Abstract
The utility model provides a kind of grinding machine micro-feeding device, can solve the technical problem of existing micro-feeding device stability difference.It includes lever, eccentric bushing and driving mechanism, and eccentric bushing is socketed on main shaft and is arranged with spindle eccentricity, and main shaft connects grinding wheel, it is characterised in that：Lever includes core bar and sleeve, and sleeve is socketed on core bar, and core bar is fixedly connected with eccentric bushing, and driving mechanism includes motor and ball wire bar pair, and the nut of the lead screw rotation of motor driven ball screw pair, ball wire bar pair passes through shaft and the rotation connection of sleeve one end.The rigidity of structure is high, and stability is good, and the lever arm length that core bar and sleeve are constituted, and grinding wheel eccentricity amount is small, it can be achieved that precise controlling；And the setting of weight is avoided, electric motor starting is more convenient.
Description
Technical field
The utility model is related to grinding machine fields, are especially specifically related to a kind of grinding machine micro-feeding device.
Background technology
The micro-feeding device of existing grinding machine includes lever, eccentric bushing and driving mechanism, and lever is overlapped on fulcrum and passes through
Load-carrying is hammered into shape to eliminate the gap between lever and fulcrum, and the both ends of lever abut eccentric bushing and the output end of driving mechanism respectively,
Eccentric bushing is socketed on main shaft and is arranged with spindle eccentricity, and driving mechanism activation lever is rotated around fulcrum, lever drives eccentric bushing
Beat, to driving spindle and the grinding wheel being installed on main shaft feeding.Since grinding force and weight power imbalance are easy to cause
Lever tilt, security performance is poor, and weight be arranged overweight then driving mechanism startup it is very difficult.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of grinding machine micro-feeding device, existing Fine Feed can be solved
The technical problem of device stability difference.
Its technical solution is such comprising lever, eccentric bushing and driving mechanism, the eccentric bushing are socketed on main shaft
And be arranged with spindle eccentricity, the main shaft connects grinding wheel, it is characterised in that：The lever includes core bar and sleeve, the sleeve
It is socketed on the core bar, the core bar is fixedly connected with the eccentric bushing, and the driving mechanism includes motor and ball wire bar pair,
The motor drives the lead screw of the ball wire bar pair to rotate, and the nut of the ball wire bar pair passes through shaft and the sleeve one
End rotation connection.
Further, described sleeve one end is fixed with beat seat, and the beat seat passes through the shaft and the ball wire
The nut rotation of bar pair connects.
Further, coordinated by linear bearing between the sleeve and the core bar.
Further, the screw both end of the ball wire bar pair is respectively by bearing support in lathe bed.
Further, the motor is servo motor and connects the lead screw by synchronous belt deceleration mechanism.
Further, the micro-feeding device further includes grating scale, and the measurement end of the grating scale is socketed on the ball
The nut of screw pair.
The micro-feeding device of the utility model, lever include core bar and sleeve, and sleeve is socketed on core bar, core bar and eccentric bushing
It is fixedly connected, sleeve one end is connected by the nut rotation of shaft and ball wire bar pair, is moved down on the nut of ball wire bar pair
Dynamic band moving sleeve and core bar are swung, and to driving spindle and the grinding wheel being installed on main shaft feeding, the rigidity of structure is high, stablizes
Property it is good, and the lever arm length that core bar and sleeve are constituted, grinding wheel eccentricity amount are small, it can be achieved that precise controlling；And avoid weight
Setting, electric motor starting is more convenient.
