Description

【0001】
【考案の属する技術分野】
本来、工作機械による加工は、X・Y・Z軸の3方向とも、仕様書に記載されている固有のストロークを超える加工は不可能である。しかし、実際の作業者にとって、あとほんの少しストロークを延長出来れば・・・と思うことはしばしばである。本考案は、そのような場合に対応するべく考えられたものである。
【0002】
【従来の技術】
従来、仕様上のストロークよりも長い寸法の加工を行うには、更に大型の工作機械を導入するか、もしくは他への外注に頼るしか方法がなかったが、何れにしても、夛大の費用を必要とするし、納期の制約に対応出来ない場合が多い。そこで、被加工物を所定のストロークの範囲内で、出来るだけの加工を行い、被加工物を振り替えて逆方向から残った部分を再加工するという方法をとる。しかし、この方法では、被加工物をいったんバイスから取り外して、くわえ直す必要があるので、加工のつなぎ目附近に段差が出来るのを避けられず、従って、高精度の加工にはとうてい耐えられないという、いわば工作機械としては致命的な欠陥があった。
【0003】
【考案の実施の形態】
本考案の実施状態を図面に従って詳述する。
【図1】本考案の微速度送り機構▲1▼とバイス▲2▼(図では3連)である。バイスのハンドル▲3▼に連結するスクリューネジ▲4▼によってクランプ▲5▼が被加工物(ワーク)をしっかり固定する。バイスは、スライドウェイ▲6▼にリードされて、正確な平行度を保ちながら、送りネジ▲7▼と低速ギャドモーター▲8▼により駆動され、スライドウェイ上を移動する。▲9▼は全体を工作機械のテーブルに固定するためのボルト穴である。
【図2】本考案による微速度送り機構を具備するバイスを、典型的な平削り型工作機械(フライス盤・平面研削盤等)に取り付けた状態を示す。
ベース▲10▼の上に乗ったサドル▲11▼は前後方向、テーブル▲12▼は左右方向、コラム▲13▼は回転する加工用刃物▲14▼を上下方向に移動する各機能を備えている。説明を簡略にするために、テーブル▲12▼の上に固定されている本考案の微速度送り機構を具備したバイス▲15▼によるY軸方向への被加工物▲16▼の動きについてのみ説明する。
加工を始める直前にはテーブル▲12▼はベース▲10▼に対して最も右端に移動する。従って被加工物▲16▼も最も右端に位置する。
次に、テーブルの左方向に向かってのストロークが開始され、被加工物▲16▼はコラム前面で回転する刃物▲14▼により、時間に従って加工(研・切削)が進行する。
加工ストロークの終了後には、テーブル▲12▼はベース▲10▼の最も左端に移動し、被加工物▲16▼も最も左端にストロークされて停止する。この時テーブル▲12▼は、この機械の仕様上のストロークいっぱいにA→A’の距離だけ移動し、同時に被加工物▲16▼はB→B’の距離を移動したことになる。
【0004】
【本考案の効果】
このことから、被加工物▲16▼は、仕様上のストロークよりもC→C’分だけ長い寸法の加工を行なったことになる。この場合、被加工物▲16▼はバイスから取り外されることも、左右の向きを振り替えられることもないため、寸法誤差が生じることはない。
また、本考案の考え方は、サドル▲11▼によるX軸方向(前後)への加工に対してもそのまま応用出来ることは勿論である。

[0001]
[Technical field to which the invention belongs]
Originally, machining with a machine tool in any of the three directions of the X, Y, and Z axes cannot be performed beyond the inherent stroke described in the specification. However, it is often the case for an actual worker that the stroke can be extended a little more. The present invention has been designed to cope with such a case.
[0002]
[Prior art]
In the past, the only way to machine a dimension longer than the specified stroke was to introduce a larger machine tool or to rely on outsourcing to others. Is required, and in many cases, it is not possible to cope with the constraints of the delivery date. Therefore, a method is used in which the workpiece is processed as much as possible within a predetermined stroke range, the workpiece is transferred, and the remaining portion from the opposite direction is reprocessed. However, in this method, it is necessary to remove the workpiece once from the vise and re-add it, so that it is unavoidable that a step is formed near the joint of processing, and therefore, it can not withstand high precision processing. In other words, there was a fatal defect as a machine tool.
[0003]
[Embodiment of the invention]
The implementation state of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a low-speed feed mechanism (1) and a vice (2) (three in the figure) of the present invention. The clamp (5) firmly fixes the work (work) by the screw (4) connected to the handle (3) of the vise. The vise is led by the slide way (6), and is driven by the feed screw (7) and the low-speed gad motor (8) to move on the slide way while maintaining accurate parallelism. (9) is a bolt hole for fixing the whole to the table of the machine tool.
FIG. 2 shows a state in which a vise provided with a slow-speed feed mechanism according to the present invention is mounted on a typical planing type machine tool (milling machine, surface grinding machine, etc.).
The saddle (11) on the base (10) has the functions of moving the cutting tool (14) in the front and rear direction, the table (12) in the left and right direction, and the column (13) in the vertical direction. . For the sake of simplicity, only the movement of the workpiece (16) in the Y-axis direction by the vise (15) equipped with the fine speed feed mechanism of the present invention fixed on the table (12) will be described. I do.
Immediately before starting the processing, the table (12) moves to the rightmost position with respect to the base (10). Therefore, the work (16) is also located at the rightmost end.
Next, a stroke toward the left of the table is started, and the work (grinding / cutting) progresses with time according to the blade (14) rotating on the front of the column.
After the end of the machining stroke, the table (12) moves to the leftmost end of the base (10), and the workpiece (16) is also stroked to the leftmost end and stops. At this time, the table (12) has moved by the distance of A → A ′ over the full stroke according to the specifications of the machine, and at the same time, the workpiece (16) has moved by the distance of B → B ′.
[0004]
[Effect of the present invention]
This means that the workpiece (16) was machined to have a dimension longer by C → C ′ than the specified stroke. In this case, since the workpiece (16) is not removed from the vise, and the left and right directions are not changed, no dimensional error occurs.
In addition, the concept of the present invention can of course be applied to machining in the X-axis direction (front and rear) by the saddle (11).
