Description

【０００１】
【発明の属する技術分野】
本発明は、工作機械において、移動体を案内するレールの摺動面を研削する装置に関するものである。
【０００２】
【従来の技術】
図３に示すように、例えば旋盤のスラントベッド１には、上側のサドル２及び下側サドル３を案内する４本のレール４が設けられている。レール４の摺動面が切粉のかみ込みで損傷したり長期使用に伴い偏摩耗したりした場合、従来は、ベッド１からサドル２，３を取り外し、ベッド１を研削盤に運び込んで、レール４の摺動面を研削していた。このため、修復作業が大掛かりとなり、旋盤を長時間稼動できなくなるという問題点があった。
【０００３】
【発明が解決しようとする課題】
そこで、本発明の課題は、機械を分解したり移動したりする必要がなく、レールの摺動面を短時間に修復することができる摺動面研削装置を提供することにある。
【０００４】
【課題を解決するための手段】
上記課題を解決するために、請求項１の発明は、顎部を有するレールがベッド上を所定方向へ延設されており、当該レールに移動体を案内させる工作機械において、前記レールの摺動面の一つとなる顎部裏面を研削するための摺動面研削装置であって、前記顎部裏面を研削する砥石と、当該砥石を駆動するモータと、前記砥石及びモータを保持するホルダーと、前記ホルダーが固定されると共に前記レールの顎部裏面以外の摺動面を挟持する挟持部が設けられており、前記顎部裏面以外の摺動面に沿って摺動可能に取り付けられる取付部材とを備える一方、前記ホルダーの前記取付部材への固定位置を調整することによって、前記砥石の前記顎部裏面への切込み量を調整可能とした切込み機構を設けたことを特徴とする。
【０００５】
請求項２の発明による摺動面研削装置は、取付部材を移動体に連結する連結部材を備え、移動体を利用して砥石を摺動面の長手方向へ自動送りできるように構成される。
【０００７】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。図１は旋盤のスラントベッド１に設けられたレール４の摺動面を研削する装置を例示するものである。この摺動面研削装置は、下側のサドル３（図３参照）を案内するレール４の摺動面のうち損傷した顎部の摺動面４ａを研削する円筒形の砥石５と、砥石５を駆動するエアモータ６と、砥石５及びエアモータ６を保持するホルダー７と、ホルダー７をレール４に摺動可能に取り付ける取付部材８と、砥石５を摺動面４ａと直角方向に位置調整する切込み機構９とから構成されている。１０は砥石軸である。
【０００８】
取付部材８にはレール４を挟持する挟持部８ａが設けられ、損傷していない３つの摺動面４ｂ，４ｃ，４ｄに沿って砥石５を高い直進度で案内できるようになっている。切込み機構９は、取付部材８に対しホルダー７を摺動面４ａと直角方向に案内するアリ及びアリ溝からなるスライドガイド１１と、このガイド１１に沿ってホルダー７をスライドさせるボルト１２とを備え、摺動面４ａに対する砥石５の切込み量を調整できるように構成されている。また、取付部材８にはく字型の補助プレート１３が固定され、その下端を下側のレール４で案内することにより、摺動面４ａに対する砥石軸１０の傾斜を防止できるようになっている。
【０００９】
また、図２に示す摺動面研削装置は、図１の装置と同様に機能する砥石５、エアモータ６、ホルダー７、取付部材８及び切込み機構９に加え、取付部材８を上側のサドル２に連結する連結部材１４と、取付部材８をレール４に押し付けるばね１５とを備え、サドル２を利用して砥石５を摺動面４ａの長手方向に自動送りできるように構成されている。ばね１５は上側のサドル２に固定されたアーム１６の先端に設けられ、取付部材８をレール４の摺動面４ｃに圧接させて、装置の浮き上がりを防止する。
【００１０】
上記構成の研削装置を用いて摺動面４ａを修復する際には、ボルト１２を回して砥石５の切込み量を調整したのち、取付部材８の挟持部８ａをレール４に嵌合し、砥石５を摺動面４ａに当て、エアモータ６を起動して砥石５を回転させ、取付部材８を手で押さえながら摺動面４ｂ，４ｃ，４ｄに沿って移動し、砥石５で摺動面４ａを研削する。こうすれば、サドル２，３をベッド１から取り外したり、ベッド１を移動したりする必要がなく、小型の研削装置をレール４に沿って送るだけの簡易な作業で摺動面４ａを短時間に修復することができる。また、図２の研削装置の場合は、砥石５を摺動面４ａの長手方向に自動送りできて、修復作業をより簡単に行うことができる。
【００１１】
なお、本発明は上記実施形態に限定されるものではなく、例えば、エアモータ６にかえて電動モータを用いたり、旋盤以外の工作機械の摺動面研削装置に適用したりするなど、本発明の趣旨を逸脱しない範囲で各部の形状並びに構成を適宜に変更して実施することも可能である。
【００１２】
【発明の効果】
以上詳述したように、本発明の請求項１記載の摺動面研削装置によれば、砥石及びモータを保持するホルダーと、ホルダーが固定され、レールに摺動可能に取り付けられる取付部材とを備えているため、機械を分解したり移動したりする必要がなく、レールの顎部裏面を短時間に修復できるという優れた効果を奏する。また、取付部材にレールの顎部裏面以外の摺動面を挟持する挟持部を設け、レールへ取り付けた際に顎部裏面以外の摺動面に沿って摺動可能としているため、砥石を高い直進度で案内できるので、一層高精度な修復作業が可能となる。さらに、ホルダーの取付部材への固定位置を調整することによって、砥石の顎部裏面への切込み量を調整可能とした切込み機構を設けているため、顎部裏面を修復する際に砥石の切込み量を調整することができる。
【００１３】
また、本発明の請求項２記載の摺動面研削装置によれば、工作機械などの既存の移動体を用いて砥石をレールの摺動面に沿って自動送りすることができ、より簡単に修復作業を行うことができるという効果を奏する。
