Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, a kind of novel high-precision numerical control lathe grinding building-block machine is provided, comprise headstock, main spindle box, workpiece chuck, lathe bed, tailstock centre and grinding spindle assembly, wherein: also comprise the turning main shaft being formed by hydraulic static spindle, be arranged in main spindle box, with the grinding spindle being formed by fluid pressure grinding spindle, be arranged in grinding spindle case.
A kind of the utility model high precision numerical control car mill building-block machine, wherein: main spindle box comprises off-load belt pulley, bearing, bearing block, protecgulum, the shaft shoulder, hydraulic static spindle, rack sleeve, static-pressure oil chamber successively, wherein off-load belt pulley engages by bearing with bearing block, at bearing block other end protecgulum, by the shaft shoulder, hydraulic static spindle sleeve is coordinated with bearing block, hydraulic static spindle runs through and is arranged on wherein, and static-pressure oil chamber coordinates with hydraulic static spindle and rack sleeve.
The utility model high precision numerical control car mill building-block machine, wherein: in bearing block, be also provided with encoder.
A kind of the utility model high precision numerical control car mill building-block machine, wherein grinding spindle assembly comprises wheel guard, emery wheel, grinding axle protecgulum, dynamic and static pressure oil pocket, grinding spindle sleeve, fluid pressure grinding spindle successively, wheel guard and emery wheel coordinate with grinding spindle sleeve by grinding axle protecgulum, fluid pressure grinding spindle runs through wherein, drives emery wheel rotation.
The utility model high precision numerical control car mill building-block machine, owing to having adopted above technical scheme, makes it compared with prior art, has following advantage and disadvantage:
1, machining accuracy improves
Because turning main shaft has used hydraulic static spindle in this car mill building-block machine, the machining accuracy of part is greatly improved, use the turning machining accuracy of common rolling bearing main shaft to be generally 0.03-0.06mm, use the turning machining accuracy of hydraulic static spindle to be generally 0.01-0.03mm.
2, working (machining) efficiency improves
For needs, modified or other heat treated workpiece, need not dismantle workpiece, again be installed, and after turning, can complete grinding, can once reach modified front required state, has saved like this dismounting centering operation one, has saved a lot of process times.
3, fineness improves
The fineness of workpiece also can improve along with the change of turning main shaft.
4, stability
Turning and grinding spindle have been used fluid pressure, dynamic and hydrostatic bearing to make the part quality processing have good stability, because be no matter common rolling bearing in headstock or " the three slices watts " bearing in bistrique, capital is along with the increase of service time, and main shaft precision is along with reduction.Therefore, the utility model is in conjunction with the technical characterstic of self, popular high precision numerical control car mill universal machine tools have been developed, its high precision numerical control car mill universal machine tools can clamped one time complete separately whole operations of lathe and grinding machine, comprise turning curved surfaces, cutted thread, the basic demand of some lathes such as the grinding conical surface and cylindrical grinder, makes operating personnel use the method for operating of original lathe need not train direct control and uses.
