Run-out detection machine

The utility model discloses a run-out detection machine comprising a frame, a bearing rotary device, a run-out detection device and an output device. The bearing rotary device comprises a fixing shaft, a rotating wheel, a first elastic piece, a second elastic piece, an intermediate connecting sleeve, a bearing collar, a driving assembly, a first fixing member, a second fixing member, a third fixing member and a fourth fixing member. The fixing shaft is installed on a mounting platform, the rotating wheel, the first elastic piece, the intermediate connecting sleeve, the second elastic piece and the bearing collar sleeve the fixing shaft and can rotate relative to the fixing shaft. The driving assembly drives the rotating wheel to rotate. One end of the first fixing member is connected with the rotating wheel, and other end of the first fixing member is connected with the first elastic piece; one end of the second fixing member is connected with the first elastic piece, and the other end of the second fixing member is connected with one end of the intermediate connecting sleeve; one end of the third fixing member is connected with the other end of the intermediate connecting sleeve, and the other end of the third fixing member is connected with the second elastic piece; and one end of the fourth fixing member is connected with the second elastic piece, and the other end of the fourth fixing member is connected with the bearing collar. An object to be detected is carried on the bearing collar. The run-out detection machine is simple in structure and low in cost and can rotate flexibly.
