Detailed Description
Referring to fig. 1 and 2, the steel wire transmission device provided in this embodiment includes a rotating shaft 1, two ends of the rotating shaft 1 are respectively erected on a supporting assembly, a first end of the rotating shaft 1 is connected to a rotation driving assembly (not shown in the drawings), a second end of the rotating shaft 1 is coaxially provided with a guide cylinder 3, the guide cylinder 3 is fixedly mounted on the supporting assembly, and an inner side surface of the guide cylinder 3 is provided with an internal thread; a rotating piece 4 is coaxially sleeved on the outer side surface of the rotating shaft 1 close to the first end, a guide groove 11 is formed in the outer side surface of the rotating shaft 1 along the length direction of the rotating shaft, and a sliding table (not shown in the figure) matched with the guide groove 11 is arranged on the rotating piece 4; a driving piece 5 and a roller 6 are sequentially coaxially sleeved on the outer side surface of the rotating piece 4, an accommodating cavity for accommodating the guide cylinder 3 is formed between the driving piece 5 and the roller 6, and an external thread meshed with the internal thread of the guide cylinder 3 is arranged on the outer side surface of the driving piece 5; the outer side of the drum 6 is wound with steel wires (not shown in the figure).
It should be noted that when the rotary driving assembly drives the rotating shaft 1 to rotate, the rotating member 4 mounted on the rotating shaft 1 rotates synchronously with the rotating shaft 1. Meanwhile, the driving part 5 and the roller 6 which are arranged on the rotating part 4 synchronously rotate along with the rotating part 4, at the moment, the guide cylinder 3 is fixedly arranged on the supporting component, the guide cylinder 3 is accommodated in an accommodating cavity formed between the driving part 5 and the roller 6, and the internal thread of the guide cylinder 3 is meshed with the external thread of the driving part 5, so that the driving part 5 can drive the roller 6 and the rotating part 4 to move along the axial direction of the guide cylinder 3 (the rotating shaft 1) under the effects of meshing of thread structures and autorotation of the driving part. Because the rotating part 4 is connected with the rotating shaft 1 through the guide groove 11 and the sliding table, the rotating part 4, the driving part 5 and the roller 6 can be ensured to stably move along the length direction of the rotating shaft 1 while rotating. And then the rotation of the rotating part 4, the driving part 5 and the roller 6 can be realized by the positive and negative rotation of the driving motor, and the reciprocating linear motion is carried out along the length direction of the rotating shaft 1 at the same time of the rotation, so that the rotating motion of the motor is converted into the linear motion. Therefore, the steel wire wound on the outer side surface of the roller 6 is externally connected with a roller, so that the steel wire can reciprocate around the outer side surface of the roller 6, and meanwhile, the roller 6 can do linear motion while rotating, so that the steel wire can always reciprocate on the same straight line, and the transmission stability is ensured.
