Large vertical high-speed numerical-control lathe saddle system

Abstract

The invention discloses a large vertical high-speed numerical-control lathe saddle system which comprises a transverse beam, a ram, a slide base and a saddle. A transverse linear guide rail and a transverse grating scale are arranged on the transverse beam, and the slide base is arranged on the transverse beam via a slide base ball screw and is connected with the transverse linear guide rail; a vertical linear guide rail and a vertical grating scale are arranged on the slide base, and the ram is arranged on the slide base via a ram ball screw and is connected with the vertical linear guide rail; the saddle is arranged at the lower end of the ram. The large vertical high-speed numerical-control lathe saddle system has the advantages that the slide base is connected with the transverse beam by the corresponding linear guide rail, the ram is connected with the slide base by the corresponding linear guide rail, accordingly, horizontal and vertical movement speeds of the slide base and the ram can be obviously increased under a no-load condition, and the work efficiency of a lathe can be obviously improved.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a tool post system for a numerically controlled lathe, in particular to a tool post system for a large vertical high-speed numerically controlled lathe. Background technique [0002] At present, the tool holder system of large vertical CNC lathes with a working surface of 3.15 meters is mostly a hard rail structure, that is, the upper and lower, left and right guide rails are all driven by trapezoidal screw, which not only has the problems of many parts and complex structure; at the same time, the space The shortcoming of the knife moving up and down and left and right is slow, which affects the working efficiency of the whole machine, and the precision of the displacement is low. Contents of the invention [0003] The object of the present invention is to provide a large vertical numerical control lathe tool post system with fast up and down, left and right displacement sp...
