Universal assembly tool of threaded connection structure

The utility model discloses a universal assembly tool of a threaded connection structure. The universal assembly tool comprises a supporting ring and a check block. More than three threaded through holes which are uniformly distributed in the circumferential direction are formed in the supporting ring, and the axis of each threaded through hole is consistent with the radial direction of the supporting ring; the inner ring face of the supporting ring is connected with a check block corresponding to each threaded through hole. Wherein a threaded blind hole is formed in the check block, and the supporting ring is connected with the check block through a bolt; the assembling tool overcomes the defect that the assembling tool is special during thread assembling of the small solid rocket engine, has the advantages of being convenient and easy to operate, low in production cost, high in assembling efficiency and the like, and can achieve batch assembling of threaded connection. 本实用新型公开了一种螺纹连接结构的通用型装配工装，包括：支撑环和挡块；所述支
