Industrial robot grabbing device

The utility model relates to the field of industrial robots, in particular to an industrial robot grabbing device which comprises an installation base. A fixing disc is arranged at the lower end of the mounting base, and a plurality of clamping arm assemblies are hinged to the lower end of the fixing disc in a circular array mode; the clamping arm assembly comprises two first clamping arms which are connected end to end, and the first clamping arm at the upper end is obliquely arranged outwards relative to the fixing disc. A plurality of first clamping arms are arranged on the base, a plurality of second clamping arms are arranged on the inner sides of the first clamping arms, first electric telescopic rods are arranged between the first clamping arms and the second clamping arms, the minimum range allowed by clamping of the device is achieved by changing the inclination angles of the first clamping arms, and then the second clamping arms are driven by the first electric telescopic rods to move inwards; and m
