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...

Problems solved by technology

However, in this way, there is not only a large burden in terms of cost, but also the problem that the thermal displacement caused by the generation of local temperature gradients caused by changes in the thermal environment cannot be substantially reduced fundamentally.
