description The utility model discloses a measuring device machine system for drilling component stress. The measuring device comprises a measuring tube, a limiting plate is arranged in the measuring tube, the limiting plate extends in the length direction of the measuring tube and is equal to the measuring tube in length, the measuring tube is suitable for deforming outwards when the internal pressure of the measuring tube is increased, and the limiting plate is used for limiting deformation of the measuring tube in the direction where the limiting plate is located. The perimeter of the cross section pattern of the measuring tube before and after deformation is unchanged, and the cross section pattern of the measuring tube before and after deformation is symmetrical about the limiting plate. The measuring system comprises a measuring device, a stress sensor, a stress collector and an oil pump. The first end, the second end and the third end of the stress sensor are connected with a measuring pipe of the measuring device
