Component Specifications

Definition
An electromechanical or pneumatic device that rotates to precise angular positions to present workpieces to various stations in automated assembly, machining, or inspection systems. It typically consists of a circular table mounted on a drive mechanism with precise indexing capabilities, often incorporating locking mechanisms for stability during operations.
Working Principle
Operates through controlled rotational movement driven by servo motors, stepper motors, or pneumatic actuators. A controller sends signals to the drive mechanism to rotate the table to predetermined angular positions. Precision is achieved through mechanical detents, cam systems, or electronic positioning feedback. Locking mechanisms engage at each index position to ensure rigidity during machining or assembly operations.
Materials
Table surface: Hardened steel, aluminum alloy, or stainless steel. Base and housing: Cast iron or structural steel. Bearings: Precision ball or roller bearings. Seals: Nitrile rubber or polyurethane.

Frequently Asked Questions

What is the difference between continuous and intermittent indexing tables?

Continuous indexing tables rotate smoothly with constant motion, while intermittent indexing tables move in discrete steps with dwell periods at each station for operations.

How is indexing accuracy maintained in precision applications?

Through high-resolution encoders, precision gear systems, mechanical detents, and servo control with feedback loops. Regular calibration and maintenance are essential.

What factors determine the number of stations on an index table?

Determined by the manufacturing process requirements, available space, workpiece size, and cycle time considerations. Common configurations include 4, 6, 8, 12, or 24 stations.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
