最近,我们利用差动螺纹原理设计出一种微调镗刀装置。其特点是镗刀结构可以随镗杆的直径大小,镗杆的刚度要求等不同情况而相应改变,较适用于专用机床加工箱体孔精镗工序。由于体积小、结构独立,对原有的镗杆稍加加工,即能使用。微调镗刀(附图)由镗刀7、连接螺钉4、调节螺杆3及螺母套2组成。其中调节螺杆3螺距为1.5毫米,连接螺钉4螺距为1.25毫米,拧转调节螺杆3一周,使其向左移动1.5毫米,此时调节螺杆3
Recently, we have designed a trimming boring tool using the differential thread principle. It is characterized by boring knife structure can be boring bar diameter, boring bar stiffness requirements and other different circumstances and the corresponding change, more suitable for special machine tool box hole boring process. Because of its small size, structure independent, the original boring bar a little processing, which can be used. Trim boring tool (with photos) from the boring knife 7, connecting screws 4, adjusting screw 3 and the nut sleeve 2 composition. Which adjusting screw 3 pitch 1.5 mm, connecting screw 4 pitch 1.25 mm, screwing adjustment screw 3 a week, so that it moves to the left 1.5 mm, then adjust the screw 3
