[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 4 , a gear grinding device for gear processing, comprising a base 1, a rotating base 2 is rotatably mounted on the base 1, and a grinding mechanism is mounted on the base 1;

[0024] A sleeve 3 is vertically fixedly installed at the center of the rotating seat 2, and a plurality of moving grooves are provided on the rotating seat 2, and moving blocks 4 are slidably installed in the plurality of moving grooves, and the plurality of moving blocks 4 are arranged in a circle with the sleeve 3 as the center, and an adjustment component for simultaneously driving the plurality of moving blocks 4 to approach or move away from each other is provided in the sleeve 3, and a plurality of strip holes are provided on the surface of the sleeve 3, and the adjustment component comprises a threaded rod 12 vertically rotatably installed on the rotating seat 2, a lifting block 13 threadedly sleeved on the threaded rod 12, and a plurality of support rods 14 rotatably installed on the lifting block 13, one end of the plurality of support rods 14 respectively passes through the plurality of strip holes and is rotatably connected to the plurality of moving blocks 4, an adjustment block 15 is fixedly installed on the upper end of the threaded rod 12, and an anti-slip pattern is provided on the surface of the adjustment block 15;

[0025] The gear to be polished is placed on the rotating seat 2, the sleeve 3 is inserted into the inner ring of the gear, and then the adjusting block 15 is rotated to drive the threaded rod 12 to rotate, thereby driving the lifting block 13 to move vertically downward. During the vertical downward movement of the lifting block 13, multiple moving blocks 4 will be driven to move away from each other through multiple support rods 14 until the moving block 4 contacts the inner wall surface of the gear, and forces in different directions are applied to the gear through multiple moving blocks 4, thereby limiting the movement of the gear on the horizontal plane.

[0026] A rotating plate 5 is rotatably installed on the upper surface of the moving block 4, and a rectangular groove is provided on the upper surface of the moving block 4, and a rectangular plate 6 is vertically inserted in the rectangular groove. The upper end of the rectangular plate 6 is connected to the rotating plate 5 through a connecting component. A moving groove is provided on the side of the moving block 4 away from the sleeve 3, and a transmission component for driving the rectangular plate 6 to move vertically up and down is provided in the moving groove. A slide groove is provided on the rotating plate 5, and the connecting component includes a slider 7 slidably installed in the slide groove and a strut 8 rotatably installed on the slider 7. One end of the strut 8 away from the slider 7 is fixedly connected to the rectangular plate 6. The transmission component includes a trapezoidal block 9 slidably installed in the moving groove, a top block 10 fixedly installed at one end of the trapezoidal block 9, and two spring rods 11 symmetrically fixedly installed on the top block 10, one end of the two spring rods 11 are fixedly installed on the inner wall of the moving groove, and a rectangular hole is provided on the rectangular plate 6, and the inclined end of the trapezoidal block 9 is inserted in the rectangular hole;

[0027] When the moving block 4 contacts the gear, the top block 10 will contact the gear first, thereby driving the trapezoidal block 9 to move into the moving groove, and the spring rod 11 is compressed. Since the inclined end of the trapezoidal block 9 is inserted in the rectangular hole, the rectangular plate 6 will be driven to move vertically downward under the action of the inclined surface. During the movement of the rectangular plate 6, the slider 7 will be driven to move vertically downward through the support rod 8. Since the slider 7 is slidably mounted on the rotating plate 5, the slider 7 will drive the rotating plate 5 to rotate in the direction of the gear during the movement until the rotating plate 5 contacts the gear, exerting a downward force on the gear, limiting the upward movement of the gear, further improving the stability of the grinding device to fix the gear, and effectively preventing the deviation of the gear grinding size.

[0028] A non-slip pad is fixedly installed on one side of the multiple top blocks 10 away from the moving block 4. The non-slip pad is made of rubber and can increase the friction between the top blocks 10 and the gears to prevent the gears from rotating during the grinding process.

[0029] In the utility model, when the moving block 4 contacts with the gear, the rectangular plate 6 will be driven to move vertically downward through the transmission assembly. During the movement of the rectangular plate 6, the rotating plate 5 will be driven to rotate in the direction of the gear through the connecting assembly until the rotating plate 5 contacts with the gear, exerting a downward force on the gear to limit the upward movement of the gear, further improving the stability of the grinding device to fix the gear, and effectively preventing deviations in the grinding size of the gear.

[0030] In general, in response to the technical problem: during the processing, the gear may move in the vertical direction, which may cause deviations in the size of the gear grinded; a technical solution is adopted: a downward force is applied to the gear through the cooperation of the moving block 4, the transmission assembly, the rectangular plate 6, the rotating plate 5 and the connecting assembly; because the implementation process of the technical solution is: when the moving block 4 contacts the gear, the rectangular plate 6 will be driven to move vertically downward through the transmission assembly, and during the movement of the rectangular plate 6, the rotating plate 5 will be driven to rotate in the direction of the gear through the connecting assembly until the rotating plate 5 contacts the gear, applying a downward force to the gear, and limiting the upward movement of the gear; so the technical problem can definitely be solved, and the technical effect achieved is: improving the stability of the grinding device to fix the gear, and effectively preventing deviations in the grinding size of the gear.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
