金博棋牌电脑版下载叶片的型里精度和外面完整性间接制约着航空发动机的事情机能及使用寿命。因为叶片具有薄壁易变形、质料易加工及砂带磨削柔性打仗等特性而难以实现周详磨削,由此提出了一种基于检测—加工一体化的自适应砂带磨削加工要领。起首凭据叶片构造特性,设想了边沿磨削工位磨头和圆角磨削工位磨头,离别用于磨削叶片型里及进排气边沿、阻尼台及根部转角等部位;其次基于模子重构的多少偏差停止了自适应软件的研制;最初经由过程双工位集成的七轴联动数控砂带磨削中央停止了叶片磨削实验。实验效果注解,磨削后的叶片外面粗拙度Ra≤0.4μm,加工偏差连结正在±0.05mm范围内,叶片型里磨削加工周期仅为3.5h,知足叶片加工要求。因而,自适应砂带磨削手艺是实现叶片周详磨削加工的有用手艺手腕。

[ABSTRACT]The profile accuracy and surface integrity of blades directly restrict the performance and service life of the aero-engine. Because of the characteristics of thin-wall deformation and difficult material processing and flexible contact, it is difficult to achieve a precision grinding. Therefore, a self-adaptive abrasive belt grinding method based on the integration of defection and machining was proposed. Firstly, according to the characteristics of the blade structure, the edge grinding and round angle grinding devices were designed, which were used to grinding the blade surface and LTE(the leading and the trailing edges), the damping table and the root corner. Secondly, self-adaptive software was developed based on geometric error of model reconstruction. Finally, the blade grinding test was carried out through the double position integrated seven axis CNC grinding center. The results show that the surface roughness of the blade is less than 0.4μm, the machining error is kept within the range of 0.05mm, and the grinding period is only 3.5h, which satisfies the processing requirements of the blade. Therefore, the self-adaptive abrasive belt grinding technology is an effective method for precision grinding of blades.
