Nozzle ring machining clamp for turbocharger

Abstract

The invention relates to the technical field of nozzle ring machining, in particular to a nozzle ring machining clamp for a turbocharger. The nozzle ring machining clamp for the turbocharger comprises a loading rack, an operation carrying surface arranged on the loading rack, and a plurality of clamp mechanisms mounted on the operation carrying surface; each clamp mechanism is provided with a transmission module, an inner positioning assembly and an outer positioning assembly, wherein the inner positioning assemblies and the outer positioning assemblies are installed on the transmission modules; the inner positioning assembly comprises a built-in rotating disc and an inner extrusion piece installed on the outer edge of the built-in rotating disc; the inner extrusion piece extrudes and is attached to the inner ring surface of the nozzle ring; the outer positioning assembly comprises a displacement seat, an outer clamp assembly and an outer limiting assembly, wherein the outer clamp assembly and the outer limiting assembly are installed on the displacement seat; the displacement seat is installed on the track of the transmission module; the inner side of the outer clamp assembly is attached to the outer ring surface of the nozzle ring; and the two ends of the outer limiting assembly are attached to the outer ring surface of the nozzle ring in a rolling type tangential mode. According to the design, multi-point annular support is formed on the inner ring surface of the nozzle ring; and the outer clamp assembly is adopted on the outer ring surface of the nozzle ring to clamp the two sides of the nozzle ring.

Description

technical field [0001] The invention relates to the technical field of nozzle ring processing, in particular to a nozzle ring processing fixture for a turbocharger. Background technique [0002] The nozzle ring is a very important part of the turbocharger. Its function is to control the amount of exhaust gas entering the box in the volute. When the engine speed increases, the amount of exhaust gas reaches a certain level, and gradually prevents the exhaust gas from entering the "bypass." ”; so that part of the exhaust gas directly enters the exhaust pipe through the pressure relief valve hole without pushing the turbine, so that the turbocharger can be kept in normal working condition. [0003] The nozzle ring is a stainless steel product. The clamping operation of the nozzle ring in the prior art generally includes an upper mold and a lower mold installed together. The upper mold and the lower mold are hollow structures inside, so that the nozzle ring is clamped sideways. ...

AI Technical Summary

Problems solved by technology

[0003] The nozzle ring is a stainless steel product. The clamping operation of the nozzle ring in the prior art generally includes an upper mold and a lower mold installed together. The inside of the upper mold and the lower mold is a hollow structure, so that the nozzle ring is clamped sideways. Fixed operation; however, there are certain defects in the existing technology. The single contradictory clamping of the nozzle ring from the side wing is not only insufficient in stability, but also easily causes the problem of nozzle ring deformation; if it is clamped on the annular surface of the nozzle ring, It will affect the processing operation of the nozzle ring
