C 350 LF转塔六角车床在机床六角刀架自动定位、夹紧、退回、松开、换位往复循环过程中,退回时经常出现φ20毫米撞块撞坏变弯。以前撞弯后即更换,需要准备大量的备件,维修困难,长期得不到解决。为此,我们对机床结构进行解剖、分析和试验,终于找到了病根。由于机床运转时稍有振动,凸轮5缺口右切线与撞块4切线产生摩擦,同时,由于电动机带动六角刀架溜板2迅 C 350 LF turret hex lathe In the machine tool hexagonal turret automatic positioning, clamping, returning, releasing, changing the reciprocating cycle, the return often φ20 mm crash block crashes. Before the bend after the bend, you need to prepare a large number of spare parts, maintenance difficulties, long-term unresolved. To this end, we anatomize the machine structure, analysis and testing, and finally found the root cause. Due to a slight vibration when the machine is running, the right tangent of the cam 5 notch friction with the tangent 4 block at the same time, as the motor driven hexagonal turret 2 Xun
