Description

この発明は、工作機械のテーブルに複数のワークを固定するのに用いるバイス装置及び当該バイス装置に使用するワーク受台に関するもので、特に複数のワークの把持及び開放を一操作で行うことができ、把持面が円弧状のワークの把持にも適した上記バイス装置及びワーク受台に関するものである。 The present invention relates to a vise device used for fixing a plurality of workpieces to a table of a machine tool and a work cradle used for the vise apparatus, and in particular, the plurality of workpieces can be gripped and released by one operation. The present invention relates to the vise device and the work cradle, which are also suitable for gripping a work having an arcuate gripping surface.

マシニングセンタなどの工作機械でワークを加工する場合、バイスを介してワークを工作機械のテーブルに固定することが一般的に行われている。比較的小型の多数のワークを加工するときは、バイスにワーク台や中間ジョーを取り付けて１個のバイスに多数のワークを把持できるようにすることで、加工能率と作業効率を向上させることができる。 When machining a work with a machine tool such as a machining center, it is common practice to fix the work to the table of the machine tool via a vise. When machining a large number of relatively small workpieces, it is possible to improve machining efficiency and work efficiency by attaching a work table or intermediate jaw to the vise so that a large number of workpieces can be gripped on one vise. can.

本願出願人は、例えば特許文献１、２などにより、１個のバイスで複数のワークを把持するのに用いるワーク支持台ないし受台を提案している。このようなワーク支持台や受台は、把持されるワークの形状に合わせて準備しなければならない場合も多い。 The applicant of the present application proposes a work support or a pedestal used for gripping a plurality of works with one vise, for example, in Patent Documents 1 and 2. In many cases, such a work support or pedestal must be prepared according to the shape of the work to be gripped.

ワークをバイスに把持して加工する場合、ワークの把持及び開放などの段取り作業を効率よく行うことができるようにする必要がある。この必要は、１個のバイスに複数のワークを把持して加工を行うときに特に重要である。バイスに把持された多数のワークの把持及び開放は、例えば流体圧を用いて一括して行う構造とすることもできるが、ワークが変わったときの流体配管の段取り替えが面倒になるなどの問題がある。 When the work is gripped by a vise for processing, it is necessary to be able to efficiently perform setup work such as gripping and opening the work. This need is particularly important when processing by gripping a plurality of workpieces on one vise. A large number of workpieces gripped by the vise can be gripped and released at once by using, for example, fluid pressure, but there is a problem that it becomes troublesome to set up the fluid pipe when the workpieces change. There is.

１個のバイスに複数のワークを把持して加工を行う場合、複数のワークの把持及び開放を簡単な操作で速やかに行うことができること、複数のワークが均一に把持及び開放されること、バイスに装着する支持台ないし受台が安価に製作できることなどが重要である。 When processing by gripping a plurality of workpieces on one vise, the plurality of workpieces can be gripped and released quickly with a simple operation, the plurality of workpieces can be uniformly gripped and released, and the vise. It is important that the support or pedestal to be mounted on the vehicle can be manufactured at low cost.

この発明は、１個のバイスに把持された複数のワークを通常行われるバイスの開閉動作で一括してかつ複数のワークのそれぞれについて均等に行うことができ、把持面が円弧状のワークも確実に把持することができ、かつ装置を安価に提供することが可能な、バイスのワーク受台及びバイス装置を得ることを課題としている。 According to the present invention, a plurality of works gripped by one vise can be collectively performed by opening and closing the vise, which is usually performed, and evenly for each of the plurality of works, and a work having an arcuate grip surface can be reliably performed. It is an object of the present invention to obtain a work cradle and a vise device of a vise that can be gripped and can be provided at a low cost.

この発明のワーク受台３は、工作機械のワークテーブルに装着してワークを固定するバイス１の対向する２つのジョー２(２a、２b、２c)、一般的には固定ジョー２ａと可動ジョー２ｂとの間のバイスの基台１１上に装着して２個以上のワークを支持するワーク受台である。 The work cradle 3 of the present invention has two opposing jaws 2 (2a, 2b, 2c) of a vise 1 mounted on a work table of a machine tool to fix a work, generally a fixed jaw 2a and a movable jaw 2b. It is a work cradle that is mounted on the base 11 of the vise between the two and supports two or more works.

この発明のワーク受台３は、バイスの基台１１に可動ジョー２ｂの進退方向（以下、「長手方向」と言う。）に移動自在に装着される台座３１と、台座３１の上面に長手方向に摺動可能に案内された座板３３と、この座板の上面に立設された仕切板３４と、台座３１を隣接するジョー２（２ａ、２ｂ、２ｃ）から離隔させる方向に押動する押棒４１とを備えている。加工しようとするワークＷは、仕切板３４の両側の座板３３上に載置される。 The work pedestal 3 of the present invention has a pedestal 31 that is movably mounted on the base 11 of the vise in the advancing / retreating direction of the movable jaw 2b (hereinafter, referred to as “longitudinal direction”) and a longitudinal direction on the upper surface of the pedestal 31. The seat plate 33 slidably guided to the seat plate 33, the partition plate 34 erected on the upper surface of the seat plate, and the pedestal 31 are pushed in a direction to be separated from the adjacent jaws 2 (2a, 2b, 2c). It is provided with a push rod 41. The work W to be processed is placed on the seat plates 33 on both sides of the partition plate 34.

座板３３及び押棒４１は、台座３１の端面側に押動されるようにバネ４２で付勢されている。バネ４２による座板３３の押動により、座板上の一方のワークＷｂの把持が開放され、押棒と座板の押動ストロークの差により、他方の隣接するジョー２側のワークＷａの把持が開放される。従って、バネ４２による座板３３の押動量は押棒４１の押動量より小さく、好ましくは１／２である。座板３３と押棒４１を押動するバネ４２は、個別に設けることも１個とすることもできる。 The seat plate 33 and the push rod 41 are urged by the spring 42 so as to be pushed toward the end surface side of the pedestal 31. The push of the seat plate 33 by the spring 42 releases the grip of one work Wb on the seat plate, and the difference in the push stroke between the push rod and the seat plate causes the grip of the work Wa on the other adjacent jaw 2 side to be gripped. Be released. Therefore, the pushing amount of the seat plate 33 by the spring 42 is smaller than the pushing amount of the push rod 41, preferably 1/2. The spring 42 that pushes the seat plate 33 and the push rod 41 may be provided individually or may be one.

１個のバネ４２で座板３３と押棒４１とを押動するときは、押棒４１が押動したあと当該押棒に係合して座板３３が押動するようにすれば良い。例えば、押棒４１の基端に大径部などの突部４６を形成し、バネ４２により押棒４１が押動したあと、突部４６が座板３３に係合して座板３３を押動するようにすれば良い。 When the seat plate 33 and the push rod 41 are pushed by one spring 42, the seat plate 33 may be pushed by engaging with the push rod after the push rod 41 is pushed. For example, a protrusion 46 having a large diameter or the like is formed at the base end of the push rod 41, and after the push rod 41 is pushed by the spring 42, the protrusion 46 engages with the seat plate 33 to push the seat plate 33. You can do it.

台座３１の長手方向の中央にワークＷｂに当接する仕切ジョー４を設けて、その両側に座板３３、押棒４１及びバネ４２を配置することにより、４個のワークＷを同時に把持及び開放するワーク受台３を得ることができる。 A partition jaw 4 that comes into contact with the work Wb is provided in the center of the pedestal 31 in the longitudinal direction, and a seat plate 33, a push rod 41, and a spring 42 are arranged on both sides of the partition jaw 4, so that the four work Ws are simultaneously gripped and released. The cradle 3 can be obtained.

この発明のバイス装置は、バイスの固定ジョー２ａと可動ジョー２ｂとの間の基台１１上に、隣接するワーク受台相互の間に長手方向に移動自在な中間ジョー２ｃを介して、この発明のワーク受台３の複数個を装着したバイス装置である。 The vise device of the present invention is the present invention via an intermediate jaw 2c that is movable in the longitudinal direction between adjacent work cradle on a base 11 between a fixed jaw 2a and a movable jaw 2b of the vise. This is a vise device equipped with a plurality of work cradle 3s.

この発明のバイス装置は、複数個のワークＷをバイス１の可動ジョー２ｂの進退動作により、一括して把持及び開放することができる。そして、ワーク開放時のワークＷとこれを把持するジョー２、４との間に形成される間隙を均一化することが可能であり、バイス装置へのワークＷの着脱を自動化することも容易である。更に、この発明のワーク受台３は、構造が簡単で製作が容易であるから、この発明のバイス装置を安価に構成できるという効果がある。 The vise device of the present invention can collectively grip and release a plurality of work Ws by moving the movable jaws 2b of the vise 1 forward and backward. Then, it is possible to make the gap formed between the work W at the time of opening the work and the jaws 2 and 4 that grip the work W uniform, and it is easy to automate the attachment / detachment of the work W to the vise device. be. Further, since the work cradle 3 of the present invention has a simple structure and is easy to manufacture, there is an effect that the vise device of the present invention can be constructed at low cost.

以下、実施例を示す図面を参照して、この発明を具体的に説明する。図において、１はバイス（図３参照）、１１はバイス１の基台、３は基台１１に装着されるワーク受台、３１はワーク受台３の台座、３２は台座３１の一部である仕切台、４はワークの寸法に応じて交換可能に仕切台３２に固定された仕切ジョー、３３は台座３１の上面に長手方向に摺動自在に装着された座板、３４は座板３３に固定された仕切板、４１は座板３３を長手方向に進退自在に貫通している押棒、４２は押棒４１の基部と仕切台３２との間に介装された圧縮バネである。 Hereinafter, the present invention will be specifically described with reference to the drawings showing examples. In the figure, 1 is a vise (see FIG. 3), 11 is a base of the vise 1, 3 is a work pedestal mounted on the base 11, 31 is a pedestal of the work pedestal 3, and 32 is a part of the pedestal 31. A partition table 4 is a partition jaw fixed to the partition table 32 so as to be replaceable according to the dimensions of the work, 33 is a seat plate slidably mounted on the upper surface of the pedestal 31 in the longitudinal direction, and 34 is a seat plate 33. 41 is a push rod fixed to the seat plate 33 so as to be able to advance and retreat in the longitudinal direction, and 42 is a compression spring interposed between the base of the push rod 41 and the partition base 32.

図に示すワーク受台３は、仕切ジョー４の長手両側に座板３３、押棒４１及びバネ４２を対称に配置することにより、４個のワークＷ（Ｗａ、Ｗｂ）を同時に把持及び開放することができるようにしたもので、その片側のみの構造で、２個のワークＷを同時に把持及び開放可能なワーク受台とすることができるものである。 In the work cradle 3 shown in the figure, four work Ws (Wa, Wb) are simultaneously gripped and released by arranging the seat plate 33, the push rod 41, and the spring 42 symmetrically on both long sides of the partition jaw 4. With a structure of only one side thereof, it is possible to use two work Ws as a work cradle that can be gripped and opened at the same time.

台座３１は、バイスの基台１１に摺動自在に嵌合するガイド部を備え、上縁両側に座板３３を摺動自在に案内するガイドレール３５を備えている。台座３１の上面中央には、幅方向（長手直角方向）の切り欠き３６が設けられて、仕切台３２をこの切り欠き３６内にキー３７で位置決めして固定し、この仕切台３２にワークＷｂの寸法に応じて交換できるようにして、仕切ジョー４が固定されている。台座３１の一部となる仕切台３２を分割構造で設けたのは、長手方向のガイドレール３５の機械加工を可能にするためである。 The pedestal 31 is provided with a guide portion that is slidably fitted to the base 11 of the vise, and is provided with guide rails 35 that slidably guide the seat plate 33 on both sides of the upper edge. A notch 36 in the width direction (longitudinal right angle direction) is provided in the center of the upper surface of the pedestal 31, and the partition table 32 is positioned and fixed in the notch 36 by a key 37, and the work Wb is fixed to the partition table 32. The partition jaw 4 is fixed so that it can be replaced according to the dimensions of. The partition base 32, which is a part of the pedestal 31, is provided in a divided structure in order to enable machining of the guide rail 35 in the longitudinal direction.

座板３３は、ワークＷの受座となる部材で、台座３１のガイドレール３５に摺動自在に装着されている。座板３３の上面に設けた仕切板３４は、２個のワーク、特に把持面が円弧状のワークＷを安定に把持可能にするために設けられたものである。 The seat plate 33 is a member that serves as a seat for the work W, and is slidably mounted on the guide rail 35 of the pedestal 31. The partition plate 34 provided on the upper surface of the seat plate 33 is provided to enable stable gripping of two workpieces, particularly a workpiece W having an arcuate gripping surface.

台座３１及び座板３３は、座板３３上に長手方向の寸法が最小のワーク（図５の寸法Ｂが最小のワーク）を載置したときにもそのワークの端縁Ｅが台座３１及び座板３３から突出する長さにしなければならない。換言すれば、バイス１で座板３３上のワークＷを把持したとき、ジョー２が台座３１や座板３３に当接する前にワークＷに当接する長さにしなければならない。 The pedestal 31 and the seat plate 33 have the pedestal 31 and the seat at the edge E of the work even when the work having the smallest length dimension (the work having the smallest dimension B in FIG. 5) is placed on the seat plate 33. It must be long enough to protrude from the plate 33. In other words, when the work W on the seat plate 33 is gripped by the vise 1, the length must be set so that the jaw 2 abuts on the work W before abuting on the pedestal 31 or the seat plate 33.

座板３３には、仕切ジョー４側を大径のバネ収納部４３にした長手方向の貫通孔４４が設けられており、この貫通孔に押棒４１がその大径の突部４６をバネ収納部４３に収納した状態で摺動自在に挿通されている。バネ収納部４３には、押棒の基端と台座３１の一部となっている仕切台３２との間に両者を離隔方向に付勢する圧縮バネ４２が収納されている。 The seat plate 33 is provided with a through hole 44 in the longitudinal direction in which the partition jaw 4 side is a large-diameter spring accommodating portion 43, and the push rod 41 inserts the large-diameter protrusion 46 into the spring accommodating portion in this through hole. It is slidably inserted in the state of being stored in 43. The spring accommodating portion 43 accommodates a compression spring 42 that urges the base end of the push rod and the partition base 32, which is a part of the pedestal 31, in the separation direction.

圧縮バネ４２は、伸張したとき、押棒４１をその先端４７が座板３３上のワークＷａの端縁Ｅを若干超える位置まで押動し、その押動途中で押棒の突部４６がバネ収納部４３の底面となっている係合面４５に当接して、座板３３を押し動かす。座板３３の押動量により、仕切ジョー４側のワークＷｂの開量が設定され、押棒の先端４７がワークＷａの端縁Ｅを超える程度によって固定ジョー２ａ及び中間ジョー２ｃ側のワークＷａの開放量が設定される。ここで言う開放量は、ワークＷを座板３３上から着脱するのに要する隙間寸法に対応する寸法である。 When the compression spring 42 is extended, the push rod 41 is pushed to a position where the tip 47 thereof slightly exceeds the edge E of the work Wa on the seat plate 33, and the protrusion 46 of the push rod is in the spring accommodating portion during the push. The seat plate 33 is pushed and moved in contact with the engaging surface 45 which is the bottom surface of the 43. The opening amount of the work Wb on the partition jaw 4 side is set by the pushing amount of the seat plate 33, and the opening of the fixed jaw 2a and the work Wa on the intermediate jaw 2c side is set by the extent that the tip 47 of the push rod exceeds the edge E of the work Wa. The amount is set. The opening amount referred to here is a dimension corresponding to the clearance dimension required for attaching and detaching the work W from the seat plate 33.

上記構造のワーク受台３は、図３に示すように、バイス１の固定ジョー２ａと可動ジョー２ｂとの間の基台１１上に装着される。複数のワーク受台３を装着するときは、相互の間に中間ジョー２ｃを装着する。中間ジョー２ｃ及び中間ジョー２ｃより可動ジョー２ｂ側のワーク受台３は、長手方向すなわちワークＷの把持及び開放方向に移動可能にして基台１１に装着する必要がある。 As shown in FIG. 3, the work cradle 3 having the above structure is mounted on the base 11 between the fixed jaw 2a and the movable jaw 2b of the vise 1. When a plurality of work cradle 3s are mounted, intermediate jaws 2c are mounted between them. The work cradle 3 on the movable jaw 2b side of the intermediate jaw 2c and the intermediate jaw 2c needs to be movable in the longitudinal direction, that is, in the gripping and opening direction of the work W, and mounted on the base 11.

図３のバイス１は、工作機械のワークテーブルに固定される細長い角柱状の基台１１と、基台１１の一端に固定された固定ジョー２ａと、固定ジョー２ａに対向して進退する可動ジョー２ｂと移動台１２とを備えている。基台１１は、その両側面にガイド溝１３が設けられている。移動台１２、可動ジョー２ｂ、ワーク受台３及び中間ジョー２ｃは、基台１１と摺動自在に嵌合するガイド部を備えている。 The vise 1 of FIG. 3 has an elongated prismatic base 11 fixed to a work table of a machine tool, a fixed jaw 2a fixed to one end of the base 11, and a movable jaw that moves forward and backward facing the fixed jaw 2a. It is provided with 2b and a moving table 12. The base 11 is provided with guide grooves 13 on both side surfaces thereof. The moving table 12, the movable jaw 2b, the work cradle 3, and the intermediate jaw 2c are provided with a guide portion that is slidably fitted to the base 11.

移動台１２は、基台１１の側面に設けた複数の基台側ピン穴１４・・・の一つと移動台１２に設けた移動台側ピン穴１５とを一致させた円穴にピンを挿入することにより、所望の位置で基台１１に固定可能である。可動ジョー２ｂは、移動台１２に軸方向移動不能かつ回動可能に設けられたネジ杆１６と螺合しており、ネジ杆１６を回動することにより、移動台１２に対して相対的に進退してワークＷ（Ｗａ、Ｗｂ）の把持及び開放を行う。この進退ストロークを基台側ピン穴１４の配置ピッチより大きくすることで、固定ジョーと可動ジョーの間隔を連続的に変えることができる。 The moving table 12 inserts a pin into a circular hole in which one of a plurality of base-side pin holes 14 ... Provided on the side surface of the base 11 and the moving table-side pin hole 15 provided on the moving table 12 are matched. By doing so, it can be fixed to the base 11 at a desired position. The movable jaw 2b is screwed with a screw rod 16 provided on the moving table 12 so as not to be movable in the axial direction and is rotatable. By rotating the screw rod 16, the movable jaw 2b is relatively relative to the moving table 12. The work W (Wa, Wb) is gripped and released by advancing and retreating. By making this advancing / retreating stroke larger than the arrangement pitch of the base side pin hole 14, the distance between the fixed jaw and the movable jaw can be continuously changed.

図３のバイス装置において、２個のワーク受台３の仕切板３４とジョー２（２ａ、２ｂ、２ｃ）及び仕切ジョー４の間にワークＷを挿入して、可動ジョー２ｂをワーク把持方向に進出させると、まず押棒４１の先端４７が可動ジョー２ｂ、中間ジョー２ｃ及び固定ジョー２ａに当接してバネ４２を圧縮し、これらのジョー２側のワークＷａの端縁Ｅに当接する。そして更に可動ジョー２ｂが進出すると、可動ジョー２ｂ、中間ジョー２ｃ及び固定ジョー２ａ側のワークＷａを介して仕切板３４、従って座板３３が押され、仕切ジョー４側のワークＷｂが仕切ジョー４に当接し、この状態で可動ジョー２ｂに所望の把持力を加えることにより、２個のワーク受台上のすべてのワークが固定される。 In the vise device of FIG. 3, the work W is inserted between the partition plate 34 of the two work cradle 3 and the jaws 2 (2a, 2b, 2c) and the partition jaw 4, and the movable jaw 2b is moved in the work gripping direction. When advanced, the tip 47 of the push rod 41 first abuts on the movable jaw 2b, the intermediate jaw 2c, and the fixed jaw 2a to compress the spring 42, and abuts on the edge E of the work Wa on the jaw 2 side. When the movable jaw 2b further advances, the partition plate 34, and therefore the seat plate 33, is pushed via the movable jaw 2b, the intermediate jaw 2c, and the work Wa on the fixed jaw 2a side, and the work Wb on the partition jaw 4 side becomes the partition jaw 4. By applying a desired gripping force to the movable jaw 2b in this state, all the workpieces on the two workpiece cradle are fixed.

ワークを加工した後、可動ジョー２ｂを開くと、バネ４２の付勢力で押棒４１が進出して可動ジョー２ｂ、中間ジョー２ｃ及び固定ジョー２ａ側のワークＷａを開放し、次いで押棒４１の突部４６がバネ収納部４３の底面となっている係合面４５に当接して座板３３が押し動かされ、仕切ジョー４側のワークＷｂが開放され、ワークＷの把持面とジョー２、４との間にワークの着脱に必要な間隙が形成される。 When the movable jaw 2b is opened after processing the work, the push rod 41 advances by the urging force of the spring 42 to open the movable jaw 2b, the intermediate jaw 2c, and the work Wa on the fixed jaw 2a side, and then the protrusion of the push rod 41. The seat plate 33 is pushed and moved when the 46 comes into contact with the engaging surface 45 which is the bottom surface of the spring accommodating portion 43, the work Wb on the partition jaw 4 side is opened, and the gripping surface of the work W and the jaws 2 and 4 A gap necessary for attaching and detaching the work is formed between the two.

把持方向の寸法（図５の寸法Ｂ）が異なるワークを把持するときは、仕切ジョー４の交換ないし仕切ジョー４に例えば図４に示すようなスペーサ４８を嵌着することにより、ワークの着脱に必要な上記間隙を一定にできる。すなわち、ワークを把持したときの仕切ジョー４の中心から仕切板３４迄の距離が一定になるような寸法の仕切ジョー４とすれば良い。 When gripping workpieces having different dimensions in the gripping direction (dimension B in FIG. 5), the work can be attached / detached by replacing the partition jaw 4 or by fitting a spacer 48 as shown in FIG. 4 to the partition jaw 4. The required gap can be made constant. That is, the partition jaw 4 may have dimensions such that the distance from the center of the partition jaw 4 to the partition plate 34 when the work is gripped is constant.

この発明のワーク受台及びバイス装置は、多数のワークを一操作で同時に把持及び開放でき、構造も簡単で比較的安価に提供できる。そして、ワークの把持を開放したときのワークと仕切板やジョーなどとの間の間隙を比較的正確に設定できるので、ワークの着脱を自動化する場合にも確実な着脱動作が可能になる。また、図５に示しだ端縁が円弧状のワークでも安定に把持して固定することができる。 The work cradle and vise device of the present invention can grip and open a large number of works at the same time with one operation, have a simple structure, and can be provided at a relatively low cost. Further, since the gap between the work and the partition plate, the jaw, or the like when the grip of the work is released can be set relatively accurately, it is possible to perform a reliable attachment / detachment operation even when the attachment / detachment of the work is automated. Further, even a work having an arcuate edge as shown in FIG. 5 can be stably gripped and fixed.

実施例に示したワーク受台３は、仕切ジョー４の両側に２個ずつの４個のワークを把持できるようにしたものであるが、例えば仕切ジョー４の中心で分割した構造にすれば、２個のワークの把持に使用するワーク受台とすることができる。また、図の実施例では１個のバネで押棒と座板を進退させるようにしているが、それぞれを別個のバネで進退させるようにすることも可能である。 The work cradle 3 shown in the embodiment is designed so that four works, two each on both sides of the partition jaw 4, can be gripped. For example, if the structure is divided at the center of the partition jaw 4, It can be a work cradle used for gripping two works. Further, in the embodiment shown in the figure, the push rod and the seat plate are advanced and retracted by one spring, but it is also possible to advance and retreat each by a separate spring.
