Rapid pasting device for bidirectional optical fiber strain measurement

According to the rapid pasting device for bidirectional optical fiber strain measurement provided by the utility model, the axial and annular pasting of the optical fiber strain sensor on the housing of a solid rocket engine is satisfied through the two pads which are perpendicular to each other, and the molding direction of the optical fiber strain sensor is guided through the grooves on the positioning pads at the two ends of the pads. The bidirectional test included angle precision is ensured; according to the utility model, shaft collar bidirectional manual pasting work of an optical fiber strain sensor in a solid rocket engine structural strength strain test process is replaced, and the problem of bidirectional strain measurement of the optical fiber strain sensor applied to a solid rocket engine static strength test is solved; compared with manual pasting, the optical fiber strain sensor can be pasted in a bidirectional strain mode at a time, it is guaranteed that bidirectional pre-tightening force is a
