Description

Mechanical arm cable

Technical field

The utility model relates to cable, in particular to a kind of mechanical arm cable.

Background technique

With the disappearance of China human mortality bonus, there is shortage in labour, and manufacturing enterprise constantly increases machine Man's Demands. Chinese Government releases a series of incentive measures, pushes the investment to Robot industry.Robot development is mainly manifested in: height Emulation, featured function and integrated service.Wherein realize that " featured function " demand in development is particularly important.This respect is most common It is exactly various mechanical arms, they are also the highest robot of the frequency of occurrences in robot conference exhibition room: the mechanical arm having is assembling Automobile, some is in sorting courier packages, and some in simulation laparoscopic surgery, taken pen and drawn a picture writing by mechanical arm also, These functional robots are the strong impetus of development of modern industry.

But since mechanical arm can move repeatedly at work, so that cable reversed torsion, folding on mechanical arm, are easy Lead to cable skin rupture etc., there is some potential safety problems.

Utility model content

The purpose of this utility model is to provide a kind of mechanical arm cables, have the advantages that be less prone to skin breakage.

The above-mentioned technical purpose of the utility model has the technical scheme that a kind of mechanical arm electricity consumption Cable, including cable core and covering, the covering include Kapton wrapping layer, tincopper fuse wire braided armor, TPE from inside to outside Layer, the first protective layer of PUR reinforce stratum reticulare and the second protective layer of PUR, and first protective layer of PUR reinforces stratum reticulare and PUR second Protective layer is combined with each other.

Through the above technical solutions, PUR toughness with elasticity is good, it is wear-resisting, resist cold, water-fast, ageing-resistant, acid and alkali-resistance, weatherability, Long service life, many excellent functions such as uvioresistant and energy release, therefore at work, pass through outermost PUR First protective layer and the second protective layer of PUR can make cable be not likely to produce the situation of covering breakage when in use, simultaneously because It is compounded with reinforcement stratum reticulare between the second protective layer of the first protective layer of PUR and PUR, therefore PUR the can be made by reinforcing mat One protective layer is stronger when in use with the second protective layer of PUR and is not easily broken, even if the first protective layer of PUR and PUR second There is slight crack in protective layer, makes slight crack be not easy to open and expand under the action of reinforcing mat, security risk is effectively reduced.And polyamides Imines film chemical property is stablized, and Kapton does not need addition fire retardant and prevents from burning, therefore at work The cable also has certain flame retardant property, and when use is more safe and reliable.

Preferably, aromatic nylon layer is coated with outside second protective layer of PUR.

Through the above technical solutions, cable has higher resistance to after being coated with aromatic nylon layer outside the second protective layer of PUR Hot (300 ~ 500 " C).Cable is worked in hot environment, such cable when working mechanical arm in high -temperature workshop It can guarantee the safe and reliable work of mechanical arm.

Preferably, the reinforcement stratum reticulare is Kev seine.

Through the above technical solutions, Kevlar line density is low, intensity is high, good toughness, high temperature resistant, easy to process and molding, Its intensity is 5 times of equal quality steel, but density is only 1/5th of steel, and material tough and hard wear resistant is tempered toughness with gentleness, so that Cable will not be broken by larger pulling force in use, while can also guarantee that cable is preferably flexible, and reinforcing mat exists The first protective layer of PUR and PUR the second protective layer intensity can be made to increase between the second protective layer of the first protective layer of PUR and PUR, Effectively avoiding the first protective layer of PUR and the second protective layer of PUR, there is a situation where breakages, and the first protective layer of PUR and PUR second are protected Sheath will be connected with each other by the mesh reinforced on stratum reticulare, so that the first protective layer of PUR and the second protective layer of PUR are when in use not Easily there is a phenomenon where being layered, enhancing work will constantly be played to the first protective layer of PUR and the second protective layer of PUR by reinforcing stratum reticulare at this time With.

Preferably, the cable core includes power supply line and control line and reinforcing rib, and the control line and power supply line, which surround, to be added Strengthening tendons setting, and the reinforcing rib is located at the center of cable core.

Through the above technical solutions, cable strength can be made to increase, avoiding cable, there is a situation where be broken in tension Occur.

Preferably, polyester yarn fiber is filled between the covering and cable core.

Through the above technical solutions, polyester yarn fiber heat resistance is high;Stretching resistance is strong;The resistance to various chemistry such as acidproof, alkaline-resisting are rotten Erosion;With against weather, dust-proof, antistatic, antiultraviolet;It is non-toxic and tasteless durable, fire-retardant.Service life can reach 15 years with On, being filled between covering and cable core can play a very good protection to cable core, while can also play the work of isolation heat With, and the fire-retardant effect for avoiding cable core burning impaired is played when there is fire.

Preferably, the power supply line and control line quantity are two, and two control lines and two power supply lines are located at square At four angles of shape, control line be located at two of rectangle it is diagonal on, power supply line be located at another group of rectangle it is diagonal on.

Through the above technical solutions, at this time the distance between two power supply lines and the distance between two control lines compared with Greatly, be not susceptible to the case where two power supply lines mutually leak electricity, at the same between control line distance it is larger both avoid generating signal it is dry It disturbs.

Preferably, locating piece is provided between the control line and neighboring power wires.

Through the above technical solutions, cable, in production, being easy to appear control line, power supply line, position distribution is not in covering Uniform situation can limit the relative position of power supply line and control line by locating piece, it is ensured that power supply line and control when production Line is uniformly distributed in each position of cable, part cable core performance occurs when avoiding the occurrence of power supply line or control line position unevenness Bad situation.

Preferably, the locating piece includes fixed the first locating piece on the power line and fixed second on the control line Locating piece, first locating piece are provided with protrusion towards the second locating piece end, are provided on second locating piece and protrusion The slot of cooperation.

Through the above technical solutions, using when the first locating piece and the second locating piece be docking together, later will be raised It is inserted into slot, fixes the relative position between power supply line and control line, it later can be in power supply line and control line Outer package covering, during fabrication, power supply line and control line relative position are uniform, cable use when performance more preferably.

In conclusion the utility model having the beneficial effect that in contrast to the prior art

(1) cable strength is higher, and cable is also not easy to be pulled off when by compared with strong pulling force；

(2) cable has preferable fire retardancy, and covering is not susceptible to breakage to cable when in use, and when use more pacifies Entirely.
