Description

Technical Field

[0001] This utility model relates to the field of mechanical performance testing technology, specifically a novel mechanical performance testing device. Background Technology

[0002] After production, wire harnesses need to be sampled and tested using a wire harness tensile testing device to determine their mechanical properties and whether they meet national standards. Since the tensile strength of some wire harnesses directly affects the safety of users, the tensile mechanical properties test of wire harnesses is very important.

[0003] The prior art, disclosed in CN222232212U, provides a wire harness tensile testing device, including a base plate. Two fixed blocks are fixedly connected to the top of the base plate, and a movable block is slidably connected between the two fixed blocks. A cylinder is fixedly mounted on the top of the base plate, with one end of the cylinder's movable rod fixedly connected to one side of the movable block. A mounting plate is fixedly connected to the top of the movable block, and two second vertical plates are fixedly connected to the top of the mounting plate. This invention addresses the problem that traditional wire harness tensile testing devices can only perform tensile tests in a single direction. This fails to comprehensively assess the wire harness's capacity in different directions and may overlook potential problems in other directions. Furthermore, in reality, wire harnesses typically bear forces from different directions simultaneously, and traditional single-direction tensile tests cannot simulate these complex working conditions, leading to significant discrepancies between test results and actual usage.

[0004] The aforementioned patent mainly involves making the components that fix the wire harness movable, thereby conducting synchronous tests on the tensile force of the wire harness in different directions. However, this method of conducting tensile tests on the wire harness cannot rotate the wire harness, which often rotates due to external forces during use. This makes it impossible for the tensile testing device to comprehensively simulate the tensile force of the wire harness under actual use, greatly reducing the practicality of the tensile testing device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a new type of mechanical performance testing device, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A novel mechanical performance testing device includes a device body. A clamping and rotating assembly for holding and rotating a wire harness is fixedly mounted on one side of the device body. A push-pull assembly for pulling the wire harness and adjusting the force angle of the wire harness is movably mounted on the side of the device body away from the clamping and rotating assembly. The push-pull assembly includes a tension sensor for mechanical tensile testing. The device body includes a mounting frame. The clamping and rotating assembly includes a limiting frame fixed to the mounting frame. A third motor is fixedly mounted on the limiting frame. A shaft is fixedly connected to the output end of the third motor. A second clamping assembly for holding the wire harness is fixedly connected to the end of the shaft away from the third motor. This fixed connection allows the novel mechanical performance testing device to more securely fix both ends of the wire harness while performing subsequent operations, greatly improving the practicality of the novel mechanical performance testing device.

[0007] Furthermore, the second clamping assembly includes a housing fixed to the shaft. A winding shaft for winding is fixedly installed at the end of the housing away from the shaft. A rectangular groove for placing the wire harness is formed inside the housing. A threaded rod is movably connected to the housing within the rectangular groove. A turntable for facilitating rotation of the threaded rod is fixedly connected to the top of the threaded rod. A pressing plate for pressing the wire harness is fixedly connected to the end of the threaded rod away from the turntable. The pressing plate at the end of the threaded rod away from the turntable firmly fixes the wire harness to the bottom of the pressing plate, improving the stability of the new mechanical performance testing device in securing the wire harness.

[0008] Furthermore, slide rails are fixedly installed on both sides of the top of the mounting frame, and the push-pull assembly includes a movable plate that moves on the slide rails. Slide grooves are provided on both sides of the bottom of the movable plate. The slide grooves are adapted to the slide rails, so that the movable plate can move smoothly and limit its movement on the slide rails, thereby improving the smoothness of the operation of the internal structure of the new mechanical performance testing device.

[0009] Furthermore, a mounting frame is fixedly installed on the top side of the mounting bracket away from the clamping and rotating assembly, and a support plate is also fixedly installed on the top of the mounting bracket. The push-pull assembly includes a first motor fixed inside the mounting frame, and a lead screw is fixedly connected to the output end of the first motor. The lead screw is threadedly connected to the movable plate, and the end of the lead screw away from the first motor is rotatably located inside the support plate.

[0010] Furthermore, an adjustment component for adjusting the force angle of the wire harness is fixedly installed on the movable plate. A first clamping component for holding the wire harness is fixedly installed on one side of the adjustment component, and the tension sensor is located inside the first clamping component. The location of the tension sensor inside the first clamping component allows the tension sensor to directly test the tension of the wire harness when the first clamping component moves, improving the convenience of the new mechanical performance testing device for tensile testing.

[0011] Furthermore, the adjustment assembly includes a plate body fixedly mounted on a movable plate. A second motor and a controller are fixedly mounted on the top of the plate body. The control box of the second motor is electrically connected to the controller. A rotating shaft is fixedly connected to the output end of the second motor. An electric push rod is fixedly connected to the middle of the rotating shaft. The end of the electric push rod away from the rotating shaft is fixedly connected to the first clamping assembly. This fixed connection allows the electric push rod to directly adjust the position of the first clamping assembly, improving the integrated movement of the internal structure of the novel mechanical performance testing device.

[0012] Furthermore, the pressing plate is made of nylon. The nylon material significantly increases the friction between the pressing plate and the wire harness, allowing the wire harness to be firmly fixed to the bottom of the pressing plate, thus improving the practicality of the new mechanical performance testing device. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a motor and an electric actuator to control the swinging and extension of the clamping assembly that fixes the wire harness, and another motor to rotate another clamping assembly that fixes the wire harness. This allows the new mechanical performance testing device to perform tensile tests on the wire harness from multiple angles and rotations, greatly improving the versatility of the new mechanical performance testing device for wire harness tensile testing.

[0017] Example The following is in conjunction with the appendix Figure 1 - Appendix Figure 6This application provides a further detailed description. A novel mechanical performance testing device includes a device body 1. A clamping and rotating assembly 2 for clamping and rotating a wire harness is fixedly mounted on one side of the device body 1. A push-pull assembly 3 for pulling the wire harness and adjusting the force angle of the wire harness is movably mounted on the side of the device body 1 away from the clamping and rotating assembly 2. The push-pull assembly 3 includes a tension sensor 37 for mechanical tensile testing. The device body 1 includes a mounting frame 11. The clamping and rotating assembly 2 includes a limiting frame 21 fixed on the mounting frame 11. A third motor 22 is fixedly mounted on the limiting frame 21. A shaft 23 is fixedly connected to the output end of the third motor 22. The end of the shaft 23 away from the third motor 22 is fixed... A second clamping assembly 24 for clamping wire harnesses is connected. The second clamping assembly 24 includes a housing 243 fixed to the shaft 23. A winding shaft 241 for winding wire is fixedly installed at the end of the housing 243 away from the shaft 23. A rectangular groove for placing the wire harness is opened inside the housing 243. A threaded rod 246 is movably connected to the housing 243 within the rectangular groove. A turntable 245 for facilitating rotation of the threaded rod 246 is fixedly connected to the top of the threaded rod 246. A pressing plate 244 for pressing the wire harness is fixedly connected to the end of the threaded rod 246 away from the turntable 245. Slide rails 13 are fixedly installed on both sides of the top of the mounting bracket 11. Push-pull assembly 3 The assembly includes a movable plate 32 that moves on the slide rail 13. The movable plate 32 has grooves 33 on both sides of its bottom, which are adapted to the slide rail 13. A mounting frame 14 is fixedly mounted on the top of the mounting bracket 11 on the side away from the clamping assembly 2. A support plate 12 is also fixedly mounted on the top of the mounting bracket 11. The push-pull assembly 3 includes a first motor 35 fixed within the mounting frame 14. A lead screw 34 is fixedly connected to the output end of the first motor 35. The lead screw 34 is threadedly connected to the movable plate 32. The end of the lead screw 34 away from the first motor 35 rotates within the support plate 12. An adjustment assembly 36 for adjusting the force angle of the wire harness is fixedly mounted on the movable plate 32. The adjustment component 36 has a first clamping component 31 for clamping the wire harness fixedly installed on one side. The tension sensor 37 is located inside the first clamping component 31. The adjustment component 36 includes a plate 365 fixedly installed on the movable plate 32. A second motor 361 and a controller 362 are fixedly installed on the top of the plate 365. The control box of the second motor 361 is electrically connected to the controller 362. The output end of the second motor 361 is fixedly connected to a rotating shaft 364. An electric push rod 366 is fixedly connected in the middle of the rotating shaft 364. The end of the electric push rod 366 away from the rotating shaft 364 is fixedly connected to the first clamping component 31. The pressing plate 244 is made of nylon.

[0018] When fixing the wire harness, it is necessary to first wrap it around the shaft 241 several times, and then insert the end of the wire harness into the rectangular groove 242 and place it below the pressing plate 244. The user only needs to rotate the turntable 245 to allow the threaded rod 246 to move on the outer shell 243 and firmly fix the wire harness below the pressing plate 244.

[0019] Since the second clamping component 24 is directly fixed to the shaft 23 of the third motor 22, when the third motor 22 is running, the rotating shaft 23 can directly rotate the second clamping component 24, thereby allowing the wire harness to simulate real rotation.

[0020] Since the first clamping assembly 31, the electric push rod 366, and the second motor 361 are fixedly connected, the first clamping assembly 31 can move on the movable plate 32 when the electric push rod 366 and the second motor 361 are running, thereby adjusting the force angle of the wire harness.

[0021] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the novel mechanical performance testing device are fixed by threads. To allow for a more intuitive observation of the technical features, bolt connections are appropriately concealed in the figures. When using the novel mechanical performance testing device, the user wraps both ends of the wire harness to be tested around the shaft 241 within the first clamping component 31 and the second clamping component 24, respectively. Then, the ends of the wire harness are inserted into the corresponding rectangular slots 242. The corresponding turntables 245 are then rotated to fix the ends of the wire harness using the pressing plate 244. After the wire harness is fixed, the user can adjust the force angle of the wire harness according to the specific usage. The user only needs to start the second motor 361. Alternatively, the electric actuator 366 can be used to allow the first clamping assembly 31 to interact with the upper surface of the movable plate 32, thereby adjusting the force angle of the wire harness. The user can also start the third motor 22, which will rotate the wire harness. After adjusting the wire harness, the user can start the first motor 35 to rotate the lead screw 34, thereby causing the movable plate 32 to move backward on the slide rail 13 via the slide groove 33. At this time, the tension sensor 37 can test the mechanical tension of the wire harness. This allows the new mechanical performance testing device to not only adjust the force angle of the wire harness but also rotate it when conducting mechanical tension tests, greatly improving the practicality of the new mechanical performance testing device.

[0022] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
