Background technology
Along with the demand of machine components is more and more diversified, corresponding mechanical process technique is also in continuous progress.Longaxones parts is being added man-hour; Traditional process is to be processed as the master with turning mostly; Particularly lateral surface being contained step class, lateral surface is that the curved surface uiform section is circular longaxones parts; Adopt turning to process that diameter of axle step appears in the product regular meeting that this traditional process processes, surface roughness is poor, and the diameter of axle because of the stressed generation distortion of turning, form variety of issue such as waist fermented soya beans, salted or other wise shape, and production efficiency is low; The cutter sharpening angle is required height, operator's level of skill is also had relatively high expectations.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of process of utilizing the centreless grinding lathe that major axis class lateral surface is processed.Can effectively solve the problems such as product roughness difference that produce because of traditional diamond-making technique.
A kind of cross section is the processing method of the major axis of circle, has utilized the centreless grinding lathe, and step is following:
A. emery wheel and guide wheel are cut in polishing: the cutting emery wheel and the guide wheel that utilize processing unit (plant) polishing centreless grinding lathe; The lateral surface of emery wheel and the lateral surface of major axis final finished are complementary; The bus and the contact wire that are longaxones parts final finished to be processed can be fitted everywhere, the bus that described contact wire is meant finished product respectively with processing after guide wheel, the cutting emery wheel after the processing contact formed curve;
B. install: the supporting plate of centreless grinding lathe is positioned in the middle of cutting emery wheel and the guide wheel, and is positioned on the plane that the two central axis constitutes, and longaxones parts to be processed is placed on the supporting plate that cuts between emery wheel and the guide wheel;
C. locate: the adjustment backstay, part to be processed is moved forward and backward, arrive cutting emery wheel and the guide wheel place that is complementary with this size to confirm part axial size to be processed;
D. cutting forming: depress centreless grinding handle mobile idler pulley and drive longaxones parts rotation to be processed, the direction of rotation of cutting emery wheel is opposite with the direction of rotation of longaxones parts to be processed, to realize cutting the grinding that emery wheel is treated processing parts.
The present invention realizes the control to the profile of longaxones parts to be processed through the profile of polishing cutting emery wheel and guide wheel, has solved the normal problem that occurs of conventional machining process.Compare with the processing technology of traditional handicraft; Present processing method has improved working (machining) efficiency than method for turning in the past, reduced processing cost, and this process is less demanding to operator's level of skill; Easy to process, quick, reduced the difficulty of processing of this product; The accuracy of manufacture, surface quality and properties of product have all obtained improving greatly simultaneously.And processing method of the present invention is simple and direct, and is easy to implement, and effect is remarkable, can extensively promote at the machine-building manufacture field.

The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described:
A kind of cross section is the processing method of the major axis of circle, has utilized the centreless grinding lathe, and step is following:
A. emery wheel 2 and guide wheel 3 are cut in polishing: the cutting emery wheel 2 and guide wheel 3 that utilize emery wheel processing unit (plant) polishing centreless grinding lathe; The cutting emery wheel 2 and the lateral surface of guide wheel 3 and the lateral surface of major axis final finished are complementary; The bus and the contact wire 5 that are longaxones parts 1 final finished to be processed are fitted everywhere; With the contact wire 5 of processing back guide wheel 3, cutting emery wheel 2 can be everywhere, the bus that described contact wire 5 is meant finished product respectively with processing after guide wheel 3, the cutting emery wheel 2 after the processing contact formed curve;
B. install: the supporting plate of centreless grinding lathe is positioned in the middle of cutting emery wheel 2 and the guide wheel 3, and is positioned on the plane that the two central axis constitutes, and longaxones parts 1 to be processed is placed on the supporting plate between cutting emery wheel 2 and the guide wheel;
C. locate: adjustment backstay 4, longaxones parts 1 to be processed is moved forward and backward, cut emery wheel 2 and guide wheel 3 places accordingly to confirm that longaxones parts 1 axial location to be processed arrives with this position;
D. cutting forming: depress centreless grinding handle mobile idler pulley 3 and drive longaxones parts 1 rotation to be processed, the direction of rotation of cutting emery wheel 2 is opposite with the direction of rotation of longaxones parts to be processed 1, to realize cutting the grinding that emery wheel 2 is treated processing parts.
As improvement of the present invention, the cutting emery wheel 2 among the described step a can process coarse plain emery wheel, fine grinding wheel respectively, then part is processed with fine grinding wheel after with the coarse plain emery wheel cutting forming again.Adopt coarse plain emery wheel to increase work efficiency greatly, carry out the surface smoothness of fine grinding wheel processing can raising longaxones parts 1 finished product to be processed again.Both can increase work efficiency the combining of coarse sand and fine sand moulding, also guarantee the quality of processed finished products simultaneously.
As more common longaxones parts to be processed; The part that has step on the axis body to final products adds man-hour; Need cut relevant position on emery wheel 2 and the guide wheel 3 and process the circular step that the final products profile with longaxones parts 1 to be processed is complementary.
When if the lateral surface of longaxones parts final products to be processed is curved surface, then final products are complementary with guide wheel 3, the bus of cutting emery wheel 2 and the bus of final products respectively, and contact wire 5 is identical with the shape of generatrix of final products.
