Problems solved by technology

This can lead to an undesired enlargement of the nozzle jet and a separation of the components of the medium
Furthermore, the end face groove must be fitted precisely in order to avoid leaks and the wall thickness must be dimensioned sufficiently in order to avoid breakage, which is especially problematic for clamping heads

Embodiment Construction

[0023] The tool head 10 shown in the drawing basically has a shrinking head 12 for clamping a tool shaft 14 of a rotary tool 16 , for example a drill or milling cutter, which rotates about an axis of rotation 15 12 is a nozzle ring 18 which has nozzle openings 20 for impinging the rotary tool 16 with cooling lubricant in the form of a liquid and / or gaseous medium.

[0024] as best by figure 1 and 2 As can be seen, the tool head 10 has a hollow shank cone 22 for docking to a rotating machine spindle. The hollow space 24 of the hollow rod cone 22 is also used for the machine-side supply of cooling lubricant which can be sprayed via the delivery channel system 26 in the constriction head 12 through the nozzle openings 20 of the nozzle ring 18 onto the rotary tool 16 for cooling, lubrication and cleaning of the work area.

[0025] The shrinking head 12 comprises a cylindrically hollow clamping region 28 as a sleeve part, which is opened through a front opening 30 at the front e...

Abstract

The invention relates to a tool holder comprising a chuck (12) which can be rotatably driven about an axis of rotation (15) and has a hollow clamping portion (28), accessible via an end opening (30),for clamping a rotary tool (16), and comprising a nozzle ring (18) which is mounted on the end of the chuck (12) and has nozzle holes (20) for spraying the rotary tool (16) with a liquid and / or gaseous medium. According to the invention it is proposed that the nozzle ring (18) be accommodated in an annular recess (32) in the chuck (12) which expands the end opening (30) in stages, the nozzle ring(18) being fixed in the annular recess (32) by connecting means (34), and having an inner jacket (36) which forms a radial boundary for the insertion of the rotary tool (16).

Description

[0001] This application is a divisional application of the Chinese patent application 201580004431.8 with the filing date of January 15, 2015, entitled "Tool Holder with Nozzle Ring". technical field [0002] The invention relates to a tool holder with a rotatably drivable clamping head, preferably configured as a retracting head, and a nozzle ring arranged laterally on the clamping head on the front side, the clamping head having a through-face opening. The accessible hollow clamping region serves to clamp the tool shaft of the rotary tool, and the nozzle ring has nozzle openings for impinging the rotary tool with a liquid and / or gaseous medium. Background technique [0003] A similar tool holder is known from document US-PS 7 785 046 . There, a ring insert provided with a nozzle ring is proposed, which is inserted into an end-face groove of a tool holder with radial clamping bolts. The distance from the tool shaft is achieved by the inner side wall of the front groove, wh...
