Description

Известные способы нарезаки  модифицированных глобоидных черв ков осуществл ютс  при помощи дополнительных движений заготовки и инструмента.The known methods of cutting modified globoid worms are carried out with the help of additional movements of the workpiece and the tool.

В описываемом способе примен ют инструмент, режущие кромки которого смещены относительно осевой плоскости нарезаемого черв ка и относительно оси вращени  Ийструмента на величины, соответствующие заданной модификаций. Это позвол ет исключить дополнительные движени  заготовки и инструм-ента, увеличить жесткость системы и повысить эффективность изготовлени  модифицированных глобоидных черв ков.In the described method, a tool is used, the cutting edges of which are offset relative to the axial plane of the worm being cut and relative to the axis of rotation of the tool by values corresponding to the specified modifications. This makes it possible to eliminate additional movements of the workpiece and tools, increase the rigidity of the system and increase the efficiency of manufacturing modified globoid screws.

На фиг. 1 изображена схема нарезани  черв ка многолезвиевым инструментом; на фиг. же, двум  резцами.FIG. 1 shows a scheme for cutting a screw with a multi-blade tool; in fig. same, two incisors.

Нарезание черв ка осуществл етс  инструментом в виде зубчатых секторов долб ка. Секторы расположены под углом подъема к оси черв ка последовательно на окружности стола станка.The cutting of the screw is carried out by the tool in the form of the toothed sectors of the blade. The sectors are located at an angle of ascent to the axis of the screw in series on the circumference of the machine table.

Режущие кромки инструмента дл  обработки каждой из двух сторон витка черв ка располагаютс  смещенными на величины (di cMetii,) в сторону входа по производ щей поверхности, совпадающей с поверхностью , огибающей входную половину витка исходного черв ка. Каждад кромка инструмента имеет свое определенное смещение относ)1тельно оси вращени  инструмента. Если кажда  из сторон витка имеет одну и ту же модификацию, то смещение режущих кромок инструмента будет симметрично.The cutting edges of the tool for machining each of the two sides of the worm coil are positioned offset by the values (di cMetii) in the direction of the entrance along the production surface coinciding with the surface enveloping the input half of the coil of the original worm. Each tool edge has its specific offset relative to the axis of rotation of the tool. If each side of the coil has the same modification, then the offset of the cutting edges of the tool will be symmetrical.

Режущие кромки многорезадового инструмента, располага сь на производ щей поверхности, могут одновременно располагатьс  на : / поверхности нормальной к виткам черв ка или близкой к нормальной, что обеспечивает примерно одинаковые услови  резани  на обе сторопы витка.The cutting edges of the multi-cut tool, located on the production surface, can simultaneously be located on: / the surface normal to the turns of the screw or close to the normal one, which provides approximately the same cutting conditions for both turns of the coil.
