Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic mechanisms and relates to a hydraulic mechanism for quickly pressing and locking edges of a joint ball of a joint bearing. Background Art

[0002] The spherical plain bearing has an inner spherical surface and an outer spherical surface on its sliding contact surface. It can rotate and swing at any angle during movement. It is made by using a variety of special process treatment methods such as surface phosphating, blasting, padding, spraying, etc. The spherical plain bearing is manufactured by pressing it with a hydraulic mechanism. When the existing spherical plain bearing inner joint ball is quickly pressed, the outer ring and the inner ring are manually taken at the same time and placed on the pressing table for work.
