Kaplan turbine blade machining equipment based on ship

Abstract

The invention relates to the field of ships, in particular to Kaplan turbine blade machining equipment based on a ship. The technical problem to be solved by the invention is to provide the Kaplan turbine blade machining equipment based on the ship. According to the technical scheme, the Kaplan turbine blade machining equipment based on the ship comprises a bottom plate assembly, a cleaning unit, a polishing unit and the like; the bottom plate assembly is fixedly connected with the cleaning unit; and the bottom plate assembly is fixedly connected with the polishing unit. After a blade is conveyed to a designated position, impurities left on the upper face and the lower face of the blade are removed, then a center supporting column of the blade is polished, then the outer contour of the blade is polished, burrs and deckle edges in the blade are removed, meanwhile, the two sides of the blade are polished by adapting to the height of the blade, the size precision of the blades is improved, the weight error of each blade is reduced, and meanwhile the unbalanced weight of a balance test is reduced.

Description

technical field [0001] The invention relates to the field of ships, in particular to a ship-based paddle turbine blade processing equipment. Background technique [0002] At present, for the blades of the axial-flow propeller turbines, since the blades have a spatial curve structure, in the prior art, the method of rough machining the flange end face and outer circle of the journal is usually used, and then the blades are manually polished. In this process, the blades are easily rubbed against the packaging materials during the transportation process, and impurities are easily left in the blades, and because the blades are curved structures, artificial Grinding is difficult to control and the grinding intensity is always consistent, resulting in poor blade dimensional accuracy and a large error in the weight of each blade, resulting in more unbalanced weight in the static balance test after wheel assembly, and subsequent processing is more difficult. [0003] In summary, it...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the present situation, for the blades of the tubular and axial flow propeller turbines, since the blades have a space curve structure, in the prior art, the end face and the outer circle of the flange of the journal are usually roughly machined, and then the blades are manually polished. During the process, the blades are easily rubbed against the packaging materials during the transportation process, and impurities are easily left in the blades, and because the blades have a curved structure, However, manual grinding is difficult to control and keep the grinding intensity consistent, which leads to poor dimensional accuracy of the blades, large weight error of each blade, resulting in more unbalanced weight in the static balance test after wheel assembly, and more difficult follow-up processing. The technical problem to be solved by the invention is to provide a ship-based paddle turbine blade processing equipment
