Headed Dowel Pins

Description:

Parallel pin:

Cylindrical pin is a kind of positioning pin, the main advantage is better force. It is used to fix the relative position between parts and plays an important auxiliary role in combined processing and assembly. The tolerance accuracy required by the cylindrical pin is relatively high, otherwise, if the fit is not good, the pin will easily fall out.

The elastic cylindrical pin has elasticity, and it is pressed against the hole wall after being installed in the pin hole, and it is not easy to loosen. The precision of the pin hole is relatively low. It is suitable for occasions with shock and vibration, and can replace some cotter pins, cylindrical pins, pin shafts or tapered pins.

Tapered pin:

Tapered pins also have a positioning function and are used for connecting equipment, fixing parts and transmitting power. It is usually used where frequent disassembly is required. The self-locking property of the taper pin is very good,

The difference between cylindrical pins and tapered pins:

1. The shape is different. As the name implies, the conical pin is a conical pin, and the conical pin is actually a truncated cone: that is, the cone is truncated with a plane parallel to the bottom surface to obtain a "conical truncated body" with "one big end and one small end". Parallel pins are cylindrical.

2. The processing is different. Cylindrical pins can be pre-processed, and tapered pins are usually matched.

3. Cylindrical pins are often suitable for precise positioning (processing first). Cylindrical pins can only bear a small load, so it is not suitable to disassemble frequently, while conical pins are easy to install and self-locking, and the impact of multiple disassembly on positioning accuracy is compared Small, so taper pins are often used in places where disassembly is frequent.

4. Cylindrical pins can resist shearing, and conical pins are often used for positioning.

5. The scope of action is different. Cylindrical pins are mainly used for positioning, and can also be used as coupling pins and safety pins. Tapered pins are also used for positioning and can be used as coupling pins.
