Description

Technical Field

[0001] This utility model relates to the field of wire harness testing technology, specifically a testing platform for wire harness quality testing. Background Technology

[0002] Pipes and wire harnesses are used for the transmission of hydraulic media and electrical signals. In practical applications, pipes often need to be arranged according to the layout of the scene. When passing through some sharp or small angle positions, the bending radius of the pipes may be too small, affecting its transmission performance, or even causing the pipes to break or break. Therefore, wire harnesses need to be quality inspected during the processing and production process.

[0003] Currently available wire harness quality testing platforms on the market offer relatively limited testing methods. These platforms can only perform one specific test on the wire harness. For example, after testing the wire harness's tensile strength, if a bending test is required, another independent test must be conducted. In such cases, to complete comprehensive quality testing, different testing equipment needs to be constantly replaced, leading to a decrease in quality testing efficiency.

[0004] Therefore, those skilled in the art have provided a testing platform for wire harness quality inspection to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a testing platform for wire harness quality inspection, so as to solve the problem mentioned in the background art that the existing wire harness inspection cannot simultaneously meet the requirements of bending and tensile strength testing.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A testing platform for wire harness quality inspection includes: a testing table, a back plate fixedly mounted on the surface of the testing table, a rotating cylinder rotatably mounted on the front side of the back plate, a second umbrella wheel fixedly mounted on the upper end of the rotating cylinder, a winding column fixedly mounted on the right side of the rotating cylinder, a drive gear rotatably mounted on the surface of the back plate, a first gear disposed above the drive gear, a first umbrella wheel fixedly mounted on the front wall of the first gear, a winding roller mounted on the rear wall of the back plate, and a drive motor connected to the center line of the rear wall of the first gear.

[0008] As a further embodiment of this utility model: the winding roller and the drive gear are interconnected, and the drive gear and the first gear are meshed.

[0009] As a further improvement of this utility model: the first gear is fixedly connected to the first parasol wheel, and the first parasol wheel and the second parasol wheel are meshing.

[0010] As a further embodiment of this utility model: the second umbrella wheel is fixedly connected to the rotating cylinder, and a rotating seat is rotatably mounted on the lower end of the rotating cylinder. The bottom of the rotating seat is fixedly mounted to the testing platform, and the rotating cylinder and the rotating seat are a rotating structure.

[0011] As a further embodiment of this utility model: a fixing rod is fixedly provided on the front side of the surface of the surrounding column, and a bracket is fixedly provided on the rear side of the surface of the surrounding column.

[0012] As a further improvement of this utility model, the height of the fixing rod is lower than the height of the bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The testing platform incorporates a rotating drum, winding roller, and winding column mounting structure. A wire harness is wound on the rotating drum, extending from the drum to the winding column. On the winding column, the wire harness is carefully wound multiple times before continuing to the winding roller. To achieve the movement of the wire harness, a drive motor is configured to drive a first gear, causing it to rotate. A meshing structure is used between the first gear and the drive gear to ensure synchronous movement between them. Furthermore, the first gear is fixedly connected to parasol wheel one, and a meshing structure is also used between parasol wheel one and parasol wheel two. This ensures synchronous rotation between parasol wheel one and parasol wheel two. When the first gear rotates, it not only drives the drive gear to rotate but also drives parasol wheel one to rotate. The rotation of parasol wheel one further drives parasol wheel two to rotate. The drive gear is responsible for driving the winding roller to rotate, while parasol wheel two... This mechanism drives the rotating drum. Notably, the clockwise rotation of parasol wheel one and the first gear causes the winding roller to rotate counterclockwise. Simultaneously, the clockwise rotation of parasol wheel one also causes the horizontally placed parasol wheel two to rotate counterclockwise. The counterclockwise rotation of parasol wheel two then drives the rotating drum to rotate counterclockwise. Through this design, the counterclockwise rotation of the rotating drum and the counterclockwise rotation of the winding roller work together to pull the wire harness, thereby achieving the toughness and tensile strength test of the wire harness. At the same time, as the wire harness is wound on the winding post, it will continuously tighten as the wire harness is pulled, which further performs the bending test of the wire harness wound on the winding post. Through this comprehensive detection mechanism, not only is the toughness and tensile strength test of the wire harness achieved, but the bending test of the wire harness is also completed, greatly improving the efficiency and accuracy of the test.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This utility model provides a testing platform for wire harness quality testing, including: a testing table 1, a back plate 2 fixedly installed on the surface of the testing table 1, a rotating cylinder 3 rotatably installed on the front side of the back plate 2, a second umbrella wheel 8 fixedly installed on the upper end of the rotating cylinder 3, a winding column 4 fixedly installed on the right side of the rotating cylinder 3, a drive gear 5 rotatably installed on the surface of the back plate 2, a first gear 6 arranged above the drive gear 5, a first umbrella wheel 7 fixedly installed on the front wall of the first gear 6, a winding roller 10 installed on the rear wall of the back plate 2, a fixing rod 13 fixedly arranged on the front side of the surface of the winding column 4, and a bracket 14 fixedly arranged on the rear side of the surface of the winding column 4, the height of the fixing rod 13 being lower than the height of the bracket 14;

[0022] Specifically, the wire harness 11 is wound around the rotating cylinder 3 and extends to the winding post 4. The fixing rod 13 presses down on the wire harness 11, pressing one end of the wire harness 11 to the lower end of the winding post 4. The wire harness 11 is wound around the winding post 4 multiple times. The bracket 14 supports the extended end of the wire harness 11 at the upper end of the winding post 4, so that the wire harness 11 is wound around the winding post 4. The two ends of the wire harness 11 are respectively connected to the winding roller 10 and the rotating cylinder 3. While the winding roller 10 and the rotating cylinder 3 rotate and pull the wire harness 11, the wire harness 11 on the winding post 4 will also tighten continuously as the wire harness 11 is pulled. This further performs bending detection on the wire harness 11 wound on the winding post 4. Through this comprehensive detection mechanism, not only is the toughness and tensile strength of the wire harness 11 tested, but also the bending of the wire harness 11 is tested.

[0023] The rear wall centerline of the first gear 6 is connected to the drive motor 9. The winding roller 10 is connected to the drive gear 5. The drive gear 5 and the first gear 6 are meshed. The first gear 6 is fixedly connected to the parasol wheel 7. The parasol wheel 7 and the parasol wheel 8 are meshed. The parasol wheel 8 is fixedly connected to the rotating cylinder 3. The lower end of the rotating cylinder 3 is rotatably mounted with a rotating seat 12. The bottom of the rotating seat 12 is fixedly mounted to the detection table 1. The rotating cylinder 3 and the rotating seat 12 are rotatable.

[0024] Specifically, the winding roller 10 and the drive gear 5 are connected by a fixed connection, ensuring their stability and synchronization. The drive gear 5 and the back plate 2 are designed with a rotating structure, allowing the drive gear 5 to rotate freely on the back plate 2. This design enables the winding roller 10 to rotate with the drive gear 5, thus achieving its function. The drive motor 9 is the core power source of the entire system. It is responsible for driving the first gear 6 and the parasol wheel 7 fixedly connected to the first gear 6 to rotate. The first gear 6, through its unique meshing structure, can effectively drive the drive gear 5 to rotate. At the same time, the rotation of the parasol wheel 7 will drive the parasol wheel 8 to rotate, and the parasol wheel 8 is responsible for driving the rotating cylinder 3 to rotate. In this series of transmission processes, the first gear... Wheel 6, drive gear 5, and parasol wheel 7 are arranged vertically from front to back, while parasol wheel 8 is arranged horizontally from top to bottom. This layout design allows the vertically arranged first gear 6 to drive the drive gear 5 below to rotate counterclockwise when it rotates clockwise. The winding roller 10 will also rotate counterclockwise with the drive gear 5. The clockwise rotation of parasol wheel 7 will drive the horizontally placed parasol wheel 8 to rotate counterclockwise. Through this ingenious transmission mechanism, the rotating drum 3 can effectively wind up the wire harness 11, while the winding roller 10 winds up the other end of the wire harness 11, ensuring the smoothness and efficiency of the entire winding process. In this way, the winding roller 10 and the rotating drum 3 pull the two ends of the wire harness 11 respectively, and the wire harness 11 is tested for toughness and tensile strength.

[0025] The working principle of this utility model is as follows:

[0026] When using this invention, firstly, start the drive motor 9. The drive motor 9 drives the first gear 6 and the parasol wheel 7 fixedly connected to the first gear 6 to rotate. The rotation of the parasol wheel 7 drives the parasol wheel 8 meshing with it to rotate. The rotation of the parasol wheel 8 drives the rotating cylinder 3 fixedly connected to it to rotate. At the same time, the first gear 6 drives the drive gear 5 to rotate through its meshing structure. The rotation of the drive gear 5 drives the winding roller 10 fixedly connected to it to rotate. At this time, one end of the wire harness 11 to be tested is fixed to the winding roller 10, and the other end is wound around the winding post 4 of the rotating cylinder 3. With the fixing rod 13 and bracket 14 working together to fix it, as the drive motor 9 continues to rotate, the winding roller 10 and the rotating cylinder 3 begin to pull the two ends of the wire harness 11 to wind it up. During this process, the wire harness 11 is continuously tightened on the winding column 4, completing the bending detection of the wire harness 11. At the same time, the rotation and pulling of the winding roller 10 and the rotating cylinder 3 also realizes the toughness and tensile strength detection of the wire harness 11. The entire detection process is highly automated, and through the transmission mechanism between the first gear 6, the drive gear 5, and the first parapet wheel 7 and the second parapet wheel 8, the comprehensive detection of the wire harness 11 is realized, which greatly improves the detection efficiency and accuracy.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
