Portal vertical machining center

Abstract

The invention discloses a portal vertical machining center which comprises a lathe body, wherein a portal frame and a base are arranged on the lathe body; the portal frame spans the base; first guide rails in the horizontal direction, which are perpendicular to a plane where the portal frame is located, are arranged on the base; a working platform capable of making X-axis movement along the first guide rails is mounted on the first guide rails; second guide rails in the horizontal direction are arranged on a cross beam of the portal frame; a saddle capable of making Y-axis movement along the second guide rails is mounted on the second guide rails; third guide rails in the vertical direction, which are perpendicular to a plane where the working platform is located, are arranged on the saddle; and a spindle box capable of making Z-axis movement along the third guide rails is mounted on the third guide rails. The portal vertical machining center is good in rigidity and stability, and high in machining precision, and has very good market popularization prospects.

Description

technical field [0001] The invention relates to a machining center, in particular to a door-type vertical machining center. Background technique [0002] Such as figure 1 As shown, the current vertical machining center has a C-shaped structure, and the X and Y axes are installed together in the form of a cross slide. When the worktable moves left and right on the X-axis, due to the cantilever structure of the workbench 5, there will be a "seesaw" deformation ; When the workbench 5 is in different positions, deformation will occur because the line rail support positions of the Y axis are different; Excessive vibration will be generated during the process, which will affect the precision of processing and the smoothness of product surface. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a portal-type vertical machining center to achieve independent movement of the X and Y axes, the machining spindl...
