Abstract
A rotary cylinder hone includes an elongate drive shank connected to a carrier arm holder which supports a plurality of arm assemblies having abrasive units carried at the ends thereof. Each arm assembly has a pair of flanges formed at the end opposite the abrasive unit and a projection of the carrier arm holder is receivable therebetween. The flanges have apertures formed therein for receiving a circular retaining ring. The retaining ring is received by a generally circular slot provided in the carrier arm holder projections and serves to support the arm assemblies to the carrier arm holder for pivotable movement in a plane extending generally radially of the drive shank center line, thereby eliminating the need for individual attachment means for each of the arm assemblies.
Claims5
A cylinder hone comprising in combination
- an elongate drive shank;
- a plurality of arms, each arm having a first free end;
- an abrasive unit carried on said first free end of each arm;
- a second end of each arm terminating with a pair of flanges, said flanges being generally parallel one to another and each being formed with a curvilinear edge defining a cam surface projecting away from said second end;
- a carrier arm holder disposed centrally of said arms and having a central stem extending therefrom connected to said drive shank, said carrier arm holder having a plurality of projections extending radially outwardly from said stem;
- said projections each being received within a pair of flanges provided on a respective arm assembly;
- a collar member having a central aperture through which said stem extends and biased into abutment with said cam surfaces of said flanges;
- an aperture formed in each of said flanges;
- a generally circular retaining ring received within the apertures of said flanges;
- whereby said arms are supported by said retaining ring for pivotable movement in a plane extending generally radially of the centerline of said drive shank.
