Moving mechanism of numerical control machine tool and lubricating method thereof

Abstract

The invention provides a moving mechanism of a numerical control machine tool. According to the technical scheme, the moving mechanism of the numerical control machine tool is characterized by comprising a workbench and a base; two stand columns capable of sliding along the base are arranged on the base; the stand columns are arranged on the base in a sliding mode through sliding mechanisms; the upper ends of the two stand columns are fixedly connected through a cross beam; sliding blocks capable of vertically sliding on the opposite inner side walls of the stand columns are arranged on the inner side walls of the two stand columns; a sliding base is fixed to one ends of the sliding blocks; the sliding base can axially move relative to the sliding blocks in the direction perpendicular to the axis of the base; a tool head is installed at the end, away from the sliding blocks, of the sliding base; a connecting beam is arranged on the side edge of the base; the connecting beam is connected with the bottoms of the two stand columns; andthe base is further provided with a lubricating mechanism used for adding lubricating liquid to the sliding mechanism. The moving mechanism has the beneficial effects that oil is automatically supplied for lubrication, the lubricating liquid is uniformly added, and the lubricating liquid can be switched for lubrication work.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a moving mechanism of a numerically controlled machine tool and a lubrication method thereof. Background technique [0002] A known mobile column milling machine comprises: a horizontal base anchored to the floor; a column support horizontally slidable along said base; a column structure supported by said support; a vertically slidable column structure along said column structure. a slide carrier; a slide seat horizontally slidable along the support in a direction perpendicular to the longitudinal axis of the base; and a spindle head mounted on the end of the slide seat and facing the worktable, the workpiece to be processed is fixed On the workbench; in order to respond to social development, the base is currently anchored in the pre-made pit on the floor of the room where the machine tool is installed, and the workbench is anchored on the floor parallel to the pit, which ...

Problems solved by technology

[0004] Second, the addition of lubricating fluid is not uniform enough, which will cause the column to tilt when moving. At the same time, in order to ensure that all parts are lubricated, a large amount of lubricating fluid is usually wasted, and most of the lubricating fluid is redundant. Generally, it is wasted and flowed out, which increases the cost ;

[0005] Third, there are many kinds of lubricating fluids, most of which will change their properties according to different environments such as temperature and humidity (for example, the demulsification ability of general lubricating oils and water-air contact will be reduced), and different types of lubricating fluids are used in different environments. There is an optimal choice, and the selection of lubricating fluids with different lubricating degrees can ensure the stable operation of the moving mechanism of the machine tool in the use time of the machine tool. Now it is troublesome to add different lubricating fluids, and the switching of lubricating fluids cannot be automatically realized, and different lubricating fluids cannot be guaranteed. Stable work under the use environment and working conditions
