Mounting Flange Index Plunger

Precise positioning and fast locking is a key requirement in industrial automation, machinery and fixturing systems. For quick adjustments and repetitive positioning, many companies choose to use locating pins. Among the many types of indexing pins, the Mounting Flange Index Plunger is the ideal solution for structural installations and space-constrained scenarios due to its stable mounting structure and excellent utility.

Indexing Plunger With Horizontal Mounting Flange

What is a Mounting Flange Index Plunger?
The Mounting Flange Index Plunger, is a mechanical element that combines positioning, locking and quick release functions. It typically consists of a handle, internal spring, retractable locating pin and flange base. The Mounting Flange Index Plunger's flange mounting configuration makes it more suitable for installations requiring panel mounting or screw reinforcement than a common thread-mounted locating pin.
The basic principle of operation is: by manually pulling or rotating the handle, the internal locating pin is retracted to realize the movement or adjustment of the structure; after releasing, the spring automatically pushes out the pin to complete the precise positioning or locking. Some models are also equipped with a locking structure, which can be locked in the retracted state to prevent recovery due to vibration or accidental touch.

Application Scenarios
Mounting Flange Index Plunger is widely used in a variety of assembly and positioning scenarios in several industries due to its efficient operability and good compatibility. Typical applications include:
1. Industrial Equipment Positioning
It is suitable for limiting the position of movable parts in mechanical structures, such as slides, rails, lifting devices, etc., to prevent misalignment.

Built for heavy-duty use, our mounting flange index plunger provides rugged performance in demanding mechanical and industrial environments

2. Tooling Fixtures
In mold clamping, fixture positioning, assembly fixtures, positioning pins can achieve quick changeover and highly repeatable clamping to improve processing efficiency.

Customize your mounting flange index plunger with different knob styles, materials, and stroke lengths to match your application perfectly.

3. Automation Devices
Automation devices often need to adjust the module position during operation, the use of Mounting Flange Index Plunger can ensure the stability of the structure and convenient operation.

Tired of slow setup changes? Use a mounting flange index plunger to lock parts instantly and improve production speed with minimal effort.

4. Door & Cover Positioning & Control
It is suitable for the opening and closing control of cabinets, covers, access ports and other structures to ensure safe operation and accurate positioning of equipment.

Ensure accurate repeatability with a mounting flange index plunger. Perfect for positioning in CNC equipment and precision mechanical systems.
