The invention provides a rubber jacket hydraulic automatic combining device and method of a
butterfly valve assembly machine. The rubber jacket hydraulic automatic combining device is convenient and safe to use, and pressure of a main unit can be adjusted in time according to
butterfly valve rubber jackets of different types and specifications; working efficiency and quality are greatly improved, the rate of finished products reaches above 99%, and good
economic benefits are achieved; due to the fact that
automatic control is adopted for the rubber jacket hydraulic automatic combining device and method, a man-
machine security coefficient is high, a great amount of time and a great deal of
energy resources are saved, maintenance cost caused by abrasion is reduced, the performance of the entire
machine is improved, the service life of the entire machine is prolonged, and production cost is lowered. The rubber jacket hydraulic automatic combining device of the
butterfly valve assembly machine comprises a butterfly valve
assembly worktable, an
infrared ray induction safety device, a tool base, an
assembly machine stand column, a pressure head tool, a pressure regulating valve device, an upper hydraulic oil cylinder supporting frame, a pressure gauge, an upper
hydraulic cylinder device, an PLC control box device, control buttons, an electrical cabinet device, a butterfly valve tool, a locking nut mechanism, a downward pressing lead screw assembly, a motor device, a
piston rod device and the like.
