The woodworking combined machine consists of a frame, made in the form of two arched supports 1, fastened at the top and bottom with ties 2. The fixed saw table 3 with a saw 4 and two parts 5 and 6 of the planing table are strengthened on the frame. One part of the planing table 5 is made adjustable to control the depth of planing. The second part of the table 6 can occupy two extreme pol 2 029973

: closed when the planing spindle 7 is closed, and open when the spindle is open, and the table plane coincides with the cutting edge of the planing spindle 7. The planing spindle 7 can be equipped with a taper 8 for fitting the tool cartridge (not shown) and attaching the end tool (not shown). Parts of the planing table 5 and 6 are repositioned using the handles 9. These handles are attached to the short sides of the 10th parallelogram mechanism. When lifting the handles, 9 parts of the planing table 5 and 6 rise to the closing and close the planing spindle 7. At the same time, both parts of the table are adjusted so that they form one plane with the saw table 3. To put the planing table into working condition, the handle 9 is lowered, while unregulated part of the table 6 is lowered onto the stops so that the cutting edges of the planing spindle 7 are in the same plane with this part of the table 6. The adjustable part of the table 5 has the ability to fall below the cutting edge of the planing spindle 7. Both parts of the table 5 6 are fixed in their positions by means of handwheels 11. At this planing depth (under-adjustable table portion 5) is displayed on the index scale 12, and the table 5 can be secured by means of handwheels 11 for any desired height.

The drive motor 13 is equipped with a pulley 14 on which a belt 15 is attached. This belt simultaneously covers the pulley 16 of the planer spindle 7 and the pulley 17 of the saw spindle. The planing spindle 7 is fixed in the machine bed and fixed, and the saw spindle is fixed on the rod 18 mounted on the bed so that it can be rotated around the axis A. The axis B of the planer spindle 7, the axis B of the drive motor 13 and the axis A of the rotation of the rod 18 form an approximately equilateral triangle with the base BV. The circuit in FIG. 6 shows the change in the position of the connecting rod 18, while the estimated length of the belt 15 with such geometrical parameters of the drive remains constant. Thus, no additional action on the tension of the belt 15 to compensate for the change in its estimated length when changing the position of the connecting rod 18 is not necessary.

The mechanism for changing the position of the connecting rod 18 is used to change the depth of sawing (the height of protrusion of the saw 4 above the surface of the saw table 3). This mechanism can be performed in the first embodiment in the form of a gear 19, mounted on the axis of the saw spindle. Gear 19 is fixed on the shaft 20 with the pin 21 for its rotation using the flywheel 22. Coaxially the shaft 20 has a lock nut 23, which is clamped using the handle 24, fixing the position of the saw spindle, therefore, the saw. Gear 19 engages with a sector 25, mounted on the frame of the machine. According to the second embodiment of the mechanism for changing the position, the connecting rod 18 is equipped with a lever with a handle 26 and a clamping bar with a lever 27.

The mechanism for blocking movement of the saw 4 with the handle 9 lowered is the body of the connecting rod 18, on which the saw spindle is fixed (not shown in Fig. 9 and 10) mounted rotatably around the axis A. In the connecting rod 18 there is an opening for the stopper 28, which is hinged element 29 is connected with the pusher of the handle 9 or the table 6. With the table 6 lowered, as well as the handle 9, the stopper 28 does not allow the connecting rod 18 to turn and, accordingly, raise the saw 4 above the surface of the saw table 3 (Fig. 10). If in the initial state of FIG. 9 first raise the saw 4, turning the connecting rod 18, the stopper 28 will not be able to move freely to the left into the hole, and, accordingly, will not allow the planing table 6 to be lowered, opening access to the planing spindle 7.

For the convenience of managing a multifunctional machine when performing various actions: sawing, planing, working with end tools - drilling, slotting grooves, shaped processing of the ends from different positions of the working start button of the electric motor 30 is fixed on the swivel bracket 31. This bracket is fixed on the base 1 using the hinge node 32. Thus, when sawing, the bracket 31 is turned as far as possible to the left to provide access to the start / stop button of the electric motor from the side of the saw table. When working with an end tool on the cone 8 of the planing spindle 7, the bracket 31 is turned to the maximum to the right. When setting the machine in the planing position, the bracket 31 occupies an intermediate position. To meet the safety requirements, the saw is equipped with a lifting shroud 33. To work with the end tool, the machine can be equipped with an additional table with a ruler (not shown), which are made by any known method, for example, fastening to the left rack of the machine.

The machine is designed, tested and manufactured at the Belmash Plant LLC in Mogilev, Belarus.

The positive effect is achieved by simplicity of design, wide versatility, high level of security and ease of operation and maintenance.
