Abstract

PURPOSE:To remove chips adhered to a taper section by air even under a condition that a tool holder is fitted to a main shaft by fitting the tool holder to the main shaft as a part of the taper section of the holder. CONSTITUTION:A tool holder 2 is fitted to a main shaft 1, and a main shaft hole taper section 5 is in contact with a tool holder taper section 6 only at A and B sections. Therefore, when the compressed air is fed through an air discharge port 4, the air flow in the arrow direction through the gap between a main shaft hole taper face and a tool holder taper face, and is discharged outside. Chips adhered on the taper face of the main shaft hole are blown off by means of this air flow, which gives a good cleaning. Recesses and protrusions shown as C, D are provided on the taper section of the tool holder, thus varying the gap of the taper section, thereby the air flow speed is accelerated or decelerated and the cleaning effect can be improved.

Description

【発明の詳細な説明】 この発明は工作機械に川いられる工具ホルダーに関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tool holder that can be installed in a machine tool.

従来、工作機械主軸穴のテーバ部に附着した切粉、塵埃
などの清掃は人為的に行なわれるかもしくは、工具交換

しにより行っていた。Conventionally, chips, dust, etc. adhering to the tapered part of the spindle hole of a machine tool have been cleaned manually or by blowing air out from inside the spindle or end face when changing tools.

特に自動工具交換機能を有する自動工作機械においては

があり、工具の芯出し粘度不良等の原因となっていた。Particularly in automatic machine tools having an automatic tool change function, the large diameter tapered surface is cleaned with compressed air blown from a small diameter nozzle during a short period of time when the tool is changed. For this reason, although its effectiveness is not perfect, there are cases where the tool is received with chips, dust, etc. attached to the spindle hole taper, causing poor centering viscosity of the tool, etc. Ta.

いる工具ホルダーを提供することにある。In view of the above-mentioned problems, this invention makes it possible to exhaust air even when the tool holder spindle is attached, which significantly lengthens the cleaning time, and also provides unevenness on the tool boulder taper section to adjust the air flow velocity. It is an object of the present invention to provide a tool holder for use in a machine tool, which improves the cleaning effect by increasing the effect of blowing off chips and the like by attaching the holder, and which makes it possible to maintain the accuracy of the taper part of the spindle hole.

ある。An embodiment of the present invention in which the tool holder of the present invention is installed in a spindle hole will be described below with reference to the drawings.

第１図は本発明の工具ホルダーを主軸穴に装着した例を
示すものである。FIG. 1 shows an example in which the tool holder of the present invention is installed in a spindle hole.

いる。The tool holder 2 is attached to the main JIl+ 1, and the contact between the spindle hole taper part 5 and the tool boulder taper part 6 is made only at one part of the large diameter part of the tool holder taper and one part B of the small diameter part. The rear and other parts have a gap with the main shaft hole taper.

を行なう。When compressed air is sent into the sealed main spindle 1 at the rear end (not shown) through the air outlet 4 in the tool holder installed state, the air flows from the small diameter end of the taper to the spindle hole taper surface and the tool holder taper. The large diameter end of the taber is discharged out of the machine through the gap between the parts as shown by the arrow in the figure. At this time, the taper portion of the spindle hole is cleaned by blowing away chips, dust, etc. that have adhered thereto.

い。The tool holder according to the present invention, of which the following is an example, mainly has I.
Although there is one point that it can be used while rotating the QIl and is not suitable for high loads, it is very effective when used with a centering tool etc. that originally requires high precision.
