Description
Technical field
It the utility model is related to Compositions of metal-working machines field, and in particular in a kind of new vertical compound five-axis robot that crouches
The heart.
Background technology
Current five-axle number control machine tool is broadly divided into following several：
1. cradle-type Five-axis NC Machining Center：Two rotary shafts（Turntable and cradle）, turntable is on cradle, the support of cradle both ends
On lathe base, three linear axis are all movement of the drive shaft around, upper and lower；
2. on the basis of gantry machining center, the swing of main shaft increase all around both direction, flame five are formed
Axle machining center；
3. installing a kind of universal two-axle rotating table additional on the vertical machining centre workbench of three axles, five axles can be formed（But
It is only applicable to miniature parts processing）.
But accordingly there is following defect in it：
1. cradle-type Five-axis NC Machining Center is the main flow structure of the Five-axis NC Machining Center of current standard, completeer in terms of function
Kind, available for the five-axis robot of middle-size and small-size complex parts, but cradle-type configuration aspects have the disadvantage that：
(1), cradle is integrated hanging, and part to be processed and rotary table are all on hanging cradle, and cradle
Both ends support from turntable center farther out, so being just doomed the Five-axis NC Machining Center of cradle-type from configuration aspects in weight butt face
Existing defects；
(2), main shaft needs to participate in the motion of three linear axis, relatively complexity, while such structure is also difficult to ensure that height
Rigidity；
(3), the processing pivot angle of cradle-type structure is swung by workbench to obtain completely, when pivot angle reaches ± 90 ° nearby
Very big tilting moment can be produced, tilting moment is bigger when workpiece is more big heavier, to the precision and stability of work pieces process all
Obvious influence can be produced；
(4), the cost of cradle-type Five-axis NC Machining Center is also higher.
2. flame Five-axis NC Machining Center needs to participate in the axial rotary motion of both direction due to main shaft so that ties on head
Structure is not only complicated but also enervated, simultaneously as reason in terms of head construction, spindle motor is difficult to realize big torsion, so flame
Five-axis NC Machining Center is typically only applicable to the high speed light cut of heavy parts；
3. the Five-axis NC Machining Center reequiped on the basis of three common shaft vertical machining centers, due to the original of configuration aspects
Cause, turntable diameter typically all in below 300mm, only adapt to the part of processing very little, can not solve five axles of medium-sized or above part
Processing.
To sum up, processed for appearance and size close to 300mm and the complex parts of the above, five axles of only cradle-type add at present
Work center is relatively adapted to, but cradle-type Five-axis NC Machining Center has that weaker, tilting moment the influence of rigidity, cost are higher etc. to be lacked again
Fall into.
