涡轮叶片背向缘板空间尺寸复杂,缘板的位置尺寸保证叶片相互间的装配问题,正确理解缘板的空间位置平面形成,将缘板的空间一般位置平面转换为垂直状态,便于叶片缘板尺寸测量和测具的制造。在叶身不同转角+α度,0度,,-α度情况下,检测叶背的缘板尺寸,利用UG设计功能,采集不同转角下,叶身定位点的空间位置尺寸和叶身型面的切线方向进行定位,解决了曲面定位点手工无法计算的问题,提高了设计效率和准确性。
Turbine blade back to the edge of the board space size is complex, the location of the edge plate size to ensure the assembly of the blade between the problem, the correct understanding of the edge of the space position plane formation, the edge of the general position of the space plane into a vertical plane state, Manufacture of dimensions and measuring tools. In the case of different angles of rotation + α degrees, 0 degrees ,, - α degrees, the size of the edge of the leaf blade was detected. With the function of UG design, the spatial location of leaf blade locating points and the leaf blade profile Of the tangential direction of the positioning to solve the problem of manually positioning the surface can not be calculated to improve the design efficiency and accuracy.
