Small tolerance of cylindrical dowel pin by two sided C chamfered straight rod type for Automatic winding machine

Introduction to the types of Pin:
Pins can be used to position, transfer power and torque, and to be used as cut-off protectors in safety devices. There are many kinds of pin, such as cone pin, inner thread cone pin, cylinder pin, inner thread pin, open end cone pin, thread pin, hole pin, rounder pin and so on. Each kind of pin is of different specifications. The most common pin can be divided into cylindrical pin and round pin.

Cylindrical pin:

Cylindrical pin is a positioning pin, the main advantage is that the force is better. Used to fix the relative position between parts, it plays an important auxiliary role in assembling and assembling. Cylindrical pin requires high tolerance accuracy, otherwise fit bad, pin easy to fall out.

Cylinder pin and cone pin are different:

1, the shape is different. As the name implies, a cone pin is a cone pin, and a cone pin is actually a platform body: that is, the cone uses a plane at the parallel bottom to cut off the top of the cone and get a 'big end and a small' platform body'. Cylindrical pins are cylindrical.

2, different processing. Cylindrical pin can be pre-machined, cone pin is usually combined.

3, cylindrical pin is often suitable for accurate positioning state (processing first), cylindrical pin can only bear a small load, so it is not suitable to disassemble frequently, and cone pin installation is convenient for self-locking, and multiple disassembly has little effect on positioning accuracy. So cone pins are often used to disassemble frequently.

4, cylindrical pin can play a shear-resistant role, cone pin is often used for positioning.

5, the scope of action is different. Cylindrical pins are mainly used for positioning and can also be used as joint pins and safety pins. Cone pins are also used for positioning and can be used as connection pins.
