The invention provides a hole making system for an intelligent AGV lifting robot. The hole making system comprises mecanum wheel assemblies, a vehicle body, a laser emitter, a positioning camera, a test piece table, a six-axis robot, an end effector, a laser scanner, a grating ruler, a lifting driving device, self-adaptive supporting legs, a lifting platform and a linear guide rail. According to the hole making system, the mecanum wheel assemblies are driven by a servo motor and a storage battery, so that omni-directional movement is realized, and meanwhile, an external power source is not required to be connected; the laser emitter and the positioning camera are used for positioning and measuring, so that accurate positioning and position deviation feedback are realized; in the hole making process, the three self-adaptive supporting legs are used for forming a triangular stable support for the vehicle body so that the robot can overcome the influence caused by uneven ground plane, andhole making precision is guaranteed; accurate lifting of the six-axis robot is completed by the lifting mechanism and a grating ruler measuring control system, so that the working space of the robotis greatly expanded; and The hole making system has the advantages that the assembling quality and efficiency of an aircraft can be greatly improved, and meanwhile, assembling cost of the aircraft isreduced.
