Product Description

Cylindrical pin is a commonly used mechanical connector, and the following is a detailed description of it:

1, Basic Definition and Function

A cylindrical pin is an elongated pin made of metal or plastic, with a cylindrical shape, used to insert between two or more connecting components to achieve connection, positioning, and power transmission. It usually relies on a small amount of interference fit to fix in the hole, used to fix parts, transmit power, or serve as a positioning component.

2, Main types and characteristics

There are various types of cylindrical pins, each with its specific application scenarios and characteristics:

1. Ordinary cylindrical pin:

• Features: Simple structure, good neutrality, high load-bearing capacity.

Application: Suitable for occasions with high requirements for neutrality, such as machine tools, automobiles, and power tools.

2. Internal thread cylindrical pin:

• Features: Internal thread for disassembly and assembly, with relatively low positioning accuracy, but easy to disassemble and install.

Application: Used for positioning positions that require frequent disassembly and installation.

3. Elastic cylindrical pin:

• Features: Elastic, hollow in the middle, slotted on the sides for easy assembly. Can be disassembled multiple times without damaging the inner hole, suitable for situations where disassembly is difficult.

Application: Used in situations that require frequent disassembly and low positioning accuracy requirements.

4. Perforated pins:

• Features: There are holes on the pin body, which can be locked with an open mouth pin for easy disassembly.

Application: Suitable for situations such as hinges that require frequent disassembly and connection.

3, Materials and Standards

There are various materials for cylindrical pins, including stainless steel (such as SUS304, 316, etc.), carbon steel (such as C35, C45, etc.), and bearing steel (such as Gcr15, etc.). Cylindrical pins made of different materials have different mechanical and corrosion resistance properties, and can be selected according to specific usage environments and requirements.

In addition, there are corresponding national or international standards for cylindrical pins, such as GB119 (ordinary cylindrical pins), GB120 (internally threaded cylindrical pins), etc. These standards specify the technical requirements for the dimensions, tolerances, materials, etc. of cylindrical pins, ensuring their quality and interchangeability.

4, Installation and usage precautions

1. Preparation before installation:

The pin hole should be hinged to ensure that the size, shape, and surface roughness of the hole meet the requirements of the cylindrical pin.

Apply a small amount of lubricating oil on the cylindrical pin to reduce friction and wear during installation.

2. Installation method:

Place a copper rod on the end face of the pin and gently drive the cylindrical pin into the hole.

Alternatively, use a specialized tool (such as a C-clip) to press the cylindrical pin into the hole.

3. Precautions for use:

The disassembly force of cylindrical pins is relatively high, which may scratch the mating surface and belong to non removable connections. If frequent disassembly is required, elastic cylindrical pins or other types that can be disassembled multiple times should be selected.
