  • Automatic nut internal thread quality tester
    Patent number: 11175122
    Abstract: An automatic nut internal thread quality tester is provided. The automatic nut internal thread quality tester includes a blanking module, a clamping module, a push rod module, a thread gauge driving module, and an axial pushing module. The blanking module is configured to control the nuts to be tested be blanked in series. The clamping module is configured to clamp the to-be-tested nut. The push rod module is configured to push the to-be-tested nut into the clamping module and restrict the blanking. A thread gauge of the thread gauge driving module is driven by a motor to detect the to-be-tested nut. When a torque measured by a torque sensor is greater than a threshold value, the motor reverses the thread gauge and the axial pushing module drives the clamping module away from the thread gauge.
