A pin is a commonly used mechanical part, mainly used for the connection, positioning and locking of parts.
It has a simple structure, mostly in the shape of a cylinder or a cone, and comes in various sizes. When in use, it is inserted into the corresponding holes of the parts, and the connection is achieved through interference fit, taper fit, etc., restricting the relative movement of the parts and playing the role of positioning and fixing.
For common cylindrical pins, they are positioned in the holes by interference fit and are suitable for places where precise positioning is required. Taper pins have a taper of 1:50, which features high positioning accuracy and is easy to disassemble. Split pins are used to prevent nuts and other parts from loosening. After being inserted into the notches of the nuts and the holes of the bolts, the openings are spread apart to serve the purpose.
Pins are widely used in many fields such as machinery manufacturing, automotive, aerospace, etc., and they are important parts that ensure the stability of the mechanical structure and the accuracy of the relative positions of the parts.
