Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic nuts, in particular to a nut with a hydraulic resetter. Background Art

[0002] Hydraulic nuts are used for bolts that require frequent assembly and disassembly, pre-tightening oversized bolts, and locking large workpieces. They can also serve as hydraulic interference fit tools for assembly and disassembly. Installing and removing bearings on tapered shafts and sleeves is often a difficult and time-consuming task, but using hydraulic nuts can improve work efficiency. Existing nuts with hydraulic returners, when filled through the oil pipe, can wear the returner and nut due to tiny particles and impurities in the hydraulic oil. Furthermore, hydraulic oil leakage can occur after filling, resulting in certain shortcomings in these devices. Utility Model Content

[0015] The utility model has the following beneficial effects:

[0016] 1. In the utility model, the slide rod is inserted into the slide groove to drive the filter plate to be connected in the cavity, so that the hydraulic oil is filtered out of the internal particles and impurities and then injected into the oil filling pipe, thereby avoiding wear on the hydraulic nut with the resetter.

[0017] 2. In the present invention, the threaded rod passes through the through hole and drives the baffle cover to close at the end of the oil filling pipe where the oil enters, thereby preventing the hydraulic oil from leaking out of the oil filling pipe. BRIEF DESCRIPTION OF THE DRAWINGS
