Background Art

[0002] When disassembling and assembling the cutter tooth group of the existing titanium sponge splitting machine, usually the external accessories are removed first, the main components are disassembled, and then it is transported to the maintenance workshop by a special rotating device for more professional disassembly. The whole titanium sponge splitting machine is disassembled into various small components or parts. Then, the parts and components are respectively cleaned, repaired, and parts are replaced, and then assembled into components and transported back to the workshop for assembly. During the disassembly, repair, and assembly of the existing titanium sponge splitting machine, due to the limitation of tools for disassembly in the workshop, the degree of disassembly is relatively low, so large transport equipment must be used for transportation, significantly increasing the maintenance cost. At the same time, even when disassembling beside the machine in the workshop, some local methods and local tools are usually used for manual disassembly. For example, when disassembling and assembling the cutter tooth group: using a fixed wrench to disassemble and assemble nuts, using a chain block to adjust the shear frame of the cutter tooth group, and pulling the cutter tooth group to a place with a large grab loader to grab and install the bearing are time-consuming and laborious.

The combined sleeve consists of three parts (a socket for the large nut, a socket for the pneumatic air gun, and a thick-walled steel pipe connecting them in the middle). The length of the thick-walled pipe is determined according to the disassembly and assembly requirements. First, the socket for the large nut and the socket for the pneumatic air gun are processed respectively according to the large nut specification and the rotating head of the pneumatic air gun. The socket is processed from a 45# steel bar.
