This method requires no manual operation, is convenient and quick, saves time and labor, is safe and reliable, and improves polishing efficiency.

Description

Technical Field

[0001] This invention belongs to the field of gear processing technology, and in particular relates to a grinding device for deburring gears. Background Technology

[0002] Gears are mechanical components with teeth on their rims that continuously mesh to transmit motion and power. During gear production, to ensure reliable gear quality, the machined gears need to be ground to remove surface burrs. Current grinding equipment generally grinds the end faces of the gears, but cannot grind the teeth on the gear rim. Workers must manually hold the grinding equipment and grind each tooth on the gear rim individually, which is cumbersome, time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0003] To address the above problems, this invention provides a grinding device for deburring gears.

[0004] This invention is implemented as follows: A gear deburring and grinding device includes a base plate. Multiple vertically and evenly fixed columns are mounted on the upper outer edge of the base plate. A horizontal plate is fixedly mounted on the upper end of each column to ensure the stability and reliability of the horizontal plate's position. A shaft is vertically mounted on the upper end of the base plate to define the position of the gear. A first screw is vertically fixed at the middle position of the upper end of the shaft to tightly fit the gear onto the shaft. A locking nut is tightly fitted onto the first screw. Tightening the locking nut ensures the stability of the gear's position. Internal gears are horizontally mounted on the base plate outside the gear. The internal gear ring has a gap between it and the gear to limit the position of the grinding roller. Multiple first hydraulic rod mechanisms are horizontally and evenly fixed on the base plate outside the internal gear ring. One end of each first hydraulic rod mechanism faces the shaft, and a clamping block is fixed to the end of each first hydraulic rod mechanism. One end of the clamping block abuts against the outer wall of the internal gear ring. The clamping block moves horizontally under the action of the first hydraulic rod mechanisms, limiting the position of the internal gear ring. This ensures the stability of the internal gear ring's position and facilitates adjustment of the gap width between the internal gear ring and the gear, ensuring a uniform gap width.

[0005] A column is vertically fixed at the lower end of the horizontal plate, located outside the internal gear ring, to ensure the stability of the column's position. A second hydraulic rod mechanism is horizontally arranged on the side of the column near the gear. A first block is arranged between the column and the second hydraulic rod mechanism. One end of the first block is hinged to the second hydraulic rod mechanism, ensuring a reliable connection between the two and allowing one end of the second hydraulic rod mechanism to rotate horizontally along the first block. A locking block is fixedly arranged at the other end of the first block. A vertically connected groove and cavity are vertically formed in the middle of the column near the first block. The width of the groove is smaller than the width of the cavity. The length and width of the locking block are related to the cavity. The first block has the same length and width. One side of the first block passes through a groove, and a locking block is disposed in the cavity. This ensures a reliable connection between the first block and the column, preventing separation, and allows the first block and locking block to move smoothly vertically along the groove and cavity while preventing horizontal displacement of the first block. A support plate is horizontally fixedly installed at the lower end of the column, directly below the first block, to reliably support the third hydraulic rod mechanism. The third hydraulic rod mechanism is vertically fixedly installed at the upper end of the support plate, and its upper end is fixedly connected to the first block. The first block, locking block, and second hydraulic rod mechanism move up and down under the action of the third hydraulic rod mechanism.

[0006] A second block is fixedly mounted at the end of the second hydraulic rod mechanism. A flat plate is horizontally fixedly mounted at the lower end of the second block. A motor is vertically fixedly mounted at the lower end of the flat plate to ensure the stability of the motor position. The drive shaft of the motor is connected to one end of the grinding roller. The motor drives the grinding roller to rotate. The lower end of the grinding roller is positioned in the gap between the internal gear ring and the gear. The width of the gap between the internal gear ring and the gear is the same as the diameter of the grinding roller. As the grinding roller rotates, it grinds the teeth at the rim of the gear. With the extension, retraction, and rotation of the second hydraulic rod mechanism, the grinding roller moves along the gap to complete the grinding of the burrs at the rim of the gear.

[0007] Preferably, a second screw is vertically fixed at the middle position of the lower end of the shaft, and a threaded hole is provided on the base plate. The second screw is positioned corresponding to the threaded hole and the threads are engaged. The second screw is set in the threaded hole, which not only ensures a reliable connection between the second screw and the base plate, thereby ensuring the stability of the shaft position, but also allows the shaft to be replaced according to different gear specifications, ensuring the shaft's limiting effect on the gear.

[0008] Preferably, a clamping groove is provided at the middle position of the clamping block near the internal gear ring, and the curvature of the clamping groove is the same as the curvature of the outer wall of the internal gear ring, so as to ensure a reliable connection between the clamping block and the outer wall of the internal gear ring.

[0009] Preferably, a rubber pad is fixedly provided in the clamping groove to ensure a tight connection between the clamping block and the outer wall of the internal gear ring.

[0010] Preferably, the width of the groove is the same as the width of the first block to prevent the first block from shifting its position in the horizontal direction.

[0011] Preferably, the length of the shaft is less than the thickness of the gear, ensuring that the locking nut can be tightly abutted against the gear.

[0012] The beneficial effects of this invention are as follows: the position of the gear is defined by the shaft, the position of the internal gear ring is defined by the first hydraulic rod mechanism and the clamping block, and the position of the grinding roller is adjusted by the second and third hydraulic rod mechanisms, so that the lower end of the grinding roller is positioned in the gap between the internal gear ring and the gear. When the motor is started, the grinding roller rotates and grinds the teeth at the gear rim. As the second hydraulic rod mechanism extends, retracts, and rotates, the grinding roller moves along the gap, completing the grinding of burrs at the gear rim. No manual operation is required, which is convenient, quick, time-saving, labor-saving, safe, and reliable, and improves grinding efficiency. Attached Figure Description

[0017] To better understand the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0018] like Figs. 1-3The gear deburring and polishing equipment shown includes a base plate 1. Four vertically and evenly fixed columns 2 are fixed on the upper outer edge of the base plate 1. A horizontal plate 3 is fixed on the upper end of each column 2 to ensure the stability and reliability of the horizontal plate 3. A shaft 4 is vertically fixed on the upper end of the base plate 1 to limit the position of a gear 6. A first screw 5 is vertically fixed on the middle of the upper end of the shaft 4 to tightly fit the gear 6 onto the shaft 4. A locking nut 7 is tightly fitted on the first screw 5. Tightening the locking nut 7 ensures the stability of the gear 6. The length of the shaft 4 is less than the thickness of the gear 6 to ensure that the locking nut 7 can be tightly pressed against the gear 6. An internal gear ring 8 is horizontally arranged on the base plate 1 outside the gear 6, with a gap between the internal 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 fixed on the base plate 1 outside the internal gear ring 8. One end of the first hydraulic rod mechanism 9 faces the shaft 4, and a clamping block 10 is fixedly arranged at the end of the first hydraulic rod mechanism 9. One end of the clamping block 10 abuts against the outer wall of the internal 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 internal gear ring 8, which not only ensures the stability of the position of the internal gear ring 8, but also facilitates the adjustment of the gap width between the internal gear ring 8 and the gear 6 to ensure the uniformity of the gap width. A clamping groove 25 is opened in the middle of the side of the clamping block 10 near the internal gear ring 8. The curvature of the clamping groove 25 is the same as the curvature of the outer wall of the internal gear ring 8 to ensure a reliable connection between the clamping block 10 and the outer wall of the internal gear ring 8. A rubber pad 26 is fixedly installed inside the clamping groove 25 to ensure a tight connection between the clamping block 10 and the outer wall of the internal gear ring 8. A column 11 is vertically fixed at the lower end of the horizontal plate 3 and outside the internal gear ring 8 to ensure the stability of the column 11. A second hydraulic rod mechanism 12 is horizontally arranged on the side of the column 11 near 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 allows one end of the second hydraulic rod mechanism 12 to rotate horizontally along the first block 13. A locking block 14 is fixedly arranged on the other end of the first block 13. A vertically connected sliding groove 15 and cavity 16 are vertically opened in the middle of the column 11 near the first block 13. The width of the sliding groove 15 is smaller than the width of the cavity 16. The width of the sliding groove 15 is the same as the width of the first block 13 to prevent the first block 13 from shifting in the horizontal direction.The length and width of the locking block 14 are the same as the length and width of the cavity 16. One side of the first block 13 passes through the slide groove 15 and the locking block 14 is disposed in the cavity 16. This ensures a reliable connection between the first block 13 and the column 11, preventing separation of the first block 13 and the column 11, and allows the first block 13 and the locking block 14 to move smoothly in the vertical direction along the slide groove 15 and the cavity 16. At the same time, it also avoids the first block 13 from shifting in the horizontal direction. A support plate 17 is horizontally fixedly disposed at the lower end of the column 11 and directly below the first block 13 to reliably support the third hydraulic rod mechanism 18. The third hydraulic rod mechanism 18 is vertically fixedly disposed 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 locking block 14, and the second hydraulic rod Mechanism 12 moves up and down under the action of the third hydraulic rod mechanism 18. A second block 19 is fixedly installed at the end of the second hydraulic rod mechanism 12. A flat plate 20 is horizontally fixedly installed at the lower end of the second block 19. A motor 21 is vertically fixedly installed at the lower end of the flat plate 20 to ensure the stability of the motor 21. The drive shaft of the motor 21 is connected to one end of the grinding roller 22. The motor 21 drives the grinding roller 22 to rotate. The lower end of the grinding roller 22 is set in the gap between the internal gear ring 8 and the gear 6. The width of the gap between the internal 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 extends, retracts and rotates, the grinding roller 22 moves along the gap to complete the grinding of the burrs at the rim of the gear 6.

[0019] A second screw 23 is vertically fixed at the middle position of the lower end of the shaft 4. A threaded hole 24 is provided on the base plate 1. The second screw 23 is positioned corresponding to the threaded hole 24 and the threads are engaged. The second screw 23 is set in the threaded hole 24, which not only ensures the reliable connection between the second screw 23 and the base plate 1, thereby ensuring the stability of the position of the shaft 4, but also allows the shaft 4 to be replaced according to the different specifications of the gear 6, ensuring the limiting effect of the shaft 4 on the gear 6.

[0020] During operation, the first block 13 and the second hydraulic rod mechanism 12 are moved upward by the third hydraulic rod mechanism 18, so that the gear 6 is sleeved on the shaft 4. The locking nut 7 is tightened, and the internal gear ring 8, which has been 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 moved downward by the third hydraulic rod mechanism 18, and the position of the second hydraulic rod mechanism 12 is adjusted so that the lower end of the grinding roller 22 is located in the gap between the internal gear ring 8 and the gear 6. The motor 21 is started, and the grinding roller 22 rotates to grind the teeth at the rim of the gear 6. As the second hydraulic rod mechanism 12 extends, retracts and rotates, the grinding roller 22 moves along the gap to complete the grinding of the burrs at the rim of the gear 6.
