Highly rigid complex machine

Abstract

The present invention relates to a highly rigid complex machine having a structure in which parts constituting a shaft are disposed adjacent to the central portion of a column to reduce rolling and pitching, and a stage is disposed on a saddle to improve rigidity. The highly rigid complex machine includes: a bed (400) on the top surface of which Z-axis guide ways (Z1, Z2) are formed in a lengthwise direction; a saddle (300) on which Y-axis guide ways (Y1, Y2) are formed in the front and rear directions perpendicular to the lengthwise direction, the bottom surface of the saddle (300) having a shape corresponding to that of the top surface of the bed (400) so as to be conveyed in the lengthwise direction of the bed (400); a column (100) on which X-axis guide ways (X1, X2) are formed in the vertical direction perpendicular to the length direction, the column (100) being disposed on the saddle (300) so as to be conveyed in the forward and rearward directions along the Y-axis guide ways (Y1, Y2); and a working shaft (200) disposed at a front side of the column (100) so as to ascend or descend along the X-axis guide ways (X1, X2). The Y-axis guide ways (Y1, Y2) are disposed at positions that are spaced a predetermined distance apart from a lower end of the column (100) in the upward direction.

Description

technical field [0001] Embodiments of the present invention relate to a composite processing machine, and more specifically, to a high-rigidity composite processing machine capable of reducing rolling and pitching by having a structure in which the shaft is brought close to the center of the column. ) and has a stepped structure at the saddle for increased rigidity. Background technique [0002] In general, a compound processing machine refers to a multi-spindle machine tool capable of both turning and milling, and can perform turning or milling depending on the type of tool attached to the spindle. [0003] This type of multi-function processing machine includes a three-axis linear transfer structure (X, Y, Z axis) and an axis (B axis) capable of tilting movement on the column in the height direction, and has a side for fixing the workpiece. Turning spindle. [0004] The driving method of the compound processing machine is divided into a ram moving method and a column mov...

Problems solved by technology

[0009] However, in the conventional column-moving type compound processing machine, the machining axis (200') is located above the column (100'), and when the column (100') is moved to the high center of gravity (G), rolling (horizontal shaking) occurs. , rolling) and pitching (up and down shaking, pitching), due to the long distance between the center of gravity (G) of the column (100') and the Y-axis guide rail (Y1', Y2'), there is a loop (loop, in a stable vibration Or the place where the displacement is the largest in the standing wave) the problem of weak rigidity

[0010] In addition, in the conventional column-moving multi-tasking machine, since the Z-axis saddle (300') of the plate structure is thinner than the structure on the column (100'), there may be a problem of low rigidity

In order to improve this, as shown in the figure, there is a design restriction that a plurality of, for example, three Z-axis guide rails (Z1', Z2', Z3') need to be provided.
