1st, whole cutter head is designed to a part, as shown in Figure 1, first establishing cutter head flange 2 and the three-dimensional of base 1
Model；
2nd, as shown in Fig. 2, additionally setting up the babinet of a spoke in addition to cutter head flange and base threedimensional model
Model；Spoke babinet model is inserted into substructure model part, positioning is constrained, is then synthesized with boolean operation method
One；
3rd, as shown in figure 3, selecting different faces that it is integrally taken out shell according to design requirement, take out thickness of the shell and drawn according to thickness of slab
Point；
4th, division surface 4 is established, one-piece parts are divided into using split plot design by splicing part not of uniform size, its main feature is that still
It is an one-piece parts, but the cut-off rule on part body is obvious；
5th, continue to establish stretching etc. in the diverse location of model, complete some secondary soldering parts on cutter head, only not
It is presently not part to cross, and is mainly characterized by new feature foundation and amalgamation result is not required, cut in this way, just being generated between feature
Intersection；
6th, after all features are completed, chamfering is carried out using " isolated " method to the feature after each cutting, it is therefore an objective to
Form the groove size of connection requirement；
7th, after completing above-mentioned task, part is preserved, completes the welding figure of whole cutter head；
File in 7th step, is separately saved as extending the file of entitled x_t by the 8th, part map generalization, then opens x_t texts
Part, at this time finds that all features are all inputs 1, input 2 ... ... until inputting N, completes the importing of all parts, at this moment
Can disassemble into the part of N number of welding as requested, such as it is exactly a part to input 1, using Low market efficiency method by its
Remaining all inputs are deleted, and are then separately saved as a part, and so on, all independent parts just generate；
9th, the design of whole part drawings is completed on the basis of being mended the 8th, then carry out successive projects figure goes out figure work.
One embodiment of the present of invention is described in detail above, but the content is only the preferable implementation of the present invention
Example, it is impossible to be construed as limiting the practical range of the present invention.All all the changes and improvements made according to the present patent application scope
