拉削工艺在机械制造业中被广泛地用于零件的内孔精加工,但是很少用干机械装配(包括飞机装配)的最后精加工。我厂为了提高飞机总装的结合工作效率和精加工质量,采用了拉削工艺。首先在部件装配中进行偿试,进而用于飞机总装大部件结合交点孔的精加工。这项工艺改革的成功,取得了显著的技术经济效果。飞机部件交点孔的精加工,有两种类型:一种是飞机的几何参数,靠部件处于水平测量的状态下,在精加工台中用铰孔来保证;另一种是飞机的几何参数靠总装时全机处于水平测量的状态下,采用手工铰孔的办法来保证。我
The broaching process is widely used in machine building for hole finishing of parts, but the final finishing of dry mechanical assembly (including aircraft assembly) is seldom used. I plant in order to improve the assembly of aircraft assembly efficiency and finishing quality, using the broaching process. First in the assembly of parts to be tested, and then used for the assembly of large parts of the aircraft with the intersection of the hole finishing. The success of this process reform has achieved remarkable technical and economic results. Aircraft parts intersection hole finishing, there are two types: one is the geometric parameters of the aircraft, by the components in the state of horizontal measurement, finishing hole in the table with reaming to ensure that the other is the geometric parameters of the aircraft assembly When the whole machine is in the state of horizontal measurement, the method of manual reaming is used to ensure.
