A high-pressure static seal groove surface defect grinding and repairing machine

Abstract

The invention provides a high-pressure static sealing groove surface defect grinding repair machine. The high-pressure static sealing groove surface defect grinding repair machine comprises a pneumatic motor and a frame; the frame comprises a frame cross beam and a frame support; a pneumatic motor fixing support is arranged on the frame cross beam; the top of the pneumatic motor is connected with an intake pipe; an intake regulating valve is arranged on the intake pipe; a transmission shaft is arranged at the lower end of the pneumatic motor; the transmission shaft is connected with the pneumatic motor by use of a coupling; a transmission assembly is arranged under the coupling; a hold-down rotating disc and a grinding ring support are fixed at the tail end of the transmission shaft by use of locking nuts; a special grinding ring is mounted on the grinding ring support. The high-pressure static sealing groove surface defect grinding repair machine is used for solving the problem of sealing groove surface repair; the machine is simple in design and reasonable in structure; a workpiece to be repaired is placed under the special grinding ring, and the sealing groove surface can be quickly repaired under the action of the pneumatic motor; the working intensity is reduced and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tool repair, in particular to a high-pressure static seal groove surface defect grinding repair machine. Background technique [0002] In the flange production process, the flange sealing groove surface of some large-diameter high-pressure equipment and pipelines is prone to static sealing defects. At present, the main way to deal with these static seal defects is to carry out manual grinding repair. The specific method is to repair by manpower non-stop turning the cast iron grinding ring weighing more than 40 kg. The grinding ring needs to replace the abrasive every other working time. Frequent disassembly of the grinding ring is required. This method of manually repairing static sealing defects has high labor intensity and low production efficiency, and there are certain safety hazards at the same time. Contents of the invention [0003] The present invention provides a high-pressure static sealing ...
