Mechanical apparatus applied to calibration of torque sensor, and method

Abstract

The invention relates to a mechanical apparatus applied to calibration of a torque sensor, and a method. One end of a force transmission plate is inserted into a U-shaped support, and the U-shaped support is fixed at one position; a handle is manually operated, a worn drives a main shaft to rotate, the force transmission plate rotates synchronously, since the force transmission plate is fixed by the U-shaped support, the U-shaped support provides a reverse acting force for the force transmission plate, and the reverse acting force and the acting force of the worm cause torque to be generated one by one on the main shaft, the worm has a self-locking feature, records a group of data every time when an angle is rotated, the size of the torque is read through a sensor digital display meter to be calibrated and a standard sensor digital display meter, readings are compared, finally, a comparison curve map is drawn, and whether a sensor to be calibrated accords with application requirements. The apparatus and method provided by the invention have the following advantages: the torque sensor calibration apparatus is accurate in calibration result and simple to operate; the adjustable measuring range is quite large, and the versatility is high; and by use of the self-locking principle of a turbine worm, the readings can be read at any fixed points, values are displayed through the digital display meters, the comparison is obvious, and the reading is convenient.

Description

technical field [0001] The invention relates to a mechanical device and method applied to torque sensor calibration. Background technique [0002] In the field of torque sensor calibration, the design of the calibration fixture is various, among which the most widely used is the torque wrench, which is divided into pneumatic wrench, electric wrench, hydraulic wrench, the disadvantage of this calibration device is that the calibration torque range is small, applicable Narrow range.
