Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0026] Please refer to Figures 1-5 The utility model relates to a small torque calibration device, including shell 1, rotatable connecting shaft 2 is installed in shell 1, and knob 4 is fixedly installed on connecting shaft 2, at least one elastic member 3 for providing the torsion of connecting shaft 2 is installed in shell 1, and the elastic member 3 adopts torsion spring or clockwork, and the dial 5 is fixedly arranged on shell 1, the dial 5 is provided with the scale 6 for the reference of knob 4,
[0027] When torque calibration is carried out, knob 4 is actuated, connecting shaft 2 is twisted and overcomes the elastic force of elastic member 3, and other torsions are calibrated according to the torsion value of elastic member 3.
[0028] In order to protect the knob, the protective cover 10 is detachably installed on the outside of the dial 5, the connecting block 7 is fixedly arranged on the shell 1, the jack 9 is arranged on the connecting block 7, the plug shaft 11 that can be inserted into the jack 9 is fixedly arranged on the protective cover 10, the top wire 8 is connected on the connecting block 7 through screw thread, and the rotating end of the top wire 8 can abut against the outer wall of the plug shaft 11, the plug shaft 11 is fixed by the top wire 8 after the top wire 8 is tightened, and the protective cover can be detached after the top wire 8 is loosened.
[0029] In order to facilitate the twisting of the whole shell 1, the handle 14 is fixedly arranged on the shell 1.
[0030] As described above, the small torque calibration device is placed on a stable and solid workbench during use, so that the device will not shake or displace during use.
[0031] For example, the calibration balance 12, before formal calibration, the pointer 13 and the dial 4 of the balance 12 are adjusted to the zero scale position, and the pointer 13 of the balance 12 is gently dialled by the dial 4. According to the range of the balance 12 and the actual use requirement, the torque value to be calibrated is determined, for example, the torque value corresponding to 0.2g is selected. On the calibration device, the pointer 13 of the balance 12 is dialled by the dial 4, and is twisted to the scale 6 position corresponding to the torque value of 0.2g. During the process, whether the pointer 13 of the balance 12 is moved to the 0.2g position is paid attention to, and the displacement of the pointer 13 is carefully observed, and is compared with the scale 6 position corresponding to the torque value indicated by the dial 4. Whether the displacement of the pointer 13 when the torque corresponding to 0.2g is twisted matches the expected position of the pointer 13 when the dial 4 is twisted to the 0.2g position is observed. If the actual displacement of the pointer 13 does not match the expectation, the deviation is recorded. According to the observed displacement deviation of the pointer, the balance is adjusted accordingly.
