Specific embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, in addition to mutually exclusive feature and/or step, can combine by any way.
Any feature disclosed in this specification, unless specifically stated otherwise, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature is an example in a series of equivalent or similar characteristics.
The input cone contour structures of KRG bunchers are as shown in Figure 1, including left outside round section 1, the conical surface 2 and right cylindrical section 3, the bottom surface of the conical surface 2 of wherein right cylindrical section of 3 place sides is step surface f, the molded line of the conical surface 2 is made up of some circular arcs section, the intersegmental transition circle segmental arc with positioned at bottom of adjacent arc, as shown in Figure 2, the molded line of the whole conical surface 2 structure as shown in Figure 2.
In implementation method once, the processing method of the KRG bunchers of the invention input cone conical surface will be specifically described.
Embodiment
The processing method of the KRG bunchers input cone conical surface, is to carry out the polishing of product conical surface molded line to the conical surface after roughing with grinding machine, and the processing of product conical surface molded line is carried out by the technique.Realize that product conical surface molded line is processed and formed at one time by polishing, compared to traditional use numerical control device by ring Vehicle Processing technique, the positioning step by step of Vehicle Processing step by step is avoided, be it also avoid because the product material hardness finishing difficulty brought high is high, processing roughness is difficult guarantee, the low shortcoming of processing efficiency.
This technique carries out Precision Machining by the polishing molded line to grinder wheel, the polishing demand of product input cone conical surface molded line can be met, product conical surface molded line of the roughness after polishing in below Ra0.1 can be reached, beneficial to the control of product conical surface roughness Ra 0.05 after polishing.General, grinding machine uses high accuracy of the numerically control grinder of high speed to realize polishing, while realizing the on-line checking of bruting process.
The emery wheel of grinding machine has two kinds of designs, and a kind of is that emery wheel is adapted consistent grinder buffing molded line a2 with product conical surface molded line a1 with least one section, conical surface molded line is polished step by step, and the precision for positioning to ensure polishing is carried out before polishing every time.It is quick and facilitate or the emery wheel has and is adapted consistent molded line with product whole conical surface molded line, it is only necessary to which one-time positioning and polishing are capable of achieving the one-shot forming of whole conical surface molded line.The cooperation of product conical surface molded line a1 and grinder buffing molded line a2 is illustrated as shown in Figure 3.
Generally need to carry out roughing to the conical surface before grinding machine polishing is carried out, make the conical surface after roughing that there is allowance, be also to reduce the polishing amount of this technique medium plain emery wheel to reduce the processing capacity of finishing.The characteristics of combination product conical surface molded line, and to realize rough machined cost degradation, its molded line of the conical surface after roughing is the straight line for being reserved with allowance in the present invention, the roughing conical surface molded line af in such as Fig. 2（Dotted line）It is shown.
In order to improve the positioning precision and polishing precision of the installation of grinding machine workpiece as far as possible, before grinding machine polishing, can complete to cylindrical section of two ends of input cone（Cylindrical section 2 of left outside round section 1 as shown in Figure 1, the right side）With the finishing of step surface f, the processing request of finished product is reached.The process of polishing is clamped and with step surface f positioning and clampings with being input into cylindrical section of cone two ends.
Alternatively, it is also possible to while the cylindrical section and step surface f finishing in two ends, complete the processing of input cone internal structure, the rough machined conical surface is only reserved（Roughing conical surface molded line af）, make polishing operation as last one manufacturing procedure.
In the bruting process of high speed grinding machine, grinding machine and workpiece are slowly advanced to be polished, control can be realized by the computer program of grinding machine, the propulsion terminal of polishing is using at the product conical surface one or the width D of many places is calculated as benchmark, its implementation process is designed and completed by the automatic control program of grinding machine, and width D is as shown in Figure 1.
In whole bruting process, the Combined machining state of input cone cone A and emery wheel B is as shown in figure 4, carry out the polishing of product conical surface molded line a1 by the programme-control for moving closer to.Obviously, it is the completion of bruting process, the hardness of emery wheel is necessary more than the case hardness of processing workpiece.
Finally, after completing polishing processing, necessary surface and conical surface polishing are carried out to workpiece.
The processing method of the KRG bunchers input cone conical surface of the invention, as a result of the technique of grinding machine polishing product conical surface molded line, machined by ring compared to traditional use numerical control device, solve Vehicle Processing positioning step by step and machining accuracy is low, processing efficiency is low and high processing costs shortcomings, the problem that workpiece surface hardness is high, difficulty of processing is high is cleverly overcome using grinding machine technique for grinding, is made easy to process and processing efficiency can be greatly improved.
The invention is not limited in foregoing specific embodiment.The present invention expands to any new feature for disclosing in this manual or any new combination, and disclose any new method or process the step of or any new combination.
