Description

この発明は、板状のワークの側辺部を面方向に移動可能かつ面直角方向に移動不能に保持する側辺部ホルダを備えた硬質脆性板の側辺加工装置に関するものである。 The present invention relates to the side machining apparatus hard and brittle plate having a side portion Hol da for immovably holding the side portion of the plate-shaped workpiece on a movable and a surface perpendicular to the plane direction.

板状のワークの側辺の加工、例えば回転砥石でガラス板の側辺の面取加工を行うときは、ワークテーブルから加工しようとする側辺を張り出させた状態でワークを保持する必要がある。このワークの張出し量が過大であると、自重でワークが撓んだり、工具から受ける加工反力でワークが振動したりするので、ワークの張出し量を工具とワークテーブルとの干渉を避けるのに必要な最小限の寸法にするのが好ましい。   When processing the side of a plate-shaped workpiece, for example, when chamfering the side of a glass plate with a rotating grindstone, it is necessary to hold the workpiece with the side to be processed protruding from the work table. is there. If the amount of overhang of the workpiece is excessive, the workpiece will be bent by its own weight or the workpiece will vibrate due to the processing reaction force received from the tool. It is preferred to have the minimum required dimensions.

一方、ワークには種々の寸法のものがあり、縦横比も様々である。そして、ワーク寸法に合わないワークテーブルを用いると、テーブルからのワーク張出し量が少なすぎて、工具とテーブルの干渉により加工が不能になったり、張出し量が過大となって上述のような不都合が生ずるので、ワーク寸法や縦横比が変わる毎に、そのワークに適合した寸法のテーブルを製作して、テーブルの交換作業を行わなければならない。   On the other hand, there are workpieces of various sizes and various aspect ratios. If a work table that does not match the workpiece dimensions is used, the amount of work overhang from the table is too small, making it impossible to process due to the interference between the tool and the table, and the overhang is excessive, resulting in the inconveniences described above. Therefore, every time the workpiece dimensions and aspect ratio change, a table having dimensions suitable for the workpiece must be manufactured and the table must be exchanged.

しかし、ワークの寸法や縦横比に応じてそれぞれに適合するテーブルを製作するのは、コストがかかり、テーブル交換を自動的に行おうとすると、複雑な構造の自動交換装置を必要とし、またテーブル交換を人手で行うときは、煩雑で段取りに時間がかかるという問題が生ずる。   However, it is costly to produce a table that suits the dimensions and aspect ratio of the workpiece, and if an attempt is made to change the table automatically, an automatic changer with a complicated structure is required. When performing the above process manually, there arises a problem that it is complicated and takes time to set up.

この問題を解決するべく本願出願人は、特許文献１でテーブル寸法を自在に変えることができる硬質脆性板の側辺加工装置を提案している。
特開２００４−７４３０３号公報 In order to solve this problem, the applicant of the present application has proposed a side processing apparatus for a hard and brittle plate that can freely change the table dimensions in Patent Document 1.
JP 2004-74303 A

しかし、上記特許文献１で提案した装置は、テーブル構造が複雑になるため、装置コストを上昇させ、またワークの縦横比の変化には対応できないという問題があり、十分な解決手段とはなっていなかった。   However, the apparatus proposed in Patent Document 1 has a problem in that the table structure is complicated, which increases the apparatus cost and cannot cope with the change in the aspect ratio of the workpiece, and is not a sufficient solution. There wasn't.

そこでこの発明は、より構造が簡単で、寸法や縦横比の異なるワークの総てに対応することが可能な新たな技術手段を得ることを課題としている。   Accordingly, an object of the present invention is to obtain new technical means that is simpler in structure and can cope with all workpieces having different dimensions and aspect ratios.

この発明は、加工装置のテーブル２に保持されたワークの側辺部１ａを、その加工辺１ｂを加工する工具３の近傍で、ワーク１の面方向に移動自在かつ面直角方向に移動不能に保持する側辺部ホルダ４を、工具３を支持している工具側フレーム１０に装着して設けることにより、上記課題を解決したものである。   In the present invention, the side 1a of the workpiece held on the table 2 of the machining apparatus is movable in the surface direction of the workpiece 1 and not movable in the direction perpendicular to the surface in the vicinity of the tool 3 for machining the machining side 1b. The above-mentioned problem is solved by mounting the side holder 4 to be held on the tool side frame 10 that supports the tool 3.

すなわち、本願請求項１の発明に係る硬質脆性板の側辺加工装置は、加工するワーク１の側辺部１ａをその表裏面に向けて流出する流体圧で表裏方向に挟持する側辺部ホルダ４を備えている。   That is, the side processing apparatus of the hard brittle plate according to the invention of claim 1 is a side holder that holds the side 1a of the workpiece 1 to be processed in the front and back direction with the fluid pressure flowing out toward the front and back. 4 is provided.

ワーク１の側辺加工は、テーブル２と工具３とを加工する加工辺１ｂ方向に相対移動させることによって行われる。この発明の側辺部ホルダ４は、テーブル２に対して相対移動し、工具３に対しては相対移動しない。   Side processing of the workpiece 1 is performed by relatively moving the table 2 and the tool 3 in the processing side 1b direction. The side holder 4 of the present invention moves relative to the table 2 and does not move relative to the tool 3.

請求項２の発明に係る上記側辺加工装置の側辺部ホルダは、硬質脆性板の側辺加工工具３に近接してそのワーク１側に配置され、当該工具で加工されるワークの側辺部表裏面に遊隙を介して対峙する一対の案内面６ａ、６ｂの間隔を調整する調整装置と、少なくとも下方の案内面６ｂを退避させる退避装置１１とを備えているというものである。 Side portion holder of the sides machining apparatus according to a second aspect of the invention, the side of the workpiece proximate to the side edge machining tool 3 of hard and brittle plate is disposed on the workpiece 1 side, it is processed in this the tool It is provided with an adjusting device for adjusting the distance between the pair of guide surfaces 6a and 6b facing each other on the front and back sides of the side portion and a retracting device 11 for retracting at least the lower guide surface 6b .

側辺部ホルダ４は、ワーク１の表裏面（通常は上下面）に遊隙をもって対峙する一対の案内面６ａ、６ｂを備え、上記遊隙に形成される流体層を介してワーク側辺部１ａを挟持する。この案内面は、多孔質材料で形成するか、または孔あき板で形成されて、前記流体層は当該多孔質材料ないし孔あき板の孔から流出する流体によって形成される。 The side part holder 4 includes a pair of guide surfaces 6a and 6b facing each other with a gap on the front and back surfaces (usually upper and lower surfaces) of the work 1, and the work side part via a fluid layer formed in the gap. Hold 1a. The guide surface is formed of a porous material or a perforated plate, and the fluid layer is formed of a fluid flowing out of the porous material or a hole of the perforated plate.

上下の案内面６ａ、６ｂは、ワーク１の表裏面に近接して位置する。前記流体層が薄ければ薄いほど、ワークの側辺部１ａは、上下の案内面６ａ、６ｂによってより高い剛性で保持される。上下の案内面６ａ、６ｂの間隔をワーク１の厚さに応じて調整可能にすることにより、厚さの異なるワークに対する強力な保持が可能になる。また、ワーク１をテーブル２に着脱する際、あるいはテーブル２を回転してワーク１の加工辺を変更するときに、案内面６ａ、６ｂとワーク１とが衝突するのを避けるために、案内面６ａ、６ｂ、特に案内面を上下に配置したときの下方の案内面６ｂの退避装置を設けることが一般的に要求される。   The upper and lower guide surfaces 6 a and 6 b are located close to the front and back surfaces of the workpiece 1. The thinner the fluid layer, the more rigid the side 1a of the workpiece is held by the upper and lower guide surfaces 6a, 6b. By making it possible to adjust the distance between the upper and lower guide surfaces 6a and 6b according to the thickness of the workpiece 1, it is possible to strongly hold workpieces having different thicknesses. In order to avoid the collision between the guide surfaces 6a and 6b and the workpiece 1 when the workpiece 1 is attached to or detached from the table 2 or when the processing side of the workpiece 1 is changed by rotating the table 2, the guide surface is avoided. It is generally required to provide a retracting device for the lower guide surface 6b when the guide surfaces 6a and 6b are arranged vertically.

ワークの加工部を工具３に対して正確な位置で保持するためには、上下の案内面６ａ、６ｂの特にワークの相対移動方向の寸法を大きくするのが好ましい。なお、保持剛性を高くできることから、流体としては気体より液体を使用するのが有利であると考えられる。   In order to hold the workpiece processing portion at an accurate position with respect to the tool 3, it is preferable to increase the size of the upper and lower guide surfaces 6a and 6b, particularly in the relative movement direction of the workpiece. Since the holding rigidity can be increased, it is considered advantageous to use a liquid rather than a gas as the fluid.

この発明の側辺加工装置では、テーブル２から張出したワークの側辺部１ａを側辺部ホルダ４によって保持した状態で加工を行う。テーブル２は工具３に対して加工する加工辺１ｂの方向に相対移動するが、側辺部ホルダ４は常時工具３の近傍において、ワークの側辺部１ａを面直角方向に移動不能に挟持しており、従ってワーク１の現に加工される加工辺１ｂは、重力によって垂れ下がったり、加工反力によって振動したりすることなく、工具３に対する正確な相対位置関係が保証される。 The sides machining apparatus of the present invention, for machining a side edge portion 1a of the workpiece out of the table 2 Zhang while holding the side portions holder 4. The table 2 moves relative to the tool 3 in the direction of the machining side 1b. However, the side holder 4 always holds the side 1a of the workpiece so as not to move in the direction perpendicular to the surface in the vicinity of the tool 3. Therefore, the machining edge 1b that is actually machined of the workpiece 1 is guaranteed to have an accurate relative positional relationship with respect to the tool 3 without drooping due to gravity or vibrating due to machining reaction force.

側辺部ホルダ４は、工具３を支持している工具側フレーム１０に装着すれば、ワーク寸法や縦横比が変わっても、ワークの現に加工される部分が工具３との相対位置変動を生ずることなく保持される。すなわち、ワーク寸法が大きくなって工具側フレーム１０をテーブル２から離隔させたときには、側辺部ホルダ４もテーブル１から離隔して、現に加工される加工辺１ｂの直近でワーク１を保持する。また、ワークの側辺長さが長大であっても、テーブル２の相対移動に伴ってワーク側辺部１ａは上下の案内面６ａ、６ｂの間を通過して行き、現に加工される加工辺１ｂ近傍が常に側辺部ホルダ４で保持される。   If the side holder 4 is attached to the tool-side frame 10 that supports the tool 3, even if the workpiece dimensions and aspect ratio change, the part that is actually processed of the workpiece will change relative to the tool 3. Retained without. That is, when the workpiece size is increased and the tool side frame 10 is separated from the table 2, the side holder 4 is also separated from the table 1, and the workpiece 1 is held in the immediate vicinity of the machining side 1b to be processed. Even if the side length of the workpiece is long, the workpiece side portion 1a passes between the upper and lower guide surfaces 6a and 6b with the relative movement of the table 2 and is actually processed. The vicinity of 1b is always held by the side holder 4.

すなわち、この発明の側辺加工装置では、ワークの寸法や縦横比が変わったときに、テーブル２を頻繁に交換する必要がない。テーブルの交換が必要になるのは、ワーク１の側辺の張出し量が大きくなってワークの自重によってワークが割れるなどの事故が発生するおそれがあるときである。   That is, in the side processing apparatus of the present invention, it is not necessary to frequently change the table 2 when the dimensions and aspect ratio of the workpiece change. The table needs to be replaced when there is a possibility that an accident such as the work being cracked due to the weight of the work due to a large amount of extension of the side of the work 1 occurs.

以下、図面を参照して、この発明の実施形態を説明する。図１は、この発明の側辺加工装置で、矩形板状のワーク１の対向側辺を同時加工している状態を示す模式的な斜視図で、２はワーク１を真空吸着等により固定しているテーブル、３は側辺加工用の砥石ユニット、４は側辺部ホルダである。 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic perspective view showing a state in which the opposite sides of a rectangular plate-like workpiece 1 are being simultaneously machined by the side processing apparatus of the present invention. Reference numeral 2 denotes a workpiece 1 fixed by vacuum suction or the like. and it has a table, 3 grindstone unit for sides machining 4 is a side portion holder.

テーブル２はワーク１の中央部下面を支持しており、ワークの側辺部１ａは、テーブル２の外側に張出している。図に示した砥石ユニット３は、ワークの加工辺１ｂと平行な軸回りに回転する上下の回転砥石３ａ、３ｂを備えた面取加工用の砥石で、上下の砥石の回転方向は、図３に矢印Ａで示されている。   The table 2 supports the lower surface of the central portion of the workpiece 1, and the side portion 1 a of the workpiece projects outside the table 2. The grindstone unit 3 shown in the figure is a chamfering grindstone provided with upper and lower rotating grindstones 3a and 3b that rotate around an axis parallel to the machining side 1b of the workpiece. The rotation direction of the upper and lower grindstones is as shown in FIG. Is indicated by an arrow A.

側辺部ホルダ４は、砥石ユニット３の直近で、ワークの側辺部１ａを上下方向に挟持する２枚の案内面６ａ、６ｂを備えており、上下の案内板の対向面がワークの側辺部１ａを案内する案内面６ａ、６ｂとなっている。図２は、下方の案内板５ｂの斜視図で、その案内面６ｂには、多数の流出孔７が分布しており、これらの流出孔に圧力流体（一般的には水）を供給するパイプ８が接続されている。   The side holder 4 is provided with two guide surfaces 6a and 6b which are close to the grindstone unit 3 and sandwich the side 1a of the workpiece in the vertical direction, and the opposing surfaces of the upper and lower guide plates are on the workpiece side. The guide surfaces 6a and 6b guide the side portion 1a. FIG. 2 is a perspective view of the lower guide plate 5b. A large number of outflow holes 7 are distributed on the guide surface 6b, and a pipe for supplying pressure fluid (generally water) to these outflow holes. 8 is connected.

案内板５の前縁（砥石ユニット側の辺）５ｃの中央部には当該案内板を退避させたときの砥石３との干渉を避けるための切欠９が設けられている。図２にこの切欠が３個示されているのは、図の砥石ユニット３が上下それぞれ３枚の砥石車を備えているからである。上側の案内板５ａは、下側の案内板５ｂの上下を逆にした構造であるが、切欠９はその配設間隔の２分の１だけずれている。これは上下の砥石車が互いに相手側の砥石車の間に入り込むように軸方向にずらして設けられているからである。   A notch 9 for avoiding interference with the grindstone 3 when the guide plate is retracted is provided at the center of the front edge (side on the grindstone unit) 5c of the guide plate 5. The reason why three notches are shown in FIG. 2 is that the grindstone unit 3 shown in the drawing includes three grindstone wheels on the upper and lower sides. The upper guide plate 5a has a structure in which the lower guide plate 5b is turned upside down, but the notch 9 is shifted by a half of the arrangement interval. This is because the upper and lower grinding wheels are offset in the axial direction so as to enter each other's grinding wheel.

砥石ユニット３は、上下の砥石３ａ、３ｂの外周がワークの側辺部１ａの上下のエッジに接するように位置設定されている。側辺部ホルダ４は、その前縁５ｃを上下の砥石３ａ、３ｂの外周に接近させ、かつ上下の案内面６ａ、６ｂの間隔をワーク１の板厚より僅かに広い間隔となるように位置設定されている。砥石ユニット３及び側辺部ホルダ４の高さは、それらの上下の砥石３ａ、３ｂ及び上下の案内面６ａ、６ｂの高さ中間位置がテーブル２上におけるワーク１の板厚中心と一致する高さである。   The grindstone unit 3 is positioned so that the outer circumferences of the upper and lower grindstones 3a and 3b are in contact with the upper and lower edges of the side portion 1a of the workpiece. The side holder 4 is positioned so that the front edge 5c approaches the outer periphery of the upper and lower grindstones 3a and 3b, and the distance between the upper and lower guide surfaces 6a and 6b is slightly wider than the plate thickness of the workpiece 1. Is set. The height of the grindstone unit 3 and the side holder 4 is such that the middle position between the upper and lower grindstones 3a and 3b and the upper and lower guide surfaces 6a and 6b coincides with the plate thickness center of the workpiece 1 on the table 2. That's it.

砥石ユニット３によるワーク１の側辺加工は、テーブル２を砥石ユニット３に対して加工する加工辺１ｂの方向に相対移動させることによって行われる。このとき、砥石ユニット３と側辺部ホルダ４の相対位置関係は変化しない。側辺部ホルダの案内面６ａ、６ｂとワーク１の表裏面との間には、これらの案内面の流出孔７から流出する流体によって流体膜が形成されており、テーブル２の移動に伴ってワークの側辺部１ａは、この流体膜に挟持された状態で上下の案内面６ａ、６ｂの間を通過して行く。   The side processing of the workpiece 1 by the grindstone unit 3 is performed by relatively moving the table 2 in the direction of the processing side 1b to be processed with respect to the grindstone unit 3. At this time, the relative positional relationship between the grindstone unit 3 and the side holder 4 does not change. A fluid film is formed between the guide surfaces 6 a and 6 b of the side holder and the front and back surfaces of the work 1 by the fluid flowing out from the outflow holes 7 of these guide surfaces. The side part 1a of the workpiece passes between the upper and lower guide surfaces 6a and 6b while being sandwiched between the fluid films.

案内面６ａ、６ｂとワーク表面との間隙を狭く設定することにより、その間に形成される流体膜の圧力を高くすることが可能で、この高い流体圧（特に液圧）で上下面を挟持することにより、高い保持剛性と保持精度とを実現することができる。すなわち、加工するワーク１の幅寸法Ｂ（図１）が変わったとき、砥石ユニット３と側辺部ホルダ４との相対位置関係を一定にしたまま、新たなワーク幅に対応する位置に砥石ユニット３を移動させれば、側辺部ホルダ４は常に加工される位置でワークの側辺部１ａを高剛性かつ高精度で保持することとなり、テーブル２の大きさを変えることなく、幅寸法Ｂの異なるワークの側辺加工を行うことが可能になる。   By narrowing the gap between the guide surfaces 6a and 6b and the workpiece surface, it is possible to increase the pressure of the fluid film formed between them, and the upper and lower surfaces are sandwiched by this high fluid pressure (particularly fluid pressure). Thus, high holding rigidity and holding accuracy can be realized. That is, when the width dimension B (FIG. 1) of the workpiece 1 to be processed is changed, the grindstone unit is positioned at a position corresponding to the new workpiece width while keeping the relative positional relationship between the grindstone unit 3 and the side portion holder 4 constant. 3 is moved, the side holder 4 always holds the side 1a of the workpiece with high rigidity and high precision at the position where it is processed, and the width B can be changed without changing the size of the table 2. It is possible to perform side machining of different workpieces.

砥石ユニット３と側辺部ホルダ４の相対位置は、ワーク１の寸法に関わらず一定であるので、側辺部ホルダ４は図１ないし５に示すように砥石ユニット３を支持している工具側フレーム１０に装着してやればよいが、板厚の異なるワークの加工を行う場合には、上下の案内面６ａ、６ｂの位置を調整する調整装置が必要であり、また、ワーク１の着脱や旋回を行う際に案内板５ａ、５ｂ、特に下方の案内板５ｂを退避させる退避装置１１とが必要である。   Since the relative position of the grindstone unit 3 and the side edge holder 4 is constant regardless of the dimensions of the workpiece 1, the side edge holder 4 is on the tool side supporting the grindstone unit 3 as shown in FIGS. However, when processing workpieces having different thicknesses, an adjustment device that adjusts the positions of the upper and lower guide surfaces 6a and 6b is necessary. When performing, the guide plate 5a, 5b, especially the retracting device 11 which retracts the lower guide plate 5b is required.

図３に示した構造は、サーボモータ１２ａ、１２ｂで回転駆動されるボールねじ１３ａ、１３ｂによって上下の案内板５ａ、５ｂの高さ調整及び退避を行う構造で、上下の案内板５ａ、５ｂは、直線ガイド１５とスライド１６によって工具側フレーム１０に上下方向移動自在に案内されており、かつボールねじ１３ａ、１３ｂに螺合するボールナット１４ａ、１４ｂに連結されている。サーボモータ１２ａ、１２ｂ及びボールねじ１３ａ、１３ｂと直線ガイド１５は、工具側フレーム１０で支持されている。   The structure shown in FIG. 3 is a structure in which the height of the upper and lower guide plates 5a and 5b is adjusted and retracted by ball screws 13a and 13b that are rotationally driven by servo motors 12a and 12b. The linear guide 15 and the slide 16 guide the tool side frame 10 so as to be movable in the vertical direction, and are connected to ball nuts 14a and 14b which are screwed into the ball screws 13a and 13b. The servo motors 12 a and 12 b and the ball screws 13 a and 13 b and the linear guide 15 are supported by the tool side frame 10.

案内板５ａ、５ｂは、その前縁５ｃをワーク１の加工辺１ｂに近接させて配置させることが望ましい。従って、図３に示すように、案内板５ａ、５ｂを上下方向に退避させる構造では、退避したときに案内板の前縁５ｃと砥石３ａ、３ｂとが干渉する。前述した切欠９は、この案内板退避時の砥石３ａ、３ｂとの干渉を避けるためのものである。   The guide plates 5a and 5b are preferably arranged with their front edges 5c close to the machining side 1b of the workpiece 1. Therefore, as shown in FIG. 3, in the structure in which the guide plates 5a and 5b are retracted in the vertical direction, the front edge 5c of the guide plate interferes with the grindstones 3a and 3b when retracted. The notch 9 described above is for avoiding interference with the grindstones 3a and 3b when the guide plate is retracted.

退避時に砥石３ｂとの干渉を避ける他の方法は、図４に示すように、案内板５ｂを斜めに退避させる構造である。図４のものは、案内板５ａ、５ｂの高さ調整を図３と同様なボールねじ１３ａ、１３ｂで行い、かつ下方の案内板５ｂは、斜めに設けた退避シリンダ１７を介して装着されている。すなわち、図４の下側の案内板５ｂは、直線ガイド１５とスライド１６で上下方向に案内されかつボールナット１４ｂに連結された昇降台１８に、図示しない斜め方向の直線ガイドで案内され、かつ退避シリンダ１７を介して昇降台１８に連結された構造である。ワークの板厚に対する案内面６ａ、６ｂの位置調整は、ボールねじ１３ａ、１３ｂで行い、ワーク１の装脱時や旋回時には、退避シリンダ１７を縮退して下側の案内板５ｂのみを退避させる。このとき必要があれば、上側案内板５ａを砥石 ３ａと接触しない範囲で上方に退避させることもできる。もし、上側の案内板５ａの退避も必要であれば、下側と同様な構造で上側の案内板５ａにも退避シリンダを設けてやればよい。   Another method for avoiding interference with the grindstone 3b during retraction is a structure in which the guide plate 5b is retreated obliquely as shown in FIG. In FIG. 4, the height of the guide plates 5a and 5b is adjusted by the same ball screws 13a and 13b as in FIG. 3, and the lower guide plate 5b is mounted via a retracting cylinder 17 provided obliquely. Yes. That is, the lower guide plate 5b in FIG. 4 is guided by the linear guide 15 and the slide 16 in the vertical direction and is guided to the elevator 18 connected to the ball nut 14b by the diagonal guide (not shown), and The structure is connected to the lift 18 via the retraction cylinder 17. The position of the guide surfaces 6a and 6b with respect to the workpiece thickness is adjusted by the ball screws 13a and 13b. When the workpiece 1 is loaded or unloaded or turned, the retracting cylinder 17 is retracted to retract only the lower guide plate 5b. . At this time, if necessary, the upper guide plate 5a can be retracted upward within a range not contacting the grindstone 3a. If the upper guide plate 5a needs to be retracted, the upper guide plate 5a may be provided with a retracting cylinder with the same structure as the lower side.

図４は、調整用のボールねじ１３ｂとは別に、退避用のシリンダ１７を設けた例であるが、図３のボールねじ１３ａ、１３ｂを斜めに設けることによって上下の案内板５ａ、５ｂを斜め方向に退避させることができる（図５参照）。   FIG. 4 shows an example in which a retracting cylinder 17 is provided in addition to the adjustment ball screw 13b. By providing the ball screws 13a and 13b in FIG. 3 obliquely, the upper and lower guide plates 5a and 5b are inclined. Can be retracted in the direction (see FIG. 5).

退避した案内板をワーク挟持位置に復帰させるのは、ワークの加工開始端が案内面６ａ、６ｂの挟持領域に入った後である。退避位置にある案内板は、その案内面への流体の供給を開始した後、挟持位置へと進出する。テーブル２から張出して下方へ撓んだ状態になっているワーク側辺部１ａは、案内面６ｂが進出したときに、当該案内面に供給されている流体によって案内面６ｂから浮き上がった状態で正規の高さ位置に位置決めされる。このとき、上側の案内面６ａからも流体を供給しておくことが必要である。   The retracted guide plate is returned to the workpiece clamping position after the machining start end of the workpiece enters the clamping region of the guide surfaces 6a and 6b. The guide plate in the retracted position advances to the clamping position after starting the supply of fluid to the guide surface. When the guide surface 6b advances, the workpiece side portion 1a that protrudes from the table 2 and is bent downward is lifted from the guide surface 6b by the fluid supplied to the guide surface. It is positioned at the height position. At this time, it is necessary to supply fluid also from the upper guide surface 6a.

なお、テーブル２から張出した部分でのワーク側辺部１ａの垂れ下がりを極力避けたいときは、側辺部ホルダ４のワーク１の送り方向前後にベルトコンベアや空気浮上台を設けて、ワーク１の側辺部を支持してやればよい。このベルトコンベアや空気浮上台を工具側フレーム１０に搭載することにより、ワーク１の大きさが変わったときも、側辺部ホルダ４の前後の位置でワークの側辺部１ａを支持することができる。   When it is desired to avoid the hanging of the workpiece side 1a at the portion protruding from the table 2 as much as possible, a belt conveyor or an air levitation table is provided before and after the workpiece 1 is fed in the side holder 4 and the workpiece 1 What is necessary is just to support a side part. By mounting the belt conveyor and the air levitation base on the tool side frame 10, even when the size of the workpiece 1 is changed, the side portion 1 a of the workpiece can be supported at the front and rear positions of the side portion holder 4. it can.
