Description
Technical field
The present invention relates to a kind of Digit Control Machine Tool, and in particular to a kind of numerical control ball pin lathe.
Background technology
With developing rapidly for industrial technology, Computerized Numerical Control processing technology is with its strong vitality in modern mechanical processing
In occupation of irreplaceable position.Digital control processing can make operator from cumbersome and labor as a kind of machining based conception of new model
Free, become before also preventing much by swinging handle from the product processed for reality in tired manual labor.It can be said that
Digital control processing is a great revolution of modern processing industry, and it can not only mitigate the labor intensity of operator, obtain high-quality processing
Product, in the modern society that efficiency is most important, digital control processing, which is enterprise, be also operator has won second of life.
For the processing of ball part, following several method is generally used at present：
1st, artificial process；
Artificial process is workman by sensation, the depth of cut hand-manipulated and feed, and manual car goes out spherical shape.It is some experienced
Senior technician can pass through and process the sphere of standard by hand.But the method requires high to operating personnel, and machining accuracy is complete
Feel by hand, not only precision is not high, and process velocity is slow, and efficiency is low.
2nd, pattern method；
The operation principle of pattern method is：By increasing a surface model, the bearing touch with the axial feed shaft rear end of cutterhead, limit
The feed path of cutterhead processed, processes sphere.
3rd, modulus method is worn；
The operation principle for wearing modulus method is identical with pattern method, and simply curve mold mounting means is different.Modulus method is worn using cutterhead axial direction
Walk to fix a pin on cutter shaft, through in the curved surface of mould, limit the feed path of cutterhead, process sphere.
Pattern method and wear modulus method and use engine lathe.Compared to numerically controlled lathe, the processing efficiency of engine lathe is higher, to behaviour
It is relatively low as personnel requirement.Under square one, production efficiency can be greatly improved using engine lathe, reduction is produced into
This, increases economic efficiency.
4th, interpolation
During using lathe in machining, because work piece sphere is imperfect, there is centrifugal force during machine tool running, rotating speed should not mistake
Height, causes processing efficiency not high；In addition interpolation principle is used during digital control processing arc surface, therefore machining accuracy is not also high.
To find out its cause, during lathe in machining spheroid, its circular trace is by two rectilinear coordinates（X, Z）Circular arc insert
Mend what function was completed, therefore the two rectilinear coordinates（X, Z）Numerical control positioning precision error, will be directly reflected into circular arc insert
The circularity of circular trace is mended, so as to have influence on the circularity of processed spheroid.
The circular interpolation of numerically controlled lathe is completed by the movement simultaneously of two rectilinear coordinates of X, Y, and X-coordinate movement has one
Individual commutation process, so, the opposite clearance error of the coordinate just influence whether circular trace, so as to have influence on processed spheroid
Circularity.
To sum up, the efficiency of existing lathe in machining spheroid is low, error is big, it is impossible to meet current automobile industry, optics
The process requirements of the increasingly increased high-accuracy ball pin of the hardware industries such as industry, water heating valve, hydraulic pressure and ball part.
