Description

Technical Field

[0001] The utility model relates to the field of wire harness detection, in particular to a detection fixture for an automotive wire harness. Background Art

[0002] A wire harness is the overall equipment that provides services for a certain load source group, such as relay lines, switching devices, control systems, etc. The basic research content of traffic theory is to study the relationship among traffic volume, call loss, and wire harness capacity. Therefore, a wire harness is an important basic concept in traffic theory, and different detection devices need to be used to detect it before the wire harness is installed to ensure its normal use.

[0003] For example, the patent document with the publication number CN220583940U discloses a detection fixture for an automotive wire harness. By rotating the screw rods at both ends and under the action of the limiting rod and the slider, the fixing plate can move vertically in the direction of the screw rod. At this time, the detector will adjust the rotation speed of the motor according to the tensile force value borne by the wire harness, so that the screw rod rotates slowly. When the wire harness reaches the standard tensile force required for production, the receiver will receive the data transmitted by the detector. However, the detection of tensile force by this device has a large limitation on the total length of the wire harness. Content of the Utility Model

[0004] The purpose of the utility model is to provide a detection fixture for an automotive wire harness to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions:

[0006] A detection fixture for an automotive wire harness includes an equipment platform. The upper surface of the equipment platform is provided with winding mechanisms symmetrically distributed left and right. The winding mechanism includes two barrels. One end of the barrels close to each other is provided with an opening. The other end of the barrels far from each other is fixedly connected with a first electric telescopic rod. The other end of the first electric telescopic rod far from each other is fixedly connected with a cylinder. The middle of the cylinder is rotationally connected with a vertical plate. The bottom end of the vertical plate is fixedly connected with the equipment platform. The cylinder is slidably connected with sliding columns distributed in a circumferential array. One end of the sliding column is fixedly connected with the barrel. A clamping mechanism is arranged inside the barrel, and a synchronization mechanism is arranged on the vertical plate.

[0007] Preferably, one end of the barrels close to each other is provided with a notch for the wire harness to extend out.

[0008] Preferably, the clamping mechanism includes a groove body. The groove body is arranged along the axial direction of the barrel. The groove body is opened inside the barrel. The barrel is slidably connected with a clamping plate. One side of the clamping plate far from each other is fixedly connected with a second electric telescopic rod. The second electric telescopic rod is fixedly connected with the barrel.

[0009] Preferably, the synchronization mechanism includes two synchronization shafts, which are arranged on the side far away from each other of the winding mechanism. The synchronization shafts are rotatably connected with bearing seats, and the bearing seats are fixedly connected with vertical plates. Gear two is fixedly connected to both ends of the synchronization shaft, and gear two meshes with gear one. Gear one is fixedly connected with a cylinder, and a power component is arranged on one of the vertical plates.

[0010] Preferably, the power component includes two motors, which are installed on the rear vertical plate. The output shaft of the motor is fixedly connected with a driving gear, and the driving gear meshes with gear one.

[0011] Preferably, an outer shell is arranged outside the winding mechanism. One side of the outer shell is hinged with an equipment platform, and an observation window is arranged on the other side of the outer shell.

[0012] The beneficial effects are as follows: Clamp the end of the wire harness inside the barrel body, combine the barrel bodies, lead out the wire harness from the gap, and wind both ends of the wire harness outside the vertical plate as the barrel body rotates. As the winding at both ends increases, the wire harness is tightened, and the tensile strength of a longer wire harness can be detected.

The bottom end of the vertical plate 201 is fixedly connected to the equipment platform 100. The cylinder 202 is slidably connected to slide columns 205 distributed in a circumferential array. One end of the slide columns 205 is fixedly connected to the barrel bodies 204. A clamping mechanism is provided inside the barrel bodies 204, and a synchronous mechanism is provided on the vertical plate 201.

[0025] The vertical plate 201 is used to rotatably connect the cylinder 202. The cylinder 202 is slidably connected to the slide columns 205 and fixedly connected to the electric telescopic rod 1 203. The electric telescopic rod 1 203 is used to push the barrel bodies 204 closer to each other. The two barrel bodies 204 form a cylinder for winding the wire harness. The slide columns 205 are used to keep the barrel bodies 204 and the slide columns 205 rotating synchronously.

[0026] One end of the barrel bodies 204 close to each other is provided with a notch 206 for the wire harness to extend out.

[0027] Put the end of the wire harness into the barrel body 204 and pass it out through the notch 206 to facilitate the winding of the wire harness.

[0028] The clamping mechanism includes a groove body 302. The groove body 302 is arranged along the axial direction of the barrel body 204. The groove body 302 is opened inside the barrel body 204. A clamping plate 303 is slidably connected to the barrel body 204. On the mutually remote sides of the clamping plates 303, there are fixedly connected electric telescopic rods two 301, and the electric telescopic rods two 301 are fixedly connected to the barrel body 204.

[0029] The electric telescopic rod two 301 pushes the clamping plate 303 to clamp the end of the wire harness, and the groove body 302 is used for slidably connecting the clamping plate 303.

[0030] The synchronization mechanism includes two synchronization shafts 403. The synchronization shafts 403 are arranged on the mutually remote sides of the winding mechanism. The synchronization shafts 403 are rotatably connected to bearing seats 404, and the bearing seats 404 are fixedly connected to the vertical plates 201. At both ends of the synchronization shafts 403, there are fixedly connected gears two 402.

At this time, start the second electric telescopic rod 301. The second electric telescopic rod 301 pushes the clamping plate 303 so that the clamping plate 303 clamps the end of the wire harness. Start the motor 405 to drive the driving gear 406 to rotate, thereby driving the first gear 401 and the cylinder 202 on the same side to rotate, and at the same time driving the second gear 402 and the synchronous shaft 403 to rotate, so that the first gear 401 and the cylinder 202 on the other side rotate synchronously. Driven by the sliding column 205, the barrel body 204 rotates synchronously to wind the wire harness, and then tighten the wire harness to facilitate the detection of the tensile performance of the wire harness.
