Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of hydraulic nuts, in particular to a hydraulic nut with an anti-slip structure. 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. Installing or removing bearings on tapered shafts or sleeves is often a difficult and time-consuming task. Using hydraulic nuts can improve efficiency and reduce these challenges. The principle is that hydraulic oil, pumped into the nut by a high-pressure pump, generates a piston-pushing force, enabling bearing installation or removal—effortlessly, accurately, and safely.
[0003] In the prior art, the fixing piece at the bottom of the hydraulic nut lacks an anti-slip structure when in use, so it is easy to slide during fixation, affecting the stability of the device during use. Therefore, a hydraulic nut with an anti-slip structure is proposed to solve the above problem. Utility Model Content
