The solution is determined based on the location of the holes that need to be located. The position degree of positioning pin hole and bearing hole is Φ0.025; the position degree of other important holes is Φ0.05; the position degree of threaded hole and bolt passing hole is Φ0.2.
application:
Locating pins are the most widely used in molds.
Including stamping mold, injection mold and so on. Their precision requirements are particularly high, and if the formwork is fixed only by bolts, it will definitely not work, so positioning pins can only be used to achieve the purpose of positioning, or to prevent errors in the installation position and direction, etc.
It has certain applications in some mechanical movement equipment, mainly used for position determination based on two-dimensional space.
