DETAILS DESCRIPTION OF THE INVENTION

[0026] One embodiment of the machine for processing of outer surfaces of volumetic objects in assembled state according to the utility model is described below as the constructive elements used and their mutual orientation do not restrict the use of other equivalent elements or materials with the same properties and functionality.

[0027] The machine for processing of volumetric objects is suitable for processing of metal cabinets for the electric industry wherein in assembled state on the body of the metal cabinet is possible to be cut slots, holes or other cuts, determined in advance by location, form and size.

[0028] The machine consists of frame 1, places on four leveling legs 2 whereupon on frame 1 is fixed working table 3, on the top surface of which is placed the processed volumetric object 4—cabinet or two-dimensional object—sheet material. At the outer parts of the frame 1 on a horizontally oriented beams 5 are fixed linear guide ways, on which are placed two vertically oriented carriages 6, parallel to each other. In their upper part the carriages 6 are connected with cross beam 7, horizontally oriented towards X axis, which beam is positioned perpendicularly toward the Y axis.

[0029] On the cross beam 7 are installed at least two linear guide ways, to which is horizontally attached carriage 8, having the option to move along X axis. Ram 9 is installed to the carriage-8, with an option to move in vertical direction along Z axis, as at the same time it carries guide ways along the mentioned Z axis, which guide ways move along X axis through the carriage 8.

[0030] At the bottom of the ram 9 are installed two rotary axes, respectively-vertically oriented. “C” axis 10 and “B” axis 11 perpendicular to the “C” axis 10, equipped with driving mechanism. Thus the driving mechanism of “B” axis 11 is installed on the processing unit of “C” axis 10. At the processing unit of “C” axis 10 is installed also driving mechanism of a secondary translational “LH” axis 12, equipped with movable carriage (saddle), on which is fixed cutting tool, for example laser head 13, as the “B” 11 axis and the carriage “LH” 12 have perpendicular axes.

Machine Operation According to the Invention

[0031] The machine for processing of metal cabinets, in assembled state according to the utility model is used in the following way: the processed object, for example assembled body of a metal cabinet, designated for installation of electro-technical elements has to be placed on a worktable-3 on a certain position from the machine's coordinate system. The processing is realized consequently surface after surface, according to a program, set in advance in the CNC (Computer Numerical Control) system.

[0032] By driving the described three translational axes X, Y, Z is provided the necessary accurate positioning in the working volume of the machine and the rotation around the vertical and horizontal axis provides the normal (perpendicular to the processed surface) positioning of the cutting laser head 13 to the respective processed surface. An additional translational analog axis coaxial to the axis of the cutting head 13 provides a constant distance between the working tool and the processed surface by compensating the deviation from the nominal location (for example the non-flatness of the flat surfaces), which is necessary for normal functioning of a thermal cutting.

[0033] The drive of the rotary axes “B” and “C” and translational axes “X” “Y” “Z” is performed by mechanisms without backlash, which allows high accuracy and smoothness of movement of the working head.

[0034] An additional option is threading of drilled holes. For this purpose is mounted tapping device positioned coaxial with the cutting head. It is not shown on the figures.
