Description

A plane surface cutting machine of the cutter}

The present invention relates to a planarizer for evenly cutting the uneven surface of a road surface, smoothly processing the floor surface of a building, or performing a surface processing operation for removing rust or impurities from an iron plate, etc. The operator lowers a predetermined distance by using a handle on a workbench equipped with a cutter drum, which is equipped with a plurality of cemented carbide chips made of cemented carbide or special steel for smoothing the surface of the road, building surface, and steel plate. The drum is brought into contact with the surface layer of the work piece, so that the cutter drum can be moved up and down finely to process the surface more precisely, so that the surface layer of the work piece and the carbide chip of the cutter drum are properly contacted. It can keep the surface layer of the workpiece smoothly and smoothly by one working process. It relates to a planing machine capable of fine stroke adjustment of the cutter drum to make.

In general, the planarizer performs the removal and cleaning of the new site, the removal of the cement projecting part or the removal of the hydroxy coating, and the finishing process by forcibly smoothing the uneven part of the road surface after road construction. After the building construction, the floor surface is smoothed for the finishing process of the interior floor, and the floor smoothing work is performed to facilitate the floor tile work, paint, paint work, or the like. The planarizer 10 is used to grind the surface layer, and as shown in FIG. $$, the planer 10 rotates the cutter drum 1 and the cutter drum 1 to which a plurality of cemented carbide chips are attached. The driving means 4 and the driving means 4 made of a driving body 2 and a driving pulley 3 for smoothing, and the driving means 4 are mounted. When the work table 5 to be mounted therein, the fixed support 6 extended and extended upward from one side of the work table 5, and the cutter drum 1 are transported downward during work and the work is finished, Cutter drum lifting means (7) for conveying upward is embedded in the fixed support (6), the handle (8) for operating the cutter drum lifting means (7) on the work table (5) It is common to have a structure in which a plurality of casters 11 are mounted below the handle 8 and the work table 5 to facilitate the transfer of the planarizer 10 to the top of the work table 5.

Briefly explaining the operation state of the general planarizer 10 having the structure as described above, the workpiece (for example, bumpy road surface, building bottom surface, iron plate, cement projecting) that the worker intends to perform the surface processing work Part, epoxy coating surface, etc. (hereinafter referred to as the workpiece) 20, the handle 8 and the cutter drum are lowered when the handle 8 mounted on the top of the fixed support 6 is lowered. Rods (not shown) connected so as to be interlocked between the worktables 5 to be built up are also simultaneously lowered so that one side of the worktables 5 connected to the rod ends is transported downward and the workpiece 20 The cemented carbide chip of the cutter drum 1 is in contact with the surface of the workpiece 20 so as to maintain the contact with the surface of the workpiece 20.

When the cutter drum 1 abuts on the surface of the workpiece 20 as described above, the operator drives the drive body 2 of the drive means 4 to drive the drive pulley interlocked with the drive body 2. (3) the cutter drum 1 is rotated, and at the same time the cemented carbide chip of the cutter drum 1 grinds the surface layer of the workpiece 20 to smooth the surface layer of the workpiece 20, It will be able to flatten the surface.

However, there are many cases where the surface of the workpiece is not uniform, and the unevenness of the workpiece is also different, and even if the same workpiece is different, the difference is inconsistent, and thus there is a limitation in obtaining a smooth surface of the workpiece. In addition, after the surface smoothing process by the planarizer by the first surface work, the surface of the workpiece should be smoothly processed by using a separate equipment such as a grinder to smooth the surface of the workpiece. This ensuing problem has been pointed out, and economic problems such as delay of work and an increase in work cost have been pointed out.

On the other hand, the conventional planer allows the cutter drum to be lowered as much as the handle drum is lowered, in which the raising and lowering stroke distance of the cutter drum is set in advance, so that the stroke length of the cutter drum cannot be selected. Therefore, it has been shown that the limitation can not be easily applied.

Therefore, the present invention has been devised to solve the above problems, so that the operator can selectively adjust the up and down stroke stroke of the cutter drum according to the surface degree of the workpiece regardless of whether the surface of the workpiece is smooth or not. By actively adjusting the position of the cutter drum according to the roughness of the workpiece surface, it is possible to process the workpiece surface completely by one process without using any additional equipment. There is a fundamental purpose of the present invention.
