Description

本発明は、工作機械の工具マガジンに装備されかつ工具を収納するための工具ポットに関する。   The present invention relates to a tool pot mounted on a tool magazine of a machine tool and for storing a tool.

従来、工具ポットの先端面がその全面にわたって平坦状に形成されている工具ポットは知られている。   Conventionally, a tool pot in which a tip surface of a tool pot is formed flat over the entire surface is known.

このような工具ポットに、ＪＩＳ（Ｂ６３３９）規格の工具を装着した場合、工具ポット先端面と工具に設けられたフランジの間には数ｍｍの隙間が生じるようになっている。この隙間に工具抜用レバーを差込み、テコの原理により工具を引抜くようになっている。 しかしながら、最近では、例えば大昭和精機株式会社の商品名「ビッグプラス」等で知られる、上記ＪＩＳ規格と同様のシャンク、ブルスタッドを備える２面拘束工具（以下、単に２面拘束工具と言う）を使用することが増えている。ＪＩＳ規格用工具ポットに２面拘束工具を挿入すると、工具ポット先端面と工具フランジの間に、工具抜用レバーを差込むための隙間を確保できず、ＪＩＳ規格の工具抜き用レバーを使用することができない。 また、２面拘束工具を工具ポットに挿入した際に、工具抜きレバーを挿入することを可能にするために、工具ポット先端面位置を後退させることが考えられるが、そのようした工具ポットに、ＪＩＳ規格の工具を挿入すると、レバーを差し込むための隙間が大きくなり過ぎて、工具の抜き取り作業が難しくなる。   When a JIS (B6339) standard tool is mounted on such a tool pot, a gap of several millimeters is generated between the tip surface of the tool pot and the flange provided on the tool. A tool removal lever is inserted into this gap, and the tool is pulled out according to the principle of leverage. However, recently, for example, a two-face constraining tool having a shank and a bull stud similar to the above-mentioned JIS standard known by the trade name “Big Plus” of Daishowa Seiki Co., Ltd. (hereinafter simply referred to as “two-face constraining tool”). The use of is increasing. When a two-face constrained tool is inserted into a JIS standard tool pot, a gap for inserting the tool extraction lever cannot be secured between the tool pot tip and the tool flange, and a JIS standard tool extraction lever is used. I can't. In addition, when inserting the two-face constraining tool into the tool pot, it is conceivable to retreat the tool pot tip surface position in order to enable insertion of the tool removal lever. When a JIS standard tool is inserted, the gap for inserting the lever becomes too large, making it difficult to remove the tool.

これらの理由から、２種類の工具に対してそれぞれ専用の工具ポットもしくはそれぞれ専用の工具抜き用レバーを用意する必要があり、作業者が誤って異なる工具抜きレバーを用いようとする等の作業ミスによるロスや、コストが高くなる等の問題があった。   For these reasons, it is necessary to prepare a dedicated tool pot or a dedicated tool release lever for each of the two types of tools, and the operator mistakenly uses a different tool release lever. There were problems such as loss due to the cost and high cost.

また、一部の工具ポットでは、工具引抜レバー機構を、工具ポットのそれぞれ内蔵および／または外装するようにしたものが知られている（例えば、引用文献１、引用文献２参照）。   Further, some tool pots are known in which a tool pull-out lever mechanism is incorporated and / or packaged in each tool pot (see, for example, cited document 1 and cited document 2).

このような工具ポットでは、工具引抜レバー機構を個々の工具ポットに装備する必要があり、その分、工具ポットの構造が複雑となり、工具ポットが高価についた。
特開２００２−２８８３５号公報 特開２００５−２８５４９号公報 In such a tool pot, it is necessary to equip each tool pot with a tool pull-out lever mechanism, and accordingly, the structure of the tool pot becomes complicated and the tool pot becomes expensive.
JP 2002-28835 A JP 2005-28549 A

この発明の目的は、共通の工具ポットと工具引抜レバーを使用して、工具引抜レバーによるテコの原理の支点と作用点の位置関係を２種類の工具に対して同等にすることのできる工具ポットを提供することにある。   An object of the present invention is to use a common tool pot and a tool pull-out lever to make the positional relationship between the fulcrum and the action point of the lever principle by the tool pull-out lever equivalent to two types of tools. Is to provide.

この発明による工具ポットは、工具を収納するための筒状工具ポットの先端に、内端面および外端面が設けられており、内端面および外端面間に、内端面から外端面を後退させた段差が設けられており、段差の大きさは、工具を工具ポットから引抜く際に用いられる板状工具引抜レバーの厚みよりも大であるものである。   In the tool pot according to the present invention, an inner end surface and an outer end surface are provided at the tip of a cylindrical tool pot for storing a tool, and a step is formed between the inner end surface and the outer end surface by retreating the outer end surface from the inner end surface. And the size of the step is larger than the thickness of the plate-shaped tool extraction lever used when the tool is extracted from the tool pot.

この発明による工具ポットでは、JIS規格工具を用いる場合、工具のフランジ側面および工具ポットの内端面間に工具引抜レバーを挿入させうる隙間が生じるし、２面拘束工具を用いる場合、工具のフランジ側面および工具ポットの外端面間に工具引抜レバーを挿入させうる隙間が生じる。   In the tool pot according to the present invention, when a JIS standard tool is used, there is a gap in which a tool pulling lever can be inserted between the side surface of the tool flange and the inner end surface of the tool pot. In addition, a gap is formed between the outer end surfaces of the tool pot so that the tool extraction lever can be inserted.

本発明では、JIS規格工具と２面拘束工具の両方に対して共通な工具ポットと工具引抜レバーを使用することができ、作業者が間違う恐れもなく、コストメリットも得ることができる。   In the present invention, a common tool pot and tool pulling lever can be used for both the JIS standard tool and the two-surface constraining tool, and there is no fear that the operator will make a mistake and cost merit can be obtained.

この発明の実施の形態を図面を参照しながらつぎに説明する。   Embodiments of the present invention will be described below with reference to the drawings.

＜実施の形態１＞

A tool extraction lever 15 is shown. In FIG. 2, the illustration of the flange 21 of the tool 12 is omitted.

工具12のシャンク11外面大径部のすぐ近くから立上がるようにフランジ21が設けられている。フランジ21の工具ポット側を向いた側面は、垂直状隙間形成面22となされている。シャンク11の基部には、小径係合軸部23がシャンク11と同軸状に設けられている。係合軸部23の先端には環状抜止突条24が設けられている。   A flange 21 is provided so as to stand up from the large diameter portion of the outer surface of the shank 11 of the tool 12. A side surface of the flange 21 facing the tool pot side is a vertical gap forming surface 22. A small diameter engagement shaft portion 23 is provided coaxially with the shank 11 at the base portion of the shank 11. An annular retaining protrusion 24 is provided at the tip of the engagement shaft portion 23.

工具ポット14の先端には、内端面25および外端面26が設けられている。内端面25は、工具ポット14の先端内縁部の全周にそってのびた環状のものである。外端面26は、工具ポット14の先端外縁部の全周にそってのびた環状のものである。内端面25および外端面26間には、内端面25から外端面26を後退させた段差27が設けられている。段差27の大きさＳは、工具引抜レバー15の厚みＴよりも大である。工具ポット14の、係合軸部23の抜止突条24と対応する位置には複数の半径方向ボール孔31があけけられている。各ボール孔31にはボール32が抜止突条24と係合するように挿入されるととも、ボール32を内向きに付勢するようにばね33が挿入されている。   An inner end face 25 and an outer end face 26 are provided at the tip of the tool pot 14. The inner end surface 25 has an annular shape extending along the entire circumference of the inner edge of the tip of the tool pot 14. The outer end surface 26 has an annular shape extending along the entire periphery of the outer edge portion of the tip end of the tool pot 14. Between the inner end surface 25 and the outer end surface 26, a step 27 is provided by retreating the outer end surface 26 from the inner end surface 25. The size S of the step 27 is larger than the thickness T of the tool extraction lever 15. A plurality of radial ball holes 31 are formed in the tool pot 14 at positions corresponding to the retaining protrusions 24 of the engagement shaft portion 23. In each ball hole 31, a ball 32 is inserted so as to engage with the retaining protrusion 24, and a spring 33 is inserted so as to urge the ball 32 inward.
