[0013] 1. This utility model, by setting a fixing component, allows for the testing of the rear axle. One end of the rear axle is placed in the second fixing plate, and then the throttle is turned. The rotation of the throttle causes the screw to rotate in one end of the frame via a worm gear. The rotation of the screw pushes the moving plate through the threaded cylinder, while the telescopic rod extends and retracts. The movement of the moving plate pushes the first fixing plate to the other end of the rear axle. The first fixing plate and the second fixing plate clamp and fix the rear axle. Then, the first motor is turned on to drive the speed detector and the second fixing plate to rotate, thereby driving the rear axle to rotate. The speed detector detects the speed of the rear axle.

[0014] 2. This utility model, by setting an adjustment component, turns on the second motor to drive the lead screw to rotate. The rotation of the lead screw causes the slide plate to move in the rectangular groove. When the slide plate moves, the protrusions at both ends slide in the groove, thereby making the movement of the slide plate more stable. The movement of the slide plate causes the first screw and the fixed clamping ring to move, thereby moving and adjusting the position of the pressure detector. By setting the adjustment component, the pressure detector can be moved and adjusted, which is convenient for load detection at different positions of the rear axle. Attached Figure Description

[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] Example 1

[0022] Please see Figure 1-4This utility model provides the following technical solution: A testing platform for aluminum rear axle products, including a frame 1, a screw 4 on the upper side of the frame 1, a fixed clamping ring 8 rotatably connected to the lower end of the screw 4, a pressure detector 5 installed in the fixed clamping ring 8, a data calculator 6 installed on the upper side of one end of the frame 1, a motor 7 installed on the lower side of one end of the frame 1 at a position corresponding to the fixed clamping ring 8, a speed detector 9 installed at the output end of the motor 7, the screw 4 and the frame 1 are connected by an adjusting component 3, and a fixing component 2 for clamping and fixing the rear axle is provided at one end of the speed detector 9.

[0023] Specifically, the fixing assembly 2 includes a fixing disc 21, a threaded cylinder 22, a telescopic rod 23, a moving plate 24, a fixing disc 25, a screw 26, a fixing plate 27, a rotating rod 28, a worm gear 29, a turbine 210, and a throttle 211. The speed detector 9 has the fixing disc 25 mounted on one end. The end of the frame 1 away from the motor 7 is rotatably connected to the screw 26 at a position corresponding to the fixing disc 25. The end of the screw 26 away from the fixing disc 25 is fixed to the turbine 210. One end of the frame 1 is aligned with the turbine 210. Two fixed plates 27 are fixed in the corresponding positions. A rotating rod 28 is rotatably connected between the two fixed plates 27. A handle 211 is fixed to one end of the rotating rod 28. A worm gear 29 is fixed to the surface of the rotating rod 28 at the position corresponding to the turbine 210. A movable plate 24 is provided on the side of the screw 26 near the fixed plate 25. The other end of the movable plate 24 is rotatably connected to the fixed plate 1. A telescopic rod 23 is fixed on the upper side between the movable plate 24 and the frame 1. A threaded cylinder 22 is fixed to one end of the movable plate 24 at the position corresponding to the screw 26.

[0024] By adopting the above technical solution, when testing the rear axle, one end of the rear axle is placed in the second fixed plate 25, and then the rotating rod 28 is rotated by the throttle 211. The rotation of the rotating rod 28 drives the second screw 26 to rotate in one end of the frame 1 through the worm gear 29. The rotation of the second screw 26 pushes the moving plate 24 to move through the threaded cylinder 22. At the same time, the telescopic rod 23 extends and retracts. The movement of the moving plate 24 pushes the first fixed plate 21 to move to the other end of the rear axle. The first fixed plate 21 cooperates with the second fixed plate 25 to clamp and fix the rear axle. Then, the first motor 7 is turned on to drive the speed detector 9 and the second fixed plate 25 to rotate, thereby driving the rear axle to rotate. The speed of the rear axle is detected by the speed detector 9. The fixed component 2 is set to facilitate the fixing of rear axles of different lengths, thereby facilitating the speed detection of rear axles of different lengths.

[0025] Specifically, bearing rotating seats are provided between the screw 26 and the frame 1, and between the fixed plate 21 and the moving plate 24. The worm 29 and the rotating rod 28 are welded as a whole structure.

[0026] By adopting the above technical solution, the screw 26 can rotate in the frame 1, the fixed plate 21 can rotate on the moving plate 24, and the worm 29 and the rotating rod 28 are welded as a whole structure, which is more robust and durable.

[0027] Specifically, the telescopic rod 23 is spot-welded to the movable plate 24 and to the frame 1. When the telescopic rod 23 is extended to its maximum length, the threaded cylinder 22 and the screw rod 26 do not separate.

[0028] By adopting the above technical solution, spot welding makes the telescopic rod 23 and the movable plate 24, as well as the telescopic rod 23 and the frame 1, more secure. The telescopic rod 23 can limit the movement between the threaded cylinder 22 and the screw 26.

[0029] In this embodiment, when using the aluminum rear axle product testing platform, the device is installed in a suitable position. When testing the rear axle, one end of the rear axle is placed in the second fixed plate 25. Then, the rotating rod 28 is rotated by the throttle 211. The rotation of the rotating rod 28 drives the second screw 26 to rotate in one end of the frame 1 through the worm gear 29. The rotation of the second screw 26 pushes the moving plate 24 to move through the threaded cylinder 22. At the same time, the telescopic rod 23 extends and retracts. The movement of the moving plate 24 pushes the first fixed plate 21 to move to the other end of the rear axle. The first fixed plate 21 cooperates with the second fixed plate 25 to clamp and fix the rear axle. Then, the first motor 7 is turned on to drive the speed detector 9 and the second fixed plate 25 to rotate, thereby driving the rear axle to rotate. The speed of the rear axle is detected by the speed detector 9. The fixed component 2 is set to facilitate the fixing of rear axles of different lengths, thus facilitating the speed detection of rear axles of different lengths. After the speed detection, the first screw 4 is rotated to move downwards and the fixing clamp 8 is put on the rear axle. The screw 4 is rotated to press the rear axle. The load of the rear axle can be detected by the pressure detector 5.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the adjustment component 3 includes a rectangular groove 31, a second motor 32, a lead screw 33, a sliding plate 34, a protrusion 35, a groove 36, and a screw hole 37. The upper end of the frame 1 has a rectangular groove 31. The second motor 32 is installed on the upper side of one end of the frame 1 at a position corresponding to the rectangular groove 31. The output end of the second motor 32 is provided with a lead screw 33. The surface of the lead screw 33 is threadedly connected to the sliding plate 34 at a position corresponding to the first screw 4. The sliding plate 34 has a screw hole 37 corresponding to the first screw 4. The two ends of the sliding plate 34 are fixed with protrusions 35. The two ends of the rectangular groove 31 have grooves 36 corresponding to the protrusions 35.

[0032] By adopting the above technical solution, the motor 32 drives the lead screw 33 to rotate. The rotation of the lead screw 33 causes the slide plate 34 to move in the rectangular groove 31. When the slide plate 34 moves, the protrusions 35 at both ends slide in the slide groove 36, thereby making the movement of the slide plate 34 more stable. The movement of the slide plate 34 drives the screw 4 and the fixed clamping ring 8 to move, thereby adjusting the position of the pressure detector 5. By setting the adjustment component 3, the pressure detector 5 can be adjusted, which facilitates load detection at different positions of the rear axle.

[0033] Specifically, the protrusion 35 and the slide plate 34 are spot welded together, and the side of the protrusion 35 is in close contact with the inner wall of the slide groove 36, while the two ends of the slide plate 34 are in close contact with the inner wall of the rectangular groove 31.

[0034] By adopting the above technical solution, the protrusion 35 and the slide plate 34 are more firmly connected, and the movement of the slide plate 34 and the protrusion 35 is more stable and less prone to displacement and shaking.

[0035] In this embodiment, when the motor 32 is turned on, the lead screw 33 is driven to rotate. The rotation of the lead screw 33 causes the slide plate 34 to move in the rectangular groove 31. When the slide plate 34 moves, the protrusions 35 at both ends slide in the slide groove 36, so that the movement of the slide plate 34 is more stable. The movement of the slide plate 34 causes the screw 4 and the fixing clamp 8 to move, thereby adjusting the position of the pressure detector 5. The pressure detector 5 can be adjusted by setting the adjustment component 3, which facilitates load detection at different positions of the rear axle.

[0036] In this utility model, the motor 232 is a previously disclosed technology, and the selected model is 5IK120GN-CF.

[0037] The structure and working principle of the frame 1, screw 4, pressure detector 5, data calculator 6, motor 7, fixing clamp 8 and speed detector 9 in this utility model have been disclosed in a rear axle detection device for an electric tricycle disclosed in Chinese patent application number 2020210362353.

[0038] The working principle and usage process of this utility model: When using the aluminum rear axle product testing platform, the device is installed in a suitable position. When testing the rear axle, one end of the rear axle is placed in the fixed plate 25. Then, the rotating rod 28 is rotated by the throttle 211. The rotation of the rotating rod 28 drives the screw 26 to rotate in one end of the frame 1 through the worm gear 29. The rotation of the screw 26 pushes the moving plate 24 to move through the threaded cylinder 22. At the same time, the telescopic rod 23 extends and retracts. The movement of the moving plate 24 pushes the fixed plate 21 to move to the other end of the rear axle. The fixed plate 21, together with the fixed plate 25, clamps and fixes the rear axle. Then, the motor 7 is turned on to drive the speed detector 9 and the fixed plate 25 to rotate, thereby driving the rear axle to rotate. The speed of the rear axle is detected by the speed detector 9. By setting the fixing component 2, the rear axle can be rotated. To fix the rear axles of different lengths, it is convenient to perform speed detection on the rear axles of different lengths. After speed detection, the screw 4 is rotated downwards and the fixing clamp 8 is fitted onto the rear axle. The screw 4 is rotated to compress the rear axle. The load on the rear axle can be detected by the pressure detector 5. The motor 32 is turned on to drive the lead screw 33 to rotate. The rotation of the lead screw 33 drives the slide plate 34 to move in the rectangular groove 31. When the slide plate 34 moves, the protrusions 35 at both ends slide in the slide groove 36, so that the movement of the slide plate 34 is more stable. The movement of the slide plate 34 drives the screw 4 and the fixing clamp 8 to move, thereby adjusting the position of the pressure detector 5. The pressure detector 5 can be adjusted by setting the adjustment component 3, which facilitates load detection at different positions of the rear axle.
