A vacuum tire air tightness detection device

Abstract

The present invention discloses a vacuum tire air tightness detection device, including a gantry support, a transverse support, a support plate, a clamping plate, and a clamping drive device. The two ends of the transverse support are respectively fixedly connected to the vertical beams on both sides of the gantry support. The support plate is arranged upwardly on the upper part of the transverse support. The bottom or side of the support plate is provided with an air supply hole connected to the top and connected to the air supply pipe of the high-pressure air supply system. The clamping drive device is fixedly arranged on the cross beam of the gantry support on the upper part of the support plate, and the driving rod points downward to the clamping plate. The bottom of the clamping plate is fixedly connected or hinged to the driving rod of the clamping drive device, and the clamping plate is coaxial with the support plate. The present invention drives the clamping plate to move through the clamping drive device, so that the inner cavity of the tire forms a closed space under the clamping of the clamping plate and the support plate, and compressed air is filled to detect whether there are cracks or nail holes on the surface of the tire that cause air leakage. The present invention has the characteristics of simple structure, safety and convenience, high detection accuracy and efficiency, and low labor intensity.
