    In a device for clamping a workpiece, such as an undressed casting, so that various surfaces of the workpiece can be mechanically worked, a platform having a support surface for the workpiece is pivotally mounted on a horizontal first axle located below the support surface. The first axle is pivotally mounted in a first cup-shaped housing which, in turn, is mounted for rotation about a vertically extending second axle. The first housing is pivotally supported within a second cup-shaped housing which is secured by swivel arms to a horizontal third axle located above and extending normally of the first axle. With the workpiece located on the support surface of the platform, the position of the surface to be worked is sensed to determine any deviations from a nominal position and by pivoting the platform about the three axles the surface can be precisely located for the working operation.

    (54) DEVICE FOR ORIENTATION AND CLIPPING PREPARATIONS UNDER MECHANICAL PROCESSING The invention relates to the field of machine-tool construction. A device for orientation and clamping of workpieces during mechanical processing is known, which comprises a platform rotatably mounted around three different axes and a clamping mechanism. The purpose of the invention is to expand the technological capabilities of the device. This goal is achieved by having two cases housed in one another. can be rotated around axes placed in the same plane perpendicular to each other, with the axis of rotation of the outer casing located horizontally above the surface The base of the platform, which is installed in the inner case, can be rotated relative to it on the axis, placed perpendicular to the plane of arrangement of the two other axes. Each of the axles is provided with an actuator, a measuring mechanism associated with it, and the axes of the bodies are housed in supports made in the form of three-point sliding bearings, which are equipped with a hydraulic injection piston. FIG. 1 schematically shows a general view of the device; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 shows a section B-B in FIG. one; in fig. 5 is an embodiment of the proposed device {G in FIG. 6, 7 shows a device with a horizontally mounted platform for leveling the upper surface of the workpiece; in fig. 8, 9 shows a device, with a vertically mounted platform for leveling the sides of the workpiece. The device consists of two buildings 1 and 2, placed one in the other with the possibility of rotation around the axes 3 and 4, which are placed in one. plane and mutually each other, with the axis 3 of turning the outer case horizontally above the surface of the platform 5, which is installed in the inner case 2 rotatably relative to it on an axis 6 located perpendicular to the plane of the axes 3 and 4. Each of the axes is equipped with the drive 7, which can be hydraulic rotating with the drives, as well as other types of hydraulic, electric and pneumatic servo drives and connected to the axes by the measuring mechanisms. The axes 3 and 4 of the housings are housed in supports made in the form of three-point sliding bearings 8, of which they are provided, placed in the cylinder 9., with a hydraulic pressure piston 10 that presses on the outer diameter of the bearing 8.
    When turning on the piston 10, a small pressure is applied which allows the axis to be moved in the bearing 8, and with a large pressure in the cylinder 9, the axis is clamped in the bearing 8.
    The platform 5 is equipped with a linear servo 11, which is rotatably fixed on the bracket 12 and connected to a linear sensor 13. To bring the platform 5 into a vertical position, the servo 11 when rotating is disconnected from the platform 5.
    The blank 14 is mounted on the supports 15 of the platform 5 and clamped by the clamp 16. The blank can be mounted on the platform directly and secured by means of a magnet. . The device works as follows.
    The blank 14 is placed on the platform 5 and clamped by the clamp 16. Then the actual position of the blank 14 is determined at at least two selected points with one or several sensitive elements of the sensor 13 of the measuring device, and the deviation from the desired position is corrected by rotating the platform 5 relative to the axes 3, 4 and 6. Measuring the deviation from a predetermined position is realized by the sensitive elements of the sensor at a distance, in the optimal case - inductively, and it is also possible to use others. GIH measuring methods.
    In order to be able to process the surface B of the workpiece 14, it must be installed perpendicular to the tool axis. This happens, as shown in figs, b and 7, due to the fact that the points M and Mj on the X axis will first be felt. The measured difference along the Z axis (Z - Z) uZ will be converted by using the distance between the measured points a the computing device at an angle jj for the axis 6. By means of electro-hydraulic control and the rotary actuator, this value is converted into a rotating movement of the axis 6, and the execution is confirmed via selsyn 17.
    Then, the measured M 5 and M4 currents will be touched along the Y axis and the correction of the position according to the method already described will be made by rotating the platform 5 around the axis 3 in accordance with the angle of correction p.
    After adjusting the position, the exact surface size is determined.
    into the workpieces by means of the sensing element of the sensor 18, starting from the fixed point of the Z axis and processing is carried out at the now constant size.
    When machining the side surfaces C D, E, F of the workpiece 14 (see Figs. 8 and 9), the position is corrected with a vertically mounted platform, for which it will be rotated relative to axis 3 by 90® relative to the zero position. Straightening and subsequent processing of each side is carried out separately, with the sides D, E, F being turned into the straightening position and working position successively when the platform 5 rotates around axis 4, each time
    90
    The measurement of the actual position of each of the sides is made as already described and shown in FIG. 8 and 9, first along the two measured points M and M along the X axis, followed by adjusting the position, which is the rotation of the platform 5 around the axis 4 according to the angle X, then along the two measured points M and M 4 along the Y axis with the subsequent adjustment of the position, which is the rotation of the platform around Axis 3 in accordance with the angle j3
    But for milling and grinding profiles, shoulders, etc. and for applying holes, a complete adjustment of the position of the workpiece is necessary. This is feasible, for example, when the platform 5 is horizontal, if in addition to the described straightening of the surface to be bathed orthogonal to the milling axis, the platform rotates around axis 4 and moves it along the X and Y axis, which. requires the placement of the described device on the cross slide with the appropriate servo drives and position indicators.
    If the machining tool is located on the cross slide, then an adjustment in the X- and Y-axis directions can be made by moving the tool in the mentioned directions from the initial position by an amount corresponding to the difference between the specified and actual positions of the workpiece.
