研究设计的精铸涡轮叶片综合测具能实现叶片叶身型面各截面理论位置的测量及叶片偏移、扭转后型面的测量,并同时在该测具上能实现缘板及叶冠内表面通道点的检测要求,使叶片实现了一次定位夹紧,多项检测,直接检测出型面与缘板及叶冠内表面的相互关系,提高了叶片检测精度,避免了重复定位给叶片带来的累积误差,降低了工装的设计制造成本,缩短了新产品研制的生产周期,提高了测量效率。为了提高设计的准确性,采用三维UG建模设计,准确采集叶片通道和型面参数,解决了繁琐的空间尺寸计算,提高了设计效率和准确性。它非常适用于精铸叶片加工生产现场,是一种结构简单,操作方便的检测工具。
The research and design of the precision cast turbine blade integrated measuring tool can realize the measurement of the theoretical position of each section of the blade blade profile and the measurement of the blade offset and the twisted profile after the measurement, Surface access point detection requirements, so that the blade to achieve a positioning clamping, a number of tests, direct detection of the profile and the edge plate and the inner surface of the crown of the relationship between the increased leaf detection accuracy, to avoid the repeated positioning to the blade with To the cumulative error, reducing the tooling design and manufacturing costs, shorten the new product development cycle, improve the measurement efficiency. In order to improve the accuracy of the design, three-dimensional UG modeling and design, accurate acquisition of the vane channel and profile parameters, to solve the cumbersome calculation of the space size and improve the design efficiency and accuracy. It is very suitable for casting blade processing production site, is a simple structure, easy to operate testing tools.
