Description

Technical Field

[0001] The utility model relates to the technical field of tire clamping and limiting, in particular to a rubber tire clamping and limiting mechanism. Background Art

[0002] A tire is a circular elastic rubber product installed on various vehicles or machinery and in contact with the ground for rolling. After the tire is installed, it can support the vehicle body and ensure the driving performance of the vehicle. When the tire is in processing, production or weighing, a positioning device is required to position the tire.

[0003] In a Chinese utility model patent with the publication number CN219726165U, a tire processing positioning device is disclosed. By setting an arc-shaped clamping plate, when the arc-shaped clamping plate is damaged or needs to be replaced, the push plates are pulled simultaneously to both sides. The push plates will drive the sliding rods to move outward. The limit rings squeeze the return springs, and the sliding rods are removed from the limit grooves, so that the first connecting plate can be taken out of the first groove. Release the push plates, and then insert the first connecting plate on the new arc-shaped clamping plate into the first groove. The first connecting plate squeezes the inclined surface of the sliding rod, and the sliding rod moves outward. The limit rings squeeze the return springs. When the first connecting plate is completely inserted, when the sliding rod slides to one side of the limit groove and is no longer stressed, it will be inserted into the limit groove under the action of the return spring, so as to realize the rapid replacement of the arc-shaped clamping plate and improve work efficiency and convenience.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: when the device clamps the tire, the tire is fixed and limited by two upper and lower arc-shaped clamping plates, which makes it inconvenient for the tire to rotate. However, when the tire is being inspected or processed, the tire sometimes needs to rotate to meet the requirements of comprehensive processing or comprehensive inspection of the tire. At the same time, when processing or inspecting the surface and side of the tire, the angle often needs to be changed to meet different processing or inspection needs. Summary of the Utility Model

[0028] In the embodiment of the present application, the implementation principle of a rubber tire clamping and limiting mechanism is as follows: When clamping and limiting a rubber tire, place the tire on the surface of the friction wheel 19.

By adjusting the height and distance of the clamping wheel 15, the device can clamp tires of different sizes, improving the applicable range of the device.

[0029] After the position adjustment of the two clamping wheels 15 is completed, the two clamping wheels 15 and the friction wheel 19 form a positioning clamp on the tire. After the clamping is completed, rotate the small double lead screw 16 to make the two limiting plates 17 approach the side of the tire, and finally make the limiting wheels 18 abut against the surface of the tire, so that the two limiting wheels 18 can be adapted to the width of the tire. When detecting or processing the tire, start the motor 20, and the motor 20 will drive the friction wheel 19 to rotate. Under the action of friction, the tire rotates, so as to realize the comprehensive processing of the tire surface.

[0030] When it is necessary to detect or process the side or other positions of the tire, start the cylinder 2, so that the cylinder 2 pushes the slider 3 to move along the slide rail 4, so that the abutting rod 5 drives the rotating frame 6 to rotate, and then the rotating rod 7 drives the rotating plate 9 to rotate through the rotating column 8, so that the angle of the tire on the device deflects, meeting the detection or processing of the tire at different angles and improving the applicable range of the device.
