Industrial flexible cable

Abstract

The invention discloses an industrial flexible cable, relating to the technical field of cable manufacturing. The industrial flexible cable comprises a sheath layer and a plurality of cores disposed in the sheath layer, the sheath layer is internally provided with an elastic filling strip in the length direction of the cable and coaxially with the cable, the section of the elastic filling strip ispolygonal, each side thereof is recessed inwardly, the sides and the inner side wall of the sheath layer form a putting channel configured to put the cable cores; the corner angle of the elastic filling strip is butted against the inner side wall of the sheath layer; and the elastic filling strip is spirally disposed about the axis thereof. The cable is internally provided with the elastic filling strip, when the cable cores in the sheath layer are suffered from tension or the torsional force, the cable core can be retracted towards the axis of the sheath layer, namely the elastic filling strip is compressed, and the elastic filling strip itself can be retracted towards itself, so that the tension or the torsional force of the cable cores can be converted to the part of displacement of the cable core itself to avoid damaging.

Description

technical field [0001] The present invention relates to the technical field of cable manufacturing, more specifically, it relates to an industrial flexible cable. Background technique [0002] Industrial robots are multi-joint manipulators or multi-degree-of-freedom machine devices for the industrial field. Robot cables are the "blood vessels" and "nerves" of robots, and are important parts of robots. During the operation of industrial robots, there will be reciprocating relative motions at various angles between the joint manipulators. This puts high demands on the torsional performance of the cables between the joint manipulators. Special cables for robots with high flexibility, bending resistance, torsion resistance and long service life will surely become the first-choice cables for first-class machinery and mechanical equipment manufacturers at home and abroad. [0003] In order to improve the anti-torsion performance of the existing robot cables, the cables themselve...

AI Technical Summary

Problems solved by technology

[0004] During the use of industrial robot cables, they will not only be subjected to tensile force, but also torsion force. The above-mentioned stretching and torsion operations will cause damage to the cable surface and internal core. Damage to the cable surface will affect the safety of industrial robots. and reliability, and once the inner core of the cable is damaged, the industrial robot will fail or even stop
