Description

Technical Field

[0001] The utility model relates to the technical field of bearing auxiliary assembly devices, in particular to a bearing assembly and positioning tool available in multiple sizes. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement and ensure their rotation accuracy. The assembly of bearings is divided into press-in method, uniform knock-in method, machine pressing method, hydraulic sleeve method and temperature difference method according to different operation methods. Among them, the most commonly used method is press-in method, which is efficient and low-cost. However, the press-in method requires ensuring the coaxiality and parallelism of the bearing and the assembly parts so that the bearing can be assembled accurately and easily.

[0003] For example, the Chinese utility model patent application number: 202121509538.7 discloses a bearing outer ring assembly and positioning tool, which relates to the field of bearing assembly technology. The utility model includes an assembly table, a drive device, which is arranged on one side of the upper surface of the assembly table and is used to provide a driving force for the assembly of the bearing inner ring and the bearing outer ring; and a positioning mold, which is sleeved on one side of the upper surface of the assembly table and located below the drive device. The utility model places the bearing outer ring in a cavity formed between an outer limiting cylinder and an inner limiting column, and then sleeves the bearing inner ring onto the inner limiting column, with the lower surface of the bearing inner ring coinciding with the upper surface of the bearing outer ring. This allows the outer limiting cylinder to position the bearing outer ring, and the inner limiting column to position the bearing inner ring, thereby achieving positional positioning of the bearing outer ring and the inner limiting column, thereby preventing the bearing inner ring or the bearing outer ring from being misaligned during continuous tapping, resulting in a mismatch or even misalignment of the two, which in turn leads to damage.

[0004] Although the device in the above patent can limit the position of the outer ring and the inner ring of the bearing, and avoid the misalignment of the inner ring or the outer ring of the bearing during continuous knocking, resulting in incompatibility and damage, in actual use, the structure of the outer limit cylinder and the inner limit column is relatively fixed, and the size cannot be adjusted accordingly according to the diameter of bearings of different sizes, so that the device can only position and assemble bearings of the same size, thereby reducing the overall practicality of the device.
