Abstract

The invention provides a positioning tool and repairing device for shaft neck repairing of a large shaft part. The positioning tool comprises a power mechanism and a slewing mechanism clamped on the large shaft part, the slewing mechanism comprises two clamping parts which are axially arranged in a spaced mode, the two clamping parts are each provided with a central hole, the two central holes are coaxially formed and used for allowing the large shaft part to be arranged in a penetrating mode, each clamping part is provided with a positioning assembly which is directionally connected with the large shaft part and connected with the power mechanism through a transmission assembly, and the two clamping parts synchronously rotate around the large shaft part under driving of the power mechanism. Accordingly, shaft neck repairing of the large shaft part is achieved by adopting the machining modes of slewing mechanism rotating and large shaft part fixing, and the positioning tool is simple, portable and convenient to adjust.

Description

technical field [0001] The invention relates to a damage repairing technology for shaft parts, in particular to a positioning tool and repair equipment for repairing journals of large shaft parts. Background technique [0002] With the development of industry, the size of large shaft parts (such as steam turbine and generator rotors, marine crankshafts, etc.) is getting larger and better, and the materials are getting better and better, so the requirements for the journal part as its support are also increasing. High, specifically in the following aspects: high-precision shape tolerances (straightness, roundness, cylindricity, concentricity or outer circle runout, full runout), high-precision dimensional tolerances, high-demand surface roughness ( Generally Ra0.2~Ra0.8). [0003] As the support of the slewing system, the journal is prone to wear, roughening, marks, etc., causing system instability and seriously affecting operation safety. Such large shaft parts are key com...
