Vacuum adsorption test device of adapter

The invention relates to a vacuum adsorption test device of an adapter in the technical field of test devices. The vacuum adsorption test device of the adapter comprises a main body frame, a control cabinet, a simulation cylinder, a pair of support cylinders, a sliding frame, a driving part, a front induction group and a rear induction group; the control cabinet monitors a test state; the material of the simulation cylinder is the same as the material of a missile launcher; the pair of support cylinders are respectively connected to the front and rear ends of the simulation cylinder coaxially; the sliding frame presses the adapter on the inner arc surface of the simulation cylinder while testing; the sliding frame is installed on the main body frame horizontally and movably; the driving part drives the sliding frame to horizontally move; the front induction group is installed on the main body frame, and corresponds to the front end position of the simulation cylinder; and the rear induction group is installed
