The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified
As Fig. 1, Fig. 2, shown in Figure 3, control cabinet 2 of the present utility model is fixed on the lathe with stepper motor 3, control cabinet is provided with indicator lamp 1, stepper motor is equipped with first gear 4 for 3 times, first gear 4 and empty second gears engaged that is enclosed within on the central shaft 11, clutch shaft bearing 5 is housed on the central shaft 11, clutch shaft bearing 5 inner rings and central shaft 11 are interference fit, clutch shaft bearing 5 outer rings and second gear 12 are fixed together, clutch shaft bearing 5 outer ring circumference are provided with transverse arm 13,13 times connection linear electric motors 14 of transverse arm, central shaft 11 lower ends are that ball secondary 6 cooperates with knife bar 17 upper ends that cutter 9 is housed, ball pair 6 is provided with two lock-screws 16, two lock-screws 16 become 90 ° of distributions in the XY plane, knife bar 17 both sides that cutter 9 is housed are equipped with telescopic arm 8 respectively, the effect of telescopic arm 8 mainly is can be according to the distance between workpiece size adjustment two displacement transducers, the non-contact displacement transducer 15 towards workpiece 10 all is equipped with in two telescopic arms, 8 ends, the telescopic head of linear electric motors 14 links to each other with the telescopic arm 8 of a side, the inner ring of second bearing 7 and knife bar 17 are interference fit, affixed on second bearing, the 7 outer ring circumference with two telescopic arms, 8 overcoats, two telescopic arms become 180 ° of connections on the second bearing outer ring circumference, non-contact displacement transducer 15 connects single-chip microcomputer with detection signal by the A/D conversion, and single-chip microcomputer moves up and down the telescopic head of processing signals by D/A conversion and control linear electric motors 14 by computing.
Adjustment process of the present utility model is as follows:
The utility model adopts the independent current source power supply, during use it is loaded on electric spark machine tool main shaft top, clips cutter 9, and workpiece 10 is placed cutter 9 belows, presses switch, and beginning is from dynamic(al) correction.Two non-contact displacement transducers 13 are gathered range data at directions X, by the 8096A/D conversion chip two range simulation signals are converted to data signal and import single-chip microcomputer into and handle.If two distances are unequal, then calculate the distance that linear electric motors 14 should elongate or shorten according to predefined gap-adjustment amount model, and the result passed to governor motion by the D/A conversion chip, carry out the accurate adjusting of distance to a declared goal, after adjusting is finished, two sensors detects once more, if distance is also unequal, then repeats above-mentioned adjusting; If distance equates that then single-chip microcomputer decommissions.After treating that operating personnel are with the screw-driving on the secondary directions X of ball, press switch, single-chip microcomputer works on, stepper motor drives the two sensors half-twist, carry out identical sampling, adjusting in the Y direction, thereby make on the reference planes orthogonal two straight lines (X-axis, Y-axis) parallel, reach the cutter processing plane purpose parallel with surface of the work with surface of the work.After correction on the directions X is finished, the lock-screw 16 of ball pair 6 is tightened, ball pair 6 can only be rotated around X-axis; When the Y direction also proofread and correct finish after, another lock-screw 16 of ball pair 6 is tightened, thereby ball pair 6 is locked fully, indicator lamp is bright, cutter 9 can be processed.
The above-mentioned specific embodiment is used for the utility model of explaining; rather than the utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection domain of the present utility model.
