    专利说明:

    1 The invention relates to a machine tool industry, in particular to clamping devices for fastening cylindrical parts.
    The aim of the invention is to improve the reliability of fastening parts of different diameters by matching the clamping force with the size of the product, since the clamping force acts on the product at an angle that decreases with increasing, tilting the lever and due to simple synchronized movement of the clamping levers.
    FIG. 1 shows a clamping cartridge of a general view; FIG. 2 shows section A-A in FIG. 1, in FIG. 3 shows a section BB in FIG. 2
    The body 1 of the cartridge is located on the stand of the feeder (not shown). The cartridge contains three clamping lever 3, installed with the possibility of rotation around the pins 4 parallel to the axis 5 of the cartridge. At the outer ends of the levers 3, the protrusions in the form of rollers 6 mounted on the axles 7 are erected. The length of the clamping levers 3, i.e. The distance 8 from the rollers 6 to the axis 9 of rotation of the lever 3 is greater than the distance 10 from the axis 9 of rotation to the axis 5 of the cartridge. I
    The axis 11 of rotation of the rollers 6 rotates, passes the path 12, i.e. the roller 6 of each clamping lever 3 rotates past the axis 5 of the cartridge.
    Levers 3 are rigidly connected to gears 13 that engage with the central gear wheel.

    14, mounted to rotate about axis 5. One of the gear 13 is connected to a rack 15 connected to a hydraulic cylinder rod (not shown). The roller 16 provides a constant contact of the rail 15 with said gear 13. In the housing 1, there is an elastic axial stop, made in the form of several support bars 18 interconnected in the center 17 of the cartridge, with guide fingers 19, spring-loaded springs 20. The slats 18 are connected to the fingers 19 by means of hinges 21. In order for the clamping rollers 6 of the levers 3 to be able to rotate inwards as far as possible to clamp the product of as small a diameter as possible, on the support bars 18 near the center of the cartridge there are recesses 22, which extend in the direction of rotation ota clamping levers 3.
    The cartridge works as follows.
    The rake 15 moves from the hydraulic piston rod in the axial direction and rotates one of the gears 13 associated with it, which transmits rotation to the central gear 14, rotating 1 ;; rotates about the axis 5 of the cartridge, transmitting rotation to the remaining gear 14. The latter rotate After that, the clamping levers 3 are turned around the pins 4, while the part 23 or 24 is clamped by the rollers 6.
    Spring-loaded springs 20 through the fingers 19 of the strap 18 of the stop provide a reliable contact of the clamping parts 23 and 24 with the rollers 6, thereby centering the specified parts when transferred to the clamping cartridge.
