Description

Anti-torsion mechanical arm cable

Technical field

The utility model relates to robot cable technologies, and in particular to a kind of anti-torsion mechanical arm cable.

Background technique

To realize the work such as assembly, sorting, welding, cutting under compound action, it is necessary to which robot arm is in multiple axis Between have bending, torsion ability.And it is particularly important in the wire and cable that robot interior provides power and control signal.

It is mostly currently on the market flexible cable for the cable of robot arm, this kind of cable on material although select soft Property preferable material, be designed for the particularity of robot arm movement although more soft, cable by Under the influence of the mechanical forces such as extruding, stretching, curling caused by bending and torsion, core will soon occur plays torsion or disconnected Line causes periods of robot operation stop, has seriously affected production efficiency and reliability.

Utility model content

(1) the technical issues of solving

In view of the deficiencies of the prior art, the utility model provides a kind of anti-torsion mechanical arm cable, to solve tradition Cable the problem of being unable to satisfy harness axial bending deformation demand in mechanical arm.

(2) technical solution

In order to achieve the above object, the utility model is achieved by the following technical programs:

A kind of anti-torsion mechanical arm cable, including core, thermoplastic elastomer obturator and oversheath, the core row It is listed in around thermoplastic elastomer obturator and in outer layer covers by oversheath, the oversheath is equipped with axially distributed cross Slot, the translot equidistantly distributed around oversheath, between the translot around oversheath be equipped with cannelure, the cannelure with The setting of translot vertical interlaced.

More preferred, the core quantity is 4 and is distributed in around thermoplastic elastomer obturator in rectangle quadrangle.

It is more preferred, the band and shaping cover being distributed from inside to outside are equipped between the core and oversheath, it is described fixed Jacket is circle.

More preferred, the band is transparent plastic film.

More preferred, the shaping cover is polypropylene material.

(3) beneficial effect

The utility model embodiment provides a kind of anti-torsion mechanical arm cable.Have it is following the utility model has the advantages that

Core is to be divided into four groups and enclose stranding in rectangular arranged one on the outside of obturator, and be fixed with band, then benefit With the shaping cover of outer circular, ensure that has gap between positioning sleeve and core, can again cable bend when, have in inside Buffer function meets the state of cable high speed reciprocating motion, can effectively avoid on cable core if there is core can be bent The case where stress breaks in the process；It selects high-intensitive oversheath and external structure is improved, be additionally arranged translot and cannelure, make Cable, which may be implemented in outside when multi-angle is bent between multiple axis, to be had radial and axial spacious amount and is unlikely to break.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor Under, it is also possible to obtain other drawings based on these drawings.

Fig. 1 is mechanical arm cable cross-sectional view；

Fig. 2 is mechanical arm cable schematic surface.

Appended drawing reference: 1, core；2, thermoplastic elastomer obturator；3, oversheath；4, translot；5, cannelure；6, band；7, fixed Jacket.

Specific embodiment

It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Based on the implementation in the utility model Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to The range of the utility model protection.

With reference to the accompanying drawing and 1 and following examples elaborate the technical program content:

Embodiment 1

As shown in Figs. 1-2, a kind of anti-torsion mechanical arm cable, including core 1, thermoplastic elastomer obturator 2 and outer Sheath 3, core 1 are arranged in around thermoplastic elastomer obturator 2 and in outer layer covers by oversheath 3, and oversheath 3 is equipped with edge The translot 4 being axially distributed, 4 equidistantly distributed of translot are equipped with cannelure 5 around oversheath 3 around oversheath 3 between translot 4, Cannelure 5 and 4 vertical interlaced of translot are arranged.It selects high-intensitive oversheath and external structure is improved, translot 4 is additionally arranged and is indulged Slot 5, so that cable is may be implemented in outside when multi-angle is bent between multiple axis has radial and axial spacious amount and is unlikely to break

Embodiment 2

The present embodiment the difference from embodiment 1 is that, as shown in Figure 1,1 quantity of core be 4 and in rectangle quadrangle be distributed Around thermoplastic elastomer obturator 2, the setting of the arrangement mode can be mainly on cable axis to avoid core, prevent line There is the axial bending of wide-angle, (remoter apart from axial line when bending, deformation amplitude is smaller) in cable, therefore can extend cable Service life, be especially suitable for this frequent movement of mechanical arm harness demand.

Embodiment 3

The present embodiment the difference from example 2 is that, as shown in Figure 1, between core 1 and oversheath 3 be equipped with from inside to outside The band 6 and shaping cover 7 of distribution, the effect of band are to play four cores fixed effect of binding, and shaping cover 7 is circle The reason of then mainly for guarantee between core and shaping cover, there are gaps.

In another embodiment, band 6 is transparent plastic film, and transparent plastic film is selected to occupy sky mainly for reducing Between, it is thinner under the conditions of can satisfy cable, it is especially suitable for small space wiring as mechanical arm.

In another embodiment, shaping cover 7 is polypropylene material, can also be square while selecting this material to be mainly in view of light Just shaping cover is installed.

The utility model has the advantages that

Core is to be divided into four groups and enclose stranding in rectangular arranged one on the outside of obturator, and be fixed with band, then benefit With the shaping cover of outer circular, ensure that has gap between positioning sleeve and core, can again cable bend when, have in inside Buffer function meets the state of cable high speed reciprocating motion, can effectively avoid on cable core if there is core can be bent The case where stress breaks in the process.
