Definitions

the invention relates to a toggle clamp device for gripping and Clamping sheets or the like, in particular for use in Body construction of the motor vehicle industry according to the preamble of claim 1.
DE 296 12 324 U1 also has a toggle lever tensioning device, preferably for embossing, marking, flanging, clinching, punching, punching or Joining in sheet metal processing for the body shop described, the two clamping arms are rotatably attached to a stationary console and each have their own adjustment element.
the lower clamping arm is fixed with connected to a cylinder for actuating the upper clamping arm. With that the Opening area of the clamping device solely by the rotary movement of the upper clamping arm determined.
the lower clamping arm can only be used in limited Way together with the cylinder that operates the upper tension arm, be pivoted.
This device also has space for Means of production and for the loading and unloading of workpieces are very limited.
the invention is based on the object, a toggle lever tensioning device propose that these problems be largely addressed.
the toggle lever tensioning device is particularly characterized by this characterized that the pivoting movements of the clamping arms are guided are, so that the movements are carried out accurately and the Repeatability, especially the end position is guaranteed.
This forced operation is arranged in stationary backdrop walls Link guides for one in the tensioner housing with the Piston rod connected bolt reached.
the invention provided that in addition also the entire tensioner housing on which the two clamping arms are articulated between the stationary Scenery walls is pivotable about an axis of rotation from the work area.
the axis of rotation is preferably at the end facing away from the work area of the single cylinder, so that the entire tensioner housing with the cylinder, the articulated levers and the clamping arms the work area can be pivoted.
Scenery guides arranged, with a scenery guide, preferably runs vertically and with the movement of the piston in this link guide only the clamping arms perform a swiveling movement.
first Backlit guide subsequent backlit guide provided, which is preferably in runs at a certain angle to the first backdrop guide.
the movement of the lower tensioner has finally proven to be beneficial by a stop and / or an adjustable stop screw into the Limit clamping position.
This stop is particularly attached so that the lower clamping arm has a precisely defined one during the clamping process or horizontal receiving plane for the sheets.
the tensioner housing 1 is firmly attached to it arranged pneumatic cylinder 2 between the two backdrop walls 3rd arranged.
the backdrop walls 3 are firmly connected to the base plate 24 and can be attached to the respective location of the body shop become.
the two backdrop walls 3 are on the spacer 4 Spaced so that the tensioner housing 1 between the link walls 3rd has sufficient freedom of movement.
the one with the tensioner housing 1 connected cylinder 2 is rotatable by means of the bolt 20 in the two Backdrop walls 3 stored.
the pivoting movement of the tensioner housing 1 around the bolt 20 is determined by the bolt 19, which is in the link guides 27 and 28 of the backdrop walls 3 is slidably guided.
the bolt 19 is at the upper end of the Piston rod 26 arranged so that it with the movement of the piston 25 in Area of the link guide 27 a linear movement and in the area adjoining obliquely arranged slide guide 28 additionally a lateral one Movement, which then according to the pivoting movement of the clamping housing 1 Fig. 5 leads.
an elongated adapter 10 is fixed at the upper end connected.
the adapter 10 has an elongated hole 29 in which a transversely or horizontally arranged bolt 17 is slidably arranged is.
a transversely or horizontally arranged bolt 17 is slidably arranged is.
At the upper end of the adapter 10 is another transverse to the longitudinal axis of the Adapter 10 lying bolt 16 attached as an axis of rotation for a tab 13, the Attacks articulated on the upper clamping arm 5 via a bolt 15.
the tension arm 5 is mounted on the shaft 11 on the tensioner housing 1 and is by the Movement of the piston rod 26, the adapter 10 and that as an articulated lever trained tab 13 pivoted.
the one with the Shaft 12 is also mounted on the tensioner housing 1 as an axis of rotation, which engages Tab 14 with the pin 18 as the axis of rotation.
the other end of the too designed as an articulated lever tab 14 engages over the bolt 17 in the Elongated hole 29 of the adapter 10 and is in the case of concerns on the upper or lower End of the slot 29 actuated.
a replaceable pressure piece 7 and on the lower clamping arm 6 interchangeable support piece 8 is provided to fix the lower Clamping arm 6 in a predetermined, preferably horizontal, clamping position is a stop 9 on the tensioner housing 1 and / or 6 on the lower tension arm adjustable stop screw 22 arranged.
FIGS. 2 to 5 show different positions I to IV of the tensioning arms 5, 6, the articulated lever and the tensioner housing 1 depending on the position of the piston 25 shown in the cylinder 2.
the piston 25 At the clamping position I according to FIG. 2 the piston 25 in the uppermost position, the two tabs 13 and 14 are each above the dead center, which creates a tension lock results.
piston 25 is about 1/3 compared to position I. moved down.
the adapter 10 has now the tab 13 on the Dead center moves away and the upper clamping arm 5 is around a corresponding Amount pivoted upward about shaft 11.
the tab 14 is still not been moved.
the bolt 17 attached to it has one Relative movement performed in the slot 29 of the adapter 10 and is on upper end of the elongated hole 29.
FIG. 5 shows the upper clamping arm 5 in the top and lower clamping arm 6 in the lowest swivel position. Beyond that additionally the tensioner housing 1 with the tensioning arms 5, 6 attached to it pivoted the bolt 20 out of the work area. This additional Pivotal movement is achieved in that the bolt 19 in the Link guide 28 (see FIG. 1) has been guided diagonally downward to the right.
