Product Description
Product Overview
This product is a press-fit elastic locating pin, made of A2-70 grade stainless steel and kept in natural color. An elastic groove is opened on the side of the pin body, giving it a certain radial compression amount. The top adopts a ball head design for easy insertion, and the hexagon socket drive hole facilitates applying press-fit force or disassembly force. It is installed in the base hole through interference press-fit, and generates clamping force through elastic deformation to realize precise positioning and anti-rotation between components, and can be disassembled and reused repeatedly.
Core Advantages
-
Elastic Press-Fit Installation: The elastic groove design on the side generates uniform clamping force after press-fit, ensuring reliable positioning and strong vibration resistance.
-
Convenient Disassembly and Maintenance: The hexagon socket design on the top facilitates installation and disassembly with tools, and the product can be reused, reducing maintenance costs.
-
Precise Centering and Guiding: The ball head design makes initial insertion centering easier, ensuring smooth and efficient installation.
-
Excellent Corrosion Resistance: A2 stainless steel material provides good corrosion resistance, suitable for various environmental conditions.
Applicable Industries
-
Precision Machinery and Mold Manufacturing: Precise positioning and anti-rotation of mold inserts, fixtures and jigs, as well as positioning of automation equipment tooling plates.
-
Automotive Manufacturing and Components: Precise positioning and assembly of internal components of engines, gearboxes, and chassis components.
-
Semiconductor and Electronic Equipment: Structural positioning inside semiconductor packaging equipment, SMT placement machines, and precision testing instruments.
-
Medical Equipment Assembly: High-cleanliness and precise positioning of components in high-end medical imaging equipment and analytical instruments.
-
Aerospace Components: Precise positioning of non-main load-bearing structures such as aircraft interior parts and airborne equipment brackets (subject to specific material specifications).
-
Robot Joints and Transmission: Positioning and fixing of collaborative robot joints, precision reducers, and transmission shaft systems.
Warm Tips
-
Before installation, please ensure that the dimensional accuracy and surface finish of the installation hole meet the requirements to ensure positioning accuracy and clamping force.
-
When pressing in, please ensure uniform force application and axial verticality; special tools or gaskets can be used for assistance to avoid tilting.
-
When disassembling, it is recommended to use a pin puller or apply uniform force through the hexagon socket to avoid damaging the pin body or the base hole by direct knocking.
