Detailed Description

The technical solution of the present invention is further explained by the specific embodiment with reference to fig. 1 to fig. 2.

The special antiskid gripping device for the piston shown in fig. 1 comprises: fixed plate 4, double-layered jar 2, first holder 5, second holder 7 and elasticity clamp splice 10, the welding of fixed plate 4 top is provided with the stand 3 that upwards extends, the top welding of stand 3 is provided with flange 1, and flange 1 is connected with robotic arm, carries out the removal of flange 1 and fixed plate 4 through robotic arm.

The clamping cylinder 2 is horizontally arranged at the bottom of the fixing plate 4 and is fixed by screws. The bottom surface of the clamping cylinder 2 is provided with a rubber cushion block 8, so that the problem of impact with the piston 12 is avoided. The rubber cushion block 8 can be fixed on the bottom surface of the clamping cylinder 2 by adopting an adhesive, and the structure is firm.

The first clamping seats 5 are L-shaped bent plates, the first clamping seats 5 are symmetrically arranged at two ends of the clamping cylinder 2, and the first clamping seats 5 are driven by the stretching of the clamping cylinder 2. The clamping cylinder 2 is controlled by an electromagnetic valve and can be driven by a PLC (programmable logic controller), so that the automatic control is facilitated.

As shown in fig. 1, the second clamping seats 7 are respectively arranged at the bottom of the first clamping seat 5, the second clamping seats 7 are inverted L-shaped bent plates, the first clamping seat 5 and the second clamping seat 7 are connected through bolts 6, and first waist holes corresponding to the bolts 6 are transversely arranged on the first clamping seat 5, so that the second clamping seats 7 can be conveniently adjusted, the distance between the two second clamping seats 7 can be changed, and the pistons 12 with different diameters can be adapted.
