AI Technical Summary
Traditional robot cables lack flexible, buffered installation during installation, making them prone to damage under prolonged braking.
The cable support consists of a locking sleeve frame, a magnetic base plate, a mounting bracket, a support spring assembly, a support pivot, and a limit pivot. Through the elastic buffer structure of the guide-type support spring rod and the sleeve, the vertical and vertical directions of the cable are buffered, avoiding excessive traction.
It effectively alleviates damage to cables caused by torsion and bending movements in multi-joint robotic arms or multi-degree-of-freedom machines, and improves the cable's durability and service life.

Description
Technical Field
[0001] This utility model relates to a tensile-resistant robot arm control cable, belonging to the field of cable installation technology. Background Technology
[0002] Robot cables, as the name suggests, are flexible cables used inside robotic arms. These cables must withstand the torsion, bending, and high-intensity movements of multi-jointed manipulators or multi-degree-of-freedom machines in three-dimensional space. Because robots need to operate in various complex environments, high demands are placed on the robot's cables to withstand continuous torsional and bending mechanical stresses and to adapt to environmental conditions. Traditional cables lack flexible, position-adjustable buffering during installation, and prolonged braking and traction can easily damage the cables. Utility Model Content

The base is connected to the robotic arm via the first swing arm, the second swing arm, and the third swing arm. A mechanical gripper is installed on the brake shaft of the robotic arm. The cable control line is externally laid and electrically connected via the cable bracket.
[0005] Preferably, the cable bracket consists of a locking sleeve frame, a magnetic base plate, a mounting bracket, a support spring assembly, a support shaft, and a limiting shaft. The locking sleeve frame is located at the upper and lower ends of the magnetic base plate. The mounting bracket is vertically welded to the center of the magnetic base plate. The support shaft is mounted on the support spring assembly through the central axis groove of the mounting bracket. The limiting shaft is welded to the outer side of the arc apex of the mounting bracket.
[0006] Preferably, the locking sleeve frame consists of a guide-type support spring rod, a sleeve, and a locking screw. The guide-type support spring rod is positioned and installed in the bottom through hole of the sleeve, and the locking screw is threadedly installed at the center position of the arc apex axis of the sleeve.
[0007] Preferably, the spring assembly of the guide-type support spring rod is installed at the upper and lower ends of the sleeve.
[0008] Compared with the prior art, the beneficial effects of this utility model are:
[0009] The cable support consists of a locking sleeve frame, a magnetic base plate, a mounting bracket, a support spring assembly, a support shaft, and a limit shaft. The locking sleeve frame consists of a guide-type support spring rod, a sleeve, and a locking screw. When the cable swings with a small distance, the cable inside the sleeve moves up and down vertically through the elastic buffer of the guide-type support spring rod, providing vertical buffering. The support spring assembly, in conjunction with the support shaft, provides horizontal elastic support for the cable, providing vertical buffering to avoid excessive traction.

Detailed Implementation
[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0016] like Figures 1-4 As shown, a tensile-resistant robot arm control cable includes a base 1, a first swing arm 2, a second swing arm 3, a third swing arm 4, a robotic arm 5, a mechanical gripper 6, a cable control line 7, and a cable bracket 8. The base 1 is connected to the robotic arm 5 via the first swing arm 2, the second swing arm 3, and the third swing arm 4. The robotic arm 5 has a mechanical gripper 6 mounted on its brake shaft. The cable control line 7 is externally laid and electrically connected via the cable bracket 8.
[0017] The cable support 8 consists of a locking sleeve 9, a magnetic base plate 10, a mounting bracket 11, a support spring assembly 12, a support shaft 13, and a limiting shaft 14. The locking sleeve 9 is located at the upper and lower ends of the magnetic base plate 10. The mounting bracket 11 is vertically welded to the center of the magnetic base plate 10. The support shaft 13 is mounted on the central axis through the groove of the mounting bracket 11 via the support spring assembly 12. The limiting shaft 14 is welded to the outer side of the arc top of the mounting bracket 11. The support spring assembly 13, in conjunction with the support shaft 14, provides lateral elastic support for the cable and provides vertical buffering to avoid excessive traction.
[0018] The locking sleeve frame 9 consists of a guide-type support spring rod 15, a sleeve 16, and a locking screw 17. The guide-type support spring rod 15 is positioned and installed in the bottom through hole of the sleeve 16. The locking screw 17 is threaded and installed at the center of the arc apex axis of the sleeve 16. When the cable swings with a small distance, the cable inside the sleeve 16 moves up and down through the elastic buffer of the guide-type support spring rod 15 to provide vertical buffering.
[0019] The spring assembly of the guide-type support spring rod 15 is installed at the upper and lower ends of the sleeve 16 for stable elastic buffering.
[0020] Specific usage: A tensile-resistant robot arm control cable, the cable control line is laid on the outside of the swing arm, the magnetic base plate of the cable bracket has strong magnetic attraction and good stability performance. The cable passes through the upper locking sleeve frame, the support shaft and the lower locking sleeve frame in sequence to form an arc structure. The limiting shaft limits the cable. When the cable swings with a small distance, the cable in the inner diameter of the sleeve moves up and down to provide vertical buffering through the elastic buffering of the guide-type support spring rod. The support spring group cooperates with the support shaft to provide horizontal elastic support for the cable to provide vertical buffering, avoiding excessive traction.
