0.15-0.6N.m |
Use a spring with a wire diameter d = 2.5 |
2. Installation of the buffer: According to the needs of the test, select the bearing and spring, then rotate it counterclockwise to install the spring.
3. Inspection of the buffer:
A. Check the buffer before use. Dust, lack of grease and bending of the sleeve will affect the accuracy of the torque test.
B. Check the buffer regularly, and use the buffer repeatedly for a long time will cause the wear of the buffer and affect the accuracy of the torque test.
Twelve screwdriver torque test procedures
1. Install the buffer on the torque test head of the torque tester, and then assemble the screwdriver batch on the buffer.
2. Press the switch of the screw to the automatic state, use your fingers to reverse the force, and relax the spring of the buffer a little.
3. Press the peak key to select the PEAK peak hold state.
4. Press the zero key, the torque value on the LCD screen is zero.
5. Press the switch of the screwdriver to automatic, twist the screwdriver until the screwdriver stops automatically.
6. When the screwdriver stops rotating, the torque value displayed on the LCD screen is the torque output by the screwdriver. Repeat the above 2-5 operation to verify the output torque of the screwdriver. Loosen or tighten the torque adjustment nut of the screwdriver so that the torque of the screwdriver meets the needs of use.
