Product Description
Introduction to Pull-Ring Type Indexing Plunger
●Product Introduction
The pull-ring type indexing pin, also known as a positioning pin or detent pin, is a rapid positioning and locking component widely used in mechanical equipment and fixture jigs. Its core function is to achieve precise positioning and separation between two components through a simple "pull" and "release" action.
●Structural Features
Rapid Operation, High Efficiency:
The "pull-to-release, release-to-lock" operation requires no tools, significantly reducing time for fixture changes or mold adjustments, and markedly improving production efficiency.
Precise Positioning, Good Repeatability:
Manufactured with precision, the fit between the pin shaft and positioning hole has minimal clearance, ensuring components are locked in the exact same position every time, guaranteeing machining or assembly accuracy.
Safe and Reliable, Strong Locking Force:
The built-in powerful spring provides consistent locking force, effectively resisting vibration and shock, preventing accidental disengagement during operation, and ensuring high safety.
Robust Structure, Long-Lasting Durability:
Typically made from high-strength alloy steel and undergoing heat treatment (e.g., quenching) and surface treatment (e.g., zinc plating, blackening, hard chrome plating), it offers high wear resistance and fatigue strength, resulting in a long service life.
Visual Status Indication:
The extended or retracted status of the pin shaft is clearly visible, allowing the operator to confirm at a glance whether locking is engaged, preventing operational errors.
Variety of Types, Strong Adaptability:
Besides the standard type, there are variants with threaded mounts, corrosion-resistant types (stainless steel material), and different pull-ring styles (e.g., button type) to suit various installation and operational requirements.
●Typical Applications
Due to their efficiency and reliability, pull-ring type indexing pins are extensively used in the following fields:
★Fixture Jigs and Molds:
Rapid Die Changing for Stamping Molds: Used for quickly positioning and locking upper and lower dies, a standard configuration for automated production lines enabling quick mold changes.
Welding Jigs: Used for positioning and clamping workpieces for welding, ensuring welding accuracy.
Inspection Fixtures: Used in measuring equipment to precisely secure parts being measured.
★CNC Machining Centers:
Pallet Exchange Systems: Used for precise positioning and locking between the machining center pallet and worktable, enabling automated loading and unloading.
Fixture Base Plate Positioning: Used in multi-station fixtures for quickly changing different fixture modules.
★Automation Equipment and Robotics:
End-Effector Quick-Changers: Robots can use pull-ring type indexing pins to quickly change different grippers, suction cups, or tools.
Mechanical Stops and Locks: Used for safely locking frequently opened or adjusted parts like protective doors and tilting mechanisms within equipment.
★Construction Machinery and Heavy Equipment:
Used for boom angle positioning, outrigger locking, and various linkage mechanisms requiring manual adjustment and locking.
★Other Industrial Fields:
Found in printing machinery, textile machinery, food packaging machinery, and even stage machinery – anywhere rapid, precise, manual locking and separation is needed.
