Abstract
A grinding processing method for swing, makes part can do reciprocal circle swing on grinding machine, and the amplitude of swing is exactly the relative arc length needing grinding skin; Arc groove is designed, according to the angle of surface to be machined determination arc groove at index dial; Disk connecting machine tool and part, disk is provided with centering face K, and K face determines the start angle of grinding, and M determines in hole the position of backing pin, the center of centering cylindrical determination part; Part to be processed is arranged on positioning disk, the angular position that the part that angle pin is determined is installed, the center of centering part; With pressing plate, part is clamped; Centering fixture K face, determines the start angle of grinding; Start lathe, swing handle, completes a grinding; Unclamp pressing plate, take out latch, rotational positioning dish carries out calibration, repeats next grinding process.Advantage of the present invention: the machining accuracy and the processing stability that promote part, ensure the finish of part finished surface, enhance productivity.
Description
Technical field
The swing grinding that the present invention relates to inside and outside circle processes the inside and outside circle intermittent grinding process be mainly used in aviation machine manufacture field, particularly a kind of grinding processing method of swing.
Background technology
Grinding is an important processing method in machining manufacturing industry.Shaping from initial blank of complicated engine part, the more just can complete in road through roughing, half fining-off, fining-off, fine finishining etc., and a kind of very ripe method that grinding is most widely used in finishing step just.Grinding is exactly often last procedure of workpiece, determines the performance attractive in appearance of product final accurate performance, physical property, serviceability and product, determines quality and the value of product.Along with the continuous lifting of Engine Quality, the precision of parts and surface quality are had higher requirement.For manufacturing of such class part, traditional method is all more clumsy.General is all rough mill shaping by the method for milling by the shape of part, carries out manual pincers on this basis and repaiies and polishing grinding.Although the part size processed like this meets designing requirement, the finish of piece surface but can not meet the demands.Also be very high to the requirement of the technical merit of operator in addition, and labour intensity is large, crudy change at random is larger.
Summary of the invention
The object of the invention is the precision in order to improve parts and surface quality, spy provides a kind of grinding processing method of swing.
The invention provides a kind of grinding processing method of swing, it is characterized in that: the grinding processing method of described swing, the outer round surface of part is the surface needing grinding, outer surface there are 8 boss, normal cylindricalo grinding is made to be difficult to realize, the grinding processing method of described swing, makes part can do reciprocal circle swing on grinding machine, and the amplitude of swing is exactly the relative arc length needing grinding skin;
Main technical schemes is:
The design of arc groove: arc groove is the key component of swing grinding, designs arc groove at index dial, according to the angle of surface to be machined determination arc groove, the precision of angle is determined according to element precision, and 8 uniform holes are index holes;
The design of disk: disk connecting machine tool and part, disk is provided with centering face K, and K face determines the start angle of grinding, and M determines in hole the position of backing pin, the center of centering cylindrical determination part;
Positioning disk ensures the correct installation site of part, ensures the correctness of part calibration;
Part to be processed is arranged on positioning disk, the angular position that angle pin determination part is installed, the center of centering part; With pressing plate, part is clamped; Centering fixture K face, determines the start angle of grinding; Start lathe, swing handle, completes a grinding; Unclamp pressing plate, take out latch, rotational positioning dish carries out calibration, repeats next grinding process.
The position of described calibration latch is two, does not affect the processing of part when ensureing calibration.
Described positioning disk and the gap of back-up ring will ensure by adjusting, and guarantee to rotate flexibly, without catching phenomenon.
Advantage of the present invention:
The grinding processing method of swing of the present invention, in whole grinding process, bistrique does High Rotation Speed, and surface to be machined does reciprocal swing.Promote machining accuracy and the processing stability of part, ensure the finish of part finished surface.Substitute manual operations with mechanization, reduce the labour intensity of operator to greatest extent, enhance productivity significantly.Promote the machining accuracy of part widely, improve technology difficulty, promote stability, the optimizing machining technology environment of part quality, improve working (machining) efficiency: substitute with machining process and make by hand.
