Technical Field

[0001] The invention relates to the field of welding facilities, and in particular to a bearing seat welding device. Background Art

[0002] Bearings are components that fix and reduce the load friction coefficient during mechanical transmission. In other words, when other parts move relative to each other on the shaft, the bearings are used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies and reduce the mechanical load friction coefficient of the equipment during transmission. According to the different friction properties of the moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings.

[0003] Bearings often use bearing seats to support the bearings during use. During the production of the bearing seats, it is often necessary to weld mounting ears on both sides of the bearing seats to facilitate the subsequent installation and fixation of the bearing seats.
