Existing lathe crushing radial feed motion i.e. U axle, V axle servomotor drags crushing slide plate 63, gold by ball-screw
Just roller motor 64 moves and realizes lathe crushing footpath motion i.e. V axle.
Lathe mass motion is: work pieces process must have X, Y, Z, B, C totally five numerical control s functions, and crushing is necessary
There are tri-numerical control axles of B, U, V.Therefore, lathe must have 7 effective numerical control axles.
In prior art, the C axle of numerical control worm gear-grinding machine bed generally uses C axle servomotor by reducing gear band
Dynamic work spindle rotates.
Above-mentioned gear grinding machines have following defects that
1, machine tool structure is complicated, and part is many, manufactures and assembly difficulty is big, and difficult adjustment is easily broken down.
2, workpiece spindle C through-drive chain length, driving error is big；When engaging due to gear, produce vibration, affect work pieces process
Surface roughness.
3, lathe at least needs seven effective numerical control axles, and product cost is high, expensive, adds financial burden to enterprise.
At present, along with the fast development of gear industry, user is in the urgent need to not only economy but also practical gear grinding product.
Summary of the invention

Wheel dressing mechanism, including longitudinal slide, equipped with cross slide on longitudinal slide；Emery wheel case is fixedly mounted on cross slide；Sand
The emery wheel of roller box is driven to B axle spindle servo electric machine；
Longitudinal slide is arranged on lathe bed by radially ball-screw, and radially ball-screw is by X-axis driven by servomotor, it is achieved vertical
Move in radial direction i.e. X-axis to slide plate, cross slide, emery wheel case；
Cross slide is arranged on longitudinal slide by tangential ball-screw, and tangential ball-screw is by Y-axis driven by servomotor, it is achieved
Longitudinal slide, cross slide, emery wheel case move in tangential i.e. Y-axis；
Emery wheel motor is arranged on lathe bed.
The workpiece rotary shaft of work rest connects C axle torque motor.
The numerical control worm gear-grinding machine bed that the present invention provides, compact and reasonable, processing is accurate, precision is high, makes lathe by existing
Seven the numerical control axles having technology are reduced to five numerical control axles.The C axle of slide type work rest gear grinding machine with worm grinding wheel is designed with
Torque motor directly drives the version of work spindle, cancels and uses servomotor, reducing gear, workpiece master in prior art
