Adjustable Stroke Device With Cam
First Claim
1. An adjustable stroke mechanism for a random orbital machine comprising:
- a housing having a central axis and a wall enclosing a cavity;
at least one counterweight movably disposed within the cavity;
a mounting assembly disposed within the cavity, the mounting assembly including a workpiece attachment mechanism;
a stroke adjustor coupling the at least one counterweight with the mounting assembly, the stroke adjustor enabling the counterweight and mounting assembly to move with respect to one another such that a distance between the counterweight and the mounting assembly is variably adjusted which, in turn, variably adjusts a stroke radius of the workpiece attachment mechanism with respect to the central axis of the housing.

Abstract
An adjustable stroke mechanism has a housing with a central axis and a wall enclosing a cavity. At least one counterweight is movably disposed within the cavity. A mounting assembly is disposed within the cavity. The mounting assembly has a workpiece attachment mechanism. A stroke adjustor couples the at least one counterweight with the mounting assembly. The stroke adjustor enables the counterweight and mounting assembly to move with respect to one another such that a distance between the counterweight and the mounting assembly is variably adjusted which, in turn, variably adjusts a stroke radius of the workpiece attachment mechanism with respect to the central axis of the housing.

9. A method of adjusting a stroke of a random orbital machine comprising:
-
coupling an adjustable stroke mechanism to a random orbital machine, the adjustable stroke mechanism comprising; a housing having a central axis and a wall enclosing a cavity; at least one counterweight movably disposed within the housing; a backing plate mount assembly disposed within the housing;
the backing plate mount assembly including a mechanism for attaching to a workpiece;a stroke adjustor coupling the at least one counterweight with the mounting assembly; adjusting the stroke adjustor; moving the counterweight and mounting assembly with respect to one another; variably adjusting a distance between the counterweight and the mounting assembly; and variably adjusting a stroke radius of the mechanism to attach the workpiece with respect to the central axis of the housing.
