Embodiment Construction

[0025] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0026] Such as Figure 1 to Figure 4 As shown, a hollow cable protection structure for an industrial robot includes a motor base 3 and a hollow reducer 2 connected to the motor base 3 by screws. The output end of the hollow reducer 2 is connected to a wrist body 1 and a hollow shaft drive The end is connected with a drive pulley 5, and also includes a hollow wire sleeve 4 installed at both ends in the seam of the wrist body 1 and on the drive pulley 5, a T-shaped wire sleeve 7 connected to the motor base 3, and a A robot cable 8 with a hollow wire guide 4 and a T-shaped wire guide 7 bound on the T-shaped wire guide 7 by a cable tie.

[0027] Both the hollow wire-passing sleeve 4 and the T-shaped wire-passing sleeve 7 are coaxial with the hollow shaft of the hollow reducer 2 .

Abstract

The invention relates to an industrial robot hollow cable protection structure. The industrial robot hollow cable protection structure comprises a motor base and a hollow speed reducer; an output endof the hollow speed reducer is connected with a wrist body; and a hollow shaft driving end is connected with a driving belt wheel. The industrial robot hollow cable protection structure further comprises a hollow wire passing sleeve whose two ends are mounted in a stop port of the wrist body and on the driving belt wheel, a T-shaped wire passing sleeve connected to the motor base, and a robot cable penetrating through the hollow wire passing sleeve and the T-shaped wire passing sleeve and bound on the T-shaped wire passing sleeve through a binding belt. The industrial robot hollow cable protection structure can guarantee concentricity of the wire passing sleeves and the speed reducer to prevent wear of the hollow wire passing sleeve, and can prevent deflection of cables to reduce direct contact between the cables and the hollow wire passing sleeve to achieve secondary protection effect, so that the service life of the cables is effectively prolonged, the reliability of the cables is greatly improved, the robot stability is guaranteed, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the technical field of built-in routing of industrial robots, in particular to a hollow cable protection structure for industrial robots. Background technique [0002] At present, for small-load robots, the cables are usually built into the body, and the condition of the robot cables directly affects whether the robot body can run stably. For hollow cable routing, the cable needs to pass through the high-speed hollow shaft. If the cable is in direct contact with the high-speed hollow shaft, the internal cable of the reducer is prone to wear when the reducer is running. When the cable is worn to a certain extent At this time, the robot will stop or even be in danger, resulting in high maintenance costs. In order to solve this problem, domestic and foreign robot manufacturers mostly improve the wear and tear of the cables by applying grease to the surface of the cables, or by adding wire sleeves. [0003] However, when the wire...
