[0012] In order to more clearly understand the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0013] like Figure 1-3The gear deburring and grinding equipment shown in the figure includes a base plate 1, four pillars 2 are vertically and evenly fixed on the outer edge of the upper end of the base plate 1, and a cross plate 3 is horizontally fixed on the upper end of the pillar 2 to ensure that the position of the cross plate 3 is stable and reliable, and an axle rod 4 is vertically arranged on the upper end of the base plate 1 to limit the position of the gear 6, and a first screw rod 5 is vertically fixed in the middle position of the upper end of the axle rod 4 to tightly sleeve the gear 6 on the axle rod 4, and a locking nut 7 is tightly sleeved on the first screw 5, and the locking nut 7 is tightened to ensure the stability of the position of the gear 6, and the length of the axle rod 4 is lower than the thickness of the gear 6 to ensure that the locking nut 7 can be tightly abutted against the gear 6. An inner gear ring 8 is horizontally arranged on the bottom plate 1 outside the gear 6, and a gap is left between the inner gear ring 8 and the gear 6 to limit the position of the grinding roller 22. Four first hydraulic rod mechanisms 9 are horizontally and evenly fixedly arranged on the bottom plate 1 outside the inner gear ring 8. One end of the first hydraulic rod mechanism 9 faces the shaft rod 4. A clamping block 10 is fixedly arranged on the end of the first hydraulic rod mechanism 9. One end of the clamping block 10 is against the outer wall of the inner gear ring 8. The clamping block 10 moves horizontally under the action of the first hydraulic rod mechanism 9 to limit the position of the inner gear ring 8, which not only ensures the stability of the position of the inner gear ring 8, but also facilitates the adjustment of the gap width between the inner gear ring 8 and the gear 6 to ensure the uniformity of the gap width. A clamping groove 25 is opened in the middle position of the clamping block 10 near the inner gear ring 8. The curvature of the clamping groove 25 is the same as the curvature of the outer wall of the inner gear ring 8, ensuring the reliable connection between the clamping block 10 and the outer wall of the inner gear ring 8. A rubber pad 26 is fixedly disposed in the clamping groove 25 to ensure a tight connection between the clamping block 10 and the outer wall of the inner gear ring 8 . A column 11 is vertically fixed at the lower end of the cross plate 3 and located on the outer side of the inner gear ring 8 to ensure the stability of the position of the column 11. A second hydraulic rod mechanism 12 is horizontally arranged on the side of the column 11 close to the gear 6. A first block 13 is arranged between the column 11 and the second hydraulic rod mechanism 12. One end of the first block 13 is hinged to the second hydraulic rod mechanism 12, which not only ensures the reliable connection between the second hydraulic rod mechanism 12 and the first block 13, but also enables one end of the second hydraulic rod mechanism 12 to rotate horizontally along the first block 13. A clamping block 14 is fixedly arranged on the other end of the first block 13. A connected slide groove 15 and a cavity 16 are vertically opened in the middle position of the column 11 close to the first block 13.

One side of the first block 13 passes through the slide groove 15 and the block 14 is arranged in the cavity 16, which not only ensures the reliable connection between the first block 13 and the column 11 and prevents the separation of the first block 13 and the column 11, but also enables the first block 13 and the block 14 to move smoothly in the vertical direction along the slide groove 15 and the cavity 16, while also avoiding the horizontal deviation of the first block 13. A support plate 17 is horizontally fixedly arranged at the lower end of the column 11 and directly below the first block 13, which reliably supports the third hydraulic rod mechanism 18. The third hydraulic rod mechanism 18 is vertically fixedly arranged at the upper end of the support plate 17. The upper end of the third hydraulic rod mechanism 18 is fixedly connected to the first block 13. The first block 13, the block 14 and the second hydraulic rod The mechanism 12 performs lifting and lowering movements under the action of the third hydraulic rod mechanism 18. A second block 19 is fixedly provided at the end of the second hydraulic rod mechanism 12. A flat plate 20 is horizontally fixedly provided at the lower end of the second block 19. A motor 21 is vertically fixedly provided at the lower end of the flat plate 20 to ensure the stability of the position of the motor 21. The transmission shaft of the motor 21 is connected to one end shaft of the grinding roller 22. The motor 21 drives the grinding roller 22 to rotate. The lower end of the grinding roller 22 is arranged in the gap between the inner gear ring 8 and the gear 6. The width of the gap between the inner gear ring 8 and the gear 6 is the same as the diameter of the grinding roller 22. The grinding roller 22 rotates to grind the teeth at the rim of the gear 6. As the second hydraulic rod mechanism 12 expands and contracts and rotates, the grinding roller 22 moves along the gap to complete the grinding of the burrs at the rim of the gear 6.

[0014] A second screw rod 23 is vertically fixed in the middle position of the lower end of the shaft rod 4, and a threaded hole 24 is opened on the base plate 1. The second screw rod 23 corresponds to the position of the threaded hole 24 and the threads thereof match. The second screw rod 23 is arranged in the threaded hole 24, which not only ensures the reliable connection between the second screw rod 23 and the base plate 1, thereby ensuring the stability of the position of the shaft rod 4, but also enables the shaft rod 4 to be replaced according to the different specifications of the gear 6, thereby ensuring the limiting effect of the shaft rod 4 on the gear 6.

[0015] During operation, the first block 13 and the second hydraulic rod mechanism 12 are driven upward by the third hydraulic rod mechanism 18, the gear 6 is sleeved on the shaft rod 4, the locking nut 7 is tightened, the inner gear ring 8 adjusted in position is clamped by the first hydraulic rod mechanism 9 and the clamping block 10, the first block 13 and the second hydraulic rod mechanism 12 are driven downward by the third hydraulic rod mechanism 18, and the position of the second hydraulic rod mechanism 12 is adjusted at the same time, so that the lower end of the grinding roller 22 is located in the gap between the inner gear ring 8 and the gear 6, the motor 21 is started, the grinding roller 22 rotates, and the teeth at the rim of the gear 6 are ground. With the extension and rotation of the second hydraulic rod mechanism 12, the grinding roller 22 moves along the gap to complete the grinding of the burrs at the rim of the gear 6.
