Description

Technical Field

[0001] The utility model relates to the technical field of positioners, in particular to a wheel assembly positioner which is convenient for adjusting offset. Background Art

[0002] The function of wheel hub gasket is to increase the distance between two coaxial wheels, so that the outer contour of the wheel can be extended a little. It has important applications in wheel hub modification. Specifically, the gasket and the wheel are fastened by bolts, and the gasket and the wheel axle are also fastened by bolts. As the wheel moves for a long time, in order to ensure the accuracy of wheel installation, it is necessary to install a positioner for adjusting the offset of the wheel. The current installation of the positioner is also through bolt fixing. However, the movement of the wheel is often accompanied by vibration. Under the action of the vibration force, the bolt is easy to deflect, which leads to a decrease in the tightness of the bolt, affecting its installation stability. For this reason, we propose a wheel assembly positioner that is easy to adjust the offset. Utility Model Content

[0005] Optionally, the center of the cut-off baffle is connected to the annular seat via an axle pin, and a notch is provided on the outer side of the annular plate.

[0006] Optionally, a limiting spring is fixedly connected in the notch, and one end of the limiting spring is fixedly connected to the annular seat.

[0007] Optionally, the bottom of the first wedge-shaped washer and the top of the second wedge-shaped washer are provided with corresponding serrations that are meshed with each other, and opposite serrations are provided on the top of the first wedge-shaped washer and the bottom of the second wedge-shaped washer, respectively.

[0008] Optionally, the serrations on the top of the first wedge-shaped washer are embedded in the surface of the mounting bolt, and the serrations on the bottom of the second wedge-shaped washer are embedded in the surface of the bottom of the mounting groove.

[0009] The utility model has the following beneficial effects:

[0010] 1. The wheel assembly positioner that is convenient for adjusting the offset has a first wedge washer and a second wedge washer that mesh with each other and serrations on the outer sides of the first wedge washer and the second wedge washer. After locking, the serrations on the first wedge washer and the second wedge washer are respectively embedded in the surface of the mounting bolt and the surface of the bottom of the mounting groove. When the mounting bolt is vibrated and tends to loosen and rotate, since the meshing lift angle is greater than the thread lift angle on the mounting bolt, the lift generated is greater than the lift generated by the mounting bolt, and the mounting bolt is further tightened to prevent the mounting bolt from loosening, thereby achieving a better tightening effect of the mounting bolt.

[0011] 2. The wheel assembly positioner which is easy to adjust the offset enables the cut-off baffle to contact the outer side of the top of the mounting bolt under the elastic force of the limiting spring. The top of the mounting bolt is polygonal. When it is vibrated and tends to loosen and rotate, the limiting spring can provide the mounting bolt with a reverse rotation force, so that the rotation of the mounting bolt is hindered, thereby making the locking effect of the mounting bolt better.

The top end of the mounting bolt 4 is in the mounting groove 3, and an annular plate 7 is movably sleeved on the inner wall of the mounting groove 3. The annular plate 7 can be rotated in a fixed position in the mounting groove 3 and can rotate within a certain limit. A plurality of stop baffles 8 are movably connected to the inner side of the annular plate 7. The stop baffle 8 can move relative to the annular plate 7 in a fixed track, so that the stop baffle 8 and the annular plate 7 can be smoothly transmitted to ensure that the annular plate 7 can smoothly push the stop baffle 8 to contact the mounting bolt 4. One of the stop baffles 8 The end abuts against the outer side of the top end of the mounting bolt 4. When the mounting bolt 4 is vibrated and tends to loosen and rotate, the limiting spring 9 can provide the mounting bolt 4 with a reverse rotation force, so that the rotation of the mounting bolt 4 is hindered, thereby making the locking effect of the mounting bolt 4 better, and a first wedge washer 5 and a second wedge washer 6 are installed at the bottom of the mounting groove 3. The first wedge washer 5 and the second wedge washer 6 are meshed, and the meshing lift angle is greater than the thread lift angle on the mounting bolt 4. When the mounting bolt 4 is vibrated and tends to loosen and rotate, since the meshing lift angle is greater than the thread lift angle on the mounting bolt 4, the lift generated is greater than the lift generated by the mounting bolt 4, and then the mounting bolt 4 is further tightened to prevent the mounting bolt 4 from loosening, thereby making the fastening effect of the mounting bolt 4 better.
