Second transverse plates 41 are provided at the front and rear ends of the supporting platform 4. Screw holes 320 are provided on the edges of the second transverse plates 41, and the second transverse plates 41 can also be fixed in position by installing screws.

[0030] The first cross rail 1 and the second cross rail 2 are both provided with a sliding block 5, which passes through the first cross rail 1 and the second cross rail 2 and is slidably connected to the first cross rail 1 and the second cross rail 2. The sliding block 5 is provided with a socket 50, and a first square plate 6 is provided on the upper surface of the sliding block 5. The first square plate 6 is fixedly connected to the upper surface of the sliding block 5. When the sliding block 5 moves, the first square plate 6 and the second square plate 12 will also move.

[0031] A counterweight 60 is provided at the left end of the first square plate 6, and the counterweight 60 includes a connecting plate 601 and a pull rod 602. The counterweight 60 makes the first square plate 6 more stable when moving left and right, and the first square plate 6 will not shake when moving. The pull rod 602 allows the staff to manually pull the first square plate 6. When detecting the operating status of the first square plate 6, there is no need to start the driver 8. By manually pulling it a few times, it can be observed whether the operating condition of the first square plate 6 is good. A first connecting shaft 7 is provided at the right end of the first square plate 6.

[0032] A driver 8 is disposed on the support platform 4 , and a rotating plate 9 is disposed on the output shaft of the driver 8 . The rotating plate 9 is a diamond-shaped structure, and a second connecting shaft 10 and a third connecting shaft 11 are respectively disposed on the farthest two ends thereof.

A fourth connecting shaft 13 is provided on the upper surface of the second square plate 12. The fourth connecting shaft 13 is located at the right end of the second square plate 12.

[0034] A first power rod 14 is provided between the first connecting shaft 7 and the second connecting shaft 10 , and a second power rod 15 is provided between the fourth connecting shaft 13 and the third connecting shaft 11 .

[0035] Both ends of the first power rod 14 and the second power rod 15 are rotatably connected to the connecting shaft. The length of the second power rod 15 is greater than that of the first power rod 14, so that the rotating plate 9 can more easily drive the second square plate 12 to move while driving the square plate to move.

[0036] The shaft body 16 is a block structure with a notch 160. The shaft body 16 is provided with a through hole 161 communicating with each other on the left and right sides, and the notch 160 is in an arc shape.

[0037] A connecting piece 17 is provided on the shaft body 16, and the connecting piece 17 is composed of an L-shaped insertion rod 171 and an L-shaped buckle plate 172. The insertion rod 171 includes a first rod 1711 and a second rod 1712. The first rod 1711 matches the socket 50 of the sliding block 5, and the second rod 1712 matches the through hole 161 on the shaft body 16. A recessed hole 1710 is provided at the right end of the second rod 1712. When the shaft body 16 needs to be installed on the sliding block 5, the first rod 1711 is inserted into the socket 50 of the sliding block 5, and the second rod 1712 is inserted into the through hole 161 of the shaft body 16. The right end of the second rod 1712 extends to the right side of the shaft body 16.

[0038] The buckle plate 172 includes a first plate 1721 and a second plate 1722. The thickness of the first plate 1721 is consistent with the thickness of the recessed hole 1710. A pin 173 is provided on the outer side surface of the second plate 1722. The connecting member 17 is symmetrically provided with two groups about the horizontal center line of the shaft body 16. After the insertion rod 171 is installed, the buckle plate 172 is installed so that the first plate 1721 of the buckle plate 172 is located in the recessed hole 1710 of the insertion rod 171. The position of the buckle plate 172 is fixed with the pin 173. In this way, the buckle plate 172 limits the position of the insertion rod 171, so that the connecting member 17 plays the role of connecting the shaft body 16 and the sliding block 5 together. At this time, the notch 160 of the shaft body 16 is located on the first cross rail 1 or the second cross rail 2, and the raised particles on the notch 160 are polished.

[0039] Working principle: connect the shaft body 16 to be polished with the sliding block 5, start the driver 8, the driver 8 includes a motor, and the driver 8 rotates 45 degrees counterclockwise and then 45 degrees clockwise, so that the two ends of the rotating plate 9 can pull the power rod to move. During the process of the driver 8 rotating 45 degrees counterclockwise, the first power rod 14 pulls the first square plate 6 to move in the direction of the supporting platform 4, and the second power rod 15 pulls the second square plate 12 to move in the direction of the supporting platform 4. At this time, the sliding blocks 5 fixedly connected to the square plates are consistent with the movement direction of the square plates. During the sliding process of the sliding block 5, the notch 160 of the shaft body 16 contacts the first cross rail 1 or the second cross rail 2 and is continuously polished.

[0040] When the driver 8 rotates clockwise for another 45 degrees, the rotating plate 9 is reset. At this time, the first square plate 6 and the second square plate 12 drive the sliding block 5 to move to both sides of the first horizontal rail 1 and the second horizontal rail 2. During the left and right movement of the sliding block 5, the shaft body 16 is driven to move left and right on the first horizontal rail 1 or the second horizontal rail 2, and the notch 160 on the shaft body 16 is polished. After the polishing is completed, the connecting piece 17 is removed to separate the shaft body 16 from the sliding block 5, and the polished shaft body 16 can be taken away. This is the working principle of the shaft polishing device.
