Description

Universal tire testing machine Technical Field The utility model belongs to the technical field of automobile repair equipment, and particularly relates to a universal tire testing machine. Background In the conventional tire repairing device, a tire is usually fixed on a rotatable device, and a leakage point is searched by observing the tire with naked eyes or spraying soapy water on the tire while rotating the tire, so that if the leakage point of the tire is hidden or the leakage point of the tire is small, the leakage point is not easy to confirm by the method. Through technical innovation, a tire air testing machine is designed by a person skilled in the art, as disclosed in publication No. CN218822979U, a frame body is provided with two side rotating sleeves which are horizontally and correspondingly arranged on the left and right sides for clamping and assembling and sealing a tire, an air supply pipe is arranged on one side of the rotating sleeves for supplying air to the inside of the tire, and a liftable water tank is arranged at the lower part of the rotating sleeve. The tyre is fixed between the two rotary sleeves and inflated by air, the tyre is soaked by the lifting water tank, and the air leakage position of the tyre can be seen by naked eyes when the tyre is rotated. The utility model has simple structural design and convenient use, and can quickly realize the checking of the tire leakage points. However, the above-mentioned equipment has the following new technical problems when in actual use, 1. The water tank is fixed in the middle, because the water tank is filled with liquid, the weight is large and the water tank is unstable when moving vertically, 2. The existing equipment uses the bearing component to rotate in the axial rotating part when in use, but has the air leakage phenomenon when in high-pressure supply, which affects the checking effect of the air leakage point, 3. The existing equipment can only detect the tires with the same model, and the application range is narrow, which is not beneficial to commercial popularization. Aiming at the defects in the prior art, the technical problem to be solved in the prior art is how to design a tire repairing machine capable of realizing the detection of multiple types of tires, which can avoid the technical problems of air leakage, pressure relief and the like in the detection. Disclosure of Invention In order to overcome the defects of the prior art, the utility model provides a general tire testing machine which is novel in structural design, detection sealing is realized by sealing a tire rotating device, and the tire with various types is correspondingly realized by adopting a replaceable component, so that one machine can be multipurpose, and the equipment use efficiency is improved. The universal tire testing machine comprises a support body capable of achieving support, two rotating sleeves are horizontally and coaxially arranged on the support body, a multi-position hub is arranged on the rotating sleeve, at least one side of the multi-position hub can transversely move left and right to achieve tire clamping, an air supply pipe is arranged on the multi-position hub on at least one side of the multi-position hub to supply air to the inside of a tire, a liftable water tank is arranged on the lower portion of the rotating sleeve, a vertical guide groove is arranged on the side wall of an upright post of the support body, the vertical guide groove is matched with a sliding block on the water tank, a lifting driving device is arranged on the lower portion of the water tank, and vertical lifting of the water tank is driven by the lifting driving device.
