This invention relates to the woodworking industry.

The purpose of the invention is to increase the safety of work and expand the functionality of the machine.

FIG. 1 shows the kinematic scheme of the proposed machine; in fig. 2 - the proposed machine with an open side wall; in fig. 3 - the same plan view; in fig. 4 - grinding wheel with a handhold; in fig. 5 - chuck with bail-out jHbiM table for drilling and milling operations; in fig. 6 shows section A-A in FIG. 3; in fig. 7 - diagram of the positions of the knife shaft when turning the sleeve.

The machine includes a frame 1, table 2, a molded disc 3, a saw blade guard with a wedge knife 4, a spindle shaft 5 placed on bearings 6 eccentrically rotary sleeve 7, axle sleeve 8 for turning and fixing the sleeve 7 and the knife drum 9 rigidly fixed on the spindle shaft 5. The electric motor 10 is mounted on a rotary plate and has two output ends. At one end of the shaft, there is a grinding wheel 11 for sharpening a tool, on the other - a pulley 12 connected by a V-belt 13 to a pulley 14 mounted on a spindle shaft 5. The rotatable plate of the electric motor 10 and the turn sleeve 7 are pivotally connected by adjustable bars 15 with a screw 16 for tensioning belt. Fencing 17 nozhevo-. the drum is raised by the cam 18 of the sleeve 7. only when jointing. The spring 19 serves to return the fence 17 to its original position after passing the workpiece, and also fits the fence flush with the top. When planing the blanks, the knife drum 9 is turned by the sleeve 7 and fixed in one of the upper positions bc or c-d (Fig.7). When this cam 18 sleeve 7 pushes the fence 17 up. Accordingly, the plate 30 of the table 2 and the knife drum are set to the required position depending on the thickness of the chips to be removed. With the passage of the workpiece, the fence deflects to the right, and after the passage of the workpiece returns to its original position, closing the slot above the knife drum.

When performing a sawing operation, it is necessary to install it in tulka 7

20 of the positions e-f (Fig.7) and fix it. In this case, the fence 17, under the action of the spring 19, will fall behind the face with the plane of the table and close the slot above the knife drum. The cutting height is also adjusted by turning the sleeve 7 to any of the e-f positions. In the g-h position, the saw is moved to the lower non-working position.

To sharpen the tool (Fig. 4), it is necessary to turn the sleeve 7 to the k position or close to it. This will open the flap and the grinding wheel 11 will go out of it outside the machine by the required amount for the production of grinding work. The hatch cover itself is used as a binder 28 for ease of sharpening.

Milling and drilling operations can be performed using the chuck 26 for fastening the tool and the side table 27 (Fig. 5). At the same time, the spindle shaft with chuck can be35
