Full-automatic testing tool for turbocharger

Abstract

The invention discloses a full-automatic testing tool for a turbocharger. The tool comprises a bottom plate, a volute sealing part and a pressure shell sealing part, the volute sealing part comprisesa first volute sealing mechanism and a second volute sealing mechanism; the volute second sealing mechanism is connected with the bottom plate, the pressure shell sealing part is arranged above the volute sealing part, the pressure shell sealing part comprises a pressure shell first sealing mechanism and a pressure shell second sealing mechanism, the pressure shell second sealing mechanism is connected with the first leakage instrument channel, and the volute second sealing mechanism is connected with the second leakage instrument channel. After the structure is adopted, the volute is positioned and sealed by the volute sealing part, and the gas leakage amount of the volute end can be obtained by detecting the second leakage instrument channel connected with the second volute sealing mechanism; the pressure shell sealing part positions and clamps the pressure shell and seals the pressure shell, the gas leakage amount of the pressure end can be measured by detecting the first leakage instrument channel connected with the second sealing mechanism of the pressure shell, and the turbocharger leakage test is completed.

Description

technical field [0001] The invention relates to the technical field of turbochargers, in particular to a fully automatic testing tool for turbochargers. Background technique [0002] Turbocharger products are widely used in automobile engines as the core components of the engine. The operating conditions are long-term under ultra-high speed, high temperature and high pressure, and accompanied by ultra-frequency vibration of the engine. Device products put forward more stringent assembly quality requirements. During the assembly process, the impeller of the core assembly, the turbine, etc., and the scratches on the surface of the turbine shaft will affect the supercharging efficiency of the rotor. Seriously, the rotor will directly scrape the shell and the shaft will be broken. At the same time, the product strength and The sealing effect between parts will also affect the supercharging efficiency, and serious high-temperature air leakage may even affect the safety of the ca...

AI Technical Summary

Problems solved by technology

During the assembly process, the impeller of the core assembly, the turbine, etc., and the scratches on the surface of the turbine shaft will affect the supercharging efficiency of the rotor. Seriously, the rotor will directly scrape the shell and the shaft will be broken. At the same time, the product strength and The sealing effect between parts will also affect the supercharging efficiency, and serious high-temperature air leakage may even affect the safety of the car. Therefore, strengthening the leak test and the anti-slight sticking test of the rotor system before the assembly is completed is to ensure the turbocharger. It is an important step for compressor products to work safely; however, the current assembly relies on the dedication and quality awareness of employees, and there is no leak test for products when they go off the assembly line. The preventability and detection of defective products are far from enough
