Description

Technical Field

[0001] This utility model relates to the field of cable tensile testing technology, and in particular to a cable tensile testing device for cable processing. Background Technology

[0002] A cable tensile testing device for cable processing, with announcement number CN221174207U, includes a base mechanism. A first fixing mechanism and a second fixing mechanism are connected to the top of the base mechanism, and a protective cover is connected to the outside of the base mechanism. This cable tensile testing device uses anti-slip pads to make the clamping of the cable by the first and second fixing clamps more stable. The protective cover prevents the cable from breaking and flying out, injuring the operator. A first cylinder, linked to a tensile detector, pulls the second fixing mechanism, causing it to slide along a groove until the cable breaks. The tensile test result can then be obtained through the tensile detector. This device solves the problem of overly complex operation methods used to prevent cable detachment during testing, where the protective base and transparent plate cannot prevent the cable from flying out and injuring the operator if the cable does not break in the middle.

[0003] The cable tensile testing device for cable processing mentioned above may cause cracks or damage to the cable insulation layer when stress exists inside the cable during tensile testing. This may reduce the insulation performance of the cable and even cause safety problems such as short circuits, affecting the tensile test results and reducing the working efficiency of the cable tensile testing device.

Two sets of clamping blocks 12 are arranged on each of the two sets of connecting housings 6. The tensioning mechanism 3 is arranged on the mounting housing 2. The tensioning mechanism 3 is used to relieve stress on the cable under test tensile force.

[0022] The tensioning mechanism 3 includes a motor 301, rotating short bars 302, and gears 303. The motor 301 is fixedly installed on the rear side of the mounting housing 2. Four sets of rotating short bars 302 are rotatably installed on the inner wall of the rear side of the mounting housing 2. A set of gears 303 is fixedly installed on the outer wall of the two sets of rotating short bars 302 located at the bottom. The two sets of gears 303 mesh with each other. The tensioning mechanism 3 can slightly stretch the cable that needs to be tensile tested to remove internal stress, preventing the internal stress of the cable from causing cracks or damage to the cable insulation layer during tensile testing. This avoids reducing the insulation performance of the cable or even causing safety problems such as short circuits, and improves the accuracy of the tensile test results.

[0023] One end of each of the four sets of rotating short bars 302 is fixedly installed with a set of rotating circular plates 4.

[0024] A mounting housing 2 is fixedly installed on the top of the tensile testing machine body 1. A cylinder 5 is fixedly installed on the top of the mounting housing 2. The free end of the cylinder 5 extends into the interior of the mounting housing 2 and is fixedly installed with a set of connecting housings 6. The top of the tensile testing machine body 1 is fixedly connected to another set of connecting housings 6. A set of bidirectional threaded rods 8 is rotatably installed inside each of the two sets of connecting housings 6. Two sets of moving blocks 9 are threadedly connected to the outer walls of each of the two sets of bidirectional threaded rods 8. One end of each of the two sets of bidirectional threaded rods 8 extends to one side of the connecting housing 6 and is fixedly installed with a handle 10. There are four sets of moving blocks 9.

[0027] Working principle: Before conducting a tensile test on a cable, the cable to be tested is placed between two sets of rotating discs 4 located below through a rectangular opening on the other side of the tensile testing machine body 1. The starting motor 301 is controlled, and the rotation of the motor 301 drives a set of rotating short bars 302 to rotate. Through two sets of meshing gears 303, the two sets of rotating discs 4 below rotate, compressing and stretching the cable. When the entire cable passes between the two sets of rotating discs 4 above, the cable is removed. The cylinder 5 is activated, and the cylinder 5 drives a set of connecting housings 6 to move downward. The two sets of connecting housings 6 are adjusted to a suitable distance, and the two ends of the cable are placed between two sets of clamping blocks 12.
