Description

Double-roller assembly for tire press

The technical field is as follows:

the utility model belongs to the technical field of the pressure child equipment, refer in particular to a double-roller subassembly for pressing child machine.

Background art:

the tire press is a tire dismounting device for dismounting a tire and a hub, and in the actual use process, the tire and the hub are placed on a workbench and are pressed on the tire by rollers to rotate in the circumferential direction, so that the operation of mounting the hub on the tire is realized.

However, because the inner ring peripheral side wall of the tire is of a conical surface structure, the existing roller is abutted against the tire, but the contact area is small, acting force cannot be effectively applied to the tire, and the tire mounting operation is not facilitated.

The invention content is as follows:

the utility model aims at providing a two gyro wheels subassemblies for pressing child machine, its gyro wheel that adopts two outer peripheral faces to be the conical surface is used for supporting pressing on the tire for the area of contact of gyro wheel and tire obtains effective increase, so that the dress child operation of pressing the child machine.

The utility model discloses a realize like this:

the utility model provides a double-roller subassembly for tire press, is including fixing the guide wheel pole on the tire press, and the bottom of guide wheel pole is provided with the universal driving shaft, rotates on the universal driving shaft to be connected with small roller and big gyro wheel, and the outer peripheral face of small roller and big gyro wheel all is conical surface structure, and the maximum external diameter of small roller is less than or equal to the maximum external diameter of big gyro wheel.

In the above double-roller assembly for a tire press, the outer peripheral surfaces of the small roller and the large roller are located on the same conical table surface.

In the double-roller assembly for the tire press, the linkage shaft is arranged on the guide wheel rod in a penetrating manner, and the small roller and the large roller are respectively sleeved at the end parts of two ends of the linkage shaft.

In the double-roller assembly for the tire press, ball bearings are arranged between the small roller and the linkage shaft, and between the large roller and the linkage shaft.

In the double-roller assembly for the tire press, the guide wheel rod is provided with an irregular hole for the linkage shaft to penetrate through, and one end part of the linkage shaft corresponds to the structure and the size of the irregular hole.

Compared with the prior art, the utility model outstanding advantage is:

the utility model discloses the radial inside of tire can be followed to little gyro wheel and big gyro wheel and support in proper order and press on the tire to the outer peripheral face of two gyro wheels is the conical surface, can laminate mutually with the lateral wall that the inner circle periphery of tire corresponds, has effectively increased the area of contact of gyro wheel with the tire, so that press the dress child operation of child machine.

Description of the drawings:

fig. 1 is an overall perspective view of the present invention;

fig. 2 is an overall sectional view of the present invention;

fig. 3 is a perspective view of the guide wheel rod of the present invention.

In the figure: 1. a guide wheel rod; 2. a linkage shaft; 3. a small roller; 4. a large roller; 5. a ball bearing; 6. irregular holes.

The specific implementation mode is as follows:

the invention will now be further described with reference to specific embodiments, with reference to figures 1 to 3:

the utility model provides a double-roller subassembly for tire press, is including fixing guide wheel pole 1 on the tire press, and the bottom of guide wheel pole 1 is provided with universal driving shaft 2, rotates on the universal driving shaft 2 and is connected with small roller 3 and big gyro wheel 4, and the outer peripheral face of small roller 3 and big gyro wheel 4 all is conical surface structure, and the biggest external diameter of small roller 3 is less than the biggest external diameter that is equal to big gyro wheel 4.

Namely the utility model discloses little gyro wheel 3 can support in proper order along the radial inside of tire with big gyro wheel 4 and press on the tire to the outer peripheral face of two gyro wheels is the conical surface, can laminate mutually with the lateral wall that the inner circle periphery of tire corresponds, has effectively increased the area of contact of gyro wheel with the tire, so that press the dress child operation of child machine.

Meanwhile, in order to enable the small roller 3 and the large roller 4 to be attached to corresponding side walls of the tire at the same time and avoid the mutual influence between the small roller 3 and the large roller 4, the outer peripheral surfaces of the small roller 3 and the large roller 4 are located on the same conical table surface.

Furthermore, the small roller 3 and the large roller 4 can be both disposed at the same side position of the guide wheel rod 1, and in this embodiment, the small roller 3 and the large roller 4 are respectively disposed at two sides of the guide wheel rod 1, that is, the linkage shaft 2 is disposed on the guide wheel rod 1 in a penetrating manner, and the small roller 3 and the large roller 4 are respectively sleeved at two end portions of the linkage shaft 2.

In addition, in order to ensure that the small roller 3 and the large roller 4 can roll on the corresponding side wall of the tire so as not to influence the normal operation of tire mounting, a ball bearing 5 is arranged between the small roller 3 and the large roller 4 and the linkage shaft 2.

In addition, in order to facilitate assembly of the linkage shaft 2 and avoid circumferential rotation of the linkage shaft 2 relative to the guide wheel rod 1, an irregular hole 6 for the linkage shaft 2 to penetrate is formed in the guide wheel rod 1, and one end of the linkage shaft 2 corresponds to the structure and the size of the irregular hole 6.

The above-mentioned embodiment is only one of the preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so: all equivalent changes made according to the shape, structure and principle of the utility model are covered within the protection scope of the utility model.
