Description

Technical Field

[0001] The utility model relates to the technical field of tire rim production, and particularly relates to a tire retaining ring pressing tool. Background Art

[0002] At present, some light trucks adopt a single rear wheel design for the rear wheels. The rear wheel rims of such models have changed from the original convex type rim structure to a groove type rim. When pressing the retaining ring on such a rim, due to the change from the convex structure to the groove structure, the retaining ring loses the guiding and limiting function of the convex platform during pressing, and the retaining ring is prone to displacement during pressing, resulting in deformation and damage of the retaining ring. Summary of the Utility Model

[0003] Based on the above description, the utility model provides a tire retaining ring pressing tool, aiming to solve the problem that the retaining ring of the existing groove type rim is prone to deformation and damage during assembly.

[0004] The technical solution of the utility model to solve the above technical problems is as follows:

[0005] A tire retaining ring pressing tool, comprising:

[0006] An annular support plate;

[0007] A guiding shoulder, arranged on the outer peripheral surface of the annular support plate, and the cross-section of the guiding shoulder is conical;

[0008] A limiting boss, arranged on the side of the annular support plate close to the rim, and the limiting boss is coaxially arranged with the central hole of the annular support plate.

[0009] On the basis of the above technical solution, the utility model can be further improved as follows.

Detailed Embodiments

[0024] To facilitate the understanding of this application, the following will describe this application more comprehensively with reference to the relevant drawings. Embodiments of this application are given in the drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this application more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0026] It can be understood that spatial relationship terms such as "under", "below", "lower", "beneath", "above", "upper", etc. can be used herein to describe the relationship of one element or feature shown in the figure with other elements or features. It should be understood that in addition to the orientation shown in the figure, spatial relationship terms also include different orientations of the device during use and operation.

Therefore, the exemplary terms "under" and "below" can include both the upper and lower orientations. In addition, the device can also have other orientations (such as rotating 90 degrees or other orientations), and the spatial descriptive terms used herein are accordingly interpreted.

[0027] As used herein, the singular forms "a", "an" and "the" may also include the plural forms unless the context clearly dictates otherwise. It should also be understood that the terms "comprising" or "having" or the like specify the presence of the stated features, wholes, steps, operations, components, parts or combinations thereof, but do not preclude the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0028] Referring to the appendix Figures 1-2 As shown in FIGS. 1 and 4, the present utility model provides a technical solution: a tire retaining ring pressing tool, which includes an annular support plate 1, a guiding shoulder 2 and a limiting boss 3. The guiding shoulder 2 is arranged on the outer peripheral surface of the annular support plate 1, and the cross-section of the guiding shoulder 2 is conical; the limiting boss 3 is arranged on one side of the annular support plate 1 close to the steel ring 300, and the limiting boss 3 is coaxially arranged with the central hole of the annular support plate 1.

[0029] In this embodiment, the press-fitting tool 100 is placed entirely on the steel ring 300, so that the limiting boss 3 is exactly located in the positioning hole of the steel ring 300. Then, the retaining ring 200 is placed on the guiding shoulder 2. During press-fitting, the press claws of the press-fitting machine apply a force to the retaining ring 200, causing the retaining ring 200 to slide along the guiding shoulder 2 towards the steel ring 300. At this time, the guiding shoulder 2 transmits the applied force to the annular support plate 1 and the limiting boss 3 in sequence, making the limiting boss 3 fit tightly with the steel ring 300. The limiting boss 3 can play both a limiting role and a supporting role. As the retaining ring 200 continues to slide, the retaining ring 200 reaches the steel ring 300 and enters the installation groove of the steel ring 300 to complete the assembly of the retaining ring 200 and the steel ring 300. In this way, through the guiding function of the guiding shoulder 2, the guiding effect on the retaining ring 200 during press-fitting effectively prevents the retaining ring 200 from shifting and deforming, reducing the damage rate of the press-fitting of the retaining ring 200.

[0030] Refer to the attached Figures 1-2 As shown, in some embodiments, a plurality of first weight-reducing holes 11 are provided on the annular support plate 1 at intervals around the axis of the central hole.

[0031] In this embodiment, the first weight-reducing holes 11 can reduce the self-weight of the press-fitting tool 100, facilitating the operator to pick it up. During operation, the operator can place the press-fitting tool 100 on the steel ring 300 through the first weight-reducing holes 11. At the same time, the position of the limiting boss 3 can be directly seen through the first weight-reducing holes 11, facilitating the positioning of the limiting boss 3 and the steel ring 300.

[0032] Refer to the attached Figures 1-2 As shown, in some embodiments, the limiting boss 3 is provided with second weight-reducing holes 31 extending axially.

[0033] In this embodiment, the second weight-reducing holes 31 can reduce the self-weight of the press-fitting tool 100. At the same time, the position of the limiting boss 3 can be directly seen through the second weight-reducing holes 31, facilitating the positioning of the limiting boss 3 and the steel ring 300.

[0034] Refer to the attached Figure 1 and 3 As shown, in some embodiments, it includes a plurality of reinforcing rods 4. All the reinforcing rods 4 are arranged on the side of the annular support plate 1 close to the steel ring 300, and all the reinforcing rods 4 are arranged at intervals around the axis of the limiting boss 3.

[0035] In this embodiment, as the annular support plate 1 is repeatedly used, when the force received by the guiding shoulder 2 is transmitted to the limiting boss 3, the annular support plate 1 gradually undergoes concave deformation. Therefore, the reinforcing rods 4 play a supporting role for the annular support plate 1 during press-fitting to prevent the annular support plate 1 from deforming.

[0036] Refer to the attached Figure 1 and3 As shown, in some embodiments, the reinforcing rod 4 is a telescopic rod 41, and a locking device 42 is provided between the cylinder body 411 and the movable rod 412 of the telescopic rod 41.

[0037] In this embodiment, since the depths or slopes of the inner inclined surfaces of the steel rings 300 in different batches are different, the telescopic rod 41 can be adjusted adaptively, improving the adaptability of the press-fitted workpiece.

[0038] Refer to the attached Figure 1 and 3 As shown, in some embodiments, it includes a plurality of buffer pads 5, and the buffer pads 5 are respectively arranged at one end of the movable rod 412 away from the cylinder body 411.

[0039] Exemplarily, the buffer pad 5 can be made of silicone material or the like.

[0040] In this embodiment, due to the slope of the inner inclined surface of the steel ring 300, it is difficult for the movable rod 412 to fit closely, resulting in the movable rod 412 being unable to support the annular support plate 1 well. Therefore, through the elastic property of the buffer pad 5, the buffer pad 5 can be deformed according to the slope of the inner inclined surface of the steel ring 300, so that the buffer pad 5 fits closely with the inner inclined surface of the steel ring 300, ensuring that the reinforcing rod 4 exerts a supporting force on the annular support plate 1.

[0041] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
