Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing equipment, in particular to an automatic filling device for a micro bearing ring. Background Art

[0002] Miniature bearings mainly refer to various types of bearings with an outer diameter of less than 9 mm. These bearings are mostly made of carbon steel, ceramics, stainless steel and other materials, and are commonly used in various industrial equipment and a variety of smaller equipment. In production, a double-end surface grinder is required to grind and polish the inner and outer rings of miniature bearings. It is necessary to manually place the bearing ring into the grinding toothed disc (the outer and inner rings of the bearing ring correspond to grinding toothed discs with different apertures), and then place the grinding toothed disc into the double-end surface grinder to grind the bearing ring.

[0003] For example, the application number is 202222441769.X, which is an automatic bearing ring filling device for micro bearing grinding. The device quickly installs the grinding toothed disc on the tray, and then quickly installs the tray on the slide. The grinding toothed disc is driven into the drum through the traction mechanism, and the lifting plate lifts the bearing ring so that the bearing ring continuously falls on the grinding toothed disc. With the vibration of the grinding toothed disc, the bearing ring will eventually fall into each through hole of the grinding toothed disc, thereby improving the filling effect and filling efficiency of the grinding toothed disc. However, after analyzing the above-mentioned comparative patents and some existing automatic bearing ring filling devices, it was found that the device drives the rings to be filled by rolling the drum, and the bearing rings are difficult to be evenly distributed in the through holes, and the filling effect is poor. At the same time, it is difficult to achieve a good filling effect when changing the ring size.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a micro bearing ring automatic filling device is proposed. Utility Model Content
