Cylinder locating pins, also known as spring pins, are a type of headless, hollow cylindrical shape with axial slots and chamfered ends at both ends. They are used for positioning, connecting, and fixing parts to each other; they possess good elasticity and shear resistance. The outer diameter of these pins is slightly larger than the assembly hole diameter.

Features of the cylindrical locating pin:

The pin locating pin features a simple structure, good neutrality, high load-bearing capacity, and excellent performance under variable loads and impacts. However, the cylindrical locating pin requires high precision surface processing for mating.

2. The cylindrical locating pin has a high disassembly force, which may scratch the mating surface, making it an irreversible connection. The connection is removable if the interference fit is not significant or hydraulic assembly and disassembly methods are used.

Applicable occasions for cylindrical locating pins:

The cylindrical locating pin is suitable for positioning and also for connection. Different fit requirements allow for the selection of different diameters with varying tolerance specifications; the pin hole must be broached, and after multiple disassemblies, the pin's positioning accuracy and connection tightness will decrease, making it suitable only for transmitting moderate loads. The internal threaded cylindrical locating pin features an internal thread for easy assembly and disassembly. The locating accuracy of the threaded cylindrical locating pin is relatively low, and it is commonly used in applications where precision is not critical.

The elastic cylindrical locating pin is elastic, and after insertion into the bore, it is tightly pressed against the bore wall, making it difficult to come loose. It has lower precision requirements for the bore and the interchangeable bore can be disassembled and reassembled multiple times. It has poor rigidity and is not suitable for high-precision positioning. It is applicable in situations with impacts and vibrations and can replace some open-end set screws, cylindrical locating pins, shaft pins, or conical pins. The bore pin and shaft can be locked with an additional open-end set screw for easy disassembly, making it suitable for hinge locations.
