摘要
摘要:连杆机构是机械中的一种常见机构,主要用于运动方式的传递,例如将转动转化为平移,将转动转化为摆动,将平移转化为转动,将摆动转化为转动。连杆机构传动的优点是可以传递复杂的运动。通过计算各个连杆的长度,可以实现比较精确的运动传递。
一般地,连杆的结构如右图所示。可以看出,连杆的结构并不复杂,造型的难度仅为连杆体部分。所以,可以考虑首先利用草图截面的方法设计连杆的主体部分,然后再在其上添加细部结构。
该设计实例即向读者介绍采用计算机辅助设计软件进行连杆造型设计的一般方法与基本操作过程。用CAXA制造工程师进行设计造型及编程。
关键词:连杆;连杆机构;计算计辅助制造软件;CAXA制造工程师软件
ABSTRACT
Abstract: The link motion gear is in the machinery one kind anization, mainly uses in the mode of motion the transmission, for example will rotate transforms as the translation, will rotate transforms as swinging, will translate transforms as the rotation, will swing transforms as the link motion gear transmission merit is may transmit plex calculates each connecting rod the length, may realize the quite precise movement transmission.
The connecting rod structure like figure to the right shows see, the connecting rod structure is plex, the modelling difficulty only is continually the body of rod , may consider first uses the schematic diagram section the methods design connecting rod main body part, then increases the detail structure again in above.
This design example namely to the reader introduced uses puter-aided design software to carry on the connecting rod modelling design the general method and the elementary operation eo makes engineer to carry on the design modelling and the programming.
Key words:link rod; link mechanism; computer assistance manufaturing of the software; CAXAmakes engineer the software
