基于逆向工程的压缩机螺杆转子快速成形加工
|
摘要
结合压缩机螺杆转子成形工艺特点,对某螺杆转子的反求过程与快速成形进行了研究。阐述了反求过程中转子的三维数字化测量、点云数据处理、转子曲面重构、三维模型重建等技术,获取了转子的三维实体模型,并利用快速成形技术,实现了转子的快速成形加工。研究结果可为新型压缩机螺杆转子的设计与制造提供参考。
Combining with the forming technology characteristics of compressor screw rotor,reverse engineering and rapid prototyping of a screw rotor are studied. The 3 D digital measurement,point cloud data processing,rotor surface reconstruction and 3 D model reconstruction in the reverse process are explained in detail. The 3 D solid model of screw rotor is obtained and rapid prototyping of screw rotor is realized by rapid prototyping technology. The results show that the research method based on reverse engineering and rapid prototyping technology can provide reference for the design and manufacture of a new type of compressor screw rotor.
