Profiling grinding repairing device for end surface of arresting gear of aero-engine

Abstract

The invention relates to a profiling grinding repairing device for the end surface of an arresting gear of an aero-engine. The profiling grinding repairing device comprises a base, a swinging mechanism, a clamping mechanism and a grinding mechanism; the swinging mechanism is fixedly mounted on one side above the base; the clamping mechanism is fixedly mounted on the other side above the base; the grinding mechanism is mounted on the swinging mechanism; the arresting gear is fixed to the clamping mechanism; an output end of the grinding mechanism grinds the arc end surface of the arresting gear; the output end of the grinding mechanism can perform reciprocating arc swinging relative to the arc end surface under the swinging action of the swinging mechanism. The profiling grinding repairing device has the advantages that the grinding trajectory is amplified by utilizing a profiling principle; profiling grinding is performed on the end surface of the arresting gear by adopting the profiling swinging mechanism of the arresting gear; the profiling grinding repairing device is low in manufacturing cost and easy to operate; batch production is easy to realize; through a transmission mechanism, the labour intensity of an operator is reduced; the operation is simple; the grinding efficiency is high; the grinding consistency is high; the precision is high.

Description

technical field [0001] The invention relates to the field of aero-engine maintenance, in particular to a profiling grinding and repairing device for the end face of an aero-engine stopper. Background technique [0002] During the disassembly and overhaul of a certain type of aero-engine, it was found that the stopper figure 1 As shown, there is a through hole 2 in the middle of the stopper 1, and it is installed on the aero-engine through the through hole 2. The two ends of the stopper 1 are provided with arc end faces 3, and the arc end faces 3 are working surfaces. The wear and tear of the arc end face 3 in the middle part leads to scrapping. The amount of scrapping of this part is large, and frequent replacement of new products will greatly increase the production cost. At present, the commonly used repair method is to use argon tungsten arc welding on the end face to increase the thickness, but the grinding of the front end face of argon arc welding and manual grinding ...

[0002] During the disassembly and overhaul of a certain type of aero-engine, it was found that the stopper figure 1 As shown, there is a through hole 2 in the middle of the stopper 1, and it is installed on the aero-engine through the through hole 2. The two ends of the stopper 1 are provided with arc end faces 3, and the arc end faces 3 are working surfaces. The arc end face 3 is worn out and scrapped, and the scrap volume of this part is large, and frequent replacement of new products will greatly increase the production cost

At present, the commonly used repair method is to use argon tungsten arc welding on the end face to increase the thickness, but the grinding of the front end face of argon arc welding and manual grinding are generally used for post-welding repairs. The production efficiency is low, time-consuming and labor-intensive, which will seriously affect Production progress, while manual grinding will vary according to the level of workers, resulting in uneven grinding quality and affecting accuracy requirements
