Why does everyone use fastener pins?
The fastener pin overcomes this deficiency, but the processing of the tapered pin hole is more difficult, and due to the error between the taper of the reamer and the taper of the pin, it is easy to loosen or even fall off for the connection of the moving parts. The detachable connection between the shaft and the shaft sleeve, the shaft and the handle seat, etc. on the machine tool usually adopts the fastener pin connection instead of the cylindrical pin connection, because the fastener pin is fixed in the hole by interference, and it can be easily assembled and disassembled after many times. will be damaged.
For this, we use fastener pins, which are made from spring steel coils. The fastener pin is a headless hollow cylindrical body, axially slotted, and chamfered at both ends. It is used for positioning, connection, and fixation between parts; it needs to have good elasticity and shear resistance. The outside diameter of these pins is slightly larger than the mounting hole.
