Embodiment Construction
[0021] The embodiment of the present application provides a half-shell processing method with a plurality of spiral grooves distributed on the outer circle, which solves the phenomenon of stretching and twisting of the thin-walled long half-shell in the prior art after cutting, resulting in a certain tension or compression after assembly. power, there are technical problems with greater hidden dangers.
[0022] The technical solution in the embodiment of the present application is to solve the above-mentioned technical problems, and the general idea is as follows:
[0023] A half-shell processing method in which a plurality of spiral grooves are distributed on the outer circle, the method includes: rough machining the outer surface and the inner surface of a steel pipe; cutting the roughly machined steel pipe symmetrically into two pieces along the axis; The two pieces are fixed, and an assembly butt joint hole is processed on the process chuck at both ends of each of the two ...
