Cylindrical pins are generally used to connect, lock parts or for assembly positioning, and can also be used as parts of safety devices. Cylindrical pins are fixed in holes by interference fit to fix parts, transmit power, or serve as positioning parts. Cylindrical pins are positioning pins used to fix the relative positions between parts. They are important auxiliary parts during combined processing and assembly. Cylindrical pins are mostly made of high-quality carbon structural steel as raw materials. In general, the material is mostly C35 and C45, but heat treatment is required. Bearing steel is used under high strength requirements, and 65Mn is mostly used for elastic cylindrical pins. Cylindrical pins have simple structure, good centering, high load-bearing capacity, good variable load and impact performance, but require high machining accuracy of the mating surface.

What types of cylindrical pins are there?

1. Ordinary cylindrical pins

The pin hole should be reamed, and the cylindrical pin should be fixed in the pin hole with a slight interference. Repeated disassembly and assembly will reduce the interference, reducing the firmness and positioning accuracy of the connection.

2. Internally threaded cylindrical pins

The pin hole should be reamed, and the cylindrical pin should be fixed in the pin hole with a slight interference. Repeated disassembly and assembly will reduce the interference, reducing the firmness and positioning accuracy of the connection. It is used for positioning, connection, and can also be used as a safety pin. And the internally threaded cylindrical pin is used for blind holes.

3. Elastic cylindrical pins

A round tube with longitudinal slits and quenching is made of spring steel. Using its high elasticity, it is evenly squeezed in the pin hole, which is firm and reliable.

The requirements for the precision and surface roughness of the pin hole are relatively low, and it can be assembled and disassembled many times, but the rigidity is poor.
