With the development of production, the smooth operation of gears has been emphasized. Gears are widely used in mechanical transmissions. It refers to a mechanical element with toothed keys on the rim that continuously mesh to transmit motion and power.

[0003] In a Chinese utility model patent, such as the utility model of CN217316247U, a positioning device for gear processing is disclosed, including a box body and a feeding position adjustment mechanism. Through the setting of the feeding position adjustment mechanism, the utility model can be used to make it have the functions of rapid feeding and direction adjustment of materials. It is not only simple to operate, but also improves work efficiency.

[0004] The above-mentioned technology positions the gear by driving the upper placement plate to move downward through an electric telescopic rod, and then plays a role in fixing and pressing the material. However, when the specifications of the gears are different and the diameter length of the inner circular groove is greater than the diameter length of the placement plate, the upper placement plate cannot perform the pressing operation on the material, and the specification of the upper placement plate needs to be changed to adapt to the diameter of the gear circular groove, and the universality is relatively low. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems in the background technique, and a positioning device for gear processing is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Referring to Figures 1-3 , a positioning device for gear processing includes a base 1. The top surface of the base 1 is rotatably connected to a turntable 2. The base 1 drives the turntable 2 to rotate through a gear reduction mechanism. The gear reduction mechanism includes an internal gear ring 16, and the internal gear ring 16 is fixedly installed on the bottom surface of the turntable 2. A motor 18 is fixedly installed inside the base 1. The output shaft of the motor 18 is connected to a driving gear 17, and the driving gear 17 meshes with the internal gear ring 16. It is worth noting that by making the pitch circle diameter of the driving gear 17 smaller than the pitch circle diameter of the internal gear ring 16, the transmission ratio can be increased, enabling the turntable 2 to rotate slowly, facilitating the alignment of the electric telescopic rod 6 with the top cover 9;

[0023] A fixing frame 4 is fixedly installed on the outside of the base 1. A waste box 5 is slidably connected inside the fixing frame 4. An electric telescopic rod 6 is fixedly installed on the top wall of the fixing frame 4. A fixing frame 4 is fixedly installed on the outside of the base 1. A waste box 5 is slidably connected inside the fixing frame 4. An electric telescopic rod 6 is fixedly installed on the top wall of the fixing frame 4;

[0024] A plurality of extension plates 3 are symmetrically installed on the outside of the turntable 2. A sleeve 7 is fixedly installed on the top surface of each extension plate 3. A push rod 8 is slidably connected inside each sleeve 7. A top cover 9 is fixedly installed at the top end of each push rod 8. The other end of each push rod 8 is fixedly installed with a first piston 11, and the first piston 11 is elastically connected to the top wall of the sleeve 7. A spring 12 is fixedly installed on the top surface of each first piston 11, and the top end of each spring 12 is fixedly connected to the top wall of the sleeve 7. It is worth noting that the air inside the sleeve 7 can be compressed by the sliding of the first piston 11, and at the same time, the spring 12 facilitates the upward reset of the first piston 11;

[0025] A plurality of connecting cylinders 10 are symmetrically installed on the outer side of each sleeve 7. A second piston 13 is slidably connected in each connecting cylinder 10. One end of each second piston 13 is fixedly installed with a connecting rod 14, and the connecting rod 14 is slidably connected in the connecting cylinder 10. A plurality of connecting rods 14 on the same side are jointly installed with a rubber plate 15. It should be noted that when the first piston 11 moves downward, compressed air is generated, which further pushes the second piston 13 to slide outward, thereby driving a plurality of connecting rods 14 to slide outward, and clamping and fixing the gear through the rubber plate 15.

[0026] A through groove 21 is formed at one end of each extension plate 3 away from the turntable 2. A rotating door 20 is rotatably connected to the outside of each through groove 21. A fixing rod 19 is fixedly installed on the outside of the fixing frame 4. The installation height of the fixing rod 19 corresponds to the height of the through groove 21, and the thickness of the fixing rod 19 is smaller than the thickness of the through groove 21. It should be noted that when the turntable 2 rotates, the fixing rod 19 can rotate into the through groove 21 to provide a reference for the staff. When the fixing rod 19 is located in the through groove 21 and the rotating door 20 does not rotate, it indicates that the electric telescopic rod 6 is directly above the push rod 8 at this time, and the electric telescopic rod 6 can be driven to extend to fix the gear.

[0027] When the present utility model is in use, first place the gear on the outside of the sleeve 7, and then start the motor 18. By driving the cooperation of the gear 17 and the internal gear ring 16, the turntable 2 and the extension plate 3 can be driven to rotate slowly. When the turntable 2 rotates by one-fourth, at this time the fixing rod 19 is located in the through groove 21 and the rotating door 20 does not rotate, then the motor 18 can be stopped, and thus the positions of the turntable 2 and the extension plate 3 are fixed.

[0028] Then the electric telescopic rod 6 can be started. By extending the electric telescopic rod 6, the top cover 9 is pressed downward, which further pushes the push rod 8 and the first piston 11 to slide in the sleeve 7, thereby compressing the air in the sleeve 7 and pushing the second piston 13 to slide outward. While sliding, the connecting rod 14 is driven to slide outward, and then the gear is clamped and fixed from the inner side of the gear through a plurality of rubber plates 15. By fixing in this way, the clamping and fixing of gears of different specifications can be realized, enhancing the universality of the device.

[0029] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
