Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, specifically a torsion testing device for automotive drive shafts. Background Technology

[0002] In automotive transmission systems, the driveshaft, as a key component for transmitting power, directly affects the vehicle's power transmission efficiency and driving safety due to its torsional performance. Currently, most devices on the market for testing the torsional performance of automotive driveshafts have relatively fixed structures, making it difficult to quickly and accurately adjust the testing position when testing driveshafts of different specifications, resulting in low testing efficiency.

[0003] For example, some testing devices require a crane for lifting heavy automotive driveshafts. During lifting, the driveshaft wobbles, necessitating multiple personnel for securing and aligning it. This makes the installation process cumbersome, increasing manual labor difficulty and time costs. Furthermore, existing testing devices lack effective leveling structures during driveshaft installation, making it difficult to ensure the driveshaft is horizontal during testing. This significantly impacts the accuracy of the test results, leading to large errors and failing to provide reliable data for evaluating the performance of automotive driveshafts. Utility Model Content

[0004] To address the shortcomings mentioned in the background art, the purpose of this utility model is to provide a torsion detection device for automotive drive shafts. By setting a concave structure, the drive shaft can naturally roll onto the leveling plate after being hoisted to the top of the housing, avoiding the tedious manual alignment operation during hoisting. Combined with the lifting component and the leveling component, the installation position of the drive shaft can be adjusted quickly and accurately, greatly improving the installation efficiency of the drive shaft and reducing the difficulty and time cost of manual operation.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A torsion detection device for an automotive driveshaft includes a housing. A loading device and a support plate are symmetrically arranged on the top of the housing. A chuck is provided at the output end of the loading device and on the support plate. An installation mechanism is provided on the housing. The installation mechanism includes a lifting assembly and a leveling assembly located at the output end of the lifting assembly. The lifting assembly includes a screw rotatably mounted on the inner wall of the housing. A threaded sleeve is threaded onto the screw, and a lifting rod is fixedly connected to the threaded sleeve. Telescopic support structures are provided between the two ends of the lifting rod and the bottom end of the inner wall of the housing.

[0007] More preferably, the telescopic support structure includes a base rod and a sliding rod. The base rod is fixedly installed on the bottom end of the inner wall of the chassis, and the sliding rod is slidably sleeved on the base rod. The side of the sliding rod is in contact with the side of the base rod, and the top end of the sliding rod is fixedly connected to the end of the lifting rod.

[0008] More preferably, the lifting assembly further includes a drive motor fixedly installed at the bottom of the inner wall of the chassis, the output end of the drive motor is fixedly connected to a bevel gear one, and the bottom of the screw is provided with a bevel gear two that meshes with the bevel gear one.

[0009] More preferably, the leveling assembly includes two symmetrically arranged sleeve rods, which are slidably sleeved on the top of the slide rod. A sliding groove is provided on one side of the sleeve rod, and the lifting rod passes through the sliding groove. A through hole is provided on the top of the housing, and the top of the lifting rod passes through the through hole and is fixedly connected to a leveling plate.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0024] like Figure 1-4 As shown, an automotive driveshaft torsion testing device includes a housing 1. A loading device 2 and a support plate 3 are symmetrically arranged on the top of the housing 1. Both the output end of the loading device 2 and the support plate 3 are equipped with chucks 4. The chucks 4 are used to securely fix both ends of the automotive driveshaft. The loading device 2 can apply torsional force to the driveshaft, while the support plate 3 supports the driveshaft, ensuring the stability of the testing process.

[0025] The chassis 1 is provided with an installation mechanism 5, which consists of a lifting component 6 and a leveling component 7 located at the output end of the lifting component 6.

[0026] Lifting component 6;

[0027] The lifting assembly 6 includes a screw 8 rotatably mounted on the inner wall of the housing 1. A threaded sleeve 9 is threaded onto the screw 8, and the threaded sleeve 9 is fixedly connected to the lifting rod 10. When the screw 8 rotates, the threaded sleeve 9 moves along the screw 8, thereby driving the lifting rod 10 to move up and down. Telescopic support structures 11 are provided between the two ends of the lifting rod 10 and the bottom end of the inner wall of the housing 1.

[0028] The telescopic support structure 11 consists of a base rod 12 and a sliding rod 13. The base rod 12 is fixedly installed on the bottom end of the inner wall of the housing 1. The sliding rod 13 is slidably sleeved on the base rod 12, with the side of the sliding rod 13 fitting against the side of the base rod 12. The top end of the sliding rod 13 is fixedly connected to the end of the lifting rod 10. The function of the telescopic support structure 11 is to support the lifting rod 10, ensuring its stability during vertical movement and preventing the lifting rod 10 from swaying or tilting, thereby ensuring that the leveling plate 20 can be raised and lowered smoothly.

[0029] The lifting assembly 6 also includes a drive motor 14 fixedly installed at the bottom of the inner wall of the housing 1. The output end of the drive motor 14 is fixedly connected to a bevel gear 15, and the bottom of the screw 8 is provided with a bevel gear 16 that meshes with the bevel gear 15. After the drive motor 14 is started, it drives the screw 8 to rotate through the meshing transmission of the bevel gear 15 and the bevel gear 16, thereby realizing the lifting of the lifting rod 10 and providing power for the height adjustment of the transmission shaft.

[0030] Leveling component 7;

[0031] The leveling assembly 7 includes two symmetrically arranged sleeve rods 17, which are slidably fitted onto the top of the slide rod 13. A groove 18 is formed on one side of each sleeve rod 17, through which the lifting rod 10 passes. A through hole 19 is formed on the top of the housing 1, through which the top of the lifting rod 10 passes and is fixedly connected to a leveling plate 20. When the leveling plate 20 is in its lowest position, it is located inside the through hole 19. The sleeve rods 17 can slide on the slide rod 13, and by adjusting the position of the sleeve rods 17, the height of the leveling plate 20 can be finely adjusted to achieve horizontal adjustment of the drive shaft.

[0032] A threaded hole 21 is provided on one side of the sleeve rod 17. A fixing screw 22 is connected to the threaded hole 21. One end of the fixing screw 22 is in contact with the outer surface of the slide rod 13 to fix the position of the sleeve rod 17, prevent the sleeve rod 17 from sliding during the testing process, and ensure the stability of the finding plate 20.

[0033] Concave structure 23;

[0034] The top of the chassis 1 has a concave structure 23 that is recessed downwards, and the through hole 19 is located at the lowest point of the concave structure 23. The purpose of this design is that when the drive shaft is hoisted to the top of the chassis 1, the drive shaft can naturally roll to the lowest point of the concave structure 23 by its own weight, that is, above the leveling plate 20, thereby avoiding the trouble of manually aligning the leveling plate 20 precisely during hoisting, and greatly improving the installation efficiency. Furthermore, the top of the leveling plate 20 is set as an arc surface to prevent the drive shaft from rolling off the leveling plate 20.

[0035] Working principle:

[0036] Using a crane, the car drive shaft is hoisted to the top of the chassis 1. The drive shaft will naturally roll to the lowest point of the concave structure 23 on the top of the chassis 1, that is, directly above the plate 20.

[0037] Start the drive motor 14, which drives the first bevel gear 15 to rotate. The first bevel gear 15 meshes with the second bevel gear 16, causing the screw 8 to rotate.

[0038] When the screw 8 rotates, the screw sleeve 9 moves on the screw 8, causing the lifting rod 10 to rise. The sliding rods 13 at both ends of the lifting rod 10 slide on the base rod 12 to ensure the stability of the lifting. As the lifting rod 10 rises, the flat plate 20 raises the drive shaft to a suitable height, so that both ends of the drive shaft are close to the chuck 4.

[0039] Observe the horizontal state of the drive shaft, adjust the position of the sleeve rod 17 on the slide rod 13 to make the drive shaft horizontal, and then tighten the fixing screw 22 to fix the position of the sleeve rod 17.

[0040] Use chuck 4 to fix both ends of the drive shaft to the output end of the loading device 2 and the support plate 3 respectively, ensuring a secure fixation.

[0041] Start loading device 2. The output end of loading device 2 applies a torsional force to the drive shaft to begin torsion testing. During the testing process, observe the relevant test data and record the test results.

[0042] After the inspection is completed, close the loading device 2, release the chuck 4, and remove the drive shaft from the device. Lower the leveling plate 20 to its lowest position, positioning it inside the through hole 19, to prepare for the next inspection.
