120mm, long 150mm, material is No. 45 steel, adopts and is bolted to inside frame 1; Left iron core 2 with right iron core 13 are provided with the identical left magnet exciting coil 3 of model and right magnet exciting coil 12, coil adopts the copper wire of wire diameter 0.56mm, the number of turn is 2000 circles, to be energized the magnetic field produced perpendicular to left wedge shape guiding chamber wall 4 and right wedge shape guiding chamber wall 11 to left magnet exciting coil 3 and right magnet exciting coil 12 by D.C. regulated power supply 21.
The first positioner 8 in a left side of workpiece and the right side just positioner 18 adopt No. 45 steel to make, and wherein the left just mode that positioner 8 is with bolts is arranged on and is parallel on the chamber wall 16 of magnetic direction; And right just positioner 18 can be slided up and down by dovetail groove 17, be fixed together by bolt and the chamber wall 16 being parallel to magnetic direction after determining the accurate mounting plane of blade 7.The U-shaped structure upper end of the first positioner 18 of left just positioner 8 and the right side all has a bolt can move up and down for clamping and releasing blade 7.When blade 7 is installed, its one end is pressed on the rafter plate of blade 7 by terminal bolt on left just positioner 8, the other end determines the best position of blade 7 bottom surface geomery by adjusting the right just position of positioner 18 on dovetail groove 17, by bolt by the right side just positioner 18 be fixed on and be parallel on the chamber wall 16 of magnetic direction, rotate the false boss of left just positioner 8 and first positioner 18 upper end, right side bolt presses blade 7, play the accurate initial position determining blade 7; Diameter is
4mm, material are that the support bar 20 of aluminium alloy is arranged on container bottom 14 central authorities, wherein support bar 20 top is provided with displacement transducer 19, it contacts with blade 7, is subjected to displacement for measuring clamping process and process Leaf due to the effect of clamping force and cutting force; After each parts relative position fixes, the magnetic flow liquid 15 that mass fraction is 70% is poured in magnetic flow liquid container, by D.C. regulated power supply 21, left magnet exciting coil 3 and right magnet exciting coil 12 are energized the magnetic field produced perpendicular to left wedge shape guiding chamber wall 4 and right wedge shape guiding chamber wall 11, magnetic flow liquid 15 is solidified, produces shear stress.
Record blade 7 by displacement transducer 19 in clamping and magnetic flow liquid solidification process, produce amount of displacement adjustment current parameters, control magnetic flow liquid state of cure, ensure the initial alignment precision of blade 7.Magnetic flow liquid 15 not to add under magnetic field conditions matching blade 7 shape freely, after D.C. regulated power supply 21 is energized generation magnetic field to left magnet exciting coil 3 and right magnet exciting coil 12, in container, magnetic flow liquid 15 is rapidly from Newtonian fluid state to Stuart Bingham class solid state, the liquid of matching part also forms class solid state, plays support part, improves the target of the rigidity of part.Consider that magnetic flow liquid 15 only produces support force and can not meet blade 7 and process needs under magnetic fields, therefore adopt bolt rotation forces to move down perpendicular to the left wedge block 6 of magnetic direction and right wedge block 10, reduce vessel interior volume and extruding is produced to magnetic flow liquid 15, the magnetic flow liquid 15 in container after solidification is impelled to form stronger magnetic-particle chain structure, the shear strength of further raising magnetic flow liquid, larger support force is produced to blade 7, play better supporting role, the rigidity of effective raising thin wall vane 7 to be processed, thus effectively improve machining accuracy and crudy.
At the end of to be processed, magnetic field is removed left magnet exciting coil 3 and right magnet exciting coil 12 power-off, now magnetorheological fluid materials returns to fluid state, loses shear ability, thus can take out blade 7 easily.
The superiority of this flexible support fixture is mainly reflected in following aspect: as changed the complex thin-wall blade parts of processing different model, only need change the size of magnetic flow liquid container, increase coil turn and ensure magnetic field intensity, and do not need to change whole chucking appliance system.Such as adopt length, width and height to be of a size of the large molten bath of 100 × 200 × 200mm, need the replacing number of turn to be about the coil of 5000 circles.
