随着各种高强度、高韌性的难加工材料的出現以及金属切削加工不断向着高效率、自动化方向的发展,断屑問題已經得到了国内外的普遍重視。为使切削过程中能达到可靠断屑,我們应用“齿輪—連杆”机构的运动特点,研制了一种“齿輪-連杆”式断屑装置。該装置装于車床走刀挂輪系統内(取代車床原有挂輪),自动走刀时可使溜板箱产生周期的 With the emergence of various high-strength, high-toughness and difficult-to-process materials as well as the continuous development of metal cutting towards high efficiency and automation, the chip breaking problem has gained widespread attention at home and abroad. In order to achieve reliable chip breaking in the cutting process, we have developed a “gear-link” type chip breaking device by using the movement characteristics of “gear-link” mechanism. The device is installed in the lathe walking pulley system (instead of the original carousel), automatic knife can make the cycle box cycle
