ABSTRACT:
A valve-seat cutting machine having a vertically movable support structure with a vertically elongated spindle assembly mounted thereon. The spindle assembly includes an elongated pilot adapted to be axially inserted into a bore formed in an engine block. A cutting tool is rotatably positioned in surrounding relationship to the pilot rod and is driven from a substantially coaxially aligned driving sleeve, which sleeve is connected to the tool by an intermediate coupling which permits substantially universal movement so that the tool can undergo angular and/or lateral misalignment relative to the rotational axis of the driving sleeve. The pilot rod, which moves angularly or laterally with the cutting tool, is also connected by a similar joint structure to an actuator which permits the pilot rod to be slidably moved relative to the cutting tool. A compression transmitting structure extends through the latter-mentioned joint structure to permit a pushing force to be imposed on the pilot rod. The support structure has a locking plate horizontally slidably mounted thereon, which locking plate has a swivel connection with the cutting tool. When the pilot rod has been inserted into the valve bore and the tool has assumed an aligned position relative thereto, in which position the tool may be angularly and/or laterally misaligned relative to the driving sleeve, then a locking actuator is energized to fixedly hold the locking plate in its adjusted position, thereby holding the cutting tool in its adjusted position during the valve-seat cutting operation.
