Mechanical arm grabbing equipment

The utility model relates to the technical field of robot kinematics simulation, in particular to mechanical arm grabbing equipment. Comprising a mechanical arm and a grabbing assembly, the grabbing assembly comprises a tail end executor and an air suction cup, the mechanical arm grabs an object through the grabbing assembly, sucks air through operation of the tail end executor and sucks air in an air pressure bin through a vent hole, so that the air pressure bin generates negative pressure, the air pressure bin communicates with the air suction cup, and the air sucks air to generate suction force to suck up the object; compared with a traditional grabbing technology, the tail end executor can effectively grab the object with the smooth surface through air pressure suction, it can be guaranteed that the tail end executor is tightly connected with the object in the process, the grabbing efficiency is improved, and the problem that the object is prone to falling off in the grabbing process of traditional automa
