Description

Известны инструменты дл  чистовой обработки цилиндрических отверстий иутем их раскатки роликами, установленными под углом к оси опорного конуса. Однако недостатком таких инструментов  вл етс  совмещение рабочей и опорной поверхностей, в результате чего следы износа опорной поверхности ролика перенос тс  на поверхность обрабатываемой детали.There are known tools for finishing machining of cylindrical holes and the method of their rolling with rollers mounted at an angle to the axis of the support cone. However, the disadvantage of such tools is the combination of the working and supporting surfaces, as a result of which traces of wear on the bearing surface of the roller are transferred to the surface of the workpiece.

В описываемом инструменте этот недостаток устранен тем, что наружной поверхности роликов придана форма эллипсоида вращени , соответствующего сечению обрабатываемого цилиндра под углом, равным углу наклона роликов к оси опорного конуса.In the tool described, this disadvantage is eliminated by the fact that the outer surface of the rollers is shaped like an ellipsoid of rotation corresponding to the cross section of the cylinder to be machined at an angle equal to the angle of inclination of the rollers to the axis of the support cone.

На фиг. 1 схематически изображен описываемый инструмент в поперечном разрезе, установленный в обрабатываемом изделии; на фиг. 2- то же, вид в плане; на фиг. 3-разрез по А-А на фиг. 2.FIG. 1 shows schematically the described tool in cross section, mounted in the workpiece; in fig. 2- the same plan view; in fig. 3 is a section along the line A-A in FIG. 2

Описываемый инструмент состоит из роликов /, установленных под углом а к оси 2 опорного конуса 3. Ролики 1 имеют поверхность эллип соида вращени , соответствующего сечению обрабатываемого цилиндра 4 под углом а. Такое выполнение наружной поверхности роликов обеспечивает линейный контакт рабочей поверхности 5 ролика с обрабатываемой поверхностью 6. В цел х разделени  рабочей 5 и опорной 7 поверх ностей на роликах делаетс  кольцева  до зожка щириной в с конусностью , равной конусности опорного конуса, и с незначительным занижением диаметра ролика. Эта опорна  поверхность 7 роликов непосредственно не участвует в процессе калибровани  и ее износ с точки зрени  шероховатости обрабатываемой поверхности не имеет существенного значени .The described tool consists of rollers / installed at an angle a to the axis 2 of the support cone 3. The rollers 1 have an elliptical rotation surface corresponding to the section of the cylinder 4 being machined at an angle a. This embodiment of the outer surface of the rollers ensures a linear contact of the working surface 5 of the roller with the surface to be treated 6. In order to separate the working 5 and supporting 7 surfaces, the rollers make an annular ring to the curvature of the taper, equal to the taper of the supporting cone, and with an insignificant understatement of the roller diameter . This bearing surface 7 of the rollers does not directly participate in the calibration process and its wear is not significant from the point of view of the roughness of the surface being processed.

Предмет изобретени Subject invention

Инструмент дл  чис-товой обработки цилиндрических отверстий nvтем раскатки роликами, установленными под углом к оси опорного конуса , отличающийс  тем, что, с целью образовани  раздельных опор - ОЙ и рабочей поверхностей роликов, наружной поверхности последних придана форма эллипсоида вращени , соответствующего сечению обрабатываемого цилиндра под углом, равным углу наклона роликов к оси опорного конуса.The tool for numerical processing of cylindrical holes, nv, is the rolling with rollers mounted at an angle to the axis of the support cone, characterized in that, in order to form separate supports — OH and working surfaces of the rollers — the outer surface of the latter is shaped like an ellipsoid of rotation corresponding to the section of the cylinder to be worked angle equal to the angle of the rollers to the axis of the support cone.
