It is provided with elastic support unit mounting hole (8) to include on the bottom surface of cylindrical recess (2), elastic support unit mounting hole (8) sets up under the propeller blades (6), hole bottom activity at elastic support unit mounting hole (8) is provided with wedge cushion (12), be provided with elastic support unit pneumatic cylinder (9) on wedge cushion (12), the top of output shaft (10) of elastic support unit pneumatic cylinder (9) is provided with spherical face (7), be provided with between the lower bottom surface of the spherical face (7) and the propeller blades (6) of output shaft (10) of elastic support unit pneumatic cylinder (9) arc cover physically (11). The utility model discloses make the propeller blades arrive the minimum at the buffeting of vane amplitude control of finish machining in -process, reached the accurately machined technological requirement of blade.
Description
Technical field
The anti-vibration machining fixture used when the present invention relates to a kind of water screw blade precision work, in particular to a kind of to the anti-fixture that quivers of one having a high spud angle and use when complex-curved water screw blade carries out precision work.
Background technology
When car milling high spud angle and complex-curved water screw blade, owing to its blade is thin, blade screw angle is big, and in the course of processing, water screw blade chatter amplitude is big, and blade-shaped value is not easy control. Usually the working method adopted relies on the support ring processed on water screw blade cylindrical stayed during roughing, carry out water screw blade entirety supporting and fix, but it is fixing only to rely on outside support ring to support, cannot overcome water screw blade seriously trembling in precision work, make the processing smooth finish of spoon of blade cannot reach processing requirement. Water screw precision work of the prior art also has and adopts machine tooling plane, or carries out what multiple operation carried 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 present invention provides a kind of water screw blade surface milling adds fixture, solves the anti-technical problem quivered of water screw blade when precision work.
The present invention solves above technical problem by the following technical programs:
The anti-machine that quivers of a kind of water screw blade surface milling adds fixture, comprise square base, square base is provided with cylinder shape groove, propeller blade outer support ring is connected with water screw blade to be processed overall, water screw 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 open holes, elastic support unit open holes is the underface being arranged on water screw blade, it is movably set with quoin at the bottom of the hole of elastic support unit open holes, quoin is provided with elastic support unit hydro-cylinder, the top of the output shaft of elastic support unit hydro-cylinder is provided with spherical, it is provided with arc cover body between the spherical of output shaft and the bottom surface of water screw blade of elastic support unit hydro-cylinder.
Being evenly equipped with pressing plate in the outer circumference of cylinder shape groove, pressing plate is linked together by bridge screw and square base.
The present invention adopt propeller blade outer support ring and elastic support unit float below blade support way, solve the problem of rigidity deficiency in propeller processing process, make the blade chatter amplitude of propeller blade in precision work process control to minimum, reach the processing requirement of blade precision work.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention;
Fig. 2 is that the present invention is at the structural representation overlooking on direction.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail:
The anti-machine that quivers of a kind of water screw blade surface milling adds fixture, comprise square base 1, square base 1 is provided with cylinder shape groove 2, propeller blade outer support ring 5 is connected with water screw blade to be processed overall, water screw 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 open holes 8, elastic support unit open holes 8 is the underface being arranged on water screw blade 6, quoin 12 it is movably set with at the bottom of the hole of elastic support unit open holes 8, quoin 12 is provided with elastic support unit hydro-cylinder 9, the top of the output shaft 10 of elastic support unit hydro-cylinder 9 is provided with spherical 7, it is provided with arc cover body 11 between the spherical 7 of output shaft 10 and the bottom surface of water screw blade 6 of elastic support unit hydro-cylinder 9.
Being evenly equipped with pressing plate 3 in the outer circumference of cylinder shape groove 2, pressing plate 3 is linked together by bridge screw 4 and square base 1.
The positioning and clamping process of the present invention is as follows:
Square base 1 is fixed on platen, adjustment quoin 12, make its upper surface vertical with the normal direction line of water screw blade, putting in cylinder shape groove 2 by the water screw 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 hydro valve of elastic support unit hydro-cylinder 9, the output shaft 10 of elastic support unit hydro-cylinder 9 is upwards moved, between the spherical 7 of output shaft 10 and the bottom surface of water screw blade 6 of elastic support unit hydro-cylinder 9, arc cover body 11 is set, when the bottom surface of the output shaft 10 of elastic support unit hydro-cylinder 9, arc cover body 11 and water screw blade 6 fully contacts, and contact force is when reaching set(ting)value (being generally 5-15 newton), close the hydro valve of elastic support unit hydro-cylinder 9, then carry out the surperficial car milling of water screw blade 6.
