[0041] The wiring diagrams of the controller 2, electric push rod 12, electric push rod 2 51, motor 1 43, motor 2 71, motor 3 61, motor 4 92 and column-type tension / compression pressure sensor 10 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the wiring diagrams of the controller 2, electric push rod 12, electric push rod 2 51, motor 1 43, motor 2 71, motor 3 61, motor 4 92 and column-type tension / compression pressure sensor 10 will not be explained in detail.

[0042] The working principle is as follows: First, controller 2 controls motor 3 61 to start. Motor 3 61 drives the bidirectional lead screw 62 to rotate. The bidirectional lead screw 62 drives slider 2 63 to slide. Slider 2 63 drives U-shaped plate 64, limiting component 5, rotating component 9, etc. to move, so that the distance between the two U-shaped plates 64 matches the rigid shaft 8. At this time, control motor 3 61 to turn off and place the rigid shaft 8 on the two U-shaped plates 64, so that the central shafts at both ends of the rigid shaft 8 are respectively between the corresponding pair of rotating rollers 1 65. Then, controller 2 controls electric push rod 2 51 to start. The telescopic rod of electric push rod 2 51 extends and drives U-shaped clamping plate 54 to move downward. U-shaped clamping plate 54 drives circular guide rod 2 52 to move along linear bearing 53. At the same time, U-shaped clamping plate 54 drives motor 4 92 and rotating roller 2 91 to move downward, so that the two sets of rotating rollers 2 91 and rotating roller 1 65 limit the rigid shaft 8. At this time, control electric push rod 2 51 to turn off, realizing the function of limiting rigid shafts of different lengths and diameters.

[0043] Then, controller 2 controls the electric push rod 12 to start. The electric push rod 12 drives the lead screw groove 13 to move through the column-type tension and compression pressure sensor 10. The lead screw groove 13 drives the circular guide rod 11 to move along the circular hole (not labeled in the figure) provided on the L-shaped support 3. At the same time, the lead screw groove 13 drives the grinding assembly 7 to move, so that the grinding roller 72 is close to the hard shaft 8. At this time, the column-type tension and compression pressure sensor 10 senses the pressure and feeds back a signal to controller 2. When the grinding roller 72 is pressed tightly against the hard shaft 8, controller 2 controls the electric push rod 12 to close, which can prevent subsequent grinding. Roller 72 performs over-grinding on the hard shaft 8. Then, controller 2 controls motor 4 92 to start, which drives rotating roller 2 91 to rotate, causing the hard shaft 8 to rotate. At the same time, controller 2 controls motor 2 71 to start, which drives grinding roller 72 to rotate. Simultaneously, controller 2 controls motor 1 43 to start, causing motor 1 43 to rotate forward and backward. Motor 1 43 drives lead screw 42 to rotate back and forth. Lead screw 42 drives grinding assembly 7 to move back and forth through slider 1 41, so that grinding roller 72 grinds the rotating hard shaft 8, thus completing the polishing of hard shaft 8.

[0044] Compared with related technologies, this utility model has the following beneficial effects: By adjusting component 2 6, the distance between the two U-shaped plates 64 is adapted to the hard shaft 8, and the hard shaft 8 is placed on the two U-shaped plates 64, so that the central axes of the two ends of the hard shaft 8 are respectively between the corresponding pair of rotating rollers 1 65. By limiting component 5, the two sets of rotating rollers 2 91 and rotating rollers 1 65 limit the hard shaft 8. By adjusting component 1, the polishing roller 72 is pressed against the hard shaft 8, which can prevent the subsequent polishing roller 72 from excessively polishing the hard shaft 8. By rotating component 9, the hard shaft 8 is rotated, and at the same time, by polishing component 7, the polishing roller 72 is rotated. By moving component 4, the polishing roller 72 is controlled to polish the rotating hard shaft 8, thus completing the polishing of the hard shaft 8.

[0045] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
