Abstract

The invention discloses electric hydraulic riveting tongs which comprise an arch body and a piston. The piston is connected with the arch body in a sliding mode. The riveting tongs further comprise a hydraulic oil cylinder, a hydraulic oil connection ball and a hollow nut. The upper end of the hydraulic oil connection ball is connected with the hollow nut, the lower end of the hydraulic oil connection ball is connected with the hydraulic oil cylinder, and the hollow nut is connected with a nut of the hydraulic oil cylinder. The electric hydraulic riveting tongs have the advantages that the size is small, weight is low, riveting is firm, and service life is long.

Description

[0001] technical field [0002] The invention relates to a riveting pliers, more precisely an electro-hydraulic riveting pliers. [0003] Background technique [0004] Such as figure 1 , figure 2 As shown, the riveting pliers in the prior art include a bow body 1, a piston 2, an old hydraulic cylinder 3, an outer connecting cylinder 4 and a connecting cap 5, and the top of the old hydraulic cylinder 3 is provided with an internal connection cylinder 31, the inner connecting cylinder 31 is provided with a hydraulic oil inlet 32, and the outer connecting cylinder 4 is provided with a hydraulic oil conduit 41. The outer connecting cylinder 4 is sleeved on the outside of the inner connecting cylinder 31, and the connecting cap 5 is threadedly connected to the end of the inner connecting cylinder 31. This connection method is unreliable, and the inner connecting cylinder 31 It is easy to leak oil between the connecting cylinder 31 and the outer connecting cylinder 4 . Cont...
