Main Description:
6.1 Host: The host has a platform structure, and all loading devices are installed on the platform. The host has high enough rigidity to ensure the accuracy of test data.
6.1.1 A deceleration loading mechanism composed of a motor and a low-speed and high-torque planetary gear reduction device is installed on the platform.
6.1.2 The other end of the platform is equipped with a rigidly fixed torsion mechanism. This mechanism can move along the linear guide rail on the flat plate and is suitable for testing and installation of high-strength bolts of different lengths.
6.1.3 The low-speed torque drive device consists of a motor and a cycloidal pinwheel reduction mechanism. Its output end is equipped with a high-precision torque sensor and a bolt axial force sensor to ensure the accuracy of the data.
6.1.4 Wear safety protection devices such as protective covers. It has protection or automatic shutdown functions such as overload, sample breakage, and test end.
6.1.5 As needed, key components are mainly processed through CNC machine tools, machining centers and other precision machine tools as the main equipment, ensuring the processing accuracy and assembly accuracy requirements.

In addition to using general measuring tools for testing equipment, more advanced testing instruments are used to detect key technical components.
6.2 Control and data acquisition system:
The digital acquisition system configuration includes torque, bolt axial force, rotation, and other loop channels. In the axial direction, the bolt axial force of high-strength bolts during the test can be measured, and at the same time, the torque and rotation angle of high-strength bolts can be measured. , the torsion coefficient can be calculated through the data processing system.
By controlling the entire test process, the data acquisition system installed in the computer collects test data. The computer screen displays the test torque, bolt axial force, and torque coefficient in real time. In addition, the system's test parameter file system makes it easy to upgrade.
6.3 Computer and test software:
     The computer screen displays the test data and draws the torque-bolt axial force, angle-bolt axial force, torque coefficient-time test curves. The computer automatically processes the data according to the standards and prints the test report.




6.4 Torsion mechanism:
     The torsion mechanism is a special torsion mechanism specially designed and produced for bolts. This mechanism includes two parts: torsion and axial tension, and the torsion and axial tension test data can be tested from the testing device connected to the torsion mechanism. In addition, the rotation and elongation can also be measured simultaneously through a special device. . During the test, the bolt is installed on the attachment of the mechanism, and the force is transmitted to the bolt through the connector by controlling the low-speed and high-torque reducer connected to the motor. The nut moves in the tightening direction through the rotation of the bolt. While twisting, the axial tensile force is transmitted to the pressure measuring end face of the bolt axial force sensor, so that the torque and axial bolt axial force can be measured while completing the test.
