针对超长轴键槽铣削情况,设计了一种简易工具(见下图),使加工精度达到(?)0.05mm以内。使用时利用工作台T型槽定位,将V型铁紧靠在T型懵一边并固定,并用分百表校正。定位盘紧固螺钉固定在工件轴的合适部位上;固定架安装在工作台上,并使定位盘的孔与固定架的定位孔同心,插入定位销固定,调整千斤顶至工件轴下母切线,压紧工件即可铣削。铣完一头槽后,只要拨出定位销,松去压板,把工作轴连同定位盘换向,再将定位销插入同一个定位孔中定位,压紧工件即可铣削另一头槽。
For the long shaft keyway milling situation, the design of a simple tool (see below), so that the processing accuracy (?) 0.05mm or less. When using the use of table T-slot positioning, the V-type iron close to the T-shaped side and fixed, and with hundreds of table calibration. The fixing plate is fixed on the worktable, the hole of the positioning plate is concentric with the positioning hole of the fixing frame, the positioning pin is inserted and fixed, the tangential line between the jack and the under-axis of the workpiece shaft is adjusted, Press the workpiece can be milling. After milling a slot, simply dial the positioning pin, loosen the platen, the working shaft with the positioning plate for the direction, and then locate the pin into the same positioning hole positioning, pressing the workpiece can be milling the other slot.
