Description

この発明は、リニアガイド装置の案内レールの上面にカバーを取り付けるための取付部材に関する。   The present invention relates to an attachment member for attaching a cover to an upper surface of a guide rail of a linear guide device.

従来より、リニアガイド装置の案内レールの上面には、防塵等の目的で、カバーを取り付けることが行われている。
下記の特許文献１には、案内レールの上面に取り付けるカバーとして、案内レールの取付穴（被取付部材に案内レールをボルトで締結するための挿通穴）に係合する取付穴係合部が、カバー本体に固着されるか、合成樹脂でカバー本体と一体に成形されているものが記載されている。 Conventionally, a cover is attached to the upper surface of a guide rail of a linear guide device for the purpose of dust prevention or the like.
In Patent Document 1 below, as a cover to be attached to the upper surface of the guide rail, an attachment hole engaging portion that engages with an attachment hole of the guide rail (an insertion hole for fastening the guide rail to the attached member with a bolt), It is described as being fixed to the cover body or molded integrally with the cover body with synthetic resin.

下記の特許文献２には、幅方向中央部の両端から側面部が屈曲している形状のカバーであって、前記側面部は、案内レールの上側角部（上面と側面とによる角部）のアンダーカット角度に対応させて、幅方向中央部に対して鋭角となる斜面状に形成されているものが記載されている。
特開平８−２４７１４６号公報 特許２７１９９８５号公報 The following Patent Document 2 is a cover having a shape in which side portions are bent from both ends of a central portion in the width direction, and the side portion is an upper corner portion (a corner portion formed by an upper surface and a side surface) of a guide rail. In correspondence with the undercut angle, there is described what is formed in an inclined surface having an acute angle with respect to the central portion in the width direction.
JP-A-8-247146 Japanese Patent No. 2719985

しかしながら、特許文献１に記載された、カバー本体に取付穴係合部が固着または一体成形されているものでは、案内レールが長い場合や、案内レールを連結して数十メートルに及ぶようなストロークに対応させる場合には、取付穴係合部のカバー本体に対する位置精度を厳しくしないと、多数ある取付穴係合部が、案内レールの対応する取付穴にきちんと嵌まらない可能性が高くなる。同様に、案内レールに対する取付穴の位置精度も厳しくしないと、各取付穴に対応する取付穴係合部が嵌まらない可能性が高くなる。   However, in the case where the mounting hole engaging portion is fixed or integrally formed in the cover body described in Patent Document 1, when the guide rail is long or the guide rail is connected, the stroke extends to several tens of meters. If the position accuracy of the mounting hole engaging portion with respect to the cover body is not strict, there is a high possibility that a large number of mounting hole engaging portions will not fit properly in the corresponding mounting holes of the guide rail. . Similarly, if the positional accuracy of the mounting hole with respect to the guide rail is not strict, there is a high possibility that the mounting hole engaging portion corresponding to each mounting hole will not fit.

特許文献２に記載されたカバーは、案内レールの上側角部に転動体軌道面が形成されているタイプのリニアガイド装置には適用できない。このタイプのリニアガイド装置では、従来、案内レールの上面にカバーを収納する凹部を機械加工で設けることが行われているが、製造コストが高くなる。また、長尺な案内レールの上面に凹部を形成するためには大型の加工機が必要となり、設備上の制約が大きい。   The cover described in Patent Document 2 cannot be applied to a linear guide device of a type in which a rolling element raceway surface is formed at the upper corner of the guide rail. In this type of linear guide device, conventionally, a recess for housing the cover is provided on the upper surface of the guide rail by machining, but the manufacturing cost increases. Moreover, in order to form a recessed part in the upper surface of a long guide rail, a large sized processing machine is needed and the restrictions on an installation are large.

本発明は、このような従来技術の問題点に着目してなされたものであり、取付穴係合部の案内レールの取付穴に対する位置精度を厳しくしなくても、案内レールの上面にカバーが容易に取り付けられ、しかも、案内レールに追加の加工をすることなく、案内レールの上側角部に転動体軌道面が形成されているタイプのリニアガイド装置にも適用できるカバー取付部材を提供することを課題とする。   The present invention has been made paying attention to such problems of the prior art, and a cover is provided on the upper surface of the guide rail without strict positioning accuracy of the mounting hole engaging portion with respect to the mounting hole of the guide rail. Provided is a cover mounting member that can be easily mounted and can be applied to a linear guide device of a type in which a rolling element raceway surface is formed at an upper corner of the guide rail without additional processing of the guide rail. Is an issue.

上記課題を解決するために、本発明は、スライダおよび転動体とともにリニアガイド装置を構成する案内レールの上面に、幅方向中央部の両端から側面部が屈曲している形状のカバーを取り付けるための取付部材であって、案内レールの上面に開口する取付穴に係合する取付穴係合部と、案内レールの上面に接触状態で配置される板状部と、からなり、前記板状部の幅方向両端面が前記カバーの側面部との係合部を成し、前記取付穴係合部が、前記板状部の案内レールに接触させる側の面に一体化されていることを特徴とする案内レールへのカバー取付部材を提供する。   In order to solve the above problems, the present invention is for attaching a cover having a shape in which side portions are bent from both ends of a central portion in the width direction to the upper surface of a guide rail that constitutes a linear guide device together with a slider and a rolling element. An attachment member, comprising: an attachment hole engaging portion that engages with an attachment hole that opens on the upper surface of the guide rail; and a plate-like portion that is arranged in contact with the upper surface of the guide rail, Both end surfaces in the width direction form an engaging portion with the side surface portion of the cover, and the mounting hole engaging portion is integrated with a surface of the plate-like portion on a side to be brought into contact with the guide rail. Provided is a cover attaching member to the guide rail.

本発明のカバー取付部材によれば、板状部の幅を案内レールの上面の幅より小さくすることで、案内レールに追加の加工をすることなく、上面と側面との角部に転動体軌道面を有する案内レールの上面に、案内レールの上面の幅より小さい幅のカバーを取り付けることができる。
また、長尺なカバーを取り付ける際には、板状部の長さがカバーの長さより短く、例えば、板状部の長さ方向の両端部に取付穴係合部を設けた複数の取付部材を用意すれば、取付穴係合部の案内レールの取付穴に対する位置精度を厳しくしなくても容易に取り付けることができる。
使用するカバーの側面部を、幅方向中央部に対して鋭角となる斜面状に形成されているものとし、本発明の取付部材の前記板状部の幅方向両端面を、前記側面部の斜面に対応する、幅方向寸法が案内レールとの接触面側で小さくなる斜面状に形成することで、カバーがカバー取付部材から外れにくくなる。 According to the cover mounting member of the present invention, the width of the plate-like portion is made smaller than the width of the upper surface of the guide rail, so that the rolling element track is formed at the corner between the upper surface and the side surface without additional processing on the guide rail. A cover having a width smaller than the width of the upper surface of the guide rail can be attached to the upper surface of the guide rail having a surface.
When attaching a long cover, the length of the plate-like portion is shorter than the length of the cover, for example, a plurality of attachment members provided with attachment hole engaging portions at both ends in the length direction of the plate-like portion Can be easily installed without strict positioning accuracy of the mounting hole engaging portion with respect to the mounting hole of the guide rail.
The side surface portion of the cover to be used is formed into an inclined surface having an acute angle with respect to the center portion in the width direction, and both end surfaces in the width direction of the plate-like portion of the mounting member of the present invention are inclined surfaces of the side surface portion. The cover is less likely to be detached from the cover mounting member by forming a slanted shape with a width-wise dimension that is smaller on the contact surface side with the guide rail.

本発明のカバー取付部材において、前記取付穴係合部が、案内レールの取付穴に対して締め代で係止される形状とされていると、前記取付穴係合部が案内レールの取付穴から外れにくくなる。また、この場合に、前記取付穴係合部が合成樹脂製の突起であると、案内レールの取付穴の金属面に押しつけられて締め代の部分の合成樹脂が削れて、削りかすが板状部と案内レールの上面との間に入り易くなる。合成樹脂の削りかすが取付部材の板状部と案内レールの上面との間に入ると、カバーが浮き上がり、スライダと接触する可能性が高くなる。よって、これを避けるために、前記板状部の前記突起の周囲となる部分に、案内レールの上面と接触しない逃げ部を設けることが好ましい。   In the cover mounting member of the present invention, when the mounting hole engaging portion is shaped to be locked with a tightening margin with respect to the mounting hole of the guide rail, the mounting hole engaging portion is the mounting hole of the guide rail. It becomes difficult to come off. Also, in this case, if the mounting hole engaging portion is a synthetic resin projection, the synthetic resin at the fastening portion is pressed against the metal surface of the mounting hole of the guide rail, and the shaving is a plate-like portion. And the upper surface of the guide rail. When the synthetic resin shavings enter between the plate-like portion of the mounting member and the upper surface of the guide rail, the cover is lifted and the possibility of contact with the slider increases. Therefore, in order to avoid this, it is preferable to provide an escape portion that does not come into contact with the upper surface of the guide rail in a portion around the protrusion of the plate-like portion.

本発明のカバー取付部材において、前記取付穴係合部は合成樹脂製の円柱状突起であり、内径が前記円柱状突起の直径より小さく、外径が前記取付穴の直径以下であるＣ形リングをさらに備えていることが好ましい。このカバー取付部材は、以下の方法で使用する。先ず、Ｃ形リングを案内レールの取付穴に入れる。次に、このＣ形リングに円柱状突起を嵌め入れると、Ｃ形リングの開口端間隔が拡がって、Ｃ形リングの外周が前記取付穴に押しつけられる。これにより、前記Ｃ形リングを介して円柱状突起が取り付け穴に係合され、前記板状部が案内レールの上面に接触状態で配置される。   In the cover mounting member of the present invention, the mounting hole engaging portion is a cylindrical protrusion made of synthetic resin, an inner diameter is smaller than a diameter of the cylindrical protrusion, and an outer diameter is equal to or smaller than the diameter of the mounting hole. Is preferably further provided. This cover mounting member is used in the following manner. First, the C-shaped ring is inserted into the guide rail mounting hole. Next, when a cylindrical protrusion is fitted into the C-shaped ring, the opening end interval of the C-shaped ring is widened, and the outer periphery of the C-shaped ring is pressed against the mounting hole. Thereby, the columnar protrusion is engaged with the attachment hole via the C-shaped ring, and the plate-like portion is arranged in contact with the upper surface of the guide rail.

このように前記Ｃ形リングをさらに備えることで、取付穴係合部を、合成樹脂製の突起であって、案内レールの取付穴に対して締め代で係止される形状にした場合のように、合成樹脂が削られることがないため、カバーが浮き上がることが防止できる。
本発明はまた、上面に開口する取付穴を有する案内レール、スライダ、および転動体を備え、案内レールの上面に、幅方向中央部の両端から側面部が屈曲している形状のカバーが取り付けられているリニアガイド装置において、案内レールの前記取付穴に係合する取付穴係合部と、案内レールの上面に接触状態で配置される板状部と、からなり、前記板状部の幅方向両端面が前記カバーの側面部との係合部を成し、前記取付穴係合部が、前記板状部の案内レールに接触させる側の面に一体化されているカバー取付部材により、前記カバーが取り付けられていることを特徴とするリニアガイド装置を提供する。 Thus, by further providing the C-shaped ring, the mounting hole engaging portion is a projection made of synthetic resin and is shaped to be locked to the mounting hole of the guide rail with a tightening margin. Further, since the synthetic resin is not scraped, the cover can be prevented from being lifted.
The present invention also includes a guide rail having a mounting hole opened on the upper surface, a slider, and a rolling element, and a cover having a shape in which side portions are bent from both ends of the central portion in the width direction is attached to the upper surface of the guide rail. The linear guide device comprises: a mounting hole engaging portion that engages with the mounting hole of the guide rail; and a plate-like portion disposed in contact with the upper surface of the guide rail, the width direction of the plate-like portion Both end surfaces form an engagement portion with the side surface portion of the cover, and the attachment hole engagement portion is integrated with the surface of the plate-like portion on the side to be brought into contact with the guide rail. Provided is a linear guide device in which a cover is attached.

本発明の取付部材を用いることで、取付穴係合部の案内レールの取付穴に対する位置精度を厳しくしなくても、案内レールの上面にカバーが容易に取り付けられ、しかも、案内レールに追加の加工をすることなく、案内レールの上側角部に転動体軌道面が形成されているタイプのリニアガイド装置であっても、案内レールの上面に容易にカバーを取り付けることができる。   By using the mounting member of the present invention, the cover can be easily attached to the upper surface of the guide rail without strict positioning accuracy of the mounting hole engaging portion with respect to the mounting hole of the guide rail. Even if it is a linear guide device of the type in which the rolling element raceway surface is formed in the upper corner portion of the guide rail without processing, the cover can be easily attached to the upper surface of the guide rail.

以下、本発明の実施形態について説明する。
図１は、この実施形態のカバー取付部材１を示す斜視図である。図２は、この実施形態で用いるカバー２を示す斜視図である。図３は、図１のカバー取付部材１と、図２のカバー２と、このカバー２を取り付けるリニアガイド装置の案内レール３を一緒に示す斜視図である。図４は、図１のカバー取付部材１を用いて、図２のカバー２を案内レール３に取り付ける手順を説明する断面図である。 Hereinafter, embodiments of the present invention will be described.
FIG. 1 is a perspective view showing a cover mounting member 1 of this embodiment. FIG. 2 is a perspective view showing the cover 2 used in this embodiment. FIG. 3 is a perspective view showing together the cover attaching member 1 of FIG. 1, the cover 2 of FIG. 2, and the guide rail 3 of the linear guide device to which the cover 2 is attached. FIG. 4 is a cross-sectional view illustrating a procedure for attaching the cover 2 of FIG. 2 to the guide rail 3 using the cover attaching member 1 of FIG.

この案内レール３は金属製で、二対４列の転動体軌道面３１〜３４を有し、そのうちの一対の転動体軌道面３１，３２が、上面と側面との角部に形成されている。案内レール３には、上面から下面に貫通する穴が、案内レール３を被取付部材にボルトで締結するための取付穴４として形成されている。取付穴４は、図４に示すように、ボルト５の頭部５１を収める座ぐり部４１と、ボルト５の軸部５２を収める軸収納部４２とからなる。また、座ぐり部４１の上端に面取り部４３が形成されている。   The guide rail 3 is made of metal and has two-to-four rows of rolling element raceway surfaces 31 to 34, of which a pair of rolling element raceway surfaces 31 and 32 are formed at corners between the upper surface and the side surface. . A hole penetrating from the upper surface to the lower surface is formed in the guide rail 3 as an attachment hole 4 for fastening the guide rail 3 to the attached member with a bolt. As shown in FIG. 4, the mounting hole 4 includes a counterbore portion 41 that houses the head portion 51 of the bolt 5, and a shaft housing portion 42 that houses the shaft portion 52 of the bolt 5. A chamfered portion 43 is formed at the upper end of the spot facing portion 41.

カバー２は、長尺な鋼板をプレス加工により、幅方向中央部２１の両端から側面部２２が屈曲している形状としたものである。幅方向中央部２１の幅は、案内レール３の上面の幅方向寸法Ｄより小さく、取付穴４の面取り部４３の最大直径（案内レール３の上面に存在する開口円）より大きい。側面部２２は、幅方向中央部２１に対して鋭角（図４でθ＜９０°）となる斜面状に形成されている。   The cover 2 has a shape in which the side surface portion 22 is bent from both ends of the center portion 21 in the width direction by pressing a long steel plate. The width of the central portion 21 in the width direction is smaller than the width direction dimension D of the upper surface of the guide rail 3 and is larger than the maximum diameter of the chamfered portion 43 of the mounting hole 4 (open circle existing on the upper surface of the guide rail 3). The side surface portion 22 is formed in an inclined surface having an acute angle (θ <90 ° in FIG. 4) with respect to the central portion 21 in the width direction.

カバー取付部材１は合成樹脂製で、円柱体（取付穴係合部）１１と板状部１２とからなり、二個の円柱体１１が案内レール３の隣り合う取付穴４に対応させた配置で、板状部１２の一方の面（案内レールに接触させる側の面）に一体化されている。円柱体１１の直径Ａは、案内レール３の取付穴４の座ぐり部４１の直径Ｂより少し大きく、面取り部４３の最大直径より小さい。板状部１２の幅Ｃは、カバー２の幅方向中央部２１の幅の内寸に対応させた寸法である。板状部１２の幅方向両端面の案内レール３との接触面側は、カバー２の側面部２２の斜面に対応させた、幅方向寸法が案内レール３との接触面側で小さくなる斜面１２ａに形成されている。   The cover mounting member 1 is made of a synthetic resin, and includes a cylindrical body (mounting hole engaging portion) 11 and a plate-like portion 12, and the two cylindrical bodies 11 are arranged so as to correspond to the adjacent mounting holes 4 of the guide rail 3. Thus, it is integrated with one surface of the plate-like portion 12 (surface on the side in contact with the guide rail). The diameter A of the cylindrical body 11 is slightly larger than the diameter B of the counterbore portion 41 of the mounting hole 4 of the guide rail 3 and smaller than the maximum diameter of the chamfered portion 43. The width C of the plate-like part 12 is a dimension corresponding to the inner dimension of the width of the central part 21 in the width direction of the cover 2. The contact surface side with the guide rail 3 on both end surfaces in the width direction of the plate-like portion 12 corresponds to the inclined surface of the side surface portion 22 of the cover 2, and the inclined surface 12 a whose width direction dimension becomes smaller on the contact surface side with the guide rail 3. Is formed.

カバー２を案内レール３に取り付ける際には、先ず、案内レール３の取付穴４にボルト５を入れて、軸部５２の先端の雄ねじを基台等の被取付部に螺合させることにより、案内レール３を基台等にボルトで固定する。次に、カバー取付部材１を案内レール３の上に置いて、円柱体１１を取付穴４の面取り部４３に接触させる。図４（ａ）は、この状態を示す。   When attaching the cover 2 to the guide rail 3, first, by inserting a bolt 5 into the attachment hole 4 of the guide rail 3 and screwing the male screw at the tip of the shaft portion 52 to the attached portion such as the base, The guide rail 3 is fixed to the base or the like with bolts. Next, the cover mounting member 1 is placed on the guide rail 3 and the cylindrical body 11 is brought into contact with the chamfered portion 43 of the mounting hole 4. FIG. 4A shows this state.

次に、この状態で、カバー取付部材１の板状部１２の、円柱体１１の上側となる部分を叩いて、円柱体１１を弾性変形させながら取付穴４の座ぐり部４１内に入れて、板状部１２を案内レール３と接触させる。これにより、カバー取付部材１の円柱体１１が締め代で取付穴４の座ぐり部４１に係止され、板状部１２が案内レール３の上面に接触状態で配置される。このようにして、カバー取付部材１が案内レール３の上面に取り付けられる。図４（ｂ）は、この状態を示す。   Next, in this state, the upper part of the cylindrical body 11 of the plate-like part 12 of the cover mounting member 1 is hit, and the cylindrical body 11 is elastically deformed and inserted into the counterbore part 41 of the mounting hole 4. The plate-like part 12 is brought into contact with the guide rail 3. As a result, the cylindrical body 11 of the cover mounting member 1 is locked to the counterbore part 41 of the mounting hole 4 at the tightening margin, and the plate-like part 12 is arranged in contact with the upper surface of the guide rail 3. In this way, the cover attachment member 1 is attached to the upper surface of the guide rail 3. FIG. 4B shows this state.

次に、案内レール３の上面に取り付けられたカバー取付部材１の上に、カバー２を置いて上から押しつけることで、カバー取付部材１の上にカバー２を被せる。その際に、カバー取付部材１の板状部１２の斜面１２ａにカバー２の側面部２２の斜面が係合するため、カバー２がカバー取付部材１から外れにくくなる。このようにして、カバー２がカバー取付部材１を介して、案内レール３の上面に取り付けられる。図４（ｃ）は、この状態を示す。また、図５は、この状態を示す斜視図である。   Next, the cover 2 is placed on the cover mounting member 1 by placing the cover 2 on the cover mounting member 1 mounted on the upper surface of the guide rail 3 and pressing it from above. At that time, the slope of the side surface portion 22 of the cover 2 is engaged with the slope 12 a of the plate-like portion 12 of the cover mounting member 1. In this way, the cover 2 is attached to the upper surface of the guide rail 3 via the cover attachment member 1. FIG. 4C shows this state. FIG. 5 is a perspective view showing this state.

長尺なカバー２を取り付ける際には、図３に示すように、板状部１１の長さがカバー２の長さより短いカバー取付部材１を、カバー２の長さに合わせた個数だけ用意する。これにより、円柱体（取付穴係合部）１１の案内レール３の取付穴４に対する位置精度を厳しくしなくても、カバー取付部材１を介してカバー２を案内レール３の上面に容易に取り付けることができる。   When attaching the long cover 2, as shown in FIG. 3, as many cover attachment members 1 as the plate-like portions 11 are shorter than the cover 2 are prepared according to the length of the cover 2. . Accordingly, the cover 2 can be easily attached to the upper surface of the guide rail 3 via the cover attachment member 1 without strict positioning accuracy of the cylindrical body (attachment hole engaging portion) 11 with respect to the attachment hole 4 of the guide rail 3. be able to.

ここで、図６に示すように、カバー取付部材１の板状部１２に、円柱体１１の外周を縁取る凹部（案内レール３の上面と接触しない逃げ部）１３を設けると、合成樹脂製の円柱体１１の外周部が取付穴４の金属面に押しつけられて削られたものが、凹部１３に溜まるため、カバー取付部材１の板状部１１と案内レール３の上面との間に削りかすが入ることを防止できる。   Here, as shown in FIG. 6, when the plate-like portion 12 of the cover mounting member 1 is provided with a recess (a relief portion that does not contact the upper surface of the guide rail 3) 13 that borders the outer periphery of the cylindrical body 11, Since the outer peripheral portion of the cylindrical body 11 is pressed against the metal surface of the mounting hole 4 and scraped off is accumulated in the recess 13, it is scraped between the plate-like portion 11 of the cover mounting member 1 and the upper surface of the guide rail 3. It is possible to prevent debris from entering.
