Embodiment 1：As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, a kind of high accuracy straight-tooth mouse tooth disk grinding processing method is main
If solving the problems, such as mouse tooth disk (a set of) installation base surface parallel accuracy, lathe assembly precision is met.To process our unit's part：
As a example by 20LH91404 (144 tooth) mouse tooth disk Fig. 1：
To in the case where existing equipment is constant, only small change need to be carried out to program, you can the processing of lifting mouse tooth disk
Precision.
Machine tool system used in the present invention is SIEMENS 840D, and most of program that lathe is used is modularization journey
Sequence is as shown in figs. 6-9.The procedure that the present invention is used is combined and key parameter is entered by each modular program
Row research sets and obtains.
Wherein indexing cycles subprogram is briefly discussed below：
It is as follows on determining roll flute loop parameter setting of the invention and step：
Step 1, the opening main program page, then selection indexing subprogram opening is (see Fig. 6 circleds)；
Step 2, opening index subprogram (see Fig. 7) and then make 87.5 ° into by the 2.5 of circled, see Fig. 8.Because of 144 tooth/4
35 teeth groove or 37 grooves near at=36 teeth, therefore selection fluted disc a quarter meet this " across tooth grinding " and set across the number of teeth
Meter, and checking computations 144/35 and 144/37 without it is not divided evenly and across the number of teeth except Teeth Number is irreducible fraction in lowest term, therefore energy
The enough processing for realizing this " across tooth grinding ".Succeeded through overtesting processing.
Step 3, crushing：Emery wheel number of times will be repaired in last Grinding Cycle Command to be changed to every 144 or repaiied more than 144
Whole once emery wheel once completes grinding with teeth, and midway is not repaired；
Advantage processing object：The multiple tooth mouse tooth disks such as 144 teeth, 360 teeth, 720 teeth.
The like the selection of 360 tooth mouse tooth disks across the number of teeth be 89 (89 °) 91 (91 °), and can be for 720 tooth mouse tooth disks
On the basis of 360 tooth mouse tooth disks, two groups of circulations are selected, simply the initial position at second group adds 0.5 ° to see Fig. 9, will repair emery wheel
Number of times is changed to every 720 or is repaired once more than 720.
Across across the number of teeth position necessary requirement of tooth grinding：It is positive integer across the number of teeth, meeting fluted disc will grind one week, total number of teeth
Do not divided exactly across the number of teeth.(across number of teeth position can be regarded as tooth slot position, because during grinding, it is processing that tooth slot position angle is set up
Benchmark zero point).Such as the fluted disc of 144 teeth, selection is 35 across the number of teeth, then 144/35=4.1142 ..., and quotient meets condition, and 144/
35=32×24/ 5 × 7 is irreducible fraction in lowest term, can be selected.
Main Basiss：Abrasion of grinding wheel error averaging, dispersion reduce grinding heat, reduce the influence of Machine Tool Positioning Accuracy error.
Step 4, the selection of across number of teeth size：In basic 90 ° of selection is nearby interval because the most frequently used 0 ° of lathe, 90 °, 180 °,
270 ° of four positions, dispersion emery wheel loss error is appropriate and easily controllable, when upper and lower a pair of fluted discs initial angle differs 45 ° of assemblings
When, mutually make up height best results.
Step 5, the selection of last grinding allowance：0.01~0.015, formulating rules：Consider that emery wheel quality and grinding type face are protected
Holding property and the loss for completing Grinding Cycle Command, that is, be ground still effective during last tooth；
Step 6, program application：Grinding is applied to numerically control grinder, when slot grinding (tooth) subprogram of grinding program is to use
When macroprogram is indexed, across tooth angle degree needed for only adjacent teeth angle degree need to be changed to, such as：The fluted disc of 360 teeth is adjacent
Tooth angle degree is " 1 ° ", then across tooth angle degree can be changed to " 89 ° " or " 91 ° "；
Step 7, for the processing of 720 tooth mouse tooth disks, selection class time 360 tooth mouse tooth disk processing methods, simply using Two-way Cycle,
It is i.e. constant across the number of teeth, when second circulation is entered, initial angle is changed into 0.5 °；
Step 8, in last circulation grinding, lathe only has three feed shafts of Rotary indexing movement of Y-axis and X-axis and B axle
Motion, the motor point position of Y-axis and X-axis is all repeatedly cycling motion, and grinding status is fixed, and disturbing factor is few, therefore can be improved
Working position precision, the grinding tool track of tooth is shown in Fig. 3 and Fig. 4.
Macroprogram usage is illustrated:
Example 1, process 60 tooth mouse tooth disks in Japanese big machine test of snuggling up to, tooth form as shown in fig. 2, upper fluted disc 2 and lower tooth
Disk 3 is connected, examination selection：During across number of teeth 60/4+1=16 (tooth), 60/16=3.75 does not have divided evenly, but is not fraction in lowest term, no
Meet across tooth grinding condition.If selection：60/4+2=17 (tooth), 60/17=3.52941 ..., and be fraction in lowest term, meet bar
Part, can select.The position angle for calculating the 17th tooth is 102 °.If first teeth groove is programmed for workpiece coordinate system B axle zero point.
Here is the brief example explanation of Siemens System program of jumping division：
Subprogram：
Above is for some procedures experiment that is feasible and being carried out in other lathes is processed in checking " across tooth " of the invention.
So during establishment macroprogram, the number of teeth situation according to other mouse tooth disks only needs setup parameter：
1), initial angle,
2), across tooth angle degree,
3), the initial number of counter,
4), count and judge setting value,
Without regrouping a cycle criterion program again, a processing feeding subprogram is simply worked out according to bottom land path
Achieve that new across tooth Grinding Cycle Command processing.
As described above, embodiments of the invention are explained, but as long as essentially without this hair of disengaging
Bright inventive point and effect can have many deformations, and this will be readily apparent to persons skilled in the art.Therefore, this
The variation of sample is also integrally incorporated within protection scope of the present invention.
