Description

Technical Field

[0001] The present application relates to the field of cylinder parts, and in particular to a cylinder oil filling nozzle press-fitting device. Background Art

[0002] The traditional method of press-fitting the cylinder oiling nozzle is to use a hydraulic press, a cylinder press-fitting tool, and a press-fitting head to assemble the cylinder oiling nozzle at a fixed workstation. The outer diameter of the existing press head is smaller than the inner diameter of the oiling nozzle, so that the press head will not damage the oiling nozzle when there is a processing error in the oiling nozzle. However, the press-fitting efficiency is slow; and the prior art usually uses a clamp to position the cylinder on the workstation; this operation is more complicated and is not conducive to the installation of the cylinder, and it is easy to damage the cylinder during press-fitting.
