Description

本発明は、ワークにネジ孔を形成する際に、工具回転タイプの工作機側の回転中心に対しワーク側の孔の中心位置に誤差が生じた場合や、ワーク回転タイプの工作機で回転中心に対し孔の中心位置に誤差が生じた場合であってもそのまま加工可能にした自動調芯工具ホルダーに関する。   In the present invention, when a screw hole is formed in a workpiece, when an error occurs in the center position of the hole on the workpiece side with respect to the rotation center on the tool rotation type machine tool side, On the other hand, the present invention relates to an automatic alignment tool holder that can be processed as it is even when an error occurs in the center position of a hole.

従来、タップなどの工具のホルダーとしては、シャンク部に一体的または個別に設けられる固定部、工具が取着される移動部、および前記固定部と前記移動部の間に一体的または個別に設けられ、前記工具を前記シャンク部の軸方向に直交する径方向の中、一つの直線方向にのみ移動自在な互いに平行な対をなす平板状弾性部を有するハウジングを備えることで、工具が取着されるハウジング自体に位置調整機能を有させた工具位置調整構造が見受けられる(例えば、特許文献1参照)。   Conventionally, as a holder for a tool such as a tap, a fixed part provided integrally or individually on a shank part, a moving part to which a tool is attached, and provided integrally or individually between the fixed part and the moving part The tool is attached by providing a housing having flat elastic portions that are parallel to each other and movable in only one linear direction in a radial direction orthogonal to the axial direction of the shank portion. There is a tool position adjustment structure in which the housing itself has a position adjustment function (see, for example, Patent Document 1).

特開平11−254210号公報(請求項1、段落番号〔0008〕、〔0009〕、〔0017〕、〔0018〕、図1)JP-A-11-254210 (Claim 1, paragraph numbers [0008], [0009], [0017], [0018], FIG. 1)

しかし、上記ホルダーにあっては、確かに工具自体を動かさずに工具を取り付けたハウジングを動かすことが可能であるが、これはあくまでも軸芯を揃えることを目的としたものであるため、ワークとの誤差を修正するには至らないないことから、工具装着後に位置調整を補正すべく工具側の設定を変更することで対応する必要があり、而も位置補正を行ったとしても微小誤差は残ってしまうため、結果としてそのまま加工することになり、例えば工具がタップの場合、ワーク側の孔の中心と工具中心が僅かにズレた状態で加工することになるため、正確には極僅かな加工不良が発生しているにも拘らず良品としているのが現状であり、且つ工具にかかる負担が大きいため、その寿命が短くなるなど、解決せねばならない課題があった。   However, in the above holder, it is possible to move the housing to which the tool is attached without moving the tool itself, but this is only for the purpose of aligning the axis, Therefore, it is necessary to change the setting on the tool side to correct the position adjustment after mounting the tool. Even if the position correction is performed, a minute error remains. As a result, machining is performed as it is. For example, when the tool is a tap, machining is performed with the center of the hole on the workpiece side slightly shifted from the tool center. There are problems that must be solved, such as the fact that they are considered good products despite the occurrence of defects and the burden on the tools is large, so that the service life is shortened.

本発明は、上記従来技術に基づく、工具交換の度に調整作業をしても微小誤差が残る課題に鑑み、工作機側への装着部位と、該装着部位の前部に配した工具取付部位とを備え、該工具取付部位を装着部位に、装着部位の中心軸に対し直交方向且つ全周方向に微動可能に取り付けると共に、装着部位及び工具取付部位を夫々の中心軸を中心に同期回転可能にし、具体的には、装着部位を、装着部位本体と、該装着部位本体の前部に、該装着部位本体の中心軸に対し直交方向に微動可能に取り付けた連動部材とし、該連動部材の前方に工具取付部位を設けると共に、該工具取付部位を連動部材に対し、該連動部材の微動方向に対し直交方向に微動可能にしたホルダーに工具を装着して工作機に装着するか、工作機に組み込まれたホルダーに工具を装着することによって、加工前に工具だけが抵抗の少ない側、即ちワーク側の孔の中心に工具の軸芯が揃う様に自動的に位置補正すると共にその位置が孔により規制され、且つその状態を維持したまま加工工程に移行可能にすることによって、加工状態における工具の軸芯と回転中心がズレたままでも、工具の軸芯とワーク側の孔の中心が揃った状態で加工可能にして、上記課題を解決する。   The present invention is based on the above-described prior art, in view of the problem that a minute error remains even after adjustment work every time the tool is changed, a mounting part on the machine tool side, and a tool mounting part arranged at the front of the mounting part The tool attachment part is attached to the attachment part so as to be finely movable in the direction orthogonal to the center axis of the attachment part and in the entire circumferential direction, and the attachment part and the tool attachment part can be rotated synchronously about the respective central axes. Specifically, the mounting part is an interlocking member that is attached to the mounting part main body and the front part of the mounting part main body so as to be finely movable in a direction perpendicular to the central axis of the mounting part main body. A tool mounting part is provided in the front, and the tool mounting part is attached to the machine tool by attaching the tool to a holder that is movable with respect to the interlocking member in the direction perpendicular to the fine movement direction of the interlocking member. Tool in the holder built in By attaching the tool, the position of the tool is automatically corrected so that the center of the tool is aligned with the center of the hole on the workpiece side, that is, the center of the tool, and the position is regulated by the hole. By making it possible to shift to the machining process while maintaining the tool, it is possible to perform machining with the tool axis and the center of the hole on the workpiece side aligned, even if the tool axis and rotation center in the machining state remain misaligned. Solve the above problems.

要するに本発明は、工作機側への装着部位と、該装着部位の前部に配した工具取付部位とを備え、該工具取付部位を装着部位に、装着部位の中心軸に対し直交方向且つ全周方向に微動可能に取り付けたので、具体的には装着部位の半径方向のどの方向へも工具取付部位が微動可能になるため、工作機側の回転中心に対しワーク側の孔がどの方向にズレていたとしても対応させることか出来、而も装着部位及び工具取付部位を夫々の中心軸を中心に同期回転可能にしたので、工具の軸芯とワーク側の孔の中心がズレたまま加工することが出来るため、工具交換毎の調整作業が不要にすることが出来、よって工具自体への負担を軽減出来ると共に、正確に加工することが出来る。
又、装着部位を、装着部位本体と、該装着部位本体の前部に、装着部位本体の中心軸に対し直交方向に微動可能に取り付けた連動部材とし、該連動部材の前方に工具取付部位を設けると共に、該工具取付部位を連動部材に対し、該連動部材の微動方向に対し直交方向に微動可能にしたので、装着部位本体の回転を連動部材を介して工具取付部位に伝えることが出来、且つ装着部位本体と工具取付部位を同期回転させることが出来ることから、例え工具取付部位に装着した工具の軸芯と、工具取付部位の回転中心とがズレたとしても、連動部材が工具取付部位に対する工具取付部位の位置補正を補うため、工具の軸芯を動かさずに加工することが出来る。
又、装着部位本体及び連動部材と工具取付部位及び連動部材の摺接面の一方にスライド突起を、他方に該スライド突起に対応するスライド溝を設けたので、簡単な構造であらゆる方向へ微動させることが出来るため、低コストで製造することか出来る。
In short, the present invention includes a mounting part on the machine tool side and a tool mounting part arranged at the front of the mounting part, and the tool mounting part is set to the mounting part in a direction orthogonal to the central axis of the mounting part. Since the tool mounting part can be finely moved in any direction in the radial direction of the mounting part because it is mounted in the circumferential direction so that it can be finely moved, in which direction the hole on the workpiece side is in relation to the rotation center on the machine tool side. Even if it is misaligned, it can be handled, and since the mounting part and tool mounting part can be rotated synchronously around the respective center axes, machining is performed with the center of the tool axis and the center of the hole on the workpiece side misaligned. Therefore, it is possible to eliminate the need for adjustment work every time the tool is changed, and thus the burden on the tool itself can be reduced and machining can be performed accurately.
Further, the mounting part is an interlocking member that is attached to the mounting part main body and the front part of the mounting part main body so as to be finely movable in a direction orthogonal to the central axis of the mounting part main body, and the tool mounting part is disposed in front of the interlocking member. While providing the tool attachment site with respect to the interlocking member, it is possible to finely move in the direction perpendicular to the direction of fine movement of the interlocking member, so that the rotation of the mounting site body can be transmitted to the tool attachment site via the interlocking member, In addition, since the attachment part body and the tool attachment part can be rotated synchronously, even if the axis of the tool attached to the tool attachment part and the rotation center of the tool attachment part are misaligned, the interlocking member remains in the tool attachment part. In order to compensate for the position correction of the tool mounting part with respect to the tool, it is possible to perform machining without moving the tool axis.
In addition, a slide protrusion is provided on one of the sliding contact surfaces of the mounting part main body and the interlocking member, the tool attachment part and the interlocking member, and a slide groove corresponding to the slide protrusion is provided on the other, so that it can be slightly moved in any direction with a simple structure. Can be manufactured at low cost.

工具取付部位を、頭部と該頭部の後端部より後方突設した軸部とにより構成し、装着部位本体に挿通孔を、連動部材に貫通孔を夫々形成して上記軸部を遊貫状態としたので、装着部位本体及び連動部材に対し工具取付部位がスライドしても、その軸部が装着部位本体及び連動部材に当接しないため、スムーズなスライドを確保することが出来、而も上記挿通孔内に圧縮バネを挿設し、軸部の後端部にバネ受け部を設けると共に、貫通孔内に圧縮バネの当接部位を形成したので、装着部位本体の前面に対し連動部材の後面を、連動部材の前面に対し工具取付部位の頭部の後面を夫々密接状態にすることか出来るため、工具取付部位、連動部材及び装着部位本体の一体性の向上を図ることが出来る。
而も、例えば1インチの山の数が規定されたネジ孔の加工の場合、ピッチをミリメートル換算すると割り切れないことから、少数点数桁以降は切り捨てて対応しているため、正確な送り量で加工することが不可能であったり、通常のネジ孔加工の場合でも、ワーク又は工具の送り量とネジ孔のピッチが完全に一致することがないことから、正確には極僅かな加工不良が発生していることになるが、本願のものは、工作機側への装着部位に対し工具取付部位が中心軸方向に突出可能、即ち伸長可能であることから、ワークに対するタップ(工具)の自進作用を利用して、ワーク又は工具の送り量をネジ孔のピッチより若干少なく設定しておくことで、加工中に徐々に伸長して対応させることか出来、どのようなピッチのネジ孔加工であっても対応させることが出来る。
又、圧縮バネとバネ受け部間にスラスト軸受を介設したので、圧縮バネによりバネ受け部を押圧しつつ、圧縮バネを変形させずに工具取付部位だけを装着部位本体に対しスライドさせることが出来るため、更にスムーズなスライドを確保することが出来る。
而も、本願に係る自動調芯工具ホルダーにあっては、従来の工具ホルダーにおけるシャンク部に相当する部位、即ち工作機側への装着部位内に、工具取付部位における軸部、圧縮バネ、スラスト軸受を設けたことで、工作機からの突出部位の構成を簡略化出来るため、かかる突出部位の突出量を抑えてコンパクト化を図ることが出来、よって装着状態の突出量は従来の一般的なホルダーと略同じになり、近年小型化が進んだNC旋盤であっても、広い作業スペースを確保することが出来る。
尚且つ、従来の工具ホルダーにあっては、シャンク部より先端側の部位で工具の基端側を装着固定していることから、加工時に工具の先端に「振れ」が生じワーク側の孔に対し斜め方向に差し込まれることで、加工不良、工具への負担増などの不具合が発生し易いが、本願のものは、工具を装着する工具取付部位が工作機側への装着部位に、工具の軸芯に対し直交方向に微動可能に取り付けられ、而も装着部位における軸部が装着部位側に挿通状態であるため、恰も工具の基端側が装着部位内を挿通状態であるかの様な形態になり、且つスライド突起及びスライド溝により全周方向への微動が可能になると共に、圧縮バネにより工具取付部位、連動部材及び装着部位本体間の密接化が図られていることからも、工具が常に装着部位の中心と平行な状態を維持可能なため、常に工具の軸芯をワーク側の孔に一致させて加工することが出来、よって加工精度の向上を図ることが出来ると共に、工具への余分な負担を無くして寿命の短縮化を防止することが出来、特にネジ孔加工、リーマ加工に最適なホルダーを提供出来る。
The tool mounting part is composed of a head part and a shaft part projecting rearward from the rear end part of the head part, and an insertion hole is formed in the mounting part main body, and a through hole is formed in the interlocking member to play the shaft part. Since the tool mounting part slides with respect to the mounting part main body and the interlocking member, the shaft portion does not contact the mounting part main body and the interlocking member, so that smooth sliding can be secured. In addition, a compression spring is inserted into the insertion hole, a spring receiving part is provided at the rear end of the shaft part, and a contact part of the compression spring is formed in the through hole. Since the rear surface of the member can be in close contact with the rear surface of the head of the tool mounting portion with respect to the front surface of the interlocking member, the integrity of the tool mounting portion, the interlocking member, and the mounting portion main body can be improved. .
For example, in the case of machining a screw hole with a specified number of 1-inch threads, the pitch is not divisible when converted to millimeters. This is impossible, and even in the case of normal screw hole machining, the feed amount of the workpiece or tool and the pitch of the screw holes do not completely match, so there is an extremely slight machining defect. However, since the tool mounting part can protrude in the direction of the central axis with respect to the mounting part on the machine tool side, that is, it can be extended, the tap (tool) self-advances with respect to the workpiece. By using the action, the workpiece or tool feed amount is set slightly smaller than the pitch of the screw holes, so that it can be gradually extended during processing to cope with any pitch screw hole processing. Even if there is It is to it can be.
In addition, since the thrust bearing is interposed between the compression spring and the spring receiving portion, only the tool mounting portion can be slid with respect to the mounting portion main body without deforming the compression spring while pressing the spring receiving portion with the compression spring. As a result, a smoother slide can be secured.
In the self-aligning tool holder according to the present application, the shaft portion, the compression spring, the thrust at the tool mounting portion is included in the portion corresponding to the shank portion in the conventional tool holder, that is, the mounting portion on the machine tool side. By providing a bearing, the structure of the projecting part from the machine tool can be simplified, so that the projecting amount of the projecting part can be reduced and the size of the projecting part can be reduced. It is almost the same as the holder, and a large working space can be secured even for NC lathes that have been downsized in recent years.
In addition, in the conventional tool holder, since the base end side of the tool is mounted and fixed at the tip end side from the shank part, “runout” occurs at the tip end of the tool during processing, and the hole on the workpiece side However, it is easy to cause problems such as processing defects and increased burden on the tool by inserting it in an oblique direction.However, in the present application, the tool mounting part where the tool is mounted is placed at the mounting part on the machine tool side. It is attached so that it can be finely moved in the direction perpendicular to the shaft core, and the shaft part at the mounting part is inserted into the mounting part, so that the base end side of the tool is inserted through the mounting part. Since the slide projection and the slide groove enable fine movement in the entire circumferential direction, and the close contact between the tool mounting part, the interlocking member, and the mounting part main body is achieved by the compression spring, the tool is Always center and flat on the attachment site Therefore, it is possible to always machine with the tool axis aligned with the hole on the workpiece side, so that the machining accuracy can be improved and there is no extra burden on the tool. This makes it possible to provide a holder that is particularly suitable for screw hole machining and reamer machining.

少なくとも工具取付部位の後端部位から装着部位本体の先端部位を覆う筒状のカバーを備え、該カバーの前端部を工具取付部位に固定すると共に、カバーと連動部材及び装着部位本体との間に隙間を形成したので、加工時の切粉、切屑などが工具取付部位と連動部材との間、及び連動部材と装着部位本体との間、特に伸長時に拡開した工具取付部位と連動部材との間に入り込まないため、円滑なる微動を確保することが出来る。
而も、カバーの後端内周に鍔部を周設すると共に、該鍔部の内周と装着部位本体間に隙間を形成し、工具取付部位に対しスライド可能に外嵌した上記隙間の閉鎖リングをカバー内に配置すると共に、閉鎖リングの外周部とカバーの内周面間に隙間を形成し、カバーと連動部材及び装着部位本体との間の隙間に配置した圧縮バネの前端を工具取付部位側に、後端を閉鎖リングに当接させたので、カバー後方側からカバーと連動部材及び装着部位本体との間に隙間内への切粉、切屑などの侵入を完全に防止することが出来る。
A cylindrical cover that covers at least the rear end portion of the tool mounting portion from the tip end portion of the mounting portion main body is provided, the front end portion of the cover is fixed to the tool mounting portion, and between the cover, the interlocking member, and the mounting portion main body. Since the gap is formed, chips and chips during processing are between the tool attachment part and the interlocking member, and between the interlocking member and the attachment part main body, especially between the tool attachment part and the interlocking member that are expanded when extended. Smooth tremors can be ensured because it does not go in between.
In addition, a collar is provided around the inner periphery of the rear end of the cover, and a gap is formed between the inner periphery of the collar and the mounting part body, and the gap is closed so as to be slidably fitted to the tool mounting part. The ring is placed in the cover, a gap is formed between the outer periphery of the closing ring and the inner peripheral surface of the cover, and the front end of the compression spring placed in the gap between the cover, the interlocking member, and the attachment site body is attached to the tool. Since the rear end is brought into contact with the closing ring on the part side, it is possible to completely prevent chips and chips from entering the gap between the cover, the interlocking member, and the attachment part main body from the rear side of the cover. I can do it.

装着部位本体における挿通孔の内周面、又は連動部材及び装着部位本体における貫通孔及び挿通孔の内周面のに複数個の押圧体を半径方向に進退自在に設けると共に、該押圧体の後部に軸部側への付勢手段を設けたので、外力が作用しない状態において上記軸部を挿通孔の中央に位置させることが出来、而も軸部が動く際にも押圧体が常に軸部の外周面に当接させた状態を維持出来ることから、装着部位に対する軸部の平行姿勢を維持するための補助的役割を担わすことが出来、而も連動部材及び装着部位本体の両方に設ければ、軸部を装着部位の中心軸に対し常に平行状態を維持し易くなり、更に連動部材及び装着部位本体で取付位置を変えることで更に維持し易くなるため、加工中の工具の姿勢を正しい位置に保持させ易くすることが出来るなど、その実用的効果甚だ大である。   A plurality of pressing bodies are provided in the inner peripheral surface of the insertion hole in the mounting part main body, or on the inner peripheral surface of the through hole and the insertion hole in the interlocking member and the mounting part main body so as to be movable forward and backward in the radial direction, and the rear part of the pressing body Since the biasing means for the shaft portion is provided on the shaft portion, the shaft portion can be positioned at the center of the insertion hole in a state where no external force is applied. Since it can maintain the state of being in contact with the outer peripheral surface, it can play an auxiliary role for maintaining the parallel posture of the shaft portion with respect to the mounting part, and is provided in both the interlocking member and the mounting part main body. Therefore, it is easy to maintain the shaft part parallel to the central axis of the mounting part, and it becomes easier to maintain by changing the mounting position between the interlocking member and the mounting part main body. It may be easier to hold it in the correct position. Runado, its practical effect very large.

The interlock member 4 and the mounting part main body 3 are provided with a means for positioning the shaft portion 13 of the tool attachment part 2 in the center of the insertion hole 5. Compression springs 31, 31 a as biasing means accommodated in the inner side of the mounting holes 30, 30 a... Formed in the radial direction opening in the circumferential surface, and hemispherical pressing bodies 32, 32 a accommodated in the opening side In the mounting part main body 3, the mounting part main body 3 is accommodated in the inner side of the mounting holes 33, 33a formed radially in the opening side inner peripheral surface of the insertion hole 5 of the mounting part main body 3. A compression spring 34, 34a as an urging means and a hemispherical pressing body 35, 35a accommodated on the opening side, and a mounting site main body The side of the mounting holes 33, 33a ..., and is located centrally between the mounting holes 30, 30a ... of the interlocking member 4 side.
Then, the pressing members 32, 32a,..., 35, 35a... Are urged toward the shaft portion 13 by the compression springs 31, 31a. By abutting, the shaft portion 13 is positioned at the center of the insertion hole 5 in a state where no external force is applied.
In addition, in the mounting holes 30, 30a, ..., 33, 33a ..., through-holes from the outer peripheral surface to the inner peripheral surface of the interlocking member 4 and the mounting site main body 3 are screwed into the two screw plugs from the outer peripheral side. Then, it is formed by closing, and it is not loosened by vibration during processing by inserting two screw plugs.
In the drawing, the means for positioning the shaft portion 13 in the center of the insertion hole 5 is provided in both the interlocking member 4 and the attachment part main body 3, but at least provided in the attachment part main body 3. It ’s fine. However, the number is four each, but the number is not limited to this number. In short, it is sufficient that the number is three or more.
However, the compression springs 31, 31 a, 34, 34 a, etc. should not hinder the fine movement of the tool mounting part 2 during processing.

次に、本発明に係る自動調芯工具ホルダーの作用について説明する。
工具T側が回転する場合、工作機F側の回転中心及びワークW側の孔Hの位置は加工時に常に同位置であるが、工作機F側の回転中心(装着部位本体3の中心軸軸)とワークWの孔(図示せず)の中心がズレたとしても、許容範囲内において、図10に示す様に、連動部材4の装着部位本体3及び工具取付部位2に対する2方向へのスライドにより、ズレた状態のまま工具取付部位2側へ回転を連動させることが可能になる。
ワークW側が回転する場合、装着部位本体3の中心軸及びワークWの回転中心の位置は加工時に常に同位置であるが、ワークWの回転中心に対しワークWの孔(図示せず)の中心がズレて加工時に円運動してしまっても、許容範囲内において、図11に示す様に、工具取付部位2に対する連動部材4及び工具取付部位2の直交方向へのスライドにより、ワークWの孔(図示せず)の円運動と同軌道で連動させることが可能になる。
Next, the operation of the self-aligning tool holder according to the present invention will be described.
When the tool T side rotates, the center of rotation on the machine tool F side and the position of the hole H on the workpiece W side are always the same during machining, but the rotation center on the machine tool F side (the central axis of the mounting part main body 3) Even if the center of the hole (not shown) of the workpiece W is displaced, within the allowable range, as shown in FIG. 10, by sliding in two directions with respect to the mounting part body 3 and the tool attachment part 2 of the interlocking member 4. It becomes possible to interlock the rotation to the tool mounting part 2 side in a shifted state.
When the work W side rotates, the position of the center axis of the mounting part main body 3 and the rotation center of the work W is always the same during processing, but the center of the hole (not shown) of the work W with respect to the rotation center of the work W As shown in FIG. 11, even if the disc is displaced and circularly moves at the time of machining, the interlocking member 4 with respect to the tool mounting portion 2 and the tool mounting portion 2 slide in the orthogonal direction as shown in FIG. It is possible to make it interlock with the circular motion (not shown) in the same orbit.

特に、工具Tをタップとし、ねじ切り加工を行う場合、タップは、切刃が自進作用の役目を行い強制的なねじ運動を必要としないことから、図8に示す様に、加工時におけるワークW又は工作機Fのタップ1回転分の送りをタップのピッチより僅かに短く設定すれば、ワークWに対しタップが自進するのに伴い工具取付部位2が不足分を補うべく引き出される、即ち自動調芯工具ホルダー自体が徐々に伸長し、それに伴い圧縮バネ16が徐々に圧縮される。   In particular, when tapping with the tool T as a tap, the tapping blade serves as a self-advancing action and does not require forced screw movement. Therefore, as shown in FIG. If the feed for one tap rotation of W or the machine tool F is set slightly shorter than the pitch of the tap, the tool mounting part 2 is pulled out to compensate for the shortage as the tap advances with respect to the workpiece W. The self-aligning tool holder itself is gradually extended, and the compression spring 16 is gradually compressed accordingly.

又、圧縮バネ16が工具取付部位2側のバネ受け部15に直接当接していると、装着部位本体3に対する工具取付部位2のスライドにより圧縮バネ16の後端部が工具取付部位2のスライド方向に振られる様に変形してしまうが、第2実施例の自動調芯工具ホルダーにあっては、図6に示す様に、圧縮バネ16によりバネ受け部15を押圧しつつ、圧縮バネ16を変形させずに工具取付部位2だけを装着部位本体3に対しスライドさせることが可能になる。   Further, when the compression spring 16 is in direct contact with the spring receiving portion 15 on the tool attachment portion 2 side, the rear end portion of the compression spring 16 slides on the tool attachment portion 2 due to the slide of the tool attachment portion 2 with respect to the attachment portion main body 3. However, in the self-aligning tool holder of the second embodiment, the compression spring 16 is pressed while pressing the spring receiving portion 15 with the compression spring 16 as shown in FIG. It is possible to slide only the tool attachment part 2 with respect to the attachment part main body 3 without deforming.

第3実施例にあっては、カバー21によりスライド突起7、7a、10、10a 及びスライド溝9、9a、14、14a が外部露出せず、該スライド突起7、7a、10、10a 及びスライド溝9、9a、14、14a に切粉、切屑が付着せず、更に鍔部23及び閉鎖リング25により、加工中であっても圧縮バネ26により閉鎖リング25が鍔部23に密着状態で、カバー21と連動部材4及び装着部位本体3の間の隙間22を完全に閉鎖することが可能になり、切粉、切屑の侵入を完全に阻止出来る。   In the third embodiment, the slide protrusions 7, 7a, 10, 10a and the slide grooves 9, 9a, 14, 14a are not exposed to the outside by the cover 21, and the slide protrusions 7, 7a, 10, 10a and the slide grooves are not exposed. 9, 9a, 14, 14a do not adhere to chips or chips, and the cover 23 and the closing ring 25 allow the closing ring 25 to be in close contact with the flange 23 by the compression spring 26 even during processing. It is possible to completely close the gap 22 between the interlocking member 4 and the attachment part main body 3, and it is possible to completely prevent chips and chips from entering.

第4実施例にあっては、圧縮状態の圧縮バネ31、31a …、34、34a …により押圧体32、32a …、35、35a …を、工具取付部位2の軸部13の外周面に当接させることで、外力が作用しない状態において上記軸部13を挿通孔5の中央に位置させると共に、軸部13が動く際にも常に軸部13の外周面に当接させた状態を維持する様にし、而も連動部材4及び装着部位本体3の両方に設けることで、軸部13を装着部位1の中心軸に対し常に平行状態を維持し易くなり、更に連動部材4及び装着部位本体3で位置を変えることで更に維持し易くなる。   In the fourth embodiment, the pressing members 32, 32a,..., 35, 35a are applied to the outer peripheral surface of the shaft portion 13 of the tool mounting portion 2 by the compression springs 31, 31a,. By making contact, the shaft portion 13 is positioned in the center of the insertion hole 5 in a state where no external force is applied, and the state where the shaft portion 13 is always in contact with the outer peripheral surface of the shaft portion 13 is maintained even when the shaft portion 13 moves. Similarly, by providing both the interlocking member 4 and the mounting part main body 3, it becomes easy to always maintain the shaft portion 13 parallel to the central axis of the mounting part 1, and further, the interlocking member 4 and the mounting part main body 3. It becomes easier to maintain by changing the position.

尚、工具取付部位2の頭部12の後面、連動部材4の前後面及び装着部位本体3の前面は、容易にスライド可能な様に、摩擦抵抗を低くする様に加工するか、スラスト軸受を介設するのが好ましい。   The rear surface of the head 12 of the tool mounting part 2, the front and rear surfaces of the interlocking member 4, and the front surface of the mounting part main body 3 are processed so as to reduce frictional resistance so that they can be easily slid, or a thrust bearing is provided. It is preferable to intervene.

又、本発明に係る自動調芯工具ホルダーは、工作機F側に対し着脱可能にするか、或いは工作機Fに直接組み込むか、いずれの形態であっても良い。   Further, the automatic alignment tool holder according to the present invention may be either detachable from the machine tool F side or directly incorporated into the machine tool F.
