Method for removing damaged honeycombs of thin-wall annular honeycomb part

Abstract

The invention relates to a method for removing damaged honeycombs of a thin-wall annular honeycomb part. The method includes the following steps that the honeycombs are removed through turning, the damaged honeycombs are removed to the maximum extent, and the number of residual honeycombs is controlled within the smallest range; the residual honeycombs are removed through manual grinding, and a dividing head is used for removing all residual honeycombs of the annular part; a clamp is mounted, the honeycomb turning-removing clamp is placed on a chuck of a machine tool to be clamped, and the clamp is clamped after alignment; the part is mounted, and the part is placed in the honeycomb turning-removing clamp and then pressed through a pressing plate; and the honeycombs are turned, the honeycombs are removed at a low rotating speed in a deep cutting-in mode through a hard alloy tool, and machining is stopped and the part is discharged when a base body is partially exposed from a turned surface. By means of the method, the part is reasonably constrained and pressed, deformation of the part is prevented from further enlarging, the damaged honeycomb removing process is more stable, and machining quality and efficiency are further improved; the method has the characteristics that the process scheme is novel and reasonable, honeycomb grinding-removing efficiency is high, the quality is stable, and part deformation is small.

Description

technical field [0001] The invention relates to a component damage removal technology, in particular to a method for removing honeycomb damage of thin-walled annular honeycomb parts. Background technique [0002] After the honeycomb component is used for a certain period of time, the honeycomb is severely worn, and the damaged honeycomb needs to be removed and replaced with a new honeycomb. Honeycomb removal is usually carried out in two steps. First, most of the honeycomb is removed by turning method, and then all the remaining honeycomb is removed by manual grinding, and then new honeycomb is welded again. [0003] Car processing to remove honeycomb, usually use a three-jaw or four-jaw chuck to clamp the part radially, because the thin-walled annular honeycomb is a weakly rigid part, it deforms greatly in the free state, and the clamping deformation of the part makes the residual after turning There are more honeycombs, which increases the workload of subsequent manual po...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art that the remaining honeycomb components need to be hand-held and the grinding position of the ring parts is constantly adjusted when grinding, which has a certain impact on the grinding quality and grinding efficiency, the technical problem to be solved by the present invention is to provide a
