Dispatch of net of machine tool of Chinese numerical control: The requirement of machine tool of different and phyletic numerical control to sensor is endless also and identical, generally speaking, speed of requirement of bed of large scale computer is answered tall, medium-sized give priority to with claimed accuracy with machine tool of high accuracy numerical control. The sensor that displacement detects basically has pulse coder, linear grating, change coming back to press implement, inductive synchronized. 1, the coder of pulse of applied 　 　 of pulse coder is a kind of angular displacement (rotate speed) sensor, it can turn mechanical corner into electric pulse. Pulse coder can be divided for contact and photoelectricity type, electromagnetism type 3 kinds, among them, photoelectricity type application is more. Machine tool equipment makes medium juice sensor 　 2, the transmission that the linear grating of applied 　 　 of linear grating is benefit consumed and reflection phenomenon are made and become, commonly used measure at displacement, resolution is higher, measure precision taller than photoelectricity coder, suit to be measured at trends. In feed drive, grating feet is fixed go up in lathe bed of numerical control drilling machine, signal mirrorred the pulse that its produce to procrastinate directly board real position. Consumed bar detects the servo of position of workbench of numerical control drilling machine is system of full closed-loop control. 3, rotate the applied 　 　 of transformer rotates transformer is voltage of a kind of output and angular displacement quantity the inductive type electrical micro-machine that concerns into successive function. Rotate transformer is comprised by stator and rotor, specific for, it is comprised by winding of two a core, stator and two rotor winding, its former, auxiliary winding is placed respectively go up in stator, rotor, the corner of the electromagnetism coupling degree between former, auxiliary winding and rotor is concerned. 4, the mutual inductance that uses winding of two flat look differs along with the position and metabolic principle makes the synchronized of induction of applied 　 　 of inductive synchronized. Its function is become angle or linear displacement change inductive electromotive force phasic or amplitude, usable will measure linear or corner displacement. Inductive synchronized can be divided by its structure mix for straight formula rotate type two kinds. Synchronized of straight formula induction by scale and slide two parts are comprised, scale installation is on machine tool lathe bed, slide is installed go up at mobile component, along with workbench a mobile; rotates stator of type induction synchronized is fixed disc, rotor is rotational disc. Inductive synchronized has capacity of taller precision and resolution, interference rejection strong, service life is long, safeguard displacement of simple, Sunday run to measure, craft sex good, cost is inferior wait for an advantage. Synchronized of straight formula induction is applied at big displacement static state and trends to measure widely at present in, use at 3 coordinate to measure machine tool of numerical control of machine, programmed control, high accuracy for example heavy-duty machine tool and machining center measurement unit. Rotate the revolving stage that type induction synchronized is used at numerical control machine tool and instrument widely and in systems of all sorts of circumgyrate servo control.
