Embodiment
After the detailed description of embodiment of the disclosure is read in conjunction with the following drawings, it better understood when the present invention's
Features described above and advantage.In the accompanying drawings, each component is not necessarily drawn to scale, and with similar correlation properties or feature
Component may have same or like reference.
Fig. 1 shows conic tube and the assembling of straight barrel circular arc flange and the preferred embodiment of machining manufacture of the present invention
Flow.As shown in figure 1, details are as follows for each step in the method for the present embodiment.
Step S1：Trunnion axis structural drawings flange figure according to Fig. 2, straight barrel and conic tube is segmented, according to each
Fragment size, rolls straight barrel and conic tube respectively.
Cylinder size is checked in this step, it is unqualified, it is corrected.Fig. 2 shows horizontal axle construction shell flange,
Specifically show the assembling structure of straight barrel flange 1 and conic tube flange 2.
Step S2：Car will be found on flange joint cylinder, end binding face is machined out, to ensure that end face is vertical.
Step S3：Cylinder orthogonal sets on horizontal moulding bed to pre-splicing, detect and adjust the misalignment of docking port, two connecting cylinders
The linearity and axiality of body.
The group pair of conic tube flange is as shown in figure 3, Fig. 3 shows flange joint machining 3.
Whether inspection group is to pre-splicing qualified, if unqualified, cylinder is carried out operating on correction immediately, and machine cylinder again
It is again pre-splicing behind body end portion.
