Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] A cable rotating bracket for a robot joint arm, which is installed at the joint of the robot and is used to transmit cables of the robot joint arm and install and fix the cables to prevent the cables from being entangled and damaged during the operation of the robot joint arm.

[0028] like Figure 1-Figure 7 As shown, the rotating bracket includes a bracket seat 1, on which a rotating shaft 11 is fixed, and a fixed cover 12 is rotatably connected to the rotating shaft 11. Arc grooves 13 are provided inside the bracket seat 1 and the fixed cover 12, and a reinforcing plate 17 is fixed inside the fixed cover 12, and one side of the reinforcing plate 17 is set as an arc surface.

[0029] A circular hole 15 is provided at one end of the bracket seat 1 away from the rotating shaft 11, and a connecting block 14 is fixedly provided at one end of the fixing cover 12 away from the rotating shaft 11. The connecting block 14 is plugged into the circular hole 15, and a threaded hole is provided on the connecting block 14. Bolts are screwed into the connecting block 14 from the bottom of the bracket seat 1 to connect and fix the bracket seat 1 and the fixing cover 12, thereby improving the structural stability of the rotating bracket.

[0030] A plurality of locking blocks 16 are provided at the bottom of the support base 1 for fixing the support base 1 to the joint arm of the robot.

[0031] A wire harness is rotatably installed in the bracket seat 1, and the wire harness includes two hemispherical blocks 2. A curved block 25 is fixedly installed on one side of the hemispherical block 2. The curved block 25 is rotatably installed between the bracket seat 1 and the fixed cover 12. The two curved blocks 25 form a wire harness tube. A rubber ring 3 is fixedly installed in the wire harness tube. A fan-shaped block 26 is fixedly installed at one end of the curved block 25.

[0032] The hemispherical block 2 is provided with symmetrically distributed through holes 24, and the screw passes through the through holes 24 and is fixedly connected to the nut, which is used to connect the two hemispherical blocks 2 so that the two hemispherical blocks 2 are connected to each other to form a spherical block. The spherical block is movably installed in the arc groove 13, and the arc surface of the reinforcing plate 17 abuts against the outer side of the spherical block. The spherical block rotates on the bracket seat 1. When the cable rotates at the robot joint arm, the cable is fixed to prevent the cable from loosening, thereby increasing the service life of the robot arm.

An array of spacing grooves 32 are provided in the rubber ring 3. When the rubber ring 3 is squeezed, the spacing grooves 32 improve the compression resistance of the rubber ring 3. In addition, bevel grooves 33 are provided at both ends of the rubber ring 3. When the cable passes into the rubber ring 3, the smoothness of the cable installation can be guaranteed, thereby improving the convenience of installation.

[0035] Here’s how it works:

[0036] Install the robot joint arm cable in the rubber ring 3, and then assemble the two hemispherical blocks 2, use the trapezoidal block 27 and the trapezoidal groove 28 to position and install, complete the assembly of the hemispherical block 2, use the arc block 25 to fix the rubber ring 3, and then use the bolts to lock the hemispherical block 2. At this time, the spherical block is fixed on the cable.

[0037] Then, the spherical block is rotated and installed in the arc groove 13, the fixed cover 12 is rotated and buckled on the bracket seat 1, the connecting block 14 is inserted into the circular hole 15, the fixed cover 12 is locked, and then the fixed cover 12 is locked with bolts, so that the fixed cover 12 is locked on the bracket seat 1, thereby fixing the spherical block.
