我厂在生产6135型柴油机中,机体孔的加工,多年来一直是在摇臂钻床上,单孔逐个地进行钻削的。仅机体顶面孔就有78个,而且孔径大小不一,深浅各异,工人同志渴望能有一种专用机床进行机体孔的加工作业。为此,我厂试制成功了一台双拐板传动半自动多头钻床。这台自行设计制造的机床,经过一年半的生产使用,表明其性能可靠、加工质量完全符合生产要求,工作效率比原工艺提高20倍以上。现将这台机床的原理、结构简要叙述如下。
I plant in the production of 6135-type diesel engine, the body of the hole processing, over the years has been in the radial drilling machine, one hole for drilling one by one. Only the top of the body there are 78 holes, but the aperture size varies, different depths, workers gossip desire to have a special machine for the body hole processing operations. To this end, I plant trial success of a double plate drive semi-automatic long drilling. This machine designed and manufactured by itself, after a year and a half of production and use, that its reliable performance, processing quality in full compliance with production requirements, work efficiency than the original process increased by 20 times. Now the principle of this machine tool, the structure briefly described below.
