    A device for facilitating the alignment of heavy workpieces at a machine table or the like, comprising a housing capable of being arranged below the workpiece at the machine table. A pendulum support is arranged in the housing so as to have a limited tilting movement to all sides and equally can be moved between a rest position and support position where it supports the workpiece. The pendulum support is arranged so that it can be selectively raised and lowered. Further, there is provided a mechanically adjustable support which is guided so that it can be raised and lowered. The mechanically adjustable support is guided in the housing between a rest position and a support position where it supports the workpiece instead of the pendulum support.

    专利说明:

    Centering and clamping devices 8 have a corresponding node 9, which is clamped in the T-shaped groove 10 of the table 1 of the machine and contains a horizontal, relative to the table 1 of the machine, a radially located lead screw 11, the lead screw 11 rotates with a wrench and develops the radially directed force necessary for centering and fastening the workpiece 6. In addition, each of the centering and clamping device 8 is equipped with a clamp 12, which is located at the lead screw 11, which rests on one end of the clamping bolt 13 a first T-shaped groove 10, and the other end presses on the clamping piece 6 by means of bolts 14 mounted in a T-shaped groove 10. Instead tsentrirukitsih manual clamping devices 8 and the hydraulic clamping devices may be used.
    The devices 7 for facilitating the installation of the workpiece b are driven by a hydraulic drive through a pressure hose 15 connected to the pump 16, to which the working fluid from the tank 17 is supplied under pressure with an adjustable valve 18 and a controlled pressure gauge 19.
    Each of the devices 7 to facilitate the installation has (Fig. 2) the housing 20, which is covered below by a board
    21 and comprises a swinging support 22, which is located inside the mechanically adjustable support 23.
    The upper end 24 of the support 22 is made in the form of a spherical segment on which the support element 25 is mounted with a flat cutter 26 for contact with the workpiece 20. The lower end 27 of the swinging support
    22 also made in the form of a spherical segment. Moreover, the surfaces of both ends 24 and 27 are constituent parts of one designated by dash-dotted circle ball surface K, whose center M lies on the longitudinal axis of the swinging support 22, made in the form of a turning part.
    The swinging support 22 rests on a cup-shaped support piston 28, the bottom of which is formed as a cylindrical shank 29 of smaller diameter and contains a pressing pressure 30, over which the lower end 27 of the swinging support 22 rolls. For the juice 30, both ends 24 and 27 of the swinging support 22 as well as the support member 28 are made of hardened steel.
    The shank 29 of the support piston 28 is located coaxially with a fixedly mounted stationary piston 31, which is screwed to the plate 21. Conducts. to the device 7 pressure hose 15 is connected through the channel 32 in the plate
    21 and channel 33 in the stationary piston 31 with both spaces between the stationary piston 31 and the supporting piston 28, forming a cavity 34 on the one hand, and the shank 29 and the bottom of the stationary piston 31, with the other side.
    The lower half of the adjustable support 23 is formed by a cylinder 35, which is movably mounted on a stationary piston 31 and forms an additional guide for a supporting piston 28, the movement of which does not depend on the adjustable support 23. Above the cylinder 35 are radially arranged in adjustable supports 23 offset by 90 relative to each other compression springs 36. These springs 36 always tend to hold the swinging support 22 in a position in which its axis coincides with the axis of the adjustable support 23. In addition, in the upper part of the adjustable support The pores 23 are mounted parallel to the axis of the compression spring 37, which tends to press down the support piston 28.
    In the upper part of the adjustable leg 23, four set screws 38 that are offset 90 relative to each other are screwed in radially. With these set screws 38, the swinging leg 22 can be turned in all directions and fixed in each position. In order to center the machined workpiece 6, the turning movements of the swinging support 22 with small dimensions and correspondingly small structural dimensions of the swinging device from the bearing 22 are narrowed down, starting from the treading part, where the setting screws 38 are located. spaces in the upper part of the adjustable support 23 and in the support piston 28.
    Adjustable support 23 has an annular top surface 39 on top, with which it can rely independently of support element 25 on the workpiece 6. The cavity between the end surface of support element 25 and flat end 26 is closed by a membrane 40 fixed on the inside of support element 35, which protects an annular cavity around the oscillating support 22 from contamination.
    The lower end of the adjustable leg 28 is inserted into an opening in the annular shape of the wedge gate 41, which is installed in the honey annular gap by the lower part of the stationary piston 31 and the housing 20 with the possibility of vertical movement and is preloaded downwardly by the compression spring 42 to the wedge gate 43.
    movement in the housing 20 in the radial direction relative to the common axis of the adjustable support 23, the support piston 28 and the stationary piston 31 and has a wedge surface 44 on top which contacts the wedge surface of the wedge gate 41. For movement of the wedge gate 41 there is a spindle 45 installed with the possibility of vrgitseny, but without axial movement. The lead screw 45 is equipped with 1 scale 46, and in case 20, risk 47 is performed.
    The device works as follows.
    Before starting the installation of the workpiece, the support piston 28 occupies the lowest position, in which its shank 29 is located directly at the bottom of the stationary piston 31. Accordingly, the swinging bearing 22 occupies the lowest position and its end face 26 is located below the end surface 39 Consequently, the workpiece 6 after it was lowered - in the general case by a crane, is located on the end surface 39. Then the working fluid from the pump 16 through the pressure hose 15 and the channels 32 and 33 is fed into the The space between the stationary piston 31 and the support piston 28 with the shank 29, so that the support piston 28 together with the swinging support 22 rises, and the swinging piston 22 reaches the position indicated by the dash-dotted line in FIG. 2 in which it lifts the workpiece 6 from the end surface 39 of the adjustable support 23 through the support element 25 until it fits onto the claws of the 12 centering and three pressing devices 8. In the same way, the work of the other devices 7 located under the workpiece 6 is carried out. limited to preset tacks 12 and up to several mm. In this case, as a rule, the lead screws are set relative to the part in such a way as to prevent undesirable movements of the workpiece in horizontal directions.
    Then, the workpiece 6 is centered about the axis of rotation of the table 1 of the machine by its horizontal movements. This happens either due to the rotation of the driving screws 11 of the centering and clamping devices 8 or in case
    centering spans are used without such spindle screws, using the set screws of devices 7. In both cases, the swinging supports
    22 perform pivoting movements in the desired direction. If necessary, the workpiece 6 is still aligned at a height. Adjustable propeller is rotated by turning the lead screw 45 for one or several devices
    23 with part 6 is set higher or lower. As soon as the workpiece 6 is fully aligned, the adjustable supports 23 of all devices 7, by corresponding twisting of the drive screws 45, move upwards until they hold the parts 6. In this case, the swing supports 22 of all devices 7 are lowered and completely unloaded, While the clamping bolts 14 of all the centering and clamping devices 8 are tightened.
    On a scale of 46 and corresponding. The risk 47 on the housing 20 can be counted, the height of the adjustment of the adjustable support 23.
    Such an embodiment of the device significantly improves the performance and accuracy of processing due to easier and more accurate alignment of the part.
