[0027] Working principle:

[0028] Feeding, limiting and grinding work for plastic side window production:

[0029] When the plastic side window needs to be polished during production, the sliding door installed on the third box body 3 is opened, the plastic side window 10 is placed vertically on the square plate 204, and then the sliding door is closed. Then, the external power supply of the first motor 102 is turned on, and the first motor 102 is started to drive the threaded rod 203 to rotate through the bearing in the third box body 3. The rotation of the threaded rod 203 drives the threaded seat 202 to slide upward in the slideway processed on the inner wall of the third box body 3. The upward sliding of the threaded seat 202 can drive the square plate 204 to move upward, and the upper plastic side window 10 is driven to move upward through the square plate 204 (such as Figure 2), when the middle of the plastic side window 10 moves to between the two vertical plates 11, the second motor 201 stops rotating;

[0030] Then, the power lines of the two first hydraulic cylinders 106 are connected to the control panel at the same time, and the external power supply of the two first hydraulic cylinders 106 is turned on at the same time. The two first hydraulic cylinders 106 are started to drive the vertical plate 11 to move relative to each other (such as Figure 2 ), when the two vertical plates 11 are pressed against the surface of the plastic side window 10 and the two first hydraulic cylinders 106 stop moving, the plastic side window 10 can be limited by such movement, and then the second motor 201 is controlled to reverse and the square plate 204 is reset downward, and then the external power supply of the fourth motor 8 is turned on, and the fourth motor 8 is started to drive the grinding wheel 9 to rotate;

[0031] The external power supply of the second hydraulic cylinder 7 is turned on, and the second hydraulic cylinder 7 starts to drive the fourth motor 8 and the grinding wheel 8 to move downward to grind the surface of the plastic side window 10. When the grinding wheel 8 contacts the surface of the plastic side window 10 for grinding, the external power supply of the third motor 4 is turned on, and the third motor 4 starts to drive the reciprocating screw 5 to rotate through the bearing in the third box body 3. The reciprocating screw 5 rotates to drive the screw nut 6 to slide back and forth in the slideway processed on the inner wall of the third box body 3 (such as Figure 3 ), so that the grinding wheel 9 below is driven to move back and forth left and right through the lead screw nut 6 to grind the rest of the surface of the plastic side window 10. When the surface of the plastic side window 10 is polished, the rest of the surface needs to be polished;

[0032] The second hydraulic cylinder 7 is controlled to drive the lower grinding wheel 9 to reset upward, and then the power lines of the two first motors 102 are connected to the control panel at the same time, and the external power supplies of the two first motors 102 are connected at the same time. The two first motors 102 are started to drive the worm 103 to rotate in the first box body 101 through the bearing. The rotation of the worm 103 can drive the worm wheel 104 to rotate in the first box body 101. The rotation of the worm wheel 104 drives the first hydraulic cylinder 106 to rotate in the first box body 101 through the bearing (such as Figure 4 ), the two first hydraulic cylinders 106 rotate to drive the plastic side window 10 to rotate and change the surface. When the surface of the plastic side window 10 to be polished is parallel to the grinding wheel 9, the two first motors 102 are turned off. The plastic side window 10 can be adjusted by such movement, and then the second hydraulic cylinder 7 is controlled again to drive the grinding wheel 9 to move downward for subsequent grinding work.
