差速器壳体精镗车组合机床的研制与应用

Study and Manufacturing of Finish Bore and Lathing Building-block Machine for the Differential Housing

差速器壳体上孔及开档平面的加工精度长期以来一直是人们关注的焦点.在本机床的研制过程中,通过对立式镗杆总成、前导向装置的设置、夹具定位方案选择、定位部件的设计与制造、调整环节的设置等方面的研究,使洛阳菲亚特90系列轮式拖拉机差速器壳体的精镗车加工达到产品的技术要求.

The machining accuracy of holes and open-seat planes in the differential housing is focused for a long time. In the process of study and manufacturing for this machine tool,by setting the vertical boring arm units,the front guide sleeve, selecting the fixture scheme, designing and manufacturing the locating units,we have successfully completed the finish boring and lathing for the differential housing on Luoyang Fiat 90 series wheeled tractor.
