Description

この発明は、自動工具交換装置（以下、「ＡＴＣ」と言う）を備えた工作機械で用いる工具及びそのような工作機械のＡＴＣに関するものである。   The present invention relates to a tool used in a machine tool equipped with an automatic tool changer (hereinafter referred to as “ATC”) and an ATC of such a machine tool.

工具を装着して回転する回転工具軸と、その工具軸に装着される工具のＡＴＣとを備えた工作機械（以下、単に「工作機械」と言う）で使用する工具は、工具軸で把持されるシャンクと、ワークを加工する刃具（砥粒ないし砥石を含む意味で用いている。）とを備えている。また、ＡＴＣは、複数の工具を収容する工具マガジンと、この工具マガジンと工具軸との間で工具を受け渡しする交換装置とを備えている。   A tool used in a machine tool (hereinafter simply referred to as a “machine tool”) having a rotating tool axis that rotates with a tool mounted thereon and an ATC of a tool that is mounted on the tool axis is gripped by the tool axis. And a cutting tool for processing a workpiece (used to include abrasive grains or a grindstone). In addition, the ATC includes a tool magazine that houses a plurality of tools, and an exchange device that transfers the tool between the tool magazine and the tool axis.

工具軸と工具の結合は、開閉するチャックで工具のシャンクを把持する構造と、テーパシャンクとテーパ孔の嵌合による構造が一般的である。前者の構造では、シャンクは円筒状（ストレートシャンク）であり、後者の構造では、シャンクは刃先側が太い円錐状（テーパシャンク）である。図８は、テーパシャンク２１ｂを備えた工具２の従来の工具交換動作を模式的に示した図で、４１は工具マガジンのポット（工具ホルダ）、７は工具軸１とポット４１との間で工具２の受け渡しをする交換装置である。ポット４１は、工具のテーパシャンク２１ｂに嵌合する円錐凹面４２を備えており、工具２は、テーパシャンク２１ｂをこの円錐凹面４２に嵌合した状態でポット４１に保持される。   In general, the tool shaft and the tool are joined by a structure in which a tool shank is held by a chuck that opens and closes, and a structure in which a taper shank and a taper hole are fitted. In the former structure, the shank has a cylindrical shape (straight shank), and in the latter structure, the shank has a conical shape (tapered shank) with a thick blade edge. FIG. 8 is a diagram schematically showing a conventional tool changing operation of the tool 2 having the taper shank 21b, wherein 41 is a tool magazine pot (tool holder), and 7 is between the tool shaft 1 and the pot 41. This is an exchange device for delivering the tool 2. The pot 41 has a conical concave surface 42 that fits into the taper shank 21b of the tool, and the tool 2 is held by the pot 41 with the taper shank 21b fitted into the conical concave surface 42.

図の交換装置７は、１８０度旋回及び軸方向に進退する旋回軸７１の先端に両端にフィンガ７２を備えた旋回腕７３を装着した構造で、両端のフィンガ７２でポット４１に保持された工具の鍔２８と工具軸に保持された工具の鍔２８を把持して図で下動することにより、工具２、２を工具軸１及びポット４１から抜き取り、１８０度旋回して図で上方に移動することにより、工具２、２のテーパシャンク２１ｂを工具軸１及びポット４１に挿入することによって、ポット４１と工具軸１との間で工具２、２相互の交換を行うものである。   The illustrated exchanging device 7 has a structure in which a turning arm 73 having fingers 72 at both ends is attached to the tip of a turning shaft 71 that turns 180 degrees and advances and retreats in the axial direction, and is held in a pot 41 by fingers 72 at both ends. By grasping the rod 28 of the tool and the rod 28 of the tool held on the tool axis and moving downward in the figure, the tools 2 and 2 are extracted from the tool axis 1 and the pot 41, rotated 180 degrees and moved upward in the figure. Thus, by inserting the taper shank 21 b of the tools 2 and 2 into the tool shaft 1 and the pot 41, the tools 2 and 2 are exchanged between the pot 41 and the tool shaft 1.

このように、従来のＡＴＣの工具マガジンは、工具軸に把持されるシャンクの部分を工具マガジンに設けた工具ホルダで保持する（ポットタイプ）か、シャンクの根本に設けた鍔の部分を工具マガジンに設けたフィンガで保持する（フィンガタイプ）かして、交換される多数の工具を収容している。   As described above, in the conventional ATC tool magazine, the shank portion held by the tool shaft is held by the tool holder provided in the tool magazine (pot type), or the flange portion provided at the base of the shank is used as the tool magazine. A large number of tools to be replaced are accommodated by holding them with fingers (finger type).

しかし、ポットタイプのものは、工具軸と工具マガジンとの間で工具を受け渡しする交換装置が必要である。一方、フィンガタイプのものは、工具マガジンに設けた多数の工具ホルダにフィンガを設ける必要があり、工具マガジンの構造が複雑になると共に、工具交換時にフィンガの開閉が必要である。従って、ポットタイプ及びフィンガタイプのいずれも、ＡＴＣの構造が複雑になると共に、工具交換動作が複雑になるという問題がある。   However, the pot type device requires an exchange device for delivering a tool between the tool shaft and the tool magazine. On the other hand, in the finger type, it is necessary to provide fingers on a large number of tool holders provided in the tool magazine, the structure of the tool magazine becomes complicated, and the fingers need to be opened and closed when changing tools. Therefore, both the pot type and the finger type have a problem that the structure of the ATC is complicated and the tool changing operation is complicated.

この発明は、自動交換される工具をより簡単な動作で工具軸に着脱することが可能な工具、及びそのような工具を自動交換するためのＡＴＣを得ることを課題としている。   An object of the present invention is to obtain a tool that allows a tool to be automatically exchanged to be attached to and detached from a tool axis with a simpler operation, and an ATC for automatically exchanging such a tool.

この発明の工具は、工具軸に結合するシャンク２１（ストレートシャンク２１ａ又はテーパシャンク２１ｂ）と刃具３（砥石３ａ又はチップ３ｂ）とを備えた工作機械の自動交換用の工具２（２ａ〜２ｄ）において、シャンク２１と刃具３との間に、工具マガジンの工具ホルダ４に設けた円筒凹面４８又は上方が大径となった円錐凹面４２に嵌合される円筒面（以下、「保持円筒面」と言う。）３８又はシャンク２１側が大径で刃具３側が小径となった円錐面（以下、「保持円錐面」と言う。）２２を備えていることを特徴とするものである。   The tool of this invention is a tool 2 (2a to 2d) for automatic change of a machine tool provided with a shank 21 (straight shank 21a or tapered shank 21b) coupled to a tool shaft and a cutting tool 3 (grinding stone 3a or tip 3b). , A cylindrical surface (hereinafter referred to as “holding cylindrical surface”) that is fitted between the shank 21 and the cutting tool 3 on a cylindrical concave surface 48 provided on the tool holder 4 of the tool magazine or a conical concave surface 42 whose upper diameter is large. 38) or a conical surface 22 (hereinafter referred to as “holding conical surface”) 22 having a large diameter on the shank 21 side and a small diameter on the cutting tool 3 side is characterized.

この発明の工具２は、シャンク２１を工具軸のチャック（ストレートシャンクの場合）で把持するか、または工具軸のテーパ孔（テーパシャンクの場合）に嵌合して、刃具３側を下にした鉛直姿勢で工作機械の工具軸１に装着され、シャンク２１と刃具３との間に設けた保持円筒面３８又は保持円錐面２２を工具マガジン５の工具ホルダ４に設けた円筒凹面４８又は円錐凹面４２に嵌合した状態で、刃具３を下方にした鉛直姿勢で、工具マガジンの工具ホルダ４に保持される。従って工具ホルダ４は、円錐凹面４２の小径側に、刃具３及びこの刃具を保持しているボディ２５の部分が通過可能な開口４５を備えている。   In the tool 2 of the present invention, the shank 21 is gripped by a tool shaft chuck (in the case of a straight shank) or fitted into a taper hole (in the case of a taper shank) of the tool shaft, and the cutting tool 3 side is lowered. Cylindrical concave surface 48 or conical concave surface provided in tool holder 4 of tool magazine 5 with holding cylindrical surface 38 or holding conical surface 22 provided between tool shank 21 and cutting tool 3 mounted on tool axis 1 of the machine tool in a vertical posture. In a state of being fitted to 42, the tool 3 is held by the tool holder 4 of the tool magazine in a vertical posture in which the blade 3 is lowered. Therefore, the tool holder 4 is provided with an opening 45 through which the blade 3 and the portion of the body 25 holding the blade can pass on the small diameter side of the conical concave surface 42.

工具ホルダ４に上記のような開口４５を設けることが困難なとき、すなわち、工具の刃具が大きいために円筒凹面や円錐凹面の径が実用的でないほど大径になるときは、刃具３の反シャンク側に保持円錐面を設け、この保持円錐面と工具ホルダ側の円筒凹面との嵌合により、工具ホルダに工具を保持することもできる。しかしこの構造は、工具２の軸方向長さが短いときにのみ実用可能である。   When it is difficult to provide the opening 45 as described above in the tool holder 4, that is, when the diameter of the cylindrical concave surface or the conical concave surface becomes too large to be practical due to the large size of the tool blade, A holding conical surface is provided on the shank side, and the tool can be held in the tool holder by fitting the holding conical surface with the cylindrical concave surface on the tool holder side. However, this structure is practical only when the axial length of the tool 2 is short.

工具ホルダ４は工具２の軸を鉛直方向にして保持するので、工具２は自重により工具ホルダ４の円筒凹面４８又は円錐凹面４２に嵌合して、工具ホルダ４内での工具２の位置が保持される。工具ホルダに保持された工具の軸心の位置精度や傾き精度を高くしたいときは、保持円錐面２２と円錐凹面４２との嵌合により工具を保持するのが好ましい。この場合には、工具ホルダ４に、工具の保持円錐面２２を工具ホルダの円錐凹面４２に付勢する押接具６（６ａ、６ｂ）を設けるのが望ましい。   Since the tool holder 4 holds the axis of the tool 2 in the vertical direction, the tool 2 is fitted to the cylindrical concave surface 48 or the conical concave surface 42 of the tool holder 4 by its own weight, and the position of the tool 2 in the tool holder 4 is Retained. When it is desired to increase the position accuracy and inclination accuracy of the axis of the tool held by the tool holder, it is preferable to hold the tool by fitting the holding conical surface 22 and the conical concave surface 42 together. In this case, it is desirable to provide the tool holder 4 with a pressing member 6 (6a, 6b) for urging the holding conical surface 22 of the tool against the conical concave surface 42 of the tool holder.

この発明のＡＴＣは、工具軸１の工具装着端１１と、工具ホルダ４の円筒凹面４８の開口上端又は円錐凹面４２の大径側とを対向させた状態で、工具軸１の軸方向の進退動作とその進出端における工具軸側のチャックやプルロッドなどの工具把持装置の開閉動作とにより、工具軸１と工具マガジンの工具ホルダ４との間で、この発明の工具２を直接（交換装置を介さないで）装脱することを特徴とする。   The ATC of the present invention advances and retreats in the axial direction of the tool shaft 1 with the tool mounting end 11 of the tool shaft 1 facing the upper end of the opening of the cylindrical concave surface 48 of the tool holder 4 or the large diameter side of the conical concave surface 42. The tool 2 according to the present invention can be directly applied between the tool shaft 1 and the tool holder 4 of the tool magazine (by using an exchange device) by the operation and the opening / closing operation of the tool gripping device such as a chuck or pull rod on the tool shaft side at the advancing end. It is characterized by loading and unloading (without intervention).

この発明のＡＴＣは、工具軸１がその工具装着端１１を下方にした鉛直姿勢で工具交換を行う工作機械に特に適している。そのような工作機械では、工具マガジンの工具ホルダ４に工具２が、その保持円筒面３８又は保持円錐面２２を工具ホルダの円筒凹面４８又は円錐凹面４２に自重により嵌合する状態で保持されるので、保持円筒面３８又は保持円錐面２２と円筒凹面４８又は円錐凹面４２との工具軸方向の嵌合長さが比較的短くても工具２を正確な鉛直姿勢で工具軸１から工具ホルダ４に受け渡すことができ、従って、工具２が工具ホルダ４に正確な姿勢で保持されるから、次にその工具を工具軸１に装着するとき、当該工具が正確に工具軸１に装着されるからである。   The ATC according to the present invention is particularly suitable for a machine tool that performs tool change in a vertical posture in which the tool shaft 1 has its tool mounting end 11 downward. In such a machine tool, the tool 2 is held in the tool holder 4 of the tool magazine in a state where its holding cylindrical surface 38 or holding conical surface 22 is fitted to the cylindrical concave surface 48 or conical concave surface 42 of the tool holder by its own weight. Therefore, even if the fitting length in the tool axis direction between the holding cylindrical surface 38 or holding conical surface 22 and the cylindrical concave surface 48 or conical concave surface 42 is relatively short, the tool 2 can be moved from the tool axis 1 to the tool holder 4 in an accurate vertical posture. Therefore, since the tool 2 is held in the tool holder 4 in an accurate posture, the tool is mounted on the tool shaft 1 when the tool is mounted on the tool shaft 1 next time. Because.

この発明のＡＴＣの工具交換位置は、工具軸１の移動領域内で当該工具軸の軸心と、交換される工具を保持する工具ホルダの軸心とが正確に一致する位置に設定される。この工具交換位置は、工具軸の移動領域内の複数位置に設定することが可能である。工具マガジンに多数の工具ホルダ４を設けるときは、従来のＡＴＣと同様に、工具ホルダを工具交換位置から退避させる往復動装置や周回装置を設けてやればよい。工具軸を鉛直方向下向きにして工具交換を行う工作機械では、工具ホルダの鉛直方向上向きの姿勢を保持して往復動ないし周回移動させる構造がより好ましい。   The tool change position of the ATC according to the present invention is set to a position where the axis of the tool axis and the axis of the tool holder holding the tool to be exchanged exactly coincide within the movement range of the tool axis 1. This tool change position can be set at a plurality of positions within the movement region of the tool axis. When a large number of tool holders 4 are provided in the tool magazine, a reciprocating device or a revolving device for retracting the tool holder from the tool change position may be provided as in the conventional ATC. In a machine tool for exchanging tools with the tool axis facing downward in the vertical direction, a structure in which the tool holder is held in a vertically upward position and reciprocated or revolved is more preferable.

この発明のＡＴＣは、工具マガジンの工具ホルダ４と工作機械の工具軸１との間で工具が直接受け渡しされるため、交換装置を設けることによる機械の複雑化と、交換装置との受け渡し時に生ずる軸心位置の誤差の発生を避けることができるので、ＡＴＣの構造及び工具の交換動作を単純化することができると共に、自動交換される工具を工作機械の工具軸により正確に装着することができるという効果がある。   In the ATC of the present invention, since the tool is directly transferred between the tool holder 4 of the tool magazine and the tool axis 1 of the machine tool, the machine is complicated by providing the changing device, and occurs when the tool is transferred to the changing device. Since it is possible to avoid the occurrence of an error in the axial center position, it is possible to simplify the structure of the ATC and the tool changing operation, and it is possible to mount the automatically changed tool more accurately on the tool axis of the machine tool. There is an effect.

この発明の工具は、工具マガジン内で、工具に設けた保持円筒面３８又は保持円錐面２２と工具マガジンの工具ホルダに設けた円筒凹面４８又は円錐凹面４２との嵌合により保持されている。保持円筒面３８や保持円錐面２２は、シャンク２１と刃具３との間、従ってシャンク２１より刃具３に近い位置に設けられているので、テーパシャンクを工具マガジンのポットに嵌合して工具を保持する従来構造と比較しても、嵌合部が刃具３に近い分だけ刃具３の位置をより正確な位置にした状態で工具が工具マガジンに保持されることとなり、しかもその工具が交換装置を介さないで直接工具軸に装着されるので、より高い精度で工具を工具軸に装着することができる。   The tool of the present invention is held in the tool magazine by fitting a holding cylindrical surface 38 or holding conical surface 22 provided on the tool with a cylindrical concave surface 48 or conical concave surface 42 provided on the tool holder of the tool magazine. Since the holding cylindrical surface 38 and the holding conical surface 22 are provided between the shank 21 and the cutting tool 3, and therefore closer to the cutting tool 3 than the shank 21, the taper shank is fitted into the pot of the tool magazine to operate the tool. Compared with the conventional structure to hold, the tool is held in the tool magazine in a state in which the position of the cutting tool 3 is more accurate by the amount of the fitting portion closer to the cutting tool 3, and the tool is replaced by an exchange device. Since the tool is mounted directly on the tool axis without using a tool, the tool can be mounted on the tool axis with higher accuracy.

工具の保持円錐面２２と工具ホルダの円錐凹面４２との嵌合によるときは、工具マガジンの工具ホルダ４に工具２を軸心のずれや傾きのない姿勢で保持することができ、かつ工具軸１と工具ホルダ４との間で交換装置を介することなく直接工具を受け渡すことができるため、工具軸１と工具ホルダ４との間で工具２を高い精度で受け渡すことができ、従って工具軸１に装着された工具２の軸心のずれや傾きを最小限にした、高い精度での工具の装着が可能になるこの効果は、工具軸１と工具２との結合部に高い調心作用を備えさせることが困難なストレートシャンクの工具に対して特に有効である。   When the tool holding conical surface 22 and the conical concave surface 42 of the tool holder are fitted to each other, the tool 2 can be held in the tool holder 4 of the tool magazine in a posture with no axial center deviation or inclination, and the tool axis. Since the tool can be directly transferred between the tool holder 4 and the tool holder 4 without using an exchange device, the tool 2 can be transferred between the tool shaft 1 and the tool holder 4 with high accuracy. The effect of enabling the tool to be mounted with high accuracy while minimizing the deviation and inclination of the axis of the tool 2 mounted on the shaft 1 is the result of high alignment at the joint between the tool shaft 1 and the tool 2. This is particularly effective for a straight shank tool that is difficult to provide an action.

以下、図面を参照して、この発明の工具及びＡＴＣについて更に説明する。図１は、この発明の工具の一例を示した図で、ガラス板の孔明け及び内周縁の加工を行う砥石の例を示した図である。   Hereinafter, the tool and ATC of the present invention will be further described with reference to the drawings. FIG. 1 is a view showing an example of the tool of the present invention, and is a view showing an example of a grindstone for drilling a glass plate and processing an inner peripheral edge.

図１に示した小径砥石３ａは、基本形状が細い円筒形で、その先端面３１は、ガラス板を砥石軸方向に切り進む研削面とされ、当該先端面には、研削作用が発揮されない中心部がガラス板に接触するのを防止すると共に加工液を流通させるための直径方向の溝３２が設けられている。砥石３ａの先端部外周は、先端側が小径となる円錐面３３とされ、それに続く円筒面３４と、鼓形部３５とを備えている。鼓形部３５の両側の円錐面３６、３７は、くり貫いた孔の周面の表裏のエッジを斜めに削り落とす、いわゆる面取を行うための研削面となっている。   The small-diameter grindstone 3a shown in FIG. 1 has a cylindrical shape with a thin basic shape, and its tip surface 31 is a grinding surface that cuts a glass plate in the direction of the grindstone axis. A diametrical groove 32 is provided for preventing the portion from contacting the glass plate and allowing the machining fluid to flow. The outer periphery of the front end portion of the grindstone 3 a is a conical surface 33 having a small diameter on the front end side, and includes a cylindrical surface 34 and a hourglass portion 35 that follow the conical surface 33. The conical surfaces 36 and 37 on both sides of the hourglass portion 35 are grinding surfaces for so-called chamfering, where the front and back edges of the peripheral surface of the bored hole are scraped off obliquely.

The cylindrical concave surface 48 includes a bottom edge 49 that engages with the step 27 on the tool side, and the step 27 and the bottom edge 49 abut on the holding cylindrical surface 38 of the tool 2c by the pressing force of the ball plunger 6a. In the state, it is fitted and held in the cylindrical concave surface 48 of the tool holder 4.

シャンク２１ａを把持する工具軸のチャックほ、挿入されたシャンクの僅かな軸ずれを修正して把持する機能を備えているのが普通であり、保持円筒面３８と円筒凹面４８との径差がこの許容される軸ずれの範囲内になるように保持円筒面３８と円筒凹面４８を精度良く加工することにより、保持円筒面３８と円筒凹面４８の嵌合で工具２ｃを工具ホルダ４に実用上十分な精度で保持することかできる。   The chuck of the tool shaft that grips the shank 21a usually has a function of correcting and gripping a slight axial deviation of the inserted shank, and there is a difference in diameter between the holding cylindrical surface 38 and the cylindrical concave surface 48. By practically processing the holding cylindrical surface 38 and the cylindrical concave surface 48 so as to be within the range of the allowable axis deviation, the tool 2c is practically used as the tool holder 4 by fitting the holding cylindrical surface 38 and the cylindrical concave surface 48. It can be held with sufficient accuracy.

図６は、この発明の工具とＡＴＣの工具ホルダの第３実施例を示した図で、テーパシャンク２１ｂと従来構造の交換装置の把持爪で工具を把持するための鍔２８とを備えた工具２ｂにこの発明を適用した例である。第３実施例の工具２ｂは、工具軸のテーパ孔に嵌合するテーパシャンク２１ｂと、装着された工具を引き上げてテーパシャンク２１ｂと工具軸のテーパ孔とをしっかりと嵌合させるためのプルロッドを係止するフック２９とを備えている。更に工具２ｂは、従来構造のＡＴＣでも利用できるように工具軸と工具マガジンとの間で工具を受け渡す交換装置のフィンガで保持される鍔２８を備えている。３ｂは刃具となるチップ、２５はチップ３ｂを固定するボディである。シャンク２１ｂ側が大径でチップ３ｂ側が小径となる保持円錐面２２は、鍔２８とボディ２５との間に設けられている。   FIG. 6 is a view showing a third embodiment of the tool of the present invention and the tool holder of the ATC, and a tool provided with a taper shank 21b and a hook 28 for gripping the tool with the gripping claws of the exchange device having the conventional structure. This is an example in which the present invention is applied to 2b. The tool 2b according to the third embodiment includes a taper shank 21b that fits into the taper hole of the tool shaft, and a pull rod that pulls up the attached tool to firmly fit the taper shank 21b and the taper hole of the tool shaft. And a hook 29 to be locked. Further, the tool 2b is provided with a rod 28 held by a finger of an exchange device for transferring the tool between the tool shaft and the tool magazine so that it can be used in the ATC having the conventional structure. 3b is a chip | tip used as a cutting tool, 25 is a body which fixes the chip | tip 3b. A holding conical surface 22 having a large diameter on the shank 21 b side and a small diameter on the tip 3 b side is provided between the flange 28 and the body 25.

工具マガジンの周回テーブル５１に装着された工具ホルダ４は、工具の保持円錐面２２に嵌合する円錐凹面４２を備えており、その小径側には、チップ３ｂとボディ２５とが通過可能な開口４５が貫通している。工具ホルダ４には、円錐凹面４２の軸心と交差する支軸６６に軸支されて巻ばね６５で押接端６７を円錐凹面４２側に向けて付勢した押え駒６ｂが設けられている。この押え駒６ｂは、支軸６６から反押接端側へと延びるレバー６８を備えており、工具交換位置で図示しないアクチュエータ（エアシリンダなど）にレバー６８が押動されたときに押接端６７が上方へと回動し、工具ホルダ４に挿脱される工具の鍔２８と押え駒６ｂとの干渉が回避される。   The tool holder 4 mounted on the rotating table 51 of the tool magazine has a conical concave surface 42 that fits into the holding conical surface 22 of the tool, and an opening through which the tip 3b and the body 25 can pass on the small diameter side. 45 penetrates. The tool holder 4 is provided with a presser piece 6b that is pivotally supported by a support shaft 66 that intersects with the axis of the conical concave surface 42 and is biased by a winding spring 65 toward the conical concave surface 42 side. . The presser piece 6b includes a lever 68 that extends from the support shaft 66 to the side opposite to the pressing end. When the lever 68 is pushed by an actuator (such as an air cylinder) (not shown) at the tool change position, the pressing end 6b is pressed. 67 is rotated upward, and interference between the tool collar 28 inserted into and removed from the tool holder 4 and the presser piece 6b is avoided.

工具軸１と工具ホルダ４との間で工具２ｂを受け渡すときは、押え駒６ｂの押接端６７が上方へ回動した状態で行われ、交換動作が終了した後、前記アクチュエータが退避して、押え駒６ｂの押接端６７が巻ばね６５の付勢力により、工具ホルダ４に保持された工具の鍔２８を円錐凹面４２側へと押して、工具２ｂが工具ホルダ４から脱落するのを防止する。工具ホルダ４が工具交換位置から退避した状態で押え駒６ｂは巻ばね６５の付勢力により常時保持した工具の保持円錐面２２を工具ホルダの円錐凹面４２に付勢した状態で工具を保持している。これにより、工具２ｂと工具ホルダ４の軸心のずれや傾きが防止され、工具ホルダ４に保持された工具が再度工具軸１に装着されてるときの工具軸１と工具２ｂの軸心のずれや傾きを防止することができる。   When the tool 2b is transferred between the tool shaft 1 and the tool holder 4, the pressing end 67 of the presser piece 6b is rotated upward, and after the replacement operation is completed, the actuator is retracted. Thus, the pressing end 67 of the presser piece 6b pushes the collar 28 of the tool held by the tool holder 4 to the conical concave surface 42 side by the urging force of the winding spring 65, and the tool 2b is removed from the tool holder 4. To prevent. With the tool holder 4 retracted from the tool replacement position, the presser piece 6b holds the tool in a state where the holding conical surface 22 of the tool that is always held by the urging force of the winding spring 65 is urged against the conical concave surface 42 of the tool holder. Yes. As a result, misalignment and inclination of the axis between the tool 2b and the tool holder 4 are prevented, and the misalignment between the tool axis 1 and the tool 2b when the tool held in the tool holder 4 is mounted on the tool axis 1 again. And tilting can be prevented.
