Product Detail Page: High-Precision Manual Indexing Plungers / Spring Locating Pins

In automated production lines, jigs and fixtures, and precision equipment, every minute displacement can impact the entire operation. This high-precision manual indexing plunger (locating pin) combines efficient locking, wear resistance, and flexible customization, making it an ideal core component for improving equipment changeover efficiency and ensuring positioning accuracy.

I. Core Product Features 

1. Precise Locking Mechanism: Balancing Efficiency and Lifespan
Adopts a mechanical "pull-rotate-lock/unlock" design. Simply pull up and rotate 90 degrees to achieve automatic locking or release of the pin. This structure not only ensures micron-level high positioning accuracy and effectively prevents retraction caused by vibration, but the internal wear-resistant design also guarantees its cycle life, easily handling tens of thousands of high-frequency operations.

2. Diversified Handle Styles: Meeting Individual Aesthetic Needs
The knob head is crafted from aluminum alloy with a precision-knurled surface, offering an anti-slip, comfortable grip for operators to quickly grasp and apply force. It is available in three classic colors: black, gold, and red. This not only facilitates visual classification management on the shop floor but also matches the design styles of different equipment, enhancing overall aesthetics.

3. Flat-Head Pin Design (Supports Deep Customization)
The standard model features a flat-head pin design for uniform force distribution and a stable contact surface, suitable for most conventional flat-surface positioning scenarios. Meanwhile, to meet the requirements of blind holes, V-grooves, or special clearance needs in different working conditions, we support deep customization of pin head shapes (e.g., conical head, ball head, custom chamfer), accurately matching your drawings.

II. Product Expertise 

1. Complete Standard Specifications, Fast Delivery from Stock
To meet urgent production line maintenance and assembly needs, we cover mainstream thread and stroke specifications such as M8, M10, and M12, and maintain safety stock for standard models year-round. Standard parts are quick to select and ready to ship upon order, significantly shortening your procurement cycle.

2. Deep Non-Standard Customization: Solving Special Working Conditions
Beyond standard products, we possess strong R&D and flexible manufacturing capabilities. We support customization of stroke, spring tension, appearance dimensions, and materials according to customer drawings. Whether for space-constrained compact equipment or special scenarios requiring high pull force to prevent accidental activation, we can provide tailored solutions.

3. Premium Stainless Steel: Unaffected by Humid Environments
The main body and core pin are precision-machined from high-strength stainless steel, offering excellent rust and corrosion resistance. Whether in high-humidity cleaning workshops, food processing environments, or cleanroom medical and electronic applications, they operate stably over the long term without generating rust contamination.

4. Wear-Resistant Design: No Performance Decay After Tens of Thousands of Cycles
The internal spring and pin body undergo special heat treatment and wear-resistant coating processes, providing high fatigue resistance. Laboratory simulation tests show that the product can withstand tens of thousands of repeated insertion and extraction cycles while maintaining initial spring force and positioning accuracy, effectively reducing equipment maintenance and replacement costs.

III. Application Scenarios 

1. Workstation Switching and Positioning on Assembly Lines

In flexible manufacturing lines, it is used for the rapid repositioning of fixture plates between different workstations. Operators can simply pull the indexing plunger with one hand to quickly release the station. After moving to the target position, releasing it automatically snaps into the locating hole. This greatly shortens changeover time and improves production line OEE (Overall Equipment Effectiveness).

2. Rapid Positioning for Jigs and Fixtures

Widely used in CNC machining centers, welding fixtures, inspection jigs, and other scenarios. As a core component for quick locking and releasing, it enables rapid clamping and positioning of workpieces, ensuring repeatable positioning accuracy for each clamping and guaranteeing dimensional consistency in machining.

3. Positioning and Securing for New Energy Equipment Cabinets

In new energy storage cabinets, charging piles, and electrical control cabinets, it is used for positioning and securing cabinet doors or sliding modules. It ensures precise alignment of connectors during mating, prevents poor contact caused by physical loosening, and guarantees the reliability and safety of equipment operation.
