准备加到多少？

This design introduces the development background of the machine tool fixture and machining bracket oblique hole indexing jig design process. Design process including the selection of the orientation program, drill sets of parameters of the set-oriented program, the clamping mechanism of choice, reasons for the degree program and folder of the specific choice; settings and calculation of technical hole in the slant-hole drilling mode; fixture marked dimensions, tolerances, and technical requirements in the General Plan; workpiece machining accuracy analysis

具体设计还需要你自己来完成，在这里只向你略述一下做这个钻孔模的注意事项或者说设计思路。一：工件上的两个孔是本钻孔模的加工对象，工件在钻孔模上的定位基准要跟两个孔的设计基准相一致，即以锥套小端面定位。二：设计任何工装夹具都要考虑工件的安放、拾取的工艺性，既要方便快捷还要紧固可靠。

供参考，锁紧工件的是开口垫圈，方便快速取件。钻模体的工艺性需要考虑。

之前黑板上画个大概...
