The working principle is that a workpiece to be polished is placed in the machine table 1, so that the workpiece is placed below the polishing disc 18 and the pressing plate 10.
In the initial state, the pressing plate 10 and the polishing disc 18 are in a suspended state, and the pressing plate 10 is lower than the polishing disc 18.
And starting the electric push rod 2, and driving the supporting plate 3 to move downwards by a telescopic shaft of the electric push rod 2. The supporting plate 3 drives the threaded rod 13 to move downwards through the fixing plate 17 and the fixing frame 12, and the threaded rod 13 drives the polishing disc 18 to move downwards through the moving block 14, the connecting shaft 15 and the polishing motor 16 in sequence. In this process, the supporting plate 3 drives the fixing case 4 to move downward, and the fixing case 4 drives the pressing plate 10 to move downward synchronously.
As the downward movement of the support plate 3 proceeds, the pressing plates 10 on both sides of the polishing motor 16 are brought into contact with the top of the workpiece. Then, under the blocking action of the workpiece, the second rack 9 moves upwards relative to the fixed box 4, and the upward movement of the second rack 9 drives the gear 7 to rotate. The rotation of the gear 7 drives the first racks 8 meshed with the gear to move towards the direction approaching the polishing motor 16 until both the first racks 8 are abutted against the polishing motor 16, and the polishing disc 18 is just in contact with the workpiece. In addition, the spring 5 is compressed in the process of moving upwards relative to the fixed box 4, and the pressure plate 10 can be acted by the elasticity of the spring 5, so that the pressure plate 10 is prevented from sliding.
The electric putter 2 is stopped. The polishing motor 16 is started, and the output shaft of the polishing motor 16 drives the polishing disc 18 to rotate, so that the upper surface of the workpiece is polished.
The output shaft of the motor 11 is controlled to rotate positively, the output shaft of the motor 11 drives the threaded rod 13 to rotate, and the threaded rod 13 rotates to drive the moving block 14 to slide to the right along the central axis of the threaded rod 13. Sliding of the moving block 14 will drive the connecting shaft 15, the grinding motor 16 and the grinding disc 18 to move synchronously.
In the process of sliding the moving block 14 to the right, the polishing motor 16 pushes the first rack 8 on the right to slide synchronously, so as to drive the gear 7 on the right to rotate. The rotation of the right gear 7 drives the right second rack 9 to slide upwards, so as to drive the right pressing plate 10 to slide upwards, and the compression deformation amount of the right spring 5 is gradually increased. In this process, the left platen 10 does not slide, and the workpiece is continuously fixed.
The moving block 14 slides to the right and drives the grinding disc 18 to move to the right, and when the grinding disc 18 moves to the contact position of the right pressing plate 10 and the workpiece, the right pressing plate 10 is located above the grinding disc 18. The grinding wheel 18 does not come into contact with the right side pressure plate 10 during the rightward movement.
The output shaft of the motor 11 is then controlled to rotate reversely, and the output shaft of the motor 11 drives the moving block 14 to slide to the left. In the process of sliding the moving block 14 to the left, the spring 5 on the right pushes the second rack 9 on the right to slide downwards under the elastic action of the spring, so that the pressing plate 10 on the right is driven to slide downwards. In this process, the second rack 9 on the right pushes the gear 7 on the right to rotate reversely, so as to push the first rack 8 on the right to slide towards the left, so that the first rack 8 on the right abuts against the polishing motor 16 and slides towards the left synchronously until the moving block 14 is reset, and the polishing motor 16 is again abutted by the two first racks 8.
The moving block 14 slides to the left and drives the grinding disc 18 to move to the left, and when the grinding disc 18 is separated from the contact position of the right pressing plate 10 and the workpiece, the right pressing plate 10 is located above the grinding disc 18. The sanding plate 18 does not come into contact with the right side platen 10 during movement to the left.
As the sliding of the moving block 14 proceeds to the left, the grinding motor 16 pushes the first rack 8 on the left to slide synchronously, so as to drive the gear 7 on the left to rotate. The rotation of the left gear 7 drives the left second rack 9 to slide upwards, so as to drive the left pressing plate 10 to slide upwards, and the compression deformation amount of the left spring 5 is gradually increased. In this process, the right platen 10 does not slide, and the workpiece is continuously fixed.
The moving block 14 slides leftwards and drives the grinding disc 18 to move leftwards, and when the grinding disc 18 moves to the contact position of the left pressing plate 10 and the workpiece, the left pressing plate 10 is positioned above the grinding disc 18. The sanding plate 18 does not come into contact with the left side platen 10 during movement to the left.
Then, the output shaft of the motor 11 is controlled to rotate in the forward direction, and the output shaft of the motor 11 drives the moving block 14 to slide to the right. In the process of sliding the moving block 14 to the right, the left spring 5 pushes the left second rack 9 to slide downwards under the elastic action of the spring, so that the left pressing plate 10 is driven to slide downwards. In this process, the second rack 9 on the left pushes the gear 7 on the left to rotate reversely, so that the first rack 8 on the left is pushed to slide towards the right, so that the first rack 8 on the left abuts against the polishing motor 16 and slides towards the right synchronously until the moving block 14 is reset, and the polishing motor 16 is again abutted by the two first racks 8.
Thereby completing the comprehensive polishing of the upper surface of the workpiece.
