3) this control cable is closely arranged between each heart yearn when the split conductor stranding, and greatly degree has limited reversing of this control cable.
The utility model content
The purpose of this utility model is to provide a kind of robot arm control cable, this control cable is by increasing high-strength and high-modulus type polyethylene fibre silk in conductor, in control cable, increase the polypropylene fibre line, and optimization heart yearn laying up pitch and structural arrangement, thereby make this control cable have good bendability and mechanicalness, and its long service life.
The utility model is achieved in that
A kind of robot arm control cable comprises conductor, insulating barrier and oversheath; Described control cable also comprises high-strength and high-modulus type polyethylene fibre silk, polypropylene fibre line, sheath and separator, described conductor adopts the ultra-fine bare copper wire of the thin strand of multiply, many high-strength and high-modulus type polyethylene fibre silks kink with the ultra-fine bare copper wire of the thin strand of multiply is in the same place, high-strength and high-modulus type polyethylene fibre silk after kinking and the outside extruded insulation layer of the ultra-fine bare copper wire of thin strand form a core lead, polypropylene fibre line outside is extruded with sheath, and some core leads are formed outside, a branch of back with the outside polypropylene fibre line that is extruded with sheath and are extruded with control cable of separator and oversheath formation more successively.
Described many high-strength and high-modulus type polyethylene fibre silks are arranged on the conductor middle part, and the diameter of high-strength and high-modulus type polyethylene fibre silk is less than the diameter of the ultra-fine bare copper wire of thin strand.
Be provided with a polypropylene fibre line in the described control cable, some core leads are centered around the polypropylene fibre line outside that the outside is extruded with sheath, and consistent on polypropylene fibre line and the conductor length direction.
Described outside is extruded with the radius of polypropylene fibre line of sheath greater than the radius of lead, and has the gap between some core leads.
The material of described sheath is complete poly-fluorine ester.
The material of described separator is a cable paper.
Described oversheath is the poly-full fluorine ester oversheath of inferior face.
The utility model conductor adopts the ultra-fine bare copper wire of the thin strand of multiply, and has increased high-strength and high-modulus type polyethylene fibre silk at the conductor middle part, and the pliability that has promptly increased control cable has increased intensity again.Also increased the outside polypropylene fibre line that is extruded with sheath in the control cable, the polypropylene fibre line has high strength, corrosion-resistant and anti abrasive characteristics, plays the effect of strengthening filling.The polypropylene fibre line that is extruded with sheath with the outside after some core lead layering twistings is formed a branch of, and the outside is extruded with separator again and oversheath forms a control cable.During some core lead strandings, the polypropylene fibre line of centre is filled suitably amplification, have a little gap, simultaneously laying up pitch is amplified as far as possible thereby make between the outer heart yearn of arranging, with this windup-degree that increases control cable, robot arm can be reversed to freedom and flexibility.The utlity model has good bendability and mechanicalness, and its long service life.
