Downhole permanent magnet generator rotor magnetic cylinder assembling tool

Abstract

The invention relates to the technical field of generator part assembling tool, and particularly relates to a downhole permanent magnet generator rotor magnetic cylinder assembling tool. A bottom plate is fixed on the surface of the frame. The cylinder body of a magnetic cylinder mounting cylinder is provided with a strip-shaped slot hole. One end of a non-magnetic slide shaft is provided with a pressure pad. The pressure pad extends into the inner cavity of the magnetic cylinder mounting cylinder after passing through the strip-shaped slot hole. A stop ring is arranged on the shaft body of the non-magnetic slide shaft. A spring is pressed between the stop ring and a fixing sleeve. A pull shaft mechanism is arranged on the frame. One end of the pull shaft mechanism is fixedly connected with the other end of the non-magnetic slide shaft. One end of a magnetic cylinder angle positioning device is fixed on a vertical plate. When the tool is used, collision and fragmentation of the permanent magnets due to the fact that the permanent magnets cannot be fixed can be avoided by the assembling tool, the magnet scrapping rate can be reduced, and the permanent magnets of the same permanent magnet mounting groove can be mounted without waiting for solidifying of the adhesive, thereby greatly improving the mounting efficiency of the magnets, reducing the labor cost and reducing the labor intensity.

Description

technical field [0001] The invention relates to the technical field of assembly tooling for generator components, in particular to an assembly tooling for a rotor magnetic cylinder of an underground permanent magnet generator. Background technique [0002] Measuring-while-drilling logging system and rotary steerable system play a vital role in the current oil drilling field. During the working process of the instrument, it is necessary to supply power to the downhole electronic measurement module of the measurement-while-drilling logging system and the steering control module of the rotary steerable system. Since there is no cable conductor downhole returning to the ground, the power supply must be located downhole. There are two types of downhole power supplies, lithium battery packs and downhole turbine generators. Lithium battery packs have many shortcomings such as poor high temperature resistance (<125°C), short service life (<200h), low output power, and poor s...

AI Technical Summary

Problems solved by technology

[0006] The existing operation process has the following disadvantages: 1. When bonding two permanent magnets in the same permanent magnet groove, the two permanent magnets are easy to collide and break due to mutual repulsion, and the permanent magnet scrap rate is high; 2. Due to the need to wait All the bonding work can be completed after 24 hours of adhesive curing time, and the work efficiency is low; 3. The bonding of the permanent magnet and the assembly of the magnetic cylinder are two independent processes, both of which need to be manually operated, which wastes labor costs
