The invention belongs to the field of aviation assembly, and particularly relates to a fixing device for a shear strength sample and a usage method. The fixing device for the shear strength sample comprises a cover plate, a base, a limiter, a handle, a pin shaft, a compression spring, a flat plate, a screw, an ejector part and a cylindrical pin. According to the fixing device designed according tothe size of the sample, the position of the sample and the length of the bonding surface are restrained through the accurately calculated size of the groove, Meanwhile, the spring is arranged on theouter side of the clamping device to transmit externally applied pressure to ensure curing pressure, so that the problem that the shear strength is unqualified after the sample is heated and cured issolved. The fixing device for the shear strength sample and the usage method are used for guaranteeing the position accuracy, the bonding surface length and the curing pressure of the sample during heating curing, and therefore it is guaranteed that the shear strength of the cured sample meets the requirement.

    本发明属于航空装配领域,具体涉及一种用于剪切强度试样的固定装置和使用方法。其中,所述的用于剪切强度试样的固定装置包括盖板、底座、限位器、手柄、销轴、压缩弹簧、平板、螺钉、顶件和圆柱销。按照试样尺寸设计的固定装置,通过精确计算后的凹槽尺寸来约束试样的位置及粘接面长度,同时在夹紧装置外侧设置弹簧来传递外部施加的压力以保证固化压力,从而解决试样加温固化后剪切强度不合格的问题。本发明提供的用于剪切强度试样的固定装置和使用方法用于保证试样加温固化时的位置准确度、粘接面长度以及固化压力,从而保证试样固化后的剪切强度符合要求。
