Description

Technical Field

[0001] The utility model relates to the technical field of bearing production, in particular to a bearing hole punching device. Background Art

[0002] Bearings are an important component used to support the rotating shaft of a machine. They are usually composed of an inner ring, an outer ring, rolling elements and a cage. Bearings enable the smooth operation of mechanical equipment by reducing friction between rotating parts and providing support. Different types of bearings are suitable for various applications, such as automobiles, aerospace, industrial machinery, etc. The outer ring or inner ring of the bearing needs to be punched to form lubrication holes and mounting holes. The lubrication holes are used to provide lubricating oil or grease to the inside of the bearing, and the mounting holes are used to facilitate the installation and fixation of the bearing.

[0003] However, the existing bearing hole punching equipment only clamps and fixes the outer ring or inner ring of the bearing from the inside before punching to facilitate punching. However, since the outer ring or inner ring of the bearing is circular, only one clamping method is used, which may easily cause the outer ring or inner ring of the bearing to rotate or axially displace, thereby affecting the punching process. Moreover, if multiple holes need to be punched on the outer ring or inner ring of the bearing, the fixed outer ring or inner ring of the bearing cannot be moved, and needs to be loosened, changed in position, and then re-fixed to change the punching position, which is time-consuming and labor-intensive, and the punching efficiency is low.
