E-type positioning pin description
The E-type positioning pin is an innovative mechanical fastener with a distinctive 'E' shaped cross-section, expertly designed for rapid positioning, secure connection, and effective anti-loosening of components. Ideal for environments with frequent vibrations or where repeated assembly and disassembly are common, this pin stands out as a vital solution. Let us delve into its comprehensive description:
------
1, Basic Definition
Inspired by the elegant 'E' shape of its cross-section, the E-shaped positioning pin features a robust pin body complemented by an elastic opening. Its design allows for elastic deformation upon insertion into a hole, utilizing tension to ensure a steadfast and stable fixture. It combines the functions of precise positioning and anti-loosening, often replacing traditional bolts in sectors like mining machinery and conveying equipment, particularly where addressing corrosion and ease of disassembly is crucial.
Structural Features
1. Elastic opening design:
Ingeniously engineered elastic grooves on one or both sides of the pin body enable deformation, generating tension that ensures a snug fit against the hole wall, thereby preventing any loosening.
Certain models offer a unique tail-bending feature that forms a mechanical locking structure, significantly amplifying their resilience against vibrations.
2. Wear resistant material:
Carbon steel (e.g., 45 # steel): Post-quenching, its hardness reaches an impressive HRC3648, making it apt for a wide range of general industrial applications.
Alloy steel: After undergoing heat treatment, boasts a remarkable hardness of HRC45-55, adept at enduring high loads and significant wear conditions.
• Tool: With an outstanding hardness of HRC60-63, it is perfectly suited for precision machinery and mold manufacturing. 1. Stainless steel: Offers formidable corrosion resistance, ideal for use in corrosive conditions.
3. Diversified specifications:
With nominal diameters spanning M16-M20 (examples include 16163, 16200), lengths can be tailored to specific requirements.
Surface treatments such as galvanizing and phosphating are employed to bolster corrosion resistance and extend durability.

3, Core advantages
Effortless installation: Designed for direct fixation through hammering or pressing, eliminating the hassle of bolts or nuts, thereby greatly enhancing assembly efficiency.
Superior anti-vibration and anti-loosening: The elastic structure adeptly absorbs vibration energy, preventing the common loosening issues associated with traditional bolts under prolonged vibration.
• Highly reusable: Maintains excellent elasticity post-disassembly, facilitating multiple installations without any damage.
4, Application scenarios
1. Mining and conveying equipment:
Perfectly replace traditional bolted components like support legs and intermediate frames in belt conveyors to address corrosion and disassembly issues.
2. Mechanical manufacturing:
Ensures high-precision positioning in molds and precision machinery, with tool steel material pins capable of bearing substantial loads.
3. Rail transit and automobiles:
Ideal for connecting parts such as chassis and wheels that demand frequent maintenance, striking a perfect balance between convenience and reliability.
5, Installation precautions
Precision aperture matching: Ensure strict compatibility between the pin body's diameter and the pin hole for optimal performance. A too-tight fit risks deformation, while too loose a fit compromises fixing efficacy.
Proper installation method: A gentle tap with a rubber hammer is advised to prevent direct damage to elastic grooves from metal tools.
Scheduled inspections: In high-vibration settings, regularly check for deformation or wear on the pin body and replace promptly to maintain peak functionality.
