Description

Bending-torsion-resistant cable for robot body

Technical Field

The utility model relates to the technical field of cables, especially, relate to a resistant crooked cable for twisting reverse robot body.

Background

The application of robots and mechanical arms is more and more extensive, the action frequency is more and more high, the robots are required, the mechanical arms are more and more flexible, and the uncertainty requirement of the action is more and more high. Therefore, the control cable and the signal transmission cable for the robot and the robot arm are required to have higher requirements and longer service life.

The bending and twisting performance of the existing cable for the robot is not ideal enough and needs to be further improved.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the not enough of prior art to a design science, practicality are strong, rational in infrastructure, fail safe nature is strong and crooked good resistant crooked cable for twisting robot body is provided.

In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the cable for the bending and twisting resistant robot body comprises a power wire core, wherein the cable core is formed by twisting the power wire core, a control wire core and a reinforcing core arranged in the center of the cable core; an outer sheath is extruded on the outermost layer of the cable core; and a shielding layer is arranged between the cable core and the outer sheath.

Based on the above, the reinforcing core is formed by extruding a high-strength insulating material, is placed at the center of the cable core, and has a protection effect on the power failure wire core in the cable bending process.

Based on the above, the power wire core and the control wire core are insulated by adopting a high-strength flexible insulating material and are extruded on the conductor in a pressurizing mode.

Based on the above, between reinforced core and the outer insulating core, all wrap a deck flexible band between adjacent two-layer insulating core and between shielding layer and the outer jacket.

Based on the above, the outer sheath adopts a wear-resistant, oil-resistant and UV-resistant elastomer.

Based on the above, the reinforcing core filler in the cable core is filled by the filling rod.

The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model discloses in strengthen the core and bear the most stress of cable core, the stress that the conductive core that significantly reduces bore at the crooked in-process of cable to the crooked life of extension cable. Between the outer and the insulation core of enhancement core, between every layer of insulation core, between cable core and the shielding, around the smooth band of package height softness between shielding and the sheath, be the cable and reduce the frictional force between each position at the torsion in-process, the torsion stress of insulation core when significantly reducing twists reverse to the life of extension cable. The bending torsion device has the advantages of scientific design, strong practicability, reasonable structure, strong safety and reliability and good bending torsion.

Fig. 1 is a schematic structural view of a cable for a bending and torsion resistant robot body according to the present invention.

Detailed Description

The cable for the bending and torsion resistant robot body shown in fig. 1 comprises a cable core, wherein the cable core is formed by twisting a power wire core 1, a control wire core 2 and a reinforcing core 3 arranged in the center of the cable core in the same direction. An outer sheath 8 is extruded on the outermost layer of the cable core; a shielding layer 7 is arranged between the cable core and the outer sheath; between restrictive coating 8 and shielding layer 7, between shielding layer 7 and the cable core, all wrap one deck band 4 around the reinforcing core 3 outside at cable core center between each layer of cable core and cable core, help reinforcing cable to reduce the friction between shielding layer and the oversheath in the process of twisting round. The number of the power wire cores is 9. The number of the control wire cores 2 is 8. The section of the power core conductor is 1.0mm²～6mm²The cross section of the conductor of the control wire core is 0.3mm²～1.5mm²。

Wherein, the filler of the reinforced core 3 is filled by a filling rod. The filling rod is formed by extruding high-strength insulating materials, plays a role in strengthening stress on bending of the cable, transfers the stress of the insulated wire core to the reinforced core, reduces the stress on the conductive wire core in the bending process of the cable, and prolongs the service life of the cable.

The outer insulating layers of the power wire core 1 and the control wire core 2 are made of materials with high strength, good toughness, smooth surfaces and good insulating property through extrusion, and when the cable is bent and twisted, the cable plays a role in protecting the conductor

The wrapping belt layer 4 between the layers is formed by wrapping a high-flexibility PTEF belt with the thickness of 0.05mm, and the PTEF belt has the characteristics of high temperature resistance, flexibility, high strength and smooth surface, so that the friction between the parts of the cable is reduced in the twisting process, the sliding between the layers is increased, the twisting angle of the wire core is reduced, the twisting stress generated by the wire core in the twisting process is reduced, and the service life of the cable in the using process is prolonged.

The utility model discloses the concrete application way is many, and the above-mentioned only is the preferred embodiment of the utility model, should point out, to ordinary skilled person in this technical field, under the prerequisite that does not deviate from the utility model discloses the principle, can also make a plurality of improvements, and these improvements also should be regarded as the utility model discloses a scope of protection.
