Numerical control milling machine tool setting device based on machine vision

A numerical control milling machine tool setting device based on machine vision solves the problem that a milling cutter tool setting mode has the advantages of being long in consumed time, low in efficiency, poor in applicability and the like and becomes a bottleneck affecting production efficiency. Comprising a positioning sleeve, a centering chuck is connected in the positioning sleeve in a sliding mode, a rectangular sliding groove is formed in the positioning sleeve, a base capable of moving up and down is connected in the rectangular sliding groove in a sliding mode, a containing groove is formed in the position, right opposite to the positioning sleeve, of the base, and a Z-axis setting device is installed in the containing groove. A first sliding block capable of sliding left and right is connected to the base in a sliding mode, a telescopic rod capable of sliding front and back is connected to the base in a sliding mode, and digital display type measuring rulers are connected to the first sliding blo
