Description

本発明は、工具を使用することなく工作機械に対する脱着を可能にした、ワークを支持するための脱着式ワーク仮受に関する。 The present invention relates to a removable work temporary receiver for supporting a work, which enables attachment / detachment to a machine tool without using a tool.

工作機械は、加工時にワークを回転支持する構成として、主軸台に対して心押台を有するものがある。そうした工作機械は、主軸に組み付けられた主軸チャックによってワークが保持され、そのワークに対して主軸チャックとは反対側から回転中心に心押台側のセンタが押し当てられる。両端が軸方向に支持されたワークは、主軸と中心を一致させた状態で回転が与えられ、そこにバイトが当てられる旋削加工などが行われる。こうして加工が行われるワークは軸方向に長いものが多く、センタによる押え込みの際にワークを支持するワーク仮受が使用される。下記特許文献１には、昇降シリンダによってＶ型ブロックを昇降させてワークを支持するようにした支持台が開示されている。 Some machine tools have a tailstock with respect to the headstock as a configuration for rotating and supporting the work during machining. In such a machine tool, a work is held by a spindle chuck assembled to the spindle, and a center on the tailstock side is pressed against the work from the side opposite to the spindle chuck to the center of rotation. The work whose both ends are supported in the axial direction is given rotation in a state where the spindle and the center are aligned with each other, and turning is performed in which a cutting tool is applied to the work. Many of the workpieces processed in this way are long in the axial direction, and a temporary workpiece receiver that supports the workpiece when pressed by the center is used. Patent Document 1 below discloses a support base in which a V-shaped block is raised and lowered by an elevating cylinder to support a work.

特開平７−６８４０２号公報Japanese Unexamined Patent Publication No. 7-68402

従来例として挙げた前記特許文献１の支持台は、構造が複雑であって大型でもあるため、それ自体にコストがかかってしまう。また、加工個所に位置したままであるため、バイトによってワークから発生する長くのびた切屑などが絡み付いてしまう。そのため、ワーク仮受の構成を簡単にしてコストを抑え、切屑の絡みつきを無くすためにも、加工前に簡単に脱着できるようなワーク仮受が望まれる。 Since the support base of Patent Document 1 given as a conventional example has a complicated structure and is also large in size, it is costly in itself. In addition, since it remains located at the processing site, long chips and the like generated from the work by the cutting tool are entangled. Therefore, in order to simplify the structure of the work temporary receiver, reduce the cost, and eliminate the entanglement of chips, it is desired to have a work temporary receiver that can be easily attached and detached before processing.

そこで、本発明は、かかる課題を解決すべく、工具を使用せずに工作機械に対する脱着を可能にする脱着式ワーク仮受を提供することを目的とする。 Therefore, an object of the present invention is to provide a removable work temporary receiver that enables attachment / detachment to a machine tool without using a tool in order to solve such a problem.

本発明に係る脱着式ワーク仮受は、鉛直な面に構成された工作機械の取付け部に対して上方から掛けるように取り付ける脱着部が一端部に形成され、前記工作機械の取付け部に対する脱着部の取り付けにより水平方向の姿勢が維持される棒状の支持部材と、前記支持部材に対して直交するように前記脱着側端部とは反対の先端部に設けられ、ワークに下から当てられるワーク受部の位置を上下させる可変機構を有するワーク受部材とを有する。 In the removable work temporary receiver according to the present invention, a detachable portion is formed at one end so as to be hung from above with respect to the attachment portion of the machine tool configured on a vertical surface, and the detachable portion with respect to the attachment portion of the machine tool. A rod-shaped support member whose horizontal posture is maintained by the attachment of the support member, and a work receiver provided at the tip opposite to the detachable end so as to be orthogonal to the support member and applied to the work from below. It has a work receiving member having a variable mechanism for raising and lowering the position of the portion.

前記構成によれば、棒状の支持部材に直交するワーク受部材によってワークを支持する場合、工具を使用することなく、工作機械の取付け部に対して脱着部を上方から掛けるようにして簡単に取り付けることができ、可変機構によってワーク受部を下降させることによりワークと干渉することなく簡単に取外すことができる。 According to the above configuration, when the work is supported by the work receiving member orthogonal to the rod-shaped support member, the work can be easily attached by hanging the detachable portion on the attachment portion of the machine tool from above without using a tool. By lowering the work receiving portion by the variable mechanism, it can be easily removed without interfering with the work.

本発明に係る脱着式ワーク仮受の一実施形態について、図面を参照しながら以下に説明する。例えば旋盤のような工作機械は、回転させたワークに対して切削工具を当てた旋削加工が行われる。そうした工作機械は、ベース上に主軸台が設けられ、主軸チャックによってワークが回転可能に保持される。その際、ワークの形状が回転軸方向に短い円盤状のようなものであれば主軸チャックによって把持するだけでよいが、回転軸方向に長い棒状のワークは、主軸チャックのクランプだけでは加工時の姿勢が維持できない。そこで、主軸チャックの反対側からもワークを支持する心押台が利用される。 An embodiment of the removable work temporary receiving according to the present invention will be described below with reference to the drawings. For example, in a machine tool such as a lathe, turning is performed by applying a cutting tool to a rotated workpiece. In such a machine tool, a spindle base is provided on the base, and the workpiece is rotatably held by the spindle chuck. At that time, if the shape of the work is like a disk that is short in the rotation axis direction, it is sufficient to grip it with the spindle chuck, but for a rod-shaped work that is long in the rotation axis direction, the clamp of the spindle chuck alone is sufficient for machining. I can't maintain my posture. Therefore, a tailstock that supports the work from the opposite side of the spindle chuck is also used.

図１及び図２は、心押台を利用した工作機械のワーク保持部の側面図であり、形態を変化させた本実施形態の脱着式ワーク仮受が各々に示されている。工作機械は、主軸に対峙するようにして心押台１が設けられ、主軸チャック３の中心に取り付けられたセンタ４と、心押台１のセンタ２とが主軸の回転軸と同軸上に位置している。そこで、切削加工の際には、ワークＷが両センタ２，４に挟み込まれるようにして支持される。 1 and 2 are side views of a work holding portion of a machine tool using a tailstock, and each of them shows a removable work temporary receiver of the present embodiment in which the form is changed. In the machine tool, the tailstock 1 is provided so as to face the spindle, and the center 4 attached to the center of the spindle chuck 3 and the center 2 of the tailstock 1 are positioned coaxially with the rotation axis of the spindle. doing. Therefore, during cutting, the work W is supported so as to be sandwiched between the centers 2 and 4.

ところで、心押台１を利用したワークＷの取付けにはワーク仮受が使用される。心押台１のセンタ２をワークＷの先端部に当てるまでの間、ワークＷを横向きにしたまま維持するためである。本実施形態の脱着式ワーク仮受（以下、単に「ワーク仮受」という）５は、心押台１側の鉛直な壁面１０１に対して脱着可能なＬ字形をしたものである。特に、工作機械には壁面１０１に取付け部が構成され、ワーク仮受５は、そこに工具を使用することなく脱着することが可能な構成となっている。 By the way, a work temporary receiver is used for attaching the work W using the tailstock 1. This is to keep the work W sideways until the center 2 of the tailstock 1 hits the tip of the work W. The removable work temporary receiver (hereinafter, simply referred to as “work temporary receiver”) 5 of the present embodiment has an L-shape that can be attached to and detached from the vertical wall surface 101 on the tailstock 1 side. In particular, the machine tool has a mounting portion on the wall surface 101, and the work temporary receiver 5 has a configuration in which it can be attached and detached without using a tool.

工作機械の取付け部は、支点ピン１０３を備えた厚板の脱着用固定板１０２が固定されている。具体的には、壁面１０１にタップが切られ、そのネジ穴にボルトを締め付けることによって脱着用固定板１０２が固定されている。ワーク仮受５は、そうした壁面１０１に対して直交する水平方向に延びる支持部材１１と、その支持部材１１に直交して上下方向に取り付けられるワーク受部材１２とを有している。 A thick plate detachable fixing plate 102 provided with a fulcrum pin 103 is fixed to the mounting portion of the machine tool. Specifically, a tap is cut on the wall surface 101, and the detachable fixing plate 102 is fixed by tightening a bolt in the screw hole. The work temporary receiver 5 has a support member 11 extending in the horizontal direction orthogonal to the wall surface 101, and a work receiving member 12 attached in the vertical direction orthogonal to the support member 11.

支持部材１１は、円筒状の棒材であり、その一端に脱着プレート２１が接合されている。図３は、支持部材１１の軸方向から示した脱着プレート２１の正面図である。脱着プレート２１は、支点ピン１０３に引掛けられるように、引掛け孔２１１が形成されている。引掛け孔２１１は、下側が支点ピン１０３のヘッド１０３ａより大きく、上部にかけて幅が小さくなるようにした滴形をしている。よって、ワーク仮受５は、引掛け孔２１１に入った支点ピン１０３に引掛けられ、脱着プレート２１が支持ピン１０３と壁面１０１とによってモーメントを受けるようにして、図１及び図２に示すような片持ち支持の状態で取付けられる。 The support member 11 is a cylindrical rod, and a detachable plate 21 is joined to one end thereof. FIG. 3 is a front view of the detachable plate 21 shown from the axial direction of the support member 11. The detachable plate 21 is formed with a hook hole 211 so as to be hooked on the fulcrum pin 103. The hook hole 211 has a drop shape in which the lower side is larger than the head 103a of the fulcrum pin 103 and the width becomes smaller toward the upper side. Therefore, the work temporary receiver 5 is hooked on the fulcrum pin 103 that has entered the hook hole 211, and the detachable plate 21 receives a moment by the support pin 103 and the wall surface 101, as shown in FIGS. 1 and 2. It can be installed in a cantilevered state.

次に、図４は、支持部材１１の先端部に設けられたワーク受部材１２を示した断面図であり、図５は、支持部材１１の軸方向から示したワーク受部材１２の正面図である。ワーク受部材１２は、細長形状の第１プレート２３と第２プレート２４が上下に連結されている。上側の第２プレート２４は、上端部にワークＷを受けるようにＶ字形のワーク受部２４１が形成され、下端部側に第１プレート２３が連結されている。第２プレート２４の下部裏面には、長手方向に沿って溝部２４２が形成され、その溝部２４２に重ねて長孔２４３が２箇所に形成されている。 Next, FIG. 4 is a cross-sectional view showing a work receiving member 12 provided at the tip of the support member 11, and FIG. 5 is a front view of the work receiving member 12 shown from the axial direction of the support member 11. is there. In the work receiving member 12, the elongated first plate 23 and the second plate 24 are vertically connected to each other. On the upper second plate 24, a V-shaped work receiving portion 241 is formed so as to receive the work W at the upper end portion, and the first plate 23 is connected to the lower end portion side. Grooves 242 are formed along the longitudinal direction on the lower back surface of the second plate 24, and elongated holes 243 are formed in two places so as to overlap the groove 242.

一方、第１プレート２３は、溝部２４２への嵌め合わせが可能な上部２３１が形成され、そこには長孔２４３に対応するようにネジ穴が形成されている。第１プレート２３と第２プレート２４は、長孔２４３を通した六角穴付きのボルト２５をワッシャを介してネジ穴へ締め付けることにより一体に固定され、締め付けを緩めることにより、第１プレート２３に対して溝部２４２に沿った方向、つまり長孔２４３の長手方向に第２プレート２４をずらした位置調整が可能になっている。 On the other hand, the first plate 23 is formed with an upper portion 231 that can be fitted into the groove portion 242, and a screw hole is formed therein so as to correspond to the elongated hole 243. The first plate 23 and the second plate 24 are integrally fixed by tightening a hexagon socket head cap screw 25 through a long hole 243 to a screw hole via a washer, and loosening the tightening to the first plate 23. On the other hand, the position of the second plate 24 can be adjusted by shifting it in the direction along the groove 242, that is, in the longitudinal direction of the elongated hole 243.

第１プレート２３は、その前側に突き立てられるように保持用凸部２６が接合されている。その保持用凸部２６にはタップが切られ、調整ボルト２７が下から突き抜けるようにして螺合している。また、その調整ボルト２７にはナット２８が螺合され、保持用凸部２６の下面に押し当てるナット２８の締め付けにより、保持用凸部２６に対する調整ボルト２７の位置決めが行われるようになっている。 The holding convex portion 26 is joined to the first plate 23 so as to be projected toward the front side thereof. A tap is cut on the holding convex portion 26, and the adjusting bolt 27 is screwed so as to penetrate from below. Further, a nut 28 is screwed into the adjusting bolt 27, and the adjusting bolt 27 is positioned with respect to the holding convex portion 26 by tightening the nut 28 that is pressed against the lower surface of the holding convex portion 26. ..

第２プレート２４の下端には前側に突き出した受側凸部２４４が形成され、保持用凸部２６から上方に突き出した調整ボルト２７の先端が下から突き当てられるようになっている。従って、保持用凸部２６から上方に突き出した調整ボルト２７について、その突出量を調整することにより、先端に当てられた受側凸部２４４の位置をずらすことができ、第２プレート２４のワーク受部２４１について微妙な位置調整が可能になっている。 A receiving-side convex portion 244 protruding forward is formed at the lower end of the second plate 24, and the tip of the adjusting bolt 27 protruding upward from the holding convex portion 26 is abutted from below. Therefore, by adjusting the amount of protrusion of the adjusting bolt 27 protruding upward from the holding convex portion 26, the position of the receiving side convex portion 244 applied to the tip can be shifted, and the work of the second plate 24 can be displaced. The position of the receiving portion 241 can be finely adjusted.

第１プレート２３は、溝部２４２の幅寸法に合わせた上部２３１と、それよりも大きい幅寸法の中間部２３２と、幅寸法を小さくした下部２３３とを有する形状となっている。第１プレート２３は、第２プレート２４の溝部２４２に上部２３１が対応し、前述したように長手方向の位置調整が可能な構成となっている。また、ワーク仮受５は、図１及び図２（図５（ａ）お及び図５（ｂ））に示すように、ワーク受部材１２の位置を支持部材１１に対して上下させることが可能な可変機構が構成されている。 The first plate 23 has a shape having an upper portion 231 that matches the width dimension of the groove portion 242, an intermediate portion 232 that has a larger width dimension, and a lower portion 233 that has a smaller width dimension. The upper portion 231 of the first plate 23 corresponds to the groove portion 242 of the second plate 24, and the position can be adjusted in the longitudinal direction as described above. Further, as shown in FIGS. 1 and 2 (FIGS. 5 (a) and 5 (b)), the work temporary receiver 5 can move the position of the work receiving member 12 up and down with respect to the support member 11. Variable mechanism is configured.

支持部材１１の先端には取付けプレート３１が接合され、そこにガイドブロック３２がボルト３４によって固定されている。図６は、そのガイドブロック３２を示した正面図である。ガイドブロック３２は、裏側にガイド溝３２１が形成され、取付けプレート３１に重ね合わせることにより、第１プレート２３の中間部２３２が上下方向にスライド可能な矩形断面の貫通孔が形成される。また、ガイドブロック３２には、取付けプレート３１に固定するためのボルト３４を通す長孔３２２が形成されている。長孔３２２は横方向に長いものであり、支持部材１１に対してワーク受部材１２の位置を横方向に調整できるようになっている。更に、ガイド溝３２１の範囲に重なるようにストッパ３３を取り付けるためのネジ孔３２３が形成されている。 A mounting plate 31 is joined to the tip of the support member 11, and a guide block 32 is fixed thereto by bolts 34. FIG. 6 is a front view showing the guide block 32. A guide groove 321 is formed on the back side of the guide block 32, and by superimposing it on the mounting plate 31, a through hole having a rectangular cross section is formed in which the intermediate portion 232 of the first plate 23 can slide in the vertical direction. Further, the guide block 32 is formed with an elongated hole 322 through which a bolt 34 for fixing to the mounting plate 31 is passed. The elongated hole 322 is long in the lateral direction, and the position of the work receiving member 12 can be adjusted in the lateral direction with respect to the support member 11. Further, a screw hole 323 for attaching the stopper 33 is formed so as to overlap the range of the guide groove 321.

ワーク仮受５は、ワーク受部材１２を上下方向にスライドさせることにより、上昇した図１（図５（ａ））の仮受位置と、下降した図２（図５（ｂ））の退避位置とに形態を変化させることが可能になっている。そこで、ワーク受部材１２の仮受状態を維持するため、ガイドブロック３２には２つのストッパ３３が取り付けられている。ストッパ３３は、インデックスプランジャであり、第１プレート２３の下部２３３の幅寸法に対応して２箇所に設けられ、中間部２３２の下端にピンが当たるように構成されている。従って、ストッパ３３のノブを手前に引くことによりピンが中間部２３２から外れ、第１プレート２３が仮受位置から退避位置へと下降するようになっている。 By sliding the work receiving member 12 in the vertical direction, the work temporary receiving 5 has a temporary receiving position in FIG. 1 (FIG. 5 (a)) that has been raised and a retracted position in FIG. 2 (FIG. 5 (b)) that has been lowered. It is possible to change the form. Therefore, in order to maintain the temporarily receiving state of the work receiving member 12, two stoppers 33 are attached to the guide block 32. The stoppers 33 are index plungers, which are provided at two locations corresponding to the width dimension of the lower portion 233 of the first plate 23, and are configured so that the pin hits the lower end of the intermediate portion 232. Therefore, by pulling the knob of the stopper 33 toward you, the pin comes off from the intermediate portion 232, and the first plate 23 descends from the temporary receiving position to the retracted position.

ワーク受部材１２は、調整ボルト２７がガイドブロック３２に当たることにより、所定の位置で下降が止められるようになっている。調整ボルト２７がガイドブロック３２に当たった位置がワーク受部材１２の退避位置である。そして、スライド可能なワーク受部材１２は、上下が逆転してもガイドブロック３２から抜け落ちないように、第１プレート２３の下部２３３に形成されたネジ孔に抜止めボルト３５が螺合している。 The work receiving member 12 is adapted to be stopped at a predetermined position by the adjusting bolt 27 hitting the guide block 32. The position where the adjusting bolt 27 hits the guide block 32 is the retracted position of the work receiving member 12. Then, the retaining bolt 35 is screwed into the screw hole formed in the lower 233 of the first plate 23 so that the slidable work receiving member 12 does not fall out of the guide block 32 even if it is turned upside down. ..

続いて、本実施形態のワーク仮受５は、次のようにして使用される。先ず、ワークＷは、一端部が主軸チャック３側のセンタ４に嵌め込まれ、他端部側が壁面１０１に取り付けられたワーク仮受５によって下から支えられて横向きの姿勢が維持される。心押台１のセンタ２が押し出されると、ワークＷは、図１に示すように両端から回転可能に支持される。ワーク仮受５は、両センタ２，４に挟み込まれるようにして支持されたワークＷの切削加工前には取り外される。図２に示すようにワーク受部材１２を退避位置まで下げることにより、加工時のワークＷとの干渉を避けることはできるが、長くのびる切屑が絡み付くなどの不具合が生じるからである。 Subsequently, the work provisional receiver 5 of the present embodiment is used as follows. First, one end of the work W is fitted into the center 4 on the spindle chuck 3 side, and the other end side is supported from below by the work temporary receiver 5 attached to the wall surface 101 to maintain a lateral posture. When the center 2 of the tailstock 1 is pushed out, the work W is rotatably supported from both ends as shown in FIG. The work temporary receiver 5 is removed before cutting the work W supported so as to be sandwiched between the centers 2 and 4. By lowering the work receiving member 12 to the retracted position as shown in FIG. 2, it is possible to avoid interference with the work W during machining, but this is because problems such as entanglement of long chips are caused.

ワーク仮受５は、工作機械に対する脱着が行われるため、その取扱いが容易であることが必要である。この点、ワーク仮受５は工具を使用することなく脱着することができる。先ず、ワーク仮受５を装着する場合には、脱着用固定板１０２の支点ピン１０３に対して、その支点ピン１０３が引掛け孔２１１に入れられ、図３の矢印で示すようにヘッド１０３ａを相対的に移動することにより、脱着プレート２１が支点ピン１０３に上方から引っ掛けられる。このときワーク仮受５は、支持部材１１が水平方向に延び、その先端ではワーク受部材１２が図１（図５（ａ））に示すように上方に向けて突き立てられている。 Since the work temporary receiver 5 is attached to and detached from the machine tool, it needs to be easy to handle. In this respect, the work temporary receiver 5 can be attached and detached without using a tool. First, when the work temporary receiver 5 is attached, the fulcrum pin 103 is inserted into the hook hole 211 with respect to the fulcrum pin 103 of the detachable fixing plate 102, and the head 103a is inserted as shown by the arrow in FIG. By moving relative to each other, the detachable plate 21 is hooked on the fulcrum pin 103 from above. At this time, in the work temporary receiver 5, the support member 11 extends in the horizontal direction, and the work receiving member 12 is thrust upward at the tip thereof as shown in FIG. 1 (FIG. 5A).

装着されたワーク受部材１２は、ストッパ３３のピンに支えられ、ワークＷを支持することが可能な仮受状態になっている。そして、調整ボルト２７を使用したワーク受部２４１の微調整が行われる。このときボルト２５が緩められた状態で、例えば調整ボルト２７が保持用凸部２６のネジ孔に締め込まれることにより棒先が上昇し、受側凸部２４４を介して第２プレート２４が押し上げられ、長孔２４３の範囲内で位置調整が行われる。 The mounted work receiving member 12 is supported by the pin of the stopper 33 and is in a temporarily receiving state capable of supporting the work W. Then, the work receiving portion 241 is finely adjusted using the adjusting bolt 27. At this time, with the bolt 25 loosened, for example, the adjusting bolt 27 is tightened into the screw hole of the holding convex portion 26, so that the rod tip rises and the second plate 24 is pushed up via the receiving side convex portion 244. The position is adjusted within the range of the elongated hole 243.

一方、ワーク仮受５を取外す場合は、既にワークＷが心押台１によって主軸チャック３との間にセットされているため、図１の状態のままでは支点ピン１０３に引っ掛けられた脱着プレート２１を上方に持ち上げて外すことはできない。そこで、ワーク仮受５の取外しを可能にするため、ワーク受部材１２が図２（図５（ｂ））に示す退避位置に下げた形態に変えられる。その変形にはインデックスプランジャであるストッパ３３のノブが手前側に引かれる。すると、ピンから外れた第１プレート２３がガイドブロック３２内を下降し、調整ボルト２７がガイドブロック３２に突き当てられて止まる。ワーク仮受５は、ワークＷとの干渉が無くなるため、上方に持ち上げられて脱着プレート２１が支点ピン１０３から外れ、ワークＷの加工箇所からワーク仮受５が取り除かれる。 On the other hand, when the work temporary receiver 5 is removed, since the work W has already been set between the work W and the spindle chuck 3 by the tailstock 1, the detachable plate 21 hooked on the fulcrum pin 103 remains in the state of FIG. Cannot be lifted up and removed. Therefore, in order to enable the temporary work receiving 5 to be removed, the work receiving member 12 can be changed to a form in which the work receiving member 12 is lowered to the retracted position shown in FIG. 2 (FIG. 5 (b)). The knob of the stopper 33, which is an index plunger, is pulled toward the front side for the deformation. Then, the first plate 23 that has come off the pin descends in the guide block 32, and the adjusting bolt 27 is abutted against the guide block 32 and stops. Since the work temporary receiver 5 eliminates interference with the work W, the work temporary receiver 5 is lifted upward and the detachable plate 21 is disengaged from the fulcrum pin 103, and the work temporary receiver 5 is removed from the processed portion of the work W.

よって、本実施形態のワーク仮受５は、支点ピン１０３に脱着プレート２１を引っ掛けるだけで取り付けることができ、工具を使用することなく工作機械に対する脱着が可能であるため、心押台１を使用した加工前の作業が非常に簡単なものとなる。また、ワーク仮受５を取外す際には、ストッパ３３のノブを手前側に引くことだけで、ワーク受部材１２を退避位置に下降させることができる。一方、仮受位置のワーク受部材１２は、調整ボルト２７によってワーク受部２４１の微調整を行うことが可能でるため、ワークＷを適切な位置で支持することができる。 Therefore, the work temporary receiver 5 of the present embodiment can be attached by simply hooking the attachment / detachment plate 21 on the fulcrum pin 103, and can be attached / detached to the machine tool without using a tool. Therefore, the tailstock 1 is used. The work before processing is very easy. Further, when removing the work temporary receiving member 5, the work receiving member 12 can be lowered to the retracted position only by pulling the knob of the stopper 33 toward the front side.
