Numerical control rocker arm drilling machine

Abstract

The invention provides a numerical control rocker arm drilling machine, belonging to the field of processing machinery. The technical scheme of the invention is as follows: the invention comprises a stand column, a rocker arm which is installed on the stand column, and a main shaft box which is installed on the rocker arm and a base which is fixedly connected with the bottom part of the stand column; a numerical control drive assembly is arranged between the main shaft box and the rocker arm, and the main shaft box moves along the rocker arm in the numerical drive assembly; the main shaft is provided with the numerical control drive assembly for main shaft speed change and feed; the rocker arm is provided with the numerical control drive assembly for the swinging of the rocker arm. The technical scheme can be realized by reforming current rocker arm drilling machine, and can be realized so long as adopting the structure of inner columns and outer columns; therefore, a high-quality numerical control device can be built by spending a small amount of expenses, thus the promotional value thereof can be imaginable.

Description

technical field [0001] The invention relates to a numerical control radial drilling machine, in particular to a numerical control radial drilling machine in which the movement of the main shaft box, the speed change of the main shaft, the feed and the swing of the rocker arm all adopt numerical control. Background technique [0002] The prior art closest to the present invention is a utility model patent with the notification number CN2810827Y, which discloses a technical scheme of a numerically controlled radial drilling machine with a numerically controlled spindle feed and a numerically controlled workbench that moves horizontally and vertically. Compared with the traditional technical solution, it has the advantage of higher machining accuracy. However, because it relies on the horizontal and vertical movement of the worktable to realize the processing of large workpieces, there is a problem that the processing of large workpieces cannot be realized only by the horizontal...

[0002] The prior art closest to the present invention is a utility model patent with the notification number CN2810827Y, which discloses a technical scheme of a numerically controlled radial drilling machine with a numerically controlled spindle feed and a numerically controlled workbench that moves horizontally and vertically. Compared with the traditional technical solution, it has the advantage of higher machining accuracy. However, because it relies on the horizontal and vertical movement of the worktable to realize the processing of large workpieces, there is a problem that the processing of large workpieces cannot be realized only by the horizontal and vertical movement of the worktable. Disadvantages: Due to the limited size of the workbench, the size and weight of the processed workpiece are also limited by the size of the workbench; and the workbench is not suitable for making it very large, because it is limited by the installation space, and it is difficult to realize the workbench if it is too large. Moves, or requires a lot of driving force, wasting energy
