DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] Please refer to Figure 1 , the present utility model provides a technical solution: an embodiment includes an installation assembly 1, a rotating assembly 2, and a swing arm assembly 3. The installation assembly 1 is responsible for assembling the tire rim 5, the rotating assembly 2 is responsible for driving the hub and the swing arm assembly 3 to rotate, and the swing arm assembly 3 is responsible for clamping the tire and the installed part of the rim 5. The distance between the installation assembly 1 and the rotating assembly 2 is the radius of the rim 5. The installation assembly 1, the rotating assembly 2, and the swing arm assembly 3 are all arranged on the workbench 4.

[0016] The installation component 1 includes an installation adjustment cylinder 11, an installation adjustment seat 12, a supporting adjustment seat 13, installation rollers 14 and supporting rollers 15. The installation rollers 14 and the supporting rollers 15 are arranged vertically. The fixed end of the installation adjustment cylinder 11 is fixedly connected to the supporting adjustment seat 13 through a fixed column, and the output end is fixedly connected to the installation adjustment seat 12. One end of the installation roller 14 is provided with an installation connecting rod 16 for limited rotation connection, and the installation roller 14 is rotationally connected to the installation adjustment seat 12 through the installation connecting rod 16. The supporting adjustment seat 13 is limited to slide on the workbench 4. The supporting roller 15 is connected to the supporting adjustment seat 13 through a supporting connecting rod 17. One end of the supporting connecting rod 17 is rotationally connected to the supporting roller 15 in a limited manner, and the other end is fixedly connected to the supporting adjustment seat 13. At least one side of the supporting adjustment seat 13 is fixedly provided with a limiting chute, and the workbench 4 is provided with a limiting slide rail that matches the shape of the limiting chute. The limiting slide rail and the limiting chute slide relative to each other in a limited manner, and the supporting adjustment seat 13 approaches or moves away from the rotating component 2 along the limiting chute and the limiting slide rail.

[0017] The distance between the installation roller 14 and the rotating component 2 is the radius of the wheel rim 5.

[0018] The rotating component 2 includes a rotating drive component 21, a rotating support column 22 and an assembly lifting cylinder 23. The rotating drive component 21 can be a motor. The rotating drive component 21 is arranged under the workbench 4, and the rotating drive component 21 drives the rotating support column 22 to rotate in a limited manner on the workbench 4. The rotating drive component 21 can drive the rotating support column 22 to rotate through a linkage method such as a synchronous belt and a synchronous pulley or a gear set. The output end of the assembly lifting cylinder 23 is fixedly connected to the rotating support column 22, and the outer wall of the fixed end is fixedly provided with a placement seat for placing the wheel rim 5. The assembly lifting cylinder 23 changes the height of the placement seat by lifting, so as to cooperate with the placement of wheel rims 5 with different sizes. The placement seat is suitable for placing the center points of wheel rims 5 of various shapes.

[0019] The swing arm assembly 3 includes a connecting arm 31, a fixed seat 32, a clamping seat 33 and a clamping cylinder 34. One end of the connecting arm 31 is fixedly connected to the rotating support column 22, and the other end is provided with a fixed seat 32. The fixed seat 32 is provided with a fixed table 321 for placing the rim 5 and the tire. The fixed end of the clamping cylinder 34 is fixedly connected to the connecting arm 31, and the output end drives the clamping seat 33 to rotate on the fixed seat 32. One end of the clamping seat 33 is rotationally connected to the output end of the clamping cylinder 34 in a limited manner, and the other end is provided with a clamping soft pad 331 and is arranged above the fixed table 321. The clamping seat 33 and the fixed seat 32 form a C-shaped structure. The space between the clamping soft pad 331 and the fixed table 321 is provided with the rim 5 and the tire. When the clamping seat 33 rotates, it can clamp or release the rims 5 and tires of various sizes placed on the fixed table 321. The width of the fixed table 321 is greater than the width of the mounting roller 14 and the supporting roller 15. Because the fixed table 321 and the clamping soft pad 331 can clamp the rim 5 and the tire, and the pressure applied by the clamping soft pad 331 to the rim 5 is not large, the width of the fixed table 321 can be set wider, which is convenient for placing rims 5 and tires of different diameters. The functions of the mounting roller 14 and the supporting roller 15 are to press the tire into the rim 5, so the position needs to be more precise. Excessive pressure area on the rim 5 will cause damage to the rim 5.

[0020] The working principle and usage process of the present utility model: The initial position of the swing arm assembly 3 is on one side of the mounting roller 14 and the supporting roller 15. The center of the rim 5 is placed on the placing seat, a part of the edge of the rim 5 is on the supporting roller 15, the tire is placed on the rim 5, and the user manually sleeves the tire placed on the supporting roller 15 and the fixed table 321 onto the rim 5. The mounting roller 14 descends to press the rim 5 and the tire. The clamping seat 33 clamps the rim 5 and the tire on the fixed table 321. The rotating assembly 2 works, and the swing arm assembly 3 clamps the rim 5 and the hub and rotates. The unassembled rim 5 and tire pass between the supporting roller 15 and the mounting roller 14, and the tire is stretched and sleeved into the position at the edge of the rim 5, thus completing the installation between the tire and the rim 5. In order to ensure that the tire is completely assembled with the rim 5, the rotating assembly 2 drives the swing arm assembly 3 to complete at least two round trips.

[0021] Since the swing arm assembly 3 can be used as a fulcrum for supporting the rim 5, during the installation process of the rim 5 and the tire, three parts of the rim 5 are placed on three points of the supporting roller 15, the supporting roller 15 and the fixed table 321, thus forming a movable triangle, increasing the supporting force of the equipment on the rim 5, reducing the shaking of the rim 5 during the installation process, making the installation between the rim 5 and the tire more stable, and being able to adapt to rims 5 of various sizes or shapes.

[0022] Finally, it should be noted that the above are only preferred examples of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
