该机床为加工7655凿岩机阀套的Φ8.5毫米孔(多孔)的组合机床。机床采用四工位标准回转工作台和液压滑台,并配设专用主轴箱成立式布置,构成四工位立式组合钻床。回转工作台的回转、定位、夹紧和工件夹紧以及液压滑台的快慢进给均采用液压驱动。三工位加工,一工位装卸料,上下料时间可与加工时间重合,实现半自动钻孔加工。阀套是凿岩机的易损零件之一,消耗量大,要求产量高,每个零件有11个φ8.5毫米孔,过去在立钻上加工,每次加工一个孔生产效率低,工人操作繁琐,自制成这台机床后,由于 The machine is a combined machine tool with Φ8.5 mm holes (perforated) for machining 7655 rock drill valve sleeve. The machine adopts four-station standard rotary table and hydraulic sliding table, and equipped with a special headstock set up to form a four-station vertical combined drilling machine. Rotary table rotary, positioning, clamping and workpiece clamping as well as the hydraulic slide speed feed are driven by hydraulic. Three-station processing, a station loading and unloading, loading and unloading time coincides with the processing time, to achieve semi-automatic drilling. The valve sleeve is one of the vulnerable parts of a rock drill. It consumes a lot and requires high output. Each part has 11 φ8.5 mm holes. In the past, it was processed on vertical drilling. Each hole was processed with low productivity and workers were cumbersome. , Since the machine made into this machine, due
