[0001] The utility model relates to the technical field of bearing shell flanging, in particular to an automatic flanging device for a bearing shell. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment and are widely used in various aircraft. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Therefore, it needs to be connected to the mechanical rotating body by interference fit. However, this fit cannot ensure the axial fixation of the bearing and the mechanical rotating body. It is easy to fall off after working for a long time, especially in aircraft, which seriously affects the safety of the aircraft. Therefore, it is necessary to flanging the bearing with a flanging tool to ensure the axial fixation of the bearing.

[0003] The bearing flanging tools in the prior art usually do not have a positioning sleeve capable of adjusting the position of the bearing, so the bearing is easily damaged during the flanging operation.

[0004] For example, a bearing flanging tool disclosed in Chinese patent CN207447878U is characterized in that the guide sleeve is sleeved in the second step hole and the first step hole through the annular protrusion; a mounting hole is arranged in the middle of the guide sleeve, a positioning shaft is installed in the mounting hole, and the positioning shaft is provided with a fixing seat for installing a blade, and a circular blade is installed on both sides of the fixing seat, and the circular blade is connected to the fixing seat by bolts; the positioning shaft and the fixing seat are integrally formed, so that the position of the bearing is adjusted by the positioning ring to ensure that the bearing is not damaged during the flanging work, and at the same time, the surface finish of the bearing is good after flanging.

[0005] However, after flanging a bearing, the flanging tool needs to be disassembled and a new bearing needs to be installed for flanging, which results in that the bearing cannot be flanging continuously, affecting the efficiency of the bearing flanging work.

[0006] Therefore, we urgently need to provide an automatic flanging device for bearing housings that can perform continuous processing. Utility Model Content
