Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to a detection device for processing a turbine shell. Background Art

[0002] The turbine housing, as the core component of the turbocharger system, is usually made of high-strength, high-temperature resistant alloy materials through precision casting and processing to ensure that it can withstand high-speed rotation and high-temperature and high-pressure working environments. The quality and performance of the turbine housing directly affect the efficiency, stability and service life of the turbocharger.

[0003] During the processing of the turbine shell, quality inspection can timely discover the size deviation, shape defects, insufficient material performance and other problems of the turbine shell, ensuring that the accuracy and performance of the turbine shell meet the design requirements. This not only helps to improve the overall performance of the turbocharger, but also effectively avoids failures and safety hazards caused by quality problems of the turbine shell, which is of great significance for ensuring the stable operation of the turbocharger system. Traditional turbine shell inspection equipment can often only focus on a single inspection indicator. For example, the airtightness inspection equipment can only detect the sealing performance of the turbine shell, while the size inspection equipment focuses on the geometric size measurement of the turbine shell. This kind of inspection method with clear division of labor but single function requires frequent equipment replacement throughout the inspection process, which is not only time-consuming and labor-intensive, but also increases the risk of error; and the existing size measurement device is easily affected by interference factors such as vibration of external equipment during actual use, which may cause deviations in the measurement data, affect the accuracy of the measurement, and have an adverse effect on the processing quality assessment of the turbine shell.
