摘要:
This tool holder notably for turret lathes is of the multiple block type and permits modification of the geometry of the tool holder body according to the number of chisels or other tools required for a given machining operation. It comprises a carrier block having a integral shank for securing same to the turret and at least one additional block detachably secured to said carrier block.

A tool holder assembly comprises a support member connectable to a machine tool and having therein a linear slideway. A slide member is slideably mounted in the slideway and the slide member is provided with a tool-holding recess for releaseably holding a work tool. An adjustment device coacts with the support member and the slide member for selectively adjusting the position of the slide member along the slideway to thereby accordingly effect adjustment of the work tool. The adjustment device comprises a screw mounted on the support member for rotational movement but not translational movement and the screw has a threaded portion which extends through a cavity provided in the support member. The slide member is provided with a threaded nut which extends into the cavity and in threaded engagement with the screw so that angular displacement of the screw effects linear displacement of the slide member along the slideway. A manually graspable knob is connected to the screw to enable manual adjustment of the slide member.

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.
