Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of supercharger production, specifically to a numerical control milling machine for supercharger component machining. BACKGROUND

[0002] The supercharger blade is a core component, and its machining precision directly relates to the overall performance of the supercharger. The blade structure mainly consists of a blade body, a tenon root and a rim plate: the blade body gives the blade a unique aerodynamic shape; the tenon root is responsible for stable connection with other components; and the rim plate is a transition area between the blade body and the tenon root. With the continuous improvement of the performance standard of the supercharger, the design of the blade is increasingly precise, and the manufacturing specification is also increasingly strict. In order to optimize the aerodynamic efficiency, the supercharger blade is thin and long, the blade body presents a complex free-form surface shape, and the bending and twisting degree is significant; at the same time, in order to reduce the weight and enhance the durability, high-strength materials such as titanium alloy are often used, which are difficult to process. These characteristics pose a high challenge to the clamping process before blade machining.

[0003] When the tenon root is used to position and clamp the blade, due to the differences in the process table position and size of different blades, if the auxiliary clamping support device is installed strictly according to the theoretical position, unnecessary clamping stress will often be applied to the blade tip by the process table. Machining the blade body in this state, even if the quality seems good during the machining process, once the clamping device is loosened, the blade will deform due to stress release, thereby introducing clamping errors, which seriously affects the yield and final performance of the blade.
