Product Description
Introduction to Non-Knob Indexing Pins
●Product Introduction
The non-knob indexing pin (also known as a push-pull or button-type indexing pin) is a mechanical component that enables rapid positioning and locking through a simple linear "push" or "pull" action. Unlike knob-type indexing pins that require rotation or pull-ring types, its key characteristic is that operation requires no twisting; locking and release are achieved solely through a single-direction linear movement. This makes it particularly suitable for applications where space is limited or rapid one-handed operation is needed.
●Structural Features
Ultimate Operational Convenience:
"Press to release, insert to lock." The operation is simple and intuitive, with a short actuation stroke and very fast speed, significantly improving operational efficiency. Ideal for processes requiring frequent locking and unlocking.
Space-Saving Design:
No protruding side rings or knobs. The compact structure requires minimal radial installation space, making it highly suitable for use inside equipment, within dense fixture arrays, or other confined spaces.
High Precision and Repeatability:
Precision-manufactured pin shafts and sleeves ensure minimal fit clearance, providing excellent repeatable positioning accuracy and guaranteeing process stability and product quality.
Safe and Reliable:
The internal powerful spring provides consistent locking force, effectively resisting vibration and shock to prevent accidental disengagement during operation. Some models feature visual mechanical lock status indication (e.g., via pin position change).
Robust and Durable:
Main components are typically made from high-strength alloy steel and undergo heat treatment. Surfaces are often treated with zinc plating, blackening, or hard chrome plating, offering good wear and corrosion resistance for a long service life.
Variety of Actuation Methods:
Primarily categorized into Press-to-Release and Pull-to-Release types. Press-type usually features a button head; pull-type might have a threaded hole or simple pull tab on the head, allowing flexible selection based on user preference and spatial constraints.
●Typical Applications
Precision Tooling and Fixturing:
Semiconductor and Electronics Industry Fixtures: Used for positioning and securing precision components like PCB boards and glass substrates in environments with high cleanliness requirements.
Measurement and Inspection Equipment: Used for quick installation and positioning of gauge blocks or workpieces, ensuring measurement accuracy.
Modular Fixture Systems: Serves as a quick-connect element for rapid changeover of fixture modules.
Automation and Robotics Integration:
Robot End-of-Arm Tooling (EOAT) Quick Changers: Acts as an auxiliary locking mechanism, working in conjunction with pneumatic or hydraulic main locks to provide precise tool positioning and a safety backup.
Equipment Safety Doors and Guards: Used for rapid locking and release of frequently opened access doors and transparent protective covers.
Medical and Laboratory Equipment:
Used for precise positioning of trays, sample holders, or removable modules in medical devices and analytical instruments, offering quiet and contamination-free operation.
In summary, the non-knob indexing pin is an efficient, space-saving positioning solution in modern precision machinery and automation systems. Its unique linear operation excels in enhancing speed and adapting to compact spaces, making it an ideal choice for designers looking to optimize equipment performance and user ergonomics.
