Description

Technical Field

[0001] The utility model is designed in the field of the technical field of retaining spring installation, in particular to a small retaining spring installation machine. Background Art

[0002] The circlip is pressed into the circlip groove of the workpiece. Since the surface roughness standard of the shaft with the circlip groove is extremely high, in order to ensure that the workpiece surface is not scratched, a tapered sleeve is required to be sleeved on the outside of the workpiece (shaft). The circlip is pressed into the circlip groove with a manual pressure tool on the outside of the sleeve to avoid scratching the shaft surface. Since the sleeve is sleeved on the shaft, the circlip is pressed through the sleeve, and the diameter of the circlip increases significantly. The design requires that the diameter of the circlip after processing is φ12.6. Now the diameter of the circlip after the sleeve is pressed has reached φ16.1. Because the circlip fatigue cannot shrink, it is manually clamped and restored with pliers, which has high labor intensity and low work efficiency. In addition, during the clamping process, if the jaws slip off the circlip, the workpiece will be scratched and scrapped, and the cost will increase accordingly. Utility Model Content
