Description

Technical Field

[0001] The invention relates to a wire harness detection technology, and in particular to an automobile wire harness detection device. Background Art

[0002] The wiring harness is a component required to interconnect all electrical and electronic components in a vehicle. During the production process of automotive wiring harnesses, a number of tests are required, including a pull-out test after the conductor of the wiring harness is crimped to the terminal. The existing method is generally to fix the terminal on a tensile gauge and fix the wiring harness part, and move the wiring harness or the tensile gauge in one direction until the wiring harness is disconnected from the terminal connection part or is not disconnected when the required force is reached. The force change during the process is recorded by the tensile gauge to determine whether it meets the requirements.

[0003] However, this test often considers the situation when the wire harness is actually used and is subjected to axial force along the wire harness. After the wire harness is crimped to the terminal, it is inevitable that the wire harness will be twisted in the radial direction during the later line arrangement and laying in the vehicle body, such as the twisting of the wire harness caused by winding the insulating tape, sleeve sleeve, cable tie binding, terminal plugging, etc., thereby generating a certain torque at the crimping part between the conductor and the terminal of the wire harness, which may cause a certain offset at the connection between the terminal and the wire skin of the wire harness or the conductor and the terminal, resulting in poor terminal crimping. When the wire harness receives axial tension and radial torque, the force required to disconnect the two is not necessarily greater than the required value. Therefore, only the axial pull-out test results cannot fully reflect the reliability of the wire harness when used in the actual environment. The existing test method has certain limitations. Therefore, it is necessary to perform corresponding tests on the wire harness under the above environment to ensure the reliability of the test results and improve the connection stability of the wire harness during actual use, especially some wire harnesses connected to key equipment of the vehicle body.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Example:

[0034] See also Figure 1 - Figure 6 , an automobile wiring harness detection device, comprising a base 1, and further comprising:

[0035] The mobile platform 2 is arranged on one side of the base 1.

[0036] A driving mechanism 3, used for driving the mobile platform 2 to move along a first direction;

[0037] A first rotating shaft 4, which is disposed on the mobile platform 2, and whose axis is parallel to the first direction;

[0038] A rotating mechanism 5, which is used to drive the first rotating shaft 4 to rotate with its central axis as the rotating axis;

[0039] A first clamp 6, which is fixedly mounted on one end of the first rotating shaft 4;

[0040] The fixed platform 7 is arranged on one side of the moving platform 2 . The fixed platform 7 is provided with a measuring component 8 . One side of the measuring component 8 is connected to a second fixture 9 .

[0041] The first clamp 6 is used to clamp the wire skin surface of the wire harness, the second clamp 9 is used to clamp the terminal of the wire harness, and the measuring component 8 is used to measure the force change when the terminal is separated from the conductor of the wire harness. It can be a commonly used tensile gauge or a tensile sensor connected to an external computer. The first clamp 6, the second clamp 9 and the measuring component 8 are all common knowledge in the prior art and are directly applied without modification. Therefore, they are not described in detail in this technical solution, and will not cause trouble to this technical solution based on the art;

[0042] In one embodiment of the present invention, the position where the first clamp 6 clamps the wiring harness depends on the position to be tested, that is, the distance between the clamping point and the terminal during the test. When performing the test, the distance needs to be recorded as test data.

[0043] In one embodiment of the present invention, the driving mechanism 3 includes a track, a slider is slidably connected to the track, one side of the slider is fixedly connected to one side of the mobile platform 2, a threaded sleeve is fixed on one side of the mobile slide, a third threaded rod is threadedly connected to the inner wall of the threaded sleeve, the third threaded rod is arranged along the first direction, and is rotatably installed on one side of the base 1, and one end of the third threaded rod is connected to the output end of the motor (not shown in the figure).

[0044] In one embodiment of the present invention, the rotating mechanism 5 includes a first gear 51, the inner wall of the first gear 51 is fixedly connected to the surface of the first rotating shaft 4, one side of the first gear 51 is meshedly connected to a first rack 52, and the length direction of the first rack 52 is perpendicular to the first direction;

[0045] In one embodiment of the present invention, a support platform 21 is fixedly connected to one side of the mobile platform 2, and two support seats 22 are arranged on the side of the support platform 21 away from the mobile platform 2. The surface of the first rotating shaft 4 is rotatably connected to the inner wall of the support seat 22, and a first sliding groove 23 is provided on one side of the support platform 21. The first sliding groove 23 is slidably connected to one side of the first rack 52. When the first rack 52 moves, the first gear 51 is driven to move, thereby rotating the first rotating shaft 4.

[0046] In one embodiment of the present invention, a second pointer 41 is fixedly connected to one end of the first rotating shaft 4 away from the first clamp 6, a second dial 42 is provided on one side of the second pointer 41, one side of the second dial 42 is fixedly connected to one side of the support platform 21, and the second pointer 41 is used to indicate the rotation angle of the first rotating shaft 4, so as to obtain test data when the terminal is separated from the wiring harness when the deflection angle changes;

[0047] It should be noted that the center of the second dial 42 coincides with the axis of the first rotating shaft 4, and the second dial 42 can also be rotatably mounted on the fixed seat 55, so that the second dial 42 can rotate around the axis of the first rotating shaft 4. When the second pointer 41 is in a random position, the second dial 42 can be rotated so that its zero scale line is always located at the indicated position of the second pointer 41, thereby avoiding deviations or confusion in recording when the tester reads the initial position of the scale, and facilitating recording and adjustment.

[0048] In one embodiment of the present invention, the rotating structure further includes an adjusting rod 53, a steering block 54 is slidably connected to the surface of the adjusting rod 53, one side of the steering block 54 is rotatably connected to one end of the first rack 52, and the length direction of the adjusting rod 53 and the projection of the length direction of the first rack 52 on the plane where the mobile platform 2 is located have an angle;

[0049] When the first rack 52 and the adjusting rod 53 move relative to each other, the moving direction of the steering block 54 can be constrained so that the steering block 54 has a component along the first direction and a component along the length direction of the first rack 52 when it moves relative to the first rack 52, so that the first rack 52 can move along its length direction, and when it moves, it drives the first gear 51 to rotate, so that the first rotating shaft 4 rotates a certain angle, so as to facilitate the pull-out force test under the condition of the harness being twisted;

[0050] In one embodiment of the present invention, a fixed seat 55 is provided at one end of the adjusting rod 53, and an adjusting member 56 is provided on the top of the fixing seat 55. One side of the adjusting member 56 is connected to one end of the adjusting rod 53. The adjusting member 56 is used to adjust the size of the angle. By changing the angle between the projection of the length direction of the adjusting rod 53 and the length direction of the first rack 52 on the plane where the moving platform 2 is located, the stroke of the steering block 54 in the length direction of the first rack 52 is changed, and the torsion angle of the first gear 51 is changed, so as to obtain an adjustable torsion angle for testing the wiring harness.

[0051] In one embodiment of the present invention, a first platform 57 and a second platform 58 are provided on one side of the fixed seat 55, one side of the first platform 57 is fixedly connected to one side of the mobile platform 2, and the second platform 58 is fixedly connected to the base 1. A second slide groove 571 is provided through one side of the first platform 57 in the vertical direction, and a third slide groove 581 is provided through one side of the second platform 58 in the vertical direction. The fixed seat 55 is slidably connected to the first slide groove 23 and the second slide groove 571, and a first guide rod 572 and a second guide rod 582 are fixedly connected in the second slide groove 571 and the third slide groove 581, respectively. One end of the first guide rod 572 penetrates the fixed seat 55 and is slidably connected to the inner wall of the fixed seat 55, and one end of the second guide rod 582 penetrates the fixed seat 55 and is slidably connected to the inner wall of the fixed seat 55;

[0052] In one embodiment of the present invention, a limiting assembly 59 is provided on one side of the fixing seat 55. The limiting assembly 59 includes a first state and a second state. In the first state, the fixing seat 55 is limited from sliding along the second slide groove 571, and the fixing seat 55 can slide along the third slide groove 581. In the second state, the fixing seat 55 is limited from sliding along the third slide groove 581, and the fixing seat 55 can slide along the second slide groove 571.

[0053] In one embodiment of the present invention, in order to prevent the fixing seat 55 from being blocked from moving due to the installation size deviation between the first platform 57 and the second platform 58 when the fixing seat 55 slides with the second slide groove 571 or the third slide groove 581, the fixing seat 55 can also be a split type, which is composed of a first part 551 and a second part 552, such as Figure 6 As shown, a slide column 553 is slidably installed between the first part 551 and the second part 552. When the parallelism of the installation of the first platform 57 and the second platform 58 is poor, the setting of the slide column 553 can avoid obstruction of the movement of the fixing seat 55, thereby improving the smoothness of the device.

[0054] When the limit assembly 59 is in the first state, the fixed seat 55 is only fixed in the second slide groove 571. At this time, the mobile platform 2 drives the first platform 57 to move and drives the fixed seat 55 to move together. The fixed seat 55 can slide in the third slide groove 581. When testing the wiring harness, the fixed seat 55 and the mobile platform 2 are in a relatively static state. At this time, the tests that can be performed include: performing a conventional pull-out force test when the wiring harness is not twisted, or performing a pull-out force test after the wiring harness is twisted by a certain angle first;

[0055] When the limit assembly 59 is in the first state, the fixed seat 55 is only fixed on the third slide groove 581. At this time, the mobile platform 2 does not drive the fixed seat 55 to move together when it moves, and the fixed seat 55 slides in the second slide groove 571. When testing, the fixed seat 55 and the mobile platform 2 are in a state of relative motion, that is, when the mobile platform 2 moves at this time, the fixed seat 55 is in a prohibited state. When the steering block 54 moves on the adjustment rod 53, it drives the first rack 52 to move, thereby driving the wiring harness to twist. The contents that can be tested include: a pulling force test when the pulling force and the twisting force act simultaneously between the wiring harness and the terminal;

[0056] In one embodiment of the present invention, the limiting assembly 59 includes two limiting members, the limiting members include a first threaded rod 591, a first limiting groove 573 and a second limiting groove 583 are respectively opened on one side of the first platform 57 and the second platform 58, the two first threaded rods 591 are respectively slidably connected with the first limiting groove 573 and the second limiting groove 583, the ends of the first threaded rods 591 are both threadedly connected with a first locking nut 592, and one end of the two first threaded rods 591 is respectively fixedly connected to one side of the fixing seat 55;

[0057] By rotating the first locking nut 592 or the second locking nut 562 , the first locking nut 592 or the second locking nut 562 can be pressed against the side of the first platform 57 or the second platform 58 , respectively, so that the limiting assembly 59 is in the first state or the second state.

[0058] In one embodiment of the present invention, the adjusting member 56 includes a second threaded rod 561 and a second locking nut 562, one end of the second threaded rod 561 is fixedly connected to one end of the fixing seat 55, one end of the adjusting rod 53 is rotatably connected to the inner wall of the second threaded rod 561, the end of the second threaded rod 561 is threadedly connected to the second locking nut 562, one side of the fixing seat 55 is fixedly connected to a first dial 563, one end of the adjusting rod 53 is fixedly connected to a first pointer 564, and the direction indicated by the first pointer 564 is parallel to the axial direction of the adjusting rod 53;

[0059] By rotating the second locking nut 562, the end of the adjusting rod 53 is fixed at a set position by the second locking nut 562, thereby facilitating adjustment of the angle between the adjusting rod 53 and the first rack 52, so that when the mobile platform 2 moves the same distance during testing, the different angles cause the first rotating shaft 4 to twist at different angles.

[0060] In one embodiment of the present invention, a conventional pull-out test method without torsion is provided, which specifically comprises the following steps:

[0061] S101, first fix the fixing seat 55 in the second sliding groove 571 through the limiting assembly 59, that is, the limiting assembly 59 is in the first state;

[0062] S102, clamping the terminal at one end of the wiring harness to be tested on the second clamp 9, moving the movable platform 2 to a suitable position, clamping the surface of the wiring harness by the first clamp 6, and making the wiring harness in a relaxed state before testing;

[0063] S103, driving the mobile platform 2 to move away from the second fixture 9 at a certain speed through the driving mechanism 3, and the measuring component 8 will record the force conditions during the pulling in real time;

[0064] S104. Analyze the stress conditions to obtain the value of the pull-out force when the wire harness is separated from the terminal.

[0065] It should be noted that when a tensile gauge is used to record data, the recording method can be set to display the maximum value, and the value when the force is maximum during the pulling process is used as the pulling force when the wire harness and the terminal fail to separate. When a tensile sensor and corresponding software are used for recording, the real-time data of the sensor force can be recorded to obtain the change in force when the terminal is separated from the wire harness during the pulling test.

[0066] In one embodiment of the present invention, a conventional pull-out test method for torsion is provided, which specifically comprises the following steps:

[0067] S201, adjusting the limit assembly 59 so that the limit assembly 59 is initially in a first state;

[0068] S202, first clamp the terminal at one end of the wiring harness to be tested on the second clamp 9, move the mobile platform 2 to a suitable position, clamp the surface of the wiring harness by the first clamp 6, and move the mobile platform 2 until the wiring harness is in a slightly tightened state;

[0069] S203, releasing the clamping of the second clamp 9 on the terminal;

[0070] S204, adjusting the limit assembly 59 to put the limit assembly 59 in the second state, driving the mobile platform 2 to move a certain distance toward one side of the second fixture 9, so that the first rotating shaft 4 rotates to a desired angle;

[0071] S205, clamping the terminal of the wiring harness again by the second clamp 9, and making sure that the wiring harness is not twisted before clamping;

[0072] S206, driving the mobile platform 2 to move away from the second clamp 9 through the driving mechanism 3, and recording the force conditions during pulling in real time through the measuring component 8 to obtain the pulling force data when the pulling force and the torsional force exist simultaneously.

[0073] It should be noted that, initially, the fixing seat 55 should be located near the middle of the second slide groove 571. During the test, as the mobile platform 2 moves, the tension on the wiring harness and the terminal continues to increase. At the same time, the torque applied to the wiring harness also continues to increase. This is to simulate the situation in which the wiring harness is separated from the terminal when it is assembled or used and receives continuous tension and torque, thereby obtaining an effect of a torque that continuously acts on the wiring harness and continuously increases on the connection state of the wiring harness and the terminal. It should be understood that an increase in torque means an increase in the torsion angle of the wiring harness.

[0074] In one embodiment of the present invention, another conventional pull-out test method for twisting is provided, which is different from the above in that it is a pull-out test when the test harness has been twisted to a certain extent but the twisting angle will not increase, specifically comprising the following steps:

[0075] S301, adjusting the limit assembly 59 so that the limit assembly 59 is initially in a first state;

[0076] S302, firstly clamp the terminal at one end of the wire harness to be tested on the second clamp 9, the first clamp 6 clamps the surface of the wire harness, and the mobile platform 2 moves until the wire harness is in a relaxed state;

[0077] S303, adjusting the limit assembly 59 to put it in the second state, driving the mobile platform 2 away from the second fixture 9, twisting the wire harness by a specified angle, and then adjusting the limit assembly 59 again to put it in the first state, and at this time the wire harness is still in a relatively loose state;

[0078] S304, driving the mobile platform 2 to move away from the second clamp 9 through the driving mechanism 3, and recording the force conditions during pulling in real time through the measuring component 8 to obtain the pulling force data when the torsion angle is fixed.

[0079] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
