Description
【０００１】[0001]
本考案はチャック装置の改善に係り、特に丸断面を有する長尺部材を従来より も小径のシリンダを用いて、しかも確実に挟持し得るようにしたチャック装置に 関するものある。 The present invention relates to an improvement of a chucking device, and more particularly to a chucking device in which a long member having a round cross section is securely clamped by using a cylinder having a diameter smaller than that of a conventional one.
【０００２】[0002]
周知のように、丸断面を有する長尺部材（以下、被挟持部材という）を挟持す るには通常チャック装置が用いられているが、このようなチャツク装置の一般例 には、例えばその断面構成説明図の図７，８に示すようなものが挙げられる。 先ず、図７に示すものはピニオンが一つのタイプで、ケーシング１に二つのシ リンダ２が水平かつ平行に内設され、これらシリンダ２に内設されてなるピスト ン３には相対する側に駆動ラック４ａが形成されると共に、相反する側の先端に ガイド部８を備えたピストンロッド４が貫通して嵌着されている。 As is well known, a chuck device is usually used to sandwich a long member having a circular cross section (hereinafter referred to as a sandwiched member). However, a typical example of such a chuck device is a cross section thereof. Examples are shown in FIGS. 7 and 8 of the configuration explanatory diagram. First, as shown in FIG. 7, the type of pinion is one, and two cylinders 2 are horizontally and parallelly installed in the casing 1, and the cylinders 2 installed in these cylinders 2 are on the opposite side. The drive rack 4a is formed, and the piston rod 4 provided with the guide portion 8 is fitted through at the opposite ends of the drive rack 4a.
【０００３】 同図において、上側のピストンロッド４の右側にはブッシュ５ａを介して下側 のピストンロッド４の右側のガイド部８が摺動自在に嵌合される挟持体支持部材 ５が固着される一方、下側のピストンロッド４の左側には、上側のピストンロッ ド４の左側のガイド部８がブッシュ５ａを介して嵌合される挟持体支持部材５が 固着される他、上・下側ピストンロッド４，４の駆動ラック４ａ，４ａの間には これらピストンロッド４，４の伸縮によって正逆回転されるピニオン６が介装さ れてなる構成になっている。従って、ピニオン６の正逆回転によって挟持体支持 部材５，５が離合するので、これらに固着される挟持体（図示省略）のチャック 部で被挟持部材が挟持される。In the figure, a holding member supporting member 5 to which a right guide portion 8 of the lower piston rod 4 is slidably fitted is fixed to the right side of the upper piston rod 4 via a bush 5a. On the other hand, on the left side of the lower piston rod 4, a sandwiching member supporting member 5 into which a left side guide portion 8 of the upper piston rod 4 is fitted via a bush 5a is fixed, and also on the upper and lower sides. Between the drive racks 4a and 4a of the piston rods 4 and 4, a pinion 6 which is rotated forward and backward by expansion and contraction of the piston rods 4 and 4 is interposed. Therefore, since the pinching member supporting members 5 and 5 are separated from each other by the forward and reverse rotations of the pinion 6, the held member is pinched by the chuck portion of the pinching member (not shown) fixed to these members.
【０００４】 次に、図８に示すものはピニオンが二つのタイプで、上記従来例と同一のもの 並びに同一機能を有するものを同一符号を以てこれを説明すると、ケーシング１ に一つのシリンダ２が垂直に設けられ、これに内設されてなるピストン３には相 対する側のそれぞれに駆動ラック４ａが形成されてなるピストンロッド４が突設 されると共に、これらの駆動ラック４ａに噛合う二つのピニオン６，６が設けら れている。そして、これらピニオン６，６にそれぞれ噛合する従動ラック７を有 する挟持体支持部材５，５が、水平な一本のガイドバー８を摺動して離合するよ うに構成されている。従って、ピストンロッド４の伸縮によってピニオン６が正 逆回転され、挟持体支持部材５，５が従動ラック７を介してガイドバー８を摺動 して離合するので、これらに固着される挟持体（図示省略）のチャック部によっ て被挟持部材が挟持される。Next, FIG. 8 shows two types of pinion, which are the same as those of the above-mentioned conventional example and those having the same function are described with the same reference numerals. One cylinder 2 is vertically attached to the casing 1. A piston rod 4 formed with a drive rack 4a formed on each of the opposite sides of the piston 3 provided in the inner side of the piston 3 and two pinions that mesh with these drive racks 4a. 6 and 6 are provided. Further, the sandwiching body supporting members 5 and 5 each having a driven rack 7 that meshes with the pinions 6 and 6 are configured to slide on and off a single horizontal guide bar 8. Therefore, the pinion 6 is rotated forward and backward by the expansion and contraction of the piston rod 4, and the holding member supporting members 5 and 5 slide on and off the guide bar 8 via the driven rack 7, so that the holding member fixed to them ( The member to be clamped is clamped by a chuck part (not shown).
【０００５】[0005]
ところで、上記従来技術の何れにあっても、挟持体を支持する挟持体支持部材 は、ピニオンよりも挟持体支持側がガイドバーにより案内される構成になってい る。被挟持部材を挟持しない状態においては挟持体支持部材は極めて滑らかにガ イドバーを摺動するが、被挟持部材を挟持して挟持体のチャック部に反力が作用 すると、挟持体支持部材の嵌合孔とガイドバーとの間に「こぜ」、つまりロック 現象が生じる。このようなロック現象のために、ピニオンに対して大トルクを付 与しなければならず、作動圧が一定の場合にはより大径のシリンダを採用しなけ ればならないという解決すべき課題があった。 By the way, in any of the above-mentioned conventional techniques, the sandwiching body supporting member for supporting the sandwiching body is configured such that the sandwiching body supporting side of the pinion is guided by the guide bar. The sandwiching body support member slides the guide bar extremely smoothly when the sandwiched member is not sandwiched, but when the sandwiched member is sandwiched and a reaction force acts on the chuck portion of the sandwiched body, the sandwiched body support member is fitted. A "knot" or locking phenomenon occurs between the dowel and the guide bar. Due to such a locking phenomenon, a large torque must be applied to the pinion, and when the working pressure is constant, a larger diameter cylinder must be adopted, which is a problem to be solved. there were.
【０００６】 さらに、被挟持部材の断面寸法がそれなりに高精度であれば、問題が少ないが 、例えば黒皮の丸鋼等を挟持しなければならない場合がある。その場合には挟持 力が強くとも４点支持のため水平な状態で挟持し得ない場合が生じるという解決 すべき課題もあった。[0006] Furthermore, if the sandwiched member has a relatively high cross-sectional dimension, there are few problems, but for example, black leather round steel or the like may have to be sandwiched. In that case, there was also a problem to be solved in that even if the clamping force was strong, it could not be clamped in a horizontal state because it was supported at four points.
【０００７】 従って、本考案の目的とするところは、従来に比較して小径のシリンダを用い て挟持体に対して大きな挟持力を付与して確実に被挟持部材を挟持することを可 能ならしめるチャック装置を提供するにある。Therefore, the object of the present invention is to use a cylinder having a smaller diameter than that of the prior art to apply a large holding force to the holding body and reliably hold the held member. A chuck device for tightening is provided.
【０００８】[0008]
【課題を解決するための手段】 本考案は、上記実情に鑑みてなされたものであって、従って本考案の請求項１ に係るチャック装置の構成の特徴とするところは、先端側の相対する側に最大の 開口寸法を有する三角溝状のチャック部を有する平行な一対の挟持体がガイドバ ーにより離合自在に支持され、該ガイドバーと前記挟持体のチャック部との間に ラックがこれら挟持体の相対する方向に平行に延設されると共に、これらラック の間にそれぞれのラックに噛み合う回転駆動自在なピニオンを介装したところに ある。Means for Solving the Problems The present invention has been made in view of the above circumstances, and therefore, the feature of the structure of the chuck device according to claim 1 of the present invention is that the tip end faces are opposed to each other. A pair of parallel nipping bodies having a triangular groove-shaped chuck portion with the maximum opening size on the side are supported by a guide bar so that they can be separated from each other, and a rack is held between the guide bar and the chuck portion of the nipping body. It is extended parallel to the opposite direction of the body, and a pinion rotatable between the racks and engaged with each rack is rotatably driven.
【０００９】 また、本考案の請求項２に係るチャック装置の構成の特徴とするところは、請 求項１記載のチャック装置において、前記一対の挟持体のうちの少なくとも何れ か一方のチャック部に、他方のチャック部側に最大の開口寸法を有する三角溝状 のチャック部を有する揺動チャック体を、その反チャック部側において水平軸心 回りに揺動可能に設けたところにある。Further, the feature of the configuration of the chuck device according to claim 2 of the present invention resides in that in the chuck device according to claim 1, at least one chuck part of the pair of holding bodies is provided. An oscillating chuck body having a triangular groove-shaped chuck portion having a maximum opening size on the other chuck portion side is provided so as to be swingable around a horizontal axis on the side opposite to the chuck portion.
【００１０】[0010]
従来例に係るチャック装置の作用を、その作用説明図の図５を参照しながら説 明すると、いまガイド部８とラック４ａとピニオン６の噛合部までの距離をＬ2 ，ラック４ａとピニオン６の噛合部から挟持体９のチャック部９ａまでの距離を Ｌ1 とし、ラック４ａを移動させるピニオン６の接線方向の力をＰとしたとき、 チャック部９ａが被挟持体１１に接触してＷの反力を受けたとする。The operation of the chuck device according to the conventional example will be described with reference to FIG. 5 which is an explanatory view of the operation. Now, the distance between the guide portion 8 and the meshing portion of the rack 4a and the pinion 6 is L 2 , and the rack 4a and the pinion 6 are. Let L 1 be the distance from the meshing part to the chuck portion 9a of the holding body 9 and P be the tangential force of the pinion 6 that moves the rack 4a. The chuck portion 9a contacts the held body 11 and W Suppose you have received the reaction force of
【００１１】 反力Ｗがガイドバー８を曲げようとする曲げモーメントＭW はＷＬ1 に、また 接線方向の力Ｐがガイド部８を曲げようとする曲げモーメントＭP はＰＬ2 とな る。一方、曲げモーメントＭW ，ＭP は挟持体支持部材５の厚さ方向の間隔をＢ （定数）とすれば、間隔Ｂの両端に作用する曲げモーメントによる反力Ｒにより 受持たれる。この曲げモーメントは２ＲＢであるが、２ＲＢ＝ＭW ＋ＭP ＝Ｗ・ Ｌ1 ＋Ｐ・Ｌ2 であるから、曲げモーメントによる反力Ｒ＝（ＷＬ1 ＋ＰＬ2 ） ／２Ｂとなり、接線方向の力Ｐが大きくなるとＲが大となる。そして、挟持体支 持部材５には接線方向の力Ｐに抗する２μＲの反力が作用する。The bending moment M W for the reaction force W to bend the guide bar 8 is WL 1 , and the bending moment M P for the tangential force P to bend the guide portion 8 is PL 2 . On the other hand, the bending moments M W and M P are received by the reaction force R due to the bending moments acting on both ends of the interval B, if the interval in the thickness direction of the sandwiching member support member 5 is B (constant). This bending moment is 2RB, 2RB = M W + M P = W · L 1 + because it is P · L 2, reaction force due to the bending moment R = (WL 1 + PL 2 ) / 2B , and the tangential force P Becomes larger, R becomes larger. Then, a reaction force of 2 μR against the tangential force P acts on the holding member support member 5.
【００１２】 これに対し、請求項１に係るチャック装置では、その作用説明図の図６に示す ように、挟持体９のチャック部９ａが被挟持部材１１に当接してＷの反力を受け ると、ＰＬ1 ＝ＷＬ1 の状態があり、従来例と同様のロック現象が生じるまでに は、挟持体支持部材５には移動し得る余地があるので、被挟持部材１１をより強 固に挟持することができる。On the other hand, in the chuck device according to the first aspect of the present invention, as shown in FIG. 6 of the operation explanatory view, the chuck portion 9a of the holding body 9 comes into contact with the held member 11 and receives the reaction force of W. Then, there is a state of PL 1 = WL 1 , and there is room for movement of the sandwiching member support member 5 until the same locking phenomenon as in the conventional example occurs, so that the sandwiched member 11 is more firmly fixed. Can be clamped.
【００１３】 また、請求項２に係るチャック装置によれば、請求項１に係るチャック装置の 作用に加えて、一対の挟持体のうちの少なくとも何れか一方のチャック部に、他 方のチャック部側に最大の開口寸法を有する三角溝状のチャック部を有する揺動 チャック体を、その反チャック部側において水平軸心回りに揺動可能に設けたの で、被挟持部材の形状に応じてチャック体が水平軸心回りに揺動して、被挟持部 材は三点支持される。According to the chuck device of the second aspect, in addition to the function of the chuck device of the first aspect, at least one of the pair of holding bodies has a chuck portion of the other chuck portion. The swing chuck body having a triangular groove-shaped chuck portion with the maximum opening size on the side is provided so as to swing around the horizontal axis on the side opposite to the chuck portion. The chuck body swings around the horizontal axis, and the sandwiched member is supported at three points.
【００１４】[0014]
以下、本考案に係る実施例を、その構成説明図の図１と、図１のＡ−Ａ線断面 図の図２と、図２のＢ矢視図の図３とを参照しながら、従来と同一のもの並びに 同一機能を有するものを同一符号を以て説明する。 Hereinafter, an embodiment according to the present invention will be described with reference to FIG. 1 showing the configuration thereof, FIG. 2 which is a sectional view taken along the line AA of FIG. 1, and FIG. 3 which is an arrow view of FIG. Those having the same function and having the same function will be described with the same reference numerals.
【００１５】 これらの図に示す符号１はケーシングであって、このケーシング１の内側には ２本のガイドバー８，８が平行かつ水平に設けられており、これらのガイドバー ８，８により、三角溝状のチャック部９ａを有する挟持体９が固着されてなる一 対の挟持体支持部材５が摺動自在に支持されている。挟持体９はチャック部９ａ の最大開口側が相対するように挟持体支持部材５の下部に固着されているが、こ れら挟持体９の一方のチャック部９ａには、三角溝状のチャック部１０ａの最大 開口側を他方の挟持体９のチャック部９ａ側に向けて、水平軸心回りに揺動自在 、かつ反チャック部１０ａ側の先鋭部がチャック部９ａの底に当接し得るように 揺動チャック体１０が設けられている。Reference numeral 1 shown in these drawings is a casing, and two guide bars 8 and 8 are provided in parallel and horizontally inside the casing 1. By these guide bars 8 and 8, A pair of sandwiching body support members 5 to which a sandwiching body 9 having a triangular groove-shaped chuck portion 9a is fixed is slidably supported. The holding body 9 is fixed to the lower part of the holding body support member 5 so that the maximum opening sides of the chuck portions 9a face each other. One chuck portion 9a of the holding body 9 has a triangular groove chuck portion. With the maximum opening side of 10a facing the chuck portion 9a side of the other holding body 9, it is possible to swing around the horizontal axis, and the sharpened portion on the side opposite to the chuck portion 10a can contact the bottom of the chuck portion 9a. A swing chuck body 10 is provided.
【００１６】 さらに、一対の挟持体支持部材５のそれぞれには相対する方向に、噛合歯４ｔ を相対する方向に向けた駆動ラック４ａが突設され、駆動ラック４ａ，４ａの間 には噛合歯４に噛合うピニオン６が介装されている。このピニオン６の回転中心 にはケーシング１により支持されてなる回転軸６ａが突設され、ケーシング１か ら突出する回転軸６ａの先端にはこの回転軸６ａと直行する方向にレバー６ｂが 突設されると共に、このレバー６ｂの遊端側には駆動シリンダ２のピストンロッ ド４の先端が枢着されてなる構成になっている。Further, a drive rack 4a is provided so as to project in a direction opposite to each of the pair of holding body support members 5 with the meshing teeth 4t facing each other, and the meshing teeth are provided between the drive racks 4a, 4a. A pinion 6 that meshes with 4 is interposed. A rotary shaft 6a supported by the casing 1 is provided at the center of rotation of the pinion 6, and a lever 6b is provided at the tip of the rotary shaft 6a protruding from the casing 1 in a direction orthogonal to the rotary shaft 6a. At the same time, the tip of the piston rod 4 of the drive cylinder 2 is pivotally attached to the free end side of the lever 6b.
【００１７】 従って、駆動シリンダ２のピストンロッド４の伸縮によって、レバー６ｂ，回 転軸６ａを介してピニオン６が正逆回転されるので、駆動ラック４ａ，挟持体支 持部材５を介して挟持体９が離合し、被挟持部材１１の挟持に際しては、被挟持 部材１１が挟持体９のチャック部９ａと、チャック体１０のチャック部１０ａに 当接するとチャック体１０が被挟持部材１１の外形状に応じて水平軸心回りに揺 動して、被挟持部材１１を三点支持により確実に挟持する。Therefore, as the piston rod 4 of the drive cylinder 2 expands and contracts, the pinion 6 rotates in the forward and reverse directions via the lever 6b and the rotation shaft 6a, so that the drive rack 4a and the sandwiching body supporting member 5 hold the pinion. When the bodies 9 are separated from each other and the sandwiched member 11 is sandwiched, when the sandwiched member 11 comes into contact with the chuck portion 9a of the sandwiched body 9 and the chuck portion 10a of the chuck body 10, the chuck body 10 moves outside the sandwiched member 11. It swings around the horizontal axis according to the shape, and securely holds the held member 11 by three-point support.
【００１８】 加えて、前記作用の項において説明したように、被挟持部材１１に挟持体９の チャック部９ａ，１０ａが当接しても、挟持体支持部材５，５がピニオン６の介 装位置よりも反チャック部９ａ，１０ａ側でガイドバー８によって案内される構 成のため、挟持体支持部材５，５がより接近して初めてロック現象を生じること になるので、挟持体９には充分な挟持力が付与され、被挟持部材１１は強い挟持 力で挟持されることとなる。In addition, as explained in the section of the action, even if the chucked portions 9a and 10a of the sandwiching body 9 come into contact with the sandwiched member 11, the sandwiching body supporting members 5 and 5 are located at the positions where the pinion 6 is interposed. Since the structure is guided by the guide bar 8 on the side opposite to the chuck portions 9a and 10a, the locking phenomenon occurs only when the holding body supporting members 5 and 5 come closer to each other. Therefore, the sandwiched member 11 is sandwiched with a strong sandwiching force.
【００１９】 勿論、ピニオン６に付与されるトルクはレバー６ｂの長さに係る。しかし、例 えレバー６の長さがピニオン６の半径に等しいとしても、従来よりも小径の駆動 シリンダ（等圧力）でも挟持体９に対して従来より大きな挟持力を付与し得るこ とを確認した。Of course, the torque applied to the pinion 6 depends on the length of the lever 6b. However, even if the length of the lever 6 is equal to the radius of the pinion 6, it has been confirmed that even a driving cylinder (equal pressure) having a smaller diameter than the conventional one can apply a greater clamping force to the clamping body 9 than the conventional one. did.
【００２０】 次に、チャック装置に係る他の実施例を、その模式的構成説明図の図４を参照 しながら、上記実施例と同一のもの並びに同等の機能を有するものを同一符号を 用いて以下に説明すると、この実施例は、周知の構成になる市販品であるトルク アクチュエータ２を用いてピニオンを回転させる構成としたものである。Next, referring to FIG. 4 of the schematic configuration diagram of another embodiment of the chuck device, the same components as those of the above embodiment and those having the same functions are designated by the same reference numerals. Explaining below, this embodiment has a structure in which a pinion is rotated by using a commercially available torque actuator 2 having a known structure.
【００２１】 詳しくは、トルクアクチュエータ２は、ピストン３の外周に螺旋溝３ａが周設 されており、この螺旋溝３ａにシリンダ筒の外部から挿入されてなるガイド部材 ２ａが嵌合しているために、ピストン３は回転しながら摺動する。そして、ピス トン３を貫通し、シリンダ筒から突出するピストンロッド４の先端にピニオン６ が固着されているが、ピストン３の摺動しながらの回転によってピストンロッド ４が回転される構成になるものである。Specifically, in the torque actuator 2, a spiral groove 3a is provided around the outer circumference of the piston 3, and a guide member 2a inserted from the outside of the cylinder is fitted into the spiral groove 3a. Moreover, the piston 3 slides while rotating. The pinion 6 is fixed to the tip of a piston rod 4 which penetrates the piston 3 and projects from the cylinder cylinder, but the piston rod 4 is rotated by the rotation of the piston 3 while sliding. Is.
【００２２】 この実施例の場合、例えば被挟持部材の挟持中において、トルクアクチュエー タ２に供給されている圧力媒体がシリンダ筒から抜けたとしても、ピニオン６の 自由回転が抑制されるため、挟持体９が自動的にロックされて開かなくなるので 、被挟持部材の挟持作業に際して極めて安全であるという効果がある。In the case of this embodiment, the free rotation of the pinion 6 is suppressed even if the pressure medium supplied to the torque actuator 2 escapes from the cylinder cylinder while the clamped member is being clamped. Since the holding body 9 is automatically locked and cannot be opened, there is an effect that the holding work is extremely safe in the holding work.
【００２３】 なお、以上では、何れか一方の挟持体９のチャック部９に揺動チャック体１０ を水平軸心回りに揺動自在に支持して、被挟持部材１１を三点支持する例を説明 したが、ロック現象を防ぐことにより小径の駆動シリンダでも挟持体９に対して 被挟持部材を挟持する充分な挟持力を付与し得るので、上記揺動チャック体１０ を設けなくてもそれなりに挟持能力を向上させることが可能である。In the above, an example in which the swing chuck body 10 is swingably supported around the horizontal axis on the chuck portion 9 of one of the sandwich bodies 9 and the sandwiched member 11 is supported at three points. As described above, since the locking phenomenon can be prevented, a sufficient holding force for holding the held member can be applied to the holding body 9 even with a small-diameter drive cylinder. It is possible to improve the gripping ability.
【００２４】[0024]
以上詳述したように、本考案の請求項１に係るチャック装置によれば、挟持体 を支持する挟持体支持部材がピニオンよりも挟持体の反チャック部側でガイドバ ーによってガイドされる構成のため、従来のように、挟持体のチャック部が被挟 持部材に当接してもロック現象が生じないので、より小径の駆動シリンダによっ て挟持体に充分な保持力が付与され、さらに請求項２に係るチャック装置によれ ば、一対の挟持体のうちの少なくとも何れか一方のチャック部に、他方のチャッ ク部側に最大の開口寸法を有する三角溝状のチャック部を有する揺動チャック体 を、その反チャック部側において水平軸心回りに揺動可能に設けたので、被挟持 部材の形状に応じて揺動チャック体が水平軸心回りに揺動して、被挟持部材は三 点支持されるので、小径の駆動シリンダによってもチャック装置の挟持能力を大 幅に向上させることができる。 As described above in detail, according to the chuck device of the first aspect of the present invention, the sandwiching body supporting member that supports the sandwiching body is guided by the guide bar on the side opposite to the chuck portion of the sandwiching body with respect to the pinion. Therefore, as in the conventional case, even if the chuck portion of the sandwiching body comes into contact with the sandwiched member, the locking phenomenon does not occur, so that a sufficient holding force is applied to the sandwiching body by the smaller diameter drive cylinder. According to the chuck device of Item 2, at least one chuck portion of the pair of holding bodies has a triangular groove-shaped chuck portion having a maximum opening size on the other chuck portion side, which is a swing chuck. Since the body is provided so as to be swingable around the horizontal axis on the side opposite to the chuck portion, the swing chuck body swings around the horizontal axis according to the shape of the sandwiched member, and the sandwiched member is moved in three directions. Supported by points , It is possible to improve the holding ability of the chuck device by a small-diameter drive cylinder to the large width.
