Description of drawings
Accompanying drawing is the structural representation of the utility model endoporus cross grinding degree of depth Adaptive control apparatus.
The specific embodiment
The same with general endoporus face grinding machine, native system still have common endoporus face grinding machine must have work spindle 1, anchor clamps 2 and end face positioner 3 thereof (but the radial location of not shown workpiece 5 and clamp mechanism), be arranged at abrasive grinding wheel 6, dresser 20, emery wheel length feed and correcting compensation mechanism (not shown) etc. on the grinding spindle longitudinal feed mechanism slide plate.
In illustrated this indent end face degree of depth Adaptive control apparatus, there is the measuring staff 8 of a non-magnetic material manufacturing to be arranged in the arbitrary radial section of workpiece, and in this plane, does the trace swing around the pivot pin 9 that is fixed on the work rest.Be provided with by the end of workpiece 5 one sides at measuring staff can stretch into excircle of workpiece positioning ring groove 19 in smoothly, also can with the design basis face 4 contacted metering contacts 7 of workpiece locating slot 19.For reducing its wearing and tearing, this metering contact 7 should adopt the material manufacturing of hard wear resistant.Also be provided with an energy on the measuring staff 8 it is imposed the extension spring 10 of ergometry, hanging over two hangs on the pin 11, one of them is hung pin and is fixed on the work rest of grinding machine, another is fixed on the measuring staff 8, so that 7 places maintain certain dynamometry at metering contact, press to the depth design datum level 4 of workpiece locating slot 19.Suitable position in measuring staff 8 swinging planes also is provided with the adjustable limiting screw 13 that limits the measuring staff amplitude of fluctuation, also is fixed on the work rest.At the other end annex of the measuring staff 8 relative with metering contact 7, also be provided with one and measuring staff be in the middle of the locating slot 19 and the electromagnet 15 (the electromagnet installation site is adjustable) that breaks away from the measuring position, be provided with a magnetic inductive block 14 at corresponding measuring staff position with it.Be provided with one at measuring staff opposite side on the other side and measure motion block 16, and being provided with a displacement sensing apparatus 17 and corresponding measuring instrument 18 in the position that adapts, the actual location groove locating surface 4 to bed-plate dimension Li (being called for short the high size Li of groove) that is used for workpiece to be machined 5 is measured.Measurement result is after instrument 18 is handled, deliver to emery wheel feed mechanism control system, with the high L0 of groove of standard relatively after, the instruction of sending compensation feeding ± fi realizes controlling the adaptation control grinding that this workpiece indent end face depth S i reaches standard depth S0 according to the variable quantity fi of the high size Li of groove.
Above-mentioned electromagnet 15 can impose and extension spring 10 active force opposite effect power measuring staff 8.The oscillating quantity of measuring staff 8 is by the positive stop on it 12 and be arranged on the measuring staff backhaul set screw 13 and electromagnet 15 engagement limits that are oppositely arranged that position-limiting action is played at the corresponding site place.In most of times of grinding working cycles, electromagnet 15 is always charged.When measuring staff 8 is sucked by electromagnet 15, the gauge head at metering contact 7 places will be positioned at the centre of positioning ring groove 19, not contact with the both sides of locating ring.At electromagnet 15 place ends, displacement transducer 17 and corresponding measuring instrument 18 are used to measure and the distance of 16 of measurement pieces that sensor 17 corresponding surfaces are very bright and clean.When workpiece is in the position of " material loading on earth " that locate on the anchor clamps, electromagnet 15 promptly cuts off the power supply, extension spring 10 pulls to the measuring position with measuring staff 8, measuring staff 8 contacts with the design basis face 4 of positioning ring groove 19 at measuring point 7 places, sensor 17 promptly begins to carry out the measurement to the high Li of workpiece 5 actual grooves, data to PLC of grinding machine (programmable controller) or the output of NC (numerical control) system, are sent the order to workpiece grinding and feeding measuring numerical value after instrument is handled.The measurement of 17 couples of high Li of groove of this sensor can be the measurement of contact, can be contactless measurement also, and shown in the figure is a kind of contactless measurement.
Its operation principle and process are: during grinding, grinding attachment is charged, and electromagnet 15 is also charged, and measuring staff is held, and the gauge head of measuring staff is positioned at the centre of positioning ring groove 19, does not contact with the both sides of groove, and workpiece is easy to enter the position location.When workpiece " material loading is on earth ", electromagnet 15 outages, extension spring 10 pulls to the measuring position with measuring staff 8, and measuring staff 8 contacts with the design basis face 4 of groove at metering contact 7 places, carries out the measurement of the high Li of actual groove by measuring transducer 17.If the Li that records is than the big fi of the high L0 of standard cell, the then actual amount of feeding that adds man-hour just should reduce fi; Otherwise than the little fi of the high L0 of standard cell, the actual amount of feeding that then adds man-hour should strengthen fi as if the Li that records.After measuring instrument is handled this measurement result, export PLC or NC feed system to, calculate the due adaptation of this workpiece control compensation amount of feeding bi=fi, again by numerical control feeding mechanisms such as stepper motor or servomotor by this adapt to control compensation amount of feeding-/+the grinding fast travel A of bi=fi and preset, predetermined grinding and feeding amount f0 sum (promptly press total feed amount=A+f0-/+fi) and preset program realization corase grind, correct grinding, tarry matter.After size reached projected depth value S0, grinding carriage returned automatically.When grinding attachment began feeding, electromagnet 15 was charged, and measuring staff 8 is held, and the measuring staff termination of measurement point 7 sides is positioned at the centre of positioning ring groove 19, and both sides can not contact, and broke away to measure.
Before carrying out above-mentioned grinding, at first should carry out the adjustment of grinding attachment, that is: with one the qualified workpiece of grinding the high L0 of groove and the indent end face depth dimensions S0 of this workpiece recorded in advance when shunting standard component usefulness.The grinding and feeding amount f0 that the vertical workbench total feed of emery wheel amount is set for quick feed A, according to the idle running of grinding allowance and needs and adjust amount of feeding bi=fi sum according to the adaptation control that the high Li of actual measurement groove judges automatically, promptly the vertical workbench total feed of emery wheel amount=A+f0-/+fi.After grinding attachment is adjusted, send the vertical workbench of emery wheel (A that realization is preset) fast to, crawl is handled stepper motor or servomotor again, is ground to bottom surface (judging as spark or sound) up to just, and the amount of feeding of this moment is the grinding and feeding amount f0 of standard.Measuring instrument is transferred to zero point (if S0 has error in a small amount, zero adjusting is also done corresponding change).After, during other parts of grinding, if the high Li of actual measurement groove of this workpiece to be ground than the high L0 height of groove (or low) of standard component bi=fi (as shown in the figure), control system will adapt to the variation of Li automatically, make the amount of feeding become A+f0-bi (or A+f0+bi) automatically, thereby guaranteed the accuracy of actual grinding depth S.
