[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the 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. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0024] Embodiment:

[0025] Please refer to Figure 1 - Figure 2 , the present utility model provides a positioning device for gear production, including a rectangular tube 1, a circular plate 2 is fixedly installed at the front end of the rectangular tube 1, a cylinder 3 is fixedly installed inside the rectangular tube 1, a substrate 4 is fixedly installed at the end of the inner rod of the cylinder 3, a motor 5 is fixedly installed on the substrate 4, a limiting column 6 is fixedly installed at the end of the rotating shaft of the motor 5, and a pressing head 7 is fixedly installed at the end of the limiting column 6.

[0026] Specifically, the number of the motors 5 is two to four.

[0027] Specifically, the side of the substrate 4 is in contact with the inner cavity wall of the rectangular tube 1, and the inner cavity wall of the rectangular tube 1 is coated with lubricating oil. The substrate 4 has guidance during forward and backward movement, with small friction and low noise.

[0028] Specifically, the side of the limiting column 6 is in contact with the through-hole wall of the circular plate 2. The gear is sleeved on the limiting column 6, and the limiting column 6 has a fixing effect on it to prevent the gear from skewing.

[0029] Specifically, as Figure 1 shown, the pressing head 7 is of an obliquely narrowing structure, and the pressing heads 7 do not interfere with each other during rotation.

[0030] Working principle:

[0031] When in use, the motor 5 drives the limit post 6 to rotate, rotates the pressing head 7 inwards, then the air cylinder 3 extends, pushes the pressing head 7 to the outer side position of the gear, presses the gear against the circular plate 2, with the side of the gear located outside the circular plate 2. Then the motor 5 drives the limit post 6 to rotate again, rotates the pressing head 7 to the position corresponding to the gear, the air cylinder 3 contracts, and the pressing head 7 presses on the gear to fix the gear.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
