Description

внутреннего кольца, обрабатываема инструментом 5, базируетс по торцу на торец шпиндел 3 {осева опора) и по внутренней поверхности на закрепленную соосно со шпинделем оправку с наружным цнлнндрнческим по ском Т (вращающа с радиальна опора с цилнндрической онорной поверхностью 7).The inner ring, machined with tool 5, is based on the end face on the end face of the spindle 3 (axial support) and on the inner surface on the mandrel with the outer core (rotating radial bearing with cylindrical on the tip surface 7) fixed coaxially with the spindle.

Устройство работает следующим образом.The device works as follows.

Заготовка 4 или 4, Ноджата роликом 9 к цилиндрической опорной новерхности 7 (7), к неподвижной радиальной опоре 8 и к торцу щпнндел 3 приводитс во вращение, прн этом ведение осуществл етс по торцу и по цилиндрической поверхности. Заготовка обкатываетс ио опорной поверхности 7 (}. Однако указанное обкатывание благодар небольщой разности диаметров заготовки и опорной поверхности 7 (} происходит между поверхиост ми одинаковой по знаку и близкой по величине кривизны. Удельное давление невелико , что сводит к минимуму накатывание цилиидрической новерхности.A blank 4 or 4, Nodjata with a roller 9 to the cylindrical bearing surface 7 (7), to the fixed radial support 8 and to the end of the clamp 3, is rotated, this guidance is performed on the end and on the cylindrical surface. The workpiece is rolled around the supporting surface 7 (}. However, the specified rolling due to a slight difference in the diameters of the workpiece and the supporting surface 7 (} occurs between surfaces of the same sign and similar curvature. The specific pressure is small, which minimizes the ciliane surface rolling.

Claims

1. A device for positioning and rotating parts of a rolling ring bearing ring containing a spindle, an axial bearing, a fixed radial bearing, a rotating radial of the bearing with a cilidric bearing surface, and means for pressing the details onto said axial and radial supports, characterized in that higher machining accuracy, axial and rotating radial bearings are rigidly connected to each other and mounted on a spindle mounted on the equipment, in this case the diameter of the cylindrical supporting surface of the rotating radius noy support selected from conditions possibilistic its movement relative to the base with a gap noverhnosti workpiece.

2. A device according to claim 1, characterized in that the cylindrical bearing surface of the rotating radial bearing is made up of a ring enclosing the workpiece.

3. A device according to claim I, characterized in that the cylindrical bearing surface of the rotating radial bearing is made as a mandrel entering the workpiece opening.
