Degree of freedom: where the object in space, there must be six degrees of freedom, X, Y, Z three axial linear motion, and around X, Y, Z rotation movement.
In a mold consisting of two or more parts, a pin is designed which allows the two adjacent parts of the mold to be accurately positioned.
In the spindle positioning on the first) 1) mechanical cam mechanism (2) photoelectric way to coarse positioning, and then have a hydraulic or pneumatic positioning pin into the spindle pin hole or pin to achieve accurate positioning, , The spindle began to rotate.
1. Fixed locating pin 2. Replaceable locating pin 3. Tapered locating pin 4. Cutting edge locating pin 5. Standard rhombus locating pin
Locating pins are most widely used in molds.
Including stamping dies, injection molds and so on. Their precision requirements are particularly high, and if it is only by the bolt to fix the template, then certainly not work, so only with the positioning pin to achieve the purpose of positioning, or to prevent the installation location, the direction of the error and so on.
In some mechanical movement of the equipment has a certain application, mainly based on two-dimensional space to determine the location.
