Description
Technical Field
[0001] The utility model relates to the technical field of robot wire-passing structures, and in particular discloses a conveniently installed anti-wear wire component for wire-passing inside a robot arm. Background Art
[0002] The wiring of the robot arm includes two types: external wiring and internal wiring. Among them, the robot with internal wiring is neat and beautiful, small in size, and suitable for many assembly production lines, but the internal wiring is difficult and has high requirements. In the prior art, the joint base components and the third joints of the robot with internal wiring mostly use "protective cover + twisted pair loose wire" or directly use "high flexibility with protective layer + lubricating oil". The first structure has high requirements for twisted pair and anti-interference, and the high-flexibility protective layer of the second structure is easy to wear, has a short life, and is troublesome to maintain in the later use. If other more complex forms are used, the line protection mechanism will be large and impractical.
[0003] Usually the wire harness inside the robot will be worn. If there is an abnormality in one axis, the robot will alarm and need to be rechecked and the wire harness replaced, which wastes a lot of time and affects the normal and stable operation of the robot.
[0004] Therefore, it is urgent to design a wire-passing structure and a robot to solve the problem of wire harness wear inside the robot. Utility Model Content

The utility model is provided with a fixing piece and a wire fixing ring, and has a compact structure, does not require additional lubricating oil to lubricate the wires, is convenient for fixing the wire group, reduces the risk of wear of the wire group, effectively improves the torsion reliability of the wire group, saves time and effort in wiring, is simple and convenient, and reduces the requirements for personnel's operating skills.
[0007] Furthermore, the wire fixing member includes a first plate portion, a second plate portion, and a bending portion connecting the first plate portion and the second plate portion, the bending portion is bent from the first plate portion, the second plate portion is bent from the bending portion, the first plate portion and the second plate portion are parallel, the first plate portion is connected to the joint body, and the threading hole is set on the second plate portion. By setting the bending portion, the curved arched part of the wire group corner is kept away from the inner hole of the reducer, thus solving the problem of the curved arched part of the wire group touching the rotating inner hole, effectively avoiding the wear of the wire group, and improving the reliability and safety of the line.
[0008] Furthermore, the first plate portion is provided with a through hole for installing bolts, and the first plate portion is fixedly connected to the joint body via the bolts, thereby improving the connection stability between the wire fixing member and the joint body and preventing the wire fixing member from shaking and wearing the wire group when the robot arm is in operation.
[0009] Furthermore, the number of the threading holes is two. Multiple groups of threading holes can be used to distinguish and bundle different types of wire groups, such as strong current, weak current, control signal, air pipe, etc., to facilitate identification, management and maintenance.
[0010] Furthermore, the wire fixing ring includes a cylindrical mounting portion and a limiting portion arranged at one end of the mounting portion, the limiting portion being protruded from the outer surface of the mounting portion; the mounting portion extends into the threading hole, and the limiting portion abuts against the wire fixing member to limit the displacement of the wire fixing ring.

During maintenance, the mounting portion can be twisted and removed from the threading hole, without affecting the disassembly and assembly maintenance and line replacement operations, and without increasing the operation time.
[0011] Furthermore, the through hole passes through the limiting part and the mounting part, and one end of the through hole close to the mounting part is provided with a rounded arc surface to prevent the robot arm line group from being scratched. The setting of the rounded arc surface prevents the sharp edge from scratching the line group, effectively avoiding the wear of the line group.
[0012] Furthermore, the wire assembly also includes a wire tube, which is installed on the joint body, and the wire group passing through the wire fixing ring is led out of the joint body through the wire tube. The wire tube wraps the scattered wire group and passes through the inside of the joint body, which plays a role in protecting the wire group, greatly reducing the wear of the wire group, and also isolating the risk of temperature transfer and leakage to a certain extent.
[0013] Furthermore, both ends of the inner hole of the wire tube are provided with rounded arc surfaces to prevent the robot arm wire group from being scratched. The setting of the rounded arc surface prevents the sharp edges of the wire tube at both ends from scratching the wire group when the robot arm is running, effectively avoiding the wear of the wire group.
[0014] Furthermore, the inner diameter of the wire fixing ring is smaller than the inner diameter of the inner hole of the wire tube. The inner diameter of the wire fixing ring is smaller than the inner diameter of the inner hole of the wire tube, and is also necessarily smaller than the inner hole of the reducer. When wiring the robot joints, there is no need to worry about the wire group diameter exceeding the inner hole diameter of the reducer, which greatly reduces the workload of circuit wiring and improves line reliability and safety.
[0015] Furthermore, the central axis of the through hole of the wire fixing ring is arranged to coincide with or be parallel to the central axis of the inner hole of the wire passing tube.

[0027] The wire fixing member 3 includes a first plate portion 6, a second plate portion 7, and a bending portion 8 connecting the first plate portion 6 and the second plate portion 7. The bending portion 8 is bent from the first plate portion 6, and the second plate portion 7 is bent from the bending portion 8. The first plate portion 6 and the second plate portion 7 are parallel, the first plate portion 6 is connected to the joint body 1, and the threading hole 4 is provided on the second plate portion 7.

[0029] There are two threading holes 4. Multiple groups of threading holes 4 can be used to distinguish and bundle different types of wire groups, such as strong current, weak current, control signal, air pipe, etc., to facilitate identification, management and maintenance.

The robot arm wire group enters the joint body 1 from the external robot arm. The wire group is passed through the wire fixing ring 5 to avoid wear of the wire group. The positioning function of the wire fixing piece 3 and the cooperation with the wire fixing ring 5 limit the overall position of the wire group. The wire fixing ring 5 limits the swinging range of the wire group. The wire group passed through the wire fixing ring 5 is aligned with the wire tube 11 and passed through. The wire fixing ring 5 restricts the thickness of the wire passed therein to be able to pass through the wire tube 11.
