Description

Polishing and grinding device for refining inner ring and outer ring of casting nozzle ring
Technical Field

A jet engine is a reaction engine that generates thrust by jet. Jet engines in a broad sense include rocket engines and air jet engines. The fuel and the oxidant of the rocket engine are carried by the aircraft, and the rocket engine comprises a solid fuel rocket engine and a liquid fuel rocket engine and is characterized by being capable of working outside an atmospheric layer; air jet engines do not take in oxidant but rather draw air from the atmosphere as an oxidant, including ramjet engines, pulse engines, turbojet engines, turbofan engines, and the like.
The turbine jet engine mainly comprises two types, namely a radial turbine and an axial turbine, wherein the radial turbine mainly comprises an air inlet volute, a nozzle ring, a working wheel, an air outlet channel and the like; when the turbine is in operation, exhaust gas flows in from the outer edge of the rotor of the working wheel through the air inlet volute, and flows out from the center of the turbine axially after acting.
The nozzle ring is a plurality of tapered channels which are uniformly arranged in the circumferential direction and are formed by blades with certain inclination angles, when the airflow flows through the nozzle ring, partial pressure energy is converted into kinetic energy, the air is accelerated, the pressure and the temperature are reduced, and the nozzle ring has strong directivity and is convenient for uniformly and orderly flowing into the working wheel of the turbine.
It is clear that the nozzle ring is the main component of the work done by the turbine, and the manufacturing accuracy of the nozzle ring directly affects the efficiency of the work done by the turbine. In practical production, the nozzle ring is usually cast, but the cast nozzle ring inevitably has defects of low manufacturing precision, high surface roughness and the like, and the service life of the turbojet engine is affected if the nozzle ring is directly put into use without finishing.
The finishing processing of the casting nozzle ring mainly comprises two parts, namely polishing of the inner ring of the nozzle ring and polishing of the outer ring of the nozzle ring, but due to the particularity of the appearance of the nozzle ring, when the inner ring and the outer ring of the nozzle ring are polished and finished by adopting a traditional polishing device or polishing mode, the following problems often occur:
1. the polishing function is single, and the omnibearing fine finishing of the inner ring and the outer ring of the nozzle ring is difficult to realize. Specifically, different parts of the nozzle ring need to be polished in different manners to achieve targeted polishing, but the existing polishing device is single in function, can only achieve specific finishing polishing, and lacks polishing optimization for the nozzle ring.
2. And the clamping is inconvenient. Specifically, the inner ring and the outer ring of the nozzle ring are both machining surfaces, so that the problem that a machining mechanism hinders interference in the polishing and grinding process is very easy to occur in the machining and clamping process.
3. The polishing and grinding continuity is poor, and the inner ring and the outer ring are required to be disassembled and reassembled for many times in the polishing and grinding process, so that the processing efficiency is affected.
In summary, it is clear that the prior art has inconvenience and defects in practical use, so that improvement is needed.
