Description

この発明は、研削盤に関する。   The present invention relates to a grinding machine.

従来、研削盤としては、図４に示すように、円筒状ワークＷの内外両面を研削する砥石31と、砥石31を研削位置とこれよりも奥側のドレッシング位置の間で移動させる移動手段（図示略）と、ドレッシング位置で砥石31の外周面をドレッシングするドレッサ32とを備えている。ドレッサ32は、内外面研削用ドレッシング工具41と、ドレッシング工具41をその先端が手前側に向けるように保持するホルダ42とよりなるものが知られている（例えば、特許文献１参照。）。   Conventionally, as a grinding machine, as shown in FIG. 4, a grindstone 31 that grinds both the inner and outer surfaces of a cylindrical workpiece W, and a moving means that moves the grindstone 31 between a grinding position and a dressing position on the far side of this ( (Not shown) and a dresser 32 for dressing the outer peripheral surface of the grindstone 31 at the dressing position. The dresser 32 is known to be composed of a dressing tool 41 for inner and outer surface grinding and a holder 42 for holding the dressing tool 41 so that the tip thereof is directed to the front side (see, for example, Patent Document 1).

図４において、内面研削位置がＧ１で、外面研削位置がＧ２でそれぞれ示されている。また、ドレッシング位置がＤで示されている。   In FIG. 4, the inner surface grinding position is indicated by G1, and the outer surface grinding position is indicated by G2. The dressing position is indicated by D.

ドレッシングに際しては、砥石31にドレッシング工具41を一方の側、すなわち、研削盤奥側から当てた状態で行われる。ドレッシングの終了後、ワークＷの研削を行うに際しては、砥石31のドレッシングの行われた奥側をワークＷの研削すべき内面または外面に手前側から当てられる。ワーク内面を研削する場合、ドレッシング位置Ｄから内面研削位置Ｇ１まで移動させるストロークＳ１は比較的小さいけれど、ワーク外面を研削する場合、ドレッシング位置Ｄから外面研削位置Ｇ２までは、ワークＷを直径方向にまたいで移動させる必要があり、そのストロークＳ２は相当に大きいものであった。そのため、研削盤の構造が大きくなり勝ちであった。
特開２０００−２１８５２７号公報 Dressing is performed in a state where the dressing tool 41 is applied to the grindstone 31 from one side, that is, from the back side of the grinding machine. When the workpiece W is ground after the dressing is completed, the back side of the grindstone 31 where the dressing is performed is applied to the inner surface or the outer surface of the workpiece W to be ground from the front side. When grinding the workpiece inner surface, the stroke S1 for moving from the dressing position D to the inner grinding position G1 is relatively small. However, when grinding the workpiece outer surface, the workpiece W is moved in the diameter direction from the dressing position D to the outer grinding position G2. Further, it was necessary to move it, and the stroke S2 was considerably large. For this reason, the structure of the grinding machine has become large, and it has been a win.
JP 2000-218527 A

この発明の目的は、砥石のドレッシングが終了した後、砥石をドレッシング位置から研削位置まで移動させる距離を小さくすることができ、もって、構造を小さくすることのできる研削盤を提供することにある。   An object of the present invention is to provide a grinding machine that can reduce the distance by which the grindstone is moved from the dressing position to the grinding position after dressing of the grindstone is completed, and thus can reduce the structure.

この発明による研削盤は、円筒状ワークの内外両面を研削する砥石と、砥石を研削位置とこれよりも奥側のドレッシング位置の間で移動させる移動手段と、ドレッシング位置で砥石の外周面をドレッシングするドレッサとを備えている研削盤において、ドレッシング位置が、内面研削用ドレッシング位置およびこれよりも奥側の外面研削用ドレッシング位置よりなり、ドレッサが、内面研削用ドレッシング工具および外面研削用ドレッシング工具と、両ドレッシング工具をそれぞれの先端が反対方向に向けるように保持するホルダと、進入時のホルダの内面研削用ドレッシング工具の先端が手前側に向けられるとともに、外面研削用ドレッシング工具の先端が奥側に向けられるよう内面研削用ドレッシング位置および外面研削用ドレッシング位置間に対しホルダを進退させる進退手段とを備えていることを特徴とするものである。   The grinding machine according to the present invention includes a grinding wheel for grinding both inner and outer surfaces of a cylindrical workpiece, a moving means for moving the grinding wheel between a grinding position and a dressing position on the back side, and dressing the outer peripheral surface of the grinding wheel at the dressing position. A dressing position comprising an internal grinding dressing position and an external grinding dressing position on the inner side, and the dresser includes an internal grinding dressing tool and an external grinding dressing tool. , The holder that holds both dressing tools so that their tips are directed in opposite directions, and the tip of the dressing tool for internal grinding of the holder at the time of entry is directed to the near side, and the tip of the dressing tool for external grinding is on the back side Dressing position for internal grinding and dressing for external grinding so that It is characterized in that a moving means for advancing and retracting the holder to 置間.

この発明による研削盤では、ワーク内面を研削する場合、ワーク内面に手前側から砥石が当てられ、ワーク外面を研削する場合、ワーク外面に奥側から砥石が当てられる。とくに、ワーク外面を研削する場合に、ワーク外面に奥側から砥石が当てられることより、ドレッシング位置から研削位置まで砥石を移動させる距離を極めて小さくすることができる。したがって、研削盤の構造を小さくすることが可能である。   In the grinding machine according to the present invention, when the work inner surface is ground, a grindstone is applied to the work inner surface from the front side, and when the work outer surface is ground, the grindstone is applied to the work outer surface from the back side. In particular, when grinding the workpiece outer surface, the grinding stone is applied to the workpiece outer surface from the back side, so that the distance for moving the grinding wheel from the dressing position to the grinding position can be made extremely small. Therefore, it is possible to reduce the structure of the grinding machine.

この発明によれば、砥石のドレッシングが終了した後、砥石をドレッシング位置から研削位置まで移動させる距離を小さくすることができ、もって、構造を小さくすることのできる研削盤が提供される。   According to this invention, after the dressing of the grindstone is completed, the distance by which the grindstone is moved from the dressing position to the grinding position can be reduced, thereby providing a grinding machine capable of reducing the structure.
