Test and calibration system of electronic torque wrench

A test and calibration system of an electronic torque wrench, the system comprising:

• a base having a first end and a second end in opposite to the first end along an X axis;
• a sensing device disposed on the first end, the sensing device having a receiving socket for receiving a driving portion of the electronic torque wrench;
• a force imposing device disposed on the second end, the force imposing device having a sliding seat and a driving assembly, the sliding seat having a pushing portion for receiving a handle portion of the electronic torque wrench, the driving assembly being configured to drive the sliding seat to move along a Y axis perpendicular to the X axis, such that the electronic torque wrench imposes a torque on the sensing device, and the sensing device measures an actual torque value;
• a calibrating device signally connected with the sensing device and the electronic torque wrench, the calibrating device comprising a processing unit, a notification unit, a displaying unit, and a calibrating unit, the processing unit being configured to compare the actual torque value with a predetermined torque value of the electronic torque wrench, the displaying unit being configured to display the actual torque value, the notification unit generating a notification light based on the actual torque value, and the light signal being displayed on the displaying unit, the notification light includes a first light signal, a second light signal, and a third light signal;
• the first light signal corresponds to a safe range of torque value;
• the second light signal corresponds to a transition range of torque value, and the transition range of torque value is larger than the safe range of torque value;
• the third light signal corresponds to a warning range of torque value, and the warning range of torque value is larger than the transition range of torque value;
• the safe range of torque value ranges from 0% to 80% of a maximum torque value of the electronic torque wrench;
• the transition range of torque value ranges from 81% to 90% of the maximum torque value of the electronic torque wrench;
• the warning range of torque value ranges from 91% to 100% of the maximum torque value of the electronic torque wrench;
• wherein when the predetermined torque value is different from the actual torque value, the calibrating unit generates a calibrating signal to the electronic torque wrench for calibrating the predetermined torque value.
