Description

本発明は、加工物を固定して工作する工作機械で使用されるバイスの口金であり、加工物をバイスで挟持した時、バイスの挟持基準面から、加工物の浮き上がりを防止するバイスの口金に関するものである。 The present invention is a vise base used in a machine tool for fixing a workpiece to work, and when the workpiece is clamped by a vise, the vise base that prevents the workpiece from being lifted from the clamping reference plane of the vise It is about.

従来は、図１９に示すように、加工物２３をバイスの口金２２，口金２６に挟み、ネジ３１でスライド１９を押すと、加工物２３のスライド側底面と、正直台２５との間に隙間ｃが生じる。加工物のスライド側の上面を、木ハンマー等で叩いても隙間ｃは無くならない。この状態で加工物２３の上面を加工すると、加工物２３の上面と下面の厚みは、固定口金２２側とスライド口金２６側でcの差が生じるのが現状である。 Conventionally, as shown in FIG. 19, when the workpiece 23 is sandwiched between the vice base 22 and the base 26 and the slide 19 is pressed with the screw 31, there is a gap between the slide-side bottom surface of the workpiece 23 and the honest table 25. c occurs. Even if the upper surface of the workpiece on the slide side is hit with a wooden hammer or the like, the gap c does not disappear. When the upper surface of the workpiece 23 is machined in this state, the thickness of the upper surface and the lower surface of the workpiece 23 is currently different from c on the fixed base 22 side and the slide base 26 side.

加工物をバイスの挟持基準面に、確実に密着させて挟む方法として、クサビの原理を応用した機構をバイス本体に組み込んだものがある。しかし、従来のクサビ原理を応用した機構のものは、スライド側の、加工物に接触するクサビ形駒が厚くて重い。（公開実用新案昭６１−１９９３５６参照）
前記クサビ形駒の底面と、バイス本体のスライド摺動面との間に、隙間があり、切粉や、鉄紛等が入り、バイス本体の摺動面を傷つけ、その隙間は狭く、加工物の交換ごとの掃除が大変であった。 There is a method in which a mechanism that applies the wedge principle is incorporated in a vice body as a method for securely holding a workpiece to be in close contact with a clamping reference surface of the vice. However, in the mechanism using the conventional wedge principle, the wedge-shaped piece in contact with the workpiece on the slide side is thick and heavy. (See Public Utility Model Sho 61-199356)
There is a gap between the bottom surface of the wedge-shaped piece and the sliding sliding surface of the vice body, chips and iron powder enter, damage the sliding surface of the vise body, the clearance is narrow, the work piece Cleaning every replacement was difficult.

加工物を挟む時、前記クサビ形駒は、バイス本体の摺動面に接近するので、加工物を挟む前に、加工物を挟む以前の高さに、前記クサビ形駒を復帰させるのに、バネを使っている。そのバネの片方の端にあるバネピン等が、バイス本体のスライド摺動面に直接触れているので、スライドを動かす毎に、バネの端にあるピンがバイス本体のスライド摺動面をこする。バネの端にあるピンとバイス本体のスライド摺動面の間に鉄粉等が入り易く、スライド摺動面の磨耗を加速していた。 When the workpiece is sandwiched, the wedge-shaped piece approaches the sliding surface of the vice body, so that before the workpiece is sandwiched, the wedge-shaped piece is returned to the height before the workpiece is sandwiched. A spring is used. Since a spring pin or the like at one end of the spring directly touches the slide sliding surface of the vice body, the pin at the end of the spring rubs against the slide sliding surface of the vise body each time the slide is moved. Iron powder or the like is likely to enter between the pin at the end of the spring and the slide sliding surface of the vise body, accelerating wear of the sliding surface.

加工物を挟む前(フリーの状態)の高さに、前記クサビ形駒を復帰するのに、変心カムを使っているのもあるが、加工物を挟む時の操作が面倒である。（特開平９−１０８９６９参照）
バイスのスライドの加工物側を傾斜面に加工して、上記クサビ形駒を、直接取り付けた物や、クサビ形駒とクサビ形駒を取り付けるための駒をセットにし、スライドの加工物側を、前記セットの専用取り付け面に加工して取り付けていた物があるが、その取り付け方はそのバイス専用で、他のバイスには、簡単に付け替えが出来ない。（特開２００３−１８１７３２参照） An eccentric cam is used to return the wedge-shaped piece to the height before the workpiece is sandwiched (free state), but the operation when sandwiching the workpiece is troublesome. (See JP-A-9-108969)
Process the workpiece side of the vise slide into an inclined surface, set the above wedge-shaped piece directly attached or the piece for attaching the wedge-shaped piece and the wedge-shaped piece, set the workpiece side of the slide, There are things that have been processed and attached to the dedicated attachment surface of the set, but the attachment method is dedicated to that vice, and other devices cannot be easily replaced. (See JP2003-181732)

従来の、クサビの原理を応用したバイスは、口金が沈む機構用の傾斜面を持つ、スライド側の口金が、厚くて重く、復帰用のバネが接触する摺動面の磨耗が加速されていた。
加工物の取替え時、掃除に手間がかかり、操作も面倒でした。
又、口金の左右の動きを制御する機構や、加工物を挟んでない時、傾斜面を密着させる機構に対する研究があまりされていない。 The conventional vice applying the wedge principle has an inclined surface for the mechanism where the base sinks, the base on the slide side is thick and heavy, and the wear of the sliding surface with which the return spring contacts is accelerated. .
When replacing the workpiece, it took time to clean and the operation was cumbersome.
In addition, there has not been much research on a mechanism for controlling the left and right movement of the base and a mechanism for closely contacting the inclined surface when a workpiece is not sandwiched.

一般に使われているバイスの口金のように、薄くて軽い、コンパクトな機構のもので、新しいバイスや、長年使いこなした古いバイスでも、簡単に取り付けられる事が望まれていた。 It is a thin, light, and compact mechanism like a commonly used vise base, and it was desired that new vices and old ones that were used for many years could be easily installed.

本発明の直方体の口金は二分割からなる口金とし、その二分割方法は、二分割から成る口金の挟持物に接触する面を正面とし、側面視で、加工物に接触する側の口金の上端面を狭く、下端面を広くするように斜めに分割し、加工物側の口金を口金１、バイスに取り付けられる面側の口金を口金２、斜め分割面を傾斜面１０とする。 The rectangular parallelepiped base of the present invention is a base divided into two parts, and the two-part splitting method is such that the surface that contacts the sandwiched base of the base divided into two parts is the front surface, and the base on the side that comes into contact with the workpiece in a side view. The end face is narrowed and the lower end face is widened diagonally, the workpiece-side base is the base 1, the surface-side base attached to the vise is the base 2, and the diagonally divided surface is the inclined surface 10.

但し、口金１及び口金２は、各々別の直方体の材料から前記口金１、口金２の形状に成形しても良い。 However, the base 1 and the base 2 may be formed into the shapes of the base 1 and the base 2 from different rectangular parallelepiped materials.

口金１と口金２を合わせた大きさは、バイスの挟持面の耐磨耗性を向上させるため、バイスの挟持面に、従来、一般に取り付けられていた焼き入れ鋼板と、ほぼ同じ大きさにし、本発明の口金のバイスへの取り付けボルト穴の位置及び大きさは、従来のバイスメーカーの規格に合わせて加工した。 The combined size of the base 1 and the base 2 is approximately the same size as that of a hardened steel plate generally attached to the vice holding surface in order to improve the wear resistance of the holding surface of the vice. The position and size of the bolt holes for attaching the base of the present invention to the vise were processed according to the standards of the conventional vice maker.

バイスに挟持されていた加工物を口金から外したとき、加工物を挟持する以前の状態に、加工物側の口金１を自動復帰させるバネを、口金１と口金２の傾斜面側に、口金が摺動する方向の溝又は穴を設け、その溝又は穴に設置し、口金１の摺動ストローク量を制御するのに、段付きボルト又はピンを使った。 When the workpiece held by the vice is removed from the die, a spring that automatically returns the workpiece-side die 1 to the state before the workpiece is held is placed on the inclined surface side of the die 1 and the die 2. In order to control the amount of sliding stroke of the base 1, a stepped bolt or pin was used.

口金１の摺動案内に角形キー溝機構を使い、貫通キー溝にした。口金１と口金２の傾斜面を密着させる機構には、段付きボルトとバネを使用した。 A square keyway mechanism was used for sliding guide of the base 1 to form a through keyway. A stepped bolt and a spring were used as a mechanism for closely contacting the inclined surfaces of the base 1 and the base 2.

口金１の摺動案内と、口金１と口金２の傾斜面の密着させる機構に、アリ形やＴ溝形の機構もつかえる。 The sliding guide of the base 1 and the mechanism for bringing the inclined surfaces of the base 1 and the base 2 into close contact with each other can be replaced with an ant-shaped or T-groove type mechanism.

アリ形やＴ溝形の場合、アリ形やＴ形の凸形状を削り出して一体形にするのが一般的であるが、アリ形やＴ形の変形キーとして、取り付ける方法にした。 In the case of an ant shape or T-groove shape, it is common to cut out the ant shape or T-shaped convex shape to make it an integral shape, but the ant-shaped or T-shaped deformation key is attached.

前記バネの代わりに弾性体を使っても作用は同じである。 Even if an elastic body is used instead of the spring, the operation is the same.

バイスの挟持面に取り付けて一般に使われていた口金と、本発明の口金は、ほぼ同じ大きさで、同じ形であり、本発明の口金をバイスに取り付ける穴の位置及び大きさを、バイスメーカーの規格に合うように加工している為、加工物の浮き上がり防止機構内蔵の本発明の口金は、一般に使われていた一枚の直方体の口金と、簡単に交換して使える。
また、加工物を本発明の口金が付いたバイスに挟持する操作も、従来、一般に使われていた一枚の直方体の口金が付いているバイスの操作と同じで、簡単である。 The base generally used by attaching to the holding surface of the vice and the base of the present invention have almost the same size and the same shape, and the position and size of the hole for attaching the base of the present invention to the vice are specified by the vice manufacturer. Therefore, the base of the present invention with a built-in mechanism for preventing the workpiece from being lifted up can be used by simply replacing it with a generally used rectangular parallelepiped base.
In addition, the operation of holding the workpiece between the vise with the cap of the present invention is the same as the operation of the vise with a single rectangular parallelepiped cap that has been conventionally used, and is simple.

口金１の自動復帰用バネを、バイス本体の摺動面と全く関係の無い、口金１と口金２の傾斜面側に埋め込んだので、従来の浮き上がり防止機構の駒と比較すれば、本発明の口金は、コンパクトであり、しかも、バイス本体のスライド摺動面の掃除も楽になり、また、自動復帰用バネに依る、バイス本体のスライド摺動面の磨耗も無くなった。
口金１、口金２の摺動面に最も近い所にバネを設置したので、バネによる口金１の摺動が滑らかである。 Since the spring for automatic return of the base 1 is embedded on the inclined surface side of the base 1 and the base 2, which has nothing to do with the sliding surface of the vise body, the spring of the present invention is compared with the conventional lifting prevention piece. The base is compact, and it is easy to clean the sliding surface of the vice body, and wear of the sliding surface of the vice body due to the automatic return spring is eliminated.
Since the spring is installed at a position closest to the sliding surface of the base 1 and the base 2, the sliding of the base 1 by the spring is smooth.

段つきボルトにした事に依り、ボルトを完全にネジへ固定しても、バネの押す力を一定に出来る。口金１と口金２の傾斜面を、バネに依り、常に一定の圧力で密着させている為、口金１の摺動面に埃等が入らないので、口金１は滑らかに動き、本発明の口金の精度が長く保持される。 By using a stepped bolt, the spring pressing force can be kept constant even if the bolt is completely fixed to the screw. Since the inclined surfaces of the base 1 and the base 2 are always brought into close contact with each other with a constant pressure by a spring, dust or the like does not enter the sliding surface of the base 1, so that the base 1 moves smoothly and the base of the present invention is used. The accuracy of is kept long.

クサビ原理を応用した、従来のバイスに取り付けられている口金の両端の、つばの代わりに、（昭６１−１９９３５６参照）角形キーにした事に依り、口金１の傾斜面が単純な一つの面と成り、摺動面となる傾斜面の加工が容易で、熱処理後の研削加工も容易である。また、貫通キー溝にしたことに依り、キー溝の加工も容易で、熱処理後のキー溝の研削加工も容易である。また、口金の材料も小さくなる。故に、口金の精度向上と、加工コストの低減になる。 Applying the wedge principle, instead of the collars at both ends of the base attached to the conventional vise (see Sho 61-199356), the base 1 has a simple inclined surface due to the use of a square key. Thus, the inclined surface serving as the sliding surface can be easily processed, and grinding after the heat treatment is also easy. Further, since the through key groove is formed, the key groove can be easily processed, and the key groove after the heat treatment can be easily ground. In addition, the material of the base becomes small. Therefore, the precision of the die is improved and the processing cost is reduced.

傾斜面を高精度に加工出来ることに依り、口金１の傾斜面摺動抵抗が小さくすることが出来、故に、傾斜面の傾斜角度が小さくても、口金１が加工物を挟持した時、口金２の傾斜面による、スライドの挟持力の分力でスライドは、スライドあご板がバイスの摺動あごに当たるまで浮き上がって止まり、口金１はその反力で加工物を加工物取り付け基準面に押しつけることが出来るので、傾斜面の角度を小さくして、口金全体の厚みを薄くすることが出来る。 Due to the fact that the inclined surface can be machined with high accuracy, the sliding resistance of the inclined surface of the base 1 can be reduced. Therefore, even when the inclined angle of the inclined surface is small, when the base 1 clamps the workpiece, The slide is lifted and stopped until the slide jaw plate hits the sliding jaw of the vise, and the base 1 presses the workpiece against the workpiece mounting reference surface by the reaction force. Therefore, the angle of the inclined surface can be reduced, and the thickness of the entire die can be reduced.

ピンが、口金１の摺動長さを制御しているので、一定のバネの圧力で、口金１を最大ストロークの位置に摺動させる。本発明の口金が加工物を挟持してなくても口金１と口金２の摺動を制御しているので、安定して口金を取り扱える。 Since the pin controls the sliding length of the base 1, the base 1 is slid to the position of the maximum stroke with a constant spring pressure. Even if the base of the present invention does not hold the workpiece, the base 1 and the base 2 are controlled to slide, so that the base can be handled stably.

アリ形やＴ形の凸形状は、削り出すのが一般的であるが、アリ形やＴ形の凸形状を、アリ形やＴ形の変形キーとして組付ける方法にしたことに依り、口金１１の傾斜面の形状が凸部の無い一つの面になり、傾斜面の加工が容易になって、熱処理後の研削加工も容易になり、口金1１の摺動面精度も向上し、加工コストも安くなる。また、変形キーの摺動面の研削加工も容易になり。口金の材料も小さくなり加工コストの低減になる。 The ant-shaped or T-shaped convex shape is generally cut out, but the base 11 depends on the method of assembling the ant-shaped or T-shaped convex shape as an ant-shaped or T-shaped deformation key. The shape of the inclined surface becomes a single surface with no protrusions, which makes it easy to process the inclined surface, facilitates grinding after heat treatment, improves the sliding surface accuracy of the base 11, and reduces the processing cost. Become cheap. In addition, it is easy to grind the sliding surface of the deformation key. The material of the die is also reduced, and the processing cost is reduced.

本発明の口金は、加工物を挟むバイスの口金以外にも、大きな加工物で、バイスで挟めず、直接工作機械のテーブルに固定する時使用される、ソリッドバイス等の挟持装置の口金にも使用できる。又、小型にすれば、旋盤で使用するチャックの挟持部の口金にも使用できる。 The base of the present invention is not only a base of a vice that sandwiches a workpiece, but also a base of a clamping device such as a solid vise that is a large workpiece and is used when directly fixing to a machine tool table without being sandwiched by a vice. Can be used. Moreover, if it is made small, it can also be used for a cap of a chucking portion used in a lathe.

本発明の実施形態１を図1から図４に基づいて説明する。 A first embodiment of the present invention will be described with reference to FIGS.

実施形態１の直方体の口金は二分割からなる口金とし、その二分割方法は、二分割から成る口金の挟持物に接触する面を正面とし、側面視で、加工物に接触する側の口金の上端面を狭く、下端面を広くするように斜めに分割し、加工物側の口金を口金１、バイスに取り付けられる面側の口金を口金２、斜め分割面を傾斜面１０とする。 The rectangular parallelepiped base of Embodiment 1 is a base divided into two parts, and the two-part dividing method has a front surface that is in contact with the sandwiched base of the base divided into two parts, and the side of the base that comes into contact with the workpiece in a side view. The upper end surface is narrowed and the lower end surface is widened diagonally, the workpiece-side base is the base 1, the surface-side base attached to the vise is the base 2, and the diagonally divided surface is the inclined surface 10.

図１の口金中央部Ａ−Ａ断面の位置に、図２に示す、段付きボルト取り付けネジ穴と段付きボルト取り付け座ぐり穴加工を口金１の中心に、傾斜面１０側から加工する。口金２の傾斜面１０側の反対側から、段付きボルト穴径に口金１のストローク量ａを加えた大きさの穴と段付きボルトの頭部用座ぐり穴径に口金１のストローク量ａを加えた大きさの穴を加工する。 A stepped bolt mounting screw hole and a stepped bolt mounting counterbore shown in FIG. 2 are processed from the inclined surface 10 side at the center of the base 1 at the position of the cross section AA of the base center portion of FIG. From the opposite side of the inclined surface 10 side of the base 2, a hole having a size obtained by adding the stroke amount “a” of the base 1 to the diameter of the stepped bolt hole, and a stroke amount “a” of the base 1 to the counterbore hole diameter for the head of the stepped bolt Process a hole with a size of.

図１のＢ−Ｂ断面の位置は、バイスメーカーの口金取り付けボルト穴の規格に合った位置であり、図３に示す様に、口金１の穴は、前記規格の座ぐり穴径で長穴とし、その長穴の値は、口金１の摺動ストローク量ａとする。口金２には、傾斜面１０側から前記規格の座ぐり穴とボルト穴を加工する。 The position of the B-B cross section in FIG. 1 is a position that meets the specifications of the base mounting bolt holes of the vice maker, and as shown in FIG. 3, the holes of the base 1 are oblong holes with the counterbore diameter of the standard. The value of the elongated hole is the sliding stroke amount a of the base 1. The base 2 is machined with a counterbore hole and a bolt hole of the standard from the inclined surface 10 side.

図１のＣ−Ｃ断面の位置には、図４に示す貫通キー溝を、傾斜面１０と平行な深さで、しかも、口金１の摺動方向（上下方向）に、口金１と口金２の傾斜面１０側に各々設ける。口金１はキー溝の上部の底面にキー１５の取り付けネジ穴、口金２にはキー溝の下部の底面にキー１４の取り付けネジ穴を設ける。
キー１４、キー１５は、各々キー取り付けボルト用穴を設け、片方の端面にバネ９を納める穴を設け、長さは、キー１４とキー１５の長さに口金１の摺動ストローク量ａを加えた長さを、キー溝の長さ以下にする。 In the position of the CC cross section in FIG. 1, the through key groove shown in FIG. 4 is formed at a depth parallel to the inclined surface 10 and in the sliding direction (vertical direction) of the base 1 and the base 2. Provided on the inclined surface 10 side. The base 1 is provided with an attaching screw hole for the key 15 on the bottom surface at the top of the key groove, and the base 2 is provided with an attaching screw hole for the key 14 on the bottom surface at the bottom of the key groove.
Each of the keys 14 and 15 is provided with a hole for a key mounting bolt, a hole for accommodating the spring 9 is provided on one end face, and the length of the key 14 and the key 15 is the length of the sliding stroke a of the base 1 to the length of the key 14 and the key 15. Make the added length less than the length of the keyway.

次に、口金１と口金２を組付ける方法は、口金１のキー溝の上部にキー１５を、バネ９を納める穴を下向きにして固定する。口金２のキー溝の下部にキー１４を、バネ９を納める穴を上向きにして固定する。キー１４のバネ９用穴にバネ９を入れ、口金１のキー溝の下部に口金２のキー１４を、口金１のキー１５の下部に口金２のキー溝を、それぞれ合わせ、口金１と口金２の段付きボルトの穴が一致するまで、口金２を上に押し上げ、（図２参照）口金２の段付きボルト頭用座ぐり穴に、バネ７を入れて、段付きボルトを口金１に取り付ける。 Next, the method of assembling the base 1 and the base 2 is to fix the key 15 on the upper part of the key groove of the base 1 with the hole for housing the spring 9 facing downward. The key 14 is fixed to the lower part of the keyway of the base 2 with the hole for accommodating the spring 9 facing upward. The spring 9 is inserted into the hole for the spring 9 of the key 14, the key 14 of the base 2 is aligned with the lower part of the key groove of the base 1, and the key groove of the base 2 is aligned with the lower part of the key 15 of the base 1. Push the base 2 up until the holes in the two stepped bolts are aligned (see Fig. 2), insert a spring 7 into the counterbore for the stepped bolt head of the base 2 and place the stepped bolt into the base 1 Install.

口金の作用について説明する。段付きボルト頭部用座ぐり穴に組み込まれたバネ７は、(図２参照)口金２の傾斜面１０を口金１の傾斜面１０に密着させている。また、口金２の段つきボルト穴及び段つきボルト頭部用座ぐりの大きさは、口金１のストローク量ａだけ大きくしてあるので、段付きボルトは、口金１の摺動ストローク量を制御している。 The operation of the base will be described. The spring 7 incorporated in the stepped bolt head counterbore (see FIG. 2) brings the inclined surface 10 of the base 2 into close contact with the inclined surface 10 of the base 1. Further, the size of the stepped bolt hole of the base 2 and the counterbore for the stepped bolt head is increased by the stroke amount a of the base 1, so the stepped bolt controls the sliding stroke amount of the base 1. ing.

口金１と口金２の傾斜面側のキー溝に固定されたキー１４，１５に組み込まれたバネ９に依り、口金１は段付きボルトが口金２に当たるまで、常に上へ押し上げられている。 Due to the springs 9 incorporated in the keys 14 and 15 fixed in the key grooves on the inclined surfaces of the base 1 and the base 2, the base 1 is always pushed up until the stepped bolt hits the base 2.

キー１４，１５は、口金１が傾斜面１０を摺動する方向に案内をしているので、口金１は摺動方向（上下方向）には滑らかに動くが、左右方向（横方向）の動きや、左右方向の捩れは無い。 The keys 14 and 15 guide the base 1 in the direction in which the base 1 slides on the inclined surface 10, so that the base 1 moves smoothly in the sliding direction (up and down direction) but moves in the left and right direction (lateral direction). There is no left-right twist.

実施形態１の口金をスライドに取り付ける為の口金１の穴は、口金１のストローク量ａ分長穴に加工されているので、口金１は、取り付けボルトに邪魔されること無く摺動できる。 Since the hole of the base 1 for attaching the base of the first embodiment to the slide is processed into a long hole corresponding to the stroke amount a of the base 1, the base 1 can slide without being obstructed by the mounting bolt.

実施形態１の口金をバイスに取り付けた状態の作用を図１８に基づいて説明する。
バイスのスライド側に付いていた従来の口金を外し、加工物側の口金１の上面が下面より狭くなる状態で、実施形態１の口金をスライドに取り付ける。正直台２４，２５を、固定側口金とスライド側の口金に各々接触させて、バイスの加工物取り付け基準面に置き、加工物２３を正直台の上に置く。 The operation of the first embodiment with the base attached to the vise will be described with reference to FIG.
The conventional base attached to the slide side of the vise is removed, and the base of the first embodiment is attached to the slide in a state where the upper surface of the base 1 on the workpiece side is narrower than the lower surface. The honest tables 24 and 25 are brought into contact with the fixed base and the slide base, respectively, and placed on the workpiece attachment reference surface of the vice, and the workpiece 23 is placed on the honest table.

ネジ３１のハンドル２８を右に回し、スライド１９を摺動させて、加工物２３をバイスに挟持させると、ネジ３１の押す力は、口金２の傾斜面により、口金１を水平に押す力と、垂直に上向きの力に分力される。上向きの力により、口金２はキーに案内されて真直ぐ上に押されるため、スライドの加工物側は浮き上がり、スライドあご板２９とバイスの摺動面のあご３０との隙間ｓがゼロに成るまで、スライドは浮き上がり止まる。故に、あご板２９はあご３０に密着する。また、口金２の上向きの力の反力で口金１は下に押される。口金１は加工物を水平方向に押しながら、下に押し続けるので、加工物２３は、底面を正直台に密着した状態で挟持され、浮き上がれない。 When the handle 28 of the screw 31 is turned to the right, the slide 19 is slid and the workpiece 23 is clamped between the vices, the pressing force of the screw 31 is such that the inclined surface of the base 2 pushes the base 1 horizontally. It is divided into vertical, upward force. Due to the upward force, the base 2 is guided straight by the key and pushed straight up, so that the workpiece side of the slide is lifted up until the gap s between the slide jaw plate 29 and the jaw 30 of the sliding surface of the vice becomes zero. The slide will float up and stop. Therefore, the jaw plate 29 is in close contact with the jaw 30. Also, the base 1 is pushed downward by the reaction force of the upward force of the base 2. Since the base 1 keeps pushing the work piece in the horizontal direction and keeps pushing down, the work piece 23 is sandwiched with the bottom face in close contact with the honest table and does not float up.

ネジ３１のハンドル２８を左に回し、ネジ３１の押す力を解除すると、スライド１９は自重で前記隙間ｓの距離だけ下がる。また、口金１は、口金１の傾斜面側のキー１５に設置されているバネ９に依り、加工物を挟持する前の状態（段付きボルトが口金２に当たった位置）に復帰する。 When the handle 28 of the screw 31 is turned counterclockwise and the pushing force of the screw 31 is released, the slide 19 is lowered by the distance of the gap s by its own weight. The base 1 returns to the state before the workpiece is clamped (position where the stepped bolt hits the base 2) by the spring 9 installed on the key 15 on the inclined surface side of the base 1.

挟持装置のスライド部を摺動させる動力は、ネジに限らず、油圧、空気圧でも同じ作用をする。 The power for sliding the sliding portion of the clamping device is not limited to the screw, and the same effect can be obtained by hydraulic pressure and pneumatic pressure.

本発明の口金は、従来の一般に使用されていたバイスの口金と形や大きさがほぼ同じであり、従来のクサビ原理を応用した機構の口金と比較するとコンパクトであり、口金をバイスに取り付ける穴のサイズや位置が、バイスメーカーの規格に合う様に製作してあるので、一般に使用されていたバイスの口金と簡単に交換して使用する事が出来る。 The base of the present invention is approximately the same in shape and size as a conventional vise base that is generally used, and is more compact than a base of a mechanism that uses a conventional wedge principle, and a hole that attaches the base to the vice. Since the size and position of the product is manufactured to meet the standards of the vice maker, it can be used by easily replacing the commonly used vice base.

口金１と口金２は常に密着して一体化しているので、本発明の口金を取り付けたバイスの操作方法は、一般に使用されていた従来の一枚の直方体の口金を取り付けたバイスの操作方法と同じで、簡単である。 Since the base 1 and the base 2 are always in close contact with each other, the operation method of the vise attached with the base of the present invention is the same as the operation method of the vise attached with a conventional one-piece rectangular parallelepiped base. Same and simple.

段付きボルトとバネの組み合わせに依り、口金１と口金２の摺動面は常に密着しているので、口金の摺動面精度保持が長い。 Depending on the combination of the stepped bolt and the spring, the sliding surfaces of the base 1 and the base 2 are always in close contact with each other, so that the precision of the sliding surface of the base is long.

角形キー機構を使用して傾斜面の形状を凸部の無い一つの面にし、しかも、貫通キー溝であるので、傾斜面及びキー溝の加工が容易である為、キー溝及び傾斜面の摺動面が安価で高精度に加工出来る。 Using a square key mechanism, the shape of the inclined surface is made one surface without a convex part, and since it is a penetrating key groove, it is easy to process the inclined surface and the key groove. The moving surface is inexpensive and can be machined with high precision.

傾斜面を高精度に加工出来ることに依り、口金１の傾斜面摺動抵抗を小さくすることが出来る。故に、傾斜面の傾斜角度が小さくても、口金１が加工物を挟持した時、口金２の傾斜面による、スライドの挟持力の分力でスライドは、スライドあご板がバイスの摺動あごに当たるまで浮き上がって止まり、口金１はその反力で加工物を加工物取り付け基準面に押しつけることが出来るので、傾斜面の角度を小さくして、口金全体の厚みを薄くすることが出来た。 Because the inclined surface can be processed with high accuracy, the sliding resistance of the inclined surface of the base 1 can be reduced. Therefore, even when the inclination angle of the inclined surface is small, when the base 1 clamps the work piece, the slide jaw plate hits the sliding jaw of the vise with the component of the holding force of the slide by the inclined surface of the base 2 Since the base 1 can press the workpiece against the workpiece mounting reference surface by the reaction force, the angle of the inclined surface can be reduced and the entire thickness of the base can be reduced.

口金１が加工物を挟持する以前の状態に、口金１を摺動させるバネ９を、バイス本体の摺動面と全く関係の無い、口金１と口金２の傾斜面側に設けた溝に設置したので、従来のクサビ原理を応用した機構の口金と比較すれば、本発明の口金は、コンパクトであり、本発明の口金をバイスの摺動面より離れた場所に取り付けられるので、バイス本体のスライド摺動面の掃除も楽になり、また、口金１の自動復帰用バネ９に依る、バイス本体のスライド摺動面の磨耗も無くなった。 Before the base 1 holds the workpiece, the spring 9 for sliding the base 1 is installed in a groove provided on the inclined surface side of the base 1 and the base 2 that has nothing to do with the sliding surface of the vise body. Therefore, compared with the base of the mechanism applying the conventional wedge principle, the base of the present invention is compact, and the base of the present invention can be attached at a location away from the sliding surface of the vice. Cleaning of the sliding surface of the slide is facilitated, and wear of the sliding surface of the vice body due to the automatic return spring 9 of the base 1 is eliminated.

実施の形態２は、分割した口金の分割面を密着させる手段と、摺動面の案内にアリ溝を使用したものであり、一個の摺動面の案内と口金１１の自動復帰用バネを二箇所設け、口金１１が安定して摺動する事を特徴する。
