The setting of the positioning device 14 enables the tire tooling 1 to position the wheel hub 101, thereby improving the assembly accuracy of the tire blowout emergency safety device, and the method of separating the wheel hub 101 and the tire 102 by the wheel hub support seat 12 can improve the assembly efficiency of the tire blowout emergency safety device. At the same time, the limiting ring limits the tire 102, and the positioning device 14 limits the wheel hub 101, so that the tire tooling 1 presents a form of limiting the tire 102 on one side and limiting the wheel hub 101 on the other side, thereby avoiding excessive compression, deformation and damage of the tire 102, and improving the safety of the tire 102.

[0041] In some embodiments, after the tire blowout emergency safety device is assembled, the wheel hub support seat 12 can also be controlled to descend to drive the wheel hub 101 and the tire 102 to fit together again.

[0042] According to one embodiment of the utility model, the positioning device 14 includes a positioning rod 141 and a positioning block 142. The positioning rod 141 is arranged at the center of the wheel hub support seat 12 and is suitable for passing through the center hole of the wheel hub 101; the positioning block 142 is arranged on the positioning rod 141 and is suitable for cooperating with the center hole on the wheel hub 101 to position the center hole of the wheel hub 101.

[0049] Specifically, the positioning device 14 is further provided with a radial push rod 144, which is arranged on the wheel hub support seat 12 and is movable in the radial direction. The movable here can be understood as the radial outer end of the radial push rod 144 can be extended and retracted in the radial direction. The radial outer end of the radial push rod 144 is provided with a limiting portion 145, and the limiting portion 145 can cooperate with the rim 106.
