Technical scheme of the present invention is: a kind of employing microcomputer is controlled, and is intended to grinding gear shaver emery wheel is realized on demand the device and the correction method of meticulous correction of the flank shape, and control section and operating part that this device is made up of microcomputer are formed.Described operating part includes the reduction gearing (12) (13) that is driven by stepper motor (7) and drives the generation transverse movement that leading screw (14) and nut (15) form (X to) mechanism, and amount of decrease lever (3) is gone up the lengthwise movement mechanism of on demand independently lengthwise movement of gold hand hay cutter fixing on the other end (2) do (Y to) by little compensation mechanism (4) on the slide unit (16) that joins together with nut (15), that drive with stepper motor (5); Two stepper motors (5) and (7) are to control interoperation respectively to realize the meticulous correction of the flank shape on demand of big flat-faced wheel do by the preset program of input microcomputer.
On the modification curve input mode, increase the error amount that shaving cutter tooth profile departs from given curve that is ground that will measure, imported microcomputer again.
Increase flat spring (30) on casing in the differential thread compensation mechanism (34) and the fine motion head (29), between gear wheel (21) and flat spring (30), increased helical spring (31).
Error is imported microcomputer compensate to improve the way of precision, concrete steps are:
The first step: at the modification curve of desirable (theory), the motion of control diamond pen repairs emery wheel, the grinding gear shaver.
Second step: accurately measure the modification curve of being taken turns at measuring room by roll flute, the modification curve that it and drawing are required relatively, taking-up is along the error amount of tooth depth direction each point.
The 3rd step: this error information is directly imported microcomputer, and after by microcomputer software error information and initial data suitably being superposeed, control grinding machine again gear shaver is carried out the grinding second time.
Fourth, fifth step: repeat two, three steps, general maximum as long as, can obtain very good gear shaver modification curve through 2-3 grinding.
The major advantage of the present invention and existing scheme comparison is: caught gear shaver grinding these characteristics of profiling quantity Y very little (being no more than 0.1mm) on big flat-faced wheel, propose little compensation mechanism (4) and amount of decrease lever (3) composite set on particular structure of the present invention-differential thread basis, thereby can realize high-precision correction of the flank shape simply; Adopt flat spring (30) to eliminate the differential thread gap in the little compensation mechanism of differential thread (4), helical spring (31) suppresses gear (21) torsional oscillation, has overcome the key of this class device accurate displacement control; The present invention has increased the error amount that shaving cutter tooth profile departs from given curve that is ground that will measure on the modification curve input mode, import the new mode of microcomputer again, through iterating processing, again flat-faced wheel is improved the correction of the flank shape of precision again.
Realize that a kind of preferred embodiments of the present invention such as accompanying drawing 1 are its schematic diagram, accompanying drawing 2 is the correction of the flank shape structure drawing of device, and this structure can be supporting with homemade big plane gear grinding machines, as long as take off the manual correction of the flank shape device of former lathe, change correction of the flank shape device of the present invention, just can come into operation.Accompanying drawing 3 is the detailed structure of the little compensation mechanism of differential thread.
