As a further proposal of the invention, the exhaust disc 32 is communicated with an air nozzle 38, and the air nozzle 38 is obliquely downward opposite to the surface of the bearing disc 20; in operation, the gas exhausted from the exhaust tray 32 is ejected from the gas-ejecting pipe 38, and the gas-ejecting pipe 38 is inclined downwards to face the tray 20, so that the exhausted gas can better impact the surface of the tray 20, and the cleaning effect is improved.

As a further scheme of the invention, two sides of the arc chute 22 are fixedly connected with sealing gaskets 39, and the two sealing gaskets 39 wrap the lifting rod 21; during operation, when the lifting rod 21 moves back and forth on the inner wall of the arc chute 22, the two sealing gaskets 39 always cover the arc chute 22, so that the situation that scraps generated by gear processing splash into the arc chute 22 to influence the movement of the lifting rod 21 in the arc chute 22 is avoided.

As a further scheme of the invention, the gear cutting mechanism comprises a hydraulic cylinder 40, the hydraulic cylinder 40 is fixedly connected to the front side of the top of the base 1, the output end of the hydraulic cylinder 40 is fixedly connected with a tool rest 41, the tool rest 41 slides back and forth along the surface of the base 1, and the tool rest 41 is rotatably connected with a hob 42 for cutting a gear blank; in operation, after the gear blank is fixed to the rotary base 3, the hydraulic cylinder 40 drives the tool rest 41 to move backward, so that the hob 42 is brought into contact with the gear blank, and the gear blank is cut by the hob 42 rotating at a high speed, thereby obtaining a desired gear.

A high-precision gear manufacturing method comprises the following specific steps:

the method comprises the following steps: the motor 2 drives the rotary base 3 to rotate, a worker moves the gear blank downwards along the guide rod 4, and the bearing disc 20 drives the support frame 10, the first driving wheel 7 and the lifting disc 8 to synchronously move downwards;

step two: when the brush bristles 13 contact with the surface of the rotating base 3 along with the continuous descending of the conveyor belt 12, the brush bristles 13 moving along with the conveyor belt 12 clean the surface of the rotating base 3, and the impeller 19 agitates and conveys the scraps on the surface of the rotating base 3 to the right and cooperates with the rotating base 3 so as to collect and discharge the scraps remained on the surface of the rotating base 3;

step three: as the conveyor belt 12 continues to descend, the steering rod 25 is in contact with the steering block 26, and under the action of the rotating base 3, the steering block 26 pushes the steering rod 25 to move backwards, so that the support frame 10 rotates backwards, and the support frame 10 drives the lifting rod 21 to slide forwards along the arc chute 22 to separate from the rotating base 3;

step four: and (4) locking the gear blank after the gear blank is lowered onto the rotary base 3, and starting the gear cutting mechanism to perform gear hobbing on the gear blank.

The working principle is as follows: the motor 2 is started, the motor 2 drives the rotary base 3 to rotate, a worker moves a tooth blank downwards along the guide rod 4, the receiving disc 20 is driven to synchronously move downwards after the tooth blank is pressed onto the receiving disc 20, the receiving disc 20 drives the support frame 10, the first transmission wheel 7 and the lifting disc 8 to synchronously move downwards, the first transmission wheel 7 rotates under the action of the external thread of the screw rod 6, the second transmission wheel 11 is matched to drive the transmission belt 12 to transmit, the transmission belt 12 drives the first rotating shaft 15 and the first gear 16 to synchronously move through the first base 14, the first gear 16 rotates when rolling along the surface of the rack 17, the rotating first gear 16 drives the elastic telescopic rod 18 and the impeller 19 to synchronously rotate through the first rotating shaft 15, the conveying belt 12 continuously descends, and when the bristles 13 contact with the surface of the rotary base 3, the bristles 13 moving along the conveying belt 12 clean the surface of the rotary base 3, impeller 19 stirs the piece on rotating base 3 surface and carries right, cooperation pivoted rotating base 3, thereby collect and remove the remaining piece in rotating base 3 surface, realized the remaining clastic clearance in rotating base 3 surface, along with conveyer belt 12 continues to descend, steering column 25 and the contact of turning to piece 26, under rotating base 3's effect, turn to piece 26 and promote steering column 25 rearward movement, thereby make support frame 10 rotate backward, support frame 10 drives lifter 21 and slides forward along circular arc spout 22, break away from rotating base 3, avoid influencing the laying of tooth base on rotating base 3.
