Description
本發明係關於一種工具夾持裝置，特別是指一種具有一組合式微孔彈性夾頭的工具夾持裝置。The invention relates to a tool holding device, in particular to a tool holding device with a combined micro-hole elastic chuck.
隨著科學技術的不斷發展，航空工業、國防工業、機械、積體電路板、汽車、精密儀器、鐘錶和珠寶等行業，對於產品精細化程度的要求日漸提高，在產品製造過程中，需要鑽製Φ3.0mm以下微孔的零部件越來越多。上述大深徑比的微孔(孔徑小於Φ3.0mm)加工是一項世界性的加工難題。目前，常用的微孔加工主要有鑽、沖、銑削等機械加工方式以及放電加工、超音波、雷射、電解、電子束加工等特殊加工方式。With the continuous development of science and technology, the aviation industry, defense industry, machinery, integrated circuit boards, automobiles, precision instruments, clocks and jewellery and other industries have increasingly demanded products with a higher degree of refinement. More and more parts are made for pores smaller than Φ3.0mm. The above-mentioned processing of micro-holes with a large depth-to-diameter ratio (pore diameters less than 3.0 mm) is a worldwide processing problem. At present, the commonly used micro-hole machining mainly includes machining methods such as drilling, punching and milling, as well as special machining methods such as electrical discharge machining, ultrasound, laser, electrolysis, and electron beam machining.
針對機械加工方式，目前通用的加工機床夾頭，一般是夾持Φ3.0mm以上的刀具比較適宜，但在夾持Φ3.0mm以下的刀具時，由於工具夾持器的夾頭體積大，製造難度高，夾持精度低，所以往往製造成本高，也較難保證加工精度，並且極易出現折斷刀具的現象，這種夾頭在機械加工行業中，常常給加工高精度微孔的操作者帶來許多不便與挑戰，同時也限制工業細微化的發展。Aiming at the mechanical processing method, the current general-purpose machining tool chucks are generally suitable for clamping tools of Φ3.0mm or more, but when clamping tools of Φ3.0mm or less, due to the large volume of the chuck of the tool holder, manufacturing The difficulty is high and the clamping accuracy is low, so it is often high in manufacturing cost, difficult to ensure the processing accuracy, and it is easy to break the tool. This type of chuck is often used in the machining industry for operators who process high-precision micro-holes. It brings many inconveniences and challenges, and also restricts the development of industrial miniaturization.
再者，要在大體積夾頭上成型一Φ3.0mm以下的微孔型刀具夾持孔，加工的困難度大幅度提高，製造成本也相對大幅度增加。另外，例如銑床、鑽床、車床等機械加工機床的種類繁多，其所使用的工具夾持器及其夾頭，在構成特徵上隨之各有不同。要在種類繁多的工具夾持器上，分別加工成型一微孔型彈性夾頭，加工難度及製造成本均呈倍數增加。Furthermore, to form a micro-hole type tool holding hole with a diameter of less than 3.0 mm on a large-volume chuck, the processing difficulty is greatly increased, and the manufacturing cost is relatively increased.
