[0002] Automotive wiring harnesses are a core component of automotive electrical systems, responsible for connecting various electronic devices and sensors. The quality of the wiring harness directly affects the safety, reliability, and performance of the vehicle. Tensile testing is a critical step in the wiring harness manufacturing process, used to ensure that the wiring harness can withstand mechanical stress during installation and use, avoiding malfunctions caused by insufficient or excessive tensile force. Currently, tensile testing of automotive wiring harnesses typically involves manually clamping and fixing the wiring harness at both ends, and then manually disassembling it after testing. This cumbersome process significantly reduces testing efficiency and cannot meet the demands of modern industry for high-efficiency testing. Therefore, this invention proposes an automatic tensile testing device for automotive wiring harnesses. Utility Model Content

[0030] Example:

[0031] like Figure 1 and Figure 2 As shown, the present invention proposes a wire harness tensile testing device, comprising: a base 1 for support, wherein the bottom surface of the base 1 is provided with a rubber anti-slip pad to increase the friction of the bottom surface contact; support plates 2 are respectively fixedly provided at both ends of the base 1, and the support plates 2 are symmetrically arranged; a threaded rod 3 is rotatably provided between the support plates 2 through a bearing; one end of the threaded rod 3 is provided with a motor 4 for driving rotation, which can drive the threaded rod 3 to rotate stably; a guide block 5 is fixedly provided on the upper surface of the base 1; one end of the guide block 5 is fixedly provided with a limit block 6, and the limit block 6 is integrally formed with the guide block 5; the limit block 6 is triangular. Structural setup: A threaded sleeve block 7 is threaded onto the outer wall of the threaded rod 3. A fixed seat 8 is fixedly installed at the upper end of the threaded sleeve block 7. A tension component 9 for automatically clamping one end of the wire harness is fixedly installed on the upper surface of the fixed seat 8, which facilitates the horizontal movement of the tension component 9 by the threaded rod 3 in conjunction with the threaded sleeve block 7. A support plate 10 is set at one end of the base 1. The support plate 10 and the fixed seat 8 are located on the same horizontal plane. The support plate 10 is fixedly connected to the support plate 2. A detection component 11 for clamping and detecting the tension of the other end of the wire harness is fixedly installed on the upper surface of the support plate 10, which can ensure that the detection component 11 and the tension component 9 are located on the same horizontal plane.

[0032] like Figures 1 to 3As shown, the tension assembly 9 includes a fixed frame 91 fixedly mounted on the upper surface of the fixed base 8. The fixed frame 91 is hollow inside, and a set of connecting plates 92 are slidably mounted inside the fixed frame 91. The connecting plates 92 have an "L"-shaped structure. A first clamping block 93 is fixedly mounted on one end of the connecting plate 92, and anti-slip grooves 15 are respectively opened on the opposite surfaces of the first clamping block 93 to increase the friction between the first clamping block 93 and the wire harness, thereby improving the stability of the clamping. A sliding guide block 94 is fixedly mounted on the other end of the connecting plate 92, and one end of the sliding guide block 94 is inclined. Furthermore, the sliding guide block 94 is slidably connected to the guide block 5 and the limiting block 6, which can ensure the trajectory of the sliding guide block 94. A set of fixed plates 95 are fixedly installed on one side of the fixed frame 91, and a guide rod 96 is fixedly installed between the fixed plates 95. The guide rod 96 is movably sleeved with the connecting plate 92, which can increase the stability of the movement of the connecting plate 92. A spring 97 is sleeved on the outer wall of the guide rod 96. One end of the spring 97 is fixedly connected to the fixed plate 95, and the other end of the spring 97 is fixedly connected to the guide rod 96, which can provide elastic force to the first clamping block 93, thereby stably clamping the wire harness.

[0033] like Figure 1 and Figure 4 As shown, the detection component 11 includes a tension sensor 111 fixedly mounted on the upper surface of the support plate 10. The tension sensor 111 is existing technology and will not be described in detail here. A connecting block 112 is fixedly mounted on the output end of the tension sensor 111. Two opposing cylinders 113 are fixedly mounted on one side of the connecting block 112. A second clamping block 114 is fixedly mounted on the output end of the cylinder 113, which can stably clamp the other end of the wire harness. Anti-slip grooves 15 are respectively opened on the opposite surfaces of the second clamping block 114 to increase the friction between the contact with the wire harness and improve the stability of clamping.

[0034] Furthermore, a set of guide rods 12 are fixedly arranged between the support plates 2. A sliding sleeve block 13 is movably sleeved on the outer wall of the guide rod 12. The upper end of the sliding sleeve block 13 is fixedly connected to the bottom surface of the fixed seat 8, which can increase the stability of the fixed seat 8, thereby improving the stability of the movement of the tension assembly 9.

[0035] Furthermore, a display panel 14 is provided on one side of the support plate 10. The display panel 14 is electrically connected to the tension sensor 111, which can quickly transmit the detected tension through the display panel 14 wire harness, making it convenient for the testing personnel to directly observe the tension.

[0036] The working principle of this embodiment is as follows: First, the two ends of the wire harness to be tested are placed between the first clamping block 93 and the second clamping block 114, respectively. Then, the motor 4 is started, and the motor 4 drives the threaded rod 3 to rotate. Because the threaded sleeve block 7 is threadedly connected to the threaded rod 3, the threaded sleeve block 7 moves along the axial direction of the threaded rod 3 when the threaded rod 3 rotates. During the movement, the fixed seat 8 moves together with the threaded sleeve block 7. The sliding guide block 94 in the tension assembly 9 on the fixed seat 8 contacts and slides with the guide block 5 and the limiting block 6 through the elastic force provided by the spring 97. One end of the sliding guide block 94 is inclined. As it slides, the connecting plate 92 causes the first clamping block 93 to move closer to each other, thereby stably clamping and pulling one end of the wire harness. This process greatly saves the wire harness fixing time.

[0037] After one end of the wire harness is clamped and fixed by the tension component 9, the other end is clamped by the second clamping block 114 controlled by the cylinder 113 in the detection component 11. At this time, the motor 4 continues to drive the threaded sleeve block 7 to move the fixing seat 8 and one end of the wire harness. As the wire harness is stretched, the tension sensor 111 in the detection component 11 starts to work, detects the tension on the wire harness in real time, and transmits the detection data to the display panel 14 for display.

[0038] After the tensile test of the automotive wiring harness is completed, the cylinder 113 in the testing assembly 11 retracts, causing the second clamping block 114 to release the wiring harness. Simultaneously, the motor 4 drives the threaded rod 3 to rotate, moving the tensile assembly 9 to its initial position. Guided by the guide block 5 and the limiting block 6, the connecting plate 92 overcomes the elastic force of the spring 97 and moves in the opposite direction on the guide rod 96. The connecting plate 92 then causes the first clamping block 93 to release the other end of the wiring harness. At this point, the operator can easily remove the tested wiring harness, greatly simplifying the disassembly process, reducing manual intervention, and lowering labor intensity. Afterwards, the motor 4 reverses, driving the threaded sleeve block 7 back to its initial position, ready for the next wiring harness test. Through this process, the equipment meets the demand for efficient testing in the rapid development of modern industry. In large-scale wiring harness testing, it can significantly reduce the testing cycle and improve overall production efficiency.

[0039] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
