[0078] The application also provides a use method of the cable aging performance testing device, which comprises the following specific use steps:

[0079] Step 1: first, set one end of the cable to be tested in the containing groove of one of the mounting columns, then rotate the screw, clamp and fix one end of the cable by the clamping blocks on both sides of the containing groove, and connect one end of the cable with one of the wire seats, rotate the rotating block and the protrusion in the mounting groove clockwise along with the clockwise rotation of the servo motor, the protrusion is pressed against the inner wall of the mounting groove, and the mounting block, the rotating disc and the movable disc are rotated clockwise together, so that the cable to be tested is arranged around the plurality of mounting columns, and the other end of the cable is fixed on another mounting column and connected with another wire seat;

[0080] Step 2: Next, by rotating the fixing rod along the inner cavity of the upper limit groove of the sleeve, and then moving the fixing rod and the limiting rod vertically upward, the top of the limiting rod slides into one of the limiting holes to limit and fix the rotating disk. Then, the servo motor rotates counterclockwise, driving the rotating block to rotate together. The first connecting column slides in the extrusion groove and presses against the inner wall of the extrusion groove, causing the movable ring to move vertically downward along the rotating block, driving the connecting rod to move together, so that the connecting rod separates from the connecting hole, releasing the connection between the rotating disk and the movable disk. The movable ring drives the second movable rod to move vertically downward, and the second connecting column slides in the connecting groove and presses against the inner wall of the connecting groove, pushing the extrusion block to press and fix the mounting block.

[0081] Step 3: Next, by rotating the rotating block and the protrusion counterclockwise, the protrusion rotates in the mounting groove, and the first connecting post pushes the movable ring to rotate counterclockwise. The first connecting block and the second connecting block rotate together with the movable ring, driving the connecting rod to rotate counterclockwise. The connecting rod pushes the locking block and the movable plate to rotate counterclockwise. The second movable groove on the movable plate squeezes and pushes the fixed post. The fixed post moves along the inner cavity of the first movable groove, driving multiple mounting posts to expand outward, causing the cable to stretch and deform. The cable is then subjected to an aging test in the test chamber.

[0082] The technical effects and advantages of this invention are as follows:

[0083] (1) The present invention utilizes a combination of rotating blocks, protrusions, mounting grooves, rotating disks, mounting posts and clamping blocks. By placing one end of the cable to be tested in the receiving groove of one of the mounting posts, and then rotating the screw, the clamping blocks on both sides of the receiving groove clamp and fix one end of the cable. As the servo motor rotates clockwise, it drives the rotating block and protrusion to rotate in the mounting groove. The protrusion presses against the inner wall of the mounting groove, pushing the mounting block, rotating disk and movable disk to rotate clockwise together, so that the cable to be tested is arranged around multiple mounting posts, and the cable is stably connected, which facilitates the testing of the cable.

[0084] (2) The present invention utilizes a combination of rotating block, protrusion, mounting groove, first connecting post, movable ring, connecting rod, second movable groove, fixed post and mounting post. By rotating the rotating block and protrusion counterclockwise, the protrusion rotates in the mounting groove. The first connecting post pushes the movable ring to rotate counterclockwise. The first connecting block and the second connecting block rotate together with the movable ring, driving the connecting rod to rotate counterclockwise. The connecting rod pushes the locking block and the movable disk to rotate counterclockwise. The second movable groove on the movable disk squeezes and pushes the fixed post. The fixed post moves along the inner cavity of the first movable groove, driving multiple mounting posts to expand outward, stretching and deforming the cable, improving the comprehensiveness of the test, and facilitating the aging test of the cable.

[0085] (3) The present invention utilizes a combination of a limiting rod, a fixing rod, a limiting groove, a limiting hole, a first connecting post, a pressing groove, a connecting rod, a connecting hole, and a movable ring. By rotating the fixing rod along the inner cavity of the upper limiting groove of the sleeve, and then moving the fixing rod and the limiting rod vertically upward, the top of the limiting rod slides into one of the limiting holes to limit and fix the rotating disk. Then, the servo motor rotates counterclockwise, driving the rotating block to rotate together. The first connecting post slides in the pressing groove and presses against the inner wall of the pressing groove, causing the movable ring to move vertically downward along the rotating block, driving the connecting rod to move together, so that the connecting rod separates from the connecting hole, releasing the connection between the rotating disk and the movable disk, and rotating the movable disk counterclockwise to facilitate the stretching and deformation of the cable.

[0110] How to use this invention:

[0111] First, by placing one end of the cable to be tested in the receiving groove 56 of one of the mounting posts 54, and then rotating the screw 58, the clamping blocks 57 on both sides of the receiving groove 56 clamp and fix one end of the cable, and connect one end of the cable to one of the terminal blocks 59. As the servo motor 611 rotates clockwise, it drives the rotating block 69 and the protrusion 610 to rotate in the mounting groove 68. The protrusion 610 presses against the inner wall of the mounting groove 68, pushing the mounting block 67, the rotating disk 53 and the movable disk 71 to rotate clockwise together, so that the cable to be tested is arranged around multiple mounting posts 54, and the other end of the cable is fixed on another mounting post 54 and connected to another terminal block 59.

[0112] Next, by rotating the fixing rod 812 along the inner cavity of the upper limit groove 813 of the sleeve 89, and then moving the fixing rod 812 and the limiting rod 810 vertically upward, the top of the limiting rod 810 slides into one of the limiting holes 814 to limit and fix the rotating disk 53. Then, the servo motor 611 rotates counterclockwise, driving the rotating block 69 to rotate together. The first connecting post 713 slides in the extrusion groove 714 and presses against the inner wall of the extrusion groove 714, causing the movable ring 712 to move vertically downward along the rotating block 69, driving the connecting rod 77 to move together, causing the connecting rod 77 to separate from the connecting hole 715, releasing the connection between the rotating disk 53 and the movable disk 71. The movable ring 712 also drives the second movable rod 88 to move vertically downward, and the second connecting post 87 slides in the connecting groove 86 and presses against the inner wall of the connecting groove 86, pushing the extrusion block 83 to press and fix the mounting block 67.

[0113] Next, by rotating block 69 and protrusion 610 counterclockwise, protrusion 610 rotates within mounting groove 68, and the first connecting post 713 pushes movable ring 712 to rotate counterclockwise. The first connecting block 79 and the second connecting block 711 rotate together with movable ring 712, driving connecting rod 77 to rotate counterclockwise. Connecting rod 77 pushes locking block 78 and movable disk 71 to rotate counterclockwise. The second movable groove 74 on movable disk 71 squeezes and pushes fixed post 75. Fixed post 75 moves along the inner cavity of first movable groove 73, driving multiple mounting posts 54 to expand outward, causing tensile deformation of the cable, and aging test of the cable is carried out in test chamber 2.
