Embodiment Construction

[0024] Embodiments of the present application relate to a control cage assembly configured to be permanently directed by the manufacturer's settings to the correct shot pattern (also referred to as a "hot spot") through the control cage. The control cage assembly is further configured to prevent incorrect shot pattern placement through the control cage which is presently possible in existing control cage designs.

[0025] The control cage assembly further prevents sub-par blast performance due to user error setting of the control cage / hot spot. This is accomplished by providing color-coded reference points at specific areas that are machined or recessed on the control cage adapter plate where the indicator is attached to (or machined into) the locking ring. The assembly includes an outer control cage retaining ring secured to the control cage adapter plate, on which the control cage is secured to the control cage locking ring. The locking ring is free to float between the ret...

Abstract

A centrifugal blast wheel machine includes a wheel assembly, an impeller positioned about an axis of the wheel assembly, a motor coupled to the impeller to drive the rotation of the impeller and the wheel assembly, and a control cage assembly surrounding the impeller and secured to the wheel assembly. The control cage assembly includes a control cage and a locking ring secured to a peripheral edge of the cylindrical wall. The locking ring includes an indicator projecting radially outwardly from the locking ring, and an adaptor plate secured to the wheel assembly. The adaptor plate includes at least one recess formed therein to receive the indicator when securing the locking ring and the control cage to the adaptor plate. The adaptor plate further includes a retaining ring secured to the adaptor plate to firmly secure the locking ring and the control cage in place.

Description

[0001] Background of the invention [0002] 1. Background of the invention [0003] The present invention relates generally to abrasive shot blasting machines and methods for cleaning or treating workpiece surfaces, and more particularly to control cage assemblies for centrifugal shot blasting machines and methods of assembling centrifugal shot blasting machines. [0004] 2. Background technology [0005] Centrifugal shot blasting machines generally comprise a rotating wheel having a plate or a pair of spaced plates carrying radially extending blades. Particulate matter is thrown from the center of the blast machine onto the rotating surfaces of the blades, which throw the particulate matter onto the workpiece to be cleaned or treated. Specifically, the shot blasting medium is fed from the feed port to the rotating impeller impeller located in the control cage at the center of the shot blasting machine. The media is fed from the impeller mover through openings on the control ...
