Mechanical arm torsion cable

Abstract

The invention provides a mechanical arm torsion cable. The mechanical arm torsion cable has good torsion performance and high anti-fatigue capability, and has the characteristic that a core wire cannot be broken after the mechanical arm torsion cable is bended for several million times; and thus, long-term high-efficiency steady operation of a mechanical arm can be ensured. The mechanical arm torsion cable comprises an outer jacket layer and a covering layer, which are sequentially arranged from outside to inside, and have circular cross sections; a plurality of sets of signal wires and a plurality of cotton thread structures are arranged in the cavity of the covering layer; the signal wires are combined and annularly arranged in the centre of the cavity of the covering layer; the adjacent signal wires are appressed to each other; the outer walls of the signal wires are appressed to the inner wall of the covering layer; and the cotton thread structures are arranged in the cavity among the signal wires and the covering layer.

Description

technical field [0001] The invention relates to the technical field of cable structures, in particular to a mechanical arm twisting cable. Background technique [0002] In recent years, my country's mechanical arm torsion cable industry has developed rapidly, and its market position has gradually improved. As an important part of the automation field, the twisting cable of the mechanical arm has the vitality of the machine, and is suitable for connecting lines such as robotic equipment, mechanical arms, and CNC machine tools. The torsion of the cable makes the working life of the conventional cable short, and cannot guarantee the long-term efficient operation of the entire device. Contents of the invention [0003] In view of the above problems, the present invention provides a mechanical arm torsion cable, which has the characteristics of good torsion performance, strong fatigue resistance, and can undergo millions of times of bending without breaking the core wire, so a...
