Description

Technical Field

[0001] The present invention relates to the technical field of wear resistance testing, and more specifically, to a wear resistance testing device for wire and cable production and a method for using the same. Background Art

[0002] In the wire and cable manufacturing industry, the wear resistance of products is one of the key indicators for quality assessment. Wear resistance is directly related to the service life and safety of wires and cables in actual application environments, especially under complex and changeable installation and use conditions, such as building wiring, vehicle wiring, underground laying, etc., wires and cables often need to withstand mechanical friction and wear from different directions. Therefore, accurate and comprehensive evaluation of the wear resistance of wires and cables is of great significance to ensure product quality, improve user experience and reduce subsequent maintenance costs.

[0003] Most traditional wire and cable wear resistance testing devices use a single-head scraper to scrape back and forth to test a specific surface of the wire and cable. Although this test method can simulate the wear of wires and cables in a specific direction to a certain extent, its limitations are obvious. First of all, since wires and cables are often winding in actual applications, their surfaces will be subject to friction and wear from all directions. Therefore, testing only a single surface cannot fully reflect the true wear resistance of wires and cables. Secondly, the reciprocating motion mode of the single-head scraper is relatively simple, and it is difficult to simulate the complex and changeable actual wear scenarios, resulting in limited functionality and practicality of the test results.

[0004] In addition, the existing wear resistance testing device also has the problem of low testing efficiency. Since multiple surfaces of wires and cables need to be tested one by one, it is not only time-consuming but also increases the testing cost. In the context of pursuing efficient production and rapid response to market demand, this inefficient testing method obviously cannot meet the needs of wire and cable manufacturers.

[0005] Therefore, it is particularly important to develop a device that can perform wear resistance testing on wires and cables in an all-round and multi-mode manner. In view of this, we propose a wear resistance testing device for wire and cable production and a method for using it. Summary of the invention

[0020] After passing the cable to be tested through the hole and tightening it, fix both ends with the cable fixing mechanism;

[0021] S2, size adjustment operation;

[0022] First, the clutch paddle is toggled so that the movable shaft drives the clutch gear B to mesh with the rotating outer gear ring, and then the servo motor is driven to drive the convex block to rotate. The convex block and the output end of the servo motor are inserted in the groove of the sleeve, thereby driving the sleeve to rotate. The sleeve pulls the transmission belt to rotate, and the transmission belt pulls the belt engagement groove and the movable shaft to rotate on the fixed seat. The movable shaft drives the clutch gear B to rotate, and the clutch gear B meshes to drive the rotating outer gear ring to rotate. Since the rotating outer gear ring is fixedly connected to the rotating inner ring, the rotating inner ring is synchronously driven to rotate on the inner wall of the rotating outer shell, and the rotating inner ring drives the intermittent inner tooth groove to rotate. The intermittent inner tooth groove meshes to make the gear rotate on the fixed shaft. The rotation of the gear makes the meshing groove of the movable grinding block meshed at the other end, so that the movable grinding block slides on the limit fixed block through the long hole to achieve the adjustment size.

[0023] S3, wear-resistant detection mode adjustment;

[0024] Select the plane wear test state or the rotation wear test state according to the required test state;

[0025] S3.1. If a plane wear test state is required, the clutch paddle is moved so that the movable shaft drives the clutch gear A to separate from the ring gear. At this time, the reduction motor is driven, and the reduction motor drives the reciprocating screw to rotate on the two bearing seats. Since the engagement block is movably plugged into the wire groove of the reciprocating screw, the rotation of the reciprocating screw drives the engagement block to reciprocate. The engagement block drives the rotating rod and the slider at the top to slide back and forth synchronously on the slide rod through the slide hole. The slider drives the rotating assembly, the size adjustment assembly and the synchronous displacement assembly to reciprocate synchronously, thereby realizing a multi-faceted plane wear test;

[0026] S3.2. If a rotational wear test state is required, the clutch paddle is moved so that the movable shaft drives the clutch gear A to engage with the ring gear, and the reduction motor is driven. The reduction motor drives the reciprocating screw to rotate on the two bearing seats. Since the engaging block is movably plugged into the wire groove of the reciprocating screw, the rotation of the reciprocating screw drives the engaging block to reciprocate. The engaging block drives the rotating rod and the slider at the top to slide synchronously back and forth on the slide rod through the sliding hole. At the same time, the servo motor is driven to drive the protrusion to rotate. The protrusion and the output end of the servo motor are inserted in the groove of the sleeve, thereby driving the sleeve to rotate. The sleeve pulls the transmission belt to rotate, and the transmission belt pulls the belt engagement groove and the movable shaft to rotate on the fixed seat. At this time, the clutch gear A is engaged with the ring gear, and the ring gear drives the rotating shell and its overall rotation, which rotates during the reciprocating process to achieve a rotational wear test.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The present invention fixes both ends of the wire and cable by symmetrically setting a cable fixing mechanism on the detection base, setting a reciprocating screw mechanism at a position close to the back of the cable fixing mechanism on the detection base, and setting an omnidirectional grinding test mechanism on the reciprocating screw mechanism. The reciprocating screw mechanism drives the rotating assembly, size adjustment assembly and synchronous displacement assembly of the omnidirectional grinding test mechanism to reciprocate and perform friction test on the cable surface. The synchronous displacement assembly in the present invention has the effect of synchronously testing wires and cables in multiple directions, and can perform friction test on wires and cables from multiple sides at the same time, which greatly shortens the test time and improves the test efficiency. For wire and cable manufacturers, this means that test results can be obtained faster, thereby accelerating product development and production progress and reducing testing costs.

[0029] 2. In the present invention, when the clutch adjustment mechanism engages with the ring teeth driving the rotating shell, the rotating shell is driven to rotate on the slider, and the rotating shell drives the size adjustment component and the synchronous displacement component to rotate as a whole, so that rotation is generated synchronously during the reciprocating process, and the cable is scraped reciprocatingly to simulate complex and changeable actual wear scenarios, such as simulating the actual scenario of the cable dragging and rubbing on the ground and generating rolling friction during use, which fully reflects the actual wear resistance of wires and cables and improves the functionality and applicability of the test.

[0030] 3. In the present invention, when the size of the size adjustment assembly needs to be adjusted, the clutch adjustment mechanism is driven to engage and drive the rotating outer gear ring. Since the rotating outer gear ring is fixedly connected to the rotating inner ring, the rotating inner ring is synchronously driven to rotate on the inner wall of the rotating outer shell. The rotating inner ring drives the intermittent inner tooth groove to rotate. The intermittent inner tooth groove is engaged to make the gear rotate on the fixed shaft. The rotation of the gear makes the meshing groove of the movable grinding block meshed at the other end, so that the movable grinding block slides on the limit fixed block through the long hole, such as Fig.11As shown, the function of adjusting the size is realized. Since the device can adapt to cables of various sizes, there is no need to frequently replace test components or adjust test settings, thereby saving test preparation time.

[0031] 4. The present invention drives the servo motor to rotate the protrusion, and the protrusion and the output end of the servo motor are inserted in the groove of the sleeve, thereby driving the sleeve to rotate, and the sleeve pulls the transmission belt to rotate, and the transmission belt pulls the belt engagement groove and the movable shaft to rotate on the fixed seat. According to the toggling of the clutch paddle, the movable shaft drives the clutch gear A and the clutch gear B to engage with the ring teeth or engage with the rotating outer gear ring. If the clutch gear A engages with the ring teeth, the ring teeth drive the rotating outer shell and its overall rotation to realize the function of switching the rotation wear-resistant test state or the plane wear-resistant test state. If the clutch gear B engages with the rotating outer gear ring, the function of adjusting the cable adaptation size is realized. The present invention has the advantages of strong functionality and high detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The present invention fixes both ends of the wire and cable by symmetrically setting a cable fixing mechanism 2 on a detection base 1, setting a reciprocating screw mechanism 3 at a position of the detection base 1 close to the back of the cable fixing mechanism 2, and setting an all-round grinding and testing mechanism 4 on the reciprocating screw mechanism 3. The reciprocating screw mechanism 3 drives the rotating component 401, the size adjustment component 402 and the synchronous displacement component 403 of the all-round grinding and testing mechanism 4 to reciprocate and perform friction testing on the cable surface. The synchronous displacement component 403 in the present invention has the effect of synchronously testing the wire and cable in multiple directions, and can perform friction testing on the wire and cable from multiple sides at the same time, which greatly shortens the test time and improves the test efficiency. For wire and cable manufacturers, this means that test results can be obtained faster, thereby accelerating product development and production progress and reducing test costs.

[0058] In an embodiment of the present invention, the reciprocating screw mechanism 3 includes a bearing seat 301, a reduction motor 302, a reciprocating screw 303, a sliding rod 304 and a moving assembly 305.

The omnidirectional grinding measurement mechanism 4 and the clutch adjustment mechanism 5 are both arranged at the top of the slider 3051. In the present invention, the reduction motor 302 is driven, and the reduction motor 302 drives the reciprocating screw 303 to rotate on the two bearing seats 301. Since the engaging block 3054 is movably plugged into the wire groove of the reciprocating screw 303, the rotation of the reciprocating screw 303 drives the engaging block 3054 to reciprocate.

[0063] In the present invention, when it is necessary to adjust the size of the size adjustment component 402, the clutch adjustment mechanism 5 is driven to engage and drive the rotating outer gear ring 4023. Since the rotating outer gear ring 4023 is fixedly connected to the rotating inner ring 4021, the rotating inner ring 4021 is synchronously driven to rotate on the inner wall of the rotating shell 4011. The rotating inner ring 4021 drives the intermittent inner tooth groove 4022 to rotate. The intermittent inner tooth groove 4022 is engaged to make the gear 4032 rotate on the fixed shaft 4031.

The present invention has the advantages of strong functionality and high detection efficiency.

[0067] Embodiment 2: This embodiment provides a method for using a wear resistance detection device for wire and cable production, comprising the following steps:

[0068] S1, cable tightening and fixing operation;

[0069] After the cable to be tested is passed through the through hole 4013 and tightened and straightened, the two ends are fixed by the cable fixing mechanism 2;

[0070] S2, size adjustment operation;

[0071] First, the clutch paddle 5075 is toggled so that the movable shaft 5071 drives the clutch gear B5074 to mesh with the rotating outer gear ring 4023, and then the servo motor 501 is driven to drive the protrusion 502 to rotate. The protrusion 502 and the output end of the servo motor 501 are inserted into the groove 504 of the sleeve 503, thereby driving the sleeve 503 to rotate, and the sleeve 503 pulls the transmission belt 505 to rotate, and the transmission belt 505 pulls the belt fitting groove 5072 and the movable shaft 5071 to rotate on the fixed seat 506, and the movable shaft 5071 drives the clutch gear B5074 to rotate, and the clutch gear B5074 meshes. The rotating outer gear ring 4023 is driven to rotate. Since the rotating outer gear ring 4023 is fixedly connected to the rotating inner ring 4021, the rotating inner ring 4021 is synchronously driven to rotate on the inner wall of the rotating outer shell 4011. The rotating inner ring 4021 drives the intermittent inner tooth groove 4022 to rotate. The intermittent inner tooth groove 4022 is engaged to make the gear 4032 rotate on the fixed shaft 4031. The rotation of the gear 4032 makes the meshing groove 4034 of the movable grinding block 4033 at the other end mesh, so that the movable grinding block 4033 slides on the limit fixed block 4014 through the long hole 4035 to achieve the size adjustment.

[0073] Select the plane wear test state or the rotation wear test state according to the required test state;

[0074] S3.1. If a plane wear test state is required, the clutch paddle 5075 is toggled so that the movable shaft 5071 drives the clutch gear A5073 to separate from the ring gear 4012. At this time, the reduction motor 302 is driven, and the reduction motor 302 drives the reciprocating screw 303 to rotate on the two bearing seats 301. Since the engaging block 3054 is movably plugged into the wire groove of the reciprocating screw 303, the rotation of the reciprocating screw 303 drives the engaging block 3054 to reciprocate. The engaging block 3054 drives the top rotating rod 3053 and the slider 3051 to slide synchronously back and forth on the slider 304 through the sliding hole 3052. The slider 3051 drives the rotating assembly 401, the size adjustment assembly 402 and the synchronous displacement assembly 403 to reciprocate synchronously, thereby realizing a multi-faceted plane wear test;

The reduction motor 302 drives the reciprocating screw 303 to rotate on the two bearing seats 301. Since the engaging block 3054 is movably plugged into the wire groove of the reciprocating screw 303, the rotation of the reciprocating screw 303 drives the engaging block 3054 to reciprocate, and the engaging block 3054 drives the top rotating rod 3053 and the slider 3051 to pass through the sliding hole 3052 on the sliding rod 304. It performs synchronous reciprocating sliding, and at the same time drives the servo motor 501 to drive the protrusion 502 to rotate. The protrusion 502 and the output end of the servo motor 501 are inserted in the groove 504 of the sleeve 503, thereby driving the sleeve 503 to rotate, and the sleeve 503 pulls the transmission belt 505 to rotate, and the transmission belt 505 pulls the belt fitting groove 5072 and the movable shaft 5071 to rotate on the fixed seat 506.
