Description

Technical Field

[0001] This application relates to the technical field of cable processing, and in particular to a cable tensile test device for cable processing. Background Art

[0002] Cables are important devices for transmitting electricity, communication, and signals, and their quality is directly related to the safe and stable operation of the power system. Cable tensile force is one of the important indicators for measuring cable quality.

[0003] After checking the publication number: CN218865666U, a cable tensile test device for cable processing is disclosed. In this technology, "a machine cover is installed on the top of the base, a chute is arranged on the top of the base, and a second adjusting screw rod is installed inside the chute" and other technical solutions are disclosed, which have the technical effects that the tensile force is maintained on one axis as a whole, the test accuracy is more precise, and at the same time, the temperature inside the whole device can be adjusted, and different harsh environment temperatures can be simulated, so as to realize the test of the anti-tensile performance of the cable under harsh conditions, making the test results more in line with the facts and more persuasive.

[0004] Regarding the above related technologies, the inventor believes that the device still has the following problems:

[0005] First of all, the device uses two fixing parts to conduct a linear tensile test on the cable. However, in the actual use environment, the tensile force on the cable is variable, and torsion, etc. may cause the outer sheath to break more easily. Therefore, the accuracy of the test results obtained by this device is poor.

[0006] Secondly, the device uses a bidirectional threaded rod and two fixing parts to conduct a bidirectional tensile test on the cable. However, in actual applications, the situation of both ends being stressed simultaneously is less, and instead, the situation of the middle being stressed is more common. Therefore, the technical solution of pulling both sides simultaneously used in this device is inappropriate.

[0007] In view of the above problems, the inventor proposes a cable tensile test device for cable processing to solve the above problems. Utility Model Content

[0008] In order to improve the problem that the above device cannot test torsion, the purpose of the present utility model is to provide a cable tensile test device for cable processing.

[0009] To solve the above problems, the present utility model provides the following solution: A cable tensile test device for cable processing, including a bottom plate. On both sides of the top end of the bottom plate, vertical plates are installed. Between the two vertical plates, a first lead screw is rotatably installed. A moving plate is threadedly sleeved on the outer surface of the first lead screw. A rotating mechanism is fixedly installed on one side of the moving plate. On one side of one of the vertical plates, a support plate is fixedly installed. In the middle of the support plate, a third motor is fixedly installed. The output end of the third motor is fixedly connected to the first lead screw. On the top end of the support plate, a fixing mechanism is fixedly installed. The rotating mechanism includes a first gear. On one side of the first gear, a first motor is provided, and the output end of the first motor is fixedly connected to the first gear. The outer surface of the first gear is meshed with a second gear. The middle of the second gear is fixedly connected to a rotating shaft. The other end of the rotating shaft is fixedly connected to a rotating plate. On the upper part of the side of the rotating plate facing away from the second gear, a fixing plate is fixedly connected. In the middle of the fixing plate, a second lead screw is threadedly inserted. The bottom end of the second lead screw is fixedly connected to an upper clamping cylinder. Limited position rods are slidably inserted at both ends of the upper clamping cylinder. A lower clamping cylinder for cooperating with the upper clamping cylinder is fixedly connected to the lower part of the rotating plate. On the upper part of one side of the moving plate, a first support is fixedly connected. The top end of the first support is fixedly connected to the bottom end of the first motor. The limited position rods are fixedly installed on the outer surface of the rotating plate. The middle of the rotating shaft movably penetrates the moving plate.

[0010] Preferably, the fixing mechanism includes a second support. The top end of the second support is fixedly connected to a second motor. The output end of the second motor penetrates a housing and is fixedly connected to a bidirectional lead screw. On the outer surface of the bidirectional lead screw where threads in different directions are engraved, sliding blocks are threadedly sleeved. On one side of the two sliding blocks, clamping jaws are fixedly connected.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

A fixing mechanism 4 is fixedly installed on the top end of the support plate 6. The rotating mechanism 3 includes a first gear 301. A first motor 302 is arranged on one side of the first gear 301, and the output end of the first motor 302 is fixedly connected to the first gear 301. The upper part of the moving plate 2 is fixedly connected with a first support 306. The top end of the first support 306 is fixedly connected to the bottom end of the first motor 302. The first support 306 can fix the first motor 302 to prevent it from falling off. The outer surface of the first gear 301 is meshed with a second gear 304. The middle of the second gear 304 is fixedly connected with a rotating shaft 305. The middle of the rotating shaft 305 movably penetrates through the moving plate 2. The other end of the rotating shaft 305 is fixedly connected with a rotating plate 303. The first motor 302 can drive the rotating plate 303 to rotate through the first gear 301 and the second gear 304. On the upper part of the side of the rotating plate 303 facing away from the second gear 304, a fixing plate 311 is fixedly connected. A second lead screw 307 is threadedly inserted in the middle of the fixing plate 311. The bottom end of the second lead screw 307 is fixedly connected with an upper clamping cylinder 308. The two ends of the upper clamping cylinder 308 are slidably inserted with limiting rods 309. The limiting rods 309 are fixedly installed on the outer surface of the rotating plate 303. A lower clamping cylinder 310 which is used in cooperation with the upper clamping cylinder 308 is fixedly connected to the lower part of the rotating plate 303. By screwing the second lead screw 307, the second lead screw 307 can fix one end of the cable through the upper clamping cylinder 308. Start the third motor 8 below. The third motor 8 drives the moving plate 2 through the first lead screw 7. The moving plate 2 will drive one end of the cable fixed by the rotating mechanism 3 to pull it for tensile test.

[0024] Working principle: First, place one end of the cable to be tested between the two clamping jaws 407, and then start the second motor 401. The second motor 401 drives the bidirectional threaded rod 403 to rotate. The bidirectional threaded rod 403 drives the two sliders 404 sleeved on its outer surface to move. The two sliders 404 drive the two clamping jaws 407 to move towards the middle along the chute 406. The two clamping jaws 407 moving towards the middle will fix the cable, and subsequent tests can be carried out.

[0025] Then place the other end of the cable to be tested between the upper clamping cylinder 308 and the lower clamping cylinder 310. Turn the second lead screw 307. The second lead screw 307 drives the upper clamping cylinder 308 to move downward along the limiting rod 309. The upper clamping cylinder 308 and the lower clamping cylinder 310 cooperate to clamp the cable. After clamping, start the third motor 8. The third motor 8 drives the first lead screw 7 to rotate. The first lead screw 7 drives the moving plate 2 to move. The moving plate 2 drives the rotating mechanism 3 to pull the cable, so as to conduct a tensile test on the cable. Finally, start the first motor 302. The first motor 302 drives the first gear 301 to rotate. The first gear 301 drives the second gear 304 to rotate. The second gear 304 drives the rotating shaft 305 to rotate. The rotating shaft 305 drives the rotating plate 303 to rotate. The rotating plate 303 drives the fixing plate 311 and the lower clamping cylinder 310 to rotate. The fixing plate 311 drives the upper clamping cylinder 308 to rotate. The upper clamping cylinder 308 and the lower clamping cylinder 310 jointly drive the cable to rotate, so as to conduct extreme tests such as twisting on the cable.
