Description

Technical Field

[0001] The invention relates to the technical field of automobile wire harness production and testing equipment, in particular to an automobile wire harness testing device. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The automotive wiring harness consists of wires, connectors, protective sleeves and positioning parts, which play the role of connection and power supply, ensuring the normal operation of the vehicle and various electronic devices. During the production process of automotive wiring harnesses, testing the strength of the wiring harness connection terminals is an important step in the quality inspection of the wiring harness.

[0003] The prior art has the following deficiencies: the prior art publication number CN118409239A states that “a vehicle wiring harness detection device” “includes a detection platform, and also includes: a detection rotating block arranged on the top of the detection platform, and an adjacent side of the detection rotating block is provided with an energized plug-in slot, and the energized plug-in slot is used to plug in the vehicle wiring harness.”

[0004] The above structure can make the detection semicircular ring move back and forth along the outer surface of the automobile wiring harness through the setting of the threaded rotating rod, the movable groove and the limit slide, but the structure does not improve the tensile strength detection of the wiring harness. The current automobile wiring harness strength detection equipment is manually fixed at both ends and then tested. This method requires testing one by one, and after testing a wiring harness, it needs to be manually removed and the next group is placed. This method not only has poor continuity in the detection of multiple groups of wiring harnesses, but also has a low degree of automation, slow detection speed and low efficiency. Summary of the invention

[0012] In some embodiments, the magnetic ring is fixedly connected to the side end of the swing handle, the clamping toothed disc is movably connected to the upper end of the displacement test plate, and the limiting slider is fixedly connected to the bottom end of the displacement test plate.

[0013] In some of the embodiments, the outer side of the clamping toothed disc is provided with a tooth groove structure identical to the outer side of the linkage gear, and the other side is provided with an external protrusion structure larger in size than the tooth groove.

[0014] In some of the embodiments, the linkage gear, the swing handle and the clamping toothed disc are provided in two groups and rotate in opposite directions.

[0016] In some of the embodiments, eight groups of hanging plates are provided, and the hanging plates close to the side of the limit support frame are always on the same horizontal axis with it. An inner groove structure is opened in the middle of the end surface of the hanging plate close to the outer side, and the size of the inner groove structure is adjusted according to the size of the detected automobile wiring harness terminal.

[0017] Compared with the prior art, the present invention provides an automobile wiring harness detection device:

[0018] A vehicle wiring harness detection device is provided, by setting a displacement test plate, a limit support frame, a wheel test frame, a transmission screw rod, a ball sleeve and a clamping gear plate.

Compared with the current method of replacing the wiring harnesses after each test, it not only greatly improves the degree of automation and detection efficiency, but also reduces the workload of workers. Moreover, the quick and smooth completion of the detection of a batch of wiring harnesses can make the test data more accurate. BRIEF DESCRIPTION OF THE DRAWINGS
