Description

本発明は、金属板状による被加工材（ワーク）の板面に切削加工を施す際、その板状の被加工材を位置決め保持するための被加工材保持装置及び被加工材保持方法に関する。   The present invention relates to a workpiece holding device and a workpiece holding method for positioning and holding a plate-like workpiece when cutting a plate surface of a workpiece (work) in a metal plate shape.

従来のこの種の被加工材保持装置として、例えば、特許文献１に示されるものがある。この被加工材保持装置は、断面形状がＬ字形の段差面を持つ円弧形の把持部を有する略扇状の３つのチャックが円形を成すように配置され、この３つのチャックは径方向に移動可能となっていて、各チャックの把持部で区画される空間に被加工材の一部を挿入し、３つのチャックを径の中心方向へ移動させることで、把持部により３方向から被加工材を挟みつけて保持するものとなっている。自動切削装置による切削加工の際、チャックは回転するものとなっている。   As a conventional workpiece holding device of this type, for example, there is one disclosed in Patent Document 1. This work material holding device is arranged so that three substantially fan-shaped chucks having an arc-shaped gripping portion having an L-shaped step surface in a cross section form a circle, and these three chucks move in the radial direction. It is possible to insert a part of the workpiece into the space defined by the gripping portion of each chuck, and move the three chucks in the central direction of the diameter so that the workpiece can be moved from three directions by the gripping portion. Is sandwiched and held. The chuck is rotated during cutting by the automatic cutting device.

特開２００６−３２６７４７号公報JP 2006-326747 A

しかしながら、上述した従来の技術においては、以下の問題がある。
すなわち、各チャックの把持部により被加工材（例えば、厚さ４ｍｍの金属板）を挟みつけて保持する場合、挟みつける力が弱いと、旋盤装置などの自動切削装置による切削加工の際に、チャックの回転力や切削工具により被加工材に加わる負荷により、被加工材がチャックから外れる危険があり、逆に挟みつける力が強すぎると、被加工材にたわみが生じて正確な切削ができなくなるため、被加工材を適正な力で挟みつけて保持する必要があるが、従来の被加工材保持装置では、操作者が手で被加工材を持って各チャックの把持部で区画される空間に挿入しながら、各チャックを径の中心方向へ移動させるスイッチを操作者が足踏み操作するものとなっているため被加工材を適正な力で挟みつけて保持することが難しく、操作に熟練を要するという問題がある。
本発明は、このような問題を解決することを課題とする。 However, the conventional techniques described above have the following problems.
That is, when a workpiece (for example, a metal plate having a thickness of 4 mm) is sandwiched and held by the grip portion of each chuck, if the sandwiching force is weak, when cutting by an automatic cutting device such as a lathe device, There is a risk that the workpiece will come off the chuck due to the chuck's rotational force or the load applied to the workpiece by the cutting tool. Conversely, if the clamping force is too strong, the workpiece will bend and accurate cutting will be possible. Therefore, it is necessary to sandwich and hold the workpiece with an appropriate force. In the conventional workpiece holding device, the operator holds the workpiece by hand and is partitioned by the gripping portion of each chuck. It is difficult for the operator to step and hold the switch that moves each chuck toward the center of the diameter while inserting it in the space, so it is difficult to hold the work piece with an appropriate force, and it is skilled in operation. Need There is a problem in that.
An object of the present invention is to solve such a problem.

そのため、本発明の被加工材保持装置は、径方向に移動可能な複数のチャックと、この平坦な吸引面及び吸引面で開口した吸引孔を有しかつ前記複数のチャックが成す形の中心部に位置するように設けられた、吸引治具と、前記各チャックを移動させるチャック移動手段と、前記吸引孔に接続された吸引手段を備え、前記吸引手段により前記吸引孔を介して所定の吸引力で被加工材を吸引して、該被加工材を前記吸引治具の吸引面に吸着した後、前記チャック移動手段により前記各チャックを径の中心方向へ移動させることにより、前記被加工材の外周を予め定めた力で挟み付けて被加工材を前記各チャックにより位置決めし、更に先の所定の吸引力より強い吸引力で被加工材Ｗを吸引治具に吸着して吸引面に固定保持することを特徴とする。   Therefore, the workpiece holding device of the present invention has a plurality of chucks that are movable in the radial direction, a flat suction surface, and a suction hole that opens at the suction surface, and a central portion formed by the plurality of chucks. A suction jig, a chuck moving means for moving each chuck, and a suction means connected to the suction hole. The suction means is configured to perform predetermined suction through the suction hole. The work material is sucked by force, and the work material is sucked onto the suction surface of the suction jig, and then the chuck moving means moves the chucks toward the center of the diameter, thereby the work material. The workpiece is positioned by the chucks with a predetermined force, and the workpiece W is attracted to the suction jig with a suction force stronger than the predetermined suction force and fixed to the suction surface. It is characterized by holding

このようにした本発明は、所定の吸引力で被加工材を吸引して被加工材を吸引治具の吸引面に吸着した後、各チャックを径の中心方向へ移動させることにより、被加工材Ｗの外周を予め定めた力で挟み付けて被加工材を各チャックにより位置決めし、更に先の所定の吸引力より強い吸引力で被加工材を吸引治具に吸着して吸引面に固定するようにしているため、熟練を要することなく、自動切削装置の切削工具による安定した切削加工が可能になるように被加工材Ｗを吸引治具の吸引面に確実に位置決め固定することができるという効果が得られる。   In the present invention thus configured, the workpiece is sucked to the suction surface of the suction jig by sucking the workpiece with a predetermined suction force, and then each chuck is moved toward the center of the diameter. The outer periphery of the material W is clamped with a predetermined force, the workpiece is positioned by each chuck, and the workpiece is attracted to the suction jig with a suction force stronger than the predetermined suction force and fixed to the suction surface. Therefore, the workpiece W can be reliably positioned and fixed on the suction surface of the suction jig so that stable cutting can be performed by the cutting tool of the automatic cutting device without requiring skill. The effect is obtained.

以下、図面を参照して本発明による被加工材保持装置及び被加工材保持方法の実施例を説明する。   Hereinafter, embodiments of a workpiece holding device and a workpiece holding method according to the present invention will be described with reference to the drawings.

図１は第１の実施例による被加工材保持装置を示す要部斜視図、図２はチャックを断面とした要部側面図である。図において１は円弧形の複数のチャック（把持爪）で、図１では３個示しているが、２個あるいは４個以上でも差し支えない。この複数のチャック１は同一円を成すようにかつ矢印で示したように径方向に移動可能に基台２に設けられており、基台２と共にチャック１は回転するものとなっている。   FIG. 1 is a main part perspective view showing a workpiece holding device according to the first embodiment, and FIG. 2 is a main part side view with a cross section of a chuck. In the figure, reference numeral 1 denotes a plurality of arc-shaped chucks (gripping claws). Although three are shown in FIG. 1, two or four or more may be used. The plurality of chucks 1 are provided on the base 2 so as to form the same circle and are movable in the radial direction as indicated by arrows, and the chuck 1 rotates together with the base 2.

３は吸引治具で、平坦に加工された吸引面を有し、この吸引面に開口した複数（１つでも可）の吸引孔４が設けられていて、この吸引治具３は、複数のチャック１が成す円（形）の中心部に位置するように基台２に取り付けられている。各チャック１と吸引治具３の高さつまり基台２からの突出長は、吸引治具３よりも各チャック１の方が高く（長く）なっており、その差は後述する被加工材（ワーク）の板厚以下で、被加工材に対する切削加工を妨げない寸法に設定される。
尚、基台２には、吸引治具３の吸引孔４に連通する孔が設けられている。 Reference numeral 3 denotes a suction jig, which has a flatly processed suction surface, and is provided with a plurality (or even one) of suction holes 4 opened in the suction surface. The chuck 1 is attached to the base 2 so as to be positioned at the center of a circle (shape) formed by the chuck 1. The height of each chuck 1 and the suction jig 3, that is, the protruding length from the base 2 is higher (longer) in each chuck 1 than the suction jig 3, and the difference is the workpiece (to be described later) It is set to a dimension that is equal to or less than the thickness of the workpiece) and does not hinder the cutting of the workpiece.
The base 2 is provided with a hole communicating with the suction hole 4 of the suction jig 3.

図３は第１の実施例の制御系を示すブロック図で、制御部５と、この制御部５に接続された記憶部６、チャック駆動部（チャック移動手段）７、及び吸引部（吸引手段）８を備えている。ここで制御部５は、記憶部６に記憶された制御プログラムに基づいてチャック駆動部７、及び吸引部８の動作を制御する。チャック駆動部７は制御部５の指示によりチャック１の移動を実行させるもので、チャック１の移動は油圧または空圧を用いることができる。また、吸引部８は制御部５の指示により吸引治具３の吸引孔４を介して被加工材を吸引するもので、基台２に設けられた孔を介して吸引治具３の吸引孔４に接続されており、この吸引部８としては吸引ポンプを用いることができる。   FIG. 3 is a block diagram showing the control system of the first embodiment. The control unit 5, the storage unit 6 connected to the control unit 5, the chuck driving unit (chuck moving unit) 7, and the suction unit (suction unit). ) 8 is provided. Here, the control unit 5 controls the operations of the chuck drive unit 7 and the suction unit 8 based on the control program stored in the storage unit 6. The chuck driving unit 7 causes the chuck 1 to move according to an instruction from the control unit 5, and the chuck 1 can be moved using hydraulic pressure or pneumatic pressure. The suction unit 8 sucks the workpiece through the suction hole 4 of the suction jig 3 according to an instruction from the control unit 5, and the suction hole of the suction jig 3 through the hole provided in the base 2. 4, a suction pump can be used as the suction unit 8.

上述した構成の作用について説明する。
尚、以下に説明する各部の動作は、記憶部６に格納された制御プログラムに基づいて制御部５により制御されるものとする。
図４は第１の実施例の作用を示すチャックを断面とした要部側面図で、図においてＷは被加工材で、ここでは例えば厚さ４ｍｍ程度の金属製円板とする。この被加工材Ｗを保持する場合、各チャック１の内径が被加工材Ｗの外形より大きくなるように、予め外方向つまり径の中心方向と逆の方向へ移動させておく。 The operation of the above configuration will be described.
Note that the operation of each unit described below is controlled by the control unit 5 based on a control program stored in the storage unit 6.
FIG. 4 is a side view of an essential part in which the chuck showing the operation of the first embodiment is shown in cross section. In the figure, W is a workpiece, and here, for example, a metal disc having a thickness of about 4 mm. When holding the workpiece W, the chuck 1 is moved in advance in the outward direction, that is, the direction opposite to the center direction of the diameter so that the inner diameter of each chuck 1 is larger than the outer shape of the workpiece W.

この状態で作業者は、まず被加工材Ｗを手に持ち、その板面を吸引治具３の吸引面に押し付けて図示しないスイッチをオンにする。これにより吸引部８は吸引治具３の吸引孔４を介して所定の吸引力、例えば、５０〜６０Ｋｇの吸引力で被加工材Ｗを吸引し、図４（ａ）に示したように被加工材Ｗを吸引治具３の吸引面に吸着する。   In this state, the operator first holds the workpiece W, presses the plate surface against the suction surface of the suction jig 3, and turns on a switch (not shown). As a result, the suction unit 8 sucks the workpiece W with a predetermined suction force, for example, a suction force of 50 to 60 kg, through the suction hole 4 of the suction jig 3, and as shown in FIG. The workpiece W is adsorbed on the suction surface of the suction jig 3.

このようにして被加工材Ｗを吸引治具３に吸着すると、チャック駆動部７が各チャック１を径の中心方向へ移動させ、図４（ｂ）に示したように被加工材Ｗの外周を予め定めた力、例えば２〜４ｋｇの力で挟み付ける。これにより被加工材Ｗは各チャック１により把持されると同時に位置決め（芯出し）されるので、この状態で吸引部８は吸引治具３の吸引孔４を介して先の所定の吸引力より強い吸引力、例えば、８０〜１００Ｋｇの吸引力で被加工材Ｗを吸引し、被加工材Ｗを吸引治具３に吸着して吸引面に固定保持する。   When the workpiece W is attracted to the suction jig 3 in this way, the chuck driving unit 7 moves each chuck 1 toward the center of the diameter, and the outer periphery of the workpiece W as shown in FIG. Is clamped with a predetermined force, for example, a force of 2 to 4 kg. As a result, the workpiece W is gripped by each chuck 1 and positioned (centered) at the same time. In this state, the suction portion 8 is driven by a predetermined suction force through the suction hole 4 of the suction jig 3. The workpiece W is sucked with a strong suction force, for example, a suction force of 80 to 100 kg, and the workpiece W is attracted to the suction jig 3 and fixedly held on the suction surface.

この状態では、被加工材Ｗは吸引治具３の吸引面に強く固定保持されるので、基台２と共に回転するチャック１の回転力や自動切削装置の切削工具により被加工材に加わる負荷により被加工材Ｗが吸引治具３から外れることはなく、また被加工材Ｗが各チャック１の挟む力により撓むこともないので、自動切削装置の切削工具による安定した切削加工が可能になる。   In this state, the workpiece W is strongly fixed and held on the suction surface of the suction jig 3, and therefore, due to the rotational force of the chuck 1 rotating together with the base 2 and the load applied to the workpiece by the cutting tool of the automatic cutting device. Since the workpiece W is not detached from the suction jig 3 and the workpiece W is not bent by the force sandwiched between the chucks 1, stable cutting by the cutting tool of the automatic cutting apparatus is possible. .

以上説明したように、第１の実施例では、所定の吸引力で被加工材Ｗを吸引して被加工材Ｗを吸引治具３の吸引面に吸着した後、各チャック１を径の中心方向へ移動させることにより、被加工材Ｗの外周を予め定めた力で挟み付けて被加工材Ｗを各チャック１により位置決めし、更に先の所定の吸引力より強い吸引力で被加工材Ｗを吸引治具３に吸着して吸引面に固定するようにしているため、熟練を要することなく、自動切削装置の切削工具による安定した切削加工が可能になるように被加工材Ｗを吸引治具３に吸引面に確実に位置決め固定することができるという効果が得られる。   As described above, in the first embodiment, the workpiece W is attracted to the suction surface of the suction jig 3 by sucking the workpiece W with a predetermined suction force, and then each chuck 1 is centered on the diameter. By moving in the direction, the outer periphery of the workpiece W is sandwiched with a predetermined force, the workpiece W is positioned by each chuck 1, and further, the workpiece W with a suction force stronger than a predetermined suction force ahead. Is sucked onto the suction jig 3 and fixed to the suction surface, so that the workpiece W is suction-treated so that stable cutting can be performed with a cutting tool of an automatic cutting device without requiring skill. The effect that the tool 3 can be reliably positioned and fixed to the suction surface is obtained.

尚、上述した実施例では、被加工材Ｗの保持に当り、操作者が被加工材Ｗの板面を吸引治具３の吸引面に押し付けてスイッチをオンにすることにより吸引部８が吸引治具３の吸引孔４を介して所定の吸引力で被加工材Ｗを吸引するものとしたが、被加工材Ｗの板面を吸引治具３の吸引面に押し付けたことを自動検知するセンサを設けて、このセンサのオンにより吸引部８が吸引治具３の吸引孔４を介して所定の吸引力で被加工材Ｗを吸引するように構成することも可能である。
また、チャック１の形状を変えることにより、被加工材Ｗは円板状に限らず、他の形状のものでも固定保持可能であり、また被加工材Ｗは、磁性、非磁性に限らず高精度の寸法だしが可能である。 In the above-described embodiment, when the workpiece W is held, the operator presses the plate surface of the workpiece W against the suction surface of the suction jig 3 and turns on the switch so that the suction portion 8 sucks. Although the workpiece W is sucked with a predetermined suction force through the suction hole 4 of the jig 3, it is automatically detected that the plate surface of the workpiece W is pressed against the suction surface of the suction jig 3. It is also possible to provide a sensor so that when the sensor is turned on, the suction part 8 sucks the workpiece W with a predetermined suction force through the suction hole 4 of the suction jig 3.
In addition, by changing the shape of the chuck 1, the workpiece W is not limited to a disc shape, and can be fixedly held in other shapes. Accurate dimensioning is possible.
