Description

Technical Field

[0001] The present invention belongs to the technical field of milling equipment processing, and in particular relates to a sealing surface milling device and a sealing surface processing technology of a sealing workpiece. Background Art

[0002] Sealing surface milling equipment is a special machine tool used to process the sealing surfaces of valves, flanges, pipes and other sealing connection components. It can ensure the flatness, smoothness and dimensional accuracy of the sealing surface to meet the sealing requirements of high pressure, high temperature, corrosion resistance and other working conditions. When dealing with on-site sealing surfaces of large equipment (such as large flanges), portable sealing surface milling machines are usually used for repair. During the transportation and storage of large flanges, oil and solid particles will adhere to the sealing surfaces. The milling cutters will come into contact with oil and solid particles during processing, which will reduce the milling efficiency and the service life of the milling cutters. Some flanges will be impacted during transportation and storage, causing the sealing surfaces to deform, resulting in concave or convex areas. The deformed areas need to be inspected so that the milling work can be adjusted according to the deformation conditions when milling the sealing surfaces, thereby ensuring the sealing effect of the sealing surface after milling.

When the lifting detection rod moves upward, the liquid in a cavity in the liquid marking box is sprayed out from the liquid marking box. When the lifting detection rod moves downward, the liquid in another cavity in the liquid marking box is sprayed out from the liquid marking box, and the sprayed liquid falls on the deformation area of ​​the flange sealing surface; the deformation of the flange sealing surface is detected before milling, and the milling work is adjusted according to the deformation of the flange sealing surface to improve the sealing effect of the flange sealing surface after milling.

The vertical moving block 202 moves and drives the rotating mounting plate 301 to move, so that the bottom end of the lifting detection rod 401 contacts the flange sealing surface, and the rotating mounting column 102 rotates and drives the lifting detection rod 401 to move. When the lifting detection rod 401 passes through the concave and convex area on the flange sealing surface caused by deformation, the lifting detection rod 401 moves vertically. When the lifting detection rod 401 moves upward, the liquid in one cavity in the liquid marking box 402 is sprayed out from the liquid marking box 402. When the lifting detection rod 401 moves downward, the liquid in another cavity in the liquid marking box 402 is sprayed out from the liquid marking box 402. The sprayed liquid falls on the deformation area of ​​the flange sealing surface, and the liquid color is different.
