Abstract
The tool attachment for converting rotating into reciprocating motion comprises a hollow traveling body having a radial bore and an axial bore therein. A bearing housing is removably mounted in the radial bore. A ram is movably mounted in the bore's axial bore. The ram has on its outer periphery a single closed groove having a pitch depending on the desired reciprocating stroke of the ram. A roller is rotatably mounted in the bearing housing and has a portion thereof disposed in the groove. Restraining means couple the ram to the machine whereby the ram is restrained against rotation and unrestrained against longitudinal motion upon the rotation of the traveling body by a rotatable member of a machine fixedly coupled to the body.
Claims6
A tool attachment for a machine having a rotatable member, said tool converting rotating into reciprocating motion, comprising:
- a hollow traveling body having a radial bore and an axial bore therein;
- a bearing housing mounted in said radial bore,
- a ram movably mounted in said axial bore and having on its periphery a single groove, the groove having a pitch depending on the desired reciprocating stroke of the ram;
- a roller rotatably mounted in said bearing housing and having a portion thereof rollably disposed in said groove, and
- restraining means coupled between said ram and said machine, whereby, in use said ram remains restrained against rotation and unrestrained against longitudinal motion, upon rotation of said traveling body in either direction, and said roller imparts a reciprocating motion to said ram about its longitudinal axis.
