Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The device for detecting the air tightness of the automobile wire harness comprises a base 1, wherein a sliding rail 2 is arranged on the upper end face of the base 1, an air inlet wire harness connector 3 is fixed at one end of the sliding rail 2, the position of the air inlet wire harness connector 3 is adjustable, and the air inlet wire harness connector 3 is fixed on the sliding rail 2 after being adjusted. The other end of the slide rail 2 is provided with an air outlet wire harness joint 4 in a sliding manner. The air inlet end of the air inlet wire harness joint 3 is sequentially connected with an air inlet gas flowmeter 5 and an air pump 6 in series, and the air outlet end of the air outlet wire harness joint 4 is connected with an air outlet gas flowmeter 7; and the two ends of the automobile wire harness are respectively connected with the air inlet wire harness joint 3 and the air outlet wire harness joint 4.
The air outlet harness joint 4 comprises a sliding seat 8, an upper joint part 9 and a motor 10, and the lower end face of the sliding seat 8 is in sliding fit with the sliding rail 2; a sliding seat sliding rail 11 is arranged on the upper end surface of the sliding seat 8, and the upper joint part 9 is in sliding fit with the sliding seat sliding rail 11 and is driven by the motor 10 to slide; the track extending direction of the slide rail 11 is the same as the track extending direction of the slide rail 2.
A side plate 19 extends downwards from one side of the sliding seat 8, a bolt hole 20 is formed in the side plate 19, and a fastening bolt 21 penetrates through the bolt hole 20 and is pressed against one side of the sliding rail 2 to fix the air outlet wire harness joint 4.
When the gas tightness of carrying out the car pencil can be examined, connect the automobile skilled both ends respectively on the pencil joint 3 that admits air connects 4 with the pencil of giving vent to anger, the pencil that admits air at this moment connects 3 to fix on slide rail 2. An operator manually adjusts the position of the air outlet wire harness connector 4 on the sliding rail 2, so that the automobile wire harness is in a straightened state when being observed by naked eyes. And then the air outlet harness joint 4 is fixed with the slide rail 2 by using a fastening bolt 21. After that, the motor 10 is turned on, and the motor 10 drives the upper joint part 9 to move towards the side far away from the air inlet wire harness joint 3 along the slide seat slide rail 11, so as to further straighten the automobile wire harness.
Because the car pencil differs, if direct installation motor on the pencil joint 4 of giving vent to anger, then do not confirm the initial position that the pencil joint 4 of giving vent to anger well, the power size of motor also is difficult to hold between fingers, and too big excessive straightening of power leads to the car pencil to receive the damage easily, and the too small power then causes the moving speed slow easily, and the adjustment is with straightening time partially long. The first straightening of the utility model is manually adjusted straightening, and the speed is faster; and a motor with lower power is adopted for the second time, so that secondary straightening adjustment can be quickly completed under the condition that the automobile wire harness is not damaged.
The sliding rail 2 is provided with a support bracket 12 in a sliding manner, and the support bracket 12 is used for assisting in supporting the automobile wiring harness.

One end of the slide rail 2, which is close to the air inlet wire harness joint 3, is provided with a differential gear set 14, the differential gear set 14 comprises two gears which are coaxially arranged, a rotating shaft 15 of the differential gear set is vertically arranged, and the radius of the large gear 16 is twice of that of the small gear 22. A large rack 17 is fixedly connected below the air outlet wire harness joint 4, and the large rack 17 is in transmission fit with the large gear 16; a small rack 18 is fixedly connected below the supporting bracket 12, and the small rack 18 is in transmission fit with the pinion 22; the length direction of the large rack 17 and the small rack 18 is along the extending direction of the slide rail 2, and the large rack 17 and the small rack 18 are located on the same side of the differential gear set 14.
When an operator manually adjusts the position of the air outlet wire harness connector 4 on the sliding rail 2, the air outlet wire harness connector 4 drives the large gear 16 to rotate through the large rack 17, the large gear 16 drives the coaxially arranged small gear 22 to rotate, and the small gear 22 drives the supporting bracket 12 to move through the small rack 18. The large rack 17 and the small rack 18 are positioned on the same side of the differential gear set 14, so that the movement directions of the support bracket 12 and the air outlet harness joint 4 on the slide rail are consistent. The radius of the large gear 16 is twice that of the small gear 22, so that when the support bracket 12 is in the middle position of the air inlet harness joint 3 and the air outlet harness joint 4 in the initial state, the support bracket 12 can be consistently kept in the middle position of the air inlet harness joint 3 and the air outlet harness joint 4 in the subsequent movement process of the air outlet harness joint 4, and the support effect of the support bracket 12 is better.
The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
