Description

Technical Field

[0001] The utility model relates to the field of automobile wire harness detection, and particularly relates to an automobile wire harness detection device. Background Art

[0002] An automobile wire harness is composed of a wire harness body and terminals. According to the requirements of national standards, there are certain requirements for the pressing force when the wire harness body is pressed tightly on the terminals. That is to say, after the wire harness body and the terminals are pressed tightly, they will not be pulled off under a certain pulling force. If the requirements are not met, it means that the tensile strength of the wire harness body and the terminals is unqualified. Such an automobile wire harness is prone to the hidden danger of wire disconnection under the action of external forces, resulting in the abnormal operation of electrical appliances. When recycling scrapped automobiles, many wire harness bodies often have not reached the service life and have the value of being reused. Therefore, when recycling scrapped automobiles, the automobile wire harness can be detected, and the qualified wire harness bodies can be reused. At present, the tensile force detection of the wire harness body and the terminals is mostly carried out manually by workers using a peak tensile force meter, which not only has low detection efficiency but also has large errors in detection results.

[0034] Reference Figure 1 and Figure 2 As shown, an automobile wire harness detection device according to an embodiment of the utility model comprises: a frame 100 , a pulling mechanism 200 , and a limiting seat 400 .

[0035] The pulling mechanism 200 is disposed on the frame 100 and includes a clamping seat 210 and a driving member 220 which are transmission-connected. The clamping seat 210 is used to clamp and fix one end of the wiring harness body 300 , and the driving member 220 is used to drive the clamping seat 210 to move along the first direction.

[0036] The limit seat 400 is arranged on the frame 100. The limit seat 400 and the clamping seat 210 are distributed oppositely along the first direction, that is, the limit seat 400 and the clamping seat 210 are respectively located on the opposite sides of the frame 100 along the first direction. A limit mechanism 410 is arranged on the limit seat 400. The limit mechanism 410 is used to abut against the terminal 310 and limit the displacement of the terminal 310 along the first direction towards the clamping seat 210. Obviously, the limit mechanism 410 can be adjusted to release the limit on the terminal 310.

[0037] During use, one end of the wire harness body 300 is fixed by the clamping seat 210, and then the terminal 310 at the other end of the wire harness body 300 is placed on the limit seat 400. The limit mechanism 410 is used to abut against the terminal 310 to limit the displacement of the terminal 310 along the first direction towards the clamping seat 210. Then, the driving part 220 is started, and the driving part 220 is used to drive the clamping seat 210 to move away from the limit seat 400 along the first direction, so as to pull the wire harness body 300 away from the terminal 310 along the first direction, realizing the tensile force detection between the terminal 310 and the wire harness body 300. Compared with manual detection, the detection efficiency is high and the detection accuracy is high.

[0038] In some specific embodiments, the driving part 220 is set as a hydraulic cylinder.

[0039] Refer to Figure 1 and Figure 2 As shown, it can be understood that the clamping seat 210 includes a fixed seat 230 and a pressing seat 240. The fixed seat 230 is connected to the output end of the driving part 220. An abutting surface is arranged on the fixed seat 230. The pressing seat 240 is arranged on one side of the fixed seat 230 and can move close to or away from the abutting surface. The side of the pressing seat 240 facing the abutting surface is adapted to the abutting surface. A pressing mechanism is arranged on the fixed seat 230. The pressing mechanism is used to abut against and push the pressing seat 240 to move close to the abutting surface so that the pressing seat 240 cooperates with the abutting surface to clamp the wire harness body 300, thereby clamping and fixing one end of the wire harness body 300. The structure is simple and practical.

[0040] Among them, the abutting surface includes a first abutting surface 231 and a second abutting surface 232 that form an angle with each other. The pressing seat 240 is configured to be able to cooperate with the first abutting surface 231 and the second abutting surface 232 to clamp the wire harness body 300 and bend the wire harness body 300. Obviously, if the wire harness body 300 is in a straight state after the pressing seat 240 cooperates with the abutting surface to clamp the wire harness body 300, the wire harness body 300 is relatively easy to slide between the pressing seat 240 and the abutting surface, affecting the accuracy of the tensile force detection. By setting the abutting surface to include the first abutting surface 231 and the second abutting surface 232 that form an angle with each other, and using the pressing seat 240 to cooperate with the first abutting surface 231 and the second abutting surface 232 to bend the wire harness body 300, the wire harness body 300 can be clamped more firmly, and the wire harness body 300 is not easy to slide between the pressing seat 240 and the abutting surface. The structure is reliable and the detection error is small. Obviously, the bending angle of the wire harness body 300 is the angle between the first abutting surface 231 and the second abutting surface 232.

[0041] In some specific embodiments, the first abutting surface 231 is perpendicular to the second abutting surface 232, which is convenient for processing. The second abutting surface 232 is located at one end of the first abutting surface 231 away from the limiting seat 400. The normal direction of the second abutting surface 232 is parallel to the first direction. The pressing seat 240 is provided with a first pressing surface 241 parallel to the first abutting surface 231 and a second pressing surface 242 parallel to the second abutting surface 232. The first pressing surface 241 is used to cooperate with the first abutting surface 231 to clamp the wire harness body 300, and the second pressing surface 242 is used to cooperate with the second abutting surface 232 to clamp the wire harness body 300. Obviously, the wire harness body 300 clamped between the first abutting surface 231 and the first pressing surface 241 is distributed along the first direction. When pulling the wire harness body 300 for tensile force detection, the detection error can be reduced. It can be understood that in order to enable the first abutting surface 231 to cooperate with the first pressing surface 241 to clamp the wire harness body 300, and at the same time the second abutting surface 232 can also cooperate with the second pressing surface 242 to clamp the wire harness body 300, the moving path of the pressing seat 240 is located on the angular bisector plane of the first abutting surface 231 and the second abutting surface 232, ensuring that during the movement of the pressing seat 240, the distance between the first abutting surface 231 and the first pressing surface 241 is always equal to the distance between the second abutting surface 232 and the second pressing surface 242.

[0042] Furthermore, there is an arc transition between the first abutting surface 231 and the second abutting surface 232, and an arc transition between the first pressing surface 241 and the second pressing surface 242 to avoid damage to the wire harness body 300 after bending.

[0043] Refer to Figure 1 and Figure 2As shown, it can be understood that the pressing seat 240 is slidably arranged on the fixed seat 230. The pressing mechanism includes a pressing screw 250 threadedly installed on the fixed seat 230. The pressing screw 250 is located on the side of the pressing seat 240 away from the abutting surface and is used to abut against and push the pressing seat 240 to move close to the abutting surface. The structure is simple and the operation is convenient. Only by screwing the pressing screw 250 can the clamping and loosening of the wire harness body 300 be realized. It can be understood that an operation handle is arranged at one end of the pressing screw 250 away from the pressing seat 240 to facilitate the operator to screw the pressing screw 250. Further, a threaded mounting seat 260 is fixedly installed on the fixed seat 230 through a fastener for installing the pressing screw 250.

[0044] In some specific embodiments, a wedge-shaped groove 233 is provided on the fixed seat 230, and a wedge-shaped block 243 is provided on the pressing seat 240. The wedge-shaped block 243 is slidably matched with the wedge-shaped groove 233 to slidably mount the pressing seat 240 on the fixed seat 230.

[0045] Refer to Figure 1 and Figure 3 As shown, it can be understood that a directional groove 401 penetrating along the first direction is provided on one side surface of the limiting seat 400. The directional groove 401 is used for one end of the wire harness body 300 to be inserted. In this way, the wire harness body 300 on the side close to the terminal 310 can be distributed along the first direction. When performing the tensile test, the deviation in direction can be avoided, ensuring the accuracy of the tensile test. It can be understood that the size of the directional groove 401 meets the condition that the terminal 310 cannot pass through the directional groove 401 along the first direction, that is, after the wire harness body 300 is inserted into the directional groove 401, the terminal 310 is located outside the directional groove 401.

[0046] Refer to Figure 1 and Figure 3As shown, it can be understood that the limiting mechanism 410 includes a limiting block 411 and an elastic member 412. The limiting block 411 is slidably disposed on the opening side of the guiding groove 401 along a second direction perpendicular to the first direction. The elastic member 412 is configured to apply an elastic force to the limiting block 411. The elastic member 412 is configured such that: in the normal state, the elastic member 412 can keep the limiting block 411 partially covering the opening of the guiding groove 401 to limit the wire harness body 300 in the guiding groove 401 and restrict the displacement of the terminal 310 along the first direction towards the clamping seat 210. Specifically, the size of the guiding groove 401 satisfies the condition that the terminal 310 cannot pass through the guiding groove 401 along the first direction. That is, after the wire harness body 300 is inserted into the guiding groove 401, the terminal 310 is located outside the guiding groove 401. On this basis, by providing the limiting block 411, the wire harness body 300 is limited in the guiding groove 401 by the limiting block 411 and the displacement of the terminal 310 along the first direction towards the clamping seat 210 is restricted, which can ensure that the terminal 310 will not break away from the limiting seat 400 and guarantee the stability during the tensile force detection. Obviously, after the detection, an acting force opposite to the elastic force of the elastic member 412 can be applied to the limiting block 411 to make the limiting block 411 slide to release the limitation on the wire harness body 300 and the terminal 310, so that the wire harness body 300 and the terminal 310 can be removed from the limiting seat 400. Just perform the reverse operation before the detection, and the operation is very convenient.

[0047] Referring to Figure 1 and Figure 3 As shown, it can be understood that a guide rod 413 is provided on the side of the limiting block 411 facing away from the guiding groove 401. The guide rod 413 is slidably inserted through the limiting seat 400 along the second direction. The elastic member 412 is provided as a compression spring and sleeved on the guide rod 413. Specifically, a detachable mounting support 420 is provided on the limiting seat 400. The guide rod 413 is slidably inserted through the mounting support 420 along the second direction. Both ends of the compression spring respectively abut against the mounting support 420 and the limiting block 411. A limiting nut 414 is threadedly connected to the guide rod 413. The limiting nut 414 is located on the side of the mounting support 420 facing away from the limiting block 411. Obviously, providing the detachable mounting support 420 can facilitate the disassembly and assembly of the limiting block 411 and the compression spring, and providing the limiting nut 414 can disassemble and assemble the two as a whole when disassembling and assembling the limiting block 411 and the compression spring, and the operation is convenient.

[0048] Referring to Figure 1 and Figure 3As shown, it can be understood that since the automotive wiring harness has various lengths and the driving stroke of the driving member 220 is limited, in order to be applicable to the tensile force detection of automotive wiring harnesses of various lengths, the following structure is provided: The limiting seat 400 is slidably arranged on the frame 100 in the first direction, and a positioning structure is provided between the frame 100 and the limiting seat 400. The positioning structure is configured to be able to fix the limiting seat 400 at multiple positions in the first direction. In this way, a variety of distances can be provided between the limiting seat 400 and the driving member 220 to be applicable to the tensile force detection of automotive wiring harnesses of various lengths.

[0049] Referring to Figure 1 and Figure 3 As shown, it can be understood that the positioning structure includes a fixing screw 500. The frame 100 is provided with mounting rods 110 distributed in the first direction. The mounting rods 110 are provided with a plurality of first positioning holes 101 arranged in the first direction. The limiting seat 400 is provided with a mounting ring sleeve 430. The mounting ring sleeve 430 is slidably sleeved on the mounting rod 110. The mounting ring sleeve 430 is provided with a second positioning hole 402. The number of the first positioning holes 101 is greater than the number of the second positioning holes 402. At least one of the first positioning hole 101 and the second positioning hole 402 is provided with internal threads. The second positioning hole 402 can be aligned with any one of the first positioning holes 101 and the fixing screw 500 is passed through to fix the limiting seat 400. Since the number of the first positioning holes 101 is greater than the number of the second positioning holes 402, the limiting seat 400 can be fixed at multiple positions in the first direction.

[0050] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
