Rotor cutting processing method using running balance indicating machine and special device thereof

Abstract

The invention discloses a method for cutting and processing a rotor by means of a dynamic balancing machine, which consists of the procedures of regulating turning rolls of two supporting points on the dynamic balancing machine to be isometry; placing the rotor on the turning rolls of two supporting points on the dynamic balancing machine; propping the two ends of the rotor by using a cabane at the two ends of the dynamic balancing machine, and compressing the rotor by using a compressing frame of the dynamic balancing machine, with an astragal of the dynamic balancing machine as a device fordriving the rotor to rotate; fastening a lathe bed of the dynamic balancing machine with a fixed frame for placing a processing lathe; and cutting and processing the rotor by the processing lathe. The method for cutting and processing the rotor by means of the dynamic balancing machine has the advantages of convenient processing, easy operation, and being capable of saving the working procedure of dismantling an impeller.

Description

Technical field: [0001] The invention relates to a cutting processing method and a special device for a rotor. Background technique: [0002] With the prosperity of the international and domestic marine transportation industry, the maintenance tasks of ships are becoming more and more arduous, and the requirements for ship repair technology are also getting higher and higher; The key is the maintenance of the turbine rotor. The difficulties in maintenance are: large volume, heavy weight, and easy deformation of the gas seal ring. The gas seal, shaft head, and exhaust gas blade must be processed by a large lathe. Now let’s talk about the diesel engine turbine rotor gas seal. .Spindle head cutting and blade grinding. [0003] The marine (10,000-ton) diesel engine turbine rotor is composed of wind guide impeller, compressed air impeller and exhaust gas impeller and other components. Its working principle is: the exhaust gas discharged from the diesel engine during operation e...

Problems solved by technology

When heating, the temperature should not be too high. If it is too high, the fastening hole of the compressor impeller will expand, and the compressor impeller will be scrapped. If the temperature is low, the compressor impeller cannot be disassembled. The temperature should be controlled at about 120 degrees (measured with a special thermometer)

Some rotor impellers are difficult to disassemble after working in a long-term high-temperature and harsh environment, and need multiple times of thermal expansion and contraction before disassembly (although some rotor impellers are disassembled, they can no longer be restored to their original state, and they will eventually be scrapped)

The rotor turning during processing, the disassembly and assembly of the impeller and the insulation wall are very cumbersome.
