Problems solved by technology

According to the corresponding requirements, it is necessary to regularly calibrate the blade moving speed and the force sensor of the blade sharpness tester to ensure the accuracy of the test results. In the prior art, it is difficult to directly pass the blade due to the small moving speed. On-line calibration of the moving speed of the blade, and on-line calibration of the load cell is also difficult to achieve

Abstract

The invention relates to a blade sharpness tester calibration device, which comprises a reversing pulley, a rotating speed measurement pulley, and a calibration pull rope wound around the reversing pulley and the rotating speed measurement pulley. The blade sharpness tester calibration device further comprises a rotating speed measurement sensor used for measuring the rotating speed of the rotating speed measurement pulley. The head end of the calibration pull rope is used for being connected with a blade bearing, and the tail end of the calibration pull rope is connected with a pull rope tensioning structure. The blade sharpness tester calibration device further comprises an angle measuring device used for detecting the included angle between the head end of the calibration pull rope and the moving direction of the blade bearing. The invention provides a blade sharpness tester calibration device which can calibrate the moving speed of the blade bearing of a blade sharpness tester on line.

Description

technical field [0001] The invention relates to a calibration device for a blade sharpness tester in the field of calibration verification. Background technique [0002] The blade sharpness tester is a special tool for measuring the sharpness of the blade, which includes a tester bracket, and the tester bracket is provided with a blade seat and a blade seat driving mechanism for driving the blade seat to move up and down. When it is necessary to detect the sharpness of the blade, install the blade on the blade seat, and the blade seat driving mechanism drives the blade to move down at a fixed speed through the blade seat, the blade cuts the corresponding object, and the object produces cutting resistance to the blade, and the detection The resistance of the blade is used to judge the sharpness of the blade. [0003] Correspondingly, the blade sharpness tester includes a force measuring sensor for detecting the reaction force received by the blade after cutting into the obje...
