Description

本発明は、取付装置に関し、特に、シリンダーの横溝などの凹部に対して部品を取り付ける取付装置に関する。 The present invention relates to a mounting device, and more particularly to a mounting device for mounting a component in a recess such as a lateral groove of a cylinder.

特許文献1には、図6を用いた説明として、位置検出装置を、エアシリンダー本体の側面に形成されている溝に差し込み、つづいて、位置検出装置に設けられているネジ通し部に留めネジを合わせ、ドライバを用いて留めネジで留めること、及び、これにより、留めネジの先端が、溝の開口部分に対向する底部に当たり、位置検出装置本体が、溝の開口部分に隣接する内壁に押圧され、エアシリンダー本体に取り付けられることが開示されている。 In Patent Document 1, as an explanation using FIG. 6, a position detecting device is inserted into a groove formed on a side surface of an air cylinder body, and subsequently, a set screw is inserted into a screw threading portion provided in the position detecting device. And fasten with a set screw using a screwdriver, so that the tip of the set screw hits the bottom facing the opening of the groove and the position detector body presses against the inner wall adjacent to the opening of the groove. It is disclosed that it is attached to the air cylinder body.

しかし、特許文献1に開示されている取付手法では、シリンダーの横溝の底面に対してネジの先端が食い込むことになり、その底面にはネジの先端に対応する小径穴が形成されてしまう場合がある。 However, in the mounting method disclosed in Patent Document 1, the tip of the screw bites into the bottom surface of the lateral groove of the cylinder, and a small diameter hole corresponding to the tip of the screw may be formed on the bottom surface. be.

ここで、シリンダーに対するセンサの取り付けは、0.05mm〜0.10mmレベルの精度が求められることもあるため、シリンダーの使用に先立って、シリンダーに対するセンサの位置調整を綿密に行う必要が生じうる。 Here, since the mounting of the sensor on the cylinder may require an accuracy of 0.05 mm to 0.10 mm level, it may be necessary to carefully adjust the position of the sensor with respect to the cylinder prior to the use of the cylinder.

この位置調整は、通常、取付装置のネジを緩めた状態で、シリンダーの横溝内で、センサを所望の位置に付近に移動させてから、実際に、シリンダーを作動させ、所望の位置に到達したことを確認したら、ネジを締めることによって行う。ただし、上記のレベルの精度が求められる場合には、一度締めたネジを緩めて、シリンダーの横溝内で、センサを位置に所望の位置に移動させて、再度、ネジを締めることが必要となることがある。 This position adjustment usually involves moving the sensor closer to the desired position within the lateral groove of the cylinder, with the mounting device unscrewed, and then actually operating the cylinder to reach the desired position. After confirming that, do it by tightening the screws. However, if the above level of accuracy is required, it is necessary to loosen the screw once tightened, move the sensor to the desired position in the lateral groove of the cylinder, and tighten the screw again. Sometimes.

ところが、再度、ネジを締める際に、既に形成されてしまった小径穴にネジの先端が誘導されて、うまく、位置合わせを行うことができない場合がある。また、シリンダーの使用中には、シリンダー自体がその作動によって振動したり、その接続対象の装置の作動によって生じる振動が伝わって振動したりする。この結果、取付装置のネジが僅かに緩むと、すでに形成されている小径穴にネジの先端が誘導されるように、取付装置が位置ずれてしまうことがある。 However, when the screw is tightened again, the tip of the screw may be guided to the small diameter hole that has already been formed, and the alignment may not be performed properly. Further, during use of the cylinder, the cylinder itself vibrates due to its operation, or the vibration generated by the operation of the device to be connected is transmitted and vibrates. As a result, if the screw of the mounting device is slightly loosened, the mounting device may be misaligned so that the tip of the screw is guided to the already formed small diameter hole.

これを防止するためには、最終的なセンサの取付位置でのみネジを強く締め、多少の振動が生じたくらいでは、センサが位置ずれしないようにすることも考えられる。しかし、センサを何らかの理由により交換することになれば、結局、同じ問題が生じてしまうことになる。また、センサを交換せずとも、取付対象を交換することもあり、取付対象は、数μmを超える個体差があることも少なくないので、この場合にも同様の問題が生じうる。 In order to prevent this, it is conceivable to tighten the screws only at the final mounting position of the sensor so that the sensor does not shift even if some vibration occurs. However, if the sensor is replaced for some reason, the same problem will eventually occur. Further, even if the sensor is not replaced, the mounting target may be replaced, and the mounting target often has individual differences exceeding several μm. Therefore, the same problem may occur in this case as well.

そこで、本発明は、シリンダーの横溝など凹部に対するセンサなどの部品を取り付ける際に、凹部の底面に傷が生じる事態を回避することを課題とする。 Therefore, it is an object of the present invention to avoid a situation in which the bottom surface of the recess is scratched when a component such as a sensor is attached to the recess such as the lateral groove of the cylinder.

上記課題を解決するために、本発明の取付装置は、
凹部に対する取付対象を受ける取付対象受け部と、前記取付対象受け部に隣接して設けられているネジ受け部と、前記ネジ受け部に螺合されるネジ部及び円錐状の座面部を有するネジと、を備える取付装置であって、
前記ネジ受け部は、前記座面部に対向する位置に、前記ネジを螺合することで開状態となって、前記凹部の側面に押圧される面状部を有する複数の片部を備える。
In order to solve the above problems, the mounting device of the present invention
A screw having a mounting target receiving portion for receiving a mounting target for a recess, a screw receiving portion provided adjacent to the mounting target receiving portion, a screw portion screwed into the screw receiving portion, and a conical seat surface portion. It is a mounting device equipped with
The screw receiving portion includes a plurality of single portions having a planar portion that is opened by screwing the screw at a position facing the seat surface portion and is pressed against the side surface of the recess.

すなわち、本発明は、ネジを締めることによって、ネジの先端が凹部の底面に食い込む態様で取り付けるのではなく、各片部の面状部が開状態となって凹部の側面に押圧させることで取り付けている。そして、各変部は面状部を有しているため、従来のような点接触による取り付けではなく、面接触によって取り付けられる。この結果、ネジの先端によって形成される小径穴のようなものは形成されず、したがって、シリンダーに振動が発生しても、取付装置が位置ずれすることが回避できる。 That is, in the present invention, the screw is not attached in such a manner that the tip of the screw bites into the bottom surface of the recess by tightening the screw, but the planar portion of each piece is opened and pressed against the side surface of the recess. ing. Since each variable portion has a planar portion, it is attached by surface contact instead of the conventional point contact attachment. As a result, something like a small diameter hole formed by the tip of the screw is not formed, and therefore, even if vibration occurs in the cylinder, it is possible to prevent the mounting device from being displaced.

また、前記各片部は、前記座面部に対応する形状の円錐状部を有することができる。 In addition, each piece may have a conical portion having a shape corresponding to the seating surface portion.

さらに、前記各面状部は、曲面状とすることができる。 Further, each of the planar portions can be curved.

さらにまた、軸心に対する座面部の角度を、軸心に対する円錐状部の角度よりも、小さくすることができる。 Furthermore, the angle of the seating surface with respect to the axis can be made smaller than the angle of the conical portion with respect to the axis.

以下、本発明の実施形態について、図面を参照して説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図1は、本発明の実施形態の取付装置100の模式的な斜視図である。図1には、以下
説明する、取付対象受け部10と、ネジ受け部20と、ネジ30と、LED40と、ケーブル出口50とを示している。
FIG. 1 is a schematic perspective view of the mounting device 100 according to the embodiment of the present invention. FIG. 1 shows a mounting target receiving portion 10, a screw receiving portion 20, a screw 30, an LED 40, and a cable outlet 50, which will be described below.

なお、図1に示す取付装置100は、断面が角状の凹部に対する取付装置100であり、そのため、概形が直方体である。したがって、断面が丸状の凹部に対する取付装置100は、概形を円筒状とすることができる。 The mounting device 100 shown in FIG. 1 is a mounting device 100 for a concave portion having a rectangular cross section, and therefore has a rectangular parallelepiped shape. Therefore, the mounting device 100 for the recess having a round cross section can have a cylindrical shape.

取付対象受け部10は、シリンダーの横溝などの凹部に対して取り付けるセンサなどの取付対象を受けるものである。取付対象受け部10は、例えば、図面の斜め下方後方が開口されており、そこに取付対象を挿入し、適宜、接着剤等で固定すればよい。取付対象受け部10は、これに限定されるものではないが、樹脂製とすることができる。 The mounting target receiving portion 10 receives a mounting target such as a sensor to be mounted in a recess such as a lateral groove of a cylinder. The mounting target receiving portion 10 has, for example, an opening diagonally downward and rearward in the drawing, and the mounting target may be inserted therein and fixed with an adhesive or the like as appropriate. The mounting target receiving portion 10 is not limited to this, but may be made of resin.

ネジ受け部20は、取付対象受け部10に隣接して設けられていて、ネジ30が螺合される部分である。ネジ受け部20の具体的構成については、図2,図3を用いて後述するが、取付対象受け部10が樹脂製である場合には、金属製、アルミニウム製などとして、取付対象受け部10の隣接位置を開口して、そこに圧入などによって接続するとよい。 The screw receiving portion 20 is provided adjacent to the mounting target receiving portion 10, and is a portion into which the screw 30 is screwed. The specific configuration of the screw receiving portion 20 will be described later with reference to FIGS. 2 and 3, but when the mounting target receiving portion 10 is made of resin, the mounting target receiving portion 10 is made of metal, aluminum, or the like. It is advisable to open the adjacent position of and connect to it by press fitting or the like.

ネジ30は、ネジ受け部20に螺合されるものである。ネジ30をネジ受け部20に螺合することで、凹部に対して取付装置100を固定することができる。ネジ30の具体的構成についても、図2,図3を用いて後述する。 The screw 30 is screwed into the screw receiving portion 20. By screwing the screw 30 into the screw receiving portion 20, the mounting device 100 can be fixed to the recess. The specific configuration of the screw 30 will also be described later with reference to FIGS. 2 and 3.

LED40は、凹部がシリンダーの横溝であり、かつ、取付対象がシリンダー内のピストンのストロークを決定するための位置決めセンサである場合に、ピストンがストロークの端部に到達したこと、つまり、センサにおいてピストンの到来を検知した場合に点灯又は点滅させることができる。なお、LED40は、必ずしも設けなくてもよい点には留意されたい。 In LED40, when the recess is the lateral groove of the cylinder and the mounting target is a positioning sensor for determining the stroke of the piston in the cylinder, the piston reaches the end of the stroke, that is, the piston in the sensor. Can be turned on or blinked when the arrival of is detected. It should be noted that the LED 40 does not necessarily have to be provided.

ケーブル出口50は、取付対象受け部10に挿入されるセンサなどの取付対象がケーブルを有する場合には、そのケーブルを取り出すために形成されたものである。したがって、取付対象がケーブルを有しない場合には、必ずしもケーブル出口50を設けなくてもよいということになる。 The cable outlet 50 is formed to take out the cable when the attachment target such as the sensor inserted into the attachment target receiving portion 10 has a cable. Therefore, when the attachment target does not have a cable, it is not always necessary to provide the cable outlet 50.

図2は、図1に示す取付装置100を構成するネジ受け部20とネジ30との結合状態を示す斜視図である。図3は、図2に示すネジ受け部20及びネジ30の分解斜視図である。図2及び図3には、以下説明する、ネジ切り部22と、片部24,26と、頭部32と、工具穴34と、座面部36と、ネジ部38とを示している。 FIG. 2 is a perspective view showing a coupling state of the screw receiving portion 20 and the screw 30 constituting the mounting device 100 shown in FIG. FIG. 3 is an exploded perspective view of the screw receiving portion 20 and the screw 30 shown in FIG. 2 and 3 show a threaded portion 22, a piece portion 24, 26, a head portion 32, a tool hole 34, a seat surface portion 36, and a threaded portion 38, which will be described below.

ネジ切り部22は、円筒状をしており、その内壁にはネジ部38と螺合するために雌ネジが形成されている。また、その外壁は、取付対象受け部10の隣接位置の開口に圧入などによって接続できるようにしている。なお、ネジ切り部22のサイズは、これに限定されるものではないが、外径は2φ〜3φ程度、長さは2mm〜3mm程度、外内径差は0.3mm〜0.5mm程度とすればよい。 The threaded portion 22 has a cylindrical shape, and a female screw is formed on the inner wall thereof for screwing with the threaded portion 38. Further, the outer wall thereof can be connected to an opening at an adjacent position of the mounting target receiving portion 10 by press fitting or the like. The size of the threaded portion 22 is not limited to this, but the outer diameter is about 2φ to 3φ, the length is about 2 mm to 3 mm, and the outer inner diameter difference is about 0.3 mm to 0.5 mm. Just do it.

片部24,26は、ネジ切り部22と一体的に形成されており、ネジ切り部22の上部に位置する一対のものである。片部24,26は、座面部36に対向する位置に、ネジ30を螺合することで開状態となって、凹部の側面に押圧される面状部24A,26Aを有する。面状部24A,26Aは、それぞれ、ここでは曲面状としている。片部24,26は、それらの中央部分は、座面部36に対応する角度の円錐状部24B,26Bを有するが、このような形状とすることは必須ではない。 The single portions 24 and 26 are integrally formed with the thread cutting portion 22, and are a pair of ones located above the thread cutting portion 22. The single portions 24 and 26 have planar portions 24A and 26A that are opened by screwing a screw 30 at a position facing the seat surface portion 36 and pressed against the side surface of the recess. The planar portions 24A and 26A have a curved surface shape, respectively. The single portions 24, 26 have conical portions 24B, 26B at an angle corresponding to the seat surface portion 36 in the central portion thereof, but it is not essential to have such a shape.

なお、片部24,26のサイズは、これに限定されるものではないが、各々の幅は3mm〜4mm程度、長さは全体として5φ〜7φ程度、厚さは1mm〜2mm程度とすればよい。この例では、円錐状部24B,26Bは、それぞれ軸心方向に対して40°としている。 The size of the pieces 24 and 26 is not limited to this, but if the width of each is about 3 mm to 4 mm, the length is about 5φ to 7φ as a whole, and the thickness is about 1 mm to 2 mm. good. In this example, the conical portions 24B and 26B are set to 40 ° with respect to the axial direction, respectively.

シリンダーの横溝が凹部となる場合には、ネジ30を締めたり緩めたりする時の進行方向と横溝の長手方向とが直交する態様で取付装置100を取り付けることになるので、片部24,26のように2つ割りすることで形成されるものでよい。 When the lateral groove of the cylinder becomes a recess, the mounting device 100 is mounted in such a manner that the traveling direction when tightening or loosening the screw 30 and the longitudinal direction of the lateral groove are orthogonal to each other. It may be formed by dividing it in two as described above.

また、ネジ30を締めたり緩めたりする時の進行方向と凹部の長手方向とが同じ方向である場合には、同様に2つ割りのものでもよいが、片部24,26に代えてこれらを3つ割り又は4つ割りのようなものとしてもよい。こうすると、凹部の側面に対する押圧面積、押圧数が増え、より安定的な取り付けが可能となる。 Further, when the traveling direction when tightening or loosening the screw 30 and the longitudinal direction of the recess are the same, the screw 30 may be split in half in the same manner, but these may be used instead of the single portions 24 and 26. It may be divided into three or four. By doing so, the pressing area and the number of pressing against the side surface of the concave portion increase, and more stable mounting becomes possible.

頭部32は、頂部が平面状であり、座面部36が円錐状とされている。頭部32の頂部の形状は、図2,図3に示す態様に限定されるものではなく、半球状のような形状としてもよい。なお、頭部32のサイズは、これに限定されるものではないが、幅は3mm〜4mm程度、丈は全体として1.0mm〜1.5mm程度とすればよい。 The top of the head 32 is flat, and the seat 36 is conical. The shape of the top of the head 32 is not limited to the mode shown in FIGS. 2 and 3, and may be a hemispherical shape. The size of the head 32 is not limited to this, but the width may be about 3 mm to 4 mm and the length may be about 1.0 mm to 1.5 mm as a whole.

工具穴34は、マイナスドライバーなどの工具によって、ネジ30を締めたり緩めたりできるものである。工具穴34の形状は、図2,図3に示すものに限定されず、例えば、プラスドライバー、六角レンチなどの他の工具に対応する形状としてもよい。工具穴34の深さは、これに限定されるものではないが、頭部32の丈の半分程度とすればよい。 The tool hole 34 can be used to tighten or loosen the screw 30 with a tool such as a flat-blade screwdriver. The shape of the tool hole 34 is not limited to that shown in FIGS. 2 and 3, and may be a shape corresponding to other tools such as a Phillips screwdriver and a hexagon wrench. The depth of the tool hole 34 is not limited to this, but may be about half the length of the head 32.

座面部36は、ネジ30をネジ受け部20に螺合することで、片部24,26を開状態とするためのものであり、円錐状をしている。座面部36は、いわゆる皿ネジのようなものということになる。これに限定されるものではないが、座面部36の円錐状の角度は、例えば、ネジ部38の軸心方向に対して20°〜45°程度の範囲から適宜選択し、座面部36の丈は、例えば、1.5mm〜2,0mm程度とすればよい。 The seat surface portion 36 is for opening the single portions 24 and 26 by screwing the screw 30 into the screw receiving portion 20, and has a conical shape. The seat surface portion 36 is like a so-called countersunk screw. Although not limited to this, the conical angle of the seat surface portion 36 is appropriately selected from the range of about 20 ° to 45 ° with respect to the axial direction of the screw portion 38, and the length of the seat surface portion 36 is, for example. May be, for example, about 1.5 mm to 2.0 mm.

この例では、ネジ部38の軸心方向に対して30°としている。すなわち、座面部36に係る当該角度は、片部24,26に係る対応御する角度よりも、片部24,26を螺合時に開状態としやくするために、小さくしている。 In this example, it is set to 30 ° with respect to the axial direction of the screw portion 38. That is, the angle related to the seat surface portion 36 is made smaller than the corresponding angle related to the single portions 24 and 26 in order to make the single portions 24 and 26 open at the time of screwing.

ネジ部38は、ネジ切り部22に対して螺合されるものである。したがって、その外壁にはネジ切り部22の内壁の雌ネジに対応する雄ネジが形成されている。ネジ部38のサイズは、これに限定されるものではないが、幅はネジ切り部22の内壁に対応させ、丈は全体として1.0mm〜1.5mm程度とすればよい。 The threaded portion 38 is screwed into the threaded portion 22. Therefore, a male screw corresponding to the female screw on the inner wall of the threaded portion 22 is formed on the outer wall thereof. The size of the threaded portion 38 is not limited to this, but the width may correspond to the inner wall of the threaded portion 22, and the overall length may be about 1.0 mm to 1.5 mm.

ただし、ネジ部38の先端が、もっとも螺合した地点で、シリンダーの横溝の底面などを傷つけないように、取付装置100の底面よりも上にあるようにしなければならない。 However, the tip of the screw portion 38 must be above the bottom surface of the mounting device 100 so as not to damage the bottom surface of the lateral groove of the cylinder at the most screwed point.

図4は、図1に示す取付装置100を用いてシリンダーの横溝130にセンサを取り付ける状態を示す模式図である。図4には、ネジ30を含む取付装置100と、取付工具であるマイナスドライバー160のほかに、シリンダーのピストン110と、ピストン110を包含するエアシリンダー本体120とを示している。 FIG. 4 is a schematic view showing a state in which the sensor is attached to the lateral groove 130 of the cylinder by using the attachment device 100 shown in FIG. FIG. 4 shows a mounting device 100 including a screw 30, a flat-blade screwdriver 160 as a mounting tool, a cylinder piston 110, and an air cylinder body 120 including the piston 110.

エアシリンダー本体120は、取付装置100によってセンサが取り付けられる横溝130が形成されている。なお、横溝130に代えて、穴、窪みが形成されている場合もある。 The air cylinder body 120 is formed with a lateral groove 130 to which the sensor is mounted by the mounting device 100. In addition, instead of the lateral groove 130, a hole or a depression may be formed.

まず、取付装置100を、エアシリンダー本体120の側面に形成されている横溝130に差し込み、所望の位置に合わせる。つづいて、取付装置100に設けられているネジ受け部20にネジ30を位置合わせしてから、マイナスドライバー160を用いて、ネジ30を締める。 First, the mounting device 100 is inserted into the lateral groove 130 formed on the side surface of the air cylinder body 120 and adjusted to a desired position. Subsequently, after aligning the screw 30 with the screw receiving portion 20 provided in the mounting device 100, the screw 30 is tightened using a flat-blade screwdriver 160.

こうすると、ネジ受け部20の片部24,26を開状態とし、横溝130の側面に当接され、取付装置100が横溝130の側面に押圧され、エアシリンダー本体120に取り付けられる。 In this way, the single portions 24 and 26 of the screw receiving portion 20 are opened, abutted against the side surface of the lateral groove 130, the mounting device 100 is pressed against the side surface of the lateral groove 130, and is attached to the air cylinder body 120.

このため、本実施形態の取付装置100によれば、エアシリンダー本体120の横溝130に対してセンサを取り付ける際に、横溝130の底面に傷が生じる事態を回避することができる。 Therefore, according to the mounting device 100 of the present embodiment, it is possible to avoid a situation in which the bottom surface of the lateral groove 130 is scratched when the sensor is mounted on the lateral groove 130 of the air cylinder body 120.
