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 that is easy to fix. 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, contributing to material development.

[0003] According to a public notice (No. CN217542640U) regarding a tensile strength testing machine for a robotic arm power distribution cabinet wiring harness, the aforementioned application adds a fixing device to the machine. This newly added fixing device is mounted on a fixed plate when not in use, so it does not affect the normal placement and storage of the machine. When needed, i.e., when testing the wiring harness, one end of the wiring harness can be inserted into the fixing device, secured, and then wound around the winding lug. This eliminates concerns about the wiring harness falling off during use.

[0004] However, in actual use, the above-mentioned equipment limits both ends of the wire harness during the test. As the limiting components fix the ends of the wire harness, the movement of the limiting components will cause displacement at both ends of the wire harness, resulting in tilting of the wire harness. This makes the test data of the wire harness inaccurate. In view of this, we propose a tensile testing machine for automotive lamp wire harness processing that is easy to fix. Summary of the Invention

[0005] The purpose of this invention is to provide a tensile testing machine for processing automotive lighting wiring harnesses that is easy to fix, 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 that is easy to fix, comprising a worktable, a clamping assembly fixedly connected to the upper surface of the worktable, a moving device fixedly connected to the upper surface of the worktable, and a limiting assembly provided on the front of the moving device, the limiting assembly comprising: A movable block is disposed on the front of the mobile device, and a connector is fixedly connected to the bottom of the movable block, and an installation component is fixedly connected to the bottom of the connector; 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, and a placement groove is provided on the inner wall side of the mounting component; A left limiting block is threadedly connected to the outer surface of a bidirectional threaded rod. A right limiting block is threadedly connected to the outer surface of the bidirectional threaded rod. An installation groove is provided on the side of the right limiting block. A small electric telescopic rod is fixedly connected to the side of the right limiting block away from the installation groove. A pressing block is fixedly connected to the end of the small electric telescopic rod. An anti-slip component is fixedly connected to the side of the pressing block.

[0007] Preferably, the anti-slip component is composed of an arc-shaped strip fixedly connected to the outer surface of the convex strip. The anti-slip component is evenly distributed in a linear array on the side of the pressing block. The anti-slip component is set inside the mounting groove, which makes the pressing block more secure in limiting the wire harness.

[0008] Preferably, the left and right limiting blocks are sleeved on the outer surface of the guide rod. The left limiting block is also provided with an installation groove, a small electric telescopic rod, a pressing block, and an anti-slip component, which allows the left and right limiting blocks to move towards the center of the mounting component when the bidirectional threaded rod rotates.

[0009] Preferably, the position of the placement slot corresponds to the position of the small electric telescopic rod, and the size of the placement slot is adapted to the size of the small electric telescopic rod, so that the small electric telescopic rod can be inserted into the placement slot.

[0010] Preferably, an auxiliary component is provided on the upper surface of the left limiting block. The auxiliary component includes a locking member, which is fixedly connected to the upper surface of the left limiting block. A fixing member is fixedly connected to the upper surface of the left limiting block, and a groove is provided on the side of the fixing member.

[0011] Preferably, the top of the card corresponds to the bottom of the fixing member, and the size of the card is adapted to the size of the fixing member.

[0012] Preferably, the size of the groove is adapted to the size of the outer surface of the wire harness, and the center of the groove corresponds to the center of the pressing block.

[0013] Compared with the prior art, this utility model provides a tensile testing machine for processing automotive lighting wiring harnesses that is easy to fix, and has the following beneficial effects: 1. This tensile testing machine for easy-to-fix vehicle headlight wiring harness processing, in order to avoid the wiring harness becoming skewed during the limiting process, places the wiring harness between the left and right limiting blocks, and then rotates the bidirectional threaded rod to move the left and right limiting blocks towards the center of the mounting component. After the left and right limiting blocks come into contact with the outer surface of the wiring harness, the small electric telescopic rod extends to allow the pressing block to extend out of the mounting groove to further fix the wiring harness. Then, the other end of the wiring harness is fixed with a clamping assembly. This makes it easier to fix the wiring harness and prevents skew.

[0014] 2. This easy-to-fix vehicle headlight wiring harness processing tensile testing machine, in order to quickly position the wiring harness, during the test, inserts the outer surface of the wiring harness into the groove, so that the connector at the end of the wiring harness is at the top of the fixing component. This allows the wiring harness to be quickly positioned, and as the left and right limit blocks move towards the center of the mounting component, the clamping component cooperates with the fixing component to fix the wiring harness, thereby making the wiring harness more firmly limited and the test data of the equipment more accurate.

[0017] like Figures 1-4 As shown, this utility model provides a technical solution: a tensile testing machine for processing vehicle headlight wiring harnesses that is easy to fix, including a workbench 1, a clamping assembly 2 fixedly connected to the upper surface of the workbench 1, a moving device 3 fixedly connected to the upper surface of the workbench 1, the moving device 3 is composed of a motor threaded rod and a dust cover inside the housing, and a limiting assembly 4 is provided on the front of the moving device 3. The limiting assembly 4 includes a movable block 401, a connector 402, a mounting part 403, a bidirectional threaded rod 404, a guide rod 405, a placement groove 406, a left limiting block 407, a right limiting block 408, a mounting groove 409, a small electric telescopic rod 410, a pressing block 411, and an anti-slip part 412.

[0018] In this embodiment of the present invention, the movable block 401 is disposed on the front of the moving device 3. A connector 402 is fixedly connected to the bottom of the movable block 401, and an mounting component 403 is fixedly connected to the bottom of the connector 402. A bidirectional threaded rod 404 is rotatably connected to the side of the mounting component 403. A guide rod 405 is fixedly connected to the inner wall side of the mounting component 403. A placement groove 406 is provided on the inner wall side of the mounting component 403. The position of the placement groove 406 corresponds to the position of the small electric telescopic rod 410. The size of the placement groove 406 is adapted to the size of the small electric telescopic rod 410, allowing the small electric telescopic rod 410 to be inserted into the placement groove 406. A left limiting block 407 is threadedly connected to the outer surface of the bidirectional threaded rod 404. The left limiting block 407 and the right limiting block 408 are sleeved on the outer surface of the guide rod 405. The left limiting block 407 is also provided with a mounting groove 409. The small electric telescopic rod 410, pressing block 411, and anti-slip component 412 allow the left limit block 407 and right limit block 408 to move towards the center of the mounting component 403 when the bidirectional threaded rod 404 rotates. The right limit block 408 is threadedly connected to the outer surface of the bidirectional threaded rod 404. The right limit block 408 has a mounting groove 409 on its side. The small electric telescopic rod 410 is fixedly connected to the side of the right limit block 408 away from the mounting groove 409. The pressing block 411 is fixedly connected to the end of the small electric telescopic rod 410. The anti-slip component 412 is fixedly connected to the side of the pressing block 411. The anti-slip component 412 is composed of an arc-shaped strip fixedly connected to the outer surface of the convex strip. The anti-slip component 412 is evenly distributed in a linear array on the side of the pressing block 411. The anti-slip component 412 is set inside the mounting groove 409, which makes the pressing block 411 more firmly limit the wire harness.

[0019] Meanwhile, an auxiliary component 5 is provided on the upper surface of the left limiting block 407. The auxiliary component 5 includes a locking member 503, which is fixedly connected to the upper surface of the left limiting block 407. The top of the locking member 503 corresponds to the bottom of the fixing member 501, and the size of the locking member 503 is adapted to the size of the fixing member 501. The fixing member 501 is fixedly connected to the upper surface of the left limiting block 407. A groove 502 is provided on the side of the fixing member 501, and the size of the groove 502 is adapted to the size of the outer surface of the wire harness. The center of 2 corresponds to the center of the pressing block 411. This allows the outer surface of the wire harness to be inserted into the groove 502 during the experiment, so that the connector at the end of the wire harness is at the top of the fixing member 501. This allows the wire harness to be quickly positioned. As the left limiting block 407 and the right limiting block 408 move toward the center of the mounting member 403, the locking member 503 cooperates with the fixing member 501 to fix the wire harness, thereby making the wire harness more firmly limited and making the experimental data of the equipment more accurate.

[0020] In this utility model, during use, the wire harness is placed between the left limiting block 407 and the right limiting block 408, and then the bidirectional threaded rod 404 is rotated to move the left limiting block 407 and the right limiting block 408 toward the center of the mounting component 403. After the left limiting block 407 and the right limiting block 408 come into contact with the outer surface of the wire harness, the small electric telescopic rod 410 extends to allow the pressing block 411 to extend out of the mounting groove 409 to further fix the wire harness. Then, the other end of the wire harness is fixed with the clamping component 2, which makes it easier to fix the wire harness.

[0021] Furthermore, during the experiment with the wire harness, the outer surface of the wire harness is inserted into the groove 502, so that the connector at the end of the wire harness is at the top of the fixing member 501. This allows the wire harness to be quickly positioned. As the left limiting block 407 and the right limiting block 408 move towards the center of the mounting member 403, the locking member 503 cooperates with the fixing member 501 to fix the wire harness, thereby making the wire harness more firmly limited and making the experimental data of the equipment 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.
