Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness production technology, and more specifically, to a wiring harness assembly testing device for automotive wiring harness production. Background Technology

[0002] Automotive wiring harnesses are a crucial component of automotive electrical systems. They form the main network of the vehicle's circuitry, playing a vital role in connecting various parts of the vehicle. Their primary function is to transmit electrical signals and current, ensuring the normal operation of all automotive systems. They transmit operating signals and power from electrical equipment such as the engine, transmission, and steering system to the corresponding control units or actuators, thereby enabling information exchange and coordinated operation between different parts of the vehicle.

[0003] To ensure the accuracy of signal transmission and control, and to prevent signal transmission obstruction that could affect the normal functioning of the vehicle or even cause safety accidents, it is usually necessary to inspect the wiring harness assembly. Currently, tensile testing is commonly performed on the wiring harness to ensure its reliability. Through tensile testing, it is possible to determine whether the wiring harness connection is tight and to detect the reliability of the wiring harness insulation layer, thus avoiding safety hazards such as electrical short circuits and leakage, and protecting the safe operation of the vehicle's circuitry and electrical components.

[0004] Currently, when performing tensile testing, both ends of the wire harness need to be fixed separately. At this time, one end of the wire harness is connected to the tensile sensor, and the test is achieved by applying tension to the other end. Before the test, fixing the wire harness is time-consuming and labor-intensive. It is difficult to fix wire harnesses of different diameters multiple times when testing multiple wire harness samples. Therefore, it needs to be improved and optimized. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a wiring harness assembly testing device for automotive wiring harness production, which has the advantage of high testing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wiring harness assembly testing device for automotive wiring harness production, comprising a fixed base, a platform fixedly installed on the right side of the fixed base, a control console fixedly installed on the top of the platform, a tensile detector provided on the top right side of the fixed base, and the tensile detector and the fixed base being fixedly connected by bolts.

[0007] A partition is fixedly installed on the top of the fixed base. A first limiting groove is opened inside the partition. A lead screw is rotatably installed inside the first limiting groove. A first motor is fixedly installed on the outer wall of the first limiting groove. The output shaft of the first motor is fixedly connected to the lead screw. Fixed chambers are movably installed on both the left and right sides of the top of the fixed base. The left fixed chamber is movably installed inside the first limiting groove and threadedly connected to the lead screw.

[0008] The fixed chamber is equipped with a worm gear that rotates inside. The outer wall of the fixed chamber has a vertical groove. The worm gear has an arc-shaped groove inside. A transmission rod is movably installed inside the vertical groove. One end of the transmission rod passes through the arc-shaped groove and is fixedly installed with a clamping block.

[0009] As a preferred technical solution of this utility model, a mounting column is fixedly installed on the right side wall of the fixed chamber on the right, and a connecting sleeve is fixedly installed on the left side wall of the tensile detector, and the mounting column and the connecting sleeve are sleeved together.

[0010] The mounting column has an internal telescopic groove, and a mounting block is movable inside the telescopic groove. The bottom of the mounting block and the inner wall of the telescopic groove are elastically connected by a spring.

[0011] As a preferred technical solution of this utility model, the top of the fixed base is provided with a second limiting groove, and both sets of fixed chambers are movably installed inside the second limiting groove.

[0012] In a preferred embodiment of this invention, the arc-shaped groove and the vertical groove are positioned in opposite directions and are of the same number.

[0013] As a preferred embodiment of this utility model, a worm gear is rotatably installed inside the fixed chamber, and the worm gear is connected to a worm wheel via a transmission. A second motor is fixedly installed on the outer wall of the fixed chamber, and the output shaft of the second motor is fixedly connected to the worm gear.

[0014] As a preferred embodiment of this utility model, the outer wall of the connecting sleeve is provided with an installation groove, and the installation block penetrates into the interior of the installation groove and fixes the connecting sleeve and the installation column.

[0015] As a preferred embodiment of this utility model, the mounting block is in the shape of a right trapezoid, and the inclined surface of the mounting block is opened to the right.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model uses the rotation of a worm gear to rotate a worm wheel. The rotation of the worm wheel, through the transmission of an arc-shaped groove, causes four sets of clamping blocks to clamp the outer wall of the wire harness. Finally, the operation of the first motor pulls the left end of the wire harness to complete the tensile testing. Compared with traditional devices, this device can clamp the wire harness by the synchronous inward movement of the clamping blocks, which is convenient for fixing wire harnesses of different diameters, improving the testing efficiency and reducing the workload.

[0018] 2. This utility model cancels the fixed relationship between the mounting column and the connecting sleeve by pressing the mounting block downwards. Then, by releasing the mounting block, the elastic potential energy of the expansion groove allows the mounting block to reset, thus fixing the mounting column and the connecting sleeve again. Compared with traditional devices, this device allows the tensile tester to be easily removed after the test is completed, which is convenient for storage and maintenance, reduces the disassembly burden, and improves the applicability of the device.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 7 As shown, this utility model provides a wiring harness assembly testing device for automotive wiring harness production, including a fixed base 1, a platform 2 fixedly installed on the right side of the fixed base 1, a control console 3 fixedly installed on the top of the platform 2, a tensile detector 4 provided on the top right side of the fixed base 1, and the tensile detector 4 and the fixed base 1 are fixedly connected by bolts 5.

[0029] A partition plate 6 is fixedly installed on the top of the fixed base 1. A first limiting groove 7 is opened inside the partition plate 6. A lead screw 8 is rotatably installed inside the first limiting groove 7. A first motor 9 is fixedly installed on the outer wall of the first limiting groove 7. The output shaft of the first motor 9 is fixedly connected to the lead screw 8. Fixed chambers 10 are movably installed on both the left and right sides of the top of the fixed base 1. The left fixed chamber 10 is movably installed inside the first limiting groove 7 and threadedly connected to the lead screw 8.

[0030] The fixed chamber 10 has a worm gear 14 rotatably installed inside. The outer wall of the fixed chamber 10 has a vertical groove 12. The worm gear 14 has an arc groove 15 inside. A transmission rod 13 is movably installed inside the vertical groove 12. One end of the transmission rod 13 passes through the arc groove 15 and is fixedly installed with a clamping block 16.

[0031] When the wire harness needs to be inspected, the operator first places the left and right ends of the wire harness inside the fixed compartment 10, then starts the second motor 18. The output shaft of the second motor 18 drives the worm gear 17 to rotate, which in turn drives the worm wheel 14 to rotate. The rotation of the worm wheel 14 causes the arc groove 15 to move, and the transmission rod 13 inside the arc groove 15 is pushed by the displacement of the arc groove 15. The other end of the transmission rod 13 is movably installed inside the vertical groove 12, so that the displacement of the transmission rod 13 is restricted by the vertical groove 12. Furthermore, the four sets of transmission rods 13 drive the clamping mechanism. Block 16 clamps the wire harness inward, at which point both ends of the wire harness are fixed. The operator starts the first motor 9, and the operation of the first motor 9 drives the lead screw 8 to rotate. At this time, the lead screw 8 drives the fixed chamber 10, which is threadedly connected to it, to move. It is worth noting that the right fixed chamber 10 and the lead screw 8 are threadedly connected, while the left fixed chamber 10 is movably installed inside the second limiting groove 11. At this time, the fixed chamber 10 moves to the left along the first limiting groove 7, straightening the wire harness. Furthermore, the right fixed chamber 10 is pulled by the wire harness, so that the tension detector 4 completes the detection operation.

[0032] The rotation of the worm gear 17 causes the worm wheel 14 to rotate. The rotation of the worm wheel 14 is transmitted through the arc groove 15, causing the four sets of clamping blocks 16 to clamp the outer wall of the wire harness. Finally, the operation of the first motor 9 pulls the left end of the wire harness to complete the tensile test. Compared with the traditional device, this device can clamp the wire harness by moving the clamping blocks 16 inward synchronously, which is convenient for fixing wire harnesses of different diameters, improving the efficiency of the test and reducing the workload.

[0033] Among them, the right side wall of the right fixed compartment 10 is fixedly installed with a mounting column 19, and the left side wall of the tension detector 4 is fixedly installed with a connecting sleeve 20. The mounting column 19 and the connecting sleeve 20 are nested together.

[0034] The mounting column 19 has an internal telescopic groove 22, and a mounting block 23 is movable inside the telescopic groove 22. The bottom of the mounting block 23 and the inner wall of the telescopic groove 22 are elastically connected by a spring 24.

[0035] After the test is completed, when the tension detector 4 needs to be disassembled, the operator first rotates the bolt 5 to release the fixed relationship between the tension detector 4 and the fixed seat 1. Then, the operator presses down the mounting block 23, and the mounting block 23 is retracted into the telescopic groove 22, allowing the operator to remove the tension detector 4. When the tension detector 4 needs to be installed, the operator only needs to put the connecting sleeve 20 on the outer wall of the mounting column 19. During the fitting, the inclined surface of the mounting block 23 will be pressed into the telescopic groove 22 by the outer wall of the connecting sleeve 20. After the fitting is completed, the mounting block 23 will be reset upward by the elastic potential energy of the spring 24, further completing the connection between the mounting column 19 and the connecting sleeve 20.

[0036] By pressing the mounting block 23 downwards, the fixed relationship between the mounting post 19 and the connecting sleeve 20 is canceled. Then, by releasing the mounting block 23, the elastic potential energy of the mounting block 23 is restored, allowing the mounting block 23 to fix the mounting post 19 and the connecting sleeve 20 again. Compared with traditional devices, this device can easily remove the tensile tester 4 after the test is completed, which is convenient for storage and maintenance, reduces the disassembly burden, and improves the applicability of the device.

[0037] The top of the fixed base 1 is provided with a second limiting groove 11, and both sets of fixed chambers 10 are movably installed inside the second limiting groove 11.

[0038] The left fixed chamber 10 slides along the second limiting groove 11 to provide tension. The right fixed chamber 10 can also slide along the second limiting groove 11. However, the right fixed chamber 10 is fixed between the mounting column 19 and the tension detector 4, so that the right fixed chamber 10 provides tension to the tension detector 4 to achieve detection.

[0039] The arc-shaped groove 15 and the vertical groove 12 are in corresponding positions and have the same number.

[0040] The arc-shaped groove 15 is responsible for providing power, while the vertical groove 12 is responsible for limiting the movement of the transmission rod 13.

[0041] The fixed chamber 10 has a worm gear 17 rotatably mounted inside, and the worm gear 17 is connected to the worm wheel 14. The outer wall of the fixed chamber 10 is fixedly mounted with a second motor 18, and the output shaft of the second motor 18 is fixedly connected to the worm gear 17.

[0042] The operation of the second motor 18 drives the worm gear 17 to rotate, providing power to the worm wheel 14.

[0043] The outer wall of the connecting sleeve 20 is provided with an installation groove 21, and the installation block 23 penetrates into the interior of the installation groove 21 and fixes the connecting sleeve 20 and the installation post 19.

[0044] Workers can press the mounting block 23 downward through the mounting slot 21.

[0045] The mounting block 23 is a right trapezoid, and the inclined surface of the mounting block 23 is opened to the right.

[0046] The trapezoidal design of the mounting block 23 enables unidirectional fixation.

[0047] Working principle and usage process of this utility model:

[0048] When the wire harness needs to be inspected, the operator first places the left and right ends of the wire harness inside the fixed compartment 10, then starts the second motor 18. The output shaft of the second motor 18 drives the worm gear 17 to rotate, which in turn drives the worm wheel 14 to rotate. The rotation of the worm wheel 14 causes the arc groove 15 to move, and the transmission rod 13 inside the arc groove 15 is pushed by the displacement of the arc groove 15. The other end of the transmission rod 13 is movably installed inside the vertical groove 12, so that the displacement of the transmission rod 13 is restricted by the vertical groove 12. Furthermore, the four sets of transmission rods 13 drive the clamping mechanism. Block 16 clamps the wire harness inward, at which point both ends of the wire harness are fixed. The operator starts the first motor 9, and the operation of the first motor 9 drives the lead screw 8 to rotate. At this time, the lead screw 8 drives the fixed chamber 10, which is threadedly connected to it, to move. It is worth noting that the right fixed chamber 10 and the lead screw 8 are threadedly connected, while the left fixed chamber 10 is movably installed inside the second limiting groove 11. At this time, the fixed chamber 10 moves to the left along the first limiting groove 7, straightening the wire harness. Furthermore, the right fixed chamber 10 is pulled by the wire harness, so that the tension detector 4 completes the detection operation.

[0049] After the test is completed, when the tension detector 4 needs to be disassembled, the operator first rotates the bolt 5 to release the fixed relationship between the tension detector 4 and the fixed seat 1. Then, the operator presses down the mounting block 23, and the mounting block 23 is retracted into the telescopic groove 22, allowing the operator to remove the tension detector 4. When the tension detector 4 needs to be installed, the operator only needs to put the connecting sleeve 20 on the outer wall of the mounting column 19. During the fitting, the inclined surface of the mounting block 23 will be pressed into the telescopic groove 22 by the outer wall of the connecting sleeve 20. After the fitting is completed, the mounting block 23 will be reset upward by the elastic potential energy of the spring 24, further completing the connection between the mounting column 19 and the connecting sleeve 20.
