Socket Torque Testing Machine
Category：Torsion Testing Machine
Introduction
The Socket Torque Testing Machine is a specialized testing device designed to evaluate the torsional mechanical performance of sockets, such as socket wrench sockets and bit sockets. It is primarily used to measure parameters such as torque strength, torsional deformation, maximum torque, and failure torque, helping assess the quality, durability, and safety performance of socket tools.
Application
The Socket Torque Testing Machine is primarily designed for the testing and evaluation of sockets and other torque-transmitting tools. The test socket is securely mounted between adjustable fixtures, allowing the spacing to be adapted to different specimen sizes and enabling torsional mechanical performance testing under various test conditions.The machine adopts computer-controlled operation and can acquire and analyze key test data, including:
Torque
Peak Torque
Torsion Angle
Torque–Time Curve
Torque–Torsion Angle Curve
Torque–Rotation Angle Curve
The test software/display system provides real-time visualization of the relevant test curves, enabling detailed evaluation of the socket’s torque performance, torsional behavior, and failure characteristics.
