镗磨(又叫珩磨)是精加工孔的一种方法,比如精加工气缸、轴承孔等时都可以用这个方法。但是镗磨机价格很高,小型工厂往往缺乏这样的机器。我厂曾利用旧立式钻床进行改装,试验结果,不但保证质量,而且提高了生产率;不但改装时十分简便经济,而且在不需要镗磨时,仍可恢夏钻床原来的功能。改装后的结构如附图: (一)主轴的转动。钻床立主轴的转动机构与原钻床传动机构相同。动力是由游动及传动皮带轮,经过一对宝塔轮传到横轴,再由横轴经一对伞齿轮,转动了立主轴9及磨头10。
Boring (also known as honing) is a method of finishing holes, such as finishing cylinder, bearing holes, etc. can be used when this method. However, the high cost of boring mill, small factories often lack such a machine. Our factory has been using the old vertical drilling machine for modification, the test results, not only to ensure quality, but also improve productivity; not only conversion is very simple and economical, and when you do not need boring mill, you can resume the original function of summer drilling. Modified structure shown in the drawings: (A) the spindle rotation. Drilling machine spindle rotation mechanism and the original drilling machine transmission mechanism the same. Power is by swimming and drive pulley, after a pagoda wheel spread to the horizontal axis, and then by a pair of bevel gear on the horizontal axis, rotating the spindle 9 and grinding head 10.
