Description

本発明は、レーザー発振器を備えた帯のこ盤、卓上丸のこなどの切断機に関するものである。 The present invention relates to a cutting machine such as a band saw board or a tabletop saw having a laser oscillator.

従来、切断刃物部側にレーザー発振器を設け、切断材料の切断位置に切断刃物の切断位置を示すレーザー光を照射して切断位置と切断刃物の位置決めをする切断機として、例えば実開昭６２−１５００１９号公報がある。しかし、レーザー発振器は切断刃物部に固定されているため、レーザー光が切断刃物の切断位置からずれた場合、正確な切断位置を合わせることができなかった。 Conventionally, as a cutting machine in which a laser oscillator is provided on the side of a cutting blade and a laser beam indicating the cutting position of the cutting blade is irradiated to the cutting position of the cutting material to position the cutting position and the cutting blade, for example, No. 150019. However, since the laser oscillator is fixed to the cutting blade portion, when the laser beam is deviated from the cutting position of the cutting blade, the accurate cutting position cannot be adjusted.

従来のレーザー発振器の位置合わせ機構について、図１６〜図１８を用いて説明する。円柱形状のレーザー発振器７０を支持部材７１に止めねじ７２で押圧保持し、支持部材７１をベース７３にボルト７４で固定する。ボルト７４の固定穴は一方が丸穴７６で、他方が長穴７７となっている。 A conventional laser oscillator alignment mechanism will be described with reference to FIGS. A cylindrical laser oscillator 70 is pressed and held on a support member 71 with a set screw 72, and the support member 71 is fixed to a base 73 with bolts 74. One fixing hole of the bolt 74 is a round hole 76 and the other is a long hole 77.

図１６に示す基準位置Ｙにレーザー光Ｌを合わせる場合は、止めねじ７２を緩めレーザー発振器７０を回転させ、基準位置Ｙに一致した状態で止めねじ７２を締付けレーザー発振器７０を固定する。さらに、図１７に示す基準位置Ｘにレーザー光Ｌを合わせる場合は、ボルト７４を緩め丸穴７６を基準とし支持部材７１を水平回転させ、基準位置Ｘに一致した状態でボルト７４を締付け、支持部材７１を固定していた。 When the laser beam L is aligned with the reference position Y shown in FIG. 16, the set screw 72 is loosened and the laser oscillator 70 is rotated, and the set screw 72 is tightened and the laser oscillator 70 is fixed in a state where it matches the reference position Y. Further, when the laser beam L is aligned with the reference position X shown in FIG. 17, the bolt 74 is loosened, the support member 71 is rotated horizontally with the round hole 76 as a reference, and the bolt 74 is tightened and supported in a state where it coincides with the reference position X. The member 71 was fixed.

しかし、止めねじ７２のねじ先端は完全な平面でないため、レーザー発振器７０を止めねじ７２で締付けることになり、レーザー発振器７０の位置合わせ時にレーザー発振器７０が動く場合があり、正確にレーザー光Ｌの位置を合わせるまでには何度かこの作業を繰り返す必要があった。また、ボルト７４を締付ける場合においても、支持部材７１やボルト７４の座面の傾きなどにより、ボルト７４を締付けるため作業時に支持部材７１が動く場合があるため、同じく正確な位置に合わせられるまで何度かこの作業も繰り返す必要があった。 However, since the screw tip of the set screw 72 is not a perfect plane, the laser oscillator 70 is tightened with the set screw 72, and the laser oscillator 70 may move when the laser oscillator 70 is aligned. It was necessary to repeat this work several times before aligning the positions. Also, when tightening the bolt 74, the support member 71 may move during the operation for tightening the bolt 74 due to the inclination of the support member 71 or the seating surface of the bolt 74. This work had to be repeated several times.

本発明の目的は、上記した従来の欠点をなくし、切断刃物の切断位置に対するレーザー光の位置合わせを簡便かつ正確にすることである。 An object of the present invention is to eliminate the above-mentioned conventional drawbacks and to make the alignment of laser light with respect to the cutting position of a cutting blade simple and accurate.

上記目的は、レーザー発振器を収納する支持部材を設けると共に、支持部材に、ねじ部材をねじ嵌合させ、該ねじ部材の先端がレーザー発振器の側面と当接可能とし、ねじ部材の回転によってレーザー発振器が揺動するようにすることにより達成される。 The object is to provide a support member for housing the laser oscillator, and to screw the screw member into the support member so that the tip of the screw member can come into contact with the side surface of the laser oscillator. Is achieved by allowing the to oscillate.

本発明によれば、ねじ部材の回転でレーザー発振器を微動させることできる。よって、レーザー光の微調整をすることができ、切断位置に対するレーザー光の位置合わせを簡便かつ正確にできる。。 According to the present invention, the laser oscillator can be finely moved by the rotation of the screw member. Therefore, the laser beam can be finely adjusted, and the laser beam can be easily and accurately aligned with the cutting position. .

A cutting blade body 8 is pivotally supported above the holder 5 via a shaft 7 so as to be swingable up and down with respect to the upper surface of the base 1. A spring 9 is provided between the holder 5 and the cutting blade body 8 to urge the cutting blade body 8 upward.

切断刃物本体８は切断刃物軸１６、切断刃物１０、切断刃物１０の上半部を覆うのこカバー１１と一体となっているギヤケース１２、切断刃物１０を回転駆動するモートル１３、モートル１３のモートル軸１４、伝達ベルト２３、モートル１３及びモートル軸１４を覆い支持するモートルハウジング１５、ハンドル２６で構成されている。 The cutting blade body 8 includes a cutting blade shaft 16, a cutting blade 10, a gear case 12 integrated with a saw cover 11 covering the upper half of the cutting blade 10, a motor 13 that rotationally drives the cutting blade 10, and a motor of the motor 13.

図４において、ギヤケース１２の下方には、水平方向に切断刃物軸１６を設け、切断刃物軸１６は軸受１７，１８で回転自在に支持され、この切断刃物軸１６の一端にボルト１９で切断刃物１０を固定し、切断刃物軸１６に動力を伝達するプーリ２０を設けている。ギヤケース１２上方にはモートルハウジング１５が設けられ、その内部に切断刃物１０を回転駆動するモートル１３が備えられている。軸受２１で回転自在に支持されたモートル１３のモートル軸１４の先端には、プーリ２２がプーリ２０の上方に位置するように設けられている。このプーリ２０，２２間に伝達ベルト２３を張り渡している。この伝達ベルト２３によりモートル１３の動力は、モートル軸１４からプーリ２２、伝達ベルト２３、プーリ２０、切断刃物軸１６を介し切断刃物１０に伝達されている。 In FIG. 4, a cutting blade shaft 16 is provided in the horizontal direction below the gear case 12, and the cutting blade shaft 16 is rotatably supported by bearings 17 and 18, and a cutting blade with a bolt 19 at one end of the cutting blade shaft 16. 10 is fixed, and a pulley 20 for transmitting power to the cutting blade shaft 16 is provided. A motor housing 15 is provided above the gear case 12, and a motor 13 that rotationally drives the cutting blade 10 is provided therein. A pulley 22 is provided above the pulley 20 at the tip of the motor shaft 14 of the motor 13 that is rotatably supported by the bearing 21. A transmission belt 23 is stretched between the pulleys 20 and 22. The power of the motor 13 is transmitted from the motor shaft 14 to the cutting blade 10 via the pulley 22, the transmission belt 23, the pulley 20, and the cutting blade shaft 16 by the transmission belt 23.

ホルダ５の前面にはＶ字状の突起部５ｂが装着され、ターンテーブル２上面後方には突起部５ｂの移動軌跡上に位置するようにストッパボルト２４，２５が直角方向にねじ嵌合している。ホルダ５を傾斜させると、所定の傾斜角度で突起部５ｂがストッパボルト２４又はストッパボルト２５の頭部に係合し、切断刃物本体８の傾斜位置を設定する。通常、ストッパボルト２４，２５は、ホルダ５が左右方向に４５度の位置に傾斜したときに突起部５ｂに係合するように設けられている。 A V-shaped protrusion 5b is mounted on the front surface of the holder 5, and stopper bolts 24 and 25 are screwed in a perpendicular direction so as to be positioned on the movement locus of the protrusion 5b on the rear surface of the turntable 2. Yes. When the holder 5 is tilted, the projection 5b is engaged with the head of the stopper bolt 24 or the stopper bolt 25 at a predetermined tilt angle, and the tilt position of the cutting blade body 8 is set. Normally, the stopper bolts 24 and 25 are provided so as to engage with the protrusion 5b when the holder 5 is inclined at a 45 degree position in the left-right direction.

ターンテーブル２の上面には、中央に切断刃物１０が侵入する溝部を有する図示しない刃口板が固定され、切断材料６２切断時、切断刃物１０の下端がターンテーブル２上面よりも下降したとき、前記刃口板の溝部に侵入し、切断材料６２の仕上面へのけば立ちを防止する役目を果たしている。 On the upper surface of the turntable 2 is fixed a blade plate (not shown) having a groove part into which the cutting blade 10 enters in the center, and when the cutting material 62 is cut, when the lower end of the cutting blade 10 is lowered from the upper surface of the turntable 2, It plays the role of preventing the cutting material 62 from standing on the finished surface by entering the groove portion of the blade plate.

図３において、ホルダ５の前面に支持部材３２を固定する。図５に示すように支持部材３２中央に矩形の凹部３３を有し、凹部３３内に矩形のレーザー発振器３０が収納されている。支持部材３２は切断刃物部８が上限位置にあるとき、レーザー発振器３０から照射されるレーザー光Ｌが切断刃物１０の下方を通過する位置に設けられている。なお、レーザー発振器３０には図示していないが、レーザー光Ｌを照射するためのスイッチを設けている。本実施形態では、レーザー発振器３０のレーザー光Ｌの照射部３０ｂは、切断刃物１０の刃先１０ａの延長線上に位置している。 In FIG. 3, the support member 32 is fixed to the front surface of the holder 5. As shown in FIG. 5, a rectangular recess 33 is provided at the center of the support member 32, and the rectangular laser oscillator 30 is accommodated in the recess 33. The support member 32 is provided at a position where the laser light L emitted from the laser oscillator 30 passes below the cutting blade 10 when the cutting blade portion 8 is at the upper limit position. Although not shown, the laser oscillator 30 is provided with a switch for irradiating the laser beam L. In this embodiment, the irradiation part 30b of the laser beam L of the laser oscillator 30 is located on an extension line of the cutting edge 10a of the cutting blade 10.

図６において、支持部材３２の凹部３３内の左側面前端部に半球形凹部３３ａと、レーザー発振器３０の左側面前端部に半球形凹部３０ａが各々形成されている。半球形凹部３３ａと半球形凹部３０ａに球３４を嵌合させ、球３４を支点にレーザー発振器３０が凹部３３内で揺動自在となる。凹部３３の半球形凹部３３ａの後方に第１ストッパ３５をねじ嵌合させ、第１ストッパ３５の先端をレーザー発振器３０の左側面後端部に当接させる。レーザー発振器３０の半球形凹部３０ａの反対の側面と凹部３３側面との間にレーザー発振器３０を第１ストッパ３５側へ押圧する圧縮バネ３６を保持している。支持部材３２の下面に第２ストッパ３７をねじ嵌合させ、第２ストッパ３７は球３４の反対側（図６の右端）で、かつほぼ中央（図７参照）に位置し、第２ストッパ３７の先端はレーザー発振器３０の下面に当接している。レーザー発振器３０の上面と支持部材３２との間にレーザー発振器３０を第２ストッパ３７側へ押圧する圧縮バネ３８を保持している。圧縮バネ３８は図７に示すように第２ストッパ３７と対向し、第２ストッパ３７を中心に左右に１個ずつ配置させることで、レーザー発振器３０のバランスを保っている。 In FIG. 6, a hemispherical recess 33 a is formed at the front end of the left side surface in the recess 33 of the support member 32, and a hemispherical recess 30 a is formed at the front end of the left side surface of the laser oscillator 30. The sphere 34 is fitted into the hemispherical recess 33 a and the hemispherical recess 30 a, and the laser oscillator 30 can swing within the recess 33 with the sphere 34 as a fulcrum. The first stopper 35 is screwed behind the hemispherical concave portion 33 a of the concave portion 33, and the front end of the first stopper 35 is brought into contact with the rear end portion of the left side surface of the laser oscillator 30. A compression spring 36 that presses the laser oscillator 30 toward the first stopper 35 is held between the side surface opposite to the hemispherical recess 30 a of the laser oscillator 30 and the side surface of the recess 33. A second stopper 37 is screwed onto the lower surface of the support member 32. The second stopper 37 is located on the opposite side of the ball 34 (right end in FIG. 6) and substantially in the center (see FIG. 7). The tip of is in contact with the lower surface of the laser oscillator 30. A compression spring 38 that presses the laser oscillator 30 toward the second stopper 37 is held between the upper surface of the laser oscillator 30 and the support member 32. As shown in FIG. 7, the compression spring 38 faces the second stopper 37 and is arranged one by one on the left and right with the second stopper 37 as the center to maintain the balance of the laser oscillator 30.

上記構成において、第１ストッパ３５を回転して右方向に移動させると、レーザー発振器３０の左側面後端部を押し、レーザー発振器３０は球３４を支点に図５において時計方向に回転し、レーザー光Ｌは左に傾く方向に照射される。このとき、第１ストッパ３５を１回転させたときのレーザー発振器３０の移動量は第１ストッパ３５のねじのリードだけとなり、レーザー発振器３０を微動させることができる。第１ストッパ３５を左方向に移動させると、圧縮バネ３６の復元力により球３４を支点に図５において反時計方向に回転し、レーザー光Ｌは右に傾く方向に照射される。レーザー光Ｌの水平方向の位置を基準位置Ｘに合わせるには、第１ストッパ３５を回転して左右方向に移動させ、レーザー光Ｌが基準位置Ｘと一致したところで第１ストッパ３５を止める。これで、レーザー光Ｌの水平方向の位置が設定される。 In the above configuration, when the first stopper 35 is rotated and moved in the right direction, the rear end of the left side surface of the laser oscillator 30 is pushed, and the laser oscillator 30 rotates clockwise in FIG. The light L is emitted in a direction tilted to the left. At this time, the amount of movement of the laser oscillator 30 when the first stopper 35 is rotated once is only the lead of the screw of the first stopper 35, and the laser oscillator 30 can be finely moved. When the first stopper 35 is moved leftward, the restoring force of the compression spring 36 rotates counterclockwise in FIG. 5 with the ball 34 as a fulcrum, and the laser beam L is irradiated in a direction inclined to the right. In order to align the horizontal position of the laser beam L with the reference position X, the first stopper 35 is rotated and moved in the left-right direction, and the first stopper 35 is stopped when the laser beam L coincides with the reference position X. Thus, the horizontal position of the laser beam L is set.

次に、第２ストッパ３７を回転して上方向に移動させると、レーザー発振器３０の下面右端部を押し、レーザー発振器３０は球３４を支点に図６において反時計方向に回転し、レーザー光Ｌは図８において左に傾く方向に照射される。第２ストッパ３７を下方向に移動させると、圧縮バネ３８の復元力により球３４を支点に図６において時計方向に回転し、レーザー光Ｌは右に傾く方向に照射される。図８に示すようにレーザー光Ｌの直角方向の位置を基準位置Ｙに合わせるには第２ストッパ３７を回転して上下に移動させ、レーザー光Ｌが基準位置Ｙと一致したところで第２ストッパ３７を止める。これで、レーザー光Ｌの直角方向の位置が設定される。第２ストッパ３７を１回転させたときのレーザー発振器３０の移動量は第２ストッパ３７のねじのリードだけとなり、レーザー発振器３０を上下に微動させることがてきる。上記設定により、レーザー発振器３０のレーザー光Ｌは、切断刃物本体８を下方に揺動したときの切断刃物１０の切断位置を示すことになる。 Next, when the second stopper 37 is rotated and moved upward, the lower right end of the laser oscillator 30 is pushed, and the laser oscillator 30 rotates counterclockwise in FIG. Is irradiated in a direction inclined to the left in FIG. When the second stopper 37 is moved downward, the restoring force of the compression spring 38 rotates in the clockwise direction in FIG. 6 with the ball 34 as a fulcrum, and the laser beam L is irradiated in a direction tilted to the right. As shown in FIG. 8, in order to align the position of the laser beam L in the direction perpendicular to the reference position Y, the second stopper 37 is rotated and moved up and down, and when the laser beam L coincides with the reference position Y, the second stopper 37. Stop. Thus, the position of the laser beam L in the right angle direction is set. The amount of movement of the laser oscillator 30 when the second stopper 37 is rotated once is only the screw lead of the second stopper 37, and the laser oscillator 30 can be finely moved up and down. With the above setting, the laser beam L of the laser oscillator 30 indicates the cutting position of the cutting blade 10 when the cutting blade body 8 is swung downward.

切断材料６２を切断する場合は、図９に示すように、切断材料６２上面には切断位置を示す墨線６３が記されており、切断材料６２へ照射したレーザー光Ｌに墨線６３を一致させることで、切断刃物１０と墨線６３が一致したことになる。次に、切断刃物本体８のハンドル２６を握り、切断刃物本体８を下方に揺動させ、切断材料６２を切断する。切断したい位置（墨線６３）と切断される位置のずれは極力少ないほうが良く、切断刃物１０の切断位置とレーザー光Ｌは正しく一致していなければならない。 When cutting the cutting material 62, as shown in FIG. 9, a black line 63 indicating the cutting position is written on the upper surface of the cutting material 62, and the black line 63 matches the laser light L irradiated to the cutting material 62. Thus, the cutting blade 10 and the black line 63 coincide. Next, the handle 26 of the cutting blade body 8 is gripped, the cutting blade body 8 is swung downward, and the cutting material 62 is cut. It is better that the deviation between the position to be cut (black line 63) and the position to be cut is as small as possible, and the cutting position of the cutting blade 10 and the laser beam L must be correctly matched.

次に、レーザー発振器を揺動させるための第２の実施形態について図１０〜図１２を用いて説明する。図１０は図３のＢ−Ｂ線一部断面図、図１１は図１０のＥ−Ｅ線断面図、図１２は図１１のＦ−Ｆ線一部断面図である。 Next, a second embodiment for swinging the laser oscillator will be described with reference to FIGS. 10 is a partial cross-sectional view taken along line BB in FIG. 3, FIG. 11 is a cross-sectional view taken along line EE in FIG. 10, and FIG. 12 is a partial cross-sectional view taken along line FF in FIG.

支持部材４２の凹部４３内の左側面前端部に円弧凹部４３ａを形成し、レーザー発振器４０の左側面前端部に円弧凹部４３ａに対応する円弧凸部４０ａを形成している。レーザー発振器４０は円弧凸部４０ａを支点に凹部４３内で揺動自在となる。凹部４３の円弧凹部４３ａの後方に第１ストッパ４５をねじ嵌合させ、第１ストッパ４５の先端は、レーザー発振器４０の左側面後端部に当接させる。レーザー発振器４０の右側面と支持部材４２の凹部４３側面との間にレーザー発振器４０を第１ストッパ４５側へ押圧する圧縮バネ４６を保持している。支持部材４２の下面に第２ストッパ４７をねじ嵌合させ、第２ストッパ４７は円弧凹部４３ａ、円弧凸部４０ａの反対側（図１１の右端）で、かつほぼ中央（図１２参照）に位置し、第２ストッパ４７の先端はレーザー発振器４０の下面に当接している。レーザー発振器４０の上面と支持部材４２との間に、レーザー発振器４０を第２ストッパ４７側へ押圧する圧縮バネ４８を保持している。圧縮バネ４８は図１２に示すように第２ストッパ４７に対し、左右に１個ずつ位置させ、レーザー発振器４０のバランスを保っている。 An arc recess 43 a is formed at the front end of the left side surface in the recess 43 of the support member 42, and an arc projection 40 a corresponding to the arc recess 43 a is formed at the front end of the left side surface of the laser oscillator 40. The laser oscillator 40 can swing within the concave portion 43 with the circular arc convex portion 40a as a fulcrum. The first stopper 45 is screwed behind the circular arc recess 43 a of the recess 43, and the tip of the first stopper 45 is brought into contact with the rear end portion of the left side surface of the laser oscillator 40. A compression spring 46 that presses the laser oscillator 40 toward the first stopper 45 is held between the right side surface of the laser oscillator 40 and the side surface of the concave portion 43 of the support member 42. The second stopper 47 is screwed to the lower surface of the support member 42, and the second stopper 47 is located on the opposite side (right end in FIG. 11) of the arc concave portion 43a and the arc convex portion 40a and substantially in the center (see FIG. 12). The tip of the second stopper 47 is in contact with the lower surface of the laser oscillator 40. A compression spring 48 that presses the laser oscillator 40 toward the second stopper 47 is held between the upper surface of the laser oscillator 40 and the support member 42. As shown in FIG. 12, one compression spring 48 is positioned on the left and right sides of the second stopper 47 to maintain the balance of the laser oscillator 40.

図１０に示すようにレーザー光Ｌの水平方向の位置を基準位置Ｘに合わせるには、第１ストッパ４５を回転させ左右方向に移動させることにより、レーザー発振器４０は円弧凸部４０ａを支点に左右方向に揺動し、レーザー光Ｌが基準位置Ｘと一致したところで第１ストッパ４５を止める。 As shown in FIG. 10, in order to align the horizontal position of the laser beam L with the reference position X, the laser oscillator 40 moves left and right with the circular arc convex portion 40a as a fulcrum by rotating the first stopper 45 and moving it in the left-right direction. When the laser beam L coincides with the reference position X, the first stopper 45 is stopped.

レーザー光Ｌの直角方向の位置を図８の基準位置Ｙに合わせるには、第２ストッパ４７を回転させ上下に移動させることにより、レーザー発振器４０は円弧凸部４０ａを支点に上下に揺動し、レーザー光Ｌが基準位置Ｙと一致したところで第２ストッパ４７を止める。以下、第１の実施形態同様な方法で切断作業をすれば良い。 In order to match the position of the laser beam L in the direction perpendicular to the reference position Y in FIG. 8, the laser oscillator 40 swings up and down around the arc convex portion 40a by rotating the second stopper 47 and moving it up and down. When the laser beam L coincides with the reference position Y, the second stopper 47 is stopped. Hereinafter, the cutting operation may be performed by the same method as in the first embodiment.

さらに、レーザー発振器を揺動させるための第３の実施形態について図１３〜図１５を用いて説明する。図１３は図３のＢ−Ｂ線一部断面図、図１４は図１３のＧ−Ｇ線断面図、図１５は図１４のＨ−Ｈ線一部断面図である。 Further, a third embodiment for swinging the laser oscillator will be described with reference to FIGS. 13 is a partial cross-sectional view taken along line BB in FIG. 3, FIG. 14 is a cross-sectional view taken along line GG in FIG. 13, and FIG. 15 is a partial cross-sectional view taken along line H-H in FIG.

支持部材５２の凹部５３内の左側面前端部に鋭角凹部５３ａを形成し、レーザー発振器５０の左側面前端部に鋭角凹部５３ａに対応する鋭角凸部５０ａを形成している。レーザー発振器５０は鋭角凸部５０ａを支点に凹部５３内で揺動自在となる。凹部５３の円弧凹部５３ａの後方に第１ストッパ５５をねじ嵌合させ、第１ストッパ５５の先端は、レーザー発振器５０の左側面後端部に当接させる。レーザー発振器５０の右側面と支持部材５２の凹部５３側面との間にレーザー発振器５０を第１ストッパ５５側へ押圧する圧縮バネ５６を保持している。支持部材５２の下面に第２ストッパ５７をねじ嵌合させ、第２ストッパ５７は鋭角凹部５３ａ、鋭角凸部５０ａの反対側（図１４の右端）で、かつほぼ中央（図１５参照）に位置し、第２ストッパ５７の先端はレーザー発振器５０の下面に当接している。レーザー発振器５０の上面と支持部材５２との間にレーザー発振器５０を第２ストッパ５７側へ押圧する圧縮バネ５８を保持している。圧縮バネ５８は図１５に示すように第２ストッパ５７に対し、左右に１個ずつ位置させ、レーザー発振器５０のバランスを保っている。 An acute angle recess 53a is formed at the left side front end of the recess 53 of the support member 52, and an acute angle projection 50a corresponding to the acute angle recess 53a is formed at the left side front end of the laser oscillator 50. The laser oscillator 50 can swing within the concave portion 53 with the acute angle convex portion 50a as a fulcrum. The first stopper 55 is screwed behind the circular arc recess 53 a of the recess 53, and the front end of the first stopper 55 is brought into contact with the rear end portion of the left side surface of the laser oscillator 50. A compression spring 56 that presses the laser oscillator 50 toward the first stopper 55 is held between the right side surface of the laser oscillator 50 and the side surface of the concave portion 53 of the support member 52. The second stopper 57 is screwed to the lower surface of the support member 52, and the second stopper 57 is located on the opposite side (right end in FIG. 14) of the acute angle concave portion 53a and the acute angle convex portion 50a and substantially in the center (see FIG. 15). The tip of the second stopper 57 is in contact with the lower surface of the laser oscillator 50. A compression spring 58 that presses the laser oscillator 50 toward the second stopper 57 is held between the upper surface of the laser oscillator 50 and the support member 52. As shown in FIG. 15, the compression spring 58 is positioned one by one on the left and right sides with respect to the second stopper 57 to keep the balance of the laser oscillator 50.

図１３に示すようにレーザー光Ｌの水平方向の位置を基準位置Ｘに合わせるには、第１ストッパ５５を回転させ左右方向に移動させることにより、レーザー発振器５０は円弧凸部５０ａの前側先端を支点に左右方向に揺動し、レーザー光Ｌが基準位置Ｘと一致したところで第１ストッパ５５を止める。 In order to align the horizontal position of the laser beam L with the reference position X as shown in FIG. 13, the laser oscillator 50 causes the front end of the arc-shaped convex portion 50a to move by rotating the first stopper 55 and moving it in the left-right direction. The first stopper 55 is stopped when the laser beam L oscillates left and right around the fulcrum and the laser beam L coincides with the reference position X.

次に、レーザー光Ｌの直角方向の位置を図８の基準位置Ｙに合わせるには、第１の実施形態同様第２ストッパ５７を回転させ上下に移動させることにより、レーザー発振器５０は鋭角凸部５０ａ先端を支点に上下に揺動し、レーザー光Ｌが基準位置Ｙと一致したところで第２ストッパ５７を止める。以下、第１の実施形態同様な方法で切断作業をすれば良い。 Next, in order to align the position of the laser beam L in the direction perpendicular to the reference position Y in FIG. 8, the laser oscillator 50 has an acute convex portion by rotating and moving the second stopper 57 up and down as in the first embodiment. The second stopper 57 is stopped when the laser beam L coincides with the reference position Y by swinging up and down with the tip of 50a as a fulcrum. Hereinafter, the cutting operation may be performed by the same method as in the first embodiment.
