　　Tapered pins are a commonly used fixing tool, shaped like a cylinder. Tapered pins not only fix parts but can also transmit power. Let's explore where tapered pins are suitable and the differences between cylindrical and tapered pins.

　　Where are tapered pins suitable for use

　　Tapered pins are mainly used for positioning in the connection of different equipment, often installed in parts that need frequent disassembly. Tapered pins have a taper of 1:50, good self-locking properties, easy installation, good self-locking, and easy disassembly. A tapered pin is actually a frustum: a cone with its top cut off by a plane parallel to the base, resulting in a frustum that is "larger at one end and smaller at the other". In mechanical equipment, tapered pins are often used as locating pins. They are matched with tapered reamed holes, and they can self-lock when subjected to lateral forces, making them easy to install and with high positioning accuracy. Tapered pins are mainly used for positioning, but can also fix parts or transmit power. They are often used in frequently disassembled occasions, and the positioning accuracy is higher than that of cylindrical pins. There are several types of tapered pins, including ordinary tapered pins, internal threaded tapered pins, screw-tailed tapered pins, and knife-tailed tapered pins.

　　Cylindrical pinWhat are the differences between it and a tapered pin

　　1. Different processing. Cylindrical pins can be pre-processed, while tapered pins are usually matched.

　　2. Cylindrical pins are often suitable for situations requiring precise positioning (pre-processed), while tapered pins are often used for frequent disassembly.

　　3. Cylindrical pins can provide shear resistance, while tapered pins are often used for positioning.

　　4. Cylindrical pins are fixed in reamed holes using a slight interference fit and can withstand small loads. To ensure positioning accuracy and connection tightness, they should not be frequently disassembled. They are mainly used for positioning, and also as connecting pins and safety pins.

　　5. Tapered pins have a taper of 1:50, good self-locking properties, high positioning accuracy, and easy installation. Repeated assembly and disassembly have little effect on positioning accuracy. They are mainly used for positioning, but can also be used as connecting pins. The pin holes need to be reamed.

　　Cylindrical pinGenerally used to connect, lock parts, or for assembly positioning. They can also be used as safety device parts. Cylindrical pins are fixed in holes by interference fit to fix parts, transmit power, or act as locating pieces. Cylindrical pins are a type of locating pin used to fix the relative positions of parts. They are important auxiliary parts in combined processing and assembly. Cylindrical pins are mostly made of high-quality carbon structural steel. Generally, the material is C35 or C45, but it needs to be heat-treated. For high-strength requirements, bearing steel is selected, and elastic cylindrical pins often use 65Mn. Cylindrical pins have a simple structure, good centering, high load-bearing capacity, and good performance under variable loads and impacts, but they require high precision in the mating surface processing.

　　Tapered pins are more suitable for mechanical parts that need frequent disassembly. I have introduced the differences between cylindrical and tapered pins above, hoping it will be helpful.
