Product Description
L-handle type Indexing Plunger
●Product Introduction
Indexing plungers (also known as knob plungers, indexing pins) are core mechanical basic components for precise positioning, quick indexing and locking in industrial equipment. The products shown in the picture are L-handle indexing plungers, which allow manual control of the extension and retraction of the front plunger pin via the horizontal handle, enabling positioning and release of workpieces/components without additional tools.
●Product Features
Convenient and Efficient Operation
The L-shaped horizontal handle design enables one-handed pulling and rotating operation, eliminating the need for auxiliary tools such as wrenches and screwdrivers. It greatly improves the efficiency of station switching and position adjustment, suitable for high-frequency operation scenarios.
High Positioning Accuracy and Reliable Locking
The plunger pin and threaded body are manufactured with precision machining technology, paired with the stable reset force of the built-in spring, achieving a repeated positioning accuracy of within ±0.02mm. The strong locking force after engagement effectively withstands shear loads, prevents workpiece displacement, and ensures machining/operation accuracy.
Robust Structure and Excellent Durability
The main body is made of carbon steel with zinc plating or stainless steel, featuring outstanding wear resistance, corrosion resistance and deformation resistance. It adapts to complex industrial environments such as workshop oil contamination and humidity, with a long service life and stable accuracy during long-term use.
Strong Installation Compatibility
The standardized thread design allows direct screwing into the corresponding mounting holes of equipment without complex modification. It supports customization of various specifications (thread size, plunger stroke, material), adapting to various needs from light load to medium-heavy load, from precision equipment to general tooling.
Safety and Anti-Misoperation
Some models can lock the retracted plunger pin by rotating the handle, avoiding positioning failure caused by accidental touch, improving equipment operation safety, and suitable for scenarios requiring temporary retention of the retracted plunger pin.
●Typical Applications
