Thread Assembly Tool Testing System
In order to achieve reliable bolt connections in modern industrial production processes, a reliable tightening gun is crucial. Not only must the tightening gun be calibrated and certified before assembly, but it must also be repeatedly tested during the assembly process. The purpose is to ensure continuous high performance in order to achieve optimal assembly results and meet established standards.

Application Scenario
Dynamic inspection of tightening gun during assembly process
Provide reusable usage conditions for calibration and certification of tightening systems
Calibrate torque wrench according to ISO 6789 standard
The testing of power tools meets the requirements of standards VDI/VDE 2647 and VDI/VDE 2645 Part 2, with a maximum of 500Nm
Electric hydraulic connection simulator
Torque testing and testing of rotational speed behavior of pneumatic/electric tools
Torque testing of torque wrenches and pulse power tools



Select the tool to be tested
Simply enter the number of the tool to be tested in the CEUS program, and the testing system is immediately ready to enter the testing introduction state. The main test data has been stored in the database, such as tolerance zones, connection characteristics, and statistical parameters, eliminating repeated input. Each threaded fastener rotary assembly tool tested corresponds to the tool and installation characteristics of the installation station, Once the threaded fastener rotary assembly tool is successfully paired with the threaded connection characteristics, these parameters are always related within CEUS.

Choosing a barcode or electronic recognition system to identify assembly tools enables clear and accurate identification and traceability of all tools. As long as the tester scans the identification code of the tool, they can immediately conduct the test without any additional operational steps.

In the testing state, the testing system accurately simulates the thread connection characteristics of actual tools in thread assembly. Due to the fast simulation ability of the reference connection, the testing tool can be completed in about 3 seconds. During each testing process, the testing system measures torque, angle, and speed, and the simulator can also test a fixed torque wrench. During the testing process and subsequent analysis process, the CEUS software system will display all measured values on the screen.

Throughout the entire tool testing, the CEUS user interface will guide testers to display target values in numbers and images. You can quickly browse and display the measured value map window: whether the test results of the tested tool are within or outside the tolerance zone, and the distribution of all test results within or outside the tolerance zone, and display the measured torque, corner, and rotational speed under no-load conditions. For correct analysis, graphical curves are used as observation tools to display tool characteristics during or after measurement. As the testing is automated, the tester can focus fully on the testing and tools.
