Description

Numerical-control double-shaft rotary table

Technical field

This utility model is related to a kind of revolution equipment in Machine Manufacture field, more precisely, this utility model is related to And a kind of numerical-control double-shaft rotary table.

Background technology

Plain-milling machine only moves along the straight-line feed of tri- coordinate axess of X, Y and Z and is difficult to process complex space curved surfaces, even if The processing of simple spatial geometric shape is also required to carry out multiple clamping.To adapt to want higher and higher to processing and manufacturing technology Ask, occur in that five-axis linkage machine tools miscellaneous.It has been recognized that, five-shaft linkage numerical control machining center is for factory ship With complex-curved unique such as propeller, impeller, blade and heavy generator amature, large-sized diesel machine crankshaft and turbine rotor Means.

In practical application, install numerical-control double-shaft rotary table on CNC milling machine, vertical machining center additional, realize C The motion linkage of axle, the rotary feed campaign of A (B) axle and X, Y, Z axis straight-line feed, completes with cylinder, sphere, helicoid and answers The part processing of miscellaneous space curved surface, such as：Space cam profile, mold cavity etc.；Equation graduation or not is may be applicable to simultaneously The part processing of equation graduation structure, such as gear, ratchet, mouse tooth disk, gear clutch etc.；Can add with other coordinate linkages again The more complicated space curved surface of work, such as：Ship and wind stick etc.；It is installed on horizontal Machining centers, decapacitation is obtained Outside above-mentioned expanded function, using its accurate indexing function, achievable casing is once installed and completes the processing of five faces, is greatly enhanced The machining accuracy and working (machining) efficiency of box parts, obtains widely should in various electromotors, automobile gearbox production With.Its addition not merely ensure that machining accuracy, alleviate labor intensity, improves production efficiency, it is often more important that reduce Because of fixed assets invisible waste that the idleness of equipment is caused, avoid the substantial contribution produced because purchasing new machine input.With purchase Put new machine to compare, can typically save 60%～80% expense.

Now relatively conventional on Machine Tool Market is mechanical transmission-type numerical control rotating platform.

Workbench necessarily be in locking state when processing.But as its off-position is unrestricted, it is the same to be not as index dial, can only The integral multiple (5 °, 10 °, 15 ° etc.) of indexing fixed angle, and range of deflection is larger, it is impossible to using mechanical locking.Turntable The design of clipping variation mainly has pneumatic, hydraulic pressure and electromagnetic braking.Most design all adopts hydraulic clamp, because its pressure Height, reliable clamping, and five-axle number control machine tool necessarily have complete hydraulic system.But if using double-spindle numerical control turntable as common The supplement of Digit Control Machine Tool, is accomplished by individually being equipped with a Hydraulic Station using the turntable of hydraulic system, and this virtually increased cost.

Simultaneously because lathe of work level angle constantly changes, unbalance loading then occurs according to existing electromagnetic power-off brake and answers Situation of the iron core because of gravity pressure on friction plate when this loosens, causes friction plate inordinate wear, wastes the energy, affects workbench to ring Answer speed.
