Description
(1) technical field
The present invention relates to a kind of die curve polishing tool that is used with lathe,, be applicable to the occasion that realizes the polishing technology automation in particular for die curve automation polishing with unit head.
(2) background technology
Mold cavity surface 65% is a curved surface, and wherein 40% is free form surface.The service object of die industry comprises automobile panel, motorcycle plastic covering spare, household electrical appliance such as television set, washing machine, air-conditioning, telecommunication products such as mobile phone shell, car light shell.The mould of these industries, especially mould of plastics all have high requirements to the mold cavity surface roughness, and part need reach the minute surface requirement, and therefore, curved surface polishing becomes requisite process procedure, and according to statistics, polishing accounts for the 30%-50% of entire die manufacturing time.
The free form surface mold polish is mainly finished by manual operations, and polishing efficiency is low, labour intensity is big, the health that is harmful to health, be difficult to guarantee to polish the stability of shape surface accuracy, polishing poor quality simultaneously.State inner mold industry roughness to the polishing technology of Ra0.05 μ m still can, but the Ultraprecise polished technology that reaches Ra0.025 μ m level is still located the stage of fumbling, a large amount of ultraprecise injection molds still need import.Also the shortcoming of Cun Zaiing is: 1, polishing tool and free form surface contact area are little, and polishing efficiency is lower; 2, the dispersion abrasive particle distribution between polishing tool and the free form surface is wayward; 3, the whole field method of burnishing surface is unstable and inhomogeneous to polishing force, can not obtain high polishing quality; 4, traditional flexible polishing instrument generally is to utilize spring or flexible polishing material to obtain instrument to contact with flexibility between the burnishing surface, but its flexible degree all cannot onlinely be controlled; 5, can not accurately control the local polishing removal amount, it is cumbersome to carry out the accurate correction of local shape face.
(3) summary of the invention
The tool heads flexibility that prior art die curve polishing tool exists is not capable of on-line, the polishing contact area is little, curved surface polishing efficient is low in order to overcome, curvature of curved surface is changed shortcomings such as adaptability is bad, the invention provides a kind of tool heads flexible capable of on-line, the polishing contact area is big, curved surface polishing efficient height, to the good magnetic rheology type flexible polisher with air bag of curvature of curved surface variation adaptability.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of magnetic rheology type flexible polisher with air bag, described polishing tool comprise that an air bag, described air bag front end have polishing cloth as working face, and described air bag front end also has an interlayer, is filled with magnetic flow liquid in the described interlayer; Described air bag is installed in the retainer; Described retainer is installed on the turning cylinder, and the front end of described turning cylinder stretches in the described air bag, and described turning cylinder front end is equipped with electromagnet; Described turning cylinder socket one sleeve pipe, described sleeve pipe and described turning cylinder are tightly connected, and have outer air source inlet, overflow valve on the described sleeve pipe; Have gas channel on the turning cylinder in the sleeve pipe, described gas channel is communicated with described air bag.
Further, in the described sleeve pipe mechanically-sealing apparatus is installed, described mechanically-sealing apparatus comprises spring, seal.
Further again, described retainer comprises rubbing head outer cover, rubbing head inner cover, and rubbing head outer cover and rubbing head inner cover are affixed by screw thread, and the rubbing head outer cover is affixed by screw thread and turning cylinder, and polishing cloth is connected with the rubbing head outer cover by jump ring.
The basic principle of magnetic rheology type flexible polisher with air bag is: the power transmission shaft of magnetic rheology type flexible polisher with air bag can be clamped in any lathe (as parallel robot, machining center, milling machine, drilling machine) obtains to drive power on the unit head, rotate at a high speed thereby drive air bag; By can regulating the flexibility of air bag, thereby make rubbing head form the flexible polishing working face to the control of air pressure of input air bag; The flexible polishing working face can be easily forms the large tracts of land even contact with the free form surface of polished workpiece; Because magnetic flow liquid can change its viscosity by near the effect in magnetic field, solid-state until being changed to from liquid state, therefore can be by being installed in the formed electromagnetic field in electromagnet energising back of turning cylinder front end, change the character of the magnetic flow liquid in the air bag front end interlayer, make balloon surface have profiling and memory function, the process that realizes balloon surface profiling and memory function is: balloon surface contacts with polished curved surface under the control of the air pressure of air bag, if this moment is the electromagnet no power, then the magnetic flow liquid in the air bag interlayer is complete liquid state, balloon surface is profiling with polished surface and contacts, pass to suitable electric current to electromagnet this moment, then make magnetic flow liquid in the capsule interlayer become thick or near solid-state, the balloon surface shape is solidified relatively, realizes memory; The profile modeling function of air bag helps to guarantee the form precision of curved surface in the invariable zone polishing of curvature of curved surface; Be filled with the dispersion abrasive particle between the free form surface of flexible polishing working face and polished workpiece, utilize of the micro-cutting effect realization polishing of these abrasive particles the surface of the work material; By can regulating the path of magnetic rheology type flexible polisher with air bag, and then realize the polishing process automation in the relative motion on free curve surface work pieces surface to the control of platen movement locus; And by the On-line Control to magnetic rheology type flexible polisher with air bag air bag air pressure, but the material removal amount of flexible modulation polished surface part, polishing tool is apart from the inexactness of die curve apart from control when remedying lathe scanning, help to obtain high shape face dimensional accuracy and stable normal direction polishing force, improve the burnishing surface quality.
The beneficial effect of magnetic rheology type flexible polisher with air bag of the present invention mainly shows:
(1), can control the free form surface of profiling of flexible polishing working face and polished workpiece by electromagnetic field, improve the form precision of polishing;
(2) needn't autogamy drive power, can reduce the weight of manufacturing cost and instrument, and can be used with multiple lathe easily;
(3), by regulating the air pressure of air bag, can control the flexibility of polishing face, polishing tool and free form surface contact area are big, the polishing efficiency height;
(4), the feed distance of each free degree of adjusting platen and air bag air pressure can guarantee that the whole field method of burnishing surface is stable and relatively more even to polishing force, can obtain high polishing quality (it is following that surface roughness reaches Ra0.020 μ m);
(5), by to the control of overflow valve air-flow, the air pressure of control air bag that can be real-time and the normal direction polishing force of curved surface can be implemented in line traffic control;
(6), by gasbag pressure control, can accurately control the local polishing removal amount, carry out that local shape face is accurate to be revised;
(7), the relative position by control platen and unit head digital control, can adjust the distance of polishing tool and polishing workpiece curved surface, thus the automation of realization polishing process.
