Abstract

The invention relates to a tool rest mechanism of a large-scale vertical lathe. A supporting seat is fixed on a top end face of a carriage sliding table; an upper bearing seat assembly is arranged on the supporting seat; a lower bearing seat assembly is arranged on the carriage sliding table; a ball screw rotates between the upper bearing seat assembly and the lower bearing seat assembly; a screwnut is connected to the ball screw through threads; a cover plate is fixedly arranged on one side of the carriage sliding table; an adjustment cushion block is arranged between the cover plate and the carriage sliding table; the section of a ram is in a polygonal shape; each top angle in the polygonal section is an obtuse angle; the polygonal section has at least two parallel edges; the adjustment cushion block is positioned on the side wall of the ram which corresponds to the two parallel edges in the section; a lathe tool seat is fixed at the bottom of the ram; a smart seat is fixed at the top of the ram; and the ram is fixedly connected with the screw nut into a whole. The tool rest mechanism of the large-scale vertical lathe has the advantages of simple structure, convenience for assembly, low processing cost, convenience for adjustment and the like.

Description

technical field [0001] The invention relates to a part for the up and down movement of a turning tool of a large vertical lathe used for processing large-diameter rings, flanges or forgings, in particular to a tool holder mechanism for a large vertical lathe. Background technique [0002] In the existing technology, the tool post of large vertical lathe generally adopts a square ram, and the gap between the ram and the sliding table is controlled by using inclined iron, which has high processing cost, relatively complicated structure, and high assembly requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a large vertical lathe tool holder mechanism with simple structure, convenient assembly, low processing cost and easy adjustment. [0004] According to the technical solution provided by the present invention, the large-scale vertical lathe tool holder mechanism includes a suppor...
