[0002] At present, a crescent wrench or a cylindrical locking tool is often used to fix and lock the round nut, but the crescent wrench is not suitable for narrow spaces or pre-tightening in the hole. When the cylindrical locking tool is assembled, the round nut is completely covered, which cannot Effectively judge the locking condition of round nuts, and each type of round nut needs to be equipped with a tooling, which requires a large number of tools, heavy weight, and inconvenient use

The invention relates to a round nut locking tool, and belongs to the field of mechanical assembly. The round nut locking tool comprises a plurality of clamping jaw single bodies which are evenly distributed in the circumferential direction. Each clamping jaw single body comprises a connecting part and a fixing part which are connected, and a taper gear shaft is arranged at the end, away from the fixing part, of each connecting part. The tool further comprises a conical fluted disc, the clamping jaw single bodies are connected to the conical fluted disc through taper gear shafts, and the clamping jaw single bodies move in the direction close to or away from the conical fluted disc along with rotation of the conical fluted disc. The round nut locking tool can be used for round nut pre-tightening under the working condition of narrow space or the working condition of round nuts in holes, various round nuts can be installed, and production investment is reduced; the locking condition of the round nut can be observed in the pre-tightening process, so that the non-locking or over-tightening condition is prevented, and the product quality is improved; adn the clamping jaw single bodies can be replaced independently when damaged, and the whole tool does not need to be scrapped, so that the cost is saved.
Description
technical field [0001] The invention belongs to the field of mechanical assembly and relates to a round nut locking tool. Background technique [0002] At present, a crescent wrench or a cylindrical locking tool is often used to fix and lock the round nut, but the crescent wrench is not suitable for narrow spaces or pre-tightening in the hole. When the cylindrical locking tool is assembled, all the round nuts are covered, which cannot Effectively judge the locking condition of round nuts, and each specification of round nuts needs to be equipped with a tooling, which requires a large number of tools, heavy weight, and inconvenient use. Contents of the invention [0003] In view of this, the object of the present invention is to provide a round nut locking tool, which is suitable for more specifications of round nuts, can observe the locking situation of the round nut during the pre-tightening process, improves product quality, and reduces tooling investment. [0004] To a...
