Detailed Description

Example (b): the utility model provides a welding robot uses electric wire, includes trachea 1, conductive layer and protection skin, 1 inside air current channel who supplies the gas circulation that forms of trachea, the conductive layer cladding of making by electrically conductive material is in 1 outside of trachea, and the outer cladding of protection that insulating material made is in the conductive layer outside.

The air pipe 1 and the power line of the welding robot are compounded in the same cable through the electric wire, the service life of the air pipe 1 and the service life of the power line are guaranteed simultaneously, the installation space is greatly saved, and the installation speed is improved.

The air pipe 1 is a polyurethane air pipe 1. Adopt polyurethane material preparation trachea 1, intensity is high, and is not fragile, trachea 1 will detect resistant number of times of buckling before assembling, and fixed number of times can not ftracture and produce the crease.

The conductor layer comprises 6 or 18 strands of anaerobic copper wires 2, and the 6 or 18 strands of anaerobic copper wires 2 are wound outside the trachea 1.

Each strand of the oxygen-free copper wire 2 is wound outside the air pipe 1 at a pitch of 10-12 times of the finished outer diameter (finished outer diameter: the total outer diameter of each strand of the copper wire after being wound on the air pipe 1).

Each strand of anaerobic copper wire 2 is composed of a single extremely fine anaerobic copper wire 2 with the diameter of 0.08 +/-0.008 mm formed by at least two times of composite twisting.

A plurality of bulletproof wires 3 are added at the center of each strand of anaerobic copper wire 2. The anti-stretch wire 3 has super-strong tensile property and heat resistance as the name suggests, so that the wire can ensure the normal current stable transmission of the conductor, the anti-stretch and anti-twist anti-fatigue characteristics of the conductor can be greatly improved, and the situation that the conductor is broken in the operation of a robot is avoided.

And cotton wires 4 are added between the strands of anaerobic copper wires 2 of the conductor layer. Add cotton thread 4 and can strengthen the conductor layer bulk strength, under bearing pulling force pulling action, cotton thread 4 at first bears the pulling force effect, and then avoid each strand of anaerobic copper wire 2 to take place the internal contraction because of bearing great pulling force effect, can protect each strand of anaerobic copper wire 2 not pulled the fracture, cotton can also protect the conductor can not take place the displacement in the operation of random robot, so that looks mutual friction between the conductor causes the conductor to take place the fracture, through the packing to the gap between the conductor, whole electric wire can be more round and more complete on the structure, the outward appearance is more pleasing to the eye.

The cotton thread 4 and each strand of anaerobic copper wire 2 are alternately arranged and wound outside the air pipe 1.

The outer layer of protection includes non-woven fabrics layer 5 and ectoderm 6, non-woven fabrics layer 5 winding cladding is in the conductor layer outside, and ectoderm 6 is extruded in the non-woven fabrics layer 5 outside.

The outer skin layer 6 is a high-polymerization degree PVC skin. The PVC sheath with ultrahigh polymerization degree is adopted for coating, so that the environment-friendly effect is good, and the mechanical strength and the fatigue resistance are high.
