Description

Technical Field

[0001] This utility model relates to the field of wheel hub manufacturing technology, and more specifically, to a motorcycle wheel hub testing device. Background Technology

[0002] During the production of existing motorcycle wheel hubs, radial runout needs to be tested. The test involves inserting a locating shaft into the hub's bore, with the end of a dial indicator's measuring rod contacting the outer circumference of the hub. The hub is rotated one revolution, and the change in the dial indicator reading is observed. To insert the locating shaft into the hub's bore, a gap must be maintained between the locating shaft and the bore. When the hub is mounted on the locating shaft, gravity causes the hub to press against the upper part of the locating shaft, resulting in a larger gap between the lower part of the locating shaft and the lower part of the bore. This misalignment between the hub and the locating shaft affects the test results. 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] like Figures 1-5 As shown, a motorcycle wheel hub inspection device includes a housing 1. A lifting plate 3 is mounted inside the housing 1 via a lifting mechanism 2, which is either a hydraulic cylinder or a pneumatic cylinder. A rotating shaft 10 is rotatably mounted on the lifting plate 3. A retaining ring 11 is mounted on the rear of the rotating shaft 10, and a washer 22 is mounted on the front side of the retaining ring 11. A fixing nut 12 is threaded to the front end of the rotating shaft 10. A retaining ring 20 is located behind the fixing nut 12, and several pads 21 are located behind the retaining ring 20. The washer 22 and pads 21 are made of rubber and, through contact with the wheel hub, protect the wheel hub.

[0024] A guide hole 28 is provided on the outer periphery of the rotating shaft 10. A moving block 29 is provided inside the guide hole 28. A stop block 32 is connected to the portion of the moving block 29 located inside the rotating shaft 10. An adjusting shaft 25 is provided inside the rotating shaft 10. A frustum block 26 is connected to the adjusting shaft 25. The diameter of the front end of the frustum block 26 is smaller than the diameter of the rear end. A guide slope 31 is provided on the inner side of the moving block 29. The inclination of the guide slope 31 is adapted to the outer peripheral surface of the frustum block 26. The guide slope 31 can abut against the outer peripheral surface of the frustum block 26. A translation mechanism is provided on the rear plate 4. The translation mechanism drives the adjusting shaft 25. A support frame 13 is installed on the chassis 1. A mounting frame 14 is provided on the upper part of the support frame 13. A dial indicator 15 is installed on the mounting frame 14.

[0025] At least three guide holes 28 are provided, and the three guide holes 28 are evenly distributed on the outer circumference of the rotating shaft 10.

[0026] Initially, the adjusting shaft 25 is in a rearward position, and the front end of the frustum block 26 is positioned corresponding to the moving block 29. The moving block 29 can move along the guide hole 28 and retract into it. The upper moving block 29 falls into the guide hole 28 due to gravity, while the lower moving block 29 extends out of the guide hole 28 due to gravity and is limited by the stop block 32. The hub's shaft hole is inserted into the rotating shaft 10, pressing the lower moving block 29 into the rotating shaft 10 while simultaneously pressing the hub inward, so that the moving block 29 is inside the hub's shaft hole. After one end of the hub's shaft hole abuts against the retaining ring 11, the adjusting shaft 25 is driven forward by the translation mechanism. Through the cooperation of the outer circumferential surface of the frustum block 26 and the guide inclined surface 31, the moving block 29 is pushed outward, causing the protective block 30 to abut against the inner wall of the shaft hole. This achieves both fixing and centering of the hub, ensuring that the hub's shaft hole is concentric with the rotating shaft 10, preventing the hub from becoming eccentric during rotation. The lifting mechanism 2 drives the lifting plate 3 to rise, causing the outer circumference of the wheel hub to contact the measuring rod head of the dial indicator 15. The wheel hub is rotated, and the change in the reading of the dial indicator 15 is observed for testing.

[0027] A spring can be installed between the inner side of the side arm of the rotating shaft 10 and the moving block 29. Under the action of the spring, the moving block 29 tends to move inward, so that when the front end of the frustum block 26 is located at the position corresponding to the moving block 29, the moving block 29 can retract into the guide hole 28 under the action of the spring.

[0028] A protective block 30 is provided on the outside of the movable block 29. The protective block 30 is fixedly installed on the movable block 29 by screws. For hubs with shaft holes of different inner diameters, a protective block 30 of appropriate thickness is selected to ensure that it abuts against the inner wall of the shaft hole and increases the application range of this device.

[0029] The translation mechanism includes a threaded seat 23 located on the rear side of the rear plate 4. An adjusting screw 24 is internally threaded onto the threaded seat 23, and an adjusting shaft 25 is rotatably mounted at the front end of the adjusting screw 24. Rotating the adjusting screw 24 adjusts its position, thereby moving the adjusting shaft 25 within the rotating shaft 10. Simultaneously, the adjusting shaft 25 and the adjusting screw 24 are rotatably connected, allowing the adjusting shaft 25 to rotate together with the rotating shaft 10. A handle 27 is mounted at the rear end of the adjusting screw 24, allowing for convenient rotation of the adjusting screw 24.

[0030] A support hole is provided at the front position inside the rotating shaft 10, and the front end of the adjusting shaft 25 is inserted into the support hole. The support hole supports the front end of the adjusting shaft 25 to prevent the adjusting shaft 25 from tilting.

[0031] The front and rear sides of the upper part of the lifting plate 3 are respectively connected to a front plate 5 and a rear plate 4. The front plate 5 and the rear plate 4 are vertically arranged, and two mounting shafts 6 are installed between the rear plate 4 and the front plate 5. Support rollers 7 are rotatably mounted on the mounting shafts 6. During the process of putting the wheel hub onto the rotating shaft 10, the support rollers 7 can support the wheel hub.

[0032] Oval holes 8 are provided at corresponding positions on the front plate 5 and the rear plate 4. The length of the oval holes 8 is horizontal. The front and rear ends of the mounting shaft 6 pass through the oval holes 8 on the front plate 5 and the rear plate 4, respectively. The portion of the mounting shaft 6 that passes through the oval holes 8 is threadedly connected to a fixing nut 9. The installation of the washer 19 facilitates the installation, fixing, and removal of the mounting shaft 6. The oval holes 8 allow the position of the mounting shaft 6 to be adjusted, thereby changing the distance between the two support rollers 7 and the distance between the support rollers 7 and the rotating shaft 10, which can effectively support motorcycle wheel hubs within a certain diameter range.

[0033] A washer 19 is fitted onto the portion of the mounting shaft 6 that protrudes from the oblong hole 8. The washer 19 is located inside the fixing nut 9. By setting the washer 19, the contact area is increased, which can better achieve the fixation and at the same time reduce the pressure damage to the rear plate 4 and the front plate 5.

[0034] A guide rod 17 is connected to the lower part of the lifting plate 3, and a guide sleeve 18 is provided inside the housing 1. The lower end of the guide rod 17 is inserted into the guide sleeve 18. Both the guide rod 17 and the guide sleeve 18 are vertically arranged. The lifting plate 3 is guided by the cooperation of the guide rod 17 and the guide sleeve 18 to ensure that the lifting plate 3 moves in a vertical state.

[0035] A bearing is provided on the rear plate 4, and the rotating shaft 10 is mounted on the bearing. Specifically, the bearing includes an outer ring 33 and an inner ring 34. The outer ring 33 is fixedly mounted on the rear plate 4. The rotating shaft 10 includes a shoulder 35. The front end of the inner ring 34 abuts against the shoulder 35. A retaining ring 36 is installed at the rear end of the rotating shaft 10. The rear end of the inner ring 34 abuts against the retaining ring 36, thereby realizing the rotational connection between the rotating shaft 10 and the rear plate 4.

[0036] Both sides of the chassis 1 are equipped with ramps 16, which facilitates the wheel hub to be rolled onto the chassis 1 along the ramps 16, and the wheel hub to be rolled off the chassis 1 along the ramps 16 after the test is completed.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
