Description

本発明は、円筒型ソレノイドに関し、特に、固定子コア部と可動子コア部に各々段差を形成し、可動子と固定子が離れた位置において、より大きい電磁力による磁気吸引を行うための新規な改良に関する。   The present invention relates to a cylindrical solenoid, and more particularly to a novel solenoid for forming a step in a stator core portion and a mover core portion, and performing magnetic attraction by a larger electromagnetic force at a position where the mover and the stator are separated. About improvement.

従来、用いられていたこの種の円筒型ソレノイドとしては、例えば、図７に示す特許文献等に示されていない第１従来構成（すなわち、本出願人が社内で実験的に従来開発した画面上の構成）は挙げることができる。
すなわち、図７は、従来構成の軸対称断面図で示されており、励磁コイル１を内蔵した輪状の固定子２の固定子コア部１１の上面２ａには、第４段差５すなわち第１吸引面４が形成されている。
前記固定子２の上面２ａにおける前記励磁コイル１の側部２ｂ上には、第１吸引面４が形成されている。 Conventional cylindrical solenoids of this type include, for example, a first conventional configuration not shown in the patent document shown in FIG. Configuration) can be cited.
That is, FIG. 7 is an axially symmetric cross-sectional view of the conventional configuration, and the upper surface 2a of the stator core portion 11 of the annular stator 2 having the built-in excitation coil 1 has the fourth step 5, that is, the first suction. Surface 4 is formed.
A first suction surface 4 is formed on a side 2b of the exciting coil 1 on an upper surface 2a of the stator 2.

前記固定子２の上方には、可動子７が可動方向Ａに沿うと共に可動範囲Ｂに沿って上下動自在に構成されている。
すなわち、前記可動子７は、通常の励磁コイル１の非励磁時には、図示しない周知の弾性体又は他の装置によって、両方向矢印に沿う可動範囲Ｂが維持されるように構成されている。
また、前記固定子２の前記励磁コイル１の上方に位置する可動子７の一部は、可動子コア部１０として、側方に延設されてその下面に第３吸引面１２が形成されている。
尚、図７の前述の構成において、前記励磁コイル１を励磁すると、前記固定子２側から発生する磁気力により、前記可動子７は、磁性体であるため、矢印Ａの可動方向に向けて前記固定子２に磁気吸着される。
尚、この時の前記可動子７のストロークは、前記両方向を矢印で示される可動範囲Ｂで示している。
従って、前述の磁気吸着時には、前記可動子７の前記第３吸引面１２及び前記第４吸引面１４（第１段差３）は、第１吸引面４及び第２吸引面６（第２段差１５）に吸引し、従来の円筒型ソレノイドが矢印Ａに沿って往復動するように製作されていた。 Above the stator 2, a mover 7 is configured to be vertically movable along a movable direction A and along a movable range B.
That is, the movable element 7 is configured such that the movable range B along the double-headed arrow is maintained by a well-known elastic body or another device (not shown) when the ordinary exciting coil 1 is not excited.
Further, a part of the mover 7 located above the excitation coil 1 of the stator 2 is laterally extended as a mover core 10 and a third suction surface 12 is formed on the lower surface thereof. I have.
In the above-described configuration of FIG. 7, when the exciting coil 1 is excited, the movable element 7 is a magnetic substance due to the magnetic force generated from the stator 2 side. It is magnetically attracted to the stator 2.
Note that the stroke of the mover 7 at this time is indicated by a movable range B indicated by an arrow in both directions.
Therefore, at the time of the magnetic attraction described above, the third suction surface 12 and the fourth suction surface 14 (first step 3) of the mover 7 are connected to the first suction surface 4 and the second suction surface 6 (second step 15). ), And the conventional cylindrical solenoid is manufactured to reciprocate along arrow A.

次に、特許文献１で示される第２従来構成の場合、図示していないが、リニアソレノイド装置及び電磁弁を示している。   Next, in the case of the second conventional configuration shown in Patent Document 1, although not shown, a linear solenoid device and an electromagnetic valve are shown.

特開２００９−１２７６９２号公報JP-A-2009-127692

本発明は、以上のように構成されていたため、次のような課題が存在していた。
まず、図７で示される第１従来例の構成において、固定子のコイルに電流を流すことで、電磁力を発生させて、可動子を動かす場合、発生する電磁力の大きさは、固定子と可動子の吸引面の大きさと、２つの面の距離に依存するため、面間の距離が大きくなると、大きな推力を得ることが困難であった。
すなわち、図８に示されるように、可動子が０位置（固定子から最も離れている位置）では、可動子が固定子に最も近づいている点に比べ、非常に小さいことが分かる。
また、可動子と固定子の吸引面の距離は可動範囲に関係するため、面間の距離を縮めることで大きな電磁力を得ることは困難であった。すなわち、図９の磁束解析図及び図１０の磁束密度図の通りである。 Since the present invention is configured as described above, the following problems exist.
First, in the configuration of the first conventional example shown in FIG. 7, when a current is applied to the coil of the stator to generate an electromagnetic force and move the mover, the magnitude of the generated electromagnetic force depends on the stator. And the size of the suction surface of the mover, and the distance between the two surfaces, it was difficult to obtain a large thrust when the distance between the surfaces was large.
That is, as shown in FIG. 8, it can be seen that the position of the mover at the zero position (the position farthest from the stator) is much smaller than the point at which the mover is closest to the stator.
Further, since the distance between the movable element and the suction surface of the stator is related to the movable range, it has been difficult to obtain a large electromagnetic force by reducing the distance between the surfaces. That is, they are as shown in the magnetic flux analysis diagram of FIG. 9 and the magnetic flux density diagram of FIG.

また、前述の特許文献１を用いた第２従来例の場合、第１の固定子と可動子との間の磁気クリアランスを小さくすることができ、磁気効率をさらに向上することは可能であるが、磁気力をより一層強化することは困難であった。   In the case of the second conventional example using the above-mentioned Patent Document 1, the magnetic clearance between the first stator and the mover can be reduced, and the magnetic efficiency can be further improved. However, it has been difficult to further enhance the magnetic force.

本発明は、以上のような課題を解決するためになされたもので、特に、固定子コア部と可動子コア部に各々段差を形成することで、固定子と可動子が離れた位置において従来より大きい電磁力による磁気吸引を行うようにした円筒型ソレノイドを提供することを目的とする。   The present invention has been made in order to solve the above-described problems, and in particular, a step is formed in each of a stator core portion and a mover core portion so that the stator and the mover can be separated from each other at a distance. It is an object of the present invention to provide a cylindrical solenoid that performs magnetic attraction by a larger electromagnetic force.

本発明による円筒型ソレノイドは、励磁コイルを有する固定子から離れている可動子を、前記励磁コイルに電流を流すことで生じる電磁力で吸引することにより、直線移動させるようにし、前記可動子に形成された複数の第１段差と、前記固定子に形成された複数の第２段差と、を備え、前記第１段差は各第４吸引面を兼ねており、前記第２段差は第２吸引面を兼ねている構成よりなる円筒型ソレノイドにおいて、前記励磁コイルに電源が印加されると、前記可動子の前記各第４吸引面が、前記固定子の前記第２吸引面に磁気吸引される構成であり、また、前記可動子の上端に位置して設けられ、前記固定子の軸心に向かって延設された可動子コア部と、前記可動子コア部の下面に形成された第３吸引面と、前記固定子の固定子コア部と、前記固定子コア部の上面に形成された前記第１吸引面とを備え、前記励磁コイルに前記電源が印加されると、前記可動子コア部の第３吸引面は、前記固定子コア部の前記第１吸引面に磁気吸引されるようにした構成であり、また、前記可動子の各第４吸引面の角部と前記固定子の各第２吸引面の角部同志は、角点を形成する構成である。   The cylindrical solenoid according to the present invention is configured to linearly move a mover separated from a stator having an exciting coil by an electromagnetic force generated by flowing a current through the exciting coil, and to move the mover. A plurality of first steps formed and a plurality of second steps formed on the stator are provided, wherein the first steps also serve as fourth suction surfaces, and the second steps are second suction means. In a cylindrical solenoid having a configuration also serving as a surface, when power is applied to the excitation coil, the fourth suction surfaces of the mover are magnetically attracted to the second suction surface of the stator. A mover core provided at an upper end of the mover and extending toward an axis of the stator; a third mover formed on a lower surface of the mover core; A suction surface, a stator core portion of the stator, The first attracting surface formed on the upper surface of the stator core portion, and when the power is applied to the exciting coil, the third attracting surface of the mover core portion has the third attracting surface of the stator core portion. The first suction surface is magnetically attracted, and a corner of each fourth suction surface of the mover and a corner of each second suction surface of the stator form a corner point. It is a configuration to do.

本発明による円筒型ソレノイドは、以上のように構成されているため、次のような効果を得ることができる。
すなわち、図１のように、可動子が固定子から最も離れている位置で、固定子と可動子の角点がわずかな隙間をつくるように、固定子、可動子の吸引面に段差をつくることにより、固定子と可動子の吸引面が互いに垂直に引き合う磁気力だけではなく、固定子と可動子の角点７０（図４の磁束の流れ、及び、図２と図５に示す）に集中する磁束が、より多くの磁束を流そうとすることによる磁気吸引力が発生するため、固定子と可動子が最も離れた位置において、従来よりも大きい電磁力、すなわち、電磁吸着力を得ることができる。 Since the cylindrical solenoid according to the present invention is configured as described above, the following effects can be obtained.
That is, as shown in FIG. 1, at the position where the mover is farthest from the stator, a step is formed on the suction surface of the stator and the mover so that the corner points between the stator and the mover make a slight gap. As a result, not only the magnetic force at which the attracting surfaces of the stator and the mover attract each other perpendicularly, but also the corner point 70 of the stator and the mover (the flow of magnetic flux in FIG. 4 and shown in FIGS. 2 and 5). Since the concentrated magnetic flux generates a magnetic attraction force by trying to flow more magnetic flux, at a position where the stator and the mover are farthest apart, a larger electromagnetic force than before, that is, an electromagnetic attraction force is obtained. be able to.

尚、図６は、前述の固定子と可動子の磁気吸引力の関係を示しているが、前記固定子の各段差の形状を適切に選ぶことにより、この曲線の特性を制御することができる。
さらに、本実施の形態では、段差を実質２段設け、角点も２個所としているが、２個以上として特性を変えることもできる。 FIG. 6 shows the relationship between the magnetic attraction force of the stator and the mover described above. By appropriately selecting the shape of each step of the stator, the characteristics of this curve can be controlled. .
Furthermore, in the present embodiment, substantially two steps are provided and two corner points are provided, but the characteristics can be changed to two or more.

本発明による円筒型ソレノイドは、固定子コア部と可動子コア部に各々段差を形成し、可動子が固定子から最も離れている位置で、固定子と可動子の角点がわずかな隙間をつくるように、固定子、可動子の吸引面に段差をつくることにより、従来より大なる吸引力を得ることができる。   In the cylindrical solenoid according to the present invention, a step is formed in each of the stator core portion and the mover core portion, and at a position where the mover is farthest from the stator, the corner point between the stator and the mover has a slight gap. By forming a step on the suction surface of the stator and the mover, a larger suction force than in the related art can be obtained.

以下、図面と共に本発明による円筒型ソレノイドの好適な実施の形態について説明する。
尚、従来例と同一又は同等部分には、同一符号を付して説明する。
図１は本発明による円筒型ソレノイドの軸対称断面図であり、励磁コイル１を内蔵した輪状の固定子２の固定子コア部１１の上面２ａには、第４段差５（第１吸引面４）が設けられている。 Hereinafter, preferred embodiments of a cylindrical solenoid according to the present invention will be described with reference to the drawings.
Note that the same or equivalent parts as those in the conventional example are denoted by the same reference numerals and described.
FIG. 1 is an axially symmetric cross-sectional view of a cylindrical solenoid according to the present invention. The upper surface 2a of a stator core portion 11 of a ring-shaped stator 2 having a built-in excitation coil 1 has a fourth step 5 (first suction surface 4). ) Is provided.

前記固定子２の固定子コア部１１の外側には、上方より下方へ向けて、一対の第２段差１５（第２吸引面６）が連続して形成されている。
前記固定子コア部１１の上方及び側方には、可動子コア部１０を有する可動子７が矢印Ａの方向に沿って前記固定子２に引き付けられるように構成され、前記励磁コイル１への電流オフによって前記可動子７は図示しない周知の弾性体又は他の図示しない構成により、磁気吸引される前の位置に戻るように構成されている。 Outside the stator core portion 11 of the stator 2, a pair of second steps 15 (second suction surfaces 6) are formed continuously from above to below.
Above and to the side of the stator core 11, a mover 7 having a mover core 10 is configured to be attracted to the stator 2 along the direction of arrow A, and When the current is turned off, the movable element 7 is configured to return to a position before magnetic attraction by a well-known elastic body (not shown) or another configuration (not shown).

前記可動子７の上部の可動子コア部１０の下面には、第１吸引面４に対向して第２段差１３からなる第３吸引面１２が形成されている。
前記可動子７の側部下面５１には、前記固定子２の一対の第２段差１５（第２吸引面６）に対向して一対の第１段差（第４吸引面１４）が互いに吸引できるように、形成されている。 On the lower surface of the mover core 10 above the mover 7, a third suction surface 12 composed of a second step 13 is formed so as to face the first suction surface 4.
A pair of first steps (fourth suction surfaces 14) can be attracted to the pair of second steps 15 (second suction surfaces 6) on the side lower surface 51 of the mover 7 in opposition to the pair of second steps 15 (second suction surfaces 6) of the stator 2. So, it is formed.

図１において、符号Ｂで示されるものは、前記固定子２と前記可動子７及び前記可動子コア部１０間におけるギャップ（可動範囲）を示しており、前述のように、前記励磁コイル１が励磁された時に、前記可動子７が前記ギャップＢ分だけ下方へ移動して、前記固定子２に磁気吸引されて、図３のように互いに吸引された状態となる。   In FIG. 1, a reference numeral B indicates a gap (movable range) between the stator 2, the mover 7, and the mover core 10. As described above, the exciting coil 1 is When excited, the mover 7 moves downward by the gap B, is magnetically attracted to the stator 2 and is attracted to each other as shown in FIG.

図２は、図１で示される円筒型ソレノイド６０の励磁コイル１を励磁する前の状態において、図２、図４及び図５で示されるように、前記固定子２が可動子７を吸引する力は、前記固定子２と前記可動子７の距離と、前記固定子２と可動子７の吸引する面積に依存する。
本発明においては、前記固定子２と前記可動子７の吸引面が互いに垂直に引き合う力だけでなく、前記固定子２と前記可動子７の角点７０に集中する磁束が、より多くの磁束を流そうとすることによる吸引力が存在するため、前記固定子２と前記可動子７が最も離れた位置において、大きい電磁力を得ることができる（図４と図５に図示）。 FIG. 2 shows the state in which the stator 2 attracts the mover 7 in a state before the excitation coil 1 of the cylindrical solenoid 60 shown in FIG. 1 is excited, as shown in FIG. 2, FIG. 4 and FIG. The force depends on the distance between the stator 2 and the mover 7 and the area of suction between the stator 2 and the mover 7.
In the present invention, not only the force of attracting the attracting surfaces of the stator 2 and the mover 7 perpendicular to each other, but also the magnetic flux concentrated on the corner 70 of the stator 2 and the mover 7 increases the magnetic flux. As a result, there is an attractive force due to the flow of the electromagnetic force, so that a large electromagnetic force can be obtained at a position where the stator 2 and the mover 7 are farthest apart (shown in FIGS. 4 and 5).

すなわち、図６の特性図からも明らかなように、前記可動子７が０位置（前記固定子２から最も離れている位置）では、従来技術に比べてはるかに大きい電磁力が得られていることが明らかである。
図６では、電磁力が０位置に比べ減少している可動子７の位置も存在するが、前記固定子２と可動子７の段差３,５の形状を適切に選ぶことにより、この曲線も制御することが可能である。
また、本形態では、段差３,５は２段設けているが、２段以上の複数段においても有益な方法である。 That is, as is clear from the characteristic diagram of FIG. 6, when the mover 7 is at the 0 position (the position farthest from the stator 2), a much larger electromagnetic force is obtained as compared with the related art. It is clear that.
In FIG. 6, there is a position of the mover 7 where the electromagnetic force is reduced as compared with the position 0. However, by appropriately selecting the shapes of the steps 3 and 5 between the stator 2 and the mover 7, this curve is also reduced. It is possible to control.
Further, in the present embodiment, the steps 3, 5 are provided in two stages, but this is also a useful method in two or more stages.

尚、本発明による円筒型ソレノイドの要旨とするところは、以下の通りである。
励磁コイル１を有する固定子２から離れている可動子７を、前記励磁コイル１に電流を流すことで生じる電磁力で吸引することにより、直線移動させるようにし、前記可動子７に形成された複数の第１段差３と、前記固定子２に形成された複数の第２段差１５と、を備え、前記第１段差３は各第４吸引面１４を兼ねており、前記第２段差１５は第２吸引面６を兼ねている構成よりなる円筒型ソレノイドにおいて、前記励磁コイル１に電源が印加されると、前記可動子７の前記各第４吸引面１４が、前記固定子２の前記第２吸引面６に磁気吸引される構成であり、また、前記可動子７の上端５５に位置して設けられ、前記固定子２の軸心に向かって延設された可動子コア部１０と、前記可動子コア部１０の下面に形成された第３吸引面１２と、前記固定子２の固定子コア部１１と、前記固定子コア部１１の上面２ａに形成された第１吸引面４とを備え、前記励磁コイル１に前記電源が印加されると、前記可動子コア部１０の第３吸引面１２は、前記固定子コア部１１の前記第１吸引面４に磁気吸引されるようにした構成であり、また、前記可動子７の各第４吸引面１４の角部Ｍと前記固定子２の各第２吸引面６の角部同志は、角点７０を形成する構成である。 The gist of the cylindrical solenoid according to the present invention is as follows.
The movable element 7, which is separated from the stator 2 having the exciting coil 1, is linearly moved by being attracted by an electromagnetic force generated by applying a current to the exciting coil 1, so that the movable element 7 is formed on the movable element 7. A plurality of first steps 3 and a plurality of second steps 15 formed on the stator 2 are provided. The first steps 3 also serve as the fourth suction surfaces 14, and the second steps 15 In a cylindrical solenoid having a configuration also serving as the second suction surface 6, when power is applied to the exciting coil 1, each of the fourth suction surfaces 14 of the mover 7 becomes the fourth suction surface of the stator 2. (2) a movable element core 10 that is magnetically attracted to the attracting surface 6, is provided at an upper end 55 of the movable element 7, and extends toward the axis of the stator 2; A third suction surface 12 formed on a lower surface of the mover core 10; A stator core portion of the stator; a first suction surface formed on an upper surface of the stator core; The third suction surface 12 of the core portion 10 is configured to be magnetically attracted to the first suction surface 4 of the stator core portion 11. The corner M and the corner of each second suction surface 6 of the stator 2 are formed to form a corner point 70.

本発明による円筒型ソレノイドは、可動子が固定子から最も離れている位置で、固定子と可動子の角点がわずかな隙間をつくるように、固定子、可動子の吸引面に段差をつくることにより、固定子と可動子の角点に集中する磁束が、より多くの磁束を流そうとすることによる吸引力が発生するため、固定子と可動子が最も離れた位置において大きい電磁力を得ることができる。   The cylindrical solenoid according to the present invention forms a step on the suction surface of the stator and the mover so that the corner point between the stator and the mover creates a slight gap at the position where the mover is farthest from the stator. As a result, the magnetic flux concentrated at the corner point between the stator and the mover generates an attractive force due to an attempt to flow more magnetic flux, so that a large electromagnetic force is generated at a position where the stator and the mover are farthest apart.
