Detailed description of the invention

Referring to Fig. 1, show robot clamp of the present utility model.

Described robot clamp comprises fixed frame 11, and this fixed frame 11 can be quadra (square or rectangular), and this fixed frame 11 can be affixed on robot arm, so that the application's robot clamp is fixed on robot arm.

The both sides outer rim of described fixed frame 11 is fixed with respectively a clamping cylinder 12, and the body of described clamping cylinder 12 is laterally fixed on described fixed frame 11, and its piston rod stretches out along the horizontal activity of fixed frame.

The lower end, both sides of described fixed frame 11 is fixed with respectively a fixed support 13 and slides and is arranged at the sliding support 14 of fixed support 13, and the piston rod free end of the clamping cylinder 12 of fixed frame 11 both sides is connected to described sliding support 14 by a clamp connection 121 respectively, drive sliding support 14 to slide on fixed support 13 with the stretching motion by clamping cylinder 12.
