The synchronous control drive device shown in fig. 1 to 7 includes a first rotating mechanism 10, a second rotating mechanism 20, a traverse drive mechanism 30, and a main drive mechanism 40, wherein:

the first rotating mechanism 10 comprises a first rotating wheel 11 and a rotating shaft 12 fixed on the axle center of the first rotating wheel 11, and the rotating shaft 12 extends along the axial direction of the first rotating wheel 11; in the embodiment of the present disclosure, the rotating shaft 12 is fixedly connected to the first rotating wheel 11, and the rotating shaft 12 rotates synchronously with the first rotating wheel 11;

the second rotating mechanisms 20 are arranged at two sides of the first rotating wheel 11, each of the second rotating mechanisms 20 comprises a second rotating wheel 21 and a sleeve 22 connected with the second rotating wheel 21, the second rotating wheels 21 can be sleeved on the rotating shaft 12 in a relatively rotatable manner, the sleeves 22 and the rotating shaft 12 are coaxially arranged, and a first nut seat 23 is coaxially fixed at the free end of each sleeve 22; it should be noted here that, as shown in fig. 3, the length of the sleeve 22 is greater than the distance that the rotating shaft 12 extends in the axial direction of the first rotating wheel 11, i.e. the sleeve 22 is sleeved on the rotating shaft 12, so that the sleeve 22 rotates synchronously with the second rotating wheel 21; by the arrangement, a first runner 11 rotating synchronously with the rotating shaft 12 at the inner part and a second runner 21 rotating synchronously with the sleeve 22 at the outer part are formed;

the transverse moving driving mechanism 30 is arranged outside the second rotating mechanism 20, a first screw rod 31 is rotatably connected to the transverse moving driving mechanism 30, the first screw rod 31 extends into the sleeve 22, the first screw rod 31 is in threaded connection with the first nut seat 23, and one end of the first screw rod 31, which faces the end part of the rotating shaft 12, is provided with a sliding key connecting piece 24, and the sliding key connecting piece 24 is configured to be relatively slidably connected with the rotating shaft 12 only in the axial direction; referring to fig. 2 and 3, according to the conventional understanding, when the first nut seat 23 engaged with the first lead screw 31 rotates relatively, the first nut moves in the axial direction of the first lead screw 31, however, in the embodiment of the present disclosure, when the first lead screw 31 and the first nut seat 23 are fixed in the axial direction, the first lead screw 31 drives the first nut seat 23 to rotate synchronously under the circumferential force of the screw thread;

the main driving mechanism 40 is connected with any one sleeve 22 on the two second rotating mechanisms 20 and is used for driving the sleeve 22 to rotate; with this arrangement, since the first lead screw 31 is connected to the rotating shaft 12 at the inside and is meshed with the first nut seat 23 at the outside, when the sleeve 22 connected to the first nut seat 23 is rotated by an external force, the sleeve 22 drives the second rotating wheel 21 to rotate and also drives the rotating shaft 12 connected to the first lead screw 31 to rotate the first rotating wheel 11;

referring to fig. 2, when the traverse driving mechanism 30 drives the first lead screw 31 to move closer to or away from the rotating shaft 12, the synchronous rotation state of the second wheel 21 and the first wheel 11 is changed. Due to the fact that the first screw rod 31 is meshed with the first nut seat 23 through threads, when the first screw rod 31 moves along the axial direction of the first nut seat 23, the nut seat 23 can rotate under the action of the threads, and thus the synchronous rotation state between the first screw rod 31 and the first nut seat 23 can be changed, for example, when the first screw rod 31 moves towards one axial direction, the first nut seat 23 and the screw rod 31 rotate relatively, so that the first nut seat 23 drives the second rotating wheel 21 to rotate relative to the first rotating wheel 11, and the synchronous rotation state between the first rotating wheel 11 and the second rotating wheel 21 is changed;

in the above embodiment, the first rotating wheel 11 and the second rotating wheel 21 are connected through the screw rod 31 and the nut seat 23, and the change of the synchronous rotation state between the first rotating wheel 11 and the second rotating wheel 21 is realized by changing the relative rotation angle between the screw rod 31 and the nut seat 23, compared with the related art, only one main driving mechanism 40 is needed to control the three rotating wheels to synchronously rotate, when the rotation state between the first rotating wheel 11 and the second rotating wheel 21 needs to be changed, only the transverse movement of the first screw rod 31 is needed to be driven by the transverse movement driving mechanism 30, so that the synchronous rotation precision is higher, and the adjustment is more accurate.

On the basis of the above embodiment, as shown in fig. 4, the first bearings 13 are fixed to the rotating shaft 12 on both sides of the first runner 11, and the second runner 21 is fixed to the first bearings 13. The coaxiality of the second rotating wheel 21 and the first rotating wheel 11 can be ensured, the friction force is reduced, and the rotating noise is reduced by arranging the first bearing 13;

It should be noted that, in the embodiment of the present disclosure, the bearing seat 14 is fixed on the bottom plate, and through the arrangement of the bearing seat 14, a bearing mechanism for the rotation of the first rotating wheel 11 and the second rotating wheel 21 is provided, and it can be ensured that the position of the sleeve 22 is not moved when the first screw 31 moves in the axial direction;

in the embodiment of the present disclosure, the key point of driving the rotating shaft 12 to rotate while achieving the movement of the first lead screw 31 is the sliding key connecting piece 24, as shown in fig. 5, one end of the sliding key connecting piece 24 facing the rotating shaft 12 has a sliding slot 24a arranged along the axial direction, the end of the rotating shaft 12 has a non-circular insertion block 12a extending into the sliding slot 24a, and the insertion block 12a is arranged in the sliding slot 24a in a slidable manner along the axial direction and is used for driving the sliding key connecting piece 24 to rotate. Therefore, through the arrangement of the sliding groove 24a and the insertion block 12a, the effect that the sliding block can slide along the axial direction and can drive the rotating shaft 12 to rotate is achieved; it should be noted that the connection between the sliding key connector 24 and the rotating shaft 12 in the embodiment of the present disclosure has various forms, and is not limited to the flat slot structure shown in fig. 5, and may also be a cross-shaped structure as shown in fig. 6, or a spline connection structure, as long as the section of the matching section of the sliding slot 24a and the insertion block 12a is non-circular, which can achieve the above functions and all fall within the protection scope of the present disclosure.
