    FIELD: machine tool industry. A device for sharpening a cutting head is known, which contains a grinding head and is mounted on a movable base by means of turning and rotating mechanisms, a tool of a mental head 1. However, the known device is cumbersome and does not provide sufficient accuracy in machining cutting tools knives. howling head. The purpose of the invention is to reduce the size and increase accuracy. To achieve this goal, the rotation mechanism is installed at a minimum acute angle to the rotation mechanism, while the rotation mechanism is designed as a lifting table with hydrostatic bearings, carrying a rotary support, and the rotation mechanism is designed as a folding base, which is mounted rotation around the axis of the latter, the rotation mechanism is kinematically connected with the rotational support of the rotation mechanism through a worm gear and provided with mounting gears. device made as a set based on the jump ring with a lever on one end of which is located a spring-loaded latch, and the other is set to be in contact with the piston cylinder, wherein the tool holder is provided with a removable divider plate with grooves, intended for contact with the retainer. Figure 1 shows the device, a general view; figure 2 - the device in the rotated position, a General view; on fig.Z - holder incisor head with an adjusting ring; Fig. 4 shows a kinematic connection of the rotation mechanism with the rotation mechanism; Fig.5 diagram of the rotation of the cutting head; on fig.b - installation of a device for sharpening a cutting head on a grinding machine; Fig. 7 is a simplified view of another embodiment of the device for sharpening the cutting head. The device consists of a clamping device 1 with five main elements: a movable table 2, a lifting table 3, a turning part 4, a hinged part 5 and a holder 6 of the cutting head. A chisel head 7 with a chisel 8 is mounted on the clamping device. The remaining chisels in the chisel head 7 are not shown in order to simplify the drawing. In addition, the grinding wheel 9 is visible, located on the grinding machine 10 (Fig. 6) with the possibility of movement in the vertical direction.
    The cutting head 7 is connected through a cone 11 without backlash with the holder 6 of the cutting head fixed to the tool part 5 so that it can be rotated around the axis 12 of the cutting head. In this case, the holder 6 of the cutting head is supported through the rolling bearing 13 on the folding part 5. A cylinder 14 placed on the folding part 5 serves for. transfer of pressure oil from the hinged part 5 to the holder 6 of the cutting head.
    The folding part 5 is mounted on a rotatable part 4, deflected around the axis of the opening 15, which intersects the axis 12 of the cutting head at an acute angle cf. The cylinder 16 placed on it also serves to transfer pressure oil. In axial direction, the flap part 5 rests through the bearing ring 17 on the rotary part 4. A tram spring 18, inserted between the bearing ring 17 and the worm wheel 19 mounted on the flap part 5 /, pushes the flap part 5 to the bearing ring 17 and distributed throughout the perimeter of its circumference is connected to the oil-pumping unit. The bearing ring 17 forms with the pockets 20 a hydrostatic bearing 21 for the flap part 5.
    Another hydrostatic bearing 22. consists of pockets 23 (shown by hatching), which are located in the ring and are connected to the lifting table 3. These pockets are also connected to the oil-sealing assembly. The swivel part 4 is rotatable around the axis of rotation 24, which is inclined relative to the deflection axis 15 at an acute angle on the lifting table 3, and the cylinder 25 fixed on it serves to transfer the melodious oil to the rotary part 4. The spring 26 tightens the rotary part 4 to. lifting table
    The worm to 27, mounted in the rotary part 4, engages with the worm wheel 19. By turning the worm 27, the hinged part 5 can be removed on the rotary part 4. Due to the friction of this worm gear, the hinge part 5 is not able to turn on the swivel part 4 when the worm is stopped, ke 27.
    Lifting table 3 is placed on the movable table 2 with the possibility of vertical movement. A shaft 28 fastened on it serves as guides, which is inserted without a backlash into the boring hole 29 in the lifting table 3. Similar rails 28, 29 are placed on both sides of the rotary part 4.
    The device is equipped with a mounting device 30.
    On both sides of the rotary part 4 are the rack 31 of the bearing. In the boring hole 32, a shaft 33 is inserted in them, which is connected to a folding lever 34. At the end of the folding lever 34, a wheel 35 is mounted, which can roll along the surface 36 of the movable table 2. Two opposite wheels 35 or folding arms 34 are connected by means of a bracket 37 between by myself. This bracket 37 by means of a piston rod 38 is connected, for example, with a hydraulic cylinder 39 connected to an oil pressure unit. A spring 41 is inserted in the cylinder 40, which is pre-tensioned. At the same time, it rests on the cylinder 40 on one side and on the plate 42 on the other side, which is fixed at one end of the rod 43 rigidly fixed with the other end by means of a finger 44 on the folding lever 34. This device serves for leveling the weight so that the lifting movement requires less effort and shafts 28 perceive minor radial forces.
    The retracted part 5 deviates from its position by 180 ° around the axis 15 of the deviation. The axis 12 of the cutting head and thereby the cutting head 7 is inclined in this position by a double angle S between the axis 12 of the cutting head and the axis 15 of deflection to the axis of rotation 24.
    A cylinder 45 is provided on the retracted part 5, in which the piston 46 moves reciprocally. This piston 46 consists of two parts (FIG. 4), namely from the outer piston 47 and the internal piston 48. These parts are interconnected by a threaded joint 49. A tetrahedral rod 50 enters at one end into the inner piston 48 and at the other end is fixed in the adjusting ring 51. By rotating the adjusting ring 51, the tetrahedral rod 50 and also the inner piston 48 can be rotated. In addition, caivttJM inner piston 48 and outer piston 47 screwed or unscrewed, resulting in a change in the total length of the piston 46. In the outer piston 47, a gear rail 52 is embedded on one side, which is in engagement with the cylindrical toothed wheel 53. Thus, the outer piston 47 is prevented from being turned in the cylinder 45 Since the length of the cylinder 45 is constant, and the length of the piston 46 is variable, it is possible to adjust the stroke of the piston 46 and, accordingly, the angle of rotation of the cylindrical gear 53 by the amount of stroke on the mounting ring 51. Around the holder b incisive goal A ring 54 is attached, i.e. a groove 55, into which oil can be pumped through the oil lines. The ring 54 is supported on the gear 53 which surrounds it from below, between the cylindrical gear 53 and the ring 54 there is sufficient play so that the cylindrical gear 53 can rotate freely. Once the oil is pressed into the groove 55 under pressure, the wall 56 of the ring 54 is pressed to the side of the cylindrical gear 53, whereby the play is reduced. The cylindrical gear 53 in this case mates with the holder b of the tool head. The separating disk 57 fixed on the holder of the incisal head is removable and has a series of notches 58 on its circumference. Concentric with the axis 12 of the incisal head there is a mounting ring 59, on which is placed the lever 61, which is turned around the bolt 60, which has an adjusting The cam 62, the shape of the notches 58 is the same as the shape of the adjusting cam 62, so that they can engage with each other without a gap. In the quiescent state, the spring element 63 presses the adjusting cam 62 into one of the notches 58. The cylinder 65 is placed in the cylinder 64, which is connected at the other end to the lever 61 and can while it has oil pressure through the oil pipe 66 turn the lever 61 around the bolt 60 against action of the spring element 63. Thus, the adjusting cam 62 is removed from the corresponding notch 58 and the holder 6 of the cutting head and the adjusting ring 59 can now turn relative to each other. The adjusting ring 59, the separator disk 57 and the lever 61 are closed by a cover 67 and are protected from contamination. The setting ring 59 has a slightly cone-toothed engagement 68 and, through the support surfaces 69, rests on the hinged piece 5. The engagement 68 includes a tapered gear 70 fixed on the shaft 71. The shaft 71 is inserted, for example, by means of a rolling bearing 72 into the hinged piece 5 and bears on the outer end of the handwheel 73. When the handwheel 73 rotates, the adjusting ring 59 turns on the hinged part 5 around the axis 12 of the cutting head. The squeeze device is 1 times on the grinding machine 10 with a grinding wheel 9. When rotating the wheel 74, you can move the moving thickness 2 and thus the entire clamping device 1 parallel to the plane of the grinding wheel 9 and the handwheel 75 perpendicular to the last. Figure 7 shows a second embodiment of the jig. In this case, the projection of the deflection axis 15 is parallel to the axis 12 of the cutting head. The deflection axis 13 is also inclined to the plane of the drawing, or the deflection axis 15 and the axis 12 of the tool head are diagonally opposite one another. In the hatched plane 76, the incisal head 7 can be seen with the incisors 8 on the side of the tips or the surfaces of the head 77. The shortest distance is about. between the axis 12 of the cutting head and the real axis 15 of the deflection is near or in the region of the plane 76, the device operates as follows. To sharpen the front or rear surface of the cutter 8, the cutting head is placed on the holder 6 of the cutting head. A screw coaxial with the axis 12 of the cutting head serves to engage the cutting head 7, and a radially running wedge serves for positioning, so that the cutting head 7 cannot be arbitrarily turned and placed on the holder b of the cutting head. The pitch disc 57 has a number of cuts 58, which corresponds to the number of incisors on the cutting head. In this case, for a different type of incisors, the dividing disc 57 is changed to the nozzle of the incisal head 7. Accordingly, they act in the reverse order of action in the case of installing a new divider disk 57. To install the divider disk 57, the piston 65 in the cylinder 64 is actuated under the pressure of the oil. The lever 61 is thereby deflected so far around the bolt 60 that the adjusting cam 62 can enter against the action of the spring element 63 into the notches 58. To set the desired inclination of the cutting head, the hydrostatic bearing 21 must be under the pressure of oil. The oil, which is under pressure in the pockets 20, easily lifts the flap 5 against the action of the disc spring 18 s.
    bearing rings 17. Otherwise, the folding part 5 is barely rotated. By turning the screw 27 with the handwheel, the hinged piece 5 is so deflected about the axis of deflection 15, until the marking on the hinged piece 5 shows the desired inclination of the cutting head on the scale ring 78. At the conclusion of the oil pressure in the hydrostatic bearing, it drops again, so that the turning part 4 and the folding part 5 remain in this position relative sizes. Finally, by turning the handwheel 75, the cutting head 7 rotates further. Around the axis 12 of the cutting head, until it reaches the other position 79 described by means of FIG. 5.
    Now the oil pressure in the hydrostatic bearing 22 rises, so that the turning part 4 can turn relative to the lifting table 3. In this case, the rotation is made as long as the sharpened surface is not parallel to the plane of the sharpening machine 10 Then the oil pressure drops again and the turning part is fixed on the lifting table 3.
    By turning the handwheels 74 and 75 (Fig. 6) on the sharpening machine 10, the sharpened face is even more accurately positioned relative to the grinding wheel 9. When sharpening, the hydraulic cylinder is placed under pressure, and therefore the pump 37 through the piston rod 38 (FIG. 1) goes to the right. Thus, the wheels 35 roll over the surface 36 and the folding arms 34 change their inclination. This kinematics contributes to the fact that in the case of continuously changing its inclination of the folding arms 34, the lifting table 3 always rises more slowly. After the cutter 8 is in contact with the grinding wheel 9 in this way, the cutter 8 is sharpened to a precisely specified depth by lifting the lifting table 3 even so.
    In order to bring the edges of other cutters of the same type equally oriented to the axis 12 of the cutting head under the grinding wheel, the edges of other cutters of the same type, on another group on the cutting head, the following setting processes are carried out in the clamping device.
    The groove 55 (Figures 1 and 2) is filled with pressurized oil, whereby the cylindrical gear 53 mates with the holder b of the tool head. The cylinder 64 (FIG. 3) is also filled with pressurized oil, whereby the piston 65 raises the lever 61 so that the adjusting cam 62 exits the cut-out; Oil is also injected into cylinder 4S (Fig. 4), so that piston 4c
    is shifted to its other end position (for example, in Figure 4 to the left). Since the holder 6 of the cutting head is in conjunction with the cylindrical gear 53, the cutting head 7 and with it the separating disk turn. At the same time, it is necessary to ensure that the lift of the piston 46 does not rotate the separating disk 57 so much that: the next cutout 58 fits under the adjusting cam 62. Then the pressure oil can again be removed from the cylinder 64 and from the groove 55 and the adjusting cam 62 enters the cutout 58 again. Thus, the cutting head is counter-rotated and it can be lifted to sharpen this face. Et1 processes are repeated until all equally oriented edges of the cutter 8 of the same type are sharpened.
    To sharpen other surfaces of the edges of the cutters 8 of the same or a different type, it is only necessary to change the inclination of the cutting head 7 with a new adjustment.
    The incisal head from above looks like a circle 80. The axis 12 of the incisal head lies in the center of the circle 80 and is expressed by a point because it is perpendicular to the plane of the circle 80. The deviation axis 15 is represented by a small dash-dotted line and goes from the center of the circle 80 to the point 81 and is tilted at an angle ( f (Figures 1 and 2). Point 81 forms the center of an ellipse 82, which is only half represented. The plane, perpendicular to the deflection axis 15 and intersecting the latter at point 81, also crosses the axis 12 of the incisal head at point P and this point describes the ellipse 82 if the axis 12 is incised heads around the axis of deflection 15. In our example (FIG. 5), the axis 12 of the cutting head and the axis 15 of the deflection intersect on the surface 83 of the cutting head.
    The incisal axis 12 and the deflection axis 15 together form a plane, which rotates around the deflection axis 15, if the incisal axis 12 is deflected. Only the axis 12 of the incisal head deviates, while it does not form an angle of 30 ° C with its initial position, thereby moving the point P along the ellipse 82 to the position 84. In Fig. 5, the axis 12 of the incisal head looks like it was designed at an angle of 30 ° to its starting position vertically. Thus, the main axes 85.86 of the ellipse 87, which characterize the trajectory of the incisal head 7, will be known. These main axes 85.86 are differently oriented in space along the angle of inclination ct. The projection 88 is folded back (shown with a rare hatching) around the head axis
    85 allows you to see the inclination of the surface 83 of the blade head.
    Let us now consider first, with a horizontal cutting head, an arbitrarily oriented surface 89, which is raised above the surface 83 of the cutting head and intersects the latter on a baseline 90. Suppose that this surface should be sharpened and set vertically by tilting the cutting head 7. Since we have already described the case of inclination at an angle oL 30 of the cutting head, we assume that the surface 89 is also inclined by the p 30 relative axis 12 of the cutting head 7. As can be seen from the reclined projection, 91 right 92 gives the direction of the inclined line of the surface 89.
    To establish where surface 89 is after deviating around axis 15, select point 93 on baseline 90, which belongs to surface 89 as well as surface 83 of the cutting head, and try to find its new position after deviation. To do this, we assume that point 93 also lies in a common plane with axis 12. This common plane intersects the surface 83 of the knife head in a straight line 94. Also, this common plane intersects the surface of an ellipse 82 in straight 95.
    When the deviation around the axis 15 deviates straight 95 deviates in the plane of the ellipse 82 around the point 81. At the same time, the distance 96 between it and the straight 95 remains, because the deviation always goes tangentially to the ellipse 97. At the end of the deviation the axis The 12 cutting heads are on the plane of the circle 80 in the form of a projection 98. The axis 12 of the cutting heads intersects the plane of the ellipse 82 now at point 84, and the straight 95 turns out to be in the form of a straight 99. The plane formed by the straight 99 and having the form of a projection 98, axis 12 incisive head, crosses the surface of 83 incisors The head is in a straight 100, parallel to straight 99. The straight 100, which is nothing more than a deflected straight 94, also contains a deflected point 93, now denoted 101. Its exact position is measured by rotating the projection around line 100, which Wire itself is known for this method for another point of baseline 90, get baseline 102 of deflected plane 103
    Further, the cutting head 7 rotates around its new position, which has the form of a projection 98 of the axis 12 of the cutting head, until the plane 103 is perpendicular to the small main axis 85 of the ellipse 8.7.
    By caMfcjM, it will be perpendicular and in space and will be in the plane 104 or in the rotation of the projection as the plane 104. Thus, the plane-surface 89 is transferred to the desired position 79.
    By turning the surface 89 around the axis of rotation 24, which here coincides with the axis 12 of the cutting head / in the initial 1-position, it can be held parallel to the grinding wheel 9.
    From figure 5 it follows that the deviation angle y, which should be allotted to the hinged part 5 around the axis
    deviations in order to incline, for example, the tool head 7 through an angle of about 30, are substantially larger. From this it follows that the cabinet on the scale limb 78 should be designed, for example, so that it can be read directly from the inclination of the incisal head 7.
    Thus, this circumstance leads to an increase in the accuracy of reading
    vanilla and adjustment, and therefore sharpening the cutting head.
