[0002] The existing screw accuracy detection device uses a stepping motor as the power source to detect the accuracy of the screw. Due to the physical characteristics of the stepping motor, when the motor changes direction, there is a hysteresis error in the tooth shape itself, resulting in the commutation angle and the theoretical angle. There will be a large difference, which will eventually affect the accuracy of the linear accuracy; secondly, when the commutation error occurs, since the circumferential angle error of the screw stepper motor itself cannot be fed back, the error generated by the commutation in the overall linear motion It is a compound error composed of the circumferential angle error of the screw stepper motor and the commutation error of the screw itself. In actual tests, these two errors cannot be distinguished; It requires higher precision. If these two kinds of errors cannot be distinguished, the accuracy of precision analysis will be insufficient, which will affect the analysis effect and lead to poor precision of the finished screw rod.
