DETAILED DESCRIPTION

[0016] 1The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model.

[0017] In this embodiment, refer to Figs. 1-2The application discloses a wire bundle wire machine pay-off rack automatic clamping device, which comprises a pay-off shaft 1, a synchronous pulley 2 slidably sleeved on the pay-off shaft 1 and a clamping mechanism, a wire arranging disc 3 is sleeved on the outer part of the synchronous pulley 2, the right end of the pay-off shaft 1 is inserted into the clamping mechanism, a locking ring 7 is sleeved on the shaft rod of the pay-off shaft 1 close to the right end, and the locking ring 7 is fixedly connected with the right end surface of the synchronous pulley 2.

[0018] The two ends of the pay-off shaft 1 are provided with bearing seats 4 for supporting the pay-off shaft 1, and a motor 6 for driving the rotation of the pay-off shaft 1 is arranged outside the bearing seat 4 on the right side of the pay-off shaft 1. A supporting plate 5 is arranged on the right side of the pay-off shaft 1, and the motor 6 on the right side is fixed through the supporting plate 5. Through the driving of the motor 6, the pay-off shaft 1 is rotated, and finally the wire arranging disc 3 is used to realize the wire bundle operation.

[0019] The clamping mechanism is composed of a positioning end 8, a shaft sleeve 9, a bolt 10, a threaded sleeve 11 and a screw rod motor 12, wherein a through hole is formed in the end surface of the positioning end 8 facing the pay-off shaft 1, the shaft sleeve 9 is left in the through hole, the right end of the pay-off shaft 1 is inserted into the shaft sleeve 9, when the right end of the pay-off shaft 1 is completely inserted into the shaft sleeve 9, the positioning end 8 just abuts against the locking ring 7, the position of the locking ring 7 is limited by the positioning end 8, that is, the position of the synchronous pulley 2 is limited by the positioning end 8, and the position of the synchronous pulley 2 is ensured to be fixed.

[0020] The bolt 10 is rotationally connected to the end surface of the positioning end 8 away from the pay-off shaft 1, the threaded sleeve 11 is threadedly connected to the bolt 10, and the bolt 10 is connected to the output end of the screw rod motor 12. The screw rod motor 12 controls the rotation of the bolt 10, and further realizes the purpose of the threaded sleeve 11 moving back and forth on the bolt 10.

[0021] A plurality of connecting arms 13 are rotationally mounted on the outer circumferential surface of the threaded sleeve 11, a plurality of movable supports 14 are rotationally mounted on the outer circumferential surface of the positioning end 8, and the movable supports 14 are arranged in one-to-one correspondence with the connecting arms 13.

When the threaded sleeve 11 moves to the right, the connecting arm 13 will push the movable support 14, and finally realize the insertion of each positioning block 15 into the corresponding insertion hole of the locking ring 7, and finally fix the right end of the pay-off shaft 1 by using the positioning end 8 to maintain its position unchanged. When it is needed to disassemble the synchronous pulley 2, the threaded sleeve 11 moves to the left, the connecting arm 13 pulls the movable support 14 to separate the positioning block 15 from the insertion hole of the locking ring 7, and the positioning end 8 is in a separable state with the pay-off shaft 1, so that the clamping mechanism can be pulled out from the right end of the pay-off shaft 1, and the parallel wire disc 3 on the synchronous pulley 2 can be conveniently and quickly taken out. Finally, it needs to be supplemented that, in order to ensure that the pay-off stand is suspended and balanced, the left end of the clamping mechanism is provided with a disc which is the same height as the support plate 5 on the right side, and the screw motor 12 of the clamping mechanism is installed at the center of the disc.
