Abstract
A piston ring grinding apparatus providing piston rings of consistent gap is disclosed. The piston ring grinding apparatus has a base member with a piston ring grinding means mounted thereon. The piston ring holder is rotatably mounted on the base member for movement of a piston ring mounted thereon into and out of contact with the grinding means. A gauge means are in operative association with the piston ring holder and are mounted on the base member in a position to gauge rotational movement of the piston ring holder.
Claims22
A piston ring grinding apparatus comprising:
- a base member having slot means,
- piston ring grinding means mounted on the base member,
- a piston ring holder which is at least rotatably mounted on the base member for movement of a piston ring mounted thereon into and out of contact with the grinding means, and comprising a cup and turntable, and
- gauge means mounted on the base member for gauging rotational movement of the piston ring holder,
- said gauge means being in operable engagement with the piston ring holder, and having means connected to said operable means for indexing a desired amount of material to be removed from the piston ring and for indicating the actual amount of material being removed from the piston ring upon the rotational movement of the piston ring holder,
- said cup being slidable within said base member, and
- said turntable being mountable and rotatable within said cup.
