[0015] A method for using a positioning sawtooth device for forging a spur gear comprises the following steps:

[0016] Step 1: Open the hinged processing box door, place the model gear on the side of the electromagnet output end, and ensure that the model gear is located in the middle of the baffle, then turn on the electromagnet and the No. 2 electric telescopic rod, and the electromagnet will adsorb and fix the model gear;

[0017] Step 2: Open the No. 2 electric telescopic rod, the output end of the No. 2 electric telescopic rod extends out, and pushes the long plate and the short plate in the middle of the inner wall of the adjustment box to the side of the electromagnet. The adjustment rod fixed on the short plate extends out of the adjustment box, and the adjustment rod pushes the adjustment disk to move. The moving adjustment disk drives the threaded rod and the threaded cylinder to rotate with the connection part of the No. 2 swivel seat and the No. 3 swivel seat as the rotation center. The threaded rod drives the No. 1 swivel seat to slide in the adjustment groove at the same time, and finally the four threaded rods are rotated to the horizontal position. In the process of the four threaded rods rotating to the horizontal position, the four extrusion plates are arranged away from each other, and finally stick to the model gear, and the model gear is fixed for the second time;

[0018] Step 3: Place the original gear on the other side of the baffle, then open the No. 1 electric telescopic rod, which pushes the long plate and the short plate on one side of the adjustment box to move, and at the same time drives the adjustment rod on this side to extend out of the adjustment box. The adjustment rod on this side pushes the adjustment disk to move in the same way, so that the extrusion plates on this side move away from each other, and the original gear is fixed;

[0019] Step 4: Open the hydraulic cylinder, the output end of the hydraulic cylinder drives the hydraulic rod to retract, and at the same time drives the No. 1 fixed box and the No. 2 fixed box to move, and finally makes the positioning gear at the output end of the positioning motor mesh with the model gear;

[0020] Step 5: Turn on the sawtooth motor and the positioning motor, and adjust the speed of the positioning motor first. The staff can manually control the regular extension and retraction of the output end of the telescopic cylinder, or use an external control computer to control it. The purpose is to make the sawtooth motor move back and forth, and ensure that the positioning gear controlled by the positioning motor rotates one circle, and the teeth of the positioning gear mesh with the model gear once, so that the model gear rotates a certain angle. The model gear also drives the adjustment box and the original gear at the other end to rotate a certain angle. The output end of the telescopic cylinder extends and retracts once, thereby driving the sawtooth gear at the output end of the sawtooth motor to contact the original gear once, so that the sawtooth gear cuts the original gear at different angles.

[0021] Step 6: After the model gear rotates one circle, the processed original gear that is consistent with the model gear teeth can be obtained. The staff opens the hinged processing box door, turns off the telescopic cylinder, sawtooth motor and No. 1 electric telescopic rod, removes the processed original gear, replaces it with a new original gear, and repeats steps 3 and 6 to continue processing the newly replaced original gear.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting an adjustment disk, a No. 1 swivel seat, a threaded rod, a No. 2 swivel seat, a No. 3 swivel seat and a baffle plate, the position of the adjustment disk can be changed, and the movable adjustment disk can be used to drive the threaded rod and the threaded barrel to rotate with the connection part of the No. 2 swivel seat and the No. 3 swivel seat as the rotation center, and the threaded rod simultaneously drives the No. 1 swivel seat to slide in the adjustment groove, and finally the four threaded rods are rotated to a horizontal position, so that the four extrusion plates are separated from each other and finally abut against the model gear, which is used to fix the original gear and the model gear. The threaded rod and the threaded barrel can be adjusted by rotating the threaded barrel to extend the distance between the four extrusion plates, so that the device can fix the original gears and model gears of different diameters and models, and the electromagnet is used to strengthen the fixing strength of the model gear to ensure the accurate positioning of the model gear.

[0023] By setting up the telescopic cylinder, positioning motor and positioning gear, the positioning motor controls the positioning gear to rotate one circle each time, and the teeth of the positioning gear mesh with the model gear once, driving the model gear to rotate a certain angle. The model gear simultaneously drives the adjustment box and the original gear at the other end to rotate a certain angle. The output end of the telescopic cylinder telescopes once, thereby driving the sawtooth gear at the output end of the sawtooth motor to contact the original gear once, so that the sawtooth gear performs positioning cutting on the original gear at different angles, thereby reducing the difficulty of positioning processing of the original gear and improving the quality of the finished product after the original gear is processed.
