Abstract

The invention discloses an assembling tool for an impeller cover assembly and belongs to the field of water jet propulsion tools. The assembling tool for the impeller cover assembly comprises a support positioning assembly, a lining pre-support positioning assembly and a pressure-applying assembly. The support positioning assembly comprises a support positioning plate and a first fastener, wherein the support positioning plate is used for bearing one end of an impeller cover shell, and the first fastener is configured to fix one end of the impeller cover shell to the support positioning plate. The lining pre-support positioning assembly comprises a pull rope hanging frame and at least two lining pre-support positioning units. The pressure-applying assembly comprises a stress plate, a pressing plate and a second fastener. By the adoption of the assembling tool for the impeller cover assembly, the assembling success rate is increased, only the positions of an intra-cover insulating lining and an intra-cover steel lining need to be finely adjusted later, the assembling workload is reduced, and the assembling period is shortened.

Description

technical field [0001] The invention relates to the field of tooling for water jet propulsion devices, in particular to an assembly tooling for an impeller cover assembly. Background technique [0002] The water jet propulsion device is a kind of power device for ships and other water transport vehicles. It mainly generates jet water by jetting water from the stern at high speed, and uses the reaction force of jet water to realize the propulsion of the ship, and can change the jet of water jet The direction realizes operations such as forward sailing, reverse sailing, lateral movement, oblique movement or in-situ steering of the ship. [0003] The impeller cover assembly is one of the main components of the water jet propulsion device. The impeller cover assembly includes the impeller cover, the inner insulating bushing and the inner steel bushing. The inner insulating bushing is installed in the impeller casing, and the inner steel lining The sleeve is installed in the ins...
