Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1, the utility model relates to a large stroke single action type bar grabbing device, include: the device comprises a connecting seat 1, a main frame 2, a cylinder 3, a piston rod 4, a push plate 5, a linear guide rail 6, a U-shaped movable seat 7, a fixed serrated plate 8, a limiting block 9, a linear bearing 10, a movable block 11 and a movable serrated plate 12.

The gripping device in this embodiment is mounted on six axes of the robot. The connecting seat 1 is fixed on a six-axis flange of the robot through bolts; the main frame 2 is connected with the connecting seat 1 through bolts, the end surfaces of the main frame and the connecting seat are attached, and the main frame and the connecting seat are symmetrically fixed on the axis; the end face of the cylinder 3 is fixed on the main frame 2 and is fastened through a bolt; the end surface of the piston rod 4 is contacted with the push plate 5 and is fastened through a screw; the push plate 5 and the U-shaped movable seat 7 are vertically connected, and the screw is tightly fixed; the linear guide rail 6 is fixed at the bottom of the main frame 2 through bolts; the linear bearings 10 are arranged on the linear guide rail 6 and can freely slide, and the U-shaped movable seat 7 is fixed on the two linear bearings 10 and keeps a certain distance; the movable block 11 is arranged on the U-shaped movable seat 7 and is fastened through a bolt; the limiting block 9 is also fixed on the U-shaped movable seat 7 and is on the same plane with the movable block 7; the fixed serrated plate 8 is installed on the fixed claw 13 of the extending part of the main frame 2 with the sawtooth outwards and faces the movable serrated plate 12, and the movable serrated plate 12 is fixed on the movable block 11 and fastened by bolts.
