Description

Technical Field

[0001] This utility model relates to the field of turbine housing technology, specifically a turbine housing riveting assembly tooling for a turbocharger. Background Technology

[0002] A turbine is an engine that generates power by the impact of fluid on the rotation of an impeller. When machining a turbine casing, tooling is required. Using clamping tooling, the turbine casing is clamped and held in a stable state, which facilitates the machining of the turbine casing.

[0003] Existing turbine housing riveting fixtures may lack an effective adjustment mechanism to accommodate the clamping requirements of turbine housings of different sizes. For small turbine housings, they may not provide a sufficient clamping gap, leading to insecure clamping or excessive compression of the turbine housing. For large turbine housings, they may not achieve a sufficiently large span to stably fix the turbine housing, resulting in displacement during processing, severely affecting machining accuracy and increasing scrap rate. Furthermore, when the turbine housing has a complex shape and different parts require riveting at specific angles, the inability to precisely rotate to the appropriate angle limits the riveting to easily accessible locations, resulting in substandard riveting quality in critical areas and impacting the overall performance and reliability of the turbocharger. Therefore, we introduce a turbine housing riveting fixture for turbochargers. Utility Model Content

[0039] Specifically, in use, the air cylinder B10 on the side plate 9 is started, and the output end is elongated. Since the output end of the air cylinder B10 is connected to one side of the positioning plate A11, a pushing force is directly applied to the positioning plate A11, so that the slide A8 at the bottom of the positioning plate A11 moves in the direction of the slide rail 2. When the positioning plate A11 moves, the toothed plate B16 connected to one side thereof also moves.
