Description

本発明は、案内レールに設けた取り付け穴を塞ぐカバーベルトを備えたリニアガイド装置に関する。   The present invention relates to a linear guide device including a cover belt that closes a mounting hole provided in a guide rail.

リニアガイド装置は、図５に示すように、案内レール１とスライダ２と複数個の転動体３とを備えている。案内レール１およびスライダ２は、互いに対向配置されて転動体３の転動通路を形成する転動溝（転動面）１１，２１を有する。スライダ２は、転動体３の戻し通路２２と、この戻し通路２２と前記転動通路とを連通させる方向転換路を有する。そして、前記転動通路、戻し通路、および方向転換路で転動体の循環経路が構成され、この循環経路内を転動体３が循環することにより、案内レール１およびスライダ２の一方が他方に対して相対的に直線運動する。   As shown in FIG. 5, the linear guide device includes a guide rail 1, a slider 2, and a plurality of rolling elements 3. The guide rail 1 and the slider 2 have rolling grooves (rolling surfaces) 11 and 21 that are arranged to face each other and form a rolling path of the rolling element 3. The slider 2 has a return path 22 of the rolling element 3 and a direction changing path that connects the return path 22 and the rolling path. The rolling path, the return path, and the direction changing path constitute a circulation path for the rolling elements, and the rolling element 3 circulates in the circulation path so that one of the guide rail 1 and the slider 2 is in relation to the other. Move relatively linearly.

リニアガイド装置の案内レール１には、基台等の被取付部にボルトを用いて取り付けるための取り付け穴４が形成されており、リニアガイド装置の使用時に取り付け穴４にゴミが入ることを防止する必要がある。そのために、案内レール上面に長手方向全長に亙って溝を形成し、この溝に板状のカバー部材を配置することが提案されている。
例えば、下記の特許文献１には、案内レール上面の溝に薄板状のカバー部材を張力を付与した状態で配置するために、カバー部材の長手方向両端を、カバー部材を引っ張る連結部材を介して案内レールの端面に固定することが記載されている。 The guide rail 1 of the linear guide device is provided with a mounting hole 4 for mounting to a mounting portion such as a base using a bolt, and prevents dust from entering the mounting hole 4 when the linear guide device is used. There is a need to. For this purpose, it has been proposed to form a groove over the entire length in the longitudinal direction on the upper surface of the guide rail and arrange a plate-like cover member in this groove.
For example, in Patent Document 1 below, in order to dispose a thin cover member in a groove on the upper surface of the guide rail in a tensioned state, both ends in the longitudinal direction of the cover member are connected via a connecting member that pulls the cover member. It is described that it is fixed to the end face of the guide rail.

下記の特許文献２には、カバー部材の幅方向両端に、長手方向に延びる切り込みを形成することで板バネ状の保持条片を設け、この保持条片を案内レール上面の溝の側壁に弾性変形状態で接触させることで、カバー部材を取り付けることが記載されている。このカバー部材は、保持条片の切欠き部を下側に向けて取り付けられ、カバー部材の上面が案内レール上面の溝以外の面と同じ面一になっている。また、案内レール上面の溝の幅方向両端が複雑な形状（アンダカット）になっている。   In Patent Document 2 below, a leaf spring-like holding strip is provided by forming notches extending in the longitudinal direction at both ends in the width direction of the cover member, and this holding strip is elastically formed on the side wall of the groove on the upper surface of the guide rail. It is described that the cover member is attached by contacting in a deformed state. The cover member is attached with the notch portion of the holding strip facing downward, and the upper surface of the cover member is flush with the surface other than the groove on the upper surface of the guide rail. Further, both ends in the width direction of the groove on the upper surface of the guide rail have a complicated shape (undercut).

これらの特許文献に記載されたカバー部材は、案内レール上面の溝に対する密着性が高いが、溝形状が複雑になったり、部品点数が多くなったりする。よって、加工コストや組み立ての手間がかかる。
特開平８−２１９１５２号公報 特開２００２−８９５５８号公報 The cover members described in these patent documents have high adhesion to the groove on the upper surface of the guide rail, but the groove shape becomes complicated and the number of parts increases. Therefore, processing cost and assembly work are required.
JP-A-8-219152 JP 2002-89558 A

本発明の課題は、リニアガイド装置において、単純な構造で確実に、案内レール上面の溝にカバー部材が取り付けられるようにすることである。   An object of the present invention is to ensure that a cover member is attached to a groove on an upper surface of a guide rail with a simple structure in a linear guide device.

上記課題を解決するために、本発明は、案内レールと、スライダと、複数個の転動体と、を備え、案内レールおよびスライダは、互いに対向配置されて転動体の転動通路を形成する転動面を有し、案内レールは、被取付部にボルトを用いて取り付けるための取り付け穴を有し、スライダは、さらに、転動体の戻し通路と、前記戻し通路と前記転動通路とを連通させる方向転換路を有し、前記転動通路、戻し通路、および方向転換路で転動体の循環経路が構成され、前記循環経路を転動体が循環することにより、案内レールおよびスライダの一方が他方に対して相対的に直線運動するリニアガイド装置において、前記案内レールの上面に、長手方向に延びる溝が、前記取り付け穴の開口が全て前記溝内に配置される幅で形成され、この溝の壁面は底面に対してほぼ垂直に形成され、前記溝に配置されるカバーベルトを有し、このカバーベルトは、前記溝の底面に対応させた底板と、この底板の幅方向両端から鈍角で立ち上がる側板とからなり、前記カバーベルトは、前記底板が前記溝の底面に接触し、前記側板が前記溝の壁面に弾性変形状態で取り付けられ、前記側板の立ち上がり端が前記壁面に接触しているリニアガイド装置を提供する。 In order to solve the above-described problems, the present invention includes a guide rail, a slider, and a plurality of rolling elements, and the guide rail and the slider are arranged to face each other to form a rolling passage of the rolling element. The guide rail has a mounting hole for mounting to the mounted portion using a bolt, and the slider further communicates the return passage of the rolling element, the return passage, and the rolling passage. A rolling path of the rolling element is constituted by the rolling path, the return path, and the direction switching path. When the rolling element circulates in the circulating path, one of the guide rail and the slider is the other. In the linear guide device that linearly moves relative to the guide rail, a groove extending in the longitudinal direction is formed on the upper surface of the guide rail so as to have a width in which the openings of the mounting holes are all disposed in the groove. Wall A cover belt formed substantially perpendicular to the bottom surface and disposed in the groove; the cover belt corresponding to the bottom surface of the groove; and a side plate rising at an obtuse angle from both ends of the bottom plate in the width direction. made, the cover belt, the bottom plate is in contact with the bottom surface of the groove, the side plate is mounted in a resiliently deformed state on the wall of the groove, the linear guide device the rising edge of the side plates that are in contact with the wall surface I will provide a.

本発明のリニアガイド装置によれば、単純な構造で確実に、案内レール上面の溝にカバーベルトが取り付けられた状態にすることができる。   According to the linear guide device of the present invention, the cover belt can be securely attached to the groove on the upper surface of the guide rail with a simple structure.

以下、本発明の実施形態について説明する。
図１は、第１実施形態のリニアガイド装置を構成する案内レールの長手方向一端部を示す斜視図であり、カバーベルトを取り付ける前の状態（ａ）と取り付けた後の状態（ｂ）を示す。図２は図１（ｂ）のＡ部分の拡大図である。
図１（ａ）に示すように、案内レール１の上面１２に、長手方向全体に延びる溝１３が、取り付け穴４の開口が全て溝１３内に配置される幅で形成されている。溝１３の壁面１３ａは底面１３ｂに対してほぼ垂直に形成されている。 Hereinafter, embodiments of the present invention will be described.
FIG. 1 is a perspective view showing one end portion in the longitudinal direction of a guide rail constituting the linear guide device of the first embodiment, showing a state (a) before attaching a cover belt and a state (b) after being attached. . FIG. 2 is an enlarged view of a portion A in FIG.
As shown in FIG. 1A, a groove 13 extending in the entire longitudinal direction is formed on the upper surface 12 of the guide rail 1 with a width that allows all the openings of the mounting holes 4 to be disposed in the groove 13. The wall surface 13a of the groove 13 is formed substantially perpendicular to the bottom surface 13b.

カバーベルト５は、底板５１と、底板５１の幅方向両端から鈍角（例えば９５〜１２０°）で立ち上がる側板５２とからなる。底板５１の寸法は、幅が溝１３の底面１３ｂより少し狭く、長さが溝１３と同じである。このカバーベルト５は、アルミニウム合金や鋼からなる薄板を、引き抜き加工、押出成形、または曲げ加工（ロールフォーミングなど）することで得られる。   The cover belt 5 includes a bottom plate 51 and side plates 52 that rise at an obtuse angle (for example, 95 to 120 °) from both ends of the bottom plate 51 in the width direction. The dimensions of the bottom plate 51 are slightly narrower than the bottom surface 13 b of the groove 13 and the length is the same as that of the groove 13. The cover belt 5 can be obtained by drawing, extruding, or bending (roll forming, etc.) a thin plate made of an aluminum alloy or steel.

例えば、案内レール１の溝１３の幅が１５ｍｍで、深さが１．３ｍｍのとき、カバーベルト５の底板５１の幅を１４ｍｍ、側板５２の立ち上がり高さを１．２ｍｍとし、鋼板等からなる底板５１および側板５２の厚さを０．３ｍｍとする。
このカバーベルト５を、側板５２側を上に向けて、案内レール１の溝１３に上側から嵌め入れる。その際に、カバーベルト５は、両側板５２が互いに近づくように弾性変形した後、元に戻ろうとする力で溝１３の壁面１３ａに押し付けられる。これにより、図１（ｂ）および図２に示すように、カバーベルト５の底板５１が溝１３の底面１３ｂに接触し、側板５２が溝１３の壁面１３ａに弾性変形状態で取り付けられる。この取り付け状態で、側板５２の底板５１からの立ち上がり角度は、取り付け前の状態の角度より小さくなっている。 For example, when the width of the groove 13 of the guide rail 1 is 15 mm and the depth is 1.3 mm, the width of the bottom plate 51 of the cover belt 5 is 14 mm, the rising height of the side plate 52 is 1.2 mm, and is made of a steel plate or the like. The thickness of the bottom plate 51 and the side plate 52 is set to 0.3 mm.
The cover belt 5 is fitted into the groove 13 of the guide rail 1 from above with the side plate 52 side facing up. At that time, the cover belt 5 is elastically deformed so that the both side plates 52 come close to each other, and then is pressed against the wall surface 13 a of the groove 13 with a force of returning to the original state. Thereby, as shown in FIGS. 1B and 2, the bottom plate 51 of the cover belt 5 comes into contact with the bottom surface 13 b of the groove 13, and the side plate 52 is attached to the wall surface 13 a of the groove 13 in an elastically deformed state. In this attached state, the rising angle of the side plate 52 from the bottom plate 51 is smaller than the angle in the state before the attachment.

この実施形態のリニアガイド装置によれば、案内レール１へのカバーベルト５の取付を、単純な構造（底面１３ｂにほぼ垂直な壁面１３ａを有する溝１３に対する、底板５１とその幅方向両端から鈍角で立ち上がる側板５２とからなるカバーベルト５の嵌め合い）で、確実に行うことができる。よって、特許文献１および２のカバー部材を用いる場合と比較して、カバー部材の加工コストが低減でき、組み立ての作業性が向上する。   According to the linear guide device of this embodiment, the cover belt 5 can be attached to the guide rail 1 with an obtuse angle from the bottom plate 51 and both ends in the width direction of the groove 13 having the wall surface 13a substantially perpendicular to the bottom surface 13b. The fitting of the cover belt 5 consisting of the side plate 52 that rises in step 3) can be performed reliably. Therefore, compared with the case where the cover member of patent documents 1 and 2 is used, the processing cost of a cover member can be reduced and the workability of an assembly improves.

図３は、第２実施形態のリニアガイド装置を構成する案内レールの長手方向一端を示す斜視図である。図３（ａ）はカバーベルトを取り付けた後の状態を示し、図３（ｂ）は図３（ａ）のＢ部分の拡大図である。
この実施形態では、カバーベルト５の底板５１の厚さを第１実施形態よりも厚く形成している。これ以外の点は第１実施形態と同じである。 FIG. 3 is a perspective view showing one end in the longitudinal direction of the guide rail constituting the linear guide device of the second embodiment. FIG. 3A shows a state after the cover belt is attached, and FIG. 3B is an enlarged view of a portion B in FIG.
In this embodiment, the bottom plate 51 of the cover belt 5 is formed thicker than the first embodiment. Other points are the same as in the first embodiment.

例えば、案内レール１の溝１３の幅が１５ｍｍで、深さが１．３ｍｍのとき、カバーベルト５の底板５１の幅を１４ｍｍ、側板５２の立ち上がり高さを１．２ｍｍとし、鋼板等からなる底板５１の厚さを０．６ｍｍ、側板５２の厚さを０．３ｍｍとする。
第２実施形態のカバーベルト５は、第１実施形態のカバーベルト５よりも底板５１が幅方向に変形しにくいため、溝１３からさらに外れにくくなる。 For example, when the width of the groove 13 of the guide rail 1 is 15 mm and the depth is 1.3 mm, the width of the bottom plate 51 of the cover belt 5 is 14 mm, the rising height of the side plate 52 is 1.2 mm, and is made of a steel plate or the like. The thickness of the bottom plate 51 is 0.6 mm, and the thickness of the side plate 52 is 0.3 mm.
In the cover belt 5 of the second embodiment, the bottom plate 51 is less likely to be deformed in the width direction than the cover belt 5 of the first embodiment.

図４は、第３実施形態のリニアガイド装置を構成する案内レールの長手方向一端を示す斜視図である。図４（ａ）は、カバーベルトを取り付けた後の状態を示し、図４（ｂ）は図４（ａ）のＣ部分の拡大図である。
この実施形態では、カバーベルト５の側板５２の厚さを第１実施形態よりも薄く形成している。これ以外の点は第１実施形態と同じである。 FIG. 4 is a perspective view showing one longitudinal end of the guide rail constituting the linear guide device of the third embodiment. Fig.4 (a) shows the state after attaching a cover belt, FIG.4 (b) is an enlarged view of C part of Fig.4 (a).
In this embodiment, the thickness of the side plate 52 of the cover belt 5 is made thinner than that of the first embodiment. Other points are the same as in the first embodiment.

例えば、案内レール１の溝１３の幅が１５ｍｍで、深さが１．３ｍｍのとき、カバーベルト５の底板５１の幅を１４ｍｍ、側板５２の立ち上がり高さを１．２ｍｍとし、鋼板等からなる底板５１の厚さを０．３ｍｍ、側板５２の厚さを０．１５ｍｍとする。
第３実施形態のカバーベルト５は、第１実施形態のカバーベルト５よりも側板５２が変形し易いため、溝１３への取付が容易にできる。また、底板５１を側板５２よりも厚く形成しているため、底板５１も側板５２と同じように薄くした場合と比較して、側板５２の変形に伴って底板５１に生じる影響を軽減できる。 For example, when the width of the groove 13 of the guide rail 1 is 15 mm and the depth is 1.3 mm, the width of the bottom plate 51 of the cover belt 5 is 14 mm, the rising height of the side plate 52 is 1.2 mm, and is made of a steel plate or the like. The thickness of the bottom plate 51 is 0.3 mm, and the thickness of the side plate 52 is 0.15 mm.
The cover belt 5 of the third embodiment can be easily attached to the groove 13 because the side plate 52 is more easily deformed than the cover belt 5 of the first embodiment. In addition, since the bottom plate 51 is formed thicker than the side plate 52, the influence on the bottom plate 51 due to the deformation of the side plate 52 can be reduced as compared with the case where the bottom plate 51 is also thinned similarly to the side plate 52.
