[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-6 As shown, this utility model provides a fixed fixture for gear processing, including a table panel 1, a drive mechanism 2 is provided at the bottom of the table panel 1, four first connectors 3 are provided on the outer wall of the drive mechanism 2, the drive mechanism 2 is connected to four first fixing mechanisms 5 through the four first connectors 3 respectively, and four second connectors 4 are provided on the outer wall of the drive mechanism 2, the drive mechanism 2 is connected to four second fixing mechanisms 6 through the four second connectors 4 respectively.

[0029] The first fixing mechanism 5 includes four lifting rods 501. The four lifting rods 501 are fixedly connected to four first connectors 3 respectively. A connecting frame 502 is fixedly connected to the top of the lifting rod 501. The inner wall of the connecting frame 502 is provided with moving grooves on all four sides. The connecting frame 502 is slidably connected to four moving blocks 503 through the four moving grooves respectively. A clamping block 504 is fixedly connected to one end of each of the four moving blocks 503. A connecting block 505 is fixedly connected to the middle of the bottom of the inner wall of the connecting frame 502. Two springs 506 are fixedly connected to all four sides of the connecting block 505. One end of each of the two springs 506 is connected to the corresponding end of the same moving block 503.

[0030] The drive mechanism 2 includes four support rods 201, all of which are fixedly connected to the bottom of the platform 1. One end of each support rod is fixedly connected to the outer wall of the same support platform 202. A cylinder 203 is fixedly connected to the top of the support platform 202. A connecting plate 204 is fixedly connected to the output end of the cylinder 203. The outer wall of the connecting plate 204 is fixedly connected to one end of each of the four first connectors 3. The outer wall of each support rod is fixedly connected to the inner wall of the second connector 4. By setting the drive mechanism 2, when the fixture is in use, the cylinder 203 drives the connecting plate 204 to move, thereby driving the lifting rod 501 to move. This allows the lifting rod 501 to make the height of the clamping block 504 flush with the height of the gear body 8, thus facilitating the clamping and fixing of the gear body 8 by the clamping block 504 and ensuring the convenience of clamping and fixing of the fixture.

[0031] The second fixing mechanism 6 includes four electric telescopic rods 601, each fixedly connected to one of four second connectors 4. A piston 602 is fixedly connected to the output end of each electric telescopic rod 601. The outer wall of the piston 602 is slidably connected to the inner wall of a negative pressure sleeve 603. The interior of the negative pressure sleeve 603 is connected to one end of two connecting pipes 604, and the other ends of the two connecting pipes 604 are connected to the interior of two suction cups 605. The top of the suction cups 605 is flush with the top of the tabletop 1. The top has several mounting slots, and the table panel 1 is fixedly connected to the suction cup 605 through the mounting slots. By setting the second fixing mechanism 6, the fixing fixture can pre-fix the gear body 8 during use, which facilitates the secondary fixing of the gear body 8 by the first fixing mechanism 5. Furthermore, by initially fixing the gear body 8, the position of the gear body 8 can be initially positioned, avoiding the situation of unstable clamping due to inaccurate positioning during the subsequent clamping and fixing of the rack body. Moreover, the stability of the gear body 8 can be further guaranteed through multiple fixing methods.

[0032] The top of the table panel 1 has four through holes 7, and the inner diameter of the four through holes 7 is larger than the outer diameter of the connecting frame 502. The clamping end of the clamping block 504 is set to be arc-shaped.

[0033] The top of the table panel 1 is provided with four gear bodies 8, which are concentrically arranged with four through holes 7. By arranging the gear bodies 8 and the through holes 7 concentrically, the four clamping blocks 504 can simultaneously clamp and fix the inner wall of the rack body, ensuring the uniformity of clamping and thus ensuring the stability of clamping.

[0034] Working principle:

[0035] In use, first place the gear body 8 concentrically with the through hole 7, then activate the electric telescopic rod 601. The electric telescopic rod 601 drives the piston 602 to slide along the negative pressure sleeve 603, causing the negative pressure sleeve 603 to draw air. During the air-drawing process, the suction cup 605 is subjected to negative pressure through the connecting pipe 604. The suction cup 605 can then initially fix the gear body 8. Then, activate the cylinder 203. The output end of the cylinder 203 drives the connecting plate 204 to move upward. The upward movement of the connecting plate 204 drives the first connecting plate to move upward. The device 3 moves upward, thereby driving the lifting rod 501 to move upward. The upward movement of the lifting rod 501 drives the connecting frame 502 to move upward. Due to the pressure between the inner wall of the through hole 7 and the clamping block 504, the clamping block 504 presses against the moving block 503 and causes the spring 506 to contract. When the lifting frame drives the clamping block 504 to move upward to a certain position, the inner wall of the through hole 7 is released from the pressure of the clamping block 504. Then, the clamping block 504 moves outward under the action of the spring 506, thus fixing the inner wall of the gear body 8 through the clamping block 504.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
