Abstract

The invention discloses a vibration prevention machining clamp for milling the surfaces of propeller blades. The vibration prevention machining clamp achieves the purpose that vibration is prevented in the finish machining process of the propeller blades. The vibration prevention machining clamp is characterized in that elastic supporting unit mounting holes (8) are formed in the bottom face of a cylindrical groove (2) and formed under the propeller blades (6), and wedge-shaped cushion blocks (12) are movably arranged at the hole bottoms of the elastic supporting unit mounting holes (8); and elastic supporting unit hydraulic cylinders (9) are arranged on the wedge-shaped cushion blocks (12), the top ends of output shafts (10) of the elastic supporting unit hydraulic cylinders (9) are provided with spherical faces (7), and arc-shaped cover bodies (11) are arranged between the spherical faces (7) of the output shafts (10) of the elastic supporting unit hydraulic cylinders (9) and the lower bottom faces of the propeller blades (6). By the adoption of the vibration prevention machining clamp, the blade vibration amplitude of the propeller blades in the finishing machining process is controlled to the minimum, and the finishing machining process requirements of the blades is achieved.

Description

technical field [0001] The invention relates to an anti-vibration machine processing jig used in the finishing process of propeller blades, in particular to an anti-vibration jig used in finishing the propeller blades with large inclination angle and complex curved surface. Background technique [0002] When turning and milling propeller blades with large inclination angles and complex curved surfaces, due to the thinness of the blades and the large helix angle of the blades, the vibration of the propeller blades is large during processing, and the blade shape value is not easy to control. The usual processing method is to rely on the support ring machined on the outer circle of the propeller blade left during rough machining to support and fix the propeller blade as a whole. Severe trembling during processing makes the processing finish of the curved surface of the blade unable to meet the process requirements. The propeller finishing in the prior art also adopts inclined ...
