공작기계용 정밀가공 측정지그{Construction a machine for minuteness processing measurement jig}Precision machining jig for machine tool {Construction a machine for minuteness processing measurement jig}

본 발명은 공작기계용 정밀가공 측정지그에 관한 것으로서, 좀더 상세히는 NC공작기계 또는 CNC공작기계 등의 여러 공작기계의 작업베드에 별도의 정밀가공용 측정지그를 마련하여 측정지그에 공작물을 고정하여 가공작업시 발생되는 진동 또는 충격으로 인한 공작물의 미세한 움직임을 가공중에도 확인 가능하여 불량을 최소화 할 수 있는 것이다.The present invention relates to a precision machining measuring jig for a machine tool, and more specifically, to provide a separate precision machining measurement jig on the work bed of several machine tools such as NC machine tool or CNC machine tool to fix the workpiece to the measuring jig It is possible to check the minute movement of the workpiece due to the vibration or shock generated during the work, and to minimize defects.

일반적으로 NC공작기계 또는 CNC공작기계 등의 여러 공작기계는 공작물을 수평의 작업베드에 고정하여 공작기계의 가공부에 수직으로 고정된 절삭공구를 하강시켜 절삭공구에 의해 공작물을 수직방향으로 가공하도록 하는 것이다.In general, many machine tools such as NC machine tools or CNC machine tools fix the work piece to a horizontal work bed and lower the cutting tool fixed vertically to the machining part of the machine tool to process the work piece vertically by the cutting tool. It is.

이러한 공작기계의 작업베드에 고정된 공작물을 고정하기 위해 별도의 클램프를 마련하여 가공작업을 하나 상기 클램프의 고정력이 낮은 경우 또는 공작물을 가공시 발생하는 진동이나 충격으로 인해 공작물이 미세한 움직임이 발생하게 되어 도 작업자는 이를 확인할 수 없어 가공이 완료된 후에 측정구를 통해 불량을 확인할 수 있었다.In order to fix the workpiece fixed to the work bed of the machine tool, a separate clamp is provided to perform the machining work. However, when the clamping force of the clamp is low or the vibration or shock generated during the machining of the workpiece causes the workpiece to move finely. Even if the worker could not confirm this, after the completion of the machining was able to confirm the defect through the measuring sphere.

이렇게 가공이 완료된 후에 공작물의 불량을 확인할 수 있으며, 이때 불량으로 확인된 경우 공작물을 재작업해야 하는 하므로 이로 인한 재투입되는 가공시간으로 작업효율이 낮아 불편하였다.After the machining is completed, it is possible to check the defect of the workpiece, and if it is confirmed that the defect is to rework the workpiece, this was inconvenient because the work efficiency is low due to the re-input machining time.

또한, 공작물의 가격이 고가인 경우 또는 공작물의 여유분을 마련하기 어려운 경우에는 작업자가 불량을 제거하기 위해 보다 신중하게 작업을 하여야 하는 번거럽고 많은 시간이 소요되는 어려움이 있어 불편하였다.In addition, when the price of the workpiece is expensive or it is difficult to provide a spare portion of the workpiece, there is an inconvenience in that it is cumbersome and time-consuming difficulty for the operator to work more carefully to remove the defect.

이렇게 공작기계에서 공작물을 가공시 절삭공구에 의한 진동이나 충격으로 인해 공작물의 움직임을 가공중에도 확인이 가능하여 가공중이라도 움직임이 발견시 작업을 중지하여 공작물의 다시 셋팅하여 불량을 제거할 수 있는 지그를 선호하게 되었다.When machining a workpiece in a machine tool, it is possible to check the movement of the workpiece during machining due to vibrations or shocks caused by the cutting tool.In the case of machining, the jig can be removed by stopping the work and resetting the workpiece. Preferred
