凿岩机零件棘轮需要铣27个齿,过去采用分度头手工分度,工效差,劳动强度大,质量不高。一九七三年我们制成自动分度器代替手工分度。在铣床刀架上装有横梁,横梁上装有四个单向挡块,分度头装在铣床工作台上。分度头由座、圆锥滚子轴承、主轴、锁紧电磁铁开关、分度拨义、分度棘轮、锁紧电磁铁、螺母等组成。被加工单件的心轴涨胎装在主轴锥度孔内,单件由涨胎涨紧,每次加工3个单件。铣削凿岩机棘轮齿,由于采用了分度精度较高的分度棘轮,因而分度均匀。工作中分度棘轮由电磁铁锁紧,消除了振动。加工光洁度较高。采用机床附件磁块使工作台往复连续运
Rock drill parts ratchet need to milling 27 teeth, past the use of sub-indexing manual indexing, ergonomics, labor intensity, quality is not high. In 1973 we made an automatic indexer instead of manual indexing. In the milling machine turret is equipped with beams, the beam is equipped with four one-way stop, dividing head mounted on the milling table. Indexing head by the seat, tapered roller bearings, spindle, lock solenoid switch, indexing division, indexing ratchet, locking solenoid, nut and other components. Spinning spindle is processed single piece installed in the spindle taper hole, single piece up by the inflation tight, each processing 3 single. Milling rock drill ratchet teeth, due to the use of indexing ratchet higher accuracy, thus indexing uniform. Indexing ratchet work by the electromagnet locking, eliminating the vibration. Processing finish higher. The use of machine accessories magnet block reciprocating workbench shipped
