| 21 | Tool and method for the cutting machining of a workpiece | US09470218 | 1999-12-22 | US06345937B1 | 2002-02-12 | Dieter Kress; Herbert Jäger |
| A tool for cutting machining a workpiece, including a cutter plate supported on a holder for machining a surface and additionally comprising a tool projecting from the body of the tool. The cutter plate is supported on a holder which is in turn supported on a rotatable eccentric such that rotation of the eccentric moves the holder radially. A cooperating converting device converts axial movement of an actuating device into rotation of the eccentric through intermeshing gear elements. A second tool, e.g., a reamer, is moved by a second push/pull rod axially with respect to the body of the tool and into the workpiece, and the second tool is supported on the axis of the main body. | ||||||

| The invention relates to a position drive for a tool head for use in machine tools. The tool head comprises a base body (12), a tool shank (16) which protrudes axially over the base body (12) and is coupleable to a rotating machine spindle (14), and a thrust member (18) which is movable with respect to the base body (12) and which serves to move at least one tip holder or cutting tool (76). Further, an electric motor arrangement (24), which is coupleable to the thrust member (18), and a power supply device (26) for the motor arrangement (24) are positioned on the base body (12). In order to ensure a compact construction having an efficient motor arrangement, a hollow shaft (50) is borne rotatable about an axis of the base body (12), which is concentric with respect to a displacement axis (52) of the thrust member (18), and the hollow shaft (50) has an internal thread which engages in an external thread (42) of the thrust member (18). The hollow shaft (50) has a toothed ring (62) which is positioned concentric with respect to the external thread (42), for the engagement of at least one gear (70) which is positioned on a driven shaft (68) of the motor arrangement (24). | ||||||

| A cutting tool has a slidable cutting-blade chip 5A, in which a slider 7 is slidably mounted into a groove 6 formed in the cutting tool main body 1, to offset a pressing force applied to the bottom face 6c of the groove 6 through the slider 7, to prevent abrasion of the slider 7 and the groove 6 and uneven abrasion of serration grooves 7a and 8a of the slider 7 and a spacer 8, and to suppress backlash of the slider 7. A spacer 9 is detachably disposed between one side face 6a of a groove 6 and a slider 7, a plate 22 is disposed between another side face of the slider 7 and another side face 6b of the groove 6 so as to press the plate 22 toward the side face 6a. A protruding section 21 and a dent section 24 each have a V-shape cross-section and are formed on another side face of the slider 7 and on one side face of the plate 22, respectively, wherein the protruding section 21 and the dent section can come into contact with each other. | ||||||

| A method and machine for machining the surface of a valve seat (3) which is required to have a very accurate alignment with respect to a guide bore of a valve guide (2).In order to be capable of machining the valve seat surface in high roundness while maintaining a high concentricity with the guide bore, a pilot member (4) is moved forward inclinably to catch a guide bore of a valve guide (2) at its front end; the pilot member is further moved forward bendably while following the guide bore; when the pilot member has reached the desired position, the posture of the pilot member in the position is firmly held; and the surface of the valve seat (3) is machined by moving edged tool members (5a) forwardly while rotating the edged tool members (5a) which are arranged coaxially with the pilot member. A machine for practicing the method includes a forwardly and backwardly movable spindle (8), a pilot member (4) bendable at (7) with respect to the spindle, a bearing member (15) for the pilot member provided alignably with respect to the pilot member, an arrangement (17) for holding the bearing member coaxially with the pilot member, and edged tool members (5a) arranged to be rotatable coaxially with the pilot member and movable forwardly and backwardly together with the pilot member. | ||||||
| 29 | Valve guide boring fixture | US3764204D | 1971-11-19 | US3764204A | 1973-10-09 | KAMMERAAD J |
| A portable, U-shaped valve guide boring fixture to be mounted on and supported by a cylinder head for an internal combustion engine in order to guide the reworking of the valve guides in said internal combustion engine. The fixture comprises a support post on which are mounted two guide arms normal to the axis of said post. The second arm is fixedly mounted at one end of the post and includes spring seat engaging means. The first guide arm is slideably mounted and spring biased toward the second guide arm intermediate the ends of said post and includes valve seat engaging means comprising a pivotally mounted ball swivel guide having an axial bore to guide said reworking operation. The fixture is clamped over the spring seat and valve seat on the cylinder head, and a tapered alignment pin is inserted through said engaging means and said valve guide to bring the fixture into axial alignment with the valve guide by means of the pivotal action of the ball swivel guide. The fixture is then tightened into said aligned position and may be used to guide the boring and reaming operations, accomplished by means of hand tools, resulting in a reworked valve guide in accurate axial alignment with said valve seat.
