Description

精密定位鑽孔機Precision positioning drilling machine

本發明是一種精密定位鑽孔機，其是與用於金屬加工的機床有關。The present invention is a precision positioning drill which is associated with a machine tool for metal working.

市面上有一種鑽孔設備是專門適用於大形工件使用者，如第1圖所示，該鑽孔設備10包含二導軌11，該二導軌11上分別設置一精密齒排111，該二導軌11沿軸向X延伸，垂直軸向X定義為徑向Y，並有二沿敬向Y延伸之底座12可滑移地設置於該二導軌11上，則該二底座12可沿軸向X位移，而各該底座12上又分別設置一鑽孔機13及一伺服驅動單元14，該底座12藉由該伺服驅動單元14配合該精密齒排111就能驅動該底座12位移至正確的位置；然而，由於精密齒排111的位移精度往往是受限於精密齒排111的齒形結構配置，每一對應的齒部都可能產生些許的誤差，當工件長度及精密齒排111同時增長時，誤差也會持續累積，而造成位移的誤差而影響加工精度；且當該鑽孔設備10適用於大形工件，各該導軌11及設置其上的精密齒排111也都需配合適用工件的長度而增長，而該精密齒排111是造價高昂的產品，如此會使得該鑽孔設備10的成本居高不下，往往使得消費者望之卻步，有鑑於此，本發明人潛心研究並更深入構思，歷經多次研發試作後，終於發明出一種精密定位鑽孔機。There is a drilling device on the market which is specially adapted for the user of a large-shaped workpiece. As shown in FIG. 1 , the drilling device 10 includes two guide rails 11 , and a pair of precision teeth 111 are respectively disposed on the two guide rails 11 . 11 extends along the axial direction X, the vertical axis X is defined as the radial direction Y, and two bases 12 extending along the respecting Y are slidably disposed on the two guide rails 11, and the two bases 12 are axially X. Displacement, and each of the bases 12 is further provided with a drilling machine 13 and a servo driving unit 14, and the base 12 can drive the base 12 to be displaced to the correct position by the servo driving unit 14 engaging the precision tooth row 111. However, since the displacement accuracy of the precision tooth row 111 is often limited by the tooth profile configuration of the precision tooth row 111, each corresponding tooth portion may generate a slight error when the workpiece length and the precision tooth row 111 are simultaneously increased. The error will continue to accumulate, causing the error of the displacement to affect the machining accuracy; and when the drilling apparatus 10 is suitable for a large-shaped workpiece, each of the guide rails 11 and the precision tooth row 111 disposed thereon also need to be matched with the applicable workpiece. Growing in length, and the precision tooth row 111 is The high price of the product will make the cost of the drilling equipment 10 high, which often makes the consumer discouraged. In view of this, the inventors have devoted themselves to research and further conceived, and after many trials and developments, they finally invented. A precision positioning drill is available.

以上為本發明精密定位鑽孔機的結構關係，該鑽孔單元50可於該設備平台40的第二導軌41上位移，並又可連同該設備平台40於該第一導軌20上位移，而該控制單元42又因配合該第一導軌20及該第二導軌41上的光學尺30，因此該控制單元42就能借助該光學尺30的測量以驅動該設備平台40位移至準確的位置。The above is the structural relationship of the precision positioning drilling machine of the present invention.
