2. The control method of the operation control system of the hob main shaft of the high-speed precision gear hobbing machine according to claim 1, characterized by comprising the following steps:
the method comprises the following steps: the workpiece (3) is arranged on a fixture in transmission connection with an output shaft of a first driving motor (2), before the device runs, a first electromagnet (16) is controlled to be electrified to generate magnetism opposite to the magnetic pole of a magnetic disc (15), the magnetic disc (15) is attracted, the magnetic disc (15) is linked with a connecting rod (17) to act, and a sliding sleeve (14) is pulled towards one side of a third gear disc (12) under the action of a ball ring (19) which is axially fixed on the connecting rod (17), so that a fifth gear disc (22) is clamped with the sliding sleeve (14);
step two: the servo motor (18) is started to act, an output shaft of the servo motor (18) is in transmission connection with the transmission rod (21) to rotate, the fifth gear disc (22) is limited with the sliding sleeve (14), so that the fourth gear disc (13) is transmitted, and the fourth gear disc (13) is smaller than the first gear disc (10) in diameter, so that the angular speeds are different when the linear speeds are the same, and the transmission precision is improved;
Step three: the first gear disc (10) is in transmission connection with the second screw (702) to rotate, meanwhile, the second electromagnet (28) is electrified to obtain magnetism the same as the magnetic pole on one side of the magnetic plate (27), so that the magnetic plate (27) is pushed to the inner side, balls (26) embedded on the inner side of the fixing ring (25) move to the inner side, and due to the fact that extrusion force exists on the two sides, the positions of the balls (26) are limited, and then the first screw (701) and the second screw (702) are fixedly connected, and in the transmission process of the gear disc to the screw mechanism (7), two sleeves (8) positioned on the gear disc are in position transmission, so that the first driving motor (2) and the second driving motor (5) move to the middle position at the same time;
step four: when the first driving motor (2) drives the workpiece (3) to the position on one side of the hob (4), the second driving motor (5) drives the stabilizing cone (6) to be in contact with the middle rod of the clamp, so that the axial position of the middle rod is stabilized;
step five: the second electromagnet (28) is powered off, the magnetic plate (27) loses the limitation on the ball (26), so that the second screw (702) and the first screw (701) rotate relatively, the servo motor (18) drives the workpiece (3) to move gradually towards the hob (4) through the second screw (702), the hob (4) rotates at a constant speed through the transmission of an external driving mechanism, and meanwhile, the first driving motor (2) and the second driving motor (5) rotate in a manner of being matched with the rotating speed of the hob (4), so that the horizontal stability of a groove of the hob (4) on the workpiece (3) is ensured, and the workpiece (3) is machined;
Step six: the magnetic plate (27) fixes the first screw rod (701) and the second screw rod (702) under the action of the second electromagnet (28), the first electromagnet (16) generates magnetism the same as the magnetic pole of the magnetic disc (15), the insertion block (20) located at one end of the connecting rod (17) is inserted into the insertion groove (24), the ball ring (19) is used for driving the sliding sleeve (14) to move towards the right side, so that the fifth gear disc (22) is displaced into the idle rotation groove (23), the transmission force of the servo motor (18) is transmitted to the third gear disc (12) through the connecting rod (17), the screw rod mechanism (7) is further transmitted through the second gear disc (11) and the first gear disc (10), the process of retracting the cutter is accelerated, and the processing speed is accelerated.
