[0005] 2. There is a method of installing the cables inside the robot arm, which does not affect the appearance. However, during the long-term movement of the robot arm, the internal wires are not fixed and may become tangled, which is not conducive to subsequent maintenance and identification and replacement of circuit cables. Utility Model Content

[0006] In view of the problems raised by the above background technology, the purpose of the present utility model is to provide a six-axis welding manipulator with a wire harness protection mechanism.

[0007] In order to achieve the above technical objectives, the technical solutions adopted by this utility model are as follows:

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 4 As shown, the utility model is a six-axis welding manipulator with a wire harness protection mechanism, comprising a six-axis welding manipulator 1, a wire trough 2 is provided on the connecting rod of the six-axis welding manipulator 1, threaded columns 3 are installed at the four corners of the wire trough 2, a cover 4 is installed on the wire trough 2, the cover 4 is provided with screw holes 5 corresponding to the positions of the threaded columns 3, the screw holes 5 and the threaded columns 3 are matched with locking screws 6, wire holes 7 are provided at both ends of the wire trough 2, a plurality of threaded holes 8 are evenly provided on the bottom of the wire trough 2, and the threaded holes 8 are threadedly connected to the wire harness mechanism 9;

[0027] The wiring harness mechanism 9 includes a male block 91 and a female block 92. The male block 91 and the female block 92 are connected to form a cylinder. The outer sides of the male block 91 and the female block 92 are provided with external threads 93 that match the threaded holes 8. The tops of the male block 91 and the female block 92 are provided with ear plates 94. The insides of the male block 91 and the female block 92 are provided with large column grooves 95 and small column grooves 96. The large column grooves 95 and the small column grooves 96 are connected. Two semi-cylinders 97 are placed in the small column groove 96. The ends of the two semi-cylinders 97 are connected to the clamping table 98 located in the large column groove 95, and the other ends of the two semi-cylinders 97 are connected to the wiring harness ring 99.

[0028] In this embodiment, when using a six-axis welding robot with a cable protection mechanism, the cable is passed through the cable holes 7 at both ends of the cable trough 2. The cable route is limited by the cable binding mechanism 9 installed in the cable trough 2 to prevent the cable from being displaced in the non-axial direction, thereby achieving the purpose of cable protection.

[0029] The densely distributed threaded holes 8 in the cable trough 2 can be used to install any number of cable harnessing mechanisms 9 at any position according to the needs, so as to restrain any number of cables;

[0030] The way to use the cable tie mechanism 9 is to clamp the cable tie ring 99 on the outside of the cable through the two open semi-cylinders 97, and then use the male block 91 and the female block 92 to clamp the two semi-cylinders 97 in the internal small column groove 96 and the large column groove 95. The space in the large column groove 95 supports the cable tie ring 99 to move up and down a small distance, increasing the flexibility of use, and then the combined male block 91 and the female block 92 can be screwed into the threaded hole 8 at the corresponding position with the external thread 93.

[0031] Preferably, the screw hole 5 is a countersunk hole. Such a design allows for concealed installation of the locking screw 6, resulting in a better appearance. In fact, the structural style of the screw hole 5 may also be considered according to specific circumstances.

[0032] Preferably, the four corners of the male block 91 are equipped with plug posts 910, and the female block 92 is provided with post holes 911 corresponding to the number of positions of the plug posts 910. This design allows the male block 91 and the female block 92 to be better docked, and the docking match between the external threads 93 on the male block 91 and the female block 92 is better. In fact, the docking structure of the male block 91 and the female block 92 can also be considered according to specific circumstances.

[0033] It is preferred that the clamping platform 98 is in the shape of a cone. Such a design facilitates entry into the small column groove 96. In fact, the structural shape of the clamping platform 98 can also be considered according to specific circumstances.

[0034] It is preferred that the cable tie ring 99 is integrally formed and is polished to be smooth. With this design, the integrally formed structure is less likely to have problems with opening and breaking, and after being polished to be smooth, it is less likely for burrs to scratch the cable. In fact, the cable tie ring 99 can also be optimized according to specific circumstances.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical principles disclosed herein shall be covered by the claims of the present invention.
