の摺動を許容して係合している。A gate-shaped column b horizontally supports a cross rail C so as to be vertically movable, and a spindle head e equipped with a processing grindstone d engages with the cross rail C to allow sliding in the left and right direction.
チャックを介して被削物を載置するテーブルｆは、クロ
スレールＣの直交方向に摺動可能にベッドａの中央部に
載置されている。A table f, on which a workpiece is placed via a chuck, is placed in the center of the bed a so as to be slidable in a direction orthogonal to the cross rail C.
そして、クロスレールＣの昇降動、主軸頭ｅの左右運動
及びテーブルｆの前後運動の各運動により、加工砥石ｄ
の位置決めを行っている。Then, due to the vertical movement of the cross rail C, the left-right movement of the spindle head e, and the back-and-forth movement of the table f, the processing grindstone d
is being positioned.

ラム前後動タイプや、サドルとサドルに載置したテーブ
ルで前後及び左右方向の位置決めを行うサドルタイプが
知られている。In addition, other types of surface grinders include a column type that moves back and forth, in which a column equipped with a grindstone that can be raised and lowered slides back and forth on the bed, and a saddle and a table placed on the saddle that allows for positioning in the front and back and left and right directions. There are known saddle types that do this.
〈本発明が解決しようとする問題点〉 従来の平面研削盤には次のような問題点がある。<Problems to be solved by the present invention> Conventional surface grinders have the following problems.
〈イ〉前述した門形の平面研削盤にあっては、クロスレ
ールＣ上における主軸頭ｅの位置によって、クロスレー
ルＣの撓み量が変化する。<A> In the above-mentioned gate-shaped surface grinder, the amount of deflection of the crossrail C changes depending on the position of the spindle head e on the crossrail C.
クロスレールＣの撓み量の変化に伴い、加工砥石ｄの加
工面の位置決めが上下方向にずれるため、加工精度が低
い。As the amount of deflection of the cross rail C changes, the positioning of the processing surface of the processing grindstone d shifts in the vertical direction, resulting in low processing accuracy.
〈口〉コラム前後動タイプにあっては、コラムの僅かな
傾きが原因でコラム摺動方向に位置決め誤差を生じる不
都合がある。<Exposure> The back-and-forth column type has the disadvantage that a slight inclination of the column causes positioning errors in the sliding direction of the column.

トロークが大きい場合や、被削物の載置位置か不適切で
あると、これらの各部材の重心の関係がアンバランスに
なり易（、その結果高い加工精度を得難いといった問題
点がある。For saddle type models, if the stroke of the saddle or table is large, or if the workpiece is placed in an inappropriate position, the relationship between the centers of gravity of these parts tends to become unbalanced. As a result, there is a problem that it is difficult to obtain high processing accuracy.

６０は主軸頭で、門形コラム５０の横架部５３に接続し
ている。Reference numeral 60 denotes a spindle head, which is connected to the horizontal frame portion 53 of the portal column 50.
７０は主軸頭６０に支持された加工砥石で、主軸頭６０
の昇降運動又は加工砥石７０の昇降運動によって昇降可
能に設けら〜れている。70 is a processing grindstone supported by the spindle head 60;
It is provided so that it can be raised and lowered by the raising and lowering movement of the processing grindstone 70 or by the raising and lowering movement of the processing grindstone 70.
従って、前後方向の位置決めをテーブル２０の前後動に

動面８０を、被削物４０上面の加工面とほぼ同一平面上
に位置するように構成する。<Expo> Formation position of column sliding surface In the present invention, as shown in FIG. It is configured to be located on substantially the same plane as the processing surface of the upper surface of the workpiece 40.
即ち、テーブル２０を挟んで両側に位置する両組のコラ
ム摺動面８０．８０が、被削物４０の加工面とほぼ一致
するように構成する。That is, the two sets of column sliding surfaces 80, 80 located on both sides of the table 20 are configured to substantially coincide with the machined surface of the workpiece 40.

It is recommended to position 80.
コラム摺動面８０の形成位置を上記のように限定したの
は、加工精度の向上を図るためである。The reason why the formation position of the column sliding surface 80 is limited as described above is to improve processing accuracy.
〈作用〉
次に第２図を基に門形平面研削盤の作用について説明す
る。<Function> Next, the function of the portal surface grinder will be explained based on FIG.
〈イ〉加工準備
チャック３０に被削物ｔ−４０を据え付け、加工砥石７
０を駆動する。<A> Install the workpiece t-40 on the machining preparation chuck 30, and set the machining grindstone 7
Drive 0.
〈口〉位置決め
第２図において門形コラム５０の摺動により左右方向の
位置決めを行い、テーブル２０の摺動により前後方向の
位置決めを行い、そして加工砥石７０の昇降により上下
方向の位置決めを夫々行って、所定の研削を行う。<Open> Positioning In FIG. 2, positioning is performed in the left and right directions by sliding the portal column 50, positioning is performed in the front and back direction by sliding the table 20, and positioning is performed in the vertical direction by raising and lowering the processing grindstone 70. Then, perform the specified grinding.
本発明の門形平面研削盤は、コラム摺動面８０．８０が
被削物４０の加工面を通る平面上にほぼ一致しているか
ら、高精度の加工を行える。The portal surface grinder of the present invention can perform highly accurate machining because the column sliding surfaces 80, 80 substantially coincide with the plane passing through the machining surface of the workpiece 40.
ところで、門形コラム５０のコラム摺動面８０がテーブ
ル２０を跨いで両側に位置する関係から、従来のコラム
前後動タイプのような片持梁構造による傾きが生じ難い
。By the way, since the column sliding surfaces 80 of the gate-shaped column 50 are located on both sides of the table 20, it is difficult to cause inclination due to the cantilever structure as in the conventional type of column that moves back and forth.
また、門形コラム５０を構成する横架部５３の途上に撓
みが生じた場合を想定しても、加工砥石７０を固着した
門形コラム５０が摺動するから、加工砥石７０の移動軌
跡は、常に同一水平線上に位置することになる。Furthermore, even if it is assumed that the horizontal frame 53 constituting the gate-shaped column 50 is bent, the movement trajectory of the processing grindstone 70 will be , will always be located on the same horizontal line.
このように横架部５３が撓んだとしても、被削物４０と
加工砥石７０の距離を一定に保てるから、横架部５３に
撓みを生じても加工精度が低下することはない。Even if the horizontal frame part 53 is bent in this way, the distance between the workpiece 40 and the processing grindstone 70 can be kept constant, so even if the horizontal frame part 53 is bent, the machining accuracy will not deteriorate.
〈その他の実施例〉
前述した実施例は加工砥石の支軸を横向きに配設した場
合について説明したが、縦向きタイプであっても勿論構
わない。<Other Embodiments> In the above-mentioned embodiments, a case has been described in which the spindle of the processing grindstone is arranged horizontally, but it is of course possible to use a vertically oriented type.
また、本発明は非可動構造の門形コラムを装備した公知
の例えばプレーナーや治具ポーラ−又は門形フライス盤
等に適用できることは勿論である。It goes without saying that the present invention can be applied to known planers, jig polars, portal milling machines, etc., which are equipped with a non-movable portal column.
〈本発明の効果〉
本発明は以上説明したようになるから次の効果が得られ
る。<Effects of the Present Invention> Since the present invention is as described above, the following effects can be obtained.
〈イ〉本発明は単に従来固定式であった門形コラムを可
動式に構成しただけではなく、コラム摺動面を被削物の
加工面を通る同一水平面上に位置するように構成した。(A) The present invention not only makes the conventionally fixed gate-shaped column movable, but also configures the column sliding surface to be located on the same horizontal plane passing through the machined surface of the workpiece.
これにより従来機に比べて著しく加工精度の向上が図れ
る。This significantly improves machining accuracy compared to conventional machines.
〈口〉従来の門形の平面研削盤は、門形コラムを横架す
る横架部材に撓みを生じると、この撓みが位置決め誤差
の原因になっていた。<Exposure> In conventional portal-shaped surface grinders, if the horizontal member that horizontally spans the portal column is deflected, this deflection causes positioning errors.
本発明の場合、門形コラムを構成する横架部材が仮に撓
んだとしても、この撓みが位置決め誤差の原因にならず
、安定した高精度を持続できる。In the case of the present invention, even if the horizontal member constituting the portal column is bent, this bending does not cause a positioning error, and stable high precision can be maintained.
〈ハ〉従来のコラム前後動タイプにあっては、コラムが
加工砥石の支軸方向に傾き易く加工誤差を生じ易い不都
合がある。<C> The conventional type of column that moves back and forth has the disadvantage that the column tends to tilt in the direction of the spindle of the processing grindstone, which tends to cause processing errors.
これに対し、本発明はコラムがテーブルを跨いで摺動す
るから、コラムが加工砥石の支軸方向に傾きを起こし難
（、従来のような不都合がおきない。In contrast, in the present invention, since the column slides across the table, the column is less likely to tilt in the direction of the spindle of the processing grindstone (unlike the conventional method).
〈二〉従来のサドルタイプは、テーブルとサドルのスト
ロークにより各部材の重心がアンバランスになり易い欠
点があった。(2) The conventional saddle type has the disadvantage that the center of gravity of each member tends to be unbalanced due to the stroke of the table and the saddle.
本発明においては、テーブルと門形コラムが独立して摺
動するから、従来のような面精度にピッチ誤差を生じな
い。In the present invention, since the table and the gate-shaped column slide independently, there is no pitch error in the surface accuracy as in the prior art.
〈ホ〉各種平面加工の精密仕上げ用途に好適である。<E> Suitable for precision finishing applications in various plane processing.
