Product Description

E-type Positioning Pin Description

The E-type positioning pin is a specialized mechanical fastener distinguished by its unique 'E' cross-sectional shape. Engineered for swift positioning, robust connection, and steadfast anti-loosening of equipment components, it's ideally suited for environments characterized by constant vibration or frequent disassembly and reassembly. Introducing our comprehensive guide to its functionality:

------

1, Basic Definition

Named for its distinct 'E' shaped cross-section, the E-shaped positioning pin consists of a sturdy pin body paired with an innovative elastic opening. This ingenious design allows for seamless insertion via elastic deformation, utilizing tension to ensure unwavering stability and an anti-loosening effect. It's a high-performing alternative to traditional bolts in industries like mining and conveying, effectively addressing issues of corrosion and disassembly.


Structural Features

1. Elastic Opening Design:

Featuring elastic grooves expertly crafted on one or both sides of the pin body, these deform upon insertion, creating tension that ensures a snug fit against the hole wall, effectively preventing any loosening.

Select models offer a tail-bending option, forming a mechanical locking structure for enhanced resistance to vibration.

2. Wear-Resistant Material:

Carbon Steel (e.g., 45# steel): Post-quenching, the hardness achieves HRC36-48, making it perfect for general industrial applications.

Alloy Steel: Through heat treatment, it reaches an impressive hardness of HRC45-55, capable of enduring high loads and offering wear resistance.

• Tool Steel: With a hardness of HRC60-63, it's the preferred choice for precision machinery and mold manufacturing. Stainless Steel: Provides superior corrosion resistance, ideal for harsh environments.

3. Diversified Specifications:

With a nominal diameter range of M16-M20 (examples include 16163, 16200), length options are customizable.

Surface treatments like galvanizing and phosphating are applied to bolster corrosion resistance and extend service life.

3, Core Advantages

Effortless Installation: Can be swiftly fixed by hammering or pressing in, obviating the need for bolts or nuts, thereby greatly enhancing assembly efficiency.

Anti-Vibration Loosening: The elastic structure effectively absorbs vibration energy, eliminating the loosening issues typical of traditional bolts under prolonged vibration.

• Reusable: Post-disassembly, it retains excellent elasticity, supporting multiple installations without incurring damage.


4, Application Scenarios

1. Mining and Conveying Equipment:

Ideal for replacing support legs, intermediate frames, and other components of traditional bolted belt conveyors, offering solutions to corrosion and disassembly challenges.

2. Mechanical Manufacturing:

Ensures high-precision positioning in molds and precision machinery, with tool steel construction able to withstand substantial loads.

3. Rail Transit and Automobiles:

Perfect for connecting components such as chassis and wheels that require regular maintenance, providing a balance of convenience and reliability.

5, Installation Precautions

Aperture Matching: It's crucial to ensure the diameter of the pin body precisely matches the pin hole. Too tight can cause deformation, while too loose will compromise the fixing efficacy.

Installation Method: A gentle tap with a rubber hammer is advised to protect the elastic groove from damage by metal tools.

Regular Inspection: In high-vibration environments, regularly check for deformation or wear on the pin body and replace promptly if necessary.
