Embodiment Construction

[0042] Fig. 1 shows a tool clamp of the shrinking chuck type, which is usually an integral clamp body 3, which has a sleeve-shaped tool mounting section 5 at one end of the clamp body 3 in the axial direction, which is used to rotate around a rotation axis 7 Ground-driven tools 9, such as milling cutters or drills, and at the axially opposite ends there is a joint section 11 here in the form of a hollow rod joint for resistance to the rotary drive shaft of the machine tool not shown in detail here. Twisted joints. The mounting section 5 has a mounting hole 13 concentric with the axis of rotation 7, which can be thermally expanded by means of an induction coil, especially by induction heating, so the tool 9 can be loosely inserted into the mounting hole 13 or taken out of the mounting hole with its handle 15. After the installation section 5 is cooled, the tool handle 15 is press-fitted and fixed.

[0043] There are a plurality of extensions in the tool 9, where two axial channels ...

Abstract

The aim of the invention is to improve the guiding of a lubricant through a tool holder in a small quantity lubrication system. According to the invention, a tool holder (1) comprises, in the maintaining body thereof (3), an axially displaceable stop sleeve (45) which is mounted in a through opening (31) which is connected to the receiving opening (13) for a tool shaft (15) and a stop surface (47) which is adjacent to the front end (23) of the tool shaft (15). Said stop sleeve (45) is screwed into an inner thread (43) of the through opening (31) and is coupled in a rotationally fixed manner, but in an axially displaceable manner, to a control tube (49) which engages in said stop sleeve (45) in an axial manner. Said control tube (49) is mounted in an axially fixed manner to the side thereof, but in a rotatable manner to the fluid coupling (27). A lubricant can be guided over the blades of the tool (9) by means of the fluid coupling (27), the control tube (49), the stop sleeve (45) and channels (17). Said tool holder (1 ) enables the fluid to be guided in an essentially calm manner to the tool, even in small amounts, and simplifies the longitudinal pre-adjustment of the tool unit / tool holder unit.

Description

Technical field [0001] The present invention relates to a tool holder, in particular to a tool holder for a tool to be rotatably driven around a rotation axis. The tool handle includes at least one channel for cooling and / or lubricating fluid extending along the rotation axis, or with The tool holders together form the boundary of the cross section of their passage. Background technique [0002] It is known that for cooling or lubricant that should be supplied to the cutting edge of a rotating cutting tool (tool), such as a drill or milling cutter, in the form of a liquid jet or as a spray, it is introduced from the drive shaft of the machine tool into the central channel of the tool holder, and From there, the cutting edge is fed through one or more axial holes of the tool (DE10312743A1). It is also known that some axial grooves are provided on the inner circumference of the tool holder mounting hole of the press-fit mounting tool handle for cooling or lubricating fluid (EP06622...
