FASTENING TOOL, BOLT SETTING DEVICE AND METHOD OF ASSEMBLING HIGH-PRESSURE COMPRESSOR ROTOR Russian patent published in 2024 - IPC B25B27/16 B25B11/02 B23P19/04 

FIELD: machine building.

SUBSTANCE: group of inventions relates to assembly production and can be used as a fastening tool and corresponding tooling for installation of bolts when assembling rotors of high-pressure compressors. Fastening tool comprises a support part, an upper part, at least part of which is located in the support part, a pushing part having an inclined transfer surface, lever having first and second ends and a hinge part between them, and a transmitting part, at that, the inclined transmitting surface of the pushing part is conjugated along a sliding fit with the transmitting part, which is installed with the possibility of applying a force to the second end of the lever so that it can turn, and the first end of the lever is arranged with the possibility of applying a force to the upper part to ensure its movement outward from the support part when the pushing part moves towards the support part, wherein upper part, pushing part and lever are made with weight, angle of inclination of transmitting surface of pushing part and value of friction between mating guide section of pushing part and guide section of support part, providing support of pushing part in state of self-locking and locking of upper part in upper position after movement of pushing part towards support part.

EFFECT: use of inventions allows simplifying the design of the tool and the process of assembling rotors.
