Abstract

The utility model relates to a torsion-resistant robot cable. A main cable core is arranged in the center of an ETFE insulating layer. Seven torsional sheaths are rotatably distributed with the central axis of the main cable core as a centre in the ETFE insulating layer. Each torsional sheath comprises a bent basic strip body with an arc-shaped cross section. A side cable core is arranged between two cladding sheet bodies in each torsional sheath. A polyurethane foam body is loaded between two cladding sheet bodies in each torsional sheath. The torsion-resistant robot cable has a simple and clear hierarchical structure. Torsional sheaths are additionally arranged in a traditional cable structure. The gaps among the torsional sheaths and a separation sleeve can play certain buffering function when an outside force torque is borne. Decrease of fatigue strength and crack generation caused by repeated stress of the single entity is avoided. In addition, the loaded TPU buffer layers and polyurethane foam bodies can further play the flexible buffer function, and therefore the service life is prolonged.

A kind of resistance to torsion machine people cable

Technical field

The utility model relates to the technical field of cable, especially a kind of resistance to torsion machine people cable.

Background technology

In known technical field, Robotics was through the development of more than 20 years, day by day become the important manufacturing process of one in high-quality precision and sophisticated technology field in the industries such as machining manufacture, can substitute the operation etc. of manually carrying out repeated labor, hazardous environment, the development of microelectronics, sensor technology has also advanced seriation and the engineering application of industrial robot product.In actual application link, robot need to pass through cable power supply, reception/transmission instruction, needs traditional cable to possess the characteristics such as oil resistant, wear-resisting, acid and alkali-resistance, especially needs to possess certain flexibility, can bear bending force effect repeatedly, to adapt to the flexible operating of robot.

Utility model content

The technical problems to be solved in the utility model is: provide a kind of and possess that certain flexibility, endurance life are large, the resistance to torsion machine people cable of long service life.

The utility model solves the technical scheme that its technical problem adopts: a kind of resistance to torsion machine people cable, comprise the PV restrictive coating arranging in turn from outside to inside, nonwoven fabrics screen and ETFE insulating barrier, be provided with main push-towing rope core at the center of described ETFE insulating barrier, in described ETFE insulating barrier, and rotation is distributed with 7 and reverses sheath centered by the central axis of main push-towing rope core, described torsion sheath has the base bar body that cross section is circular arc bending, and described base bar body is concentric with main push-towing rope core, both sides at described base bar body are equipped with coated lamellar body, between two coated lamellar bodies in each torsion sheath, be equipped with side cable core, and be filled with polyurethane foam between two coated lamellar bodies in each torsion sheath, be coated with separation sleeve in described main push-towing rope core outside, between described separation sleeve and torsion sheath, be filled with TPU resilient coating, and one by one corresponding to the gap between adjacent two coated lamellar bodies, be provided with spacing preiection bar in the outside of described separation sleeve.

Further, as a kind of concrete execution mode, the utility model is wherein made as neutral ground cable by one in 7 side cable cores.

Further, as a kind of concrete version, the cable core of side described in the utility model is made up of 18 copper conductor twisteds, and described copper conductor cross-sectional area is 0.5～0.75mm ².

Further, as a kind of concrete version, the cross section of the bar of spacing preiection described in the utility model is half-circle-arc shape.

The beneficial effects of the utility model are: the utility model hierarchical structure is simply clear, in traditional construction of cable, set up torsion sheath, by reversing the gap between sheath and separation sleeve, can, in the time bearing external force moment of torsion, play certain cushioning effect, avoid single entity repeatedly stressed, thereby cause the decline of fatigue strength, the situation such as crack, simultaneously by TPU resilient coating and the polyurethane foam of filling, can further play the function of flexible buffer, thereby improve useful life.
