Technical Field

[0001] The utility model relates to the technical field of impeller processing, in particular to a clamp for processing an integrally cast high-speed three-dimensional flow impeller. Background Art

[0002] Impeller refers to the wheel disc with moving blades, which is a component of the impulse turbine rotor, and can also refer to the general term for the wheel disc and the rotating blades installed on it. Impellers can be classified according to their shape and opening and closing conditions. In the production and processing of impellers, fixtures are very common and indispensable tools.

It is necessary to design clamps of different sizes according to the product size; and the lack of a positioning mechanism can easily cause the problem of inaccurate impeller positioning, affecting product quality. For example, a Chinese patent discloses an impeller processing fixture, and its application number is: CN202221434791.5, which includes: the technical field of control device, a chuck, a mounting block, an elastic member and a connecting rod, and three clamps are arranged on the chuck The three clamps can be synchronously contracted inward or expanded outward on the chuck. The clamp is connected to a mounting block through a mounting assembly. The contact surface between the mounting block and the impeller is larger than the contact surface between the clamp and the impeller. A mounting block adapted to the circumference of the impeller is provided at the clamping position of the clamp, so that the contact area between the mounting block and the circumference of the impeller is much larger than the contact area between the clamp and the circumference of the impeller. Although it can fix the impeller during processing, its device lacks a positioning mechanism, which can easily cause the problem of inaccurate impeller positioning, and it cannot clamp impellers of different specifications, so its applicability is relatively limited.
