Abstract
The invention discloses a machining method for a special-shaped part and belongs to the technical field of machining. The machining method for the special-shaped part comprises the specific steps: S1, after positioning a to-be-machined special-shaped part, generating a clamping force through a clamping mechanism; S2, putting the positioned workpiece on a numerical control turning machine tool and turning the surface of the workpiece; S3, after turning, using an abrasive belt to grind the surface of the workpiece which is turned; S4, after grinding, grinding the surface of the inner surface of the workpiece smoothly by using a diamond roller to clean; and S5, soaking the thoroughly cleaned workpiece in a chemical solution and removing burrs on the surface of the workpiece by virtue of chemical action. By adopting an abrasive belt grinding process, the machining method has the advantages of being low in machining temperature and low in roughness height, and the to-be-machined part has a good surface quality, so that a grinding burn phenomenon which is hard to avoid in curve grinding of an abrasive wheel is avoided.

Technical field
The present invention relates to machining technology field, specially a kind of machining process of irregular part.
Background technology
Tool processing refers to the process of that the appearance and size or performance of workpiece are changed by a kind of plant equipment.Mechanical heat
Processing cold working can be divided into machining and pressure processing by the difference on processing mode.Hot-working is common heat treatment, forging,
Casting and welding.With the fast development that modern mechanical is processed, mechanical manufacturing technology is fast-developing, slowly emerged many
Advanced mechanical manufacturing technology method, such as micro-machining technology, RP technique, precision and ultra-precision machining technology
Deng.
The processing of Parts with Special shaped Section generally has three kinds of approach：1. direct forming method, such as cast, forging, punching press；2. cutting is transported
Dynamic synthetic method, such as car, milling, plane, mill；3. special process method, such as wire cutting, electric spark, Laser Processing.Wherein, directly into
Shape method is the main manufacturing process of Parts with Special shaped Section, but because its accuracy of manufacture is relatively low, surface roughness value is larger, it is impossible to full
The finishing requirements of sufficient Parts with Special shaped Section.Special process method is because efficiency is low, high cost and can not process axial cross section shape and answer
Miscellaneous non-circular sections part and its application is subject to a definite limitation.Therefore, motion synthetic method machining is to obtain different in high precision
The main path of type section parts.Car, milling, plane, mill etc. are most common motion synthesis cutting working methods, can be processed not
Same complicated shape part.In these methods, milling and planing is still difficult to obtain machining accuracy very high at present.Grinding is normal
Precision machining method, and with production efficiency higher, but plain grinding processing because emery wheel abrasive particle negative rake is larger, cut
Cut that thickness is small, abrasive particle is easily passivated, chip easily blocks that emery wheel, grinding temperature are high, grinding force is big, it is big to be difficult to competent grinding Curvature varying
The reason such as workpiece, its application is subject to a definite limitation.Precision turning is to develop precision processing technology faster in recent years, especially with
The extensive use of Digit Control Machine Tool and diamond cutter, the machining accuracy of precision turning and processing efficiency is greatly improved.Therefore,
Come into operation we have proposed a kind of machining process of irregular part, to solve the above problems.
The content of the invention
It is an object of the invention to provide a kind of machining process of irregular part, to solve to be carried in above-mentioned background technology
The existing machining for going out is difficult to obtain the problem of machining accuracy very high.
To achieve the above object, the present invention provides following technical scheme：A kind of machining process of irregular part, this is different
The machining process of type part is comprised the following steps that：
S1：After by special-shaped part positioning to be processed, clamping force is produced by clamp system, workpiece is kept accurately fixed
Position position；
S2：Workpiece after positioning is placed on numerical control turning lathe, turnery processing is carried out to workpiece surface；
S3：After completing turnery processing, using abrasive band to being ground by the workpiece surface after turnery processing；
S4：By after grinding, being cleaned after its surface is polished smooth to workpiece inner wall using emery wheel；
S5：The workpiece that will be cleaned up is immersed in chemical solution, is removed the burr of workpiece surface by chemical action.
Preferably, in the step S1, the application point of clamping force should fall in workpiece rigidity preferably direction and position, and lean on
The machined surface of nearly workpiece.
Preferably, in the step S2, when turnery processing is carried out to workpiece, the operating angle of turning cutting tool and motion and
Installation site and the cross sectional shape of work are related, and the cutter front-and-back angle of turning changes with the change in shape of workpiece.
Preferably, in the step S3, abrasive band is made up of contact wheel, pressure nog plate and contact lining band, and contact wheel, pressure nog plate
Splice grafting touches lining band can arbitrarily be changed by the curve form of part, it is kissed with curve surface of workpiece well in grinding process
Close, obtain preferable molding effect.
Preferably, in the step 5, chemical solution is the mixed liquor of hydrochloric acid, phosphoric acid, sulfuric acid, hydrochloric acid diyl aniline and water,
Wherein hydrochloric acid：Phosphoric acid：Sulfuric acid：Hydrochloric acid diyl aniline：Water=0.5:1.2:0.4:0.2:20.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention uses sbrasive belt grinding technique, with processing temperature
The low and low advantage of roughness value, can make part to be processed obtain good surface quality, overcome and be difficult in emery wheel curve surface grinding
The grinding burn phenomenon for avoiding, the chemical method of use removes the burr of workpiece surface, in chemical solution, workpiece surface
During metal will go to solution in the form of the ion, and workpiece surface is gathered in, after chemical reaction forms that one layer of resistance is big, conductance
The small mucous membrane of rate, protects workpiece surface not to be corroded, and burr protrudes workpiece surface, is removed it after after chemical reaction.
