Working principle: when the side surface of the workpiece of the bevel gear needs to be cut, firstly, a round hole in the middle of the workpiece is manually aligned with the sliding cylinder 401 to push the workpiece, in the pushing process, the sliding disc 701 is driven to move, and then the connecting wire 706 is driven to be inserted into the small joint 707, so that the power supply is switched on to enable the electromagnet block 705 to be electrified to generate magnetic force, and the rear end surface of the workpiece is adsorbed through the magnetic force.

Meanwhile, the servo motor E405 drives the screw rod of the screw rod moving mechanism A404 to rotate, so that the sliding block of the screw rod moving mechanism A404 is driven to move, the sliding cylinder 401 is further driven to move, the rotating rod 402 is driven to move along with the movement of the sliding cylinder 401, and in the moving process of the rotating rod 402, the rod at the rear end of the rotating rod 402 is matched with the sliding groove in the cylinder 403, so that the rotating rod 402 is driven to move along with the sliding cylinder 401, the rod at the rear end of the rotating rod 402 is driven to rotate along the sliding groove, the rotating rod 402 is driven to rotate, the special-shaped disc 406 is driven to rotate, the sliding groove on the special-shaped disc 406 is driven to push the sliding support rod 407 to move, the sliding support rod 407 moves to be close to the front end face of a workpiece, and the sliding support rod 407 can contact the front end face of the workpiece, and the sliding support rod 407 presses the front end face of the workpiece.

One of the rotating wheels 502 is driven to rotate by the servo motor C501, and the other rotating wheels 502 are driven to rotate by the belt, so that the arc plate 504 is driven to rotate, and the protruding blocks on the side surface of the arc plate 504 squeeze the inner side of the round hole in the center of the workpiece.

When cutting, the workpiece is required to be inclined at a certain angle, so that the cut teeth are kept uniform and equal in size.

The servo motor D610 drives the circular ring 611 to rotate, so that the workpiece is driven to incline; since the inclination angle of the workpiece is changed, the position of the workpiece to be cut is correspondingly changed, so that the servo motor B309 drives the cylindrical gear A301 to rotate and then drives the rack A302 to move, thereby driving the support rod A303 to move and further driving the servo cylinder A304, the support rod B305, the servo motor A306 and the cutting blade 307 to move to the position capable of cutting the workpiece.

During cutting, the supporting rod B305, the servo motor A306 and the cutting blade 307 are driven to descend through the servo motor A304, so that the cutting blade 307 can contact the surface of a workpiece, the cutting blade 307 is driven to rotate through the servo motor A306, the workpiece is cut, meanwhile, the oil drum 2 is required to be stored for pouring lubricating oil during cutting, deformation and processing failure of the overheated workpiece of a turning tool in the cutting process can be prevented, and meanwhile, a lubricating effect can be achieved.

In the cutting process, the workpiece is required to continuously move forwards and backwards, so that the motor of the screw rod moving mechanism B601 drives the screw rod of the screw rod moving mechanism B601 to rotate, and then the sliding block 602 is driven to move, so that the workpiece is driven to move forwards and backwards, and cutting is facilitated.

The number of teeth of the workpiece to be cut is manually set, so that corresponding numerical values are calculated through a computer, a motor of the screw rod moving mechanism C614 drives a screw rod of the screw rod moving mechanism C614 to rotate, a sliding block of the screw rod moving mechanism C614 is driven to move, a long rod on the sliding block of the screw rod moving mechanism C614 is further driven to move to a corresponding position, after the sliding block 602 touches the long rod on the screw rod moving mechanism C614, the sliding block 602 stops moving, so that the distance of the sliding block 602 for pushing the rack B603 is fixed, and the rack B603 drives the cylindrical gear B604 to rotate at a fixed angle; the closer the long rod of the lead screw moving mechanism C614 is to the slide block 602, the shorter the slide block 602 pushes the rack B603, and thus the smaller the angle at which the cylindrical gear B604 rotates.

During the movement of the slide block 602, the profiled bar 608 is inserted into the circular bar 606, and at this point the profiled bar 608 and the cross recess of the circular bar 606 cooperate with each other.

The sliding block 602 can push the rack B603 to move in the moving process, so that the rack B603 drives the cylindrical gear B604 to rotate, and then drives the bevel gear C605 to rotate, thereby driving the fixed bracket B607 to rotate, further driving the special-shaped rod 608 to rotate, thereby driving the special-shaped stirring disc 609 to rotate, and then driving the rotating circular ring frame 708 to rotate by a certain angle, and the rotating circular ring frame 708 drives the fixed bracket C702 to rotate, so that the bevel gear rotates by a certain angle and then performs one-time cutting, and then the smaller the angle of workpiece rotation is, the smaller the tooth pitch of the cut teeth is, the more the teeth are, and conversely, the wider the tooth pitch is, and the fewer the teeth are.

In order to prevent the rotating circular ring frame 708 from rotating randomly in the moving process, the servo cylinder B613 stretches and contracts to drive a plate at the front end of the servo cylinder B613 to press the side face of the rotating circular ring frame 708, so that the rotating circular ring frame 708 is prevented from rotating.
