Background technology
At present, in the keyway of processing disk class helical gear inner hole of workpiece, a lot of customer requirement key slot center and tooth end-tooth
Groove center has alignment requirements.
Prior art is generally assisted using wire cutting after line or using length bar, wire cutting two behind centering center
Individual method；Process after 1 line, due to be artificial measure on beveled gear teeth end face after rule, error is larger it is adaptable to precision will
Seek not high occasion, and when producing in batches, there is no uniformity；2 are placed in teeth groove using 2 length bars and (are separated by 8- between 2 length bars
10 teeth groove), molybdenum filament asks teeth groove center, workpiece pressing, wire cutting keyway by length bar external diameter；The method high precision, but due to every
It is required for repeatedly adjusting to center before individual part processing, therefore efficiency is very low.
Content of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thus providing a kind of helical teeth end-tooth groove center to tooth
Cut groove frock, ensure that key slot center is alignd with helical teeth end-tooth groove center it is ensured that the form and position tolerance satisfaction requirement of keyway is same
Shi Tigao working (machining) efficiency.
The technical scheme providing according to this utility model, helical teeth end-tooth groove center cuts groove frock and includes base plate, core to tooth
Axle and locating piece, is characterized in that: mandrel bottom is fixed on base plate, are provided with changeover portion, core in the middle part of mandrel and mandrel bottom between
The changeover portion upper end of axle is provided with locating surface, and the changeover portion lower end of mandrel is provided with lower locating surface；Base plate side is provided with locating piece and slides
Groove, locating piece chute is slidably connected locating piece.
Further, mandrel top is provided with top board clamp nut and top board, and top board clamp nut is by top board pressure
Clamping of workpieces.
Further, mandrel lower end is provided with lower platen, and lower platen connects lower platen fastening bolt, lower platen fastening bolt
Connecting mandrel lower end, thus compressed mandrel lower end by lower platen.
Further, locating piece front end is provided with the positioning boss agreeing with disk class helical gear workpiece phase.
Compared with the prior art this utility model has the advantage that
This utility model structure is simple, compact, reasonable, simple to operate, and the clamping time is short, can effectively, reliably position
Workpiece, greatly improves the stability of crudy；Ensure that key slot center is alignd it is ensured that keyway with helical teeth end-tooth groove center
Form and position tolerance meet require simultaneously improve working (machining) efficiency；The workpiece hole location causing of walking about can effectively be eliminated unqualified.
