Description

The square ram gantry machining center of high rigidity
Technical field
The present invention relates to a kind of gantry machining center, especially relate to the square ram gantry machining center of a kind of high rigidity.
Background technology
Numerical control gantry machining center, mainly consists of lathe bed, workbench, left and right pillar, crossbeam, saddle, main speed reduction box, console, electric control box and driving control device.Can complete the multistage manufacturing processes such as milling, brill, hinge, boring, be applicable to the Roughing and fine machining of the large and medium-sized part of every profession and trade.Chinese patent discloses a kind of numerical control gantry heavy-duty machine for machining, milling, boring, planing and grinding (publication number: CN 101502933A), it is comprised of lathe bed, carriage, composite pillar, crossbeam, back timber, rotary motive power head, chuck, tailstock, main drive gear, bistrique, milling and boring heads, planing frame, turning tool rest, electric control system etc.; Carriage is led by line slideway on lathe bed, and carriage is completed the reciprocating motion of carriage by main drive motor, main drive gear, gear, tooth bar, moves back and forth velocity interval: O.02-60000mm/min; Two composite pillars are connected with securing member respectively with lathe bed two sides; Back timber is connected with securing member with two composite pillar upper surfaces; Crossbeam is arranged on respectively on the guide rail of composite pillar both sides, utilizes two driven by servomotor of lifting one's head, and drives leading screw to rotate, thereby complete crossbeam, moves up and down; Milling and boring heads on crossbeam, turning tool rest are used respectively driven by servomotor, drive leading screw to rotate, and complete milling and boring heads, turning tool rest traverse feed; Bistrique on crossbeam, planing frame are used respectively driven by servomotor, drive leading screw to rotate, and complete bistrique, planing frame traverse feed; Bistrique on two composite pillars, planing frame are arranged on respectively on the guide rail of composite pillar, use respectively driven by servomotor, drive leading screw to rotate, and complete bistrique, the motion of planing frame bottom and top feed.But the ram gib of this lathe is generally the shapes such as T shape, because guide rail contact area is less, makes its rigidity poor, and service life is shorter.
Summary of the invention
The present invention is to provide the square ram gantry machining center of a kind of high rigidity, it is mainly that the ram gib that solves the existing lathe of prior art is generally the shapes such as T shape, because guide rail contact area is less, it is poor to cause contacting rigidity, service life shorter grade technical problem.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
The square ram gantry machining center of high rigidity of the present invention, comprise saddle, described saddle is provided with the square ram that can slide up and down, four faces of square ram are equipped with square guide rail, and square ram is connected with screw mandrel, and screw mandrel is connected with servomotor, ram is provided with main motor, main motor connects main shaft by transmission device, and main shaft top is provided with knife striking cylinder support, and knife striking cylinder support is provided with knife striking cylinder.The four sides of square ram is all provided with square rail, makes its contact area higher, and contact rigidity is stronger, thereby makes the rigidity of square ram stronger.
As preferably, the both sides of described saddle are provided with side gag, and the front portion of square ram is provided with front gag, and side gag, front gag are locked by gag latch segment.Side gag can play the effect of the square ram in location, thereby guarantees square ram movement ground smoothness.
As preferably, described square ram is provided with compensating cylinder, and it is more smooth and easy that compensating cylinder can guarantee that ram moves when moving up and down.
As preferably, described screw mandrel is provided with bearing, can make like this screw mandrel more smooth and easy rotationally.
