The aero-engine blades are mostly thin-walled with complex structures, which are prone to flutter, deformation during processing. All these characteristics make it difficult to machine the blade qualified. In order to improve the precision and efficiency of blades machining, a self-adaptive clamp machining process method is proposed in this paper. Then a self-adaptive auxiliary fixture of low-melting-point alloy which have simple structures is firstly designed based on the self-adaptive clamp method. The blade machining experiments of the low-melting-point alloy auxiliary fixture are carried out. And the experimental results show that the self-adaptive clamp method can improve both precision and efficiency in blade machining. But the low-melting-point alloy auxiliary fixture is still cumbersome and danger to the operators. Therefore, through analyzing the deformation in blade machining, an improved self-adaptive auxiliary fixture which is safe, efficient, and easy operated is re-designed.

用于叶片加工变形控制的自适应辅助治具

航空发动机叶片大多是薄壁的,具有复杂的结构,在加工过程中容易发生振颤和变形。所有这些特征使得难以加工合格的刀片。为了提高叶片加工的精度和效率,提出了一种自适应夹具加工方法。然后,基于自适应夹具方法,设计了一种结构简单的低熔点合金自适应辅助治具。进行了低熔点合金辅助治具的叶片加工实验。实验结果表明,自适应夹具方法可以提高叶片加工的精度和效率。但是,低熔点合金辅助夹具仍然很笨重,并且对操作者构成危险。因此,
