Description

COMBINED WOODWORKING MACHINE The inventive utility model relates to the woodworking industry, in particular to combined woodworking machines, and can be used in domestic conditions, in small enterprises and repair shops, as well as in school workshops and educational institutions.

The invention is known The cutting mechanism of a universal woodworking machine according to copyright certificate No. 1569241, class. B27C9 / 00 publ. 06/07/90. The technical cyui of this invention lies in the fact that the cutting mechanism of a woodworking machine includes a bed on which a spindle drive shaft is mounted, bearing a knife shaft, clamping flanges for a circular saw on one side and a hole for attaching a drill chuck on the other hand, where it is simultaneously fixed in a support rolling and with the use of an eccentric cylindrical groove mortising mill. The operation of the cutting mechanism is as follows. The rotation from the electric motor through the V-belt drive is transmitted to the spindle, on which all cutting units are mounted. After the sawing operation by the saw, the saw must be removed to perform the cylindrical milling operation. Transfer to all cutting units is carried out without intermediate links. The sawing operation can be performed without disassembling anything, and during the drilling operation it is necessary to remove the mortising mill and vice versa.

When turning the planer saw 8 to the side saw device 4 is provided by sawing the material to a predetermined width. All devices operate from the IT control panel,

The combined woodworking machine operates as follows.

 for thicknessing operations, the necessary clearance is pre-set between the knife shaft 12 and the thicknessing table 14 by lifting it using the lifting mechanism 25, driven by the rotation of the handwheel 30. Having set the required clearance, the electric motor 24 is turned on, which is driven by the rotation of the knife shaft 12 and simultaneously the feeding mechanism blanks 13. Then advance the blanks 34 material on the thicknessing table 14, which captures the feed corrugated shaft 32, moves it to the receiving smooth shaft 33, and knife l 12 carries out thicknessing.

The day of the planing (jointing) workpiece, the workpiece is laid on the falling table 46 and raising or lowering it

achieve chip removal from the processed material necessary thick. The receiving rear table 47 is flush with the upper point of the trojectories of the knives 15, after which the electric motor 24 is turned on and the knife shaft 12 is rotated through the V-belt drive 22 and the knives 15 are planed. Moreover, if the planer-joint stop 8 is installed in the direction of the planing device 3, it is possible to process the workpieces in a plane to the edge, as well as planing the edges at an angle from O to 45 °.

For sawing, the saw 50 is mounted on the spindle 49 between the flanges 54 and 55, and then, using the lever 58, the desired cut height is fixed and fixed, after which the electric motor 58 is turned on, which, using the V-belt 56, rotates the saw 50 through the pulley 56. the miter-saw stop B allows you to adjust the width of the saw cut, as well as to carry out transverse sawing, the length required and to cut the workpieces at an angle.

For milling operations, the spindle bb is installed through spacer sleeves 69 of the milling cutter 68 and, using the handwheel 73 and bevel gear 72, its height is adjusted above the milling and saw table 48. The workpiece to be machined is mounted on the tenoning table 79 using the contact angle 80 and using carriage 78, the workpiece approaches the milling cutter 68, which receives rotation from the electric motor 76 through a V-belt drive 75. On the spindle 66, in addition to the milling cutter 68 of various thicknesses and profiles, a grinding wheel for grinding can be installed both planer knives 15, and various other tools (drills, lathe tools for wood, etc.).

-8- For drilling operations, the workpiece to be machined is installed on the table 85, and by moving the table 81 set it at the required distance relative to the drill chuck 82 and moving the table 85 in the horizontal plane, the drilling process is carried out.

For the production of turning operations, pre-vertical movement of the turning device 7 using the template 105 provides the same distance from the surface of the drilling table 85 to the cylindrical surfaces of the front 103 and rear 97 centers. Mark holes with a diameter of 3 mm at the ends of the workpiece strictly at the intersection of the diagonals. An adapter 102 with a front center 103 is mounted on the conical end 83 of the knife shaft 12. Then, place the workpiece with one end in the front center 103, and bring the rear center 97 to the other end of the workpiece, fix the housing 96 with the nut 101 and screw 100, and then preload the workpiece using screw 98 and handle 99. Bring bracket 104 to maintain the cutter, ensuring minimum clearance to the workpiece. After that, the electric motor 24 is turned on, which transmits rotational motion to the blade shaft 12 and to the front center 103. The workpiece is rotationally driven, a cutter is fed to it and thereby the workpiece is turned.

Depending on the type of work, either a drill chuck 82 or a faceplate (not shown) is installed on the tapered end 83 of the knife shaft 12, for surface grinding and polishing work, or a sharpener for knives, milling cutters and drills. Slacking the machine with the proposed arrangement on the bed of devices of various functions allowed to create a combined woodworking machine, on which there is a possibility to carry out all types of woodworking operations. At the same time, this tool grinds all the tools used on it. Moreover, all operations on woodworking and tool sharpening are carried out without any readjustment of the machine.
