平面型箱体零件粗基准表面预加工的必要性研究

The Necessity of Level Type Case Body Part Thick Basic Surface Preparatory Cut Is Studied

箱体零件是机器或部件的基础零件和基准零件,它把有关零件连接成一个整体,使这些零件保持正确的相对位置,彼此协调地工作。从分析夹具夹紧误差的角度重点分析箱体零件与夹具接触表面形貌对零件夹紧误差的影响,并通过分析阐述了箱体零件粗基准表面预加工的必要性。

The body part of the case is basic part of a machine or the part and basic part. It connects relevant parts into a whole, makes these parts keep the correct relative position, the work of coordinating each other. This text analyses especially in term of analysing total error of the jig the body part of the case and jig are exposed to the influence that the surface shape looks clamp the error to the part, and has explained the necessity of case body part thick basic surface preparatory cut through analysing.
