【０００６】[0006]
つぎに本考案の実施例を図面にしたがって説明する。 当該アクチュエータはピストンを内蔵したアクチュエータ本体と、前記ピスト ンに取り付けられた永久磁石と、前記アクチュエータ本体の外壁に取り付けられ た位置検出器と、を有し、前記ピストンが前記位置検出器に近付いたときに前記 位置検出器が磁力により前記ピストンの位置を検出するものであって、更に、次 の特徴を有している。 Next, an embodiment of the present invention will be described with reference to the drawings. The actuator has an actuator body with a built-in piston, a permanent magnet attached to the piston, and a position detector attached to the outer wall of the actuator body, and the piston comes close to the position detector. The position detector sometimes detects the position of the piston by magnetic force, and further has the following features.
【０００７】 図１ないし図６に示すように、略長方体形を呈するアクチュエータ本体１の外 壁に位置検出器取付溝２が形成され、該位置検出器取付溝２に位置検出器３が収 容されている。位置検出器３は位置検出器取付溝２に対してピストンの移動方向 と直交する方向（アクチュエータ本体１の外壁面と直交する方向）に出し入れ自 在である。当該アクチュエータはアクチュエータ本体１に開設した一対のポート ４からアクチュエータ本体１の内部へ流体圧（圧縮空気）を交互に供給して図示 しないピストンを直線的に往復動させ、該ピストンに一端を接続したロッド５を その軸方向に沿って直線的に往復動させるものであって、位置検出器取付溝２は このピストンの移動方向に沿ってアクチュエータ本体１の端から端まで形成され ている。また位置検出器取付溝２はアクチュエータ本体１の天面と底面に二本ず つ、都合四本（図１には三本が描かれ、四本目はロッド５の陰に隠れている）が 形成され、四本のうちの任意の二本の位置検出器取付溝２に位置検出器３が一個 ずつ収容されている。位置検出器取付溝２を余分に形成したのは当該アクチュエ ータの装着箇所次第で配線の都合が変わることから状況に応じて配線をできるだ け簡略にするためであり、位置検出器３を都合二個使用するのはピストンが往復 動の端限に来たことを両端限のそれぞれにおいて検出して流体圧の供給を停止さ せるためである。また各位置検出器取付溝２の側壁に一対の係合凹部６が位置検 出器取付溝２の全長に亙って互いに向かい合わせに形成されている。この係合凹 部６があることにより位置検出器取付溝２の断面形状は略十字形である（図６参 照）。As shown in FIGS. 1 to 6, a position detector mounting groove 2 is formed on an outer wall of an actuator body 1 having a substantially rectangular parallelepiped shape, and the position detector 3 is housed in the position detector mounting groove 2. Is included. The position detector 3 is self-moving in and out of the position detector mounting groove 2 in a direction orthogonal to the moving direction of the piston (direction orthogonal to the outer wall surface of the actuator body 1). The actuator alternately supplies fluid pressure (compressed air) into the actuator body 1 from a pair of ports 4 formed in the actuator body 1 to linearly reciprocate a piston (not shown) and connect one end to the piston. The rod 5 linearly reciprocates along its axial direction, and the position detector mounting groove 2 is formed from end to end of the actuator body 1 along the moving direction of the piston. Also, two position detector mounting grooves 2 are formed on the top and bottom of the actuator body 1, and four for convenience (three in FIG. 1 are drawn, the fourth is hidden behind the rod 5). The position detectors 3 are housed in the position detector mounting grooves 2 of any two of the four position detectors. The position detector mounting groove 2 is additionally formed in order to simplify wiring as much as possible depending on the situation because the convenience of wiring changes depending on the mounting location of the actuator. The reason why two pistons are used is that the supply of fluid pressure is stopped by detecting that the piston has reached the end of reciprocating motion at each end. A pair of engaging recesses 6 are formed on the side wall of each position detector mounting groove 2 so as to face each other over the entire length of the position detector mounting groove 2. Due to the presence of this engaging recess 6, the position detector mounting groove 2 has a substantially cross-shaped cross section (see FIG. 6).
【０００８】 位置検出器３は、図２に示すように、磁力による近接スイッチ機構を内蔵した 位置検出器本体７とその一端に接続された配線８とを有している。位置検出器本 体７の他端に凹段部９が形成され、該凹段部９に納まるように略平行四辺形のナ ット（以下、菱形ナットとも称する）１０が配置され、該菱形ナット１０のねじ 孔１１と同心となるように位置検出器本体７に位置決め孔１２が形成されている 。位置決め孔１２は非貫通であり、またこの位置決め孔１２の内周面にはねじ加 工は施されていない。符号１３は菱形ナット１０に螺合され、位置決め孔１２に 差し込まれる固定ねじである。菱形ナット１０はこれを位置検出器取付溝２に収 容して回転させたときのみ係合凹部６に侵入して該係合凹部６に係合し、抜け止 め作用を奏する。As shown in FIG. 2, the position detector 3 has a position detector main body 7 having a built-in proximity switch mechanism by magnetic force and a wiring 8 connected to one end thereof. A concave step portion 9 is formed at the other end of the position detector body 7, and a substantially parallelogram nut (hereinafter also referred to as a rhombic nut) 10 is arranged so as to be housed in the concave step portion 9, A positioning hole 12 is formed in the position detector main body 7 so as to be concentric with the screw hole 11 of the nut 10. The positioning hole 12 is non-penetrating, and the inner peripheral surface of the positioning hole 12 is not threaded. Reference numeral 13 is a fixing screw screwed into the diamond nut 10 and inserted into the positioning hole 12. The diamond-shaped nut 10 enters the engaging concave portion 6 and engages with the engaging concave portion 6 only when it is accommodated in the position detector mounting groove 2 and rotated, and has a retaining function.
【０００９】 つぎに上記構成による位置検出器３の固定方法を説明する。 すなわち、アクチュエータ本体１の任意の位置検出器取付溝２の所望の位置に 位置検出器３と菱形ナット１０を重ねて収容し、菱形ナット１０を回転させて該 菱形ナット１０を一対の係合凹部６に係合させ、ドライバー等の治具を使って該 菱形ナット１０に固定ねじ１３をねじ込む。菱形ナット１０にねじ込まれた固定 ねじ１３はねじ込みが深くなると位置決め孔１２の底部に当接する。ねじ込みを 更に続けると菱形ナット１０が相対に浮き上がり、該菱形ナット１０が一対の係 合凹部６の内面（図６における上面）に圧接して位置検出器３がアクチュエータ 本体１に固定される。Next, a method of fixing the position detector 3 having the above configuration will be described. That is, the position detector 3 and the diamond-shaped nut 10 are housed in an overlapping manner at a desired position in the arbitrary position-detector mounting groove 2 of the actuator body 1, and the diamond-shaped nut 10 is rotated to allow the diamond-shaped nut 10 to form a pair of engaging recesses. 6 and the fixing screw 13 is screwed into the diamond-shaped nut 10 using a jig such as a screwdriver. The fixing screw 13 screwed into the diamond-shaped nut 10 comes into contact with the bottom of the positioning hole 12 when the screwing becomes deep. When the screwing is further continued, the diamond-shaped nut 10 floats up relative to each other, the diamond-shaped nut 10 is pressed against the inner surfaces (upper surface in FIG. 6) of the pair of engaging recesses 6, and the position detector 3 is fixed to the actuator body 1.
【００１０】 上記構成において、位置検出器３は位置検出器取付溝２の内部に収容されてい る。よって位置検出器３がアクチュエータ本体１から突出して邪魔になることが なく、見た目にもすっきりとした印象を与えることができる。また位置検出器取 付溝２に対する位置検出器３の出し入れをピストンの移動方向と直交する方向に 行なうことができるために、位置検出器３を位置検出器取付溝２に沿ってスライ ドさせる必要がなく、よって着脱の作業が簡単である。In the above structure, the position detector 3 is housed inside the position detector mounting groove 2. Therefore, the position detector 3 does not protrude from the actuator main body 1 and becomes an obstacle, and a neat impression can be given to the appearance. Further, since the position detector 3 can be inserted into and removed from the position detector mounting groove 2 in a direction orthogonal to the moving direction of the piston, it is necessary to slide the position detector 3 along the position detector mounting groove 2. Therefore, the work of putting on and taking off is easy.
