Definitions
- Such mounts are from German published patent application DE 39 19 560 A1, which shows the features of the preamble of claim 1, and British Patent 730,728. These have a synchronizing device, which by means of one, below one the tensile force between Clamp exercising rod lying, rocker arm with vertical axis a mirror symmetrical movement of the Forces jaws.
- an axis of the rocker arm is difficult to access, what a simple decommissioning of the synchronization device prevented.
- the present invention avoids these disadvantages and also allows a compact Construction.
- the invention is as in the claim 1 defined.
- a fixed middle jaw also for simultaneous Clamping several, not necessarily identical, workpieces used.
- the slide 1, 2 denote the left, or right slide, or jaw holder, one Flat clamping bracket.
- the slide 1, 2 are in a known manner so guided in the body 7 of the flat clamping bracket that they can be pushed back and forth in the clamping direction and the body itself has means (not shown) on with which he is in a certain position on the table attached to a machine tool (also not shown) can be.
- Each slide has a structure 3, 4 on the one (not shown) usually the one to be held Workpiece-adapted top jaw can be attached can.
- a cover plate 8 serves as a base for what is to be processed Workpiece and protects the inside of the flat clamping bracket against contamination from processing residues. Their position in relation to the body 7 of the flat clamping bracket can be done in a known, not shown, way by positioning pins or similar means. As described below, the cover plate 8 a third (dashed) middle structure 9 wear if several workpieces in the flat clamping bracket should be clamped in that at least one workpiece between the left and the medium build, and at least one more between the middle and the right structure is recorded.
- a spindle with an internal thread 10 and a screw 11 engaging therein serve in a known manner To do this, the two sliders, and thus the Bake to press against each other.
- a pendulum lever 24 effects the movement of the slide provided, the ends of which via beams 23 each on one of two sliders 1, 2 are articulated by the pendulum lever through the joint 25 on the beam 23, and this through the joint 26 each pinned to the corresponding slide are.
- the pendulum lever surrounds 24 the spindle 10 with enough room for one Swivel according to the maximum jaw stroke to be able to.
- the pendulum lever swings one Axis through the body 7 inserted on both sides, and in a central bore 20 of the pendulum lever engaging socket pin 22 is formed. It is without further apparent that the slide 1, 2 then mirror-symmetrical to a perpendicular to the spindle axis and going through the common axis of the socket pin 22 Level. As mentioned at the beginning, this can given tolerances of both those to be machined Workpieces such as the combination of flat clamping brackets and machine tools achieve higher precision become.
- one (dashed) immovable middle structure 9 can be an exactly symmetrical movement the slide relative to the body of the Flat clamping bracket resting transverse plane undesirable be and / or lead to mechanical over-determination.
- a firm middle structure and on both sides of it can be mechanical Determination e.g. then occur when the in Length dimension of the spindle seen on both sides the work piece is not clamped in the center jaw identical, but only within certain tolerances are the same.
- the socket pins 22 removed and thus the pendulum lever 24 are released, so that he’s no longer a Body 7 must rotate the fixed central axis.
- the socket pins 22 are preferably shorter Plug pin 21, which replaced the corresponding holes close in the body 7 without in the bore 20 of the To engage the pendulum lever.

Claims (4)
- Etau plat avec deux porte-mors entraínés pour immobiliser par serrage au moins une pièce à usiner sur une machine outil, avec un dispositif d'accouplement mécanique (22-26) des mors indépendant des moyens produisant la force de serrage et comprenant un levier pivotant (24) autour d'un axe perpendiculaire à la force de serrage, chaque extrémité de ce levier étant reliée à un porte-mors (3, 4) deplaçable dans la direction de la force de serrage de façon à ce que les porte-mors se meuvent symétriquement par rapport à un plan fixe relativement au corps de l'étau, caractérisé en ce que la force de serrage est produite par une broche (10) traversant le levier pivotant (24).
- Etau plat selon la revendication 1, caractérisé en ce qu'une pièce (23) faisant fonction de bielle est insérée entre chaque extrémité du levier pivotant et le porte-mors correspondant, cette pièce étant réunie de façon articulée avec ce levier (24) ainsi qu'avec ce porte-mors.
- Etau plat selon la revendication 2, caractérisé en ce que l'axe du levier pivotant (24) est essentiellement parallèle à la base du corps (7) de l'étau.
- Etau plat selon la revendication 3, caractérisé e3n ce que l'axe du levier pivotant (24) est formé par deux goupilles débrochables (22) engagées de deux cotés opposés dans le corps (7) de l'étau.
