Embodiment Construction

[0025] see Figure 1-Figure 10 Explain, a two-way drive mechanism for wire-driven flexible body, which includes a housing 1, a wire reel 3, a fixing member 2 and a drive wire 4;

[0026] Two circles of wire grooves 31 are processed on the outer peripheral surface of the wire reel 3, and two sections of arc-shaped gaps 11 are provided on the peripheral side of the casing 1. The casing 1 is set on the wire disk 3, and the gaps 11 correspond to the wire grooves 31. A fixing hole 32 is opened, and the fixing member 2 is installed in the fixing hole 32 for fixing one end of the driving wire 4 wound in the wire groove 31 , and the other end of the driving wire 4 is drawn out from the gap 11 .

[0027] In the above-mentioned embodiment, both the wire reel 3 and the housing 1 have a circular structure, and in a possible embodiment, the driving wire 4 is a steel wire or a steel wire rope or a flexible rope. Easy to use and reliable. During the rotation process of the wire reel 3, the...

Abstract

A bidirectional driving mechanism for wire-driven flexible body relates to a driving device, which comprises a casing, a wire drum, a fixing piece and a driving wire; Two arc-shaped gaps are opened, the shell is sleeved on the wire reel, the gap corresponds to the wire groove, the wire groove is provided with a fixing hole, and the fixing piece is installed in the fixing hole to fix one end of the driving wire wound in the wire groove, and the driving The other end of the wire is drawn out of the slit. The invention has reliable operation, controllable operation and simple structure.

Description

technical field [0001] The invention relates to a driving device, in particular to a single-degree-of-freedom bidirectional driving mechanism for wire-driven flexible bodies. Background technique [0002] At present, for wire-driven flexible bodies, the same degree of freedom uses two tension wires for coordinated driving, and how to ensure the coordinated movement of the two driving wires during the movement is a crucial part to ensure the normal operation of the flexible body. The current existing drive mainly adopts servo synergy, and each wire is equipped with a set of servo drive system. This structure increases the number of motors and actuators. At the same time, the cumulative error of transmission is inaccurate, which makes it difficult to balance both ends and reduces reliability. . Contents of the invention [0003] The present invention aims to overcome the deficiencies of the prior art and provide a bidirectional drive mechanism for silk-driven flexible bodie...
