Description

Technical Field

[0001] This utility model relates to the technical field of wire harness tensile testing equipment, specifically a tensile testing machine for processing automotive lamp wire harnesses that can prevent slippage. Background Technology

[0002] A wire harness is a general unit of service equipment that provides services to a certain load source group, such as a relay line, switching device, control system, etc. In daily life, the structure of multiple wires combined together is usually called a wire harness. After production, wire harnesses need to be sampled and tested for tensile strength using a wire harness tensile testing device.

[0003] According to a public announcement of a wire harness tensile testing machine drive assembly (announcement number: CN220170704U), the above application utilizes a combination of a buffer pad structure and a strip pad structure. After the wire harness breaks, the buffer pad and the strip pad are made of synthetic rubber, which has the buffering and shock-absorbing properties to reduce the impact force from the vertical plate, prevent the left side of the strip block from colliding with the right side of the pressure detector, and use a spring to reduce the impact force from the right side of the telescopic rod.

[0004] However, in actual use, the above-mentioned equipment still requires manual fixation of the vehicle light wiring harness during actual testing of its tensile strength. This greatly reduces the efficiency of the test and cannot provide a good fixation effect for the wiring harness used in processing. In view of this, we propose a tensile testing machine for processing vehicle light wiring harnesses that can avoid slippage. Summary of the Invention

[0005] The purpose of this invention is to provide a tensile testing machine for processing automotive lighting wiring harnesses that can prevent slippage, thereby solving 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 can prevent slippage includes a base, a support column fixedly connected to the upper surface of the base, a vertical groove formed on the outer surface of the support column, and a clamping mechanism disposed inside the vertical groove, the clamping mechanism comprising: The motor has its upper surface fixedly connected to the top of the vertical slot. A first threaded post is fixedly connected to the output end of the motor. A connecting block is threaded onto the outer surface of the first threaded post. A connecting post is fixedly connected through the upper surface of the connecting block. A connecting plate is fixedly connected to the lower surface of the connecting post. A clamping block is fixedly connected to the lower surface of the connecting plate. A fixing block is provided, the side wall of which is fixedly connected to the side wall of a clamping block. The side wall of the clamping block has a circular groove that matches the size of the fixing block. A movable rod is fixedly connected to the side of the fixing block near the circular groove. A telescopic spring is sleeved on the outer surface of the movable rod. A movable sleeve is sleeved on the outer surface of the telescopic spring. A clamping claw is fixedly connected to the end of the movable rod away from the fixing block.

[0007] Preferably, a fixing mechanism is provided on the outer surface of the first threaded post. The fixing mechanism includes a limiting plate. One end of the limiting plate is fixedly connected to the outer surface of the first threaded post. A control plate is fixedly connected to the side of the limiting plate away from the first threaded post. A groove is formed on the outer surface of the control plate. A second threaded post is threadedly connected to the side wall of the groove.

[0008] Preferably, a knob is fixedly connected to the end of the second threaded post away from the limiting plate, a clamping plate is fixedly connected to the end of the second threaded post away from the knob, and a locking block is fixedly connected to the side of the control plate away from the clamping plate.

[0009] Preferably, a control console is fixedly connected to the upper surface of the base, and a support foot is fixedly connected to the lower surface of the base.

[0010] Preferably, a connecting sleeve is slidably connected to the side wall of the vertical groove, one end of the connecting sleeve is fixedly connected to the end of the vertical groove, and the other end of the connecting sleeve is fixedly connected to the upper and lower ends of the connecting block.

[0011] Preferably, the clamping claws are V-shaped, and there are two sets of clamping claws. The two sets of clamping claws are distributed in a mirror image symmetrically at both ends of the movable rod away from the fixed block. One set of clamping claws is hollow, and the size of the other set of clamping claws matches the hollow.

[0012] Preferably, a rubber pad is fixedly connected to the outer surface of the clamping claw, and the end of the clamping plate away from the knob is configured as a rack shape.

[0013] Compared with the prior art, this utility model provides a tensile testing machine for processing automotive lighting wiring harnesses that can prevent slippage, and has the following beneficial effects: 1. This tensile testing machine for automotive lighting wiring harness processing, designed to prevent slippage, features a clamping mechanism. A motor drives the first threaded post to rotate, causing the connecting block and the clamping block below to move up and down. This allows for precise adjustment of the clamping claws' position. The clamping claws employ a V-shaped mirror symmetrical design, with one set being hollow and the other set matching the size of the hollow area. Combined with the elastic buffer structure of the movable rod, telescopic spring, and movable sleeve, it adapts to the shape of the wiring harness when tensile force is applied, providing dynamic clamping force. Simultaneously, the rubber pad on the outer surface of the clamping claws further enhances friction. This design effectively prevents the automotive lighting wiring harness from slipping during tensile testing, ensuring a stable and reliable testing process, improving the accuracy of test data, and enhancing equipment safety.

[0014] 2. This tensile testing machine for automotive lighting wiring harness processing, designed to prevent slippage, features a fixing mechanism, a limiting plate, and a control plate. It utilizes a second threaded post connecting the knob and a rack-shaped clamping plate to achieve rapid adjustment and locking of the wiring harness or test component. When the user rotates the knob, the second threaded post moves within the groove, pushing the clamping plate towards the locking block. The rack-shaped design enhances the clamping force. This structure simplifies the operation process, allowing for secure fixing of components without additional tools. It avoids offset or errors caused by loosening during testing, significantly improving the ease of operation and the reliability of test results. Attached Figure Description

A circular groove of matching size 27 is fixedly connected to a movable rod 28 on the side of the fixed block 27 near the circular groove. A telescopic spring 29 is sleeved on the outer surface of the movable rod 28, and a movable sleeve 210 is sleeved on the outer surface of the telescopic spring 29. A clamping claw 211 is fixedly connected to the end of the movable rod 28 away from the fixed block 27. A connecting sleeve 4 is slidably connected to the side wall of the vertical groove.

One set of clamping claws 211 is hollowed out, and the size of the other set of clamping claws 211 matches the hollowed-out area, allowing the two sets of clamping claws 211 to interlock and provide better clamping force. By providing a clamping mechanism 2, in conjunction with the motor 21 driving the first threaded post 22 to rotate, the connecting block 23 and the clamping block 26 below it move up and down, achieving precise positioning of the clamping claws 211. The clamping claws 211 are designed with a V-shaped mirror symmetry, with one set being hollow and the other set matching the size of the hollow. Combined with the elastic buffer structure of the movable rod 28, the telescopic spring 29, and the movable sleeve 210, they can adapt to the shape of the wire harness when tension is applied, providing dynamic clamping force. At the same time, the rubber pad on the outer surface of the clamping claws 211 further enhances the friction. This design effectively avoids the slippage problem of the vehicle headlight wire harness during tensile testing, ensuring a stable and reliable testing process, improving the accuracy of test data and the safety of the equipment.

[0019] Additionally, a fixing mechanism 3 is provided on the outer surface of the first threaded post 22. The fixing mechanism 3 includes a limiting plate 31, one end of which is fixedly connected to the outer surface of the first threaded post 22. A control plate 32 is fixedly connected to the side of the limiting plate 31 away from the first threaded post 22. A groove 33 is formed on the outer surface of the control plate 32. A second threaded post 34 is threadedly connected to the side wall of the groove 33. A knob 35 is fixedly connected to the end of the second threaded post 34 away from the limiting plate 31. A clamping plate 37 is fixedly connected to the end of the second threaded post 34 away from the knob 35.

By setting a fixing mechanism 3, in conjunction with the limiting plate 31 and the control plate 32, and using the second threaded post 34 to connect the knob 35 and the rack-shaped clamping plate 37, the wire harness or test component can be quickly adjusted and locked. When the user rotates the knob 35, the second threaded post 34 moves in the groove 33, pushing the clamping plate 37 to move towards the locking block 36.

A rubber pad is fixedly connected to the outer surface of the clamping claw 211, and the end of the clamping plate 37 away from the knob 35 is set as a rack shape. The rubber pad is fixedly connected to the outer surface of the clamping claw 211, which can ensure the clamping force without damaging the vehicle light wiring harness used for testing. Furthermore, by setting the end of the clamping plate 37 away from the knob 35 as a rack shape, a more stable fixing force for fixing the vehicle light wiring harness can be provided.

[0021] In this utility model, during use, when the tensile testing machine is working, the operator first places one end of the vehicle headlight wiring harness to be tested between the clamping plate 37 and the locking block 36 of the fixing mechanism 3. By rotating the knob 35, the second threaded post 34 is driven, causing the rack-shaped clamping plate 37 to move towards the locking block 36, thereby firmly clamping the wiring harness. The other end of the wiring harness is placed between the two sets of V-shaped clamping claws 211 of the clamping mechanism 2. The rubber pads on the surface of the clamping claws 211 and their mirror-symmetrical and interlocking hollow design make one set of clamping claws 211 It can be inserted into the gap of another set of clamping claws 211, and adaptively bites the wire harness under the action of the telescopic spring 29, providing anti-slip clamping force. The start motor 21 drives the first threaded post 22 to rotate, which drives the threaded connecting block 23 to move up and down along the vertical groove. Then, the connecting post 24, connecting plate 25 and clamping block 26 pull the movable rod 28 and clamping claws 211 to apply a controllable tension to the wire harness for testing. The connecting sleeve 4 provides protection for the first threaded post 22. The test status and data are monitored and recorded by the control console 13.
