Description
Technical field
The utility model relates to aero-engine leaf dish processing technique field, especially relates to a kind of positioning fixture that is used for the digital control processing of closed type integrated leaf dish.
Background technology
At present, the fan of aero-engine, compressor generally adopt blisk version.Compare with the wheel disc assembly structure with traditional blade, blisk has saved tenon, tongue-and-groove and locking device, has avoided the tenon windage loss; Simultaneously, reduce number of spare parts in a large number, alleviate construction weight.The development trend of integrated impeller blade is that shape becomes increasingly complex, wall thickness is more and more thinner.Utilization thin-walled, ultra-thin blade technology, can solve the compressor air velocity and rise to problems such as the caused blade inlet edge shock wave of supersonic speed, blade tip flow separation from subsonic speed, thereby increase substantially compressor gas flow and single-stage pressure ratio, integrally-built aerodynamic arrangement of aero-engine and service efficiency are greatly improved.At blisk class labyrinth part, the technology difficulty of utilizing means such as hot investment casting or precision forging to produce is very big.In this case, can satisfy the high quality parts that modern designs requires, just need to adopt Machining Technology for Cutting in order to produce.
Closed type integrated leaf dish passage is a closed area, and blade is long, bending is big, and adjacent blades is covered mutually, and the passage opening character is poor, must adopt five coordinate processing modes respectively from leading edge and the feed of exhaust limit, and the control difficulty is bigger; Blisk belongs to typical weak rigid thin wall's class part, existing anchor clamps are adding man-hour, owing to add the effect of the power of holding, be easy to cause the generation of flutter in the bulk deformation of part and the process, influenced stability, surface quality of workpieces and the precision of process.
Summary of the invention
Clamp easy deformation in order to overcome the prior art blade, the deficiency that the location is unstable, the utility model provides a kind of closed type integrated leaf dish digital control processing positioning fixture, by adopting the structure that fixes to clamp of two ends pretension, efficiently solves the problems of the prior art.
The technical scheme that its technical problem that solves the utility model adopts is: comprise base plate, pressing plate and mandrel; Base plate is provided with the fixed installation hole, and base plate is fixed on the platen by the fixed installation hole; The cooperation of mandrel lower end is installed on the base plate, and mandrel and base plate are to install with the centre of gyration, i.e. the home position of the corresponding base plate in the center of circle of mandrel lower end; Outer wheel hub near closed type integrated leaf dish on the base plate is provided with positioning key and pressing plate, the positioning key number is 2N, N is any positive integer, and positioning key is symmetricly set on the outer wheel hub outside, and the outer wheel hub outside of the closed type integrated leaf dish corresponding with positioning key is provided with the angle positioning spline; The pressing plate number is 2M, M is any positive integer, and the pressing plate outer end is placed on base plate top by cushion block, and the inner correspondence of pressing plate is placed on the inboard, outer wheel hub edge of closed type integrated leaf dish, pressing plate connects base plate by screw nut, and realizes the clamping of workpiece and unclamp by rotary nut; The groove that also is provided with any amount on the base plate is as the draining chip area.
The external diameter of described mandrel equals the centre bore internal diameter of closed type integrated leaf dish.
The beneficial effects of the utility model are: described closed type integrated leaf dish digital control processing positioning fixture utilizes the centre bore location of leaf dish, the angle positioning spline of leaf dish is designed at leaf Pan Wailunguchu, and cooperate with positioning key to install and realize the location, axially adopting a plurality of pressing plates to be evenly distributed on leaf dish mode all around compresses the leaf dish, this active force vertical transmission can not cause the bulk deformation of part owing to thrust on clamp base.It is simple in structure, and is easy to use.
Below in conjunction with drawings and Examples the utility model is further specified.
