Description

本発明は、外掛け式感知器を備えたリニアスライドウェイに関し、主に、必要に応じてリニアガイドウェイに感知器を取り付けるか否かを選択でき、他に特殊構造のスライダまたなエンドカバーの製作必要がなく、全リニアガイドウェイ、またはそのスライダ、エンドカバーを共通効果に達成できるリニアスライドウェイに関する。   The present invention relates to a linear slide way equipped with an externally mounted sensor, and can mainly select whether or not the sensor is attached to the linear guide way as needed. In addition, the slider or end cover of a special structure can be selected. The present invention relates to a linear slide way that can achieve all the linear guideways or their sliders and end covers with a common effect without the need for manufacturing.

台湾の第８８２０３３１９号実用新案登録の「磁気感知スケール機能を備えたリニアガイドウェイ」（以下、先願と略称）を参照するように、この先願は、スライダの所在位置をフィードバックでき、またはスライダの変位距離を計算できる。磁気感知素子はエンドカバーに設置されるとともに磁気テープをレールの真上に設置することにより、スライダの仕上げコストを抑え、磁気テープと磁気感知素子間の距離変化しない効果を達成できる。しかし、この先願は、両相異した構造のエンドカバーによりスライダの両側に固定しなければならないため、両側のエンドカバーを共用できないこととなり、製造上、両金型を製作して二回相異する仕上げ工程によりコストが高くなる問題に対して、さらに改善する必要がある。
台湾実用新案登録第８８２０３３１９号公報 As referred to “Linear Guide Way with Magnetic Sensing Scale Function” (hereinafter referred to as “Prior Application”) registered in Utility Model Registration No. 88203319 in Taiwan, this prior application can feed back the location of the slider, Displacement distance can be calculated. By installing the magnetic sensing element on the end cover and placing the magnetic tape directly above the rail, it is possible to reduce the finishing cost of the slider and achieve the effect that the distance between the magnetic tape and the magnetic sensing element does not change. However, this prior application must be fixed to both sides of the slider with end covers of different structures, so the end covers on both sides cannot be shared. There is a need for further improvement to the problem of high cost due to the finishing process.
Taiwan Utility Model Registration No. 8203319

前記の第８８２０３３１９号実用新案登録の「磁気感知スケール機能を備えたリニアガイドウェイ」の欠点に鑑みて、本願の発明者は、これに関する製品について、長年の生産販売の経験を生かし、研究に努力して設計改良しつつ、さらにサンプルを作成して実験を繰り返す上で、改良を重ね、漸く下記の目的を達成できるリニアスライドウェイを案出することができた。   In light of the shortcomings of the "8820319 Utility Model Registration" Linear Guideway with Magnetic Sensing Scale Function "described above, the inventors of the present application have made many years of experience in production and sales of products related to this. While improving the design, it was possible to devise a linear slide way that could achieve the following objectives by repeatedly making further samples and repeating the experiment.

即ち、本発明は、主に磁気感知スケールの感知器がエンドカバーに設置され、スライダの両側に固定されたエンドカバー構造を共用できるように同一に設けられ、金型の製作、またはエンドカバーの二重加工によるコストの低減をすることを目的とする。   That is, according to the present invention, a sensor of a magnetic sensing scale is mainly provided on the end cover, and is provided so as to share the end cover structure fixed on both sides of the slider. The purpose is to reduce the cost by double machining.

本発明は、次に、感知器中のの感知板により磁気スケールとの距離を調整でき、ガイドウェイとスライダの異なる大きさに応じて感知器の適用性をさらに広げることを目的とする。   Next, the present invention aims to further expand the applicability of the sensor according to the different sizes of the guideway and the slider by adjusting the distance from the magnetic scale by the sensing plate in the sensor.

The sensor is provided with a fitting base that protrudes on the opposite side of the scraper, and a concave groove is formed on the side of the fitting base that faces the scraper, and is used for fitting the fitting. The sensor is fixed on the end cover by a tightening method, and the sensor can engage the first seat and the second seat to limit the sensing element. The first seat has an L-shape and includes a vertical plate and a horizontal plate. The vertical plate forms a frame projecting on the opposite side of the second seat, and the upper and lower sides are spaced apart on the horizontal plate. An inverted L-shaped hanging block projecting in the direction is provided, and a gap is provided between the both hanging blocks, and a gap is also provided between the both hanging blocks and the horizontal plate. The second seat has a storage chamber, the opposing side surfaces of the first seat of the storage chamber form an opening, and the bottom of the storage chamber is hollow so as to form a hanging plate at the bottom of the storage chamber. A fitting base that is formed in a shape and protrudes from the other side surface of the storage chamber is formed, and a through hole that communicates with the storage chamber is provided in the insertion base. A line groove is provided on the side adjacent to the storage chamber, and a slit is formed between the line groove and the storage chamber to communicate the storage chamber with the line groove. The sensing element includes a sensing plate and a signal line which can be inserted between the two hanging blocks, and one end of the conductive wire of the signal line is connected to the insulating plate so as to protrude from the insulating line. The conducting wire has flexibility. The first seat can sandwich the corresponding hanging plates of the second seat by the both-hanging block and the lateral plate, and when pressed to the bottom, the frame of the first seat is It can be tightly stored in a two-seat storage chamber.

Between the two hanging blocks of the horizontal plate, a concave groove recessed downward is further provided, and the horizontal plate of the first seat body can be designed to have a different thickness.

本発明によれば、スライダ及び両エンドカバーは、余計に二重金型を開設して二回加工工程を介する必要がなく、そのため、リニアスライドウェイの製造コストを低減することができる。また、感知器が外掛け式を採用していることにより、リニアガイドウェイの必要に応じてスライダ変位距離を感知する機能を具備する必要があるか否かを選択でき、強い機動性を有し、在庫量を少なくすることができる。さらに、感知器の取り付け取り外しが極めて容易であるため、リニアガイドウェイと機具との取り付けに影響を及ぼすことはない。   According to the present invention, the slider and the both end covers do not need to have an extra double mold and go through a two-time machining step, and therefore the manufacturing cost of the linear slide way can be reduced. In addition, by adopting an externally mounted detector, it is possible to select whether or not it is necessary to have a function of detecting the slider displacement distance according to the necessity of the linear guideway, and it has strong mobility. , Inventory quantity can be reduced. Furthermore, since the attachment and removal of the sensor is extremely easy, the attachment between the linear guideway and the instrument is not affected.
