    An apparatus for dressing and adjusting a dished or plate-shaped grinding wheel at a tooth flank-grinding machine for a gear has an adjustable grinding wheel support at which there is mounted the grinding wheel, and a dressing carriage which is adjustable radially with respect to the grinding wheel. Arranged at the dressing carriage diametrically opposite the work location at which there is effective the grinding wheel upon a tooth flank, is a dressing tool for the working or effective end surface of the grinding wheel and a dressing tool for the outer jacket or peripheral surface of the grinding wheel as well as a feeler for scanning the working end surface. The adjustment direction of the grinding wheel support encloses an acute angle gamma with the adjustment direction of the dressing carriage, this acute angle coinciding with the inclination of the rear surface of the grinding wheel, and the grinding wheel axis encloses with the adjustment direction of the grinding wheel support the complementary angle 90 DEG - gamma . The adjustment path of the dressing carriage in relation to the adjustment path of the grinding wheel support satisfies the equation: c:b=2-cos gamma .

    2. The device according to claim 1, wherein the second right-hand tool is installed with
    possibility of movement perpendicular to the direction of carriage movement.
    I
    The invention relates to mechanical engineering and can be used to manufacture precision gears.
    A device is known for straightening the end and periphery of a disk-shaped wheel mounted on an inclined spindle of the movable headstock of a gear-grinding machine, comprising a bracket with right-handed tools and a carriage that is radially movable and coupled by a control system with a drive of the headstock 1
    However, this device is complicated due to the presence of a special system for controlling the ratio of movements of the headstock and carriage.
    It is also known a device for straightening the end and periphery of a disc wheel mounted on an inclined spindle of the movable headstock of a gear grinding machine, comprising a bracket with two right-hand tools, one of which is mounted to move the grinding wheel along the working face in the radial direction as well as the mechanism of relative displacement of the headstock and bracket C2.
    However, the known device is relatively difficult to operate because it is necessary to set up the right tools for setting up the machine.
    The purpose of the invention is to simplify the setting of the wheel straightening device as it is worn.
    This goal is achieved by the fact that the device for dressing the end and periphery of the disc wheel mounted on the inclined spindle of the movable headstock of a gear grinding machine, containing a bracket with two right-handed tools, one of which is mounted for movement along the working end of the grinding wheel in radial alignment, is equipped with a movable in the radial direction, a carriage kinematically connected with the drive of the movement of the headstock, the bracket being fixed to said carriage.
    The second right tool can be mounted to move perpendicular to the direction of movement of the carriage.
    FIG. 1 shows the proposed device together with the headstock of a gear grinding machine; in fig. 2 device designs; in fig. 3 is a diagram of the editing of the disc circle; FIG. 4 shows the layout of a gear grinding machine with an offer of a device for dressing each grinding wheel.
    The device contains a bracket 1 with two right-handed tools 2 and 3. The bracket 1 is fixed on the carriage 4. The base 5 of the carriage 4 is mounted on the plate 6 of the machine. A headstock 7 is connected to the same slab, which is mounted for movement along guides 8. A drive 9 serves to move a headstock 7. A carriage 4 is connected to this drive by means of, for example, gears 10-12. The spindle 13 serves to move the headstock 7, and the spindle screws 14 are used to move the carriage 4. The headstock 7 has an inclined spindle 15, the angle of inclination of which is determined by the parameters of the gear wheel 16 to be ground. The disc wheel 17 is fixed to the spindle 15, the working end 18 and the periphery 19 are immigrated, and the ENBJe is subjected to periodic straightening. To edit the working end 18, use the right tool 2, which is installed with the ability to move in the radial direction in arrow A. To edit the periphery 19 of the circle 17, use the right tool 3, which can be installed with the possibility to move along arrow B, i.e. perpendicular to the radial direction The carriage 4 can move in the radial direction in the direction of arrow B, and the headstock 7 in the direction f. The angle between these directions is -d-. The angle of inclination of the spindle 15 is equal to 90 ° - g.
    In the device, a probe 20 may be used, which is in contact with the 50 working end 18 of the circle 17, the contact element 21 of which is connected to the drive control system 22 of the headstock 9.
    The device works in a 55 way.
    When the wheel 17 is worn, which can be fixed, for example by the probe 20, the actuator 9 is turned on, providing discrete movement of the headstock 7 in the direction of the arrow D and carriage 4 in the direction of the arrow B, and the ratio of the amount of movement of the carriage to the amount of movement of the headstock is 2 cos y. The right tools 2 and 3, moving along the plates A and B, straighten the butt and the periphery of the circle 17. At the same time, the working position of the working section of the circle 17 relative to the grinding gear 16 is achieved.
    Thus, due to the presence in the proposed device of a carriage installed with the possibility of moving in the radial direction by an amount associated with the movement of the headstock in a specified manner, the contact of the standard wheel with the gear to be processed is not suitable for removing a circle of a certain layer during dressing and reducing sizes. This greatly simplifies the process of setting up the device for operation in a wide range of dimensional wear of the grinding wheel.
