The purpose of this utility model is to overcome the deficiencies in the prior art, provides the economical dynamic pillar high-speed machining center that a kind of structure is simple, with low cost, fabrication cycle is short and stable and reliable in work.
For achieving the above object, technical scheme provided by the utility model is:A kind of economical dynamic pillar high-speed machining center, include bed piece, process head and tool magazine it is characterised in that:Also include the workbench for placing processing workpiece, multiple support bases for installing described workbench being arranged side by side positioned at described bed piece side, saddle on described bed piece, for the first order drive component driving described saddle to move back and forth along bed piece X-direction, constitute the column that Y direction moves back and forth with described saddle, for drive the second level drive component that this column moves back and forth along Y direction and be arranged between described column and processing head in vertical direction arrangement Z-direction slide rail, wherein said processing head is passed through this Z-direction slide rail and is connected with the lifting moving of described column composition vertical direction.
Preferably, described first order drive component is included for driving the ball-screw that described saddle moves back and forth along X-direction, for driving the X-axis servo drive motor of this ball screw turns and being arranged at the shaft coupling between this ball-screw and X-axis servomotor.
Preferably, described second level drive component is included for driving the ball-screw that described column moves back and forth along Y direction, for driving the Y-axis servomotor of this ball screw turns and being arranged at the shaft coupling between this ball-screw and Y-axis servomotor.
Further, multiple described support bases are integrated moulding by casting with described bed piece and are made, and plurality of described support base is evenly arranged along this bed piece side length direction.
Further, its upper surface of described bed piece is provided through in the mounting groove at its length direction two ends.
Compared with prior art,This programme includes bed piece by adopting、Processing head and tool magazine,Also include the workbench for placing processing workpiece、Multiple support bases for installment work platform being arranged side by side positioned at bed piece side、Saddle on bed piece、For the first order drive component driving saddle to move back and forth along bed piece X-direction、Constitute the column that Y direction moves back and forth with saddle、For drive the second level drive component that this column moves back and forth along Y direction and be arranged between column and processing head in vertical direction arrangement Z-direction slide rail,Wherein processing head passes through the version that this Z-direction slide rail is connected with the lifting moving of column composition vertical direction,Machining center using this kind of version,During work, processing head can be along bed piece X-direction、Y direction and Z-direction realize 3 D auto motion,Such that it is able to rapidly realize the parts to be processed on workbench is carried out with the processing operation of fast and stable;Additionally due to bed piece body is integrated cast being made, on the one hand it not only can reduce difficulty of processing and processing cost, and material cost is substantially reduced, and whole cost can reduce by 50% about;On the other hand with respect to traditional split-type structural, it possesses more firm excellent rigid, and then can guarantee that lathe possesses more excellent machining accuracy and quality in process.

Specific embodiment
With reference to specific embodiment, the utility model is described in further detail:
Referring to shown in accompanying drawing 1 to 3, the economical dynamic pillar high-speed machining center of the one kind described in the present embodiment, it includes bed piece 1, processing head 6, tool magazine(In figure is not shown), for placing the workbench 3 of processing workpiece, multiple support bases 2 for installment work platform 3 being arranged side by side positioned at bed piece 1 side, saddle 4 on bed piece 1, for the first order drive component driving saddle 4 to move back and forth along bed piece X-direction, constitute the column 5 that Y direction moves back and forth with saddle 4, for drive the second level drive component that this column 5 moves back and forth along Y direction and be arranged between column 5 and processing head 6 in vertical direction arrangement Z-direction slide rail 10, wherein processing head 6 is connected by the lifting moving that this Z-direction slide rail 10 constitutes vertical direction with column 5.
Above-mentioned first order drive component in the present embodiment is included for driving the ball-screw 7 that saddle 4 moves back and forth along X-direction, for driving the X-axis servo drive motor 8 that this ball-screw 7 rotates and being arranged at the shaft coupling 9 between this ball-screw 7 and X-axis servomotor 8.Work book, X-axis servo drive motor 8 directly drives ball-screw 7 to work by shaft coupling 9, realizes direct connection action, to ensure to possess rigidity just and stability.Equally, the above-mentioned second level drive component in the present embodiment is included for driving the ball-screw that column 5 moves back and forth along Y direction, for driving the Y-axis servomotor 11 of this ball screw turns and being arranged at the shaft coupling between this ball-screw and Y-axis servomotor 11.
Finally, in order to reduce the difficulty of processing of whole lathe, mitigate workman's manufacture installation exercise labor intensity and reduce enterprise's production capacity further, multiple above-mentioned support base in this programme is integrated moulding by casting with bed piece and is made, and plurality of support base is evenly arranged along this bed piece side length direction;Simultaneously in order to ensure whole machining center structure compacter and mitigate lathe bed own wt, its upper surface of above-mentioned bed piece in the present embodiment is provided through in the mounting groove at its length direction two ends.
During work, saddle moves back and forth in the promotion lower edge bed piece X-direction of X-axis servomotor, column can move back and forth in the promotion lower edge Y direction in Y-axis servomotor simultaneously, same processing head can move along the Z-direction slide rail on column along Z-direction vertical lifting, so that realize machine work head work when X, Y and Z-direction three-dimensional motion, realize to processing workpiece processing operation.
The examples of implementation of the above are only the preferred embodiment of this utility model, not limit practical range of the present utility model with this, therefore the change that all shapes according to this utility model, principle are made, all should cover in protection domain of the present utility model.
