Description
Technical field
The utility model relates to a kind of five-axis vertical turn-milling complex machining center.
Background technology
Current machining center mainly contains T-type structure, anti-T-type structure, " case raising middle flask " structure and several form of back timber motion structure." case raising middle flask " structure obtains application in the structural design of high speed and precision five-axle linkage turn-milling complex machining center; this structure can guarantee the rigidity of lathe the best and the stability of precision; simultaneously by the weight of the parts that take in sail, obtain higher dynamic property and less energy requirements.
In addition, reduce lathe in mobile and in processing vibration is the technical barrier that Machine Tool design personnel make great efforts to solve always, and designer always considers there is larger breakthrough on machine tool structure.The gloomy essence mechanism of Japan does the designer of institute and engineer has from the beginning and predictably proposes, and in metal working system, makes its vibration source producing high vibration be all mainly configure from the basic structure of lathe own unreasonable.This be their correlation emphatically between each linear motion axis of research and analysis and cutting force be how to act on respectively fast with the machine tool motion component being transmitted to the large weight high rigidity that high-speed motion on after the conclusion that draws.They think, in process, driving force is not the center of gravity acting on movement parts very exactly, thus in high cutting speed especially under comparatively roughing feed velocity conditions, there is the trend producing twist motion, this inevitable twist motion and the effect of inertia due to motion generation, all can cause the vibration of lathe and make the machine element such as foundry goods such as lathe base or column bend and be out of shape.
Utility model content
The technical problem that the utility model solves overcomes the deficiencies in the prior art, thering is provided a kind of drives theory to combine with center of gravity " case raising middle flask " structure, the moving parts of Z axis and X-axis is configured between Y-axis two rhizoid thick stick, formed one desirable be but virtual center of gravity, produce and the five-axis vertical turn-milling complex machining center of actual driving force by the identical effect of center of gravity.
The technical solution adopted in the utility model is: five-axis vertical turn-milling complex machining center, column symmetry is arranged on base, each column is respectively installed with Y-axis leading screw and Y-axis guide rail, each Y-axis leading screw is respectively by a Y-axis driven by servomotor, Y-axis driven by servomotor Y-axis leading screw drives Y-axis slide plate to move along Y-axis guide rail as Y direction, X-axis guide rails assembling is in Y-axis slide plate, X-axis driven by servomotor X-axis leading screw drives X-axis slide plate to move along X-axis guide rail as X-axis, Z axis guide rails assembling is in X-axis slide plate, Z axis driven by servomotor Z axis leading screw drives Z axis ram to move along Z axis guide rail as Z axis.
X-axis slide plate is along X-axis side-to-side movement in motion framework Y-axis slide plate, and Y-axis slide plate drives X-axis slide plate to seesaw along Y-direction at leg surface, and Z axis ram is placed in X-axis slide plate and moves up and down.The mode that this layout adopts vertical columns and slide plate to combine, vertical columns has been connected main supporting role with base, realize the movement of each axle with the form of slide plate on vertical columns surface, both the enough rigidity supported had been ensured, reduce weight and the inertia force of movement parts simultaneously as far as possible, the size of required motor power (output) and driving member is also less, guarantees axially mobile fast simultaneously.
Relative to Y-axis slide plate, the less and driving force of X, Z axis slide plate quality acts on and connects paracentral position, therefore moves more steady; And Y-axis need carry the weight of X, Z axis in motion process, therefore its center of gravity constantly changes with the motion of X, Z axis; If Y-axis is single motor-driven structure, will produce pitching moment and deflection torque under the effect of driving force, under these two moment loadings, the movement locus of main axle cutter will there will be unpredictable distortion and vibration.In order to reduce the impact of this uncertain vibration on processing, driving based on center of gravity theoretical, proposing bilateral motor-driven structure.Bilateral motor-driven feature applies driving force in the bilateral symmetry of Y-axis slide plate, to reduce the impact driving the arm of force to produce as much as possible.Therefore, center of gravity drives and significantly can reduce the vibration of each axle in feeding transmission process, and finished surface chatter mark correspondingly will be made to reduce, and machining accuracy significantly improves, and due to the raising of acceleration of motion, also shortens non-process time.
The many employings of guide pass two line slideways of current Z axis ram or rail plate, guide rails assembling is at the left and right sides of ram or rear side, and its shortcoming conducts oneself with dignity due to ram and add to affect by cutting force man-hour, easily produces unbalance loading moment and distortion.The present invention adopts the layout of four line slideways then can overcome these shortcomings, thus keeps the stability of machining accuracy.
Z axis ram total length 1200mm, cantilever long generation vibration during for avoiding cutting, X-axis sled design length gets its half 600mm; On four guide rails of Z axis ram, every bar guide rail has two slide blocks, in order to be convenient to install, slide block is first arranged on a little connecting plate, then connecting plate is put together on the relevant position of X-axis slide plate together with slide block, after suitable for the adjustment of upper and lower two connecting plate positions, then the Z axis ram that guide rail is housed is slipped into X-axis slide plate along slide block.
Y-axis slide plate have employed the version of cavity stiffened panel, also add the bottom of arch and the design of Heightened lateral plate, has both met the requirement of part high rigidity and has alleviated the weight of parts to greatest extent.
The beneficial effects of the utility model are fabulous vibrations of producing when inhibit each axle to drive and bending, even if moving parts is when carrying out high-speed motion, center of gravity also can not change, thus achieves stable driving.Adopt frame-type structure simultaneously and gone out positioning precision through the sled design that finite element analysis is Weight-optimised and reach 0.007mm, repetitive positioning accuracy reaches 0.005mm, the quick translational speed of XYZ axle is 60m/min, and acceleration is the high speed and precision five-axle linkage turn-milling complex machining center lathe of 0.5g.
