Abstract

The invention discloses a device for calibrating a numerical control machine tool motor current-cutting load relation, which comprises a magnetorheological rotation damper, a controller of the magnetorheological rotation damper, a data acquisition card, a calibration processor, a Hall transducer, a coupling, a simulated cutting tool, a slide block, a rack and a support, wherein the magnetorheological rotation damper is connected with a main shaft of the machine tool through a gear, the rack, the simulated cutting tool or the coupling; and primary motion or feed motion of the machine tool is transformed into rotation of a shaft of the magnetorheological rotation damper. The magnitude of simulated cutting load can be obtained according to different control parameters so as to detect current data and feed the current data to the calibration processor for recording and processing, thereby realizing the calibration of the relation between the machine motor current and the cutting load. The device can be widely applied to calibration on the numerical control machine tool under the condition of a production workshop, and has the advantages of extremely quick response velocity, high precision, strong environmental adaptability, small noise and no pollution.

Description

technical field [0001] The invention relates to a numerical control machine tool calibration measurement technology, in particular to a numerical control machine tool motor current and cutting load relationship calibration device based on a magnetorheological damper. In the case of load, when it is used to calibrate the relationship between the motor current and cutting load of CNC machine tools, it is a calibration measurement tool for the development of CNC equipment. Background technique [0002] The important feature of CNC equipment is the high speed and high precision of processing.
