Description

The invention relates to woodworking equipment and can be used in universal and household, machine tools, ...-

The purpose of the invention was to reduce the changeover time.

. In FIG. 1 - general view of the machine; FIG. 2 is the same side view; FIG. 3 is a section AA in FIG. 2; Fig. 4.-clutch. . .

The machine contains a bed 1, an upper folding table 2 with bkn.m.Z for a knife shaft 4, a window 5 for the length of the seam and shaped disc milling cutters and a window b for a saw blade 7. Upper table 2: consists of a front movable part 8 lifted by means of eccentric rollers 9 and the rear fixed part 10. On the surface of the table 2, a guide ruler 11, a lifting guard 12 of the saw blade 7. are fixed. with a swing ranging from + 5 ° to -44 ° in half shafts 13, the hollow body 14 of the planing unit 15. On the upper base 16 of the hollow, body 14, a knife shaft 4 is fixed and an additional window 17 for the knife shaft is provided. In the cavity 18 there is a lower (thicknessing) table 19 installed in the Controllers 20 with the possibility of raising and lowering by a screw mechanism 21, mounted on the lower base 22 of the housing 14, and provided with clamps 23. At the end of the housing 14 is rigidly, by means of the plate 24, the saw block 25 is fixed, including the saw shaft 26, its pulley 27 and the saw blade 7. The saw shaft 26 has a seat for turning and drilling chucks or the installation of end mills, and the frame 1 has holes 28 for installing a rod with a support clamp, armrest and rear headstock or drill a small table (to hell, not shown). A drive 31 in the form of a single-phase asynchronous motor with a drive gear coupling 32, made in the form of a gear ring 33, is fixed to the lower base of the housing 14 by means of a plate 30. the shaft 34 of the motor 31 with the possibility of longitudinal movement along the shaft 34 by means of a sleeve 35 and levers 36 associated with a threaded flywheel 37. Toothed, the crown 33 is able to engage with the radial splines 38 of the pulleys 39, 40 connected by means of belts 41,42 respectively a pulley 27 of the saw shaft 26 and a pulley 43 of the knife shaft 4, which are: mounted on the shaft 34 by means of bearings. :

To rotate the hollow body, a swing (swivel) mechanism is pivotally attached to the drive fastening plate 30

made in the form of a screw pair 44 with a handle 45; and to fix the position, the housing 14 has a latch 46 with a handwheel 47 mounted on it from the side opposite to the saw block 35 and passed through the curved groove 48 of the sector guide 49 fixed to the frame 1 .. - .- . :. . The housing 1.4 of the combustion unit, which is installed with the possibility of swinging from + 5 ° to -44 ° when counting from the horizontal placement line of the upper base 160, has three fixed positions:

- + 5 ° - for simple jointing, jointing 5 at an angle and along the edge, milling

shaped and seam cutters; wherein

angle + 5 ° is necessary for the departure of the cutting

the edges of the knives of the shaft 4 to the level of the table 2; .

- middle position (0 °) for surface planing, turning, drilling, milling; .

- the position up to -44 ° is used for - longitudinally at any angle and transverse sawing, or pieces further

5 departure of a saw disk. It is limited by a saw shaft,; . ;.; :. ...:. /. The machine works as follows,

For simple jointing, remove the valve (to hell, not shown) from window 3,

0 set the rotation of the handle 45 of the casing 14 to the upper position (+ 5 °), fix it by twisting the handwheel 47, rotating the handwheel 37 counterclockwise, switch clutch 32 to the operation mode 5, while crown 33 engages with slots of pulley 40, which when switching on, the front axle 31 transmits the rotation by means of a V-belt transmission to the knife shaft 4, then set table 2 to the required / height, turning the eccentric rollers 9, while the movable part 8 of table 2 will move, set to the desired position e.g. The guide line 11 is turned on at 31 and the billet is fed to the knife shaft 4 along the table 2 from the side of its front movable part 8.

After leveling one of the surfaces of the workpiece, you can turn it over and

50 to process the second surface.

For calibration, a workpiece with one side machined, for example, planing, is machined on a thicknessing table 19, for this purpose the housing 14 of the planing block is released by the handwheel 47, the housing 14 is turned into the middle (horizontal) position by turning the handle 45, and this position is fixed by the handwheel 47 by turning the central screw of the lifting mechanism 21, set the necessary

the height of the table 19, include the drive 31 on the knife shaft 4 and feed the workpiece into the cavity 18 on the table 19 from the back of the side 10 of the table 2, i.e. with the opposite feed of a relatively simple planer. When the workpiece is fed into the gap between the table 19 and the upper base 16, the workpiece is pressed against the table by the clamps 23, passes through the rotating knife shaft 4 and leaves the saw block 25.

For longitudinal sawing at any angle, transverse sawing and sawing to a certain depth, the guide 11 on table 2 is installed in the corresponding position, turning the handle 45 of the swing mechanism, lower the planing unit housing 14 to the lower position, while the sawing unit 25 rises, the housing position 14 is fixed by the handwheel 47 in the required position depending on the desired height of the saw blade 7, switch the clutch 32 by rotating the handwheel 37, engage the pulley 39 with the crown 33, turn on the drive

31 and sawing on table 2,

For turning, a rod is installed in the holes 28, it is fixed by means of brackets, a support clamp with a cup and a handrail is mounted on the rod, the tailstock is removed from the saw shaft 26, the saw blade 7 is installed, the self-centering chuck is installed by turning the swing mechanism of the planing unit housing by the handle 45 install the necessary

the center distance between the saw shaft 26 and the bar, fix the position with the handwheel 47, set the workpiece and carry out turning.

Similarly, the installation of cutters

on knife shaft 4 or saw shaft 26 and milling of parts.
