Everything You Need To Know About Spring Pin

Spring pins are headless hollow cylindrical bodies, axially slotted and chamfered at both ends. They are used for positioning, connecting, fixing etc. between parts. Spring pins need to have good elasticity and shear resistance. The outer diameter of these pins is slightly larger than the diameter of the assembly hole.

Classification of spring pins

1 . Elastic cylindrical pins

1)Light elastic cylindrical pin

2) Heavy-duty elastic cylindrical pin

The main difference between light and heavy duty is the thickness of the material and the width of the chamfer, the thickness of the heavy duty spring pin material and the width of the chamfer are larger than the light duty.

2. Rolled elastic cylindrical pin

1) light rolled elastic cylindrical pin

2) heavy rolled elastic cylindrical pin

3. Elastic cylindrical pin with teeth

1) Light elastic cylindrical pin

2) Heavy duty elastic cylindrical pin

Similar in appearance to the ordinary elastic cylindrical pin, the difference is that the axial slotting is staggered wave tooth shape.

Spring pin operation procedure

1. The elastic cylindrical pin should be assembled in place, and the pin end should be kept flush with the workpiece surface.

2. Take the workpiece and the corresponding type of elastic cylindrical pin respectively, and align the workpiece with the pin hole of the workpiece.

3. Take the inner pin and the outer pin with the wrong opening, use the hammer to put the inner pin and the outer pin into the workpiece.

4. Align the outer pin with the workpiece hole and keep the same direction of force with the workpiece, and install the flexible cylindrical pin into the workpiece with a hammer.

The assembly requirements of the spring pin

1. when assembling the outer pin and the inner pin, the pin holes should be wrong.

2. the elastic cylindrical pin is assembled with a hammer.

3. After the elastic cylindrical pin is assembled into the workpiece, the pin should be assembled in place and basically flush with the workpiece surface.

4. When assembling the elastic cylindrical pin, the pin opening direction should be the same as the workpiece force direction.
