The invention belongs to the technical field of airplane strength tests, and particularly relates to a clamping piece type loading lever. The device comprises a lever main body (4), a resultant force point bolt (12), a secondary lever bolt (9) and a secondary bushing (2), wherein the lever body (4) comprises two clamping pieces, the clamping pieces are connected through a resultant force point bolt (12), a round hole (1) is formed in the first end of each clamping piece, a long-strip-shaped hole (7) is formed in the second end of each clamping piece, the first ends of the two clamping pieces are connected through a secondary lever bolt (9) penetrating through the round holes (1) and a secondary lining (2), and the second ends of the two clamping pieces are connected through a long-strip-shaped hole (7) penetrating through the long-strip-shaped hole (7). And the second end parts of the two clamping pieces are connected through another secondary lever bolt (14) and another secondary bushing (8) which penetrate through the strip-shaped hole (7). According to the invention, the top level lever is adaptive to the deformation of the secondary level and the test piece, the loading system is ensured not to limit the deformation of the test piece, and the loading precision of the lever system is improved.

    本申请属于飞机强度试验技术领域,特别涉及一种夹片式加载杠杆。该装置包括杠杆主体(4)、合力点螺栓(12)、次级杠杆螺栓(9)及次级衬套(2);其中,杠杆主体(4)包括两个夹片,夹片中间通过合力点螺栓(12)进行连接,每个所述夹片的第一个端部设置有圆孔(1),第二个端部设置有长条孔(7),两个夹片的第一个端部通过贯穿在圆孔(1)内的次级杠杆螺栓(9)及次级衬套(2)相连接,两个夹片的第二个端部通过贯穿在长条孔(7)内的另一个次级杠杆螺栓(14)及另一个次级衬套(8)相连接。本申请实现了顶级杠杆对次级杠杆及试验件变形的自适应,保证加载系统不限制试验件变形,增加了杠杆系统的加载精度。
