Are there any differences in use between fastener pins and spring fastener pins?
The elastic fastener pin is mainly used for positioning and can also be used for connection, and it is fixed in the pin hole by means of an interference fit. The elastic fastener pins used for positioning are usually not subject to load or a small load, and the number is not less than two, distributed in the symmetrical direction of the overall structure of the connected parts, the farther the better, the pins are in each The length in the connector is about 1~2 times the small diameter.
The tolerance precision required for elastic fastener pins is relatively high, otherwise the pins will easily fall out if the fit is not good. The advantage of elastic fastener pins is that the force is better.
As the name implies, the elastic pin is an elastic pin, with a hollow center and an open side, which is convenient for assembly, because the pin has shrinkage, and the reaction force after shrinkage can make the pin fit tightly with the inner hole. If the hole is 3.0, the outer diameter of the pin can be selected from two standards of 3.15-3.253.3-3.5. 3.15-3.25; 3.3-3.5.
