Bearing inner ring cold mill

Abstract

The invention relates to the field of bearing manufacturing equipment, and the purpose is to provide a bearing inner ring cold mill which is convenient in material loading and unloading and has a high efficiency during bearing inner ring processing, and the processed bearing inner ring has good compactness and a longer service life. The bearing inner ring cold mill comprises a lathe body, a connecting seat, a mounting seat, a supporting seat, a grinding wheel, a wheel shaft, a grinding wheel driving device, a swing driving device, a feeding device, a loading and unloading mechanical arm and a blanking groove, wherein the connecting seat is fixedly connected with the lathe body, and the mounting seat is hinged with the connecting seat; the supporting seat is provided with two supporting wheels and is fixedly connected with the lathe body; the grinding wheel is matched with the two supporting wheels to be used for grinding the external circle of the bearing inner ring and a roller raceway, and the periphery of the grinding wheel is provided with a grinding bulge loop; the grinding wheel driving device is used for rotating the grinding wheel and is fixedly connected with the mounting seat, and the swing driving device is used for swinging the mounting seat; the grinding wheel is sheathed outside the wheel shaft and is fixedly connected with the wheel shaft; and the wheel shaft is pivoted with the mounting seat. The bearing inner ring cold mill is convenient in material loading and unloading and has the high efficiency during bearing inner ring processing.

Description

technical field [0001] The invention relates to the field of bearing manufacturing equipment, in particular to a bearing inner ring cold rolling machine which is convenient for loading and unloading during processing of the bearing inner ring, has high efficiency, and has good compactness and long service life of the processed bearing inner ring. Background technique [0002] The outer circle of the inner ring of the bearing needs to process the outer circle and the raceway, and the processing accuracy is relatively high; the invention of Chinese patent announcement number CN 101513677A discloses a forming tool for the outer circle of the inner ring of the precision bearing, including a handle and a blade, and the handle includes A handle, the upper end of the handle is provided with a joint, used to install the blade; The surface processing part between the chamfers is formed, and an arc-shaped protrusion is arranged in the middle of the surface processing part. The invent...
