Abstract

A shaft tube inner hole repairing device comprises a positioning installation support, a boring machine and a to-be-repaired shaft tube, and a flange coaxial with the to-be-repaired shaft tube is fixedly arranged at the front end of the to-be-repaired shaft tube; the positioning installation support comprises an installation transverse plate and an installation vertical plate, the rear end of the installation transverse plate is perpendicularly connected with the front face of the installation vertical plate, the back face of the installation vertical plate is attached to the front end face of the flange, the installation vertical plate is fixedly connected with the flange through installation bolts, and the boring machine is fixedly arranged on the installation transverse plate. A shaft tube inner hole repairing method comprises the following steps that a positioning installation support is installed; a boring machine is mounted on the positioning mounting bracket; adjusting the position of a boring machine; and installing a cutter and repairing the inner hole of the shaft tube. According to the design, the inner hole of the shaft tube can be repaired on site in a narrow space, the repair period is shortened, and the repair precision is high.

Description

technical field [0001] The invention relates to the technical field of overhaul, in particular to a repairing device and a repairing method for an inner hole of a shaft tube, and is particularly suitable for overhauling an inner hole of a shaft tube. Background technique [0002] During the repair, dismantling and inspection of the shipyard, the inner hole of the shaft tube is often strained during operation, which affects the performance of the inner hole of the shaft tube and the components installed in it. Severe axial strain is prone to occur, resulting in a decline in the sealing performance of the piston and the flexibility of the piston. When the inner hole of the shaft tube is strained, the traditional repair scheme needs to decompose the shaft section, and then remove the shaft section to be repaired out of the cabin and transfer it to the machining equipment for repair. [0003] However, the traditional repair scheme has great defects: the traditional repair schem...
