A newly developed tensile and torsional testing machine for detecting parameters such as torque, torque, pre tension, axial force, and torque coefficient of large hexagonal bolts, torsional shear bolts, and high-strength structural bolt pairs

1. Host: Adopting a horizontal structure and a steel plate worktable to ensure the rigidity of the entire machine. The motor, reducer, coupling, torsion sensor, axial tension device, etc. are located on a central axis, and the fixture is made of alloy structural steel to ensure its service life. The installation and disassembly of the sample are convenient and fast.

2. Drive system: driven by a motor reducer, with a wide speed adjustment range, uniform and stable loading.

3. Transmission system: Adopting cycloidal pinwheel reducer and coupling transmission to ensure uniform, stable and accurate transmission, and can be adjusted freely within the lateral spatial range.

4. Measurement display system: The machine uses a torque sensor to collect the torque of bolts, an axial force sensor to detect the axial force of bolts, and a LCD screen to display the torque, axial force, and torque coefficient K of the sample.

5. Data storage: Data can be saved and read and printed at any time.

6. Safety protection system: overload protection, overcurrent protection, etc.
