Product Description

Description of the E-type Positioning Pin

The E-type positioning pin is an innovative mechanical fastener characterized by its distinctive 'E' cross-sectional shape. This versatile pin excels in swiftly positioning, connecting, and providing anti-loosening support for equipment components. Especially adept in environments with frequent vibrations or where components undergo repeated assembly and disassembly, this pin is indispensable in maintaining operational integrity. Below is a comprehensive exploration of its features:

------

1. Fundamental Definition

The E-shaped positioning pin derives its name from its 'E' shaped cross-section, comprising a pin body equipped with an elastic opening. Upon insertion into a designated hole, it undergoes elastic deformation, creating tension that ensures robust fixation with anti-loosening capabilities. Widely adopted in fields like mining machinery and conveyor systems, it serves as an effective alternative to traditional bolts, addressing challenges of corrosion and disassembly.


Structural Characteristics

1. Elastic Opening Design:

The elastic grooves strategically positioned on one or both sides of the pin body deform upon insertion, generating tension that firmly secures the pin to the hole's wall, effectively preventing loosening.

Certain models offer the option to bend the tail, creating a mechanical locking structure that significantly bolsters anti-vibration capabilities.

2. Wear-Resistant Material:

Carbon steel, such as 45 # steel, undergoes quenching to achieve a hardness of HRC36-48, making it suitable for general industrial applications.

Alloy steel, post-heat treatment, attains a hardness of HRC45-55, enabling it to endure high loads and severe wear.

• Tool: Achieving a hardness of HRC60-63, it is ideal for precision machinery and mold manufacturing. 1. Stainless steel boasts excellent corrosion resistance, perfect for corrosive environments.

3. Diverse Specifications:

The nominal diameter ranges from M16 to M20 (e.g., 16163, 16200), with customizable lengths.

Surface treatments, including galvanizing and phosphating, are applied to enhance corrosion resistance and prolong service life.

3. Core Advantages

Swift Installation: Easily secured by hammering or pressing, eliminating the need for bolts or nuts and vastly improving assembly efficiency.

Anti-Vibration Loosening: The elastic structure effectively absorbs vibration energy, preventing the loosening typically seen with traditional bolts subjected to prolonged vibrations.

• Reusability: The pin retains its elasticity well after disassembly, supporting multiple installations without damage.


4. Application Scenarios

1. Mining and Conveying Equipment:

Optimal for replacing support legs, intermediate frames, and other components of traditional bolted belt conveyors, effectively addressing challenges of corrosion and disassembly.

2. Mechanical Manufacturing:

Essential for high-precision positioning in molds and precision machinery, with tool steel pin bodies capable of withstanding substantial loads.

3. Rail Transit and Automobiles:

Facilitates the connection of components like chassis and wheels, requiring frequent maintenance while balancing ease of access and reliability.

5. Installation Precautions

Aperture Matching: It is crucial that the pin body diameter precisely matches the pinhole. A tight fit might cause deformation, while a loose fit can undermine fixation.

Installation Method: A gentle tap with a rubber hammer is recommended to avoid direct damage to the elastic groove by metal tools.

Regular Inspection: In vibration-prone environments, routinely check for deformation or wear of the pin body, replacing it promptly if necessary.
