Description

TECHNICAL FIELD

[0001] The application relates to the technical field of wire harness testing, in particular to an automobile wire harness torsion testing device. BACKGROUND

[0002] The automobile wire harness is a component for connecting circuits, which is formed by bundling a contact terminal (connector) and a wire cable pressed together, and then wrapping an insulator or a metal shell outside.

[0003] However, the automobile wire harness may be twisted and bent during vehicle use, at which time the automobile wire harness needs to be tested for torsion to evaluate whether the wire core breaks, the wire harness is damaged, the buckle falls off, the rubber sleeve falls off, and the like, so as to ensure the stability and safety of the wire harness in actual use.

[0004] For example, the patent with the publication number CN219417009U discloses a torsion testing device for automobile wire harness. The wire harness can be tensioned by the guide roller to keep the tensioned state, the torsion motor can control the torsion force by controlling the rotation angle, and the damage of the wire harness between the guide roller and the torsion wire harness chuck can be observed, which is intuitive and convenient, and the testing is more convenient and accurate.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0037] like Figures 1-3 As shown, this application provides an automotive wiring harness torsion testing device, including a housing 1 and a torsion mechanism 3 fixedly mounted on the upper end of the housing 1. The torsion mechanism 3 is used for torsion testing of the wiring harness. The torsion mechanism 3 includes multiple sets of support frames 31 fixedly mounted on the upper end of the housing 1. The upper end bearing of the support frame 31 is equipped with a support wheel (not shown in the figure), and a turntable 32 is rotatably mounted on the upper end of the support wheel. At the same time, a motor 34 is fixedly mounted on the bottom end of the housing 1. The output end of the motor 34 passes through the housing 1 and is fixedly connected to the turntable 32, so that the turntable 32 can be driven by the motor 34 to rotate under the guidance of the support wheel.

[0038] In order to fix one end of the wire harness, a fixing plate 33 is fixedly installed on the turntable 32. A first fixing part 35 is fixedly installed on one end of the fixing plate 33. The first fixing part 35 includes a base 40 fixedly installed on the fixing plate 33. The base 40 has a groove (not shown in the figure) and a frame 41 is fixedly installed on the base 40.

[0041] When the angle needs to be adjusted, the staff can manually push the installation plate 395 to slide along the guide groove 392 on the arc-shaped plate 391 until it moves to the appropriate position, and then fix it with the corresponding threaded hole through the positioning bolt 394, so that the wire harness changes from the vertical state to different angle inclination, and then the wire harness can be twisted at different angles;

[0042] After the angle adjustment is completed, one end of the wire harness can be fixed through the first fixing part 35, and after the wire harness passes through the gap between the two groups of buffer rollers 396, it is fixed through the second fixing part 397. After the fixing is completed, the motor 34 can be started to drive the rotating disc 32 to rotate, so that the wire harness is twisted under the limitation of the buffer rollers 396 while rotating, and then the effect of twisting test under the condition of changing the angle of the wire harness can be achieved to adapt to different driving environments;

[0043] As shown in Figure 4 and Figure 6 In order to smoothly perform the twisting test, a stabilizing part 9 is arranged at the top end of the support 30, which is used for further fixing the wire harness. The stabilizing part 9 includes a stabilizing plate 90 fixed at the top end of the support 30, one end of the stabilizing plate 90 is fixed with a block 91, and the end away from the block 91 is fixed with a fixing frame 92, the fixing frame 92 is threadedly connected with a bolt 93, and one end of the bolt 93 is fixed with a hand wheel 95, so as to rotate the bolt 93;
