Definitions
- Pair of grippers especially one
- the invention relates to a pair of grippers according to the preamble of claim 1.
- the invention is therefore based on the object, while avoiding the disadvantage mentioned, of creating a pair of grippers of the type mentioned, which does not laterally shift its figure axis when the gripped workpiece is moved.
- the execution of the pair of grippers according to claim 2 leads in a simple yet expedient manner to a reliable detection of cylindrical sections of the workpiece, that according to claim 3 to complete gripping sym et rie.
- a flatness of the inner surfaces of the three fingers of the pair of grippers is only necessary insofar as their contact with the workpiece moves over these inner surfaces when the workpiece is pushed through the pair of grippers.
- the invention is based on an exemplified by the preferred embodiment of the drawing gripper pair according to the invention in detail it ⁇ explained. In principle, it shows this version
- FIG. 3 shows a composition of FIG. 1 (dash-dot repeated) and of FIG. 2
- the pair of grippers 10-20 consists of a fork-shaped gripper 10 with two fingers 10.1 and 10.2, which are spread over 60 °, and which has a circular, conical, that is, rot at ion symmetry, workpiece 14 with several different diameters from a non-forked gripper 20 holding the workpiece 14 in the forked gripper 10 with a single finger 20.1.
- the three straight fingers 10.1, 10.2 and 20.1 are arranged at 60 ° to one another, so that they form a substantially triangular, equiangular space, through the center of which the virtual straight figure axis 12 of the workpiece 14 passes, which lies in a plane of symmetry 15 with respect to whose holding gripper 20 and the receiving gripper 10 are designed in mirror image without the third finger 10.1 and can be moved at the same time and evenly, both parallel and perpendicular, namely rectilinearly, to the plane of symmetry 15 to which the third finger 10.1 of the forked gripper 10 is perpendicular, while the other two fingers 10.2 and 20.1 converge symmetrically at a distance from the third finger 10.1. -
- the lengths of the three fingers are dimensioned so that they close together when the space is closed.
- the mutually facing inner surfaces 10.1.1, 10.2.1 and 20.1.1 of the three fingers 10.1, 10.2 and 20.1 each lie in a plane perpendicular or inclined at ⁇ 30 ° to Plane of symmetry 15 and tangent to a diameter of the ⁇ piece unit 14 along three in the intermediate space generatrices was ⁇ nes circumference if the gripped workpiece section k re is zy li ndr is CH, or angspunk three Umf t s, if he z. B. is conical.
- These three Be r Uh approximately lini s (in the drawing as points visible) form with the figures ⁇ axis 12 of the workpiece 14 each have a plane of contact, in pairs enclose an angle of 120 °.
- FIG. 1 shows a small diameter of the circumference of the workpiece 14, the three gripping r 10.1, 10.2 and 20.1 being moved together to form a correspondingly narrow space.
- the axis of the figure 12 of the workpiece 14 is relatively close to the inner surfaces 10.1.1, 10.2.1 and 20.1.1.
- FIG. 3 shows the relative change in position of the grippers 10 and 20 with respect to the spatially fixed figure axis 12 of the workpiece 14 during a transition between the states shown in FIGS.
- the two fingers 10.1 and 10.2 of the receiving gripper 10 can extend over more than 60 °, e.g. B. 75 ° to 80 °, be spread by halving the opening angle of the spread through the shifting line 16 and while maintaining the mirror image of the arrangement of the single finger 20.1 of the holding gripper 20 and the shifting line 17 with respect to the plane of symmetry 15.
