Description

Technical Field

[0001] This utility model belongs to the field of tires, and specifically relates to a self-aligning device for non-pneumatic tires. Background Technology

[0002] Non-pneumatic wheels consist of an outer rim, an inner rim, and a nitrogen cylinder. The nitrogen cylinder is one of the key components of a non-pneumatic wheel, primarily serving a cushioning function. During assembly or maintenance, the nitrogen cylinder needs to be inflated. This requires concentric adjustment of the outer and inner rims to ensure that each cylinder on the tire is of consistent length during inflation.

[0003] The existing method for concentrically aligning the outer and inner rims of non-pneumatic wheels uses a shim method. During alignment, shims are placed between the outer and inner rims, with adjusting bolts pressing against the inner rim and the shims against the outer rim. Tightening or loosening the bolts adjusts the extension / retraction length of the shims, applying external force to the outer and inner rims to ensure concentricity. During adjustment, a measuring tape is used to measure the extension / retraction length of the shims at different positions; when all shims extend / retract at the same length, the outer and inner rims are concentric. This method is inefficient and labor-intensive; therefore, a device for concentrically aligning the outer and inner rims of non-pneumatic wheels is needed. Utility Model Content

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0038] A self-aligning device for a non-pneumatic wheel, comprising:

[0039] The outer rim clamping and fixing device 1 and the inner rim clamping and fixing device 2 are arranged with their geometric centers concentrically.

[0040] Multiple clamping plates are respectively installed on the outer rim clamping and fixing device 1 and the inner rim clamping and fixing device 2, and are respectively used to extend to the inner wall of the outer rim and the inner rim of the non-pneumatic wheel. The multiple clamping plates 4 on the outer rim clamping and fixing device 1 and the inner rim clamping and fixing device 2 are made to move synchronously towards each other or relative to each other with their geometric centers through the clamping plate telescopic mechanism.

[0041] A sensor detection device is used to identify whether the outer and inner rims, which are supported by multiple clamps, are in a concentric state.

[0042] Due to the concentric arrangement of the outer rim clamping and fixing device 1 and the inner rim clamping and fixing device 2, and the synchronous movement of multiple clamping plates 4, specifically, the outer clamping plate 3 on the outer rim clamping and fixing device 1 and the inner clamping plate 4 on the inner rim clamping and fixing device 2, when the outer rim and the inner rim are spread apart and supported, make the outer rim and the inner rim concentric. At this time, the adjustment work can be completed by charging the nitrogen cylinder. Moreover, during the adjustment process, the sensor detection device can identify and judge at any time to ensure the accuracy of the adjustment.

[0043] In some embodiments, the clamping plate on the outer rim clamping and fixing device 1 corresponds to the clamping plate on the inner rim clamping and fixing device 2.

[0044] The advantage of this corresponding setting is that the support points of the inner and outer rims are in the same direction, which avoids interference from external factors during adjustment, thereby improving accuracy. It also facilitates the installation of corresponding sensor detection devices. In this embodiment, the sensor detection device is a distance sensor, located between the clamping plates on the outer rim clamping and fixing device 1 and the inner rim clamping and fixing device 2. This allows for the determination of concentricity by detecting the distance between the inner clamping plate 4 and the outer clamping plate 3. Of course, calibration can also be performed through image recognition or other methods. In image recognition, it is not necessary to keep the positions of the inner clamping plate 4 and the outer clamping plate 3 consistent. However, considering both cost and overall accuracy, the aforementioned solution is preferable.

[0045] In some embodiments, the inner rim clamping and fixing device 2 is located at the front end of the outer rim clamping and fixing device 1, and the maximum outer end position and the minimum inner end position of the clamping plate on the inner rim clamping and fixing device 2 are smaller than the maximum outer end position and the minimum inner end position of the clamping plate on the outer rim clamping and fixing device 1, respectively.

[0046] The inner and outer rims must have different inner diameters. Considering the overall spatial layout of the equipment structure, the inner rim clamping and fixing device 2 is placed at the front end, and the travel range of its inner clamping plate 4 is limited, so that it is easier to adjust and control without affecting the movement trajectory of the outer clamping plate 3.

[0047] Specifically, in the following embodiments, a specific adjustment setting scheme is provided, which can not only synchronously drive the movement of the clamping plate, but also effectively limit its stroke.

[0048] In some embodiments, the clamp telescopic mechanism includes:

[0049] Rotary drive motor 9;

[0050] The drive disk 11 is located at the outer end of the drive shaft of the rotary drive motor 9;

[0051] The support plate 10 is fitted onto the drive shaft through a hole 16 opened in its center;

[0052] Multiple slide rails 15 are arranged along the movement direction of each clamping plate and are mounted on the support plate 10;

[0053] Multiple clamping plates 14 are used to install each clamping plate, and each clamping plate 14 is slidably and engagingly connected to a corresponding slide rail 15.

[0054] The guide post 13 and the arc-shaped slide groove 12 are located between each drive disk 11 and each clamping plate seat 14, and the two are slidably engaged and connected so that the rotation of the drive disk 11 drives the guide post 13 to move along the arc-shaped slide groove 12, so that each clamping plate moves synchronously outward or inward along each slide rail 15.

[0055] When setting it up, such as Figure 1 As shown, the drive disc 11 and support disc 10 of the outer rim clamping and fixing device 1 have larger radii, while the drive disc 11 and support disc 10 of the inner rim clamping and fixing device 2 have relatively smaller radii, thus matching the structural settings of the inner and outer rims. Placing the inner rim clamping and fixing device 2 in front does not affect the normal operation of the outer rim clamping and fixing device 1.

[0056] The arc-shaped groove 12 not only serves as a motion guide but also as a limiting mechanism, effectively restricting the stroke of the inner clamping plate 4 and the outer clamping plate 3, thus avoiding unnecessary design waste. Specifically, the outer end of the guide post 13 is equipped with a fastening bolt, further improving its safety and reliability.

[0057] In some embodiments, multiple slide rails are provided in four sections arranged in a cross shape. The four force directions are relatively balanced, and the structure is relatively simple.

[0058] In some embodiments, to provide a highly adjustable function, it further includes:

[0059] Lifting seat 5 is used to install outer rim clamping and fixing device 1 and inner rim clamping and fixing device 2;

[0060] The base 6 is provided with a vertical lifting mechanism 7 between it and the lifting seat 5, and rollers 8 are provided at its bottom.

[0061] In some embodiments, the lifting seat 5 is provided with a slot through which the clamping plate below another rim clamping and fixing device 1 passes.

[0062] In some embodiments, to provide the function of horizontal adjustment, it further includes:

[0063] The sliding guide rail is set along the direction of the clamping plate and is located between the lifting mechanism 7 and the base 6. The lifting mechanism 7 is driven to move along the sliding guide rail by a horizontal moving mechanism.

[0064] Its working principle is as follows:

[0065] The rotary drive motor 9 and support plate 10 in the outer rim clamping and fixing device 1 and the inner rim clamping and fixing device 2 are both fixedly installed on the lifting seat 5, serving as a support and positioning device. During the adjustment process, the rotary drive motor 9 rotates, thereby driving the drive plate 11 to rotate. Under the guidance of the guide column 13 and the arc-shaped slide groove 12, the four inner clamping plates 4 and the four outer clamping plates 3 are supported and form an abutment with the inner walls of the inner and outer rims to achieve a clamping effect. Since the four inner clamping plates 4 and the four outer clamping plates 3 are set in the same position and are distributed in a cross-shaped structure, that is, the vertical and horizontal lines are intersected, so that the force direction of the inner and outer rims is consistent, thus making it more balanced. It is also convenient to detect and identify the centering by the distance sensors installed between the corresponding inner clamping plates 4 and outer clamping plates 3, that is, the values ​​of the four distance sensors are consistent. During the nitrogen cylinder filling process, the distance sensors can still identify synchronously to determine whether the calibration effect after filling still meets the concentricity requirement.

[0066] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
