Description

Technical Field

[0001] This utility model relates to the technical field of tensile testing machines, specifically a tensile testing machine for processing automotive lighting wiring harnesses. Background Technology

[0002] A tensile testing machine, also known as a universal testing machine, is a mechanically applied testing machine used to perform static load, tensile, and compressive mechanical property tests on various materials. It is suitable for testing the physical and mechanical properties of materials such as wires and cables, steel, and fiberglass.

[0003] According to a public announcement of a new type of tensile testing machine (Announcement No.: CN210090195U), the aforementioned application uses a drive motor and push-pull rod to compress and stretch the workpiece, thereby measuring the force through a tensile sensor and performing precise data analysis through an intelligent control and recording device, thus improving the accuracy of the test results.

[0004] However, in actual use, the above-mentioned equipment will subject the wire harness to tension when the equipment clamps the wire harness and then conducts a tensile test, which will cause the wire harness between the clamping components to move, thus causing deviation in the experimental data; in view of this, we propose a tensile testing machine for automotive lighting wire harness processing. Summary of the Invention

[0005] The purpose of this invention is to provide a tensile testing machine for processing automotive lighting wiring harnesses, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tensile testing machine for processing automotive lighting wiring harnesses, comprising a testing machine body, a fixing component fixedly connected to the upper surface of the testing machine body, a moving component fixedly connected to the upper surface of the testing machine body, and a limiting component provided on the front of the moving component, the limiting component comprising: A movable block is disposed on the front of the movable component, a connecting block is fixedly connected to the bottom of the movable block, and an installation component is fixedly connected to the bottom of the connecting block; A bidirectional threaded rod is rotatably connected to the side of the mounting component. A guide rod is fixedly connected to the inner wall side of the mounting component. A slot is provided on the inner wall side of the mounting component. A fixing component is fixedly connected to the front of the mounting component. A movable slot is provided on the front of the fixing component. A limiting block is threadedly connected to the outer surface of a bidirectional threaded rod. A placement groove is provided on the side of the limiting block. A threaded post is fixedly connected to the front of the limiting block. An electric telescopic rod is fixedly connected to the side of the limiting block away from the placement groove. A nut is threadedly connected to the outer surface of the threaded post. A pressing block is fixedly connected to the end of the electric telescopic rod.

[0007] Preferably, the center of the pressing block corresponds to the center of the end of the electric telescopic rod, and the pressing block is disposed inside the placement groove, which allows the pressing block to move inside the placement groove.

[0008] Preferably, the limiting block is slidably connected to the outer surface of the guide rod, and the pressing block is provided with an anti-slip strip on its side, which increases the friction between the pressing block and the wire harness.

[0009] Preferably, the position of the threaded post corresponds to the position of the movable groove, and the center of the threaded post corresponds to the center of the movable groove, which allows the threaded post to move inside the movable groove.

[0010] Preferably, the bottom of the fixing member is provided with an auxiliary component, the auxiliary component including a connecting plate, the connecting plate being fixedly connected to the bottom of the fixing member, and a limiting member being fixedly connected to the side of the connecting plate.

[0011] Preferably, the center of the connecting plate corresponds to the center of the fixing member, and the bottom of the connecting plate is located below the bottom of the limiting block.

[0012] Preferably, the center of the limiting member corresponds to the center of the connecting plate, and the side of the limiting member is provided with a U-shaped groove.

[0013] Compared with the prior art, this utility model provides a tensile testing machine for processing automotive lighting wiring harnesses, which has the following beneficial effects: 1. This tensile testing machine for automotive lighting wiring harness processing, in order to make the wiring harness more securely positioned, places the outer surface of the wiring harness between the limiting blocks, rotates the bidirectional threaded rod to move the limiting blocks closer to the outer surface of the wiring harness, and at the same time allows the threaded post to move inside the movable groove. After the limiting blocks limit the wiring harness, the electric telescopic rod extends to allow the pressing block to extend out of the placement groove, so that the side of the pressing block contacts the wiring harness. Then, the nut is used to limit the threaded post. This makes the wiring harness more stable when subjected to tensile force.

[0014] 2. This tensile testing machine for automotive lighting wiring harness processing, in order to keep the wiring harness in a vertical state, after the outer surface of the wiring harness is limited by a limiting block near the end, the wiring harness is straightened and then the outer surface of the wiring harness is clamped inside the limiting component. This allows the wiring harness to quickly maintain a vertical state. The other end of the wiring harness is then limited by a fixing component, which makes the tensile data of the wiring harness more accurate. Attached Figure Description

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: a tensile testing machine for processing automotive lighting wiring harnesses, including a testing machine body 1, a fixing component 2 fixedly connected to the upper surface of the testing machine body 1, a moving component 3 fixedly connected to the upper surface of the testing machine body 1, a limiting component 4 provided on the front of the moving component 3, the limiting component 4 including a moving block 401, a connecting block 402, a mounting component 403, a bidirectional threaded rod 404, a guide rod 406, a slot 405, a fixing component 413, a movable groove 414, a limiting block 407, a placement groove 408, a threaded column 411, an electric telescopic rod 409, a nut 412, and a pressing block 410.

[0018] In this embodiment of the present invention, a movable block 401 is disposed on the front of the movable component 3. A connecting block 402 is fixedly connected to the bottom of the movable block 401, and a mounting component 403 is fixedly connected to the bottom of the connecting block 402. A bidirectional threaded rod 404 is rotatably connected to the side of the mounting component 403. A guide rod 406 is fixedly connected to the inner wall side of the mounting component 403. A slot 405 is provided on the inner wall side of the mounting component 403. A fixing component 413 is fixedly connected to the front of the mounting component 403. A movable groove 414 is provided on the front of the fixing component 413. A limiting block 407 is threadedly connected to the outer surface of the bidirectional threaded rod 404. The limiting block 407 is slidably connected to the outer surface of the guide rod 406. A placement groove 408 is provided on the side of the limiting block 407. A threaded post 411 is fixedly connected to the front of the limiting block 407. The position of the threaded post 411 corresponds to the position of the movable groove 414, and the center of the threaded post 411 corresponds to the center of the movable groove 414, which allows the threaded post 411 to move inside the movable groove 414. The side of the limiting block 407 away from the placement groove 408 is fixedly connected to an electric telescopic rod 409. The outer surface of the threaded post 411 is threadedly connected to a nut 412. The end of the electric telescopic rod 409 is fixedly connected to a pressing block 410, and the center of the pressing block 410 corresponds to the center of the end of the electric telescopic rod 409. The pressing block 410 is set inside the placement groove 408, which allows the pressing block 410 to move inside the placement groove 408. The side of the pressing block 410 is provided with an anti-slip strip, which increases the friction between the pressing block 410 and the wire harness.

[0019] Meanwhile, an auxiliary component 5 is provided at the bottom of the fixing component 413. The auxiliary component 5 includes a connecting plate 501, which is fixedly connected to the bottom of the fixing component 413. The center of the connecting plate 501 corresponds to the center of the fixing component 413. The bottom of the connecting plate 501 is located below the bottom of the limiting block 407. A limiting component 502 is fixedly connected to the side of the connecting plate 501. The center of the limiting component 502 corresponds to the center of the connecting plate 501. A U-shaped groove is provided on the side of the limiting component 502. This allows the wire harness to be straightened after being limited by the limiting block 407 near the end of the outer surface of the wire harness. The outer surface of the wire harness can then be snapped into the inside of the limiting component 502. This allows the wire harness to be quickly kept vertical. The other end of the wire harness is then limited by the fixing component 2, which makes the tension data of the wire harness more accurate.

[0020] In this invention, during use, the outer surface of the wire harness is placed between the limiting blocks 407. The bidirectional threaded rod 404 is rotated to bring the limiting blocks 407 closer to the outer surface of the wire harness, while the threaded post 411 moves inside the movable groove 414. After the limiting blocks 407 limit the wire harness, the electric telescopic rod 409 extends to allow the pressing block 410 to extend out of the placement groove 408, so that the side of the pressing block 410 contacts the wire harness. Then, the nut 412 is used to limit the threaded post 411. This makes the wire harness more stable when subjected to tension.

[0021] Furthermore, after the wire harness is stopped by the limiting block 407 near the end of the outer surface, the wire harness is straightened and then the outer surface of the wire harness is snapped into the limiting member 502. This allows the wire harness to be quickly kept vertical. The other end of the wire harness is then stopped by the fixing component 2, which makes the tension data of the wire harness more accurate.

[0022] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
