Description

Technical Field

[0001] The utility model relates to the technical field of bearing installation, in particular to a main shaft bearing pressing device. Background Art

[0002] A spindle bearing is a mechanical element that limits relative motion to a desired range of motion and reduces friction between moving parts. It can provide free linear motion of a moving part or free rotation about a fixed axis, or it can prevent motion by controlling the vector of the normal force acting on the moving part.

[0003] Most of the existing spindle bearing clamping devices do not have a clamping mechanism when in use, which makes it inconvenient to align the bearing. Therefore, some people will set a clamping block under the device to clamp the spindle bearing. For example, the Chinese utility model patent with announcement number CN218800297U specifically discloses a bearing installation clamping device.

[0004] However, in actual use of the clamping device, people will find that the device uses the elastic force of the spring to push the clamping block to clamp the spindle bearing, but this clamping mechanism is very unstable. Since the clamping block is not restricted, it is easy to deviate during the clamping process, and the fixing effect is poor. Utility Model Content
