Abstract
Presented is a work rest blade assembly for a centerless grinder that provides multiple wear surfaces on which a work piece may be supported. The work rest blade assembly includes a generally cylindrical work rest bar splined at opposite ends and clamped to a crowned support plate in such a manner that the bar is flexed from end to end to impose a bending moment thereon and is twisted in opposite directions at opposite ends so as to impose a rotary moment on the bar to thus rigidify it.
Claims13
A work rest assembly for centerless grinders comprising:
- a. a generally elongated flat body including an elongated edge having a crown therein;
- b. a work rest blade supported on the crowned edge of the body;
- and
- c. clamp means at opposite ends of the elongated body engaging the work rest blade to simultaneously clamp the work rest blade to the crowned edge of the support body and impose torque on said work rest blade.
A support plate for a work rest blade for use in conjunction with a centerless grinder, comprising;
- a. an elongated generally flat support plate having a pair of apertures adjacent opposite ends thereof;
- b. metal dowels supported in said plate and extending across said apertures from opposite ends of said support plate, said dowels being in axial alignment and spaced in substantial parallel relationship to one long edge of said support plate;
- c. means formed in said one long edge of said plate adapted to receive a work rest blade thereon;
- and
- d. means pivotally secured to said elongated plate and including portions projecting past said one long edge of said plate and adapted to engage a work rest blade supported thereon.
A work rest blade for use in conjunction with a centerless grinder comprising:
- a. an elongated generally cylindrical body symmetrical about a longitudinal axis and having uniform diameter opposite end portions;
- b. the end portions at opposite ends of said elongated body having elongated splines formed therein defining elongated grooves about the circumferential periphery of said end portions, the number of splines on one end portion of said body being equal to the number of splines on the end portion at the opposite end of the body;
- and
- c. one set of splines at one end of the work rest blade being circumferentially offset from the splines at the opposite end of the work rest blade a predetermined amount.
