Description

本発明は、給油継手部品を備えたリニアガイド装置に関するものである。   The present invention relates to a linear guide device including an oil supply joint component.

従来より、エンドキャップ上面からテーブルを介して給油するとき，エンドキャップ上面とテーブルの間にスキマが空く場合に，そのスキマを埋めて潤滑剤供給の通路を形成するために、給油継手部品を用いなければならず、この給油継手部品をエンドキャップに固定する時の作業がしにくい等の課題があった。   Conventionally, when refueling from the top surface of the end cap through the table, if there is a gap between the top surface of the end cap and the table, a lubrication joint component has been used to fill the clearance and form a lubricant supply passage. There has been a problem that it is difficult to perform the operation when fixing the oil supply joint component to the end cap.

この部分の改善の先行技術としては、図６に示す給油継手部品を備えたリニアガイド装置（特開２００８−２６７５９１号公報）がある。リニアガイド装置は、案内レール４とスライダ５と複数個の転動体（不図示）とを備えている。案内レール４およびスライダ５は、互いに対向配置されて転動体の転動通路（不図示）を形成する転動溝（転動体が「ころ」の場合には転動面）を有する。スライダ５は、さらに、転動体の戻し通路（不図示）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（不図示）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が循環することにより、案内レール４およびスライダ５の一方が他方に対して相対的に直線運動する。   As a prior art for improving this portion, there is a linear guide device (Japanese Patent Laid-Open No. 2008-267591) having an oil supply joint part shown in FIG. The linear guide device includes a guide rail 4, a slider 5, and a plurality of rolling elements (not shown). The guide rail 4 and the slider 5 have rolling grooves (a rolling surface when the rolling elements are “rollers”) that are arranged to face each other and form a rolling passage (not shown) of the rolling elements. The slider 5 further includes a return path (not shown) for the rolling elements and a direction changing path (not shown) for communicating the return path and the rolling path. The rolling path, the return path, and the direction changing path constitute a circulation path of the rolling element, and the rolling element circulates in the circulation path so that one of the guide rail 4 and the slider 5 is in relation to the other. Move relatively linearly.

このようなリニアガイド装置のスライダ５においては、スライダ本体３の直動方向端部にエンドキャップ２が固定されている。エンドキャップ２は、案内レール４の幅方向両側に配置される脚部２３と、両脚部と直交する方向に延びて両脚部を連結する胴部２１とからなる。そして、両脚部のスライダ本体側の面に、転動体の方向転換路の外側溝（不図示）が形成され、胴部２１には給油口（不図示）が形成されている。また、エンドキャップ２には、前記給油口から前記方向転換路に向かう油路（不図示）が形成されている。スライダ本体３の上面がスライダ５の上に取り付けるテーブル（不図示）の取り付け面となる。   In the slider 5 of such a linear guide device, the end cap 2 is fixed to the linear movement direction end of the slider body 3. The end cap 2 includes leg portions 23 disposed on both sides of the guide rail 4 in the width direction, and a trunk portion 21 that extends in a direction orthogonal to the both leg portions and connects the both leg portions. And the outer side groove | channel (not shown) of the direction change path of a rolling element is formed in the surface at the side of the slider main body of both leg parts, and the oil filler opening (not shown) is formed in the trunk | drum 21. FIG. Further, the end cap 2 is formed with an oil passage (not shown) from the oil filler port toward the direction change passage. The upper surface of the slider body 3 serves as a mounting surface for a table (not shown) that is mounted on the slider 5.

従来より、スライダ５の上に取り付けるテーブル内に油路を設け、この油路を通してエンドキャップ２に給油することが行われている。その際に、エンドキャップ２の上面がスライダ本体３の上面より低く形成されている場合には、例えば図６及び図７に示すように、エンドキャップ２の胴部２１の上面に設けた給油口２２の上に、ほぼ円柱体からなるブロック状の給油継手部品１００を取り付けている。   Conventionally, an oil passage is provided in a table attached on the slider 5 and the end cap 2 is supplied with oil through the oil passage. At that time, when the upper surface of the end cap 2 is formed lower than the upper surface of the slider body 3, for example, as shown in FIGS. 6 and 7, the oil filler opening provided on the upper surface of the body portion 21 of the end cap 2 is used. On block 22, a block-shaped oil supply joint component 100 made of a substantially cylindrical body is attached.

図７に示すように、給油継手部品１００の円板状の下端突出部１０１に、エンドキャップ２の給油口２２に連通する給油口１０１ａが形成されている。また、エンドキャップ２の給油口２２の上に、給油継手部品１００の下端突出部１０１が遊嵌される円形の凹部２３０が形成されている。この凹部２３０に、給油継手部品１００の下端突出部１０１が嵌合されている。   As shown in FIG. 7, an oil supply port 101 a communicating with the oil supply port 22 of the end cap 2 is formed in the disc-like lower end protruding portion 101 of the oil supply joint component 100. Further, a circular recess 230 into which the lower end protruding portion 101 of the oil supply joint component 100 is loosely fitted is formed on the oil supply port 22 of the end cap 2. The lower end protruding portion 101 of the oil supply joint component 100 is fitted into the recess 230.

しかしながら、この先行技術には、エンドキャップ２の凹部２３０の内周面に更に凹部を設けなければならないという問題がある。一般にエンドキャップ２は樹脂の射出成形で形成されるが，射出成形する場合には，この内周面の凹部で金型が抜けなくなってしまう。金型を無理に抜くことは出来るが，この場合はエンドキャップ内周面の凹部の形状が崩れるので，給油継手部品１００の下端突出部１０１が凹部２３０とぴったりと嵌合せず、潤滑油が漏れやすくなるという問題があった。   However, this prior art has a problem that a further recess must be provided on the inner peripheral surface of the recess 230 of the end cap 2. In general, the end cap 2 is formed by resin injection molding. However, in the case of injection molding, the mold cannot be removed by the concave portion of the inner peripheral surface. Although the mold can be forcibly pulled out, in this case, the shape of the concave portion on the inner peripheral surface of the end cap collapses, so that the lower end protruding portion 101 of the oil supply joint component 100 does not fit exactly into the concave portion 230 and the lubricating oil leaks There was a problem that it became easier.

以下、本発明の実施形態について説明する。
図１は、第１実施形態の給油継手部品１を示す平面図（ａ）と正面図（ｂ）である。この給油継手部品１は、ほぼ直方体状の本体部１１と、凸部としての円柱状の突起１２と、からなり、中心に油路１３が形成されている。本体部１１の上面には、スライダ本体の上面に固定されるテーブルに設けられた油路（不図示）と連結する部分に配設される油漏れ防止部材としてのＯリングを嵌める凹所１１ａが形成されている。この給油継手部品１は、エンドキャップ２と同じ材料、例えばＰＯＭなどの合成樹脂を用いた射出成形法で得ることができる。 Hereinafter, embodiments of the present invention will be described.
Drawing 1 is a top view (a) and a front view (b) showing oil supply joint component 1 of a 1st embodiment. This oil supply joint component 1 is composed of a substantially rectangular parallelepiped body portion 11 and a columnar projection 12 as a convex portion, and an oil passage 13 is formed at the center. On the upper surface of the main body 11, there is a recess 11 a for fitting an O-ring as an oil leakage preventing member disposed at a portion connected to an oil passage (not shown) provided on a table fixed to the upper surface of the slider main body. Is formed. This oil supply joint component 1 can be obtained by an injection molding method using the same material as the end cap 2, for example, a synthetic resin such as POM.

図２は、エンドキャップ２を示す平面図（ａ）と正面図（ｂ）である。エンドキャップ２の胴部２１の上面中心には給油継手部品１の油路１３と連通する給油口２２が形成されている。この給油口２２は、エンドキャップ２のスライダ本体３側の面に形成された、方向転換路に向かう油路と接続されている。給油口２２の周囲にＯリングを嵌める凹所１１ｂが形成されている。また胴部２１の上面には給油継手部品１の突起１２と対応する位置に直径が突起１２の直径よりも多少小さい穴１５が形成されている。穴１５は、突起１２と軽い締まりばめをする様になっていれば良く、突起１２は穴１５と締まりばめにて給油継手部品１をエンドキャップ２に固定することが出来れば、どの様な断面形状であっても良い。   FIG. 2 is a plan view (a) and a front view (b) showing the end cap 2. An oil supply port 22 communicating with the oil passage 13 of the oil supply joint component 1 is formed at the center of the upper surface of the body portion 21 of the end cap 2. The oil supply port 22 is connected to an oil passage that is formed on the surface of the end cap 2 on the slider body 3 side and that faces the direction change passage. A recess 11b for fitting an O-ring around the oil filler port 22 is formed. A hole 15 having a diameter slightly smaller than the diameter of the protrusion 12 is formed on the upper surface of the body portion 21 at a position corresponding to the protrusion 12 of the fuel filler joint component 1. The hole 15 only needs to have a light interference fit with the protrusion 12, and the protrusion 12 can be fixed to the end cap 2 with the hole 15 and the interference fit. Any cross-sectional shape may be used.

図３は、給油継手部品１をエンドキャップ２に取り付けた状態の図である。給油継手部品１をエンドキャップ２に取り付けるには、まず、エンドキャップ２の凹所１１ｂにＯリング１６を嵌め込み、次に給油継手部品１の突起１２をエンドキャップ２の穴１５に合せ、嵌入することによって行われる。

図４は第２実施形態の給油継手部品７を示す正面図であり、図５は第２実施形態の給油継手部品７をエンドキャップ２に取り付けた状態の図である。第２実施形態の給油継手部品７は第１の実施形態の給油継手部品１の突起１２の代わりに凹部としての穴１７とした点が異なる。第２実施形態のエンドキャップ２は第１の実施形態のエンドキャップ２と同じものである。   FIG. 4 is a front view showing the oil supply joint component 7 of the second embodiment, and FIG. 5 is a view showing a state where the oil supply joint component 7 of the second embodiment is attached to the end cap 2. The oil supply joint component 7 of the second embodiment is different in that it is a hole 17 as a recess instead of the protrusion 12 of the oil supply joint component 1 of the first embodiment. The end cap 2 of the second embodiment is the same as the end cap 2 of the first embodiment.

給油継手部品７をエンドキャップ２に取り付けるには、まず、エンドキャップ２の凹所１１ｂにＯリング１６を嵌め込み、次にエンドキャップ２の２箇所の穴１５にピン１８を圧入する。このピン１８の直径は穴１５及び給油継手部品７の穴１７の直径よりも多少大きくなっている。そしてこの２箇所のピン１８の位置に給油継手部品７の穴１７を合せ給油継手部品７押し込むことによって、給油継手部品７がエンドキャップ２に固定される。ピン１８は、穴１５及び穴１７と締まりばめによって給油継手部品７をエンドキャップ２に固定することが出来れば、どの様な断面形状であっても良く、スプリングピン等を用いても良い。
この第２の実施形態の給油継手部品を備えたリニアガイド装置によっても、簡単な構造で給油継手部品がエンドキャップに確実に固定されて、潤滑油が漏れることがない。 In order to attach the oil supply joint component 7 to the end cap 2, first, the O-ring 16 is fitted into the recess 11 b of the end cap 2, and then the pins 18 are press-fitted into the two holes 15 of the end cap 2. The diameter of the pin 18 is slightly larger than the diameter of the hole 15 and the hole 17 of the oil supply joint component 7. The oil supply joint part 7 is fixed to the end cap 2 by aligning the holes 17 of the oil supply joint part 7 with the positions of the two pins 18 and pushing in the oil supply joint part 7. The pin 18 may have any cross-sectional shape as long as the oil supply joint component 7 can be fixed to the end cap 2 by an interference fit with the holes 15 and 17, and a spring pin or the like may be used.
Also with the linear guide device provided with the oil supply joint part of the second embodiment, the oil supply joint part is securely fixed to the end cap with a simple structure, and the lubricating oil does not leak.

なお、第２実施形態の説明において、まずエンドキャップ２の２箇所の穴１５にピン１８を圧入した後に給油継手部品７の穴１７をそのピン１８の位置に合わせて給油継手部品７を押し込んでエンドキャップ２に固定する例を示したが、まず、ピン１８を給油継手部品７の穴１７に圧入し、この給油継手部品７に圧入されたピン１８をエンドキャップ２の穴１５に圧入して、給油継手部品７をエンドキャップ２に固定しても良い。
また、突起１２と穴１５が締まりばめする構造を示したが、必ずしも締まりばめでなくとも、例えば穴が奥側で広がる様な構造としておき、突起も先端で広がる構造として、突起先端の広がりが穴の中で引っ掛かる構造としても良い。例えば、エンドキャップ２の穴１５が、エンドキャップ２の肉盗みと貫通できるような場合には、このような構造でも良い。 In the description of the second embodiment, first, after the pins 18 are press-fitted into the two holes 15 of the end cap 2, the hole 17 of the oil supply joint part 7 is aligned with the position of the pin 18 and the oil supply joint part 7 is pushed in. Although an example of fixing to the end cap 2 has been shown, first, the pin 18 is press-fitted into the hole 17 of the oil filler joint part 7, and the pin 18 press-fitted into the oil filler joint part 7 is press-fitted into the hole 15 of the end cap 2. The oil supply joint component 7 may be fixed to the end cap 2.
In addition, the structure in which the protrusion 12 and the hole 15 are interference-fitted is shown. However, even if it is not necessarily an interference-fitting, for example, a structure in which the hole is widened on the back side is set, and the protrusion is also widened on the tip, so It is good also as a structure which catches in a hole. For example, such a structure may be used when the hole 15 of the end cap 2 can penetrate the meat of the end cap 2.
