Abstract
The invention relates to a flexible tool for processing a plane of easy-deformed materials. The flexible tool comprises a long threaded rod 1, a flexible positioning semisphere 2, a positioning base 3, a base 4, two positioning blocks 5 and a nut 6. Flexible clamping is achieved by means of flexible supporting points, it is maintained that the tool compresses a part in a free state to the greatest extent when the tool applies clamping force, product dimensions of machined products and surface quality of parts are ensured, and parts do not deform after being unloaded.
Description
Technical field
The invention belongs to aeronautical engineering field, relate to a kind of flexible frock processing the processing of yielding material plane.
Background technology
For mutability material parts, tradition is rigidity clamping, in frock, common clamping is at least tri-point support, and be rigid support, and step up processing at part upper surface plus-pressure, because the distortion of roughing standard plane applies pressure compaction at part upper surface, part upper surface is caused to produce distortion.And part unclamp or fastening nut time screw thread stock follow rotation, waste time and energy when causing installing or removing part; Be that face contacts when screw thread stock coordinates with hole in piece part, if part occurs that namely trickle beat can cause alignment pin partial loop variation, occur deviations.
Summary of the invention
The technical problem to be solved in the present invention: for the difficulty of processing problem of yielding material plane.
Technical scheme of the present invention: a kind of flexible frock processing yielding material plane, it is characterized in that: comprise screw thread stock 1, flexible location hemisphere 2, positioning seat 3, base 4, two locating pieces 5, nut 6 and pressing plate, wherein, screw thread stock 1 is cylindrical structure, be fixed on positioning seat 3, flexible location hemisphere 2 is the sphere structure of 2/3rds, and through hole is offered on the working face 7 that cross section is circular, flexible location hemisphere 2 is inserted in from screw thread stock 1, contact with the hemispherical depression that positioning seat 3 is arranged and coordinate, and matched in clearance between screw thread stock 1, ensure that the working face 7 of flexible location hemisphere 2 can flexiblely swing, working face 7 and part strong point are fitted, form a flexible support point 8, positioning seat 3 connects and is fixed on base 4, screw thread stock 1 is dolioform with the part of feature contacts, ensure and part non-face contact, two locating pieces 5 are fixed on base 4, support part forms two other rigid support point 9, pressing plate is used for part and frock pressing.
Described flexibility location hemisphere 2 be composite construction, and internal diameter also has a flexible location hemisphere and is inserted in from screw thread stock 1, strengthens this flexibility and locates the working face of hemisphere and part strong point and fit and strengthen the flexibility of this mechanism.
Beneficial effect of the present invention: through changing flexible clamping into, maintains the workpiece pressing of part in free state when product applies chucking power to greatest extent, does not have deformation effect after ensure that Product processing after the surface quality of product size, part and part unloading.

Detailed description of the invention
Below in conjunction with Figure of description, installation of the present invention and working method are described.
The vital part in helicopter lift system at the upper and lower clamping plate part of the aluminum matrix composite of the lift system of helicopter, it is connected to helicopter and rotor blades thus makes helicopter have the power of flight, its dimensional accuracy and distortion directly affect the flight safety of whole helicopter, and its upper and lower cleat assembly plays key effect at the lift system of helicopter.
Distortion plane machining flexible clamping device of the present invention is successfully applied to the process of the upper and lower clamping plate in above-mentioned upper and lower cleat assembly, in order to overcome in original upper and lower clamping plate process due to pressing plate compress, part product distortion and the accessory size that causes cannot ensure, the defect of the index such as part deformation after the not up to standard and processing of machined surface roughness, improve the qualification rate of the upper and lower clamping plate of aluminum matrix composite, first the plane processed for Set and Positioning is manufactured, as shown in Figure 3, the plane at flexible support point 8 and rigid support point 9 place; Make the screw thread stock 1 of band waist-drum-shaped profile, screw thread stock 1 with waist-drum-shaped profile is matched in clearance with the locating hole on the flexible part strong point 8, see Fig. 1, the bottom of the screw thread stock 1 with waist-drum-shaped profile is square positioning screw cap head, penetrate in the locating hole on device 3 and the flexible part strong point 8 by the bottom of device, and ensure that the screw thread stock 1 of waist-drum-shaped profile is located mutually with the angle of device 3 and 4, see Fig. 1.Flexibility location hemisphere 2 is put into positioning seat 3 device, the screw thread stock 1 of band waist-drum-shaped profile is made to penetrate the endoporus of flexible location hemisphere 2, screw thread stock 1 and the flexibility flexibility of retainer belt waist-drum-shaped profile locates the suitable gap of the endoporus of hemisphere 2, and the flexible location spherical outside surface of hemisphere 2 and the Internal Spherical Surface of positioning seat 3 device complete that fit also can relative sliding simultaneously.
By adjustment part, the screw thread stock 1 of waist-drum-shaped profile is penetrated in the first hole, location on the flexible part strong point 8, fitting with the plane of the flexible part strong point 8 above of flexible location hemisphere 2, tightens the nut 6 on the screw thread stock 1 of waist-drum-shaped profile, compressing component; Flexible location hemisphere 2 also can ensure fitting completely with the plane of flexible support point 8 of flexible location hemisphere 2 above with part deformation, and the distortion produced from eliminating part stress deformation compresses, and ensure that part does not have processing parts under moment of torsion stress again.
The use of described distortion plane machining flexible clamping device, overcome and cause part deformation, distortion, step up power clamping and the defect of the index such as part above and below nonparallelism and gauge in the part distorting stress that produces and cutting process, improve product percent of pass.
