加工16V240柴油机的支座(图1),为减少装央时间,保证加工精度,设计制造一个多用途夹具(圈2),它可以完成下述一些工序:1.擂A、B两个平面;2.钻、铰φ11H9孔;3.钻两个φ11及锪φ20端面,钻两个φ4;4.铣φ17.5半圆弧。用一套夹具完成这样多的工序,有利经济效益,降低产品的制造成本,加速产品生产前的技术准备工作,方便工装库的管理工作。工件以前端面C、底面D、侧面E定位,通过杠杆 16V240 diesel engine processing support (Figure 1), in order to reduce the loading time, to ensure the accuracy of machining, design and manufacture of a multi-purpose fixture (circle 2), which can be completed by the following processes: 1. A beat A, B two planes; 2. drill, hinge φ11H9 hole; 3. Drill two φ11 and φ20 end face, drill two φ4; 4. Milling φ17.5 semi-circular arc. With a set of fixtures to complete such a number of processes, economic benefits, reduce product manufacturing costs and speed up the production of technical preparations before the work, to facilitate the management of tooling library.
