摘要： A device for resurfacing the valve face of a poppet valve in which the pressure between a cutting surface and the valve face is controllable by the operator during the surfacing operation. A bearing case is rotatably attached to a base which is attached to a pair of gripping blocks. A cutting head is rotatably mounted on the bearing case. The cutting head, the bearing case, the base and the gripping blocks define a passage into which a valve stem is inserted. The gripping blocks are clamped in a vise which in turn clamps the valve stem in the device. When the bearing case is rotated, pressure between the cutting surface and the valve face is increased. When the cutting head is rotated, the valve face is resurfaced.

摘要： A valve refacing tool having a housing with a bore therethrough which includes a large-diameter portion at one end thereof. A substantially cylindrical support is disposed within the large-diameter portion of the bore and is removably fixed to the housing, as by a plurality of screws extending radially therebetween. This cylindrical support has a small-diameter cylindrical opening which extends axially from the inner end thereof, and which communicates with the small-diameter end of a truncated conical recess which opens outwardly through the other axial end thereof. This conical recess accommodates the head of a poppet valve. A plurality of cutting blades are secured in angularly spaced relationship around the conical recess. The cylindrical support is split into a plurality of separable arcuate sectors, and each is individually fixedly but releasably secured to the housing. The cylindrical support defines a conical recess having a first angle suitable for refacing valve seats of that angle, but the cylindrical support can be replaced by a second cylindrical support having a different conical angle for refacing valve seats having this latter angle.
摘要翻译：一种具有壳体的阀门换向工具，该壳体具有穿过其中的孔，其在其一端包括大直径部分。基本上圆柱形的支撑件设置在孔的大直径部分内，并且通过在其之间径向延伸的多个螺钉可移除地固定到壳体。该圆柱形支撑件具有从其内端轴向延伸的小直径的圆柱形开口，并且与通过其另一个轴向端向外开口的截头圆锥凹槽的小直径端连通。该锥形凹槽容纳提升阀的头部。多个切割刀片围绕锥形凹槽以角度间隔的关系固定。圆柱形支撑件被分成多个可分离的弓形扇形部分，并且每个分别固定地但可释放地固定到壳体。圆柱形支撑件限定了具有第一角度的锥形凹槽，该第一角度适于重新设置该角度的阀座，但是圆柱形支撑件可以被具有不同锥角的第二圆柱形支撑件代替，以便用于替换具有后一角度的阀座。

摘要： 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.

摘要： A grinding machine particularly for grinding the teeth on a carbide cutter. The machine includes a carriage swingably mounted on a frame for oscillation about a pivot axis. The carriage has a grinding wheel mounted thereon and rotatably driven by a motor which is also mounted on the carriage. The wheel is rotatable about an axis which is approximately parallel to but spaced from the pivot axis. A feeding mechanism projects outwardly from the front face of the grinding wheel at an angle of approximately 45.degree. relative to the rotational axis. The feeding mechanism releasably supports a carbide element. The feeding mechanism is linearly advanced toward the grinding wheel in an intermittent steplike movement which is synchronized with the oscillating movement of the carriage so that the grinding wheel cuts a groove across the carbide element during both the forward and return swings of the carriage. The grooves cut in the carbide element form cutting teeth therebetween, which teeth have a rounded convex configuration due to the engagement of the carbide element with the grinding wheel at a location between the pivot and rotational axes.
