Description

本発明は、電磁力によって可動板を駆動するロングストロークソレノイドに関する。   The present invention relates to a long stroke solenoid that drives a movable plate by electromagnetic force.

従来のソレノイドは磁気吸引力を用いるため、ロングストローク化のためには複数のコイル構造を用いていたが、特許文献1に記載されているように、各段の空隙を等しくするために、構造が複雑でトラブルが多かった。   Since the conventional solenoid uses a magnetic attractive force, a plurality of coil structures have been used to achieve a long stroke. However, as described in Patent Document 1, a structure is used in order to equalize the gaps at each stage. There were many troubles.

従来のロングストロークソレノイドは、構造が複雑で製造コストが大きく、動作初期時の推力が非常に弱い、ということがあった。   Conventional long stroke solenoids have a complicated structure, a high manufacturing cost, and a very low thrust at the initial stage of operation.

I kept the distance.


コイルの内側に非磁性体のケースを取付け、コイルの外周に強磁性体のケースを取付けた。   A non-magnetic case was attached to the inside of the coil, and a ferromagnetic case was attached to the outer periphery of the coil.

本発明は、以上の構成であるから以下の効果が得られる。第1に導線を巻いたコイルの両端に、可動板を連設したロッドを保持したシンプルな構造としたため、故障が少ない。   Since this invention is the above structure, the following effects are acquired.

以下に、本発明に係るロングソレノイド10を、図1を参照して説明する。
図1に示すようにロングソレノイド10は、導線を矩形状もしくは楕円状に巻いたコイル11内部を長手方向に摺動可能に設置された非磁性体のロッド12に、前記ロッド12に固着された強磁性体の板14と、摺動可能な1枚および複数の強磁性体の可動板13を連設し、連設した前記強磁性体の可動板13をバネ15で保持したものにおいて、コイル11に電流を流すと摺動可能な前記強磁性体の可動板13が反発して距離を保つようにした。
Below, the long solenoid 10 which concerns on this invention is demonstrated with reference to FIG.
As shown in FIG. 1, a long solenoid 10 is fixed to a rod 12 made of a non-magnetic material that is slidable in a longitudinal direction inside a coil 11 in which a conducting wire is wound in a rectangular or elliptical shape. A ferromagnetic plate 14, one slidable movable plate and a plurality of ferromagnetic movable plates 13 are connected in series, and the connected ferromagnetic movable plate 13 is held by a spring 15. The movable plate 13 made of a slidable ferromagnetic material is repelled when an electric current is passed through it to keep the distance.

図2に電流を流す前後の形態を示す。図2(a)で通電する前は可動板13と固定版14はバネ15に押付けられて、コイル11の中で反移動方向に押付けられた状態にある。次に図2(b)で、ここでコイル11に通電すると可動板13同士、及び可動板13と固定板14が反発し、バネ15を抑える方向に力が働き、固定板14は移動方向に押付けられることになる。これと同時にロッド12は前進することになる。   FIG. 2 shows a form before and after flowing current. Before energization in FIG. 2A, the movable plate 13 and the fixed plate 14 are pressed against the spring 15 and are pressed in the anti-movement direction in the coil 11. Next, in FIG. 2B, when the coil 11 is energized here, the movable plates 13 and the movable plate 13 and the fixed plate 14 repel each other, and a force acts in a direction to suppress the spring 15, and the fixed plate 14 moves in the moving direction. It will be pushed. At the same time, the rod 12 moves forward.

図3に示すようにロングソレノイド20は、導線を矩形状もしくは楕円状巻いたコイル11の両端部に保持された、強磁性体の可動板13を固着させた非磁性のロッド12に摺動可能な1枚および数枚の強磁性体の可動板13を連設し、連設した前記強磁性体の可動板13をバネ15で保持したものにおいて、コイル11に電流を流すと摺動可能な前記強磁性体の可動板13同士、及び可動板13と固定板14が反発して距離を保つようにした。
導線巻いたコイル11の内側には非磁性体のケース22、外側には強磁性体のケース21とによってコイル11は保持されている。
As shown in FIG. 3, the long solenoid 20 is slidable on a non-magnetic rod 12 which is held at both ends of a coil 11 in which a conducting wire is wound in a rectangular or elliptical shape and which has a ferromagnetic movable plate 13 fixed thereto. A single and several ferromagnetic movable plates 13 are connected in series, and the ferromagnetic movable plates 13 held by springs 15 are slidable when a current is passed through the coil 11. The movable plates 13 of the ferromagnetic material and the movable plate 13 and the fixed plate 14 are repelled to keep a distance.
The coil 11 is held by a non-magnetic case 22 on the inside of the coil 11 wound with a conductive wire and a ferromagnetic case 21 on the outside.

図4にコイル11に電流が流れた時、コイル11には右ネジの法則により上向きの磁力線が発生する。さらにこの磁力線により可動板13及び固定板14には下側がN極で上側がS極の磁場が発生する。それぞれの可動板13と固定板14に同じような磁場が発生するので、それらはお互いに反発し、ある距離を保つことになる。この距離は磁場の強さ、即ち電流値が大きくなると距離が大きくなり、また可動板13及び固定板14の厚みが厚くなるほど距離は大きくなる。
また、コイル11に流す電流の向きを逆にすると、前記磁力線の向きは下向きに発生することになる。
In FIG. 4, when a current flows through the coil 11, upward magnetic lines of force are generated in the coil 11 according to the right-handed screw law. Furthermore, the magnetic field lines generate a magnetic field having a lower N pole and an upper S pole on the movable plate 13 and the fixed plate 14. Since the same magnetic field is generated in each movable plate 13 and fixed plate 14, they repel each other and keep a certain distance. The distance increases as the strength of the magnetic field, that is, the current value increases, and the distance increases as the thickness of the movable plate 13 and the fixed plate 14 increases.
Further, when the direction of the current flowing through the coil 11 is reversed, the direction of the magnetic field lines is generated downward.

本発明のコイル11に流す電流は直流である。   The current flowing through the coil 11 of the present invention is a direct current.

次に可動板13及び固定板14の特性について述べる。可動板13及び固定板14は強磁性体で、例えば鉄系材料などである。可動板13及び固定板14は矩形が望ましいが円形でもよい。可動板13及び固定板14の厚みが厚いほど大きな推力が発生する。可動板13及び固定板14は同じ厚みであることが望ましいが、板厚の違うものが混在してもよい。可動板13の枚数が多い方がストロークが長くなる。   Next, the characteristics of the movable plate 13 and the fixed plate 14 will be described. The movable plate 13 and the fixed plate 14 are ferromagnetic materials, for example, iron-based materials. The movable plate 13 and the fixed plate 14 are preferably rectangular, but may be circular. As the thickness of the movable plate 13 and the fixed plate 14 increases, a larger thrust is generated. Although it is desirable that the movable plate 13 and the fixed plate 14 have the same thickness, those having different plate thicknesses may be mixed. The larger the number of movable plates 13, the longer the stroke.

可動板13及び固定板14の厚みが薄く設定した時(例えば1mm)は可動板13の摺動部にガタが発生しないように図示しないブッシュを固定して、ガタの発生を防止する。   When the thickness of the movable plate 13 and the fixed plate 14 is set to be thin (for example, 1 mm), a bush (not shown) is fixed so that the sliding portion of the movable plate 13 does not generate backlash, thereby preventing backlash.

ロッド12は非磁性体でSUS、銅、真鍮、アルミ合金、プラスチック、セラミック、木材、コンクリートのようなものでもよい。   The rod 12 is a non-magnetic material such as SUS, copper, brass, aluminum alloy, plastic, ceramic, wood, concrete.

本発明は、以上の構成であるから以下の効果が得られる。第1に導線を巻いたコイルの両端に、可動板を連設したロッドを保持したシンプルな構造としたため、故障が少ない。
第2に連設した可動板を何枚にでもできるので、ロッドのストロークの長さを自由に選択することができる。
第3に装置を小型化でき、かつ大型化もできる。
Since this invention is the above structure, the following effects are acquired. First, since a simple structure in which a rod provided with a movable plate is held at both ends of a coil wound with a conducting wire, there are few failures.
Secondly, since any number of movable plates can be provided continuously, the stroke length of the rod can be freely selected.
Thirdly, the apparatus can be reduced in size and increased in size.
