摘要:
A tool holder, designed to be easily mounted, centered and accurately positioned on a moving head stock type screw machine, including two parallel attaching pins fastened to a tool rest and aligned with two holes on the body of the holder. One attaching pin is held in its hole by a locking pin adjusted by an eccentric camshaft. The other attaching pin is held in place by two adjustable bolts.

A toolholder operating bar is pivotally mounted on a machine base and has a swinging end at which an adjustment device is mounted for pivoting the operating bar in opposite angular directions. A driving connection between the operating bar and toolholder is provided by a drive pin fixed to the operating bar between its swinging end and pivot connection to the machine base. The operating bar drive pin to the toolholder overlies cooperating guide means provided by the toolholder and machine base to constrain the toolholder for solely rectilinear movement in a selected direction laterally of an adjustment axis of the toolholder responsive to actuation of the operating bar.

A tool holder assembly comprises a tool support having a toolholding recess for releaseably holding a work tool and a mounting shank slideably disposed within a bore provided in a machine tool so that the work tool position may be adjusted by adjustably sliding the mounting shank relative to the machine tool. An adjustment device connected between the tool support and the machine tool enables very accurate adjustment of the work tool position. The adjustment device comprises an externally threaded tubular shaft connected to the machine tool and slideably receiving therethrough the mounting shank, and an internally threaded hollow sleeve rotatably connected to the tool support and threaded onto the tubular shaft. The hollow sleeve is rotatably connected to a support flange affixed to the tool support by means of a set of antifriction rollable members housed in bearing races formed directly in the support flange and the hollow sleeve. A series of blind holes are provided around the outer surface of the hollow sleeve and a tool inserted into the blind holes enables manual rotation of the hollow sleeve to effect axial displacement of the tool support and thus the work tool relative to the machine tool.

A tool holder for machine tools, such as automatic lathes, includes a body for attachment to the turret of the lathe. A tool support is connected to the body and adjusting means is attached to the tool support for adjusting the position of the tool support relative to the body. The adjusting means includes two relatively rotatable parts and roller means between the parts.

Machine tool apparatus including workpiece supporting means for supporting and rotating a workpiece, and a tool holder movable in parallel and transverse directions with respect to the rotary axis of the workpiece supporting means. A cutting or grinding tool is mounted on the tool holder for selective rotation about a tool axis, the tool having a workpiece engaging portion located on the tool axis so that the tool can extend perpendicularly to the surface of a workpiece regardless of the contour of the workpiece as the tool holder moves the tool along the length of the workpiece.
摘要:
A holder for a cutting tool for processing of workpieces has a first part for holding a cutting tool (150), a second part (120) to which the first part is fastened, and a fastening element (140). An adjustment element adjusts the position of the first part in relation to the second part. The first and second parts have a first bore and a second bore for receiving the fastening element and a recess (118, 128) for receiving the adjustment element. The first part has an abutment surface (115) placed onto a contact surface (122) of the second part, such that the central axes (A-A) for the first and second bores become parallel. The abutment surface of the first part and the contact surface of the second part are inclined in relation to the feeding axis (G-G) of the work piece towards the cutting tool (150).
