Abstract: The present invention discloses a rotary wheel airtightness detecting machine which comprises a body frame, an air cylinder, an upper seal, a lower seal, a water tank, an electric motor and a self-made air cylinder, etc. During use, the present invention can make the wheel be automatically centered between the upper seal and the lower seal, avoiding severe abrasion of equipment caused by inclination of the upper pressing plate for sealing upon biased positioning of the wheel.

Abstract: The present invention discloses an apparatus for on-line deburring wheel blank, which comprises a body frame, cylinders, rails, slidable tables, electric motors and cutting systems, etc. When the wheel blank on a conveyor belt is transported to the central location between left clamping blocks and right clamping blocks, the blank is stopped by sensor(s) and lifted by a lifting cylinder via a bracket. Through a gear and two racks, a clamping cylinder drives the left slidable table and the right slidable table to synchronously clamp the wheel blank. A first electric motor drives the clamped wheel blank to rotate in counterclockwise direction. A first feeding cylinder feeds the right lathe tool to make it contact the wheel rim. The function of removing burrs on the wheel rim, which are caused upon closing molds, is realized by the relative movement between the wheel and the lathe tool.
