Coiled Spring Pin Installation

Coiled pins can be easily identifi ed by the 21 4 coil cross section.

Coiled spring pin installation.

Coiled spring pins were designed for assembly. Before installation the diameter of a spring pin measures slightly larger than a drilled hole. Compared to other pins the square ends concentric chamfers and lower insertion forces ease installation. Spring pins use tension created by compression to lock tight in a hole drilled through two or more components.

Drive the pin to the desired insertion depth and be careful not to damage the host. What differentiates a coiled pin. Actual diameters are slightly larger than the diameters shown allowing pins to fit tightly when installed. A spring loaded alignment pin is fixed on the installation table.

They also have higher dynamic load capacities and accommodate wider hole tolerances. This provides the tension necessary to keep. Next simply hammer the coiled pin into the hole as if it was a nail. The simplest coiled pin installation method is to use a hammer.

Installation flexibility spirolcoiled pin prior to installation slotted pin prior to installation all spring pins have the common characteristic of a pin diameter larger than the hole diameter into which the pin is installed. The absence of a slot eliminates pin nesting and. Also known as a spiral spring pin it features a coiled spring that expands when inserted into a hole. Coiled spring pin assortments coiled spring pins are flexible after installation so they absorb shock and vibration better than slotted spring pins.

First align the coiled pin up to the hole by hand. Three types of coiled pins. Upon insertion a coiled spring pin will begin to expand to create a strong and secure environment for the joined. Coiled pins can be easily identified by the 21 4 coil cross section.

The diameter of the spring pin shrinks as it enters a drilled hole. Coiled spring pins are flexible after installation so they absorb shock and vibration better than slotted spring pins. The use of a spring loaded alignment pin is recommended for assemblies with through holes to ensure alignment is maintained between the pin and the holes of the assembly components throughout the entire installation process. The most common type of spring pin is coiled.

They are made by forming strips of metal into a spiral shape. Prior to installation all spring pins have the common characteristic of a pin diameter larger than the hole diameter into which the pin is installed.
