The invention discloses a self-adaptive expansion positioning mechanism for assembling and positioning an airplane barrel section, which comprises a positioning pin, the lower part of the positioning pin is inserted into a shell, the positioning pin forms a ratchet mechanism through a nut, a supporting plate, a lifting handle, a shifting piece and a shifting groove, and the upper part of the positioning pin forms an expansion positioning structure through a mandrel, a conical column, an expansion sleeve, a nut, a positioning handle and a top cover. The ratchet mechanism ascends and descends through mechanical transmission, the expansion positioning mechanism above is driven to reach the theoretical position, and expansion positioning operation is conducted by operating the positioning handle. The positioning mechanism has the advantages that operation is convenient and fast, rapid positioning and separation of the positioning mechanism are achieved, the product production quality is improved, the rejection rate is reduced, the production takt efficiency is improved, and powerful support is provided for rapid production of aircraft products.

    本发明公开了一种用于飞机桶段装配定位的自适应膨胀定位机构,包括定位销,定位销下部通过安插在外壳内,定位销通过丝母、托板、升降手柄、拨片、拨槽形成棘轮机构,定位销上部通过芯轴、锥柱、膨胀套、螺母、定位手柄、顶盖形成膨胀定位结构,棘轮机构通过机械传动实现升降,带动上方膨胀定位机构到达理论位置,并通过操作定位手柄进行膨胀定位操作。本发明的特点是:操作便捷,实现定位机构的快速定位与脱离,提升了产品生产质量,降低了废品率,提高了生产节拍效率,为飞机产品的快速生产提供了有力支持。
