Abstract

The utility model relates to a vertical machining centre which comprises a lathe bed, upright posts, a guide rail, a spindle box, a screw rod, a worktable and a slide saddle, wherein ribbed slabs in the upright posts adopt crisscrossed structures, and desanding holes are respectively arranged on the transversal cross-section of either upright post, and the crisscrossed ribbed slab structures are respectively symmetrically distributed on the lathe bed by using the screw rod as a center so as to increase transversal reinforced ribs. The utility model has good static and dynamic performance and high machining accuracy.

Description

Vertical machining centre

Affiliated technical field

The utility model relates to a kind of machining center, the vertical machining centre in particularly a kind of Digit Control Machine Tool field.

Background technology

Column and lathe bed are the important structure parts of machining center, and its architectural characteristic is very big to the performance impact of machining center.Be mainly reflected in aspects such as machining accuracy, vibration resistance, stock-removing efficiency, service life, therefore, quiet, the dynamic property of pillar construction is one of key factor of decision complete machine performance.Usually column basic structure is plate structure, is divided into inner floor and outside plate, and the floor on the outer wall does not have and is coupled to each other column hollow unbraced structure, poor rigidity, intrinsic frequency is low, and the lathe bed structure design is unreasonable, can cause insufficient rigidity, produce various distortion and vibration, machining accuracy is reduced.

Summary of the invention

In order to overcome above adverse effect, the utility model provides a kind of vertical machining centre, and this vertical machining centre has higher quiet, dynamic property, improves machining accuracy.

Technical solution of the present utility model is: lathe bed is supported by symmetrical six lower margins, column is fixed on the lathe bed, workbench is installed on the saddle, workbench by the X-axis motor-driven along the guide rail move left and right on the saddle, saddle is driven by y-axis motor, saddle and workbench integral body move forward and backward along the guide rail on the lathe bed, and main spindle box is driven by the Z spindle motor, and main spindle box moves up and down along the guide rail of column.

Its column inner rib plate of described vertical machining centre adopts crisscross structure, and the column lateral cross section is provided with the sand removal hole.

Its lathe bed of described vertical machining centre is symmetrically distributed with the rib structure that two row intersect with the Y-axis leading screw, and Outboard Sections increases horizontal ribs, and the edge is symmetrically distributed with the horizontal ribs of two row.

Adopting the beneficial effects of the utility model is to improve quiet, the dynamic property of machining center, improves the machining accuracy of machining center.
