TEST BENCH FOR CHECKING THE CORRECT FUNCTIONING OF A TIGHTENING TOOL, SUCH AS A TORQUE WRENCH

摘要

A test bench for checking the correct functioning of a tightening tool, such as for example a torque wrench, comprising a fixed frame (2), which determines a work surface (21) on which one or more motorized cells (3) are positioned provided with a coupling (31) suitable for coupling with the tool head of a tightening tool, a movable frame (4) connected to the fixed frame by a movement means which allows the surface to be elongated along a longitudinal direction (X) of the bench for an adjustable length, said movable frame being equipped with first fixing means for the handle of the tightening tool to such movable frame, an electronic processing unit which controls these motorized cells and which is capable of imparting to the tool head of the tightening tool to be tested a rotation with predetermined values of tightening torque and angle of rotation.
