Rib structure for the base of the turning center

Abstract

The present disclosure provides a bed for use with a turning center assembled with a main shaft housing in which a work piece is chucked, a turret and a tool table configured to process the work piece by a tool, and a transfer apparatus configured to transfer the turret and the tool table. The bed includes: a rib including a plurality of rib elements, in which the rib element includes a first rib element positioned at a lower portion of the bed where the main shaft housing is assembled, and a second rib element positioned at a lower portion of the bed where the transfer apparatus is assembled.

Description

technical field

[0001] This invention relates to machine tool bases, and more particularly, to the construction of base ribs (Ribs) for turning machining centers. Background technique

[0002] The base of the machine tool, especially the turning center, is made by casting, such as figure 1 As shown, a spindle frame 20 for clamping workpieces, a turret tool rest 40 and a tool table 50 for processing workpieces with tools are assembled on the upper part of the base 10, and a turret tool rest 40 and a tool table 50 for conveying the workpieces according to each axis (X, Y, Z) are assembled. Conveying system or conveying device 30 of turret 40 and tool table 50 .

[0003] In the case of a general machining center, the thermal displacement of the casting caused by the external temperature change can be controlled by real-time compensation due to its symmetrical structure, but as Figure 2a As shown, as far as the turning machining center is concerned, since the shape of the bas...
