Abstract
The utility model relates to a vertical lifting work table of a pneumatic spring balanced milling machine. The utility model is composed of a machine column, a work table, a lifting table, a push rod of a pneumatic spring, a ball leading screw, a drive servomotor, a pneumatic spring and a machine base. The utility model has the advantages of high weight balancing precision, sensitive driving response, stable operation, high positioning precision, reduced driving servomotor power, electricity saving, extended service life of the motor, etc. The successful development of the utility model not only solves the essential technical problem existing in the original technology but also creates favorable conditions for development, popularization and application of the numerical control vertical milling machine.
Description
The utility model relates to a kind of pneumatic spring balance milling machine vertical lift workbench, belongs to the nC vertical milling machine Machining Technology for Cutting, is applicable to the weight balancing of nC vertical milling machine vertical lift workbench.
In traditional vertical knee-type milling machine vertical lift workbench,, can not counterpoise be set with counterweight to the self-powered platform of doing to move both vertically owing to be subjected to the restriction of its structure.Therefore, self-powered platform only does one can adjust clamping basal plane highly, only adjusts motion usually, mixes up back locking, and does not do feed motion, and vertical feed is provided by collar bush.
As everyone knows, the layout of vertical knee-type milling machine self-powered platform has unique advantage to processing middle-size and small-size part and mould class part, but exists a critical technical problem in this class lathe, promptly how to solve the weight balancing of numerical control vertical lift workbench.Because every feeding power transmission shaft of Digit Control Machine Tool must all be done the numerical control feed motion in total travel scope inside,, self-powered platform moved so can not only adjusting.Because the weight of self-powered platform is much larger than the cutting centripetal force, no matter be feeding up or down in cutting, always the feeding motor must be exported the weight that fortune is come the balance workbench greater than the required moment of cutting feeding.Therefore, just need select the used much bigger motor of feeding power of motor of other directions of feed of power ratio for use.Because the effect of gravity such as self-powered platform and workpiece makes ball screw be in stress all the time, can have a significant impact this service life to screw pair simultaneously.The self-powered platform product that adopts heavy-duty motor and two ball screw to drive is abroad arranged; but adopt this mode; must make motor often be in the full and down duty at work; not only to consume very big power; and can cause shorten dramatically the service life of motor; particularly the weight of self-powered platform will be come the towing astern motor by ball wire bar pair, causes when start and shutdown and produces instantaneous out-of-control phenomenon, and this is totally unfavorable to retrofit.
In order to solve the deficiency that original technology exists, the utility model provides a kind of pneumatic spring balance nC vertical milling machine vertical lift workbench.Its principal character is to adopt pneumatic spring balance lifting workbench weight, makes driving servomotor power reduce the instantaneous out-of-control phenomenon that occurs when successfully having overcome startup and shutdown greatly.
With embodiment and accompanying drawing structure is done concrete narration below.
Fig. 1 is traditional CNC milling machine vertical lift workbench schematic diagram
Fig. 2 is for adopting pneumatic spring balance nC vertical milling machine vertical lift Working table structure schematic diagram.
Among the figure 1, drive servomotor 2, column 3, workbench 4, lifting platform 5, ball screw 6, ball nut substrate 7, lathe base 8, pneumatic spring push rod 9, pneumatic spring
Traditional milling machine vertical lift workbench, its operation principle is, lifting platform 4 and column 2 are connected by guide rail, driving servomotor 1 is installed on the self-powered platform 4, by gear drive ball screw 5, fixedly the nut substrate 6 of ball screw is bearing on the lathe base 7, by the ball screw revolution self-powered platform is moved up and down.So the weight of all moving components adds clamp workpiece and cutting force all wants motor and ball wire bar pair to bear.
The utility model pneumatic spring balance milling machine vertical lift workbench is the weight that adopts pneumatic spring to come the balance lifting workbench, embodiment is, driving servomotor 1 is installed on the lathe base 7, connect (not shown) by synchronous cog belt with ball screw, ball nut (not shown on the figure) is adorned on the left lifting platform 4, and motor transmission ball screw drives self-powered platform by ball nut and moves up and down.Two pneumatic springs 9 are housed between workbench 3 and lathe base 7, the cylinder body of pneumatic spring is fixed on the lathe base 7, the push rod 8 of spring withstands self-powered platform, regulate the size of injecting the gas pressure intensity in the pneumatic spring, just can obtain required equilibrant force, self-powered platform is made accurate balance.
Adopt the main feature of the nC vertical milling machine vertical lifting work table of this kind new construction to be, lifting platform weight balancing precision height, transmission reflection is sensitive, working stability, positioning accuracy height, using electricity wisely, motor long service life and eliminated wink to out-of-control phenomenon. Succeeding in developing of this new structure both solved the guardian technique problem that original technology exists, and created advantage for the development of nC vertical milling machine and popularization and application again.
