Abstract

The invention belongs to the technical field of machine manufacturing, and particularly relates to an annular spherical bearing locating pin disassembly tool. The annular spherical bearing locating pin disassembly tool comprises a supporting device, locating locking devices, a travel limiting instruction adjusting screw, a guide rod, a striking heavy hammer, striking heavy hammer handles and a replaceable threaded connector. A sliding guide groove is formed in the upper surface of the supporting device; one end of the guide rod is in thread connection with the replaceable threaded connector, and the other end of the guide rod is sequentially in thread connection with the travel limiting instruction adjusting screw and the locating locking devices; the other end of the travel limiting instruction adjusting screw is sequentially screwed to the locating locking devices by threads; the striking heavy hammer is of a hollow cylindrical structure overall; and the striking heavy hammer penetrates through the end, with the replaceable threaded connector, of the guide rod, and is arranged in the sliding guide groove.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a tool for removing positioning pins of annular spherical tiles. Background technique [0002] At present, in the K-1000-60 / 3000 steam turbine, the low-pressure steam valves of the steam turbine are respectively equipped with 8 sets of 1426545CB butterfly valves. The butterfly valves are jointly supported by the drive end support and the free end support. Copper bushings are necessary spare parts for overhaul, and two copper bushings need to be replaced for each valve. [0003] In the process of replacing the copper bushing, it is necessary to disassemble the drive end and the free end support. The disassembly process will involve a relatively complicated and very important maintenance process, that is, how to correctly and quickly remove the positioning between the tile pillow and the spherical tile pin. According to the requirements of the mainten...
