Vynález sa týká rlešemia krokavacieho· polohovacieho servoimechanizmu s míkroiposuvovou jednotkou, zabezipečujúceho přesné a jemné polohovanie s malým torokom a zároveň zabezpečujúceho i rýchly prestavovací .pohyb.BACKGROUND OF THE INVENTION The present invention relates to a solution of a stepping servo mechanism with a micro-displacement unit, which ensures precise and fine positioning with a small torque, while also ensuring a rapid adjusting movement.
Pri realizávcii ikrokovacích polohovacích •servomechanizmoiv vzniká problém zabezpečit prestavovaciu rýchlosť pri idanej velkosti inlkrementu pohybu, alebo naopak, natoolko maximálně možná frekveneia opakovania krokovacích pohybov je Obmedzeiná vlastnosťaimi použitého krokovacieho pohonu. Například krokový motor s velkosťou krotku ,,?»“ s pohybovou skirutkou so stupáním „s“ a maticou spojenou so saňami polohovacieho servomechanizmu umožňuje mi1•nimálny inkrement pohybu x = φ. s/2 π a maximálna rýchlosť pohybu v = x . f, kde f je maximálna prevádzková frekveneia motora. Uvedené dbmedzenie sú v doteraz používaných servomechianizmoch riešené následovně: V servomeehanizme s indukčným lineárnym alebo plošným ikrokovacím pohonom je vynechaný akýkofvek mechanický převod a pohon sa uskutečňuje priamo saňami polohovacieho servomechanizmu, čím sa dosahuje vysoká pirestavovacia rýchlosť. Přesnost napolohovania a jemnost pohybu je však daná a priamo určovaná presnosťou a jemnosťou pohonu, čo je nevýhodou tohoto riešenia, nakofko výroba taikéhoto krokovacieho pohonu je velmi obtiažna a nákladná. Servomechanizmus s jednosměnným pohonem a priamym odmerlavaním polohy využívá pre přesné a jemné polohovanie saní vhodný odmerný prvek a riadenie pohonu pomocou vhodného· regulačného obvodu so spatnou vazbou, čo za určitých podmieinok umožňuje tak jemné a přesné polohovanie •ako' je jemné a přesné odmeriavanie pomocou odmerného prvku. Nevýhoda tohoto •riešenia však spočívá v tom, že vlastnosti mechanizmu, hlavně jeho mellneairity, alko vole, pasivné odpory, ovplyvňujú vlastnosti regulačného obvodu tríadenia pohonu tak, že tento sa v ich důsledku chová v dynamickém režime nestabilně a často sposoibuje mechanické kmity saní potohovacieho mechanizmu. To v konečnom důsledku ohmedzuje použitie servomechanizmu pri vyšších rýchlostiacih.In the implementation of the stepping servo-mechanical servo-mechanisms, there is a problem of ensuring the adjusting speed at an added amount of motion increment, or vice versa, as much as possible the repetition rate of the stepping movements is limited by the characteristics of the stepping drive used. For example, a stepper motor with a size Krotký ,,? '"The motion skirutkou to climb" with "a nut connected to the carriage servo positioning allows me • 1 nimálny increment of movement x = φ. s / 2 π and maximum speed v = x. f, where f is the maximum engine operating frequency. The above limitation is solved as follows in servomechanisms used hitherto: In a servomechanism with inductive linear or surface stepping drive, any mechanical transmission is omitted and the drive is performed directly by the slide of the positioning servomechanism, thus achieving a high pumping speed. However, the positioning accuracy and the fineness of movement are determined and directly determined by the precision and fineness of the drive, which is a disadvantage of this solution, since the manufacture of such a stepper drive is very difficult and costly. One-shift servo with direct position measurement uses a suitable metering element for precise and fine positioning of the carriage and drive control by means of an appropriate • feedback control circuit, allowing for as fine and accurate positioning as certain conditions • as fine and accurate metering element. The disadvantage of this solution, however, is that the properties of the mechanism, mainly its mellneairity, alcohol, passive resistances, affect the characteristics of the control circuit of the drive shifting so that it acts unstable in dynamic mode and often promotes mechanical oscillations of the moving mechanism. . This ultimately limits the use of the servomechanism at higher speeds.
Vyššie uvedené nevýhody zmierňuje 'a technický problém rieši krakovací polohovací seirvomechainizmus s mikiroposuivovou jednotkou pozostávajúci z kroikovacej jednotky spojeinej prostredníctvoim spojky s pohybovou skirutkou, uloženou· v iradiálnyeh ložiskách a opatřenou maticou, spojenou s polohovacími saňami, podstatou kterého je, že pohybová skrutka opatřená predpínacím e lemem tom je axiálně uložená pomocou axiálneiho ložiska na pohyblivej dosike mikroposuvovej jednotky, upravenej na ráme zariadenia.The above-mentioned disadvantages are alleviated and the technical problem is solved by a cracking positioning system with a microsuspension unit consisting of a stepping unit connected by means of a clutch with a motion screw, provided with an irradial bearing and provided with a nut connected to the positioning slide. the rim of this is axially supported by an axial bearing on the movable plate of the micro-feed unit provided on the frame of the device.
