Description

Technical Field

[0001] The utility model relates to the technical field of tire correction, and particularly relates to a horizontal tire expanding and centering device. Background Art

[0002] Tire eccentricity means that the steel rims on both sides of the tire are not concentric. Most non-concentric tires are treated as waste products, which seriously wastes resources. Solving the eccentricity of the tire steel rim only requires using a tire centering device.

[0003] Existing tire expanding devices are mostly independent devices. The tire is vertically sleeved on it, and manual tire loading is required. The operation is complex, and the expansion stroke range is limited. It is difficult to expand the inner diameter specification of the tire and it is difficult to achieve automation. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model discloses a horizontal tire expanding and centering device.

[0005] A horizontal tire expanding and centering device includes an upper tire expanding device installed on the upper part of the frame and a lower tire expanding device installed on the lower part of the frame. The upper tire expanding device and the lower tire expanding device are symmetrically arranged; both the upper tire expanding device and the lower tire expanding device include a tire expanding lifting device and an openable tire expanding support device. The upper tire expanding device and the lower tire expanding device move up and down to the inner side of the tire bead of a horizontally placed tire, and support the upper and lower edges of the tire bead through the tire expanding support device, so that the centers of the steel rims on both sides of the tire are concentric.

[0006] Further, the tire expanding lifting device includes a tire expanding lifting servo motor, a lifting guide rail, and a lifting frame. The tire expanding lifting servo motor is installed at the end of the lifting guide rail. One end of the lifting frame is clamped in the lifting guide rail, and the other end of the lifting frame is connected to the tire expanding support device.

[0007] Further, the tire expanding support device includes a tire expanding support servo motor, a tire expanding guide shaft, a guide disk, and a tire expanding bracket. The tire expanding support servo motor is connected to the tire expanding guide shaft through a tire expanding support electric cylinder. A tire expanding guide sleeve is slidably sleeved outside the tire expanding guide shaft. The tire expanding guide sleeve is fixedly connected to the guide disk. The guide disk is slidably connected to the tire expanding bracket through a linear guide rail.

[0008] Further, at least two linear guide rails are radially opened on the guide disk from the axis to the outside, and a tire expanding bracket is clamped on each linear guide rail.

[0009] Furthermore, there are at least two tire expanding brackets, and hexagonal shafts are respectively hinged to the bases of the opposite tire expanding brackets;

[0010] A connecting frame is arranged at the end of the guide shaft, and the hexagonal shafts are respectively hinged to both sides of the connecting frame;

[0011] The connecting frame ascends and descends, driving the tire expanding bracket to slide along the linear guide through a hexagonal shaft, so that the tire expanding bracket supports the edge of the bead.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The tire enters the working station in a horizontal manner. The upper tire expanding device and the lower tire expanding device move up and down to the inside of the tire bead of the horizontally placed tire through the tire expanding lifting device. Through the expansion and contraction of the tire expanding device for tires of different sizes, the centers of the steel rims on both sides of the tire are kept concentric. At the same time, through the spacing control of the tire expanding device, the stable support of the upper and lower edges of the bead is ensured by maintaining the stable distance between the tire bead openings. The upper tire expanding device and the lower tire expanding device act in the opposite direction to release the tire.

[0014] The tire is placed horizontally. On the one hand, it is convenient for loading and unloading the tire. On the other hand, it is also convenient to quickly position the tire through the positioning mechanism, and it is not limited by the tire size and can adapt to the positioning of tires of various sizes.
