BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movable planar processing machine for repairing a plane of a large structure.
The present invention is characterized in that when it is necessary to precisely repair a plane of a large structure installed on the site, the entire large structure or the large structure is disassembled and disassembled and is not moved to a position where the plane processing machine is installed, The present invention relates to a movable planar processing machine capable of performing maintenance directly at a site where the robot is installed.
As an example of this, a case of using a triple sonic wind tunnel will be described.
The inner side of the sidewall, which constitutes the triple sonic wind tunnel, consists of a finely machined plane to homogenize the flow of fluid into the nozzle. The sidewall of the wind tunnel is formed on a scale having a volume of approximately 11.6 m x 4.5 m x 1 m and corresponds to a large structure having a self weight of 30 tons. Therefore, when the machined surface of the sidewall of the wind tunnel is broken or damaged, it is necessary to disassemble the sidewall of the wind tunnel having the above-mentioned scale and weight and move it to the position of the manufacturer of the plane machine capable of machining the plane of the large structure There was a difficulty.
In addition, it is very difficult for a company having a planing machine capable of processing the plane of a large structure as described above, and it is very difficult to tune the schedule for working with the planing machine. These problems make it difficult to repair wind tunnel quickly.

According to another embodiment of the present invention, there is provided a movable planar machining apparatus characterized in that the grinder is capable of selectively replacing and installing head parts of various sizes.
According to the present invention, when a flat surface of a large structure having a flat surface is broken, the large structure can be disassembled and the large structure can be flat- It enables quick and precise plane machining.
In addition, by adjusting the fine height, it is possible to finely adjust the depth of plane processing or the depth of cut.
In addition, by providing the reference point and the dial scale, it is possible to recognize the machining depth or the depth of cut of the plane to be machined through the movable planar machining apparatus of the present invention before starting the cutting operation.
Further, by providing the handle, the movable planar processing machine of the present invention can be easily moved, and the working radius can be widened.
Further, by providing the holder, it is easy to attach and detach the grinder constituting the movable planar processing machine of the present invention.
In addition, the portion of the movable planar machining apparatus according to the present invention, which is in contact with the plane to be machined, is made of a material having a hardness lower than that of the machining plane, thereby minimizing damage to the machining plane.
Further, since the head portion of the grinder constituting the movable planar machining apparatus of the present invention can be replaced with the head portion having various grain sizes, it is possible to allow the operator to process the flat surface with the desired roughness.
