Description

Technical Field

[0001] This utility model relates to the field of automotive motor shaft testing technology, specifically a high-efficiency automotive motor shaft testing device. Background Technology

[0002] As a core component of new energy vehicles, the drive motor shaft is a crucial part of the entire drive motor, used to fix the rotor core and transmit torque. Its machining quality directly affects the performance of the new energy vehicle's power system. The machining methods and routes for motor shafts vary depending on the structure of the new energy vehicle. After machining, to ensure product quality, the dimensions of the motor shaft are checked using testing equipment. During the production and assembly process, the motor shaft extends beyond the front end cover. If the error during production is too large, it will result in inconsistent motor shaft lengths, affecting subsequent use.

[0003] Currently, the length of a motor shaft is typically measured manually using tools such as micrometers and vernier calipers. This method is cumbersome, time-consuming, labor-intensive, and inefficient. Furthermore, prolonged use can lead to significant measurement errors, affecting subsequent use. Utility Model Content

[0022] 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.

[0023] Please see Figures 1 to 5 This utility model provides a high-efficiency automotive motor shaft testing device, including a testing platform 1 and an L-shaped plate 3 connected to the rear side of the testing platform 1. The L-shaped plate 3 is connected to a testing mechanism. A rotating disk 8 is rotatably connected to the top of the testing platform 1 to improve the stability of the rotation of the rotating disk 8. A motor 13 is connected to the rotating disk 8 to drive its rotation, and multiple placement cylinders 10 are connected to the top of the rotating disk 8, with equal spacing between adjacent placement cylinders 10. The placement cylinder 10 is connected to a positioning mechanism for positioning the motor shaft. The positioning mechanism includes multiple moving blocks 15, multiple pressing posts 16, multiple second springs 20, multiple inclined grooves 22, and multiple first springs 19. The moving blocks 15 are movably connected to the placement cylinder 10, and each placement cylinder 10 has four moving blocks 15. The included angle between adjacent moving blocks 15 is 90°. The pressing posts 16 are movably connected to the moving blocks 15. The two ends of the second springs 20 are connected to the pressing posts 16 and the moving blocks 15. The first spring 19 drives the moving blocks 15 to move away from the pressing posts 16. The inclined grooves 22 are located on the moving blocks 15. The rotating disk 8 is connected to a drive mechanism for driving the multiple moving blocks 15 to move forward synchronously. The drive mechanism is connected to the inclined grooves 22.

[0024] Multiple motor shafts are placed into the placement cylinder 10, and the positioning and driving mechanisms work together to lock and fix the multiple motor shafts synchronously, improving the stability of the motor shafts. The motor 13 drives the gear 12 to rotate, which in turn drives the rotating disk 8 to rotate, so that the motor shaft is located below the detection mechanism, which facilitates the detection of the motor shaft length and is highly efficient.

[0025] The detection mechanism includes a display 4, an infrared rangefinder 5, an electric telescopic rod 6, and a lifting plate 7. The display 4 is connected to the L-shaped plate 3 and is electrically connected to the infrared rangefinder 5, which is connected to the lifting plate 7. The power output end of the electric telescopic rod 6 is connected to the lifting plate 7, and the top of the electric telescopic rod 6 is connected to the L-shaped plate 3. A limiting groove 17 is provided inside the placement cylinder 10. The limiting groove 17 is used to place the motor shaft, and the bottom of the limiting groove 17 is on the same plane as the top plane of the rotating disk 8. When the motor shaft rotates to below the lifting plate 7, the electric telescopic rod 6 drives the lifting plate 7 to descend until the lifting plate 7 contacts the top of the motor shaft. The lifting plate 7 then stops moving. The infrared rangefinder 5 detects the distance between the top surface of the rotating disk 8 and the bottom surface of the lifting plate 7 as the length of the motor shaft and feeds the detection information back to the display 4 for easy observation.

[0026] The output end face of the infrared rangefinder 5 is on the same plane as the bottom end face of the lifting plate 7.

[0027] The positioning mechanism also includes multiple guide grooves 21, which are disposed within the moving block 15 and are used to guide the pressing column 16, thereby improving the stability of the movement of the pressing column 16.

[0028] The pressing column 16 is slidably connected to the guide groove 21, and the second spring 20 is located inside the guide groove 21.

[0029] Spring 19 is located inside the placement cylinder 10, and both ends of spring 19 are connected to the moving block 15 and the placement cylinder 10. When the drive mechanism drives the moving block 15 forward, spring 19 is gradually stretched, the pressing post 16 presses against the outer wall of the motor shaft, the pressing post 16 slides against the guide groove 21, and spring 20 is gradually compressed, thereby locking and fixing the motor shaft, improving the stability of the motor shaft, and it can be used for limiting motor shafts of different diameters, making it highly applicable.

[0030] The drive mechanism includes a lifting frame 9, an electric telescopic rod 11, multiple guide columns 14, and multiple drive rings 18. The electric telescopic rod 11 is connected to the center of the rotating disk 8, and its power output end is connected to the lifting frame 9. The lifting frame 9 is connected to the top of the guide columns 14, which drive the drive rings 18 to move up and down. The drive rings 18 are slidably connected to the inclined groove 22. When the electric telescopic rod 11 drives the lifting frame 9 to descend, the lifting frame 9 drives the multiple guide columns 14 to move down synchronously. The guide columns 14 drive the drive rings 18 to move down, and the drive rings 18 slide relative to the inclined groove 22, thereby driving the moving block 15 to move forward. At this time, the spring 19 is in a stretched state. When the electric telescopic rod 11 drives the lifting frame 9 to move up, it can drive the drive rings 18 to move up. The drive rings 18 slide relative to the inclined groove 22, and the stretched spring 19 drives the moving block 15 to move backward, separating the pressing column 16 from the motor shaft. This facilitates the simultaneous loosening of multiple motor shafts and makes disassembly of the motor shafts easier.

[0031] The guide post 14 is slidably connected to the placement cylinder 10, and the bottom of the guide post 14 is connected to the drive ring 18. The guide post 14 plays a good guiding role for the drive ring 18 and improves the stability of the drive ring 18's lifting and lowering.

[0032] Motor 13 is connected to the top of the testing platform 1, and the power output end of motor 13 is connected to gear 12. Gear 12 meshes with rotating disk 8. The meshing connection has high transmission efficiency and constant transmission ratio.

[0033] The testing table 1 has placement slots 2 on both sides, which can be used to place the motor shaft to be tested, making it convenient to load the motor shaft.

[0034] Working principle: Multiple motor shafts are placed in the corresponding placement cylinders 10. The electric telescopic rod 11 drives the lifting frame 9 to move downward, causing multiple guide columns 14 to move downward synchronously. The guide columns 14 drive the drive ring 18 to move downward. The drive ring 18 slides relative to the inclined groove 22, thereby driving the moving block 15 to move forward. The spring 19 is gradually stretched, causing the pressing column 16 to press against the motor shaft. The spring 20 is gradually compressed, realizing the synchronous locking and fixing of multiple motor shafts, improving the stability of the motor shafts, and can be used for limiting motor shafts of different diameters, with strong applicability. After the motor shafts are installed, the motor 13 drives the gear 12 to rotate, causing multiple motor shafts to enter directly below the lifting plate 7 in sequence. The electric telescopic rod 6 drives the lifting plate 7 to move downward until the lifting plate 7 contacts the top of the motor shafts. The lifting plate 7 stops moving, and the infrared rangefinder 5 feeds back the detection information to the display 4 for easy observation and improved detection efficiency. After the motor shaft inspection is completed, the electric telescopic rod 11 drives the lifting frame 9 to move upward, which in turn drives the drive ring 18 to move upward. The drive ring 18 slides relative to the inclined groove 22, and the stretched spring 19 drives the moving block 15 to move backward. The pressing column 16 separates from the motor shaft, realizing the synchronous loosening of multiple motor shafts, which facilitates unloading.
