US 5,020,284 A · Self-biasing honing tool

Abstract

A honing tool operated by a common motor or a drill while the part being honed is held by a common vice. A spring is positioned within a tubular sleeve member that is aligned with a boss member formed on the trailing end of a conventional housing for a conventional feedup rod. The leading end of the spring bears against the trailing end of the feedup rod and urges it continuously forwardly so that honing continues for as long as the spring is allowed to bear against the feedup rod. The honing operation can be stopped at any time by pulling back on a ring member that causes the spring to be compressed when pulled back. When the spring is compressed, the bias is taken off the feedup rod and hence the cutting stone, so that the diameter of the bore being honed can be measured. In a second embodiment, the final position of the ring member is marked at the conclusion of a honing operation that is to be repeated and a stop member is set so that subsequent honing operations conclude when the ring member attains the final position and is stopped by the stop member.

Dependent claims

In a honing tool having a housing of the type where a tubular boss means is formed on a trailing end of the housing and where the trailing end of a feeding rod is slidably mounted for axial movement within said boss means, means for effecting axial travel of said feedup rod, comprising:

a tubular sleeve member having a leading end fixedly secured in open communication and in axial alignment with a trailing end of said boss means;
a bias means disposed in said sleeve member;
a leading end of said bias means being disposed in abutting relation to the trailing end of said feedup rod;
means external to said honing tool for compressing said bias means so that said bias means exerts pressure on said feedup rod;
a pair of diametrically opposed, longitudinally extending slot members being formed in said sleeve member;
a bore means being formed adjacent the trailing end of said feedup rod;
a linear-in-configuration pin member extending through said slot members and said bore means;
means for retaining said pin member in said slot members and said bore means;
said means for retaining said pin member comprising a feedup ring member of generally toroidal configuration;
said feedup ring member being centrally bored to axially receive said sleeve member;
and
said feedup ring member having a pair of diametrically opposed, radially disposed bore means formed therein to accommodate said pin member.
