Description

Technical Field

[0001] The utility model relates to the technical field of wire harness testing, in particular to an automobile wire harness testing device. Background Art

[0002] The automotive wiring harness is the main network component of the vehicle circuit. After production, the performance of the automotive wiring harness needs to be tested to ensure that the quality of the automotive wiring harness is up to standard. The car door is a key moving part of the car body and plays an important role in protecting the safety of the occupants. Therefore, the bending durability of the automotive door wiring harness is crucial.

[0003] During the bending durability test of the wiring harness, the wiring harness to be tested needs to be bent and straightened repeatedly. After a section of the wiring harness to be tested has been bent back and forth a predetermined number of times, the wiring harness to be tested is removed for a power-on test. If the power-on test is qualified, it means that the bending resistance performance of the wiring harness is qualified.

[0004] In existing bending durability tests for wiring harnesses, the bending direction of the arc-shaped bending section is always consistent. This consistent bending form enables the wiring harness to produce an adaptive effect in the durability test. However, in actual use of the wiring harness, the bending direction of the wiring harness is not constant. The wiring harness itself will twist during the bending process, making the durability test results better than actual use. Utility Model Content

[0028] Please refer to Figure 1-7 A vehicle wiring harness testing device includes a base plate 1, a driving mechanism 2 arranged at the top of the base plate 1, a clamping part 3 arranged on the driving mechanism 2, a clamping part 4 arranged on one side of the driving mechanism 2, and a limiter 5 arranged at the top of the base plate 1. The clamping part 3 and the clamping part 4 are respectively used to clamp the upper and lower ends of the wiring harness 6 to be tested. The clamping part 24 clamps one end of the wiring harness 6, and the clamping part 3 clamps the other end of the wiring harness 6. The driving mechanism 2 drives the clamping part 3 to make the other end of the wiring harness 6 swing left and right on the limiter 5.

[0029] Specifically, the drive mechanism 2 includes a motor 21, a rotating column 22 disposed at the output end of the motor 21, a rotating cylinder 23 rotatably disposed on the outer circumference of the rotating column 22, and a housing 24 disposed at the top of the base plate 1. The rotating cylinder 23 and the rotating column 22 are both rotatably disposed within the housing 24. A support block 11 is disposed at the top of the base plate 1, the motor 21 is disposed on the support block 11, and the rotating cylinder 23 is an annular cylinder.

[0030] A groove 221 is provided on the outer surface of the rotating column 22, and the groove 221 includes an annular groove 1 2211, an annular groove 2 2212, a spiral groove 1 2213 and a spiral groove 2 2214. The annular groove 1 2211, the spiral groove 1 2213, the annular groove 2 2212 and the spiral groove 2 2214 are connected end to end to form a closed groove path. The annular groove 1 2211 and the annular groove 2 2212 are arranged in reverse at opposite ends of the rotating column 22, and the spiral groove 1 2213 and the spiral groove 2 2214 are arranged symmetrically.

[0031] The rotating cylinder 23 is provided with a sliding groove 231 extending along the axial direction of the rotating cylinder 23. A slider 232 is slidably disposed within the sliding groove 231. The slider 232 is provided with a pin 2321, which is slidably connected to the groove 221. The pin 2321 is restrained by the groove 221, so that rotation of the groove 221 can drive the pin 2321 to move. The pin 2321 drives the slider 232 to move. The slider 232 drives the rotating cylinder 23 to move via the sliding groove 231.

[0032] like Figure 4 When the rotating column 22 rotates clockwise, the groove 221 rotates clockwise and drives the pin shaft 2321 to pass through the annular groove 1 2211, the spiral groove 2 2214, the annular groove 2212 and the spiral groove 1 2213 in sequence, and then return to the annular groove 1 2211, so that the pin shaft 2321 reciprocates back and forth.

[0033] The motor 21 is started to drive the rotating column 22 to rotate. The rotation of the rotating column 22 drives the pin 2321 to reciprocate in the groove 221. The pin 2321 cooperates with the slider 232 to drive the rotating cylinder 23 to rotate left and right.

[0034] A rocker arm 7 is provided on the side of the rotating cylinder 23 extending out of the housing 24 away from the motor 21, a cross bar 71 is provided on the rocker arm 7, a support plate 72 is provided on the side of the rocker arm 7 close to the clamping part 2 4, and a through hole is provided on the support plate 72 so that the wiring harness 6 can pass through the support plate 72 through the through hole.

[0035] The clamping portion 3 includes a rotating ring 31 rotatably mounted on the top of the support plate 72, a gear ring 32 mounted on the top of the rotating ring 31, and a clamping block 33 movably mounted on the gear ring 32. The upper end of the wire harness 6 passes through the through hole of the support plate 72, the center of the rotating ring 31, and the center of the gear ring 32 in sequence, and is then clamped by the clamping block 33.

[0036] The limiting member 5 is in the shape of a semicircular ring, and the two ends of the semicircular ring are arranged at the top of the base plate 1. A sliding groove 51 is provided at the top of the limiting member 5. The sliding groove 51 is semicircular. The rocker arm 7 is slidably set in the sliding groove 51. A tooth segment 52 is provided on the outer surface of one side of the limiting member 5 close to the gear ring 32. The tooth segment 52 is provided with four sections, and there is a gap between the four sections of the tooth segment 52.

[0037] A rack 73 is slidingly provided on one side of the cross bar 71 close to the gear ring 32, and a tooth 1 731 is provided at the bottom end of the rack 73. A gear 74 is provided below the rack 73, and the gear 74 is rotatably connected to the rocker 7. The gear 74 meshes with the tooth 1 731, and the gear 74 can mesh with the tooth segment 52.

[0038] A second tooth 732 is provided on a side of the rack 73 close to the gear ring 32 , and the second tooth 732 is meshed with the gear ring 32 .

[0039] The second clamping portion 4 includes a support frame 41, a screw rod 42, and a second clamping block 43. The support frame 41 is arranged at the top of the base plate 1, the screw rod 42 is rotatably arranged on the support frame 41, and the clamping block is arranged at one end of the screw rod 42. The rotation of the screw rod 42 drives the second clamping block 43 to fix the lower end of the wire harness 6.

[0040] When the motor 21 drives the swing arm 7 to swing back and forth, it drives the clamping portion 1 3 to swing left and right. When the gear 74 meshes with the tooth segment 52, the tooth segment 52 drives the gear 74 to rotate. The rotation of the gear 74 causes the meshing tooth 1 731 and the rack 73 to slide on the crossbar 71. The sliding of the rack 73 causes the tooth 2 732 to rotate the gear ring 32. The rotation of the gear ring 32 rotates the clamping block 1 33, which in turn twists the upper end of the wiring harness 6. When the gear 74 passes through the gap between the tooth segments 52, the twisted wiring harness 6 drives the clamping block 1 33 and the gear ring 32 to rotate in the opposite direction. The reversely rotating gear ring 32 drives the rack 73 to slide back to the center of the crossbar 71. When the rocker arm 7 swings back and forth on the left and right sides of the limit member 5, driven by the tooth segment 52, the gear ring 32 drives the upper end of the wiring harness 6 to repeatedly twist and recover, so that the bending durability test of the wiring harness 6 is closer to the actual usage situation and the test result is more accurate.
