    Der Hochdruckspanner besteht im wesentlichen aus einem Schraubstock mit eingebautem Kraftverstärker, der es erlaubt, die Backen, die das Werkstück festhalten, mit hoher Kraft zusammenzudrücken. Die Anordnung ist derart getroffen, daß sich die bewegliche Backe (11) in der zurückgezogenen Stellung des Schlittens (10) über dem Kraftverstärker befindet, der im Schraubstockkörper (1) zwischen dem Widerlager und der Schraubspindel angeordnet ist. Die Kraftübertragung von der Schraubspindel auf den Schlitten erfolgt über die Spindelmutter (21), die sich in einem Ansatz (9) des Schlittens befindet und wobei auf die bewegliche Backe in der Spannstellung ein schräg nach vorne und unten gerichteter Zug ausgeübt wird. Diese Anordnung ergibt ein günstiges Verhältnis zwischen der Spannweite und der gesamten Baulänge und trägt insbesondere auch dazu bei, eine Verkantung der beweglichen Backe in der Spannstellung auszuschließen oder doch zu vermindern.

    The invention relates to mechanical engineering, namely to high pressure terminals, i.e. to machine clutches with an amplifier.
    The purpose of the invention is to reduce the size of the clip by ensuring an optimal ratio between the width of the cheek divorce and the total clip length.
    Fig, 1 shows the clip, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a section b-B in FIG. I.
    High pressure clamp

    It is a vice. Massive and solid 15 lem 36, which is located in part 22
    The case of a vice has the parallelepiped form. Recesses 4 are provided on the adjoining plane 2 and on the lateral planes 3, which allow the mounting means of the high-pressure clamp to be placed on the working table of the machine.
    At one end of the housing 1, a fixed cheek 5 is mounted, which is held by several screws 6. A fixed cheek 5 enters a groove 7 of the corresponding shape with a wedge-shaped protrusion 8 in order to bear the pulling force. The protrusion 8 is made only along the edges, while the middle part is free, Q is for the protrusion 9 of the hollow slide 10. The slide carries a movable cheek 11 and is located under the upper edge of the body 1 in the longitudinal cavity 12 of the body 1. In the side walls of this cavity 12 you 20

Between the amplifier 36 and the lead screw 23 is placed the pressure element 37, the package 38 of the Belleville springs and the plunger 39, fastened with a screw 40.
    The clamp works as follows.
    The screw rotates the screw with the handle. With moderate resistance on the lead screw 23, the ball 29 rotates through the nut 31 to the liner 34 and the lead screw 23. Since the latter moves the movable cheek P. through the slider 10, then upon contact of the cheeks 5 and 11 with my clamping part, the feed screw feed resistance 23 increases and the ball 29 exits hole 30. It starts

    The guides 13 and 14 are filled, in which the rotary screw 28 sprays the slider 10 into its side slats 15.
    On the slider 10 in the transverse recess 16 is placed a spring 17 fixed by two screws 18 and serving as a supporting element for the movable cheek I1 fixed on the slider 10 by screws 19.

    The slider 10 has a longitudinal hole 20, having an internal thread in the protrusion 9, which forms the uterine nut 21. The remaining part 22 of the longitudinal hole 20 has a slightly larger diameter. In the forward position of the movable cheek 1I, part 22 encloses a part of the lead screw 23 installed in the uterine nut 21. At the end of the housing 1, a thrust bearing 24 is fixed on the side of the movable cheek 11 24. A sleeve 25 is installed on the thrust bearing Ja 24, which covers the device

    relative to the intermediate sleeve 31, and the pressure bolt 35 is pressed into the amplifier 36. In this relatively large way of the pressure bolt 35 corresponds to a smaller way of the pressure element 37, which with a correspondingly increased force through the package 38 of the belleville springs presses on the plunger g 39 23..

    High pressure, occurring in the amplifier 36, causes longitudinal movement of the lead screw 23, which is transmitted through the uterine nut 21 to the protrusion 9 of the slider 10. Since the protrusion 9 is displaced relative to the working surface of the movable cheek P toward the fixed cheek 5, a pulling force occurs on the movable cheek 11, directed obliquely forward and downward, which prevents or at least reduces the rotation of the movable slal
    setting and limiting clamp pressure.
    A threaded screw 28 can be rotated by means of a handle (not shown) inserted into the hole 26 through the cross roller 27. The spring-loaded ball 29 enters the hole 30. The intermediate sleeve 31 through the lead screw 32 located in the oblong hole 33 is connected to the connecting sleeve 34 , made in one piece with the lead screw. The pressure bolt 35 is in contact with
    longitudinal drilling 20 between the thrust bearing 24 and the lead screw 23 under the movable cheek 11 in its retracted position. Between the amplifier 36 and the lead screw 23 is placed the pressure element 37, the package 38 of the Belleville springs and the plunger 39, fastened with a screw 40.
    The clamp works as follows.
    By means of the handle, the threaded screw 28 is rotated. With moderate resistance on the lead screw 23, through the ball 29, rotation is transmitted through the nut 31 to the sleeve 34 and the lead screw 23. Since the latter moves the movable cheek P. through the slider 10, then upon contact of the cheeks 5 and 11 with the clamped part, the resistance of the lead screw 23 increases and the ball 29 leaves the hole 30. It starts with - ji ui.rw4- (1 rio j t. 1 n / i jvj udHriricit;
    with the rotation of the threaded screw 28 from
    relative to the intermediate sleeve 31, and the pressure bolt 35 is pressed into the amplifier 36. In this relatively large way of the pressure bolt 35 corresponds to a smaller path of the pressure element 37, which with a correspondingly increased force through the package 38 of the belleville springs presses on the plunger 39, which abuts against the driving screw 23 .
    High pressure, occurring in the amplifier 36, causes longitudinal movement of the lead screw 23, which is transmitted through the uterine nut 21 to the protrusion 9 of the slider 10. Since the protrusion 9 is displaced relative to the working surface of the movable cheek P toward the fixed cheek 5, a pulling force occurs on the movable the cheek 11, directed obliquely forward and down, which prevents or at least reduces the rotation of the movable cheek 1 1 when a pulling force occurs.
    If spring elements (not shown) are provided in the region of the protrusion 9, which press on the protrusion 9 relative to the housing 1 upwards, the side rails 15 of the guides always abut the upper guides 13, which excludes rocking movement.
