Work quenching hard gear, deformed so as to eliminate caused by heat treatment, obtain higher machining accuracy.Therefore, in high class gear system
In making, roll flute plays vital effect.
In roll flute processing, in addition to equipment, roller, emery wheel, the structure and precision of gear grinding tooling are to processing the accuracy of gear
Play a very important role.Traditional gear grinding tooling is more using end face as positioning datum, and the roll flute mandrel of centering is realized by endoporus, though
Right roll flute inner hole of workpiece and end face are all by Precision Machining, but it has certain franchise, and endoporus franchise will make the benchmark of gear
The centre of gyration of hole workbench does not repeat, and produces geometric eccentricity, so as to cause each tooth to be produced relative to datum hole skewness
Angular errors, influence teeth portion precision.
The content of the invention
The technical problems to be solved in the utility model is in view of the shortcomings of the prior art, to propose a kind of simple in construction, cost
It is low, positioning precision is high, versatility, the gear grinding clamp of guaranteed efficiency can be improved.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of gear grinding clamp, and it is special
Putting is：Roll flute mandrel including installing gear, it is provided with roll flute mandrel along 2 mills before and after roll flute mandrel axial directional distribution
Tooth station, the locating ring for being sleeved on and gear being positioned on roll flute mandrel is provided between front and rear 2 roll flute stations, the locating ring
Periphery is arranged to the positioning annular conical surface coordinated with bore, and the longitudinal cross-section for positioning annular conical surface is the low knot in the high both sides in centre
Structure；The positioning shaft shoulder for coordinating gear at roll flute station before positioning with locating ring, positioning shaft shoulder are provided with the front of preceding roll flute station
The cylindrical orientational cone-shaped surface being arranged to corresponding gear inner hole；The rear of roll flute station is provided with after described coordinates with locating ring
After positioning at roll flute station gear rear cone blocking, rear cone blocking is sleeved on roll flute mandrel, before being provided with locking at the rear of rear cone blocking
Afterwards at roll flute station gear locking device.
The technical problems to be solved in the utility model can also be realized further by the following technical programs, be bored after described
The cylindrical rear cone blocking conical surface for being arranged to coordinate with bore in one end of gear at stifled close rear roll flute station.
The technical problems to be solved in the utility model can also realize further by the following technical programs, the locking
Device is the locking nut being sleeved on roll flute mandrel, is provided with the rear end outer wall of roll flute mandrel and coordinates with locking nut screw thread
External screw thread.
The technical problems to be solved in the utility model can also be realized further by the following technical programs, in front and rear mill
The preset clearance for avoiding the teeth portion trueness error caused by franchise is provided between gear at tooth station.
Compared with prior art, the utility model is mainly by roll flute mandrel, locating ring, rear cone blocking and locking nut group
Into, fully rely on the conical surface positioning；During design between front and rear 2 gears preset clearance, permitting because of endoporus and end face can be avoided
Difference and caused by teeth portion trueness error, according to gear at preceding roll flute station is loaded into roll flute mandrel during clamping, load locating ring, then
Gear, rear cone blocking at rear roll flute station are respectively charged into, by clamping of workpieces on locking nut, finally loads lathe by overall, you can
Start roll flute operation.The utility model is simple in construction, positioning precision is high, manufacturing cost is low, versatility is high；Substantially increase life
Produce efficiency.
