Testing device for swing assembly

The invention discloses a test device for a swing assembly, relates to the technical field of rocket engine testing, and aims to solve the problem that multiple groups of assembly error working conditions cannot be verified during testing. The test device comprises a frame body with a cross beam and a stand column; the driving mechanism is provided with a driving end and a fixed end, and the fixed end is rotationally connected with the cross beam and drives in the vertical direction; the rotating axis of the gimbal seat is perpendicular to the driving direction of the driving mechanism; the other end of the first connecting piece is rotationally connected with the driving end of the driving mechanism; two ends of the connecting pipe are respectively connected with the first connecting piece and one end of the swinging hose; the sensor detects the driving load of the driving mechanism; the controller controls the driving mechanism to move according to detection information. The driving mechanism is started, by
