Turning and processing device of bearing inner ring and processing method

Abstract

The invention aims to provide a turning and processing device of a bearing inner ring and a processing method. The turning and processing device of the bearing inner ring comprises a turning and processing device body, an inner hole clamping device and a device for adjusting and stabilizing the front end position of the bearing inner ring, wherein when the turning and processing device of the bearing inner ring works, the device for adjusting and stabilizing the front end position of the bearing inner ring is used for adjusting the front end position of the inner ring and enabling the front end surface of the inner ring to be compacted on a standard blocking surface; the inner hole clamping device is used for clamping an inner hole of the inner ring; and the turning and processing device body is used for performing processing on the outer periphery of the inner ring, the outer periphery and the rear end surface of an end baffle ring, an oil groove and the rear end surface of the innerring. According to the turning and processing device of the bearing inner ring disclosed by the invention, the axis of the inner hole and the perpendicularity of the front end surface of the inner ring are convenient to adjust; and in the turning and processing course, the axis of the inner hole and the perpendicularity of the front end surface of the inner ring are high in stability, and the processing precision of the outer periphery of the inner ring, the outer periphery and the rear end surface of the end baffle ring, the oil groove and the rear end surface of the inner ring are high.

Description

technical field [0001] The invention relates to the field of bearings, in particular to a bearing inner ring turning processing device and processing method. Background technique [0002] The front end of the inner ring of the roller bearing is provided with an end stop ring; after machining the inner hole of the inner ring and the front end face of the inner ring, the outer circle of the inner ring and the outer circle of the end stop ring need to be machined based on the inner hole and the front end face and the rear end face, oil groove and the rear end face of the inner ring; when the inner ring of the traditional turning device is held, there is troublesome adjustment of the verticality between the inner hole axis and the front end face of the inner ring and the inner hole axis and the inner ring during the turning process. The verticality stability of the front end face is poor, which leads to the shortage of low machining accuracy of the outer circle of the inner ring...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the troublesome adjustment of the perpendicularity between the axis of the inner hole and the front end surface when the inner ring of the current turning device is held, and the stability of the perpendicularity between the axis of the inner hole and the front end surface during the turning process is relatively poor, resulting in The outer circle of the ring, the outer circle of the end retaining ring and the rear end surface, the oil groove and the rear end surface of the inner ring have low machining accuracy, and it is convenient to adjust the verticality of the axis of the inner hole and the front end surface during the turning process. The verticality stability of the axis of the inner hole and the front end face of the inner ring is better, and the outer circle of the inner ring, the outer circle of the end retaining ring and the rear end face, the oil groove and the rear end face of the inner ring have higher machining accuracy.
