Design of measuring tool for the pitch of chain plate

摘要

As a significate part of chain, chain plate is not only connecting links but also under tension. The characters of dimension of chain plate were studied. It is obvious that the center distance of holes is very important. A study on measuring the center distance of holes of chains is conducted to meet the requirement of manufacturing and assembling. Research on the method of measuring center distance of holes is done. The measuring tool is designed according to direct measurement. The measuring head is designed on the basis of the principle of cone self-centering. The device employs grating for its measuring part. The method and the standard of how to adjust the measuring tool are presented in this paper.
