Rotating Bore Sprayer Alignment Indicator Assembly

摘要

An alignment assembly for a rotating thermal sprayer may include an elongated alignment base that connects at one end to a sprayer positioning assembly connection mechanism, and an indicator device disposed at the opposite end of the alignment base and rotating about a sprayer rotational axis defined by the sprayer positioning assembly. The indicator device may have a visual indicator operatively connected to a stylus so that a display of the visual indicator changes when the stylus moves relative to a stylus neutral position. The sprayer positioning assembly may position the stylus in contact with a concave surface that will be coated, such as an engine bore, and the indicator device rotated about the sprayer rotational axis to determine whether display of the visual indicator changes to indicate if the sprayer rotational axis is aligned with a longitudinal axis of the concave surface.

1. A sprayer alignment assembly for aligning a sprayer rotational axis of a rotating sprayer with a bore longitudinal axis of a concave surface, wherein the rotating sprayer mounts on a sprayer positioning assembly that moves the rotating sprayer relative to the concave surface, the sprayer alignment assembly comprising:
an elongated alignment base having a first end and an oppositely disposed second end; an alignment base connection mechanism disposed at the first end of the elongated alignment base and configured to engage a sprayer positioning assembly connection mechanism and align an alignment base longitudinal axis along the sprayer rotational axis defined by the sprayer positioning assembly; and an indicator device disposed at the second end of the elongated alignment base and rotating about the sprayer rotational axis when the elongated alignment base is attached to the sprayer positioning assembly, wherein the indicator device has a visual indicator and a stylus operatively connected to the visual indicator such that a display of the visual indicator changes when the stylus moves relative to a stylus neutral position.
