摘要： The valve seat and guide machine comprises a base structure on which is pivotally supported a pantograph having a major arm (112) on which is mounted a drive motor (138) and minor arm (110) which moves slidably with respect to the major arm. Pivotally attached to each arm of the pantograph is a head portion (118) with a support frame (118) which retains a spherical head (140) and a plurality of sphere seats (142, 144) for supporting the spherical head (140) so that it can pivot around its centerpoint at the center of the sphere. A stepper motor (152) is disposed at the top of the spherical head and a spindle (150) disposed with the spherical head (140) retains a cutting bit (156) and a pilot (158) which extend from the bottom of the spherical head. Small z-axis displacement and spindle feed/retraction along the z-(vertical) axis is provided by the stepper motor (152). The drive motor (138) rotates a transmission linkage which, in turn, rotates the spindle (150) using cone-shaped pinions (318, 320) to cause the cutting bit, typically carbide, to cut the valve seat. Small x, y displacements are enabled by moving the entire spherical housing and its supporting sphere seats with respect to the support frame. The pantograph swings up and down on the base to provide large z-axis displacement to remove the spindle from the cutting position and to provide clearance for movement to another machine site. A system controller (162) receives feedback from system monitors to control spindle rotations and feed/retraction.

摘要： The detached cylinder head is placed on a table or other flat surface which has a recessed area within which is retained a deformable elastic bladder. Air, water or some other fluid is introduced into the bladder causing it to expand so that it conforms to the chambers within the cylinder head. The pressure of the expanded bladder within the chamber forces the valve upward against the valve seat. Once the valve is pressed upward against the valve seat, the valve can be disassembled by depressing the spring and removing the fastener, so that the spring can be removed, or the spring can be put in place and the valve reconnected.

摘要： The pulling tool has a pulling head for gripping an insert, such as an engine valve seat or a pre-combustion chamber, and for pulling it out of a recess. A gripping mechanism for an annular insert, such as a valve seat, may grip the insert by its inner edges. Such a gripping mechanism includes a shaft (8) that slides freely through a bore (10) in the body in a direction parallel to the body. At the end of the shaft (8) is a cone (13) which cooperates with at least two toothed claws (16, 16'). The toothed claws (16, 16') may be pivotally mounted on a lower extension of the body or may be integrally formed with one another as a collet and flex radially outwardly. The body may have a lever (12) that, when depressed, lifts the shaft (8), pulling up on the cone (13), causing the claws (16, 16') to move outward, and causing teeth to penetrate the metal of the insert on its inner diameter to lock into the insert. A gripping mechanism for an insert having a central or eccentric opening, such as a pre-combustion chamber, may have a pivoting claw arm with a tooth on one end. The end of the arm with the tooth is inserted into the opening of the insert at an oblique angle. A set screw forces the claw arm to pivot, which causes the tooth to penetrate the metal of the insert from behind. A pneumatic puller (18) may be used with either gripping mechanism to remove the gripped insert from the recess.

摘要： On place la culasse démontée sur un établi ou une autre surface plane dotée d'une zone creuse dans laquelle est retenue une vessie élastique déformable. On introduit de l'air, de l'eau ou un autre fluide pour gonfler cette vessie et lui faire épouser le contour des chambres situées dans la culasse. La pression de cette vessie gonflée dans la chambre repousse la soupage vers le haut contre le siège de soupape, ce qui permet alors de la démonter, en détendant le ressort et en libérant l'attache afin de retirer ce ressort. Inversement, on peut remettre le ressort en place et remonter la soupape.

摘要： A spindle (24) with a self-centering grip, or collet (30), and one or more pilots (26) that the grip (30) may engage. The grip (30) has radially expandable and contractable portions (32) for engaging a pilot (26) between them. The pilot (26) is inherently centered in the spindle (24) because the gripping forces are equally distributed around the pilot. Each pilot (26) consists of two adjacent, coaxial cylindrical guide portions (34, 42) of different diameters. A set of such pilots can be provided where each guide portion of each pilot has a diameter that is different from that of every other guide portion of the pilots in the set. The guide portion diameters may correspond to the diameters of the valve guides (20) of particular engines or may increase incrementally over a predetermined range. A pilot (26) can thus be selected from the set to fit the valve guides (20) of a particular engine.

摘要： The single point machining head (10) includes a probe (601) that is removably mounted on a carriage (30) that moves radially relative to a central axis of the machining head. A system controller moves the carriage in a radial direction while the machining head is fed in a vertical direction so that the probe contacts the surface of a workpiece. Each point of contact on the workpiece becomes a datapoint including the radial position and the vertical position when contact occurred.

摘要： A method and machine for repairing overhead cam engine cylinder heads and the like. The method includes the steps of removing the caps from the bases of the bearing towers or housings, removing material from the legs of the caps to reduce their height, replacing the caps on the bases, and boring the resulting bearings to produce bearings of the proper diameter. The machine includes a device for machining a bearing cap and a device for boring the bearings. The device for boring the bearings has a boring bar that is supported only at opposite ends of the cylinder head. The bar does not sag or chatter because it is made of an extremely hard and dense material such as a dense tungsten alloy or a ceramic-coated metal.
