Description

Technical Field

[0001] This utility model relates to the field of automotive testing technology, and in particular to an automotive wiring harness testing device. Background Technology

[0002] With the rapid development of intelligent and electric vehicles, the complexity and variety of automotive wiring harnesses are constantly increasing, which places higher demands on the accuracy, efficiency, and versatility of automotive wiring harness testing equipment. As a core tool for ensuring wiring harness quality, the performance of automotive wiring harness testing equipment directly affects the reliability of the vehicle's electrical system. Therefore, developing testing equipment that can quickly and accurately test different types of wiring harnesses and flexibly adapt to production needs has become an important research direction in the automotive manufacturing and parts production fields.

[0003] Existing automotive wiring harness testing equipment typically employs fixed fixtures to position and secure the wiring harnesses. The harnesses are placed at pre-set testing stations manually or using simple mechanical devices, and electrical performance testing is performed by contacting the wiring harness connectors with probes. These fixed fixtures are usually designed for specific wiring harness specifications and are incompatible with other types of harnesses. Furthermore, in terms of position adjustment, some equipment has fixed testing stations and lacks flexible adjustment mechanisms. When the size or shape of the wiring harness changes, it cannot be quickly adapted, requiring manual readjustment or tooling replacement, making the operation process cumbersome.

[0004] However, traditional automotive wiring harness testing equipment has significant shortcomings. Its fixed fixtures and non-adjustable testing stations make it difficult for the equipment to adapt to the testing needs of different specifications and types of wiring harnesses. When producing multiple models of wiring harnesses, it is necessary to frequently change fixtures and adjust testing stations, which consumes a lot of time and manpower. Inaccurate positioning will also affect the testing accuracy, greatly reducing the clamping efficiency and production flexibility of wiring harness testing. It cannot meet the efficient and diversified production needs of the modern automotive manufacturing industry. Therefore, an automotive wiring harness testing equipment is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automotive wiring harness testing device, which aims to improve the problems of poor adaptability of wiring harness fixing methods and cumbersome operation in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automotive wiring harness testing device includes a support platform with multiple sliding grooves inside the support platform, the sliding grooves being arranged in an array, a testing component being provided on one side of the top of the support platform, and a fixing component being provided inside each sliding groove.

[0008] The fixing component includes a sliding block, the outer wall of which is slidably connected to the inner wall of the slide groove. A rotating platform is fixedly connected to the top of the sliding block, and a fixing plate is rotatably connected to the top of the rotating platform. A fixing block is fixedly connected to the top of the fixing plate. Guide grooves are provided on both the upper and lower sides of the inner wall of the fixing block. Movable columns are slidably connected to both sides of the fixing block. A limit block is fixedly connected to one end of each movable column, and a sliding plate is fixedly connected to the other end of each movable column.

[0011] As a further description of the above technical solution:

[0012] A controller is provided on the top of the support platform, and the bottom of the controller is fixedly connected to the top of the support platform. The controller is located on the side of the slide.

[0013] As a further description of the above technical solution:

[0014] The bottom of the support platform is fixedly connected to multiple support legs, which are distributed in an array.

[0015] As a further description of the above technical solution:

[0016] Positioning holes are provided on both the left and right sides of the inner wall of the slide groove. The positioning holes are distributed in an array. The sliding block has symmetrical positioning posts on both sides inside. The outer wall of the positioning post is slidably connected to the inner wall of the positioning hole.

[0017] As a further description of the above technical solution:

[0018] A linkage plate is provided on the side of the positioning column. The linkage plate is located inside the sliding block, and the outer wall of the linkage plate is slidably connected to the inner wall of the sliding block.

[0019] As a further description of the above technical solution:

[0020] Each linkage plate has a linkage column fixedly connected to the upper side wall. The outer wall of the linkage column is slidably connected to the inside of the sliding block.

[0021] As a further description of the above technical solution:

[0022] Symmetrical limiting springs are provided between the side walls of the linkage plate, and both ends of the limiting springs are fixedly connected to the side walls of the linkage plate.

[0023] This utility model has the following beneficial effects:

[0024] 1.

Then, the wire harness is passed through multiple fixing blocks, and one end is inserted into the corresponding socket on the side wall of the testing platform. After the limiting blocks are released, the return spring pushes back to reset the sliding plate and clamping plate. The clamping plate holds and fixes the outer wall of the wire harness, thereby achieving the effect of quickly fixing different types of wire harnesses. This solves the problems of poor adaptability and cumbersome operation of traditional fixing methods, and improves the clamping efficiency and versatility of wire harness testing.

[0025] 2. In this utility model, the operator first confirms the position of the wire harness, then manually presses the buttons on both sides of the sliding block. This causes the linkage plate to slide inward via the linkage column, retracting the positioning column and compressing the limit spring. After the positioning column disengages from the positioning hole, the sliding block can be slid to a suitable position within the groove. Releasing the buttons causes the limit spring to push back, inserting the positioning column into the positioning hole, thus completing the adjustment of the sliding block's position. This achieves the effect of quickly adjusting and fixing the wire harness position, solving the problem of the inability to adjust the fixed position of traditional wire harnesses and improving the flexibility and efficiency of wire harness inspection.

It is used to control the testing process, display the testing results, and communicate with external devices. The bottom of the controller 7 is fixedly connected to the top of the support platform 1. The controller 7 is located on the side of the slide 3. Multiple support legs 2 are fixedly connected to the bottom of the support platform 1 by bolts. The support legs 2 are distributed in an array. The support legs 2 are welded from steel pipes and are used to support the entire equipment to ensure the stability of the equipment during use.

[0036] Reference Figure 4 and Figure 5The inner walls of the slide 3 are machined with positioning holes 4 on both sides. The positioning holes 4 are arranged in an array and are used to cooperate with the positioning posts 21 to lock the sliding block 8. The array layout of the positioning holes 4 can meet the diverse needs of fixing the position of the components during different wire harness testing. The sliding block 8 has symmetrical positioning post 21 mounting chambers on both sides inside by milling. Each chamber has a symmetrical positioning post 21 inside. The positioning posts 21 are made of alloy steel and are used to insert into the positioning holes 4 to fix the position of the sliding block 8. The outer wall of the positioning post 21 is slidably connected to the inner wall of the positioning hole 4. A linkage plate 20 is provided on the side of the positioning post 21. The linkage plate 20 is stamped from a 304 stainless steel sheet. The linkage plate 20 is located inside the sliding block 8, and its outer wall is slidably connected to the inner wall of the sliding block 8. The grooves in the wall form a sliding fit to transmit the displacement of button 18 and drive the positioning column 21 to move. Linkage columns 19 are fixedly connected to the upper side wall of linkage plate 20. Linkage columns 19 are used to transmit the displacement of button 18 to linkage plate 20. The outer wall of linkage column 19 is slidably connected to the inside of sliding block 8. Button 18 is fixedly connected to the side wall of linkage column 19. Button 18 is made of engineering plastic ABS with anti-slip texture on the surface. It is located outside of sliding block 8 for easy operation by the operator. Button 18 is located outside of sliding block 8. Symmetrical limit springs 22 are set between the side walls of linkage plate 20. Limit springs 22 are made of 65Mn spring steel. Both ends of limit springs 22 are fixedly connected to spring seats preset on the side wall of linkage plate 20 to provide reset elasticity for linkage plate 20 and realize the automatic locking and unlocking function of positioning column 21.

[0037] Working principle: Before using the automotive wiring harness testing equipment, the operator first confirms that the wire harness to be tested has passed through the fixing block. After releasing the limiting block 19, the linkage plate 20 slides inward. The sliding of the linkage plate 20 then causes the positioning post 21 to retract inward, and the limiting spring 22 is compressed. After the positioning post 21 is disengaged from the positioning hole 4, the operator can slide the sliding block 8 inside the slide groove 3. When the sliding block 8 is moved to the appropriate position, the operator can release the button 18. Under the counter-push of the limiting spring 22, the positioning post 21 is inserted back into the positioning hole 4, thus completing the adjustment of the position of the sliding block 8, thereby achieving the effect of quickly adjusting the position of the fixed wiring harness.

[0038] Then, the staff manually pulled the limiting blocks 14 located on both sides of the fixed block 11. The displacement of the limiting blocks 14 caused the movable column 13 to move as well, which in turn caused the sliding plate 16 and the clamping plate 17 to move outward, and the return spring 15 to be compressed. Then, the staff passed the wire harness through multiple fixed blocks 11 and inserted one end of the wire harness into the corresponding socket 6 on the side wall of the testing table 5. Then, the staff released the limiting blocks 14. Under the push of the return spring 15, the sliding plate 16 and the clamping plate 17 returned to their original positions. The clamping plate 17 clamped and fixed the outer wall of the wire harness, thereby achieving the effect of quickly fixing different types of wire harnesses.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
