Product Description

E-type Positioning Pin: A Comprehensive Description

The E-type positioning pin is an ingenious mechanical fastener characterized by its unique 'E' cross-sectional shape. Designed for rapid positioning, secure connection, and anti-loosening of equipment components, it excels in environments prone to frequent vibrations or repeated disassembly and reassembly. Discover its detailed description below:

------

1, Basic Definition

Named for its distinctive 'E' shape, the E-type positioning pin comprises a resilient pin body and an elastic opening. This innovative design allows for insertion through elastic deformation, effectively using tension to secure a steadfast fixation. Known for its dual functions of precise positioning and anti-loosening, this pin often replaces traditional bolts in mining machinery and conveying equipment, efficiently addressing issues of corrosion and frequent disassembly.


Structural Features

1. Ingenious Elastic Opening Design:

Featuring elastic grooves on one or both sides, the pin body deforms upon insertion, generating tension that snugly fits against the hole wall to prevent loosening.

Certain models enhance their anti-vibration capabilities by allowing the tail to bend and form a mechanical locking structure.

2. Robust, Wear-Resistant Material:

Carbon Steel (e.g., 45# steel): Post-quenching, the hardness reaches HRC36-48, suitable for general industrial use.

Alloy Steel: Undergoes heat treatment to achieve hardness of HRC45-55, capable of enduring high loads and wear.

• Tool Steel: With a hardness of HRC60-63, it's ideal for precision machinery and mold manufacturing. Stainless Steel boasts strong corrosion resistance, perfect for harsh, corrosive environments.

3. Versatile Specifications:

Offers a nominal diameter range of M16-M20 (e.g., 16163, 16200), with customizable lengths to meet diverse needs.

Sophisticated surface treatments like galvanizing and phosphating elevate corrosion resistance and extend service life.

3, Core Advantages

Effortless Installation: With options for hammering or pressing in place, it eliminates the need for bolts or nuts, significantly boosting assembly efficiency.

Superior Anti-Vibration Loosening: Its elastic structure masterfully absorbs vibration energy, preventing the loosening characteristic of traditional bolts under prolonged vibrations.

• Remarkably Reusable: Maintains elasticity post-disassembly, supporting multiple installations without damage.


4, Application Scenarios

1. Mining and Conveying Equipment:

Elegantly replaces support legs, intermediate frames, and other components in traditional bolted belt conveyors, resolving corrosion and disassembly challenges.

2. Mechanical Manufacturing:

Ideal for high-precision positioning in molds and precision machinery, with tool steel pins enduring high loads gracefully.

3. Rail Transit and Automotive Industries:

Perfect for connecting components like chassis and wheels, where frequent maintenance demands a balance of convenience and reliability.

5, Installation Precautions

Precise Aperture Matching: The pin body diameter must precisely match the pin hole. A tight fit may lead to deformation, whereas a loose fit compromises fixing efficacy.

Installation Technique: A gentle tap with a rubber hammer is recommended to avoid direct damage to the elastic groove, which metal tools may cause.

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