Technical Field

[0001] This utility model relates to the field of torque wrench testing technology, and in particular to an automated testing and data processing device for torque wrench calibrators. Background Technology

[0002] A torque wrench, also called a torque-adjustable wrench, is a type of wrench. Based on the power source, it can be divided into: electric torque wrenches, pneumatic torque wrenches, hydraulic torque wrenches, and manual torque wrenches. Manual torque wrenches can be further divided into: preset type, fixed value type, dial type, digital display type, slip type, bending type, and kilogram wrench. When the tightness of screws and bolts is critical, a torque wrench allows the operator to apply a specific torque value. Torque wrenches need to undergo torque testing before leaving the factory, currently done using a torque wrench calibrator. Existing torque wrench calibrators are widely used in metrology institutions and automotive, shipbuilding, and various power machinery manufacturing enterprises, mainly for the verification and calibration of torque wrenches. However, existing calibrators use independent drive mechanisms for each tenon joint, resulting in complex structures, inaccurate measurement results, and unsatisfactory performance. Therefore, we designed an automated testing and data processing device for torque wrench calibrators. Utility Model Content
