Power head mechanism for single-arm boring machine tool upright post

Abstract

The invention discloses a power head mechanism for a single-arm boring machine tool upright post. In the power head mechanism, a guide rail is arranged and fixed in the inner side of a portal type upright post; a power head is arranged on the inner side of the portal type upright post through the guide rail; a power head adjusting motor is arranged on the upper part of the guide rail; a wheel shaft is arranged on the lower side of the adjusting motor; a main motor and the power head are arranged correctly; a worm gear speed reducer is arranged and fixed at the top end of the portal type upright post; one end of an adjusting lead screw is hinged with the power head, and the other end of the adjusting lead screw is connected with a screw thread in the middle of a worm wheel of the worm and gear speed reducer; and an upright post frame is arranged on the inner side of the wheel shaft, and is arranged above the base.

Description

technical field [0001] The invention relates to a power head mechanism for a column, in particular to a power head mechanism for a column of a single-arm boring machine tool, and belongs to the technical field of metal cutting machine tools. Background technique [0002] At present, in the structure of the column and the power head of the single-arm boring and milling machine at home and abroad, the structure of the cantilever is adopted. Since the power head is installed on the column in a cantilever manner, the power head itself has a certain weight. Huge cutting reaction force, so it is easy to reduce the geometric accuracy between the power head and the column, which not only reduces the service life of the machine tool, but also reduces the quality of the parts being processed. Contents of the invention [0003] The object of the present invention is to provide a power head mechanism for a column of a single-arm boring machine tool, which overcomes the above-mentioned...

AI Technical Summary

Problems solved by technology

[0005] Beneficial effects: the present invention adopts the column structure of the portal frame and installs the power head on the inner side of the column of the portal frame, so it can effectively overcome the power head mechanism of the column of the existing single-arm boring machine due to the adoption of the cantilever structure The geometric accuracy between the power head and the column caused by the method is easy to reduce, the service life of the machine tool is reduced, and the quality of the parts in processing is reduced.
