Abstract
This invention relates to a device useful in making circular shapes of predetermined size on power sanding machines and the like. The device is essentially a fixture which enables a workpiece to be located on an adjustable center so that it can be rotated with respect to a driven sanding disc, polishing wheel, or similar abrasive tools. The device also permits an oversize workpiece to be fed into the sanding disc until the predetermined radius is reached.
Claims4
A fixture for producing circular parts for use in conjunction with an abrasive wheel or the like;
- said fixture consisting essentially of;
- a base including means for positioning said fixture a fixed distance from said abrasive wheel, a pivot pin joining said base and a platen for pivotal movement, said platen having a plurality of work-mounting pin locations with a work-mounting pin positioned in one of said locations for mounting a workpiece center for rotation thereupon, and positive stop means which limits the degree of pivotal movement of the platen with respect to the base.
A work holding fixture to facilitate the production of circular parts on the worktable of a disc sander or the like, said fixture including:
- a. a base having means to position said fixture on said worktable,
- b. a platen, having a plurality of work-mounting pin locations, pivotally mounted to said base for pivotal movement in a plane parallel to said worktable,
- c. a work-mounting pin in one of said locations on said platen and
- d. positive stop means to limit the degree of pivotal movement between said base and platen whereby a workpiece may be mounted on said work-mounting pin, said platen pivoted to the degree permitted by the positive stop means and the workpiece rotated on said work-mounting pin against a tool to produce a circular part.
