[0026] Working principle:
[0027] The utility model discloses a drive device one 8 (generally motor) is opened to the front bracket 9 of being placed between two clamping plates 2 is driven by the bidirectional screw rod 6, and because the bidirectional screw rod 6 is provided with two opposite threads, and two sliding blocks one 7 are provided with the thread hole matched with the two threads on the bidirectional screw rod 6, therefore under the rotation of bidirectional screw rod 6, because the sliding hole of two sliding blocks one 7 is all set on the sliding limit rod 5 and prevents the limit of rotation, the rotation of bidirectional screw rod 6 is converted into the linear motion of two sliding blocks one 7 relative close, and two clamping plates 2 fixedly connected with two sliding blocks one 7 will be close to the movement simultaneously, and the other end of two clamping plates 2 will be along with two sliding blocks two 10 follow the movement of the support rod two 13 with sliding slot, until two clamping plates 2 clamp the both ends of front bracket 9, that is, the horizontal positioning of front bracket 9 is carried out.
[0028] Then, the upper surface of the front bracket 9 is abutted with the longitudinal clamping protrusion 14, and the sliding support 16 in the sliding hole 15 is adjusted, so that the longitudinal clamping plate 17 abuts against the lower surface of the front bracket 9. (Generally, the upper surface of the front bracket 9 is basically on the same horizontal plane, so no additional active adjustment is needed, and the lower surface of the front bracket 9 is generally uneven, because active adjustment is needed.) Then, the longitudinal clamping plate 17 is locked by the locking assembly 18, so that the longitudinal positioning of the front bracket 9 is realized, and at this time, punching and slotting processing can be carried out.
[0029] When one side of the front bracket 9 is processed, and the other side of the front bracket 9 needs to be processed, the driving motor two 12 is started, the driving motor two 12 drives the transmission gear 22 through the driving gear 21, and the transmission gear 22 drives the rotating installation part 20 to rotate, so that the rotating installation part 20 drives the support rod one 4 with sliding slot, the support rod two 13 with sliding slot, the two clamping plates 2 and the front bracket 9 to rotate by 180 degrees, until the support rod two 13 with sliding slot is nested in the other movable slot 11, and the overturning process is completed.
