 31. The rotation of the adjustment plates 33 drives the grinding plates 4 to rotate, thereby realizing the angle adjustment of the grinding plates 4.

[0029] When the grinding plate 4 moves to the required position, the PLC controller 15 turns off the electric push rod 32, and then the PLC controller 15 realizes the operation of the motor 1 51. The output shaft of the motor 1 51 rotates to drive the worm 52 to rotate, and then drives the worm wheel 56 to rotate. The rotation of the worm wheel 56 drives the adjustment shaft to rotate, and then drives the adjustment disk 53 to rotate. The rotation of the adjustment disk 53 makes the end of the connecting rod 54 close to the adjustment disk 53 rotate around the central axis of the adjustment shaft. At the same time, the end of the connecting rod 54 away from the adjustment plate 53 pulls the vertically adjacent sliding frame 2 through the laterally adjacent connecting shaft 55, so that the sliding frame 2 moves toward the center of the working bin 1 under the guidance of the guide column 13, and then the grinding plates 4 move toward the center of the working bin 1, so that the spacing of the grinding plates 4 can be adjusted.

[0030] When the grinding plate 4 moves to the required position, the PLC controller 15 turns off the motor 1 51 and enables the motor 3 11 to operate. The output shaft of the motor 3 11 rotates to drive the rotating shaft to rotate, and then drives the positioning plate 12 to rotate. The positioning plate 12 cooperates with the placement plate 14 to realize the rotation of the plug valve, thereby realizing the polishing of the conical surface of the plug valve.

[0031] It is worth noting that the electric push rod 32 disclosed in the above embodiment can use SD50 electric push rod, motor 1 51 and motor 2 9 can use 5IK120A-AF motor, motor 3 11 can use LIKO MOTOR57 two-phase stepper motor, PLC controller 15 can use DVP32EH00R3-L programmable controller, and PLC controller 15 controls the operation of electric push rod 32, motor 1 51, motor 2 9 and motor 3 11 using methods commonly used in the prior art.
