Specific implementation mode
Below in conjunction with attached drawing, the present invention is described in detail.
As shown in Figs. 1-3, a kind of torque wrench life test machine, including the load of test desk 1, torsion-testing mechanism, torque
Mechanism 9 and power control cabinet 7, test desk 1 include table frame and the work top being set in table frame, and torsion-testing mechanism includes that torque passes
Sensor 2, driving adapter 3, toggle 4, reduction box 5 and motor 6, work top are provided with hollow mounting bracket, turn round
Square sensor 2, driving adapter 3 are installed on by bearing in the central cavity of mounting bracket, and driving adapter 3 is located at torque biography
The convex square toes of the lower section of sensor 2,2 lower end of torque sensor stretch into the recessed square hole of 3 upper surface of driving adapter, reduction box 5, electricity
Machine 6 is fixedly connected with table frame, and motor 6 passes sequentially through the convex side of reduction box 5, toggle 4 and 3 lower end of driving adapter
Head connection, torque loading mechanism 9 are set to corresponding to torque sensor 2 on work top, the circuit system and motor of power control cabinet 7
6 electrical connections.
The present invention can install the torque sensor 2 of 3 different ranges respectively, make testable torque range ability from
