我厂批量生产的内燃凿岩机中的主要零件冲击活塞(见图1),上面有六条梯形花键槽,三条是直槽,另三条是螺旋槽。原在X62W万能铣床上单刀铣削,效率低,劳动强度大,精度不高,还往往由于插错分度盘孔而造成废品。为了提高劳动生产率,减轻工人的劳动强度,多快好省地建设社会主义,我们设计、制造了这台液压半自动双面多头铣床(图2)。
I plant mass production of internal combustion rock drill impact of the main parts of the piston (see Figure 1), there are six trapezoidal spline groove, three straight groove, the other three are spiral groove. The original X62W universal milling machine single-pole milling, low efficiency, labor-intensive, accuracy is not high, but also often due to wrong interpolation sub-hole caused by the waste. In order to improve labor productivity, reduce the labor intensity of workers and build socialism more quickly and economically, we designed and manufactured this hydraulic semi-automatic double-sided bulldozer (Figure 2).
