Device and method for testing bonding strength of high-precision interface

The invention discloses a device and a method for testing the bonding strength of a high-precision interface, solves the problems that fiber self-adaptive calibration is unlikely to realize and the testing precision is low in the prior art, and has the beneficial effect that self-adaptive vertical calibration in the fiber drawing direction is realized, so that the testing precision of the bonding strength of the interface is greatly improved. Through the technical scheme, the device comprises an upper clamping device and a lower clamping device, the upper clamping device is clamped to an upper cross beam of an electronic universal testing machine, a cross beam is arranged on the upper surface of the upper clamping device, key grooves are formed in two sides of the upper surface of the upper clamping device, the cross beam is connected with rollers through hinge pins, and the rollers can roll in the key grooves; the middle part of the cross beam is connected with a fiber clamping device through a fastener, and
