Abstract
In today's rapid development of science and technology , measurement technology has been widely used in our lives . The CMM is already in the machinery, energy , precision instrumentation and automotive and aerospace industries has been widely used. CMM is a precision measurement equipment, but the traditional coordinate measuring machine has some shortcomings, such as easy handling, can measure large mechanical parts and so on. In this case , the portable coordinate measuring machines have come into being .
This paper focuses on studies of portable coordinate measuring arm , portable CMM arm has a simple structure , light weight, easy to carry , can be adapted to different measurement environment, etc. advantages.
This paper focuses on the mechanical structure of the portable CMM arm were studied. First introduced the development prospects of CMM key technology research status at home and abroad , measuring machine manufacturers need to know and portable coordinate measuring arm. Then introduce the CMM mechanical structure and complete structural design of portable coordinate measuring machines. Finally, a brief introduction of the portable CMM measurement principle and balance mechanism .
