Abstract
Description
Claims (2)
- A kind of 1. method of the full-automatic return reference point in Digit Control Machine Tool optional position, it is characterised in that comprise the following steps:Step (1):The stroke of Digit Control Machine Tool feed shaft is divided into region 1 and region 2, institute by boundary of speed reducing switch position Region 1 is stated between speed reducing switch and negative limit switch, the region 2 is between speed reducing switch and positive limit switch;Step (2):When starting back ginseng, first check whether to receive speed reducing switch signal, counted if speed reducing switch signal is received Control machine tool feed axle returns to reference point with critical time moduli formula:Feed shaft is moved in region 1 to negative spacing direction first, then Reference point is returned to normally to return moduli formula;If not detecting speed reducing switch signal, Digit Control Machine Tool feed shaft starts to move to positive limit switch direction;Moving During dynamic, if detecting speed reducing switch signal, Digit Control Machine Tool returns to reference point normally to return moduli formula;If Digit Control Machine Tool feed shaft does not detect speed reducing switch signal during being moved to positive limit switch direction, Then Digit Control Machine Tool feed shaft returns moduli formula with region 2 and returns to reference point:The numerical control before positive limit switch signal is not detected Machine tool feed axially positive limit switch direction movement, spacing side is born in Digit Control Machine Tool feeding axial direction after detecting positive limit switch signal To movement, it is moved in region 1 and stops, then return to reference point normally to return moduli formula;An auxiliary switch for being used to detect numerical control machine tool feed shaft position, region are provided between reference point and positive limit switch In 2 times moduli formulas, if detecting auxiliary switch signal, Digit Control Machine Tool feed shaft reduces speed now, and is moved to positive limit switch After stop;The auxiliary switch is travel switch or proximity switch;Wherein, normally returning moduli formula detailed process is:Digit Control Machine Tool feed shaft starts to start in starting point, is opened with finding reference point The speed of pass moves towards positive limit switch direction, and after triggering speed reducing switch, Digit Control Machine Tool feeding axle speed reduces to rapidly 0, then Start to move to negative limit switch direction, moved towards the positive direction with finding the speed of zero pulse again after running certain distance;Work as feeding When the encoder zero pulse signal of servomotor occurs, Digit Control Machine Tool feed shaft is reached with locating speed to be stopped at reference point, is returned Join successfully.
- A kind of 2. method of full-automatic return reference point in Digit Control Machine Tool optional position according to claim 1, it is characterised in that Region 2 is returned in moduli formula, Digit Control Machine Tool feeding axially negative spacing direction movement, is detected to continue to run with after speed reducing switch signal and is set Stopped at after set a distance Δ l in region 1.
