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

The anti-machine that quivers of propeller blade surface milling adds fixture
Technical field
The anti-vibration machining fixture used when the present invention relates to a kind of propeller blade fine finishining, particularly a kind of to having the anti-fixture that quivers of the one used when high inclination-angle and complex-curved propeller blade carry out fine finishining.
Background technology
When turnning and milling high inclination-angle and complex-curved propeller blade, because its blade is thin, blade screw angle is large, and in process, propeller blade chatter amplitude is large, and blade-shaped value is not easy to control.The support ring processed on propeller blade cylindrical that the processing method of usual employing stays when being and relying on roughing, carry out support to propeller blade entirety to fix, but it is fixing only to rely on lateral branch pushing out ring to support, cannot overcome propeller blade seriously trembling in fine finishining, make the processing fineness of spoon of blade reach technological requirement.Screw fine finishining of the prior art also has and adopts inclination lathe processing plane, or carries out that multiple operation carries out processing, but it is low to there is working (machining) efficiency, cannot meet the defect of batch production requirements.
Summary of the invention
The anti-machine that quivers that the invention provides the surface milling of a kind of propeller blade adds fixture, solves the anti-technical problem of quivering of propeller blade when fine finishining.
The present invention solves above technical problem by the following technical programs:
A kind of anti-machine that quivers of propeller blade surface milling adds fixture, comprise square base, square base is provided with cylinder shape groove, propeller blade to be processed is connected with overall in propeller blade outer support ring, propeller blade with propeller blade outer support ring is integrally provided in cylinder shape groove, the bottom surface of cylinder shape groove is provided with elastic support unit installing hole, elastic support unit installing hole is arranged on immediately below propeller blade, correcting wedge is movably set with at the bottom of the hole of elastic support unit installing hole, correcting wedge is provided with elastic support unit hydraulic cylinder, the top of the output shaft of elastic support unit hydraulic cylinder is provided with spherical, arc cover body is provided with between the spherical and the bottom surface of propeller blade of the output shaft of elastic support unit hydraulic cylinder.
The outer circumference of cylinder shape groove is evenly equipped with pressing plate, and pressing plate is linked together by bridge screw and square base.
The present invention adopts propeller blade outer support ring and elastic support unit from the way of float support below blade, solve the problem of rigidity deficiency in propeller processing process, make the buffeting of vane amplitude of propeller blade in finishing passes control to minimum, reach the accurately machined technological requirement of blade.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is that the present invention overlooks the structural representation on direction.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail:
A kind of anti-machine that quivers of propeller blade surface milling adds fixture, comprise square base 1, square base 1 is provided with cylinder shape groove 2, propeller blade to be processed is connected with overall in propeller blade outer support ring 5, propeller blade with propeller blade outer support ring 5 is integrally provided in cylinder shape groove 2, the bottom surface of cylinder shape groove 2 is provided with elastic support unit installing hole 8, elastic support unit installing hole 8 is arranged on immediately below propeller blade 6, correcting wedge 12 is movably set with at the bottom of the hole of elastic support unit installing hole 8, correcting wedge 12 is provided with elastic support unit hydraulic cylinder 9, the top of the output shaft 10 of elastic support unit hydraulic cylinder 9 is provided with spherical 7, arc cover body 11 is provided with between the spherical 7 and the bottom surface of propeller blade 6 of the output shaft 10 of elastic support unit hydraulic cylinder 9.
The outer circumference of cylinder shape groove 2 is evenly equipped with pressing plate 3, and pressing plate 3 is linked together by bridge screw 4 and square base 1.
Positioning and clamping process of the present invention is as follows:
Square base 1 is fixed on platen, adjustment correcting wedge 12, make its upper surface vertical with the normal direction line of propeller blade, put in cylinder shape groove 2 by the propeller blade entirety of band propeller blade outer support ring 5, propeller blade outer support ring 5 is pressed in cylinder shape groove 2 by rotary pressure plate 3.Start the hydraulic selector of elastic support unit hydraulic cylinder 9, the output shaft 10 of elastic support unit hydraulic cylinder 9 is moved upward, between the spherical 7 and the bottom surface of propeller blade 6 of the output shaft 10 of elastic support unit hydraulic cylinder 9, arc cover body 11 is set, when the bottom surface of the output shaft 10 of elastic support unit hydraulic cylinder 9, arc cover body 11 and propeller blade 6 fully contacts, and contact force is when reaching setting value (being generally 5-15 newton), close the hydraulic selector of elastic support unit hydraulic cylinder 9, then carry out the surperficial turnning and milling of propeller blade 6.
