高尔夫球发射装置炮管的加工方法研究

Study on Machining Methods of the Gun-bore of the Golf-emitter

针对高尔夫球发射装置炮管的深孔加工技术难点,采取了辅助支承及导引、在刀具上设置排屑装置、正确选择刀具角度、专用冷却液高压输入等相应措施,并采取钻孔到一定深度间隔退刀,刀座与刀杆用左螺纹连接,工件内外圆轴线重合,镗刀座与车床主轴轴线一致,刀片在刀槽内自动定位等5项特殊措施保证了在普通车床上加工深孔炮管的高精度要求。

Aiming at the technical difficulty of deepholemachining in the gunbore of the golfemitter,this article mainly describes the methods that can ensure the requirement of high precision to machine deephole of gunbore in ordinary lathe.These methods include the adjuvant supporting and director,setting the scrapsexcluded equipment in cutting tools, selecting correct angles of cutting tools, inputting the special coolingliquid under the high pressure and five especial methods,viz. withdrawing the tool preiodically when boring hole to a certain extent, connecting the tool rest and toolholder with left screw thread,the inner and outer centerlines of workpiece being concentric,consisting the centerline of boringtoolrest with the main axis of lathe,and automatic orientation of tool face in toolslot.
