The invention relates to woodworking, in particular, equipment for processing wood blanks in a domestic environment.

The purpose of the invention is to expand the functionality of the machine due to cutting style processing and improving the quality of processing workpieces.

Figure 1 shows a universal woodworking machine, a general view5 of FIG. 2, section A-A of FIG. 1, inserts are removed; on fig.Z the same, inserts are established; in fig. 4 - a general view of the machine when sawing; in FIG. 5, FIG. D in FIG. 4, the guide tab coincides with the plane of the saw blade and is parallel to the offset relative to it; 6 is the same, the guide tab is offset at an angle relative to the saw blade.

The machine includes a housing 1, a front table 2, a rear table 3, inserts 4, 5 (FIG. 3) that can be mounted with fasteners (not shown) in the longitudinal grooves of the front and rear tables, respectively, and the mount 6 of the removable pinch roller 7. The front and rear tables are interconnected by means of a frame 8 (FIGS. 2, 3).

The bottom surfaces B and C (Fig. 2) of the longitudinal slots of the front and rear tables form shaped tables. On the blade shaft 9, depending on the type of workpiece processing, either a figure knife 10 is installed (Figs 1, 2) or a straight knife 11 (Fig, 3).

When sawing (Fig. 4), the presser roller is absent on the machine, and an interchangeable table 12 is installed on the surface of the front and rear tables. The protective casing 13 is mounted on the interchangeable table and integral with the guide tab 14. It protects the worker from contact with the saw blade 15. The guide tab 14 is attached to the removable table by means of screws 16 with eccentric washers 17 (Fig. 4-6). The guide foot serves as a centering knife. Clamp 18 serves to attach the machine to a workbench or other desktop.

The drawings do not show the structural elements that serve to raise and lower the front and rear tables and provide a certain

the thickness of the material removal during planing and shaping, as well as the drive and attachments for milling and turning with working bodies.

The machine works as follows.

When performing a planing operation, a removable IQ pressure roller 7 is installed on the machine along with its mounting unit 6, and the inserts 4 and 5 are installed in the longitudinal slots of the front and rear tables (Fig 3) and secured by means of clamps (screw 15). Straight knives are mounted on the blade shaft 9, after which the drive is turned on and the workpiece is fed for planing. The thickness of the removed layer should not exceed 4-6 mm. In case of need to remove a layer of greater thickness, they resort to sawing.

When changing the machine to the shaped processing of blanks, the inserts 4 and 5 (Fig. 3) are removed from the machine, freeing the bottom surfaces of the B and C grooves (Fig 2), which form the tables for the shaped machining. Include drive and feed the workpiece into the machine. This ensures the removal of a layer of material with a thickness of up to 14 mm, which is sufficient for the manufacture of baguette-type products.

When retooling the machine for carrying out the sawing operation (transverse and longitudinal), the pressure roller 7 is removed from the machine along with its mounting unit 6. Then, in the slots of the front and rear tables, the inserts 4 and 5 are fixed, thereby restoring the surface of the tables, which was during the planing operation (Fig. 3). After that, the replacement table 12 (Fig. 4) is mounted and fixed and the pil - 45th disk 15, on which the guideway 14 of the protective casing 13 is adjusted by means of screws 16 with eccentric washers 17. The sawing disk cuts the workpiece and on it performs an exact alignment of the guide foot 14, after which the foot is fixed with screws 16 ( Fig.5,6).

The machine is equipped with lathe and milling attachments that are attached to the machine body from the side of the spindle of the cutter shaft 9. The cutters are installed in the spindle of the cutter shaft with the help of collets. Turning treatment for 30
