    A device for the centered clamping of an annular workpiece or workpiece stack formed of a plurality of annular workpieces, to hold the same in position for the machining of the inner faces thereof, includes first and second axially aligned clamping rings for engaging opposite, radially extending end faces of a workpiece or workpiece stack positioned in a space between the clamping rings; a centering cylinder surrounding the space and having a lead-in chamfer at one edge thereof; and a clamping arrangement for moving the two clamping rings relative to one another. The clamping arrangement comprises a power device actuatable in a clamping direction; a force-transmitting arrangement extending exclusively externally of the centering cylinder and coupling the clamping rings to one another and to the power device; and an axial stop for abutting and arresting the second clamping ring when urged in the clamping direction by the power device with the intermediary of the force-transmitting arrangement, the first clamping ring and the workpiece or workpiece stack for clamping the latter between the first and second clamping rings.

    one
    The invention relates to the field of metalworking.
    A device for centering and clamping a package of piston rings on the outer surface is known, comprising a drive, a centering sleeve outside the package, two clamping rings and a mechanism for their axial movement.
    The disadvantage of this device is its low workability due to manual axial clamping.
    The aim of the invention is to expand the technological capabilities of the device.
    The goal is achieved by the fact that the device is equipped with a cup, to one of the walls of which, being a fixed stop, a centering sleeve is attached, and the mechanism for moving the clamping rings is made in the form of at least three rods parallel to each other, joined by means of a traverse mounted to the glass the possibility of axial movement by means of a drive rod, the middle rod being equipped with a linear expansion compensator, and the centering bushing - with studs, the second ends of which are included in nom from the clamping ring bore.
    The drawing shows the proposed device.
    The device consists of a centering cylinder 1 with an inlet cone 2, a disk-shaped clamping ring 3, and a clamping ring 4 in the form of a sleeve, between which a package of piston rings 5 is clamped, held in the cylinder 1 by means of a carrier 6 boron 10 of the rod 7.
    The clamping force on the rings 3 and 4 is transmitted by means of three rods 8, 9 and 10, of which two rods 8 and 9 are parallel to each other, and the rod 10 is installed along
    15 center of the device. All rods are combined by a crossbeam placed in glass 11 12. The clamping ring 4 is provided with a flange 13 connected to the rods 8 and 9, and the rod 10 carries the clamping ring 3. At the rod 10
    20, a linear expansion compensator 14 is installed, which allows a limited axial displacement of the rings 3 and 4.
    The wall is 15 cups and screwed with a working spindle 16 lathe, and
    25, the wall 17 serving as an axial stop for the clamping ring 3 carries the centering cylinder 1. In the cylinder 1, from the side of the inlet cone 2 and in the flange 13 are made
    holes 18 and 19, in which the pins 20.
    Traverse 12 is connected to piston 22 of a hydraulic or pneumatic cylinder 23 by means of a rod 21, which drains the drive device.
    To change the package of rings, the piston 22 is moved to the right so that the clamping rings 3 and 4 are withdrawn by means of. traverse the 12 l rods 8, 9 and 10 from the centering cylinder 1 and at the same time the package 5 is released by the compensator 14. A new package is inserted into the centering cylinder through the inlet cone 2 and the pins 21 are retracted left until the clamping ring 3 contacts wall 17 of the cup And, after which both clamping rings are freed from one another in the axial direction as a result of further movement of the piston 22 to the left. The described device can be easily mounted on any machine.
