Product Description

E-type positioning pin description

E-type positioning pin is a mechanical fastener with a cross-sectional shape of "E", mainly used for quick positioning, connection, and anti loosening of equipment components, especially suitable for scenarios with frequent vibration or repeated disassembly and assembly. Here is its detailed description:

------

1, Basic Definition

The E-shaped positioning pin is named after its cross-sectional shape resembling the letter "E" and consists of a pin body and an elastic opening. It is inserted into the hole through elastic deformation and uses tension to achieve stable fixation, with both positioning and anti loosening functions. In the fields of mining machinery, conveying equipment, etc., traditional bolts are often replaced to solve the problem of corrosion and disassembly


Structural Features

1. Elastic opening design:

There are elastic grooves on one or both sides of the pin body, which deform and generate tension after insertion, tightly fitting the hole wall to prevent loosening.

Some models can bend the tail to form a mechanical locking structure, enhancing their anti vibration ability.

2. Wear resistant material:

Carbon steel (such as 45 # steel): After quenching, the hardness reaches HRC3648, suitable for general industrial scenarios.

Alloy steel: After heat treatment, the hardness is HRC45-55, which can withstand high loads and wear of 15.

• Tool: Hardness HRC60-63, used for precision machinery and mold manufacturing. 1. Stainless steel: Strong corrosion resistance, suitable for corrosive environments.

3. Diversified specifications:

The nominal diameter range is M16-M20 (such as 16163, 16200), and the length can be customized.

Surface treatment includes galvanizing, phosphating, etc. to enhance corrosion resistance and service life.

3, Core advantages

Quick installation: It can be fixed directly by hammering or pressing in, without the need for bolts or nuts, significantly improving assembly efficiency.

Anti vibration loosening: The elastic structure absorbs vibration energy, avoiding the loosening problem of traditional bolts caused by long-term vibration.

• Reusable: After disassembly, the elasticity recovers well and supports multiple installations (without damage).


4, Application scenarios

1. Mining and conveying equipment:

Replace the support legs, intermediate frame, and other components of traditional bolted belt conveyors to solve the problem of corrosion and disassembly.

2. Mechanical manufacturing:

The high-precision positioning of molds and precision machinery, and the pin body made of tool steel material can withstand high loads.

3. Rail transit and automobiles:

The connection of components such as chassis and wheels that require frequent maintenance, balancing convenience and reliability.

5, Installation precautions

Aperture matching: The diameter of the pin body needs to be strictly matched with the pin hole. If it is too tight, it is easy to deform, and if it is too loose, it will affect the fixing effect.

Installation method: It is recommended to lightly tap with a rubber hammer to avoid direct damage to the elastic groove caused by metal tools.

Regular inspection: In environments with frequent vibrations, it is necessary to check whether the pin body is deformed or worn, and replace it in a timely manner.
