Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but it should not be understood that the scope of the subject matter of the present invention is limited to the following embodiments. Without departing from the above-mentioned technical idea of ​​the present invention, various replacements and changes made according to common technical knowledge and customary means in this field shall be included in the scope of the present invention.

[0027] A circular guide rail processing method for remanufacturing a cantilever beam stiffness compensation device for heavy-duty machine tools. The heavy-duty machine tool that needs to be installed with a cantilever beam stiffness compensation device mainly includes a main column 7, a cantilever beam 8, a lower support frame 10 and an upper support frame 5. The main column 7 is installed perpendicular to the ground, and its upper and lower ends are connected to the rota...

Abstract

The invention provides a method for processing an arc guide rail which is applied to a stiffness compensation device for a remanufactured cantilever beam of a heavy-duty machine, and particularly relates to a method for processing the arc guide rail of the stiffness compensation device for the remanufactured cantilever beam of the heavy-duty machine. The method includes that 1) a blank of the arc guide rail is mounted on a supporting platform of the heavy-duty machine; and 2) a turning tool is mounted on a tool rest, and driven to move circularly by firstly adjusting positions of the tool rest and / or the turning tool and secondly adjusting a rotating main column so as to turn the upper surface, the inner surface and the outer surface of the blank of the arc guide rail.

Description

technical field [0001] The invention relates to the field of heavy-duty machine tool manufacturing, in particular to the component manufacturing of heavy-duty machine tools for processing large ring-shaped parts and having a cantilever beam structure. Background technique [0002] As a machine for processing various large and super-large parts, heavy-duty machine tools occupy an important position in industries such as energy, transportation, machinery, and aerospace. Because the existing heavy-duty machine tool is bulky and usually weighs tens of tons or even hundreds of tons, there must be weak links in its structure (such as the cantilever beam itself with large weight and size, and its connection with the column, etc.). Furthermore, the lightweight design of heavy-duty machine tools is the goal that experts and technicians in this field have been pursuing. It is worth emphasizing that while designers are pursuing the lightweight of heavy-duty machine tools, the problems...
