Description

本考案は、特にステッピングモータにより偏心輪を駆動して角度を調整し、レーザー光により平面の基準を測定するレーザー水平器に関するものである。 The present invention particularly relates to a laser leveler that adjusts an angle by driving an eccentric wheel by a stepping motor and measures a reference of a plane by laser light.

従来の墨出しは、建築工事または家具製作ための基準となる点や、水平ライン、縦ラインなどを測定する場合に、人工的に墨出し線を引き、或いは、気泡管水準器を用いて移動させながら基準ラインを測定するが、測定した後、その墨出し線を消す手間が必要であることから、非常に不便である。その欠点を解決するために、現在技術により、簡単操作のレーザー水平器を有し、レーザー光を所望の角度に調整してスイッチをオンに切り替えると、レーザー光を物に投射して簡単に使える。 Conventional ink marking is artificially drawn or moved using a bubble tube level when measuring points that are the basis for building work or furniture production, horizontal lines, vertical lines, etc. While measuring the reference line, it is very inconvenient because it takes time to erase the marking line after measurement. In order to solve the drawbacks, the current technology has a laser level that is easy to operate. When the laser beam is adjusted to the desired angle and the switch is turned on, the laser beam is projected onto an object for easy use. .

既存のレーザー水平器は、さまざまな角度を有する床面上に静置するために、レーザー水平器の座台の下部に複数の支持部材が設けられ、それら支持部材を伸縮させることにより、レーザー水平器の座台を調整して安定的に静置させる。 In order to place the existing laser level on a floor surface having various angles, a plurality of support members are provided at the lower part of the laser level table, and by extending and contracting these support members, Adjust the pedestal of the vessel and leave it stationary.

前述各支持部材は、螺旋手段により一側方向に沿って移動するが、その螺旋手段のピッチが所定の距離を有することから、調整する時に、振動や温度による熱膨張・冷収縮により、レーザー光の精度に誤差が発生し、さらに、支持部材を調整する時にも誤差が発生することがあることから、レーザー光を遠距離に投射すると、測定の精度が大幅に下がり、また、その複数の支持部材を調整する時にも、一つずつ調整しなければならないので、時間が無駄になる上、誤差で出るおそれもあった。 Each of the support members moves along one side by the spiral means. Since the pitch of the spiral means has a predetermined distance, the laser beam is generated by thermal expansion / cold shrinkage due to vibration or temperature when adjusting. Errors may occur when adjusting the support member, and when the laser beam is projected over a long distance, the accuracy of the measurement is greatly reduced, and the multiple supports When adjusting the members, the adjustments must be made one by one, which wastes time and may cause errors.

ステッピングモータが偏心輪を駆動して設置角度の微調整を行なうことにより、既存のレーザー水平器における、支持部材の調整時に、誤差が発生するという問題や、微調整ができないという欠点を解決するレーザー水平器を提供する。 A laser that solves the problem that errors occur during adjustment of the support member in the existing laser leveler, and the disadvantage that fine adjustment is not possible, by the stepping motor driving the eccentric wheel to finely adjust the installation angle. Provide a level.

Measurement can be performed by projecting laser light after adjusting the light emitting module 60 to a desired angle. Further, since the elastic member provides a biasing force for contraction, the upper and lower bases 40 and 10 are pulled to bring the first eccentric ring 24 and the third eccentric ring 25 into firm contact with the corresponding portions, respectively. In addition, after the upper base 40 is adjusted, the lower base 10 can be restored.

The first eccentric wheel 24A is attached to the first output shaft of the first stepping motor 21A, and the first eccentric wheel 24A is in contact with the bottom surface 41A of the upper base 40A. On the other hand, the second drive member 30A is installed on the lower base 10A via the second base 36A, and has a second stepping motor 31A, and a second output shaft of the second stepping motor 31A has a second output shaft. An eccentric ring 34A is attached, and the second eccentric ring 34 is brought into contact with the bottom surface 41A of the upper base 40A, and is different from the laser leveler 1 in this point. Further, in the present embodiment, the laser light emitting module 60A is installed on the upper surface 42A of the upper base 40A, and the laser leveler 1A is disposed through the bottom surface 11A.

図９及び図１０に示すように、更に他の実施例におけるレーザー水平器１Ｂの構造は、その殆どがレーザー水平器１と同一であり、第一駆動部２０Ｂ及び第二駆動部材３０Ｂがそれぞれ、下座台１０Ｂの中心近傍、即ち、周縁近傍から貫通孔１３Ｂに接近した箇所に設置され、また、該第一駆動部２０Ｂの軸線と第二駆動部材３０Ｂの軸線との間に、３０度から１８０度までの範囲の角度θ２が設けられる。 As shown in FIGS. 9 and 10, the structure of the laser level 1B in still another embodiment is almost the same as that of the laser level 1, and the first driving unit 20B and the second driving member 30B are respectively It is installed in the vicinity of the center of the lower base 10B, that is, in the vicinity of the periphery from the vicinity of the through-hole 13B, and between 30 degrees between the axis of the first drive unit 20B and the axis of the second drive member 30B. An angle θ2 in the range up to 180 degrees is provided.

この実施例におけるレーザー水平器１Ｂを使用する時は、第一ステッピングモータ２１Ｂを駆動して第一偏心輪２４Ｂを回転させて第一プレート２３Ｂを移動させると共に、第三ステッピングモータ２２Ｂを駆動して第三偏心輪２５Ｂを回転させ、更に、第二ステッピングモータ３１Ｂを駆動して第二偏心輪３４Ｂを回転させて第二プレート３３Ｂ及び第四ステッピングモータ３２Ｂの第四偏心輪３５Ｂを移動させることによって、上座台４０Ｂを下座台１０Ｂに対して傾動させる。 When using the laser level 1B in this embodiment, the first stepping motor 21B is driven to rotate the first eccentric ring 24B to move the first plate 23B, and the third stepping motor 22B is driven. By rotating the third eccentric wheel 25B, and further driving the second stepping motor 31B to rotate the second eccentric wheel 34B to move the second eccentric wheel 35B of the second plate 33B and the fourth stepping motor 32B. The upper base 40B is tilted with respect to the lower base 10B.

本実施例は、下座台１０Ｂと上座台４０Ｂとの間に設置されるボールジョイント１５Ｂを支点とすることから、てこの原理によって、第一駆動部２０Ｂ及び第二駆動部材３０Ｂが支点と接近すれば接近する程、上座台４０Ｂが下座台１０Ｂに対して傾動できる角度が大きくなり、使用者がレーザー水平器１Ｂを調整する時に、その傾動角度を広く調整することができる。 In this embodiment, since the ball joint 15B installed between the lower seat base 10B and the upper base 40B is used as a fulcrum, the first drive unit 20B and the second drive member 30B approach the fulcrum according to the lever principle. Thus, the closer it is, the larger the angle at which the upper seat 40B can tilt with respect to the lower seat 10B, and when the user adjusts the laser level 1B, the tilt angle can be adjusted widely.

本考案に係るレーザー水平器は上記の構成を有することから、第一駆動部材の少なくとも1つの第一偏心輪及び第二駆動部材の少なくとも1つの第二偏心輪の回転により、レーザー水平器の上座台を接触して移動させると共に、上座台を下座台に対して様々な角度に自由に傾動させることができることから、レーザー水平器からのレーザービームを微調整して測定精度を上向することができ、また、各駆動部材がステッピングモータを用いて偏心輪を回転させると共に、それら偏心輪の回転により上座台を移動させてレーザー発光モジュールを高精度に調整することができるので、操作が極めて簡単である。 Since the laser leveler according to the present invention has the above-described configuration, the top of the laser leveler is rotated by the rotation of at least one first eccentric ring of the first drive member and at least one second eccentric ring of the second drive member. The table can be moved in contact with it, and the upper table can be freely tilted to various angles with respect to the lower table, so that the measurement accuracy can be improved by fine-tuning the laser beam from the laser level. In addition, each drive member can rotate the eccentric wheel using a stepping motor, and the upper base can be moved by the rotation of the eccentric wheel so that the laser light emitting module can be adjusted with high accuracy.
