摘 要
    本篇设计是柴油机齿轮室盖钻镗专机总体及夹具设计。齿轮室盖零件的主要加工表面是外圆表面及孔。一般来说，保证平面的加工精度与保证孔系的加工精度相比，保证平面的加工精度比较容易。孔径加工都是选用专用钻夹具，夹紧方式一般选用手动夹紧，夹紧可靠。因此生产效率较高。能够满足设计要求。
    本设计将钻床和卧式镗床结构有机地结合为一体，降低了机器成本，而且节省了加工时间，提高了工作生产效率。

Abstract

    This design introduces the diesel engine gear chamber cover drill boring plane on the overall and jig design, including machining process determined design must first understand the workpiece machining process route and process calculation, boring, drilling shaft diameter is decided and preliminary selection of motor types and various machine parts. The preparation of three charts card. In the design of multi axle box, determine the transmission system, calculation of spindle coordinates, check and spindle box transmission components of the general layout drawing.
    This design will be drilling and horizontal boring machine structure are organically combined into a whole, reduces the cost of the machine, and save processing time, improve production efficiency.
Key words:  Box ；The Combination of Machine ；Tools ；Design multi-axle Box Tapping
