[0002] Gears refer to mechanical components with gears on the wheel rim that continuously mesh to transmit motion and power. Gears are often used as transmission accessories, so strict requirements are placed on the accuracy of gears. The rough gear blanks need to be finely ground. When the gears are ground, they need to be fixed and then ground. However, most gear clamping devices on the market are too simple in fixing the gears. After long-term use, wear and looseness may lead to the accumulation of positioning errors, affecting the overall quality of gear processing. At the same time, most gear clamping devices have a single functionality and can only clamp gears of the same style. They have poor adaptability to gears of different specifications, resulting in low processing efficiency and increased time consumption.

[0003] Based on this, a clamping device for gear processing that is easy to position is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content

A rotating mechanism 2 for rotating the disk body 4 is provided inside the annular support frame 1, so that the disk body 4 can be rotated, thereby facilitating the processing of the clamped gear. A clamping mechanism 5 for clamping the gear is provided on the top of the disk body 4, so that it can clamp gears of different sizes and styles.

[0026] In one embodiment, Figure 2As shown, the rotating mechanism 2 includes a groove 201, an annular connecting sleeve 202, a roller 203, a driving motor 204, a first gear 205, a second gear 206 and a connecting rod 207. The inner part of the annular support frame 1 is provided with a groove 201, and the inner wall of the groove 201 is slidably connected with the annular connecting sleeve 202. One side of the annular connecting sleeve 202 is provided with multiple groups of rollers 203, which can reduce the friction between the annular connecting sleeve 202 and the annular support frame 1, so that the connecting plate 3 can be better rotated in the groove 201 through the annular connecting sleeve 202. The inside of the annular support frame 1 is fixedly connected to a driving motor 204, and the top of the driving motor 204 is fixedly connected to a first gear 205. Starting the driving motor 204 can drive the first gear 205 to rotate, and the surface of the first gear 205 is meshingly connected to the second gear 206. The bottom of the connecting rod 207 is fixedly connected to the second gear 206, and the top is fixedly connected to the connecting plate 3. When the first gear 205 rotates, it can drive the second gear 206 to rotate, and the second gear 206 can drive the connecting plate 3 to rotate through the connecting rod 207.

[0027] In one embodiment, Figure 5 As shown, the clamping mechanism 5 includes a slide groove 501, a slider 502, a connecting block 503, a limiting groove 504, a limiting block 505, a base claw 506, a threaded hole 507 and a screw 508. The inside of the disk body 4 is provided with a plurality of slide grooves 501, and the inner wall of the slide groove 501 is slidably connected with the slider 502 so that the slider 502 can be inserted into the slide groove 501. One side of the slider 502 is fixedly connected with the connecting block 503. The top of the slider 502 is provided with a limiting groove 504, and the inner wall of the limiting groove 504 is slidably connected with the slider 502. A limit block 505 is dynamically connected, and a base claw 506 is fixedly connected to the top of the limit block 505, so that the base claw 506 can be inserted into the limit groove 504 through the limit block 505. A threaded hole 507 is provided on the top of the base claw 506, and a screw 508 is threadedly connected to the inner wall of the threaded hole 507. One end of the screw 508 cooperates with the slider 502. When the screw 508 is turned, the screw 508 passes through the threaded hole 507 and is threadedly connected to the slider 502, so that the base claw 506 can be fixed on the slider 502.

[0028] In one embodiment, Figure 5 As shown, the inner wall size of the limit groove 504 is consistent with the outer wall size of the limit block 505. When the limit block 505 slides inside the limit groove 504, the limit groove 504 can limit the sliding of the limit block 505 to prevent the limit block 505 from shaking inside the limit groove 504.

[0029] In one embodiment, Figure 2 As shown, one end of the base jaw 506 is convex, which can better clamp the gear.

[0030] In one embodiment, Figure 4As shown, a wedge-shaped sleeve 6 is provided on one side of the connecting block 503, and a connecting groove 7 is provided on the surface of the wedge-shaped sleeve 6. The interior of the connecting groove 7 is oblique, and the connecting groove 7 cooperates with the connecting block 503. A threaded rod 8 is fixedly connected to the bottom of the wedge-shaped sleeve 6. When the wedge-shaped sleeve 6 moves upward, the connecting groove 7 also moves upward, and the connecting block 503 matched with it will slide backward, converting the axial movement of the piston of the slider 502 into the radial movement of the slider 502, so that the slider 502 slides in the slide groove 501 on the disk body 4 to realize the clamping of the base claw 506.

[0031] In one embodiment, Figure 3 As shown, the surface of the threaded rod 8 is threadedly connected with a worm wheel 9. When the worm wheel 9 rotates, the threaded rod 8 moves up and down inside it. The surface of the worm wheel 9 is meshingly connected with a worm 10. When the worm 10 rotates, it can drive the worm wheel 9 to rotate. When the worm wheel 9 rotates, one end of the worm 10 is rotatably connected to the disk body 4 and the other end is fixedly connected to a four-corner cylindrical head screw 11. The four-corner cylindrical head screw 11 is driven by turning the wrench to rotate the worm 10.

[0032] In one embodiment, Figure 6 As shown, a dust cover 12 is provided on the top of the disc body 4 to prevent machining debris from entering the inside of the disc body 4 .

[0033] Working principle: The above embodiment discloses a clamping device for gear processing that is easy to position. When in use, the base jaw 506 is inserted into the limit groove 504 through the limit block 505, and the screw 508 is turned. The screw 508 passes through the threaded hole 507 and is threadedly connected with the slider 502, so that the base jaw 506 can be fixed on the slider 502. When processing the gear, the gear is placed on the dust cover 12, and the wrench is turned to drive the four-cornered cylindrical head screw 11 to rotate the worm 10. When the worm 10 rotates, it drives the worm wheel 9 to rotate. When the worm wheel 9 rotates, the threaded rod 8 moves up and down inside it. When the wedge core sleeve 6 moves upward, the connecting groove 7 also moves upward, and the connecting block 503 matched with it will slide backward, converting the axial movement of the piston of the slider 502 into the radial movement of the slider 502, so that the slider 502 slides in the slide groove 501 on the disk body 4 to achieve the clamping of the base jaw 506. The gear is fixed on it, and through the process of clamping and loosening the base jaws 506, gears of different sizes can be fixed, so that the processing accuracy is high, and manual clamping can avoid wear and loosening of the fixture after long-term use, resulting in accumulation of positioning errors and affecting the overall quality of gear processing. The driving motor 204 is started to drive the first gear 205 to rotate. When the first gear 205 rotates, it can drive the second gear 206 to rotate. The second gear 206 can drive the connecting plate 3 to rotate through the connecting rod 207, and the disk body 4 can be driven to rotate through the connecting plate 3, so as to facilitate the processing of the clamped gear. At the same time, when it is necessary to clamp gears of different styles, the screws 508 are unscrewed so that the base jaws 506 can be disassembled for replacement. By replacing base jaws 506 of different styles, it can better clamp gears of different styles, making the clamping of the device more stable.
