Abstract
This utility model relates to a pneumatic centering fixture for diesel engine exhaust aluminum components, comprising a base, an annular positioning seat on the base, at least three radial channels spaced circumferentially on the sidewall of the annular positioning seat, a top block slidably connected within the radial channels, and a pneumatic chuck mounted on the inner ring of the annular positioning seat. The jaws of the pneumatic chuck correspond to the top block and are used to push the inner end of the top block outward so that the outer end of the top block abuts against the inner cavity sidewall of the workpiece. This machining fixture facilitates the centering and positioning of the exhaust aluminum component blank.
