Description

本発明は、ＮＣ工作機械等による切削加工時に被切削物を載置するために用いられる治具板に関するものである。   The present invention relates to a jig plate used for placing an object to be cut during cutting with an NC machine tool or the like.

図４〜図６に示すように、プリント基板等の被加工物１に穴明け加工を行う際や、当該被切削物１から個々の基板等を切り出す際に用いられるＮＣルーター等の工作機械２においては、被切削物１の下面側に、予め治具板３が設置されている（下記特許文献１、２を参照）。   As shown in FIGS. 4 to 6, a machine tool 2 such as an NC router used when drilling a workpiece 1 such as a printed circuit board or cutting an individual substrate from the workpiece 1. , A jig plate 3 is previously installed on the lower surface side of the workpiece 1 (see Patent Documents 1 and 2 below).

この治具板３は、ピン４等によって工作機械２の基板５上に位置決めされて設置され、この治具板３上に、上記ピン４等を利用して被切削物１が載置されるもので、被切削物１がドリルやエンドミル等の工具６によって切削加工される際に、その表面まで削り込まれることにより、上記被切削物１にバリが生じることを防止するものである。   The jig plate 3 is positioned and installed on the substrate 5 of the machine tool 2 by pins 4 or the like, and the workpiece 1 is placed on the jig plate 3 using the pins 4 or the like. Therefore, when the workpiece 1 is cut by a tool 6 such as a drill or an end mill, the surface of the workpiece 1 is cut to the surface, thereby preventing burrs from being generated on the workpiece 1.

ところで、従来、このような治具板３としては、被切削物１に密着して高い面精度を保持させる必要があるとともに、切削加工時には所定の圧縮強度およびせん断強度が要求されることから、もっぱら表面の平滑度や平面度に優れるとともに剛性の高い紙フェノール製の板材が用いられていた。   By the way, conventionally, as such a jig plate 3, it is necessary to maintain high surface accuracy by being in close contact with the workpiece 1, and at the time of cutting, a predetermined compressive strength and shear strength are required. A board material made of paper phenol having excellent surface smoothness and flatness and having high rigidity has been used.

特開２００１−７４８２号公報JP 2001-7482 A 特開２００２−２３３９０６号公報JP 2002-233906 A

しかしながら、従来の治具板３は、例えば700mm×557mm×15mm程度の寸法を有するものであり、しかも上記紙フェノール製板材の比重は１．３〜１．４であるため、重量が嵩み、その取り付けおよび取り外し時におけるハンドリングに多くの労力を要するという問題点があった。   However, the conventional jig plate 3 has a dimension of, for example, about 700 mm × 557 mm × 15 mm, and the specific gravity of the paper phenol plate material is 1.3 to 1.4. There has been a problem that a lot of labor is required for handling at the time of attachment and removal.

加えて、上記治具板３は、被切削物１に対する切削加工に伴って、その表面に多数条の溝が形成されてしまうため、通常、両面において被切削物１の切削加工を行った後は廃棄処分されている。このため、比較的高価で、かつ重量も大きな治具板３にあっては、廃棄コストも嵩んで経済性に劣るという問題点もあった。   In addition, since a plurality of grooves are formed on the surface of the jig plate 3 as the workpiece 1 is cut, usually after the workpiece 1 is cut on both sides. Has been disposed of. For this reason, the jig plate 3 which is relatively expensive and heavy in weight has a problem that it is inferior in economic efficiency due to high disposal costs.

本発明は、上記事情に鑑みてなされたものであり、軽量であって取扱が容易であるとともに所望の機械的強度を備え、かつ廃棄処分も低コストで行うことができて経済性に優れる治具板を提供することを課題とするものである。   The present invention has been made in view of the above circumstances, is light and easy to handle, has a desired mechanical strength, can be disposed of at low cost, and has excellent economic efficiency. It is an object to provide a tool plate.

上記課題を解決するため、請求項１に記載の本発明に係る治具板は、低比重木材からなり、導管方向に直交する方向から切断されて木口面が両板面とされた平板状の芯材と、この芯材の少なくとも一方の上記木口面側に貼り付けられた紙フェノール製板材とを有してなることを特徴とするものである。   In order to solve the above problems, a jig plate according to the present invention described in claim 1 is made of low specific gravity wood and is cut in a direction perpendicular to the direction of the conduit, and has a flat plate shape in which the end surfaces are both plate surfaces. It is characterized by comprising a core material and a paper phenol plate material attached to at least one of the core surfaces of the core material.

また、請求項２に記載の発明は、請求項１に記載の発明において、上記芯材の両方の上記木口面側に、上記紙フェノール製板材が貼り付けられていることを特徴とするものである。   The invention according to claim 2 is characterized in that, in the invention according to claim 1, the paper phenol plate material is pasted to the both ends of the core material. is there.

さらに、請求項３に記載の発明は、請求項１または２に記載の発明において、上記木口面にメラミン樹脂製板材が貼り付けられ、当該メラミン樹脂製板材の表面に上記紙フェノール製板材が貼り付けられていることを特徴とするものである。   Furthermore, the invention according to claim 3 is the invention according to claim 1 or 2, wherein a melamine resin plate material is attached to the end of the lip, and the paper phenol plate material is attached to the surface of the melamine resin plate material. It is characterized by being attached.

また、請求項４に記載の発明は、請求項１〜３のいずれかに記載の発明において、上記低比重木材は、バルサ材、ファルカタ材または桐材であることを特徴とするものである。   The invention according to claim 4 is the invention according to any one of claims 1 to 3, wherein the low specific gravity wood is a balsa material, a Falkata material, or a paulownia material.

請求項１〜４のいずれかに記載の発明によれば、内部に軽量な低比重木材からなる芯材を設け、この芯材の少なくとも被切削物が載置される一方の木口面側に、従来の治具板と同様の紙フェノール製板材を貼り付けているために、従来の治具板と比較して軽量化を図ることができる。   According to the invention described in any one of claims 1 to 4, a core material made of light low specific gravity wood is provided inside, and at least one cut end of the core material on which the workpiece is placed, Since the same paper phenol plate material as that of the conventional jig plate is attached, the weight can be reduced as compared with the conventional jig plate.

しかも、上記芯材は、導管方向に直交する方向から切断され、その木口面に上記紙フェノール製板材が貼り付けられているために、上記導管によって治具板に作用する圧縮応力およびせん断応力に抗するための所望の剛性を得ることができ、かつ表面の紙フェノール製板材によって、被切削物に密着して高い面精度を保持するための平滑度や平面度を得ることができる。   In addition, the core material is cut from a direction orthogonal to the conduit direction, and the paper phenol plate material is attached to the end of the end of the core material. Therefore, the core material is subjected to compressive stress and shear stress acting on the jig plate by the conduit. The desired rigidity for resisting can be obtained, and smoothness and flatness for maintaining high surface accuracy by being in close contact with the workpiece can be obtained by the paper phenol plate material on the surface.

ここで、上記芯材の一方の木口面にのみ紙フェノール製板材を貼設した場合には、治具板として反りが生じやすい構造となる。このため、上記治具板が、工作機械の基板上に鉛直方向についても万力等によって拘束されて取り付けられる場合等においては、上記反りを矯正して上記紙フェノール製板材上に載置された被切削物の加工に用いることができる。   Here, when a paper phenol plate is pasted only on one end face of the core material, a warp is easily generated as a jig plate. For this reason, when the jig plate is mounted on the substrate of the machine tool by being restrained by a vise or the like in the vertical direction, the warp is corrected and placed on the paper phenol plate. It can be used for processing a workpiece.

これに対して、上記治具板を鉛直方向に拘束することなく基板上に取り付ける場合や、被切削物の載置面において高い平面度が要求される場合に用いる場合には、請求項２に記載の発明のように、上記芯材の両方の木口面に紙フェノール製板材を貼り付ければ、治具板としての厚さ寸法の精度を確保することができ、よって水平方向の位置決めのみによって上記基台上に取り付けることができるとともに、その両面を被切削物の加工に用いることができて経済性にも優れる。   On the other hand, when the jig plate is mounted on the substrate without being constrained in the vertical direction, or when high flatness is required on the placement surface of the work, As in the described invention, if a paper phenol plate is pasted on both ends of the core material, the accuracy of the thickness dimension as a jig plate can be ensured, and therefore only by horizontal positioning. While being able to attach to a base, both surfaces can be used for the process of a to-be-cut object, and it is excellent also in economical efficiency.

また、上記芯材の製作過程において、一般的に低比重木材は、導管に直交する方向から切断して板状に形成する際に上記木口面の平面度を確保することが難しい。他方、上記芯材に紙フェノール製板材を貼り付けた後に、この紙フェノール製板材の表面を切削加工して表面の平面度を確保しようとすると、当該切削加工によって表面の平滑度が損なわれてしまう。   Further, in the process of manufacturing the core material, it is generally difficult to ensure the flatness of the mouth end surface when the low specific gravity wood is cut into a plate shape from a direction orthogonal to the conduit. On the other hand, after attaching a paper phenol plate material to the core material, if the surface of the paper phenol plate material is cut to ensure surface flatness, the smoothness of the surface is impaired by the cutting process. End up.

このため、治具板として厚さ寸法に高い精度が要求される場合には、請求項３に記載の発明のように、先ず芯材の木口面にメラミン樹脂製板材を貼り付け、このメラミン樹脂製板材の表面に紙フェノール製板材を貼り付ける構造にすれば、芯材に貼り付けたメラミン樹脂製板材の表面を平坦に加工した後に、当該メラミン樹脂製板材上に紙フェノール製板材を貼り付けることにより、全体として高い厚さ寸法精度を得ることが可能になる。   For this reason, when high accuracy is required for the thickness dimension as a jig plate, first, a melamine resin plate is pasted on the end of the core material as in the invention according to claim 3, and the melamine resin With a structure in which a paper phenol board is pasted on the surface of the board, the paper phenol board is pasted on the melamine resin board after flattening the surface of the melamine resin board pasted on the core. This makes it possible to obtain high thickness dimensional accuracy as a whole.

なお、上記芯材に用いる低比重木材としては、請求項４に記載の発明のように、バルサ材、ファルカタ材または桐材が好適である。特に、バルサ材は、吸水量が多い木材であり、よって乾燥後における導管の断面積が大きく、比重も０．１〜０．５程度と小さい割に圧縮強度が高いために、従来と比較して治具板としての重量を約１／３に低減することが可能になる。   In addition, as low specific gravity wood used for the said core material, a balsa material, a Falkata material, or a paulownia material is suitable like the invention of Claim 4. In particular, balsa wood is a wood that absorbs a lot of water, so the cross-sectional area of the conduit after drying is large, and the specific gravity is as small as about 0.1 to 0.5. Thus, the weight of the jig plate can be reduced to about 1/3.

図１〜図３は、本発明に係る治具板を、ＮＣルーターに設置されてプリント基板から各々の基板を切り出す際に用いる治具板に適用した一実施形態を示すものである。
この治具板１０においては、板厚方向の中間部分に芯材１１が用いられている。この芯材１１は、バルサ材をその導管１２の方向に対して直交する方向に切断して平板状に加工したもので、上記導管１２が開口する木口面１３によって幅広の両面が形成されている。 1 to 3 show an embodiment in which a jig plate according to the present invention is applied to a jig plate installed in an NC router and used when cutting out each substrate from a printed board.
In the jig plate 10, a core material 11 is used at an intermediate portion in the plate thickness direction. The core material 11 is obtained by cutting a balsa material in a direction perpendicular to the direction of the conduit 12 and processing it into a flat plate shape. Both sides of the core material 11 are widened by a mouth end surface 13 where the conduit 12 opens. .

そして、これら木口面１３に、それぞれメラミン樹脂製板材１４が貼り付けられている。さらに、メラミン樹脂製板材１４の表面には、紙フェノール製板材１５が貼り付けられている。   And the melamine resin board | plate material 14 is affixed on these end surfaces 13, respectively. Furthermore, a paper phenol plate 15 is attached to the surface of the melamine resin plate 14.

ここで、上記構成からなる治具板１０は、例えば従来と同様の700mm×557mm×15mmの寸法に形成する場合に、メラミン樹脂製板材１４の厚さ寸法は、約1.2mmであり、紙フェノール製板材１５の厚さ寸法は、約3mmである。   Here, when the jig plate 10 having the above-described configuration is formed to have a size of 700 mm × 557 mm × 15 mm, for example, as in the conventional case, the thickness of the melamine resin plate material 14 is about 1.2 mm, and the paper phenol The thickness of the plate material 15 is about 3 mm.

上記治具板１０を製造するには、先ず複数本のバルサ材の角材１６を互いに側面同士を接着することにより一体化し、次いで各角材１６の軸線方向と直交する水平方向、すなわち各角材１６における導管１２の延在方向と直交する方向に切断して、平板状の芯材１１を作成する。   In order to manufacture the jig plate 10, first, a plurality of balsa square members 16 are integrated by adhering the side surfaces to each other, and then in the horizontal direction orthogonal to the axial direction of each square member 16, that is, in each square member 16. The flat core material 11 is formed by cutting in a direction perpendicular to the extending direction of the conduit 12.

次いで、得られた芯材１１の木口面１３をサンダーで切削研磨して表面を均一化した後に、両木口面１３にそれぞれメラミン樹脂製板材１４を貼り付ける。この際に、木口面１３に供給された接着剤の一部が、導管１２内に入り込むことにより、メラミン樹脂製板材１４が芯材１１に強固に貼り付けられる。   Next, the wood end surface 13 of the obtained core material 11 is cut and polished with a sander to make the surface uniform, and then a melamine resin plate material 14 is attached to both the end surfaces 13 respectively. At this time, a part of the adhesive supplied to the end surface 13 enters the conduit 12, whereby the melamine resin plate 14 is firmly attached to the core 11.

このようにして得られた芯材１１とメラミン樹脂製板材１４との複合材においては、芯材１１を切削加工した後の木口面１３における厚さ寸法のバラツキがそのまま残っている。一方、プリント基板の切削加工に用いる場合には、治具板１０としての厚さ寸法の交差を0.5mm以下にすることが要求されている。   In the composite material of the core material 11 and the melamine resin plate material 14 obtained in this way, the variation in the thickness dimension on the mouth end surface 13 after the core material 11 is cut remains. On the other hand, when used for cutting a printed circuit board, it is required that the intersection of thickness dimensions as the jig plate 10 be 0.5 mm or less.

そこで次に、上記メラミン樹脂製板材１４の表面を切削研磨して、上記複合材の厚さ寸法を上記公差以内に調整した後に、上記メラミン樹脂製板材１４の表面に紙フェノール製板材１５を貼り付けることにより、上記治具板１０が得られる。   Then, after the surface of the melamine resin plate material 14 is cut and polished to adjust the thickness of the composite material within the tolerance, the paper phenol plate material 15 is pasted on the surface of the melamine resin plate material 14. By attaching, the jig plate 10 is obtained.

以上説明したように、上記構成からなる治具板１０によれば、内部に比重が０．１〜０．５程度と小さいバルサ材からなる芯材１１を設けるとともに、この芯材１１の木口面１３に、それぞれメラミン樹脂製板材１４を貼り付け、さらに当該メラミン樹脂製板材１４の表面に平滑度に優れる紙フェノール製板材１５を貼り付けているために、従来の治具板と比較してその重量を約１／３に軽量化することができる。   As described above, according to the jig plate 10 having the above-described configuration, the core material 11 made of a balsa material having a specific gravity as small as about 0.1 to 0.5 is provided inside, and the wood end surface of the core material 11 13 is bonded with a melamine resin plate material 14 and a paper phenol plate material 15 having excellent smoothness on the surface of the melamine resin plate material 14. The weight can be reduced to about 1/3.

また、上記芯材１１は、導管１２の延在方向に直交する方向から切断され、その木口面１３側にメラミン樹脂製板材１４および紙フェノール製板材１５が貼り付けられているために、上記導管１２によって治具板１０に作用する圧縮応力およびせん断応力に抗するための所望の剛性を得ることができる。   Further, the core material 11 is cut from a direction orthogonal to the extending direction of the conduit 12, and the melamine resin plate material 14 and the paper phenol plate material 15 are attached to the end surface 13 side of the core material 11. The desired rigidity for resisting the compressive stress and the shear stress acting on the jig plate 10 can be obtained.

さらに、芯材１１の木口面１３にメラミン樹脂製板材１４を貼り付け、当該メラミン樹脂製板材１４の表面を平坦に加工した後に、当該メラミン樹脂製板材上に紙フェノール製板材を貼り付けているとともに、芯材１１の両方の木口面１３に、それぞれメラミン樹脂製板材１４および紙フェノール製板材１５を貼り付けているために、反りが無く、かつ高い厚さ寸法精度を得ることができる。   Further, after a melamine resin plate 14 is pasted on the wood end surface 13 of the core material 11 and the surface of the melamine resin plate 14 is processed to be flat, a paper phenol plate is pasted on the melamine resin plate. At the same time, since the melamine resin plate material 14 and the paper phenol plate material 15 are attached to both the end surfaces 13 of the core material 11, respectively, there is no warp and high thickness dimensional accuracy can be obtained.

しかも、被切削物であるプリント基板の載置面を、従来と同様の紙フェノール製板材１５としているために、上記プリント基板に密着して高い面精度を保持するための所望の平滑度や平面度を得ることができる。   And since the mounting surface of the printed board which is a to-be-cut object is made into the paper phenol board | plate material 15 similar to the past, the desired smoothness and flatness for closely_contact | adhering to the said printed board and maintaining high surface accuracy You can get a degree.

なお、上記実施形態においては、芯材１１となる低比重木材として、バルサ材を用いた場合に付いて説明したが、本発明はこれに限定されるものではなく、例えばファルカタ材や桐材等の他の低比重木材を用いることもできる。   In addition, in the said embodiment, although attached about the case where a balsa material was used as the low specific gravity wood used as the core material 11, this invention is not limited to this, For example, a Falkata material, a paulownia material, etc. Other low specific gravity wood can also be used.
