Product Description

E-type Positioning Pin Description

The E-type positioning pin, a marvel of engineering, is a mechanical fastener boasting a unique 'E' cross-sectional shape. Crafted for excellence, this pin is instrumental for the rapid positioning, secure connection, and anti-loosening of equipment components. It shines in environments characterized by frequent vibrations or repeated assembly and disassembly. Discover its comprehensive description below:

1, Basic Definition

The E-shaped positioning pin captures its name from its innovative 'E' cross-sectional design, comprising a robust pin body and an elastic opening. Ingeniously inserted into a hole through elastic deformation, it secures fixation through tension, boasting both impressive positioning and anti-loosening capabilities. In the realms of mining machinery and conveying equipment, this pin replaces traditional bolts, triumphing over issues of corrosion and disassembly.


Structural Features

1. Elastic Opening Design:

Ingenious elastic grooves adorn one or both sides of the pin body, deforming to create tension upon insertion. This ensures a snug fit against the hole wall, preventing any loosening.

Select models feature a tail that bends to form a mechanical locking structure, amplifying their resistance to vibrations.

2. Wear-Resistant Material:

Carbon Steel (e.g., 45# steel): Post-quenching, exhibits a hardness of HRC36-48, ideal for general industrial applications.

Alloy Steel: With heat treatment, it reaches a hardness of HRC45-55, enduring high loads and wear up to 15.

• Tool Steel: Achieves a hardness of HRC60-63, optimal for precision machinery and mold crafting. 1. Stainless Steel: Offers robust corrosion resistance, perfect for corrosive environments.

3. Diversified Specifications:

Boasting a nominal diameter range of M16-M20 (models like 16163, 16200), lengths are customizable to fit diverse needs.

Surface treatment includes galvanizing and phosphating to bolster corrosion resistance and extend service life.

3, Core Advantages

Quick Installation: Achieve fixation effortlessly by hammering or pressing in, eliminating the need for bolts or nuts, thereby significantly boosting assembly efficiency.

Anti-Vibration Loosening: The elastic construction absorbs vibration energy, preventing the common loosening issues faced by traditional bolts under prolonged vibrations.

• Reusability: Post-disassembly, it retains elasticity superbly, accommodating multiple installations without damage.


4, Application Scenarios

1. Mining and Conveying Equipment:

Supplant traditional bolted belt conveyor components like support legs and intermediate frames, resolving corrosion and disassembly challenges.

2. Mechanical Manufacturing:

Facilitates high-precision positioning in molds and precision machinery, with a pin body crafted from tool steel to withstand high loads.

3. Rail Transit and Automobiles:

Ensures the reliable connection of frequently maintained components like chassis and wheels, harmonizing convenience with reliability.

5, Installation Precautions

Aperture Matching: It's crucial for the pin body diameter to match the pin hole precisely. An overly tight fit may cause deformation, while a loose fit diminishes fixing efficacy.

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

Regular Inspection: In vibration-prone environments, regularly check for pin body deformation or wear, and replace promptly if needed.
