Nozzle ring processing fixture for turbocharger

Abstract

The invention relates to the technical field of nozzle ring processing, in particular to a nozzle ring processing fixture for a turbocharger, including a loading frame, a working surface arranged on the loading frame, and several clamping mechanisms installed on the working surface; the fixture The mechanism is equipped with a transmission module, an inner positioning component and an outer positioning component installed on the transmission module; the inner positioning component includes a built-in turntable, and an inner extrusion part installed on the outer edge of the built-in turntable; the inner extrusion part extrudes and Attached to the inner ring surface of the nozzle ring; the outer positioning assembly includes a displacement seat, an outer clamp assembly installed on the displacement seat and an outer limit assembly. The displacement seat is installed on the track of the transmission module, and the inner side of the outer clamp assembly is fitted On the outer ring surface of the nozzle ring, the two ends of the outer limit component are rolling and tangentially attached to the outer ring surface of the nozzle ring. The design of this application forms a multi-point annular support for the inner ring surface of the nozzle ring; and the outer ring surface uses an outer clamp assembly to form clamping on both 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
