Titanium standard parts manufacturers: what is a cylindrical locating pin

November 20, 2023

Cylindrical locating pins, also known as spring pins, is a headless hollow column, axial groove, chamfered ends, in the positioning between the parts, connection, fixed, etc.; with good elasticity and resistance to shear, the outer diameter of such pins than the assembly hole diameter is slightly larger.

Cylindrical positioning pin features:

1, column positioning pin has a simple structure, good alignment, high load carrying capacity, subject to variable load and impact performance, etc., but the cylindrical positioning pin requires high precision machining of the mating surface.

2、Cylindrical positioning pin disassembly force is large, will be scratched with the surface, belongs to the non-detachable connection. Not much interference or hydraulic mounting and dismounting, the joint is also removable.

Cylindrical positioning pins applicable occasions

Titanium standard parts manufacturers said: Cylindrical locating pins are suitable for positioning, can also be used for connection. Different requirements can be the same with the choice of different tolerance requirements of the diameter; pin hole reaming, multiple disassembly will reduce the pin's positioning accuracy and connectivity fastness, can only be used to transmit a small load. The internal thread of the cylindrical locating pin is convenient for disassembling and assembling. The positioning accuracy of threaded cylindrical locating pins is relatively low, and they are mostly used for occasions with low precision requirements.

Elastic cylindrical locating pins have elasticity, loaded into the pin hole and hole wall compression, not easy to come loose, the pin hole precision requirements are low, interchangeable holes can be disassembled and reassembled many times, rigidity is poor, not suitable for high-precision positioning for the occasions of shock, vibration, can be used instead of some of the cotter pins, cylindrical locating pins, pins, or taper pins. Hole pin and pin can be locked with another cotter pin, easy to disassemble, suitable for hinges.
