Description

Technical Field

[0001] The utility model relates to the technical field of ball expansion plug installation, in particular to a ball expansion plug installation tool. Background Art

[0002] The ball expansion plug, full name ball expansion high pressure plug, is a part that uses the pressure / expansion principle to seal the fluid channel of hydraulic and pneumatic components. In the past, the installation method of the ball expansion plug was to manually hammer the punch, which is not easy to operate and easily damages the surface of the workpiece, and embed the steel ball into the sleeve; the sleeve expands radially to form an effective high-pressure leak-free seal. In order to save labor and ensure the sealing effect, the prior art proposes a device that uses a machine to press the ball expansion plug in. The utility model patent with the authorization announcement number CN210306594U, a ball plug press, is a ball expansion plug installation device. However, when using the ball plug press, workers still need to align the ball plug 3 with the output end of the telescopic cylinder 5 to ensure the installation of the ball plug 3. Before the ball plug 3 is installed, if the ball plug 3 is too far away from the output end of the telescopic cylinder 5, it will increase the difficulty of the worker's alignment. If the ball plug 3 is too close to the output end of the telescopic cylinder 5, the output end of the telescopic cylinder 5 will easily knock off the steel ball of the ball plug 3; the ball plug press is still inconvenient to use.
