[0023] like Figure 1 , 2 As shown, specifically, the annular track 1 is in a circular ring structure, with V-shaped ridges on both sides of the annular track 1, and V-groove rollers 8 are provided in pairs at both ends of the track plate 3. Two V-groove rollers 8 are provided at each end of the track plate 3, and are respectively located on the inner and outer sides of the annular track 1, and the V-groove rollers 8 cooperate with the V-shaped ridges. V-shaped ridges are provided on both sides of the circular annular track 1, which cooperate with the V-groove rollers 8, so that the track plate 3 maintains axial stability, and under the stable clamping of the four V-groove rollers 8, the track plate 3 can move around along the annular track 1.

[0024] Furthermore, the track plate 3 is provided with a guide shaft 5, such as Figure 2 As shown, two guide shafts 5 parallel to the diameter direction are arranged on the track plate 3, and a polishing part 6 is slidably arranged on the guide shaft 5. The polishing part 6 moves radially along the annular track 1 under the guidance of the guide shaft 5. The polishing part 6 moves along the direction of the annular track 1 under the control of the guide shaft 5, that is, moves radially along the annular track 1, so as to adapt to the grinding and polishing of polygonal sides of different sizes during its movement. It also includes an elastic component 7, and the elastic component 7 pushes the polishing part 6 to one side of the gear shaft 2. Further, the elastic component 7 is a spring, and two of the springs are provided. The two springs are respectively wound on the two guide shafts 5, and one end of the spring is pressed against the sliding plate 9, and the other end is pressed against the track plate 3.

[0025] In actual production, the number of sides of the polygonal gear shaft 2 can be a triangle, a square, or other shapes. The polishing part 6 is positioned in the circumferential movement direction by using a running track so that the polishing side 16 can face different directions to adapt to the various sides of the polygon. Furthermore, an axial reciprocating drive device is also provided, such as Figure 3 As shown, it is used to drive the gear shaft 2 to reciprocate axially. The reciprocating drive device includes a multi-grip chuck 19. Two multi-grip chucks 19 are coaxially arranged and respectively used to fix the two ends of the gear shaft 2. The two multi-grip chucks 19 are arranged on the processing platform to slide along the axial direction of the gear shaft 2. In actual use, a reciprocating track 21 is arranged on the processing platform. The reciprocating track 21 is arranged along the axial direction of the guide shaft 5. The reciprocating slider 20 slides and moves thereon, so that the multi-grip chuck 19 can slide along the axial direction. During processing, the polygonal non-circular gear shaft 2 is clamped and positioned by the two multi-grip chucks 19, and a cylinder can be arranged on one end of the multi-grip chuck 19 to perform axial reciprocating drive, so that the polygonal cross-section part of the gear shaft 2 repeatedly passes through the annular track 1, and then cooperates with the polishing part 6 to grind and polish each side of the gear shaft 2, thereby completing the processing of the gear shaft 2. Embodiment 1:

[0026] When polishing a non-circular gear shaft 2 with a square cross section, as Figure 1 , 2 As shown, specifically, the polishing part 6 includes a sliding plate 9, on which a linear bearing 10 is provided, and the linear bearing 10 is slidably connected to the guide shaft 5. The sliding plate 9 is slidably connected via the linear bearing 10, so that the stability and accuracy of its movement can be maintained. Under the push of the elastic component 7, the polishing part 6 can maintain pressure on the planar side of the gear shaft 2, thereby realizing the polishing operation.

[0027] The sliding plate 9 is also provided with a driving pulley 11, a driven pulley 12, a tensioning pulley 13, and a tensioning spring 14. One side of the sliding plate 9 is triangular in shape, and the driving pulley 11, the driven pulley 12, and the tensioning pulley 13 are rotatably arranged at each corner position of the triangle. The driving pulley 11, the driven pulley 12, and the tensioning pulley 13 are provided with a polishing belt 15 on the outer sleeve. The output end of the driving motor 17 drives the driving pulley 11 to rotate, so that the polishing belt 15 runs at a high speed, and polishing is achieved when it approaches the side of the gear shaft 2. In this embodiment, Figure 1 , 2 As shown, two groups of track plates 3 are provided on the annular track 1 in a sliding connection, and the two groups of track plates 3 are arranged opposite to each other. The two groups of track plates 3 are fixedly connected by two guide shafts 5, and the two guide shafts 5 are parallel to the diameter of the annular track 1. Two polishing parts 6 are provided in a mirror image between the two groups of track plates 3, and the polishing sides 16 of the two polishing parts 6 are arranged opposite to each other, and the two polishing sides 16 are parallel to each other. When in use, the two polishing parts 6 can be made close to each other at the same time and polish the two opposite sides of the square cross-section at the same time, so that symmetrical polishing can be achieved. When the two opposite sides are polished, the two groups of polishing parts 6 are moved open, the locking bolts 4 are unlocked, and the track plate 3 is rotated so that the polishing side 16 faces the other two sides, and then the locking bolts 4 are used to position it, and then the polishing operation can be performed again.

[0028] like Figure 2 As shown, the triangular polishing belt 15 is parallel to the side of the gear shaft 2 on one side close to the gear shaft 2, and this side is the polishing side 16, and the other two sides are the return sides. The sliding plate 9 is also provided with a driving motor 17, and the inner side of the polishing side is provided with a flat pad 18. When the polishing belt 15 is running, the belt continuously runs to the polishing side 16, and the flatness of the grinding and polishing can be improved through the support of the flat pad 18. Embodiment 2:

[0029] The structure of this embodiment is substantially the same as that of the above-mentioned embodiment, except that this embodiment is suitable for grinding the base polygonal gear shaft 2, such as Figure 4 As shown, specifically, a group of track plates 3 are slidably connected on the annular track 1, and two guide shafts 5 parallel to the diameter are provided on the track plate 3, and a group of polishing parts 6 are slidably provided on the two guide shafts 5. In this embodiment, a triangular cross section is taken as an example. Before processing, the track plate 3 is moved and the polishing side 16 is made parallel to one side of the gear shaft 2, and then positioning is performed. In this embodiment, the first embodiment is improved, and one polishing part 6 is removed, so that each annular track 1 is provided with a polishing part 6, and one side of the gear shaft 2 is polished and polished each time in cooperation with the axial reciprocating drive device, and then the position of the track plate 3 is adjusted, and the polishing side 16 faces the other side, and then the polishing operation is performed again.
