The invention belongs to the field of airplane structure strength testing, and particularly relates to a wing box section testing device. The device comprises a bottom beam (1) and a loading box section (3), a supporting stand column (8) is arranged on the bottom beam (1), and an actuating cylinder (2) is arranged on the outer side of the supporting stand column (8); the loading box section (3) comprises box section bodies (17) arranged at the two ends of the test piece (18), the two box section bodies (17) are erected on two supporting stand columns (8) respectively, a first convex hinge (61) is fixed to the lower end of the box section body (17) on one side, a concave hinge (4) is fixed to the corresponding supporting stand column (8), a force bearing base plate (9) is fixed to the lower end of the box section body (17) on the other side, and a second convex hinge (61) is fixed to the lower end of the force bearing base plate (9). Second convex hinges (62) are fixed to the corresponding supporting stand columns (8), and double lugs (14) are further fixed to the box section body (17) so as to be hinged to the loading end of the actuator cylinder (2). According to the invention, the strength test of the wing box section in a pure bending moment loading form is realized.
