Nuts Go-and-Stop Gauge Inspection Machine

Overview

The Openex Nuts Go-and-Stop Gauge Inspection Machine is a standard, high-speed automatic inspection system designed for M4-M16 nuts.
It replaces manual thread gauging with a dual-gauge rotary torque detection mechanism, dramatically improving efficiency and accuracy.

Operators simply load parts into the vibrating feeder bowl — from there, the system automatically feeds, inspects, classifies, and sorts the nuts without manual intervention.
With a touchscreen HMI interface, operators can easily configure torque parameters, view inspection data, count output, and monitor alarms.

This machine is particularly suited for:

• Automotive fastener nuts
• Weld nuts
• Copper and titanium electronic nuts
• Precision threaded components for general manufacturing

Key Features

Dual go-and-stop gauges feed nuts simultaneously into the rotary disk inspection station, ensuring high positional accuracy and stable operation.

Reads and controls the torque of go/no-go insertion with 0.01N·m accuracy, providing reliable torque data for every piece.

Automatic feeding, detection, and sorting reduce manpower requirements. One operator can manage multiple machines simultaneously.

Intuitive full-touch HMI panel guides operators through setup and real-time monitoring. Built-in counting and alarm systems simplify production management.

Optionally integrates with the Openex AI Vision system for real-time image analysis and defect detection on the nut surface.

The flexible threading mechanism guarantees alignment and prevents product damage during torque testing.
