Abstract

The invention discloses a labyrinth ring part coating removal protection clamp, a labyrinth ring part comprises a base body ring and a labyrinth ring which are both annular and are connected in the axial direction, sealing labyrinth teeth on the outer ring face of the labyrinth ring are coated with a spraying layer, and the protection clamp comprises a clamp body, an upper cover body and an upper pressing assembly; the clamp body is vertically arranged, the lower end of the clamp body is used for being connected with coating removing equipment, and the opposite upper end of the clamp body is used for supporting and positioning the labyrinth ring piece. The upper cover bodies are oppositely connected to the upper end of the clamp body at intervals so as to be matched with the clamp body to cover and protect a base body ring of the labyrinth ring piece supported and positioned on the clamp body. The upper pressing assembly is connected with the clamp body and used for downwards pressing and fixing the labyrinth ring extending out of the upper cover body to the clamp body. The labyrinth ring part coating removal protection clamp is simple in structure, the labyrinth ring piece is easy and convenient to install, position, protect and the like, and the base body ring is good in protection effect and easy to disassemble.

Description

technical field [0001] The invention relates to the technical field of coating removal on the surface of sealed grate teeth, in particular to a protective jig for removing the coating of a grate tooth ring. In addition, the present invention also relates to a repairing process for the surface coating of the grate ring by using the protective jig for removing the coating of the grate ring. Background technique [0002] The turbine rotor part of a certain type of engine adopts the grate tooth + honeycomb sealing structure for gas sealing, and the baffle plate with the grate tooth structure is installed at the front and rear of each stage of the rotor. With the form of dynamic gas sealing. When the engine is working, the grate tooth is inserted into the honeycomb and rubs against the honeycomb. In order to prevent the wear of the grate tooth tip after long-term operation and ensure the sealing effect, a wear-resistant nickel-aluminum / aluminum oxide coating needs to be sprayed ...
