Twelve, torsion spring torque test procedure
1. According to the test requirements, select the appropriate mandrel and install the mandrel to the mounting holes of the test heads on both sides.
Then install the spring under test on the main test mandrel, one end of which is fixed by the secondary mandrel.
2. Shake the handle to make the third mandrel contact with the other end of the torsion spring, and the force value and angle will be cleared at the same time just after contact.
3. The torque value and angle value displayed on the LCD screen are zero.
4. According to the torsion spring measurement requirements, rotate the measuring handle smoothly and evenly to display the technical parameters of the torsion spring being tested.
5. Repeat the above operation to verify the technical parameters of the torsion spring.
