Description

Technical Field

[0001] The utility model relates to the technical field of snap ring pressing equipment, and particularly relates to a snap ring pressing device. Background Art

[0002] At present, as a commonly used limiting workpiece, a snap ring is installed in the shaft grooves of machines and equipment to prevent the axial movement of parts on the shaft. Usually, the snap ring needs to be pressed into the shaft groove. The traditional method of pressing the snap ring is manual pressing. This traditional snap ring pressing method is time-consuming and laborious. In the actual pressing process, it is easy to occur that the pressing amount is excessive, resulting in damage to the bearing and the snap ring. And manual pressing may cause safety accidents such as the operator's hand being pressed, with insufficient safety. At the same time, the pressing efficiency is low and cannot meet the requirements of the production line.

[0003] In the utility model patent with the publication number of 208713309U and the patent name of "A New Type of Snap Ring Pressing Device", a snap ring pressing device is proposed based on the above problems. After the snap ring is pressed in this device, the pressing head device rises, and the operator takes out the snap ring cylinder. The snap ring cylinder feeding mechanism returns to the original position to prepare for the next work. In addition, before pressing in this device, the worker needs to place the workpiece to be processed on the fixture mechanism. In this device, not only does the worker need to place the workpiece well, but also after the pressing is completed, the worker needs to put the snap ring cylinder back to its original place, which is time-consuming and laborious.

[0004] Therefore, a snap ring pressing device is proposed. Summary of the Utility Model
