[0083] In this embodiment, when machining the side wall of the core sealing plug 101, it is placed on the first positioning column 13 to position it, and then it is locked and fixed by the first fixing nut. The first support column 12 forms a support at the bottom of the core sealing plug 101. The outer diameter of the first support column 12 is relatively small, which does not affect the machining of the side wall of the core sealing plug 101. The core sealing plug 101 after positioning and fixing is coaxial with the first clamping column 11. After the machining equipment clamps and fixes the first clamping column 11, the axis of the core sealing plug 101 is accurately positioned. The machining equipment processes the core sealing plug 101 so that its outer diameter is equal to the design value. The first clamping assembly 1 is easy to install, accurately positioned, and firmly fixed, ensuring the machining quality of the outer wall of the core sealing plug 101.

The positioned and fixed core seal plug 101 is coaxial with the second clamping column 21, and the axis of the core seal plug 101 is accurately positioned after the machining equipment clamps and fixes the second clamping column 21. The machining equipment machines the planar end of the core seal plug 101 to remove most of the excess, and retains a preset reserve for subsequent grinding and polishing.

The third clamping assembly 3 is easy to install, accurately positioned, and firmly fixed, ensuring the processing quality of the arc surface end 1011 of the core seal plug 101.

[0088] The arc surface end 1011 is formed between the grinding and polishing of the plane end, so the depth of the second positioning groove 32 is calculated with the reserve amount of the plane end, that is, the size of the plane end in this embodiment includes the polishing reserve amount.

Then the reference part 45 is placed on the top of the core sealing plug 101, and the fixing bolts are passed through the through hole 46 and the center hole of the core sealing plug 101 in sequence, and are threadedly connected with the fourth screw hole 44, and the fixing bolts are tightened to lock and fix the reference part 45 and the core sealing plug 101. The fixing bolt is only provided with an external thread at the bottom end, and the part above the external thread is rod-shaped and matches the inner diameter of the through hole 46, so as to realize the positioning and installation of the reference part 45. After the installation is completed, the chamfer 1013 is machined with the conical surface 47 as the reference.

[0092] After the chamfer 1013 is machined and formed, the fixing bolts and the reference member 45 are removed, and then the core seal plug 101 is locked and fixed by the third top screw.

[0094] In this embodiment, when machining the planar sealing plug 102, firstly, one end of the part blank is clamped and fixed by the machining equipment, and the other end is machined into a small cylindrical section 1021, and then the small cylindrical section 1021 is embedded in the fourth positioning groove 53, and locked and fixed by the fourth top screw. At this time, the machining equipment clamps and fixes the fifth clamping column 51, and then the large cylindrical section 1022 is machined and formed, ensuring the coaxiality of the large cylindrical section 1022 and the small cylindrical section 1021. The second clamping assembly 2 is easy to install, accurately positioned, and firmly fixed, ensuring the processing quality of the planar sealing plug 102.

At this time, the machining equipment clamps and fixes the sixth clamping column 61, and the planar end of the large cylindrical section 1022 is machined to remove most of the excess, and the preset reserve amount is retained for subsequent grinding and polishing. Then remove the planar sealing plug 102, reposition and clamp the small cylindrical section 1021 upward, and process the planar end of the small cylindrical section 1021. The sixth clamping assembly 6 is easy to install, accurately positioned, and firmly fixed, ensuring the processing quality of the planar sealing plug 102.
