Abstract
The invention discloses a bottom ring hydraulic nut. The bottom ring hydraulic nut comprises a hydraulic cylinder body, wherein two fast connectors are mounted at an upper end of the hydraulic cylinder body, a piston is mounted in the hydraulic cylinder body in a sliding manner, the hydraulic cylinder body has a U-shaped cross section and is provided with an annular piston, a chamber body is formed in the hydraulic cylinder body, the fast connectors are communicated with the chamber body, screw threads are formed on an outer wall of the piston, and are matched with a locking nut in a screwed manner, and a plurality of countersinks are formed in an outer wall of the locking nut, and are provided with poking rods. The bottom ring hydraulic nut provided in the invention has the advantages of less process flows, simple processing and structure, convenience for operation and maintenance, lower cost and high working pressure while a common working pressure is 150MPa or 220MPa; as the bottom ring hydraulic nut is made from high-strength alloy steel 42CrMo, product safety is improved, and service life is prolonged; as the locking nut is arranged, the piston can be locked at an arbitrary height in a traveling range to ensure safety of an operator and a smaller supporting area; moreover the bottom ring hydraulic nut can be customized as required.
Description
technical field:
The present invention relates to hydraulic nut field, particularly a kind of base ring hydraulic nut.
background technique:
Hydraulic nut is used for the bolt needing frequent dismounting; The pretension of super large bolt; The occasions such as the locking of large-scale workpiece.And hydraulic pressure excessively full connection dismantling device can be made.Diminished shaft or axle sleeve install or remove bearing, normally not only difficulty but also engineering consuming time.Use hydraulic nut. can increase work efficiency, reduce problems.To be hydraulic oil produced by high pressure oil pump input nut the power promoting piston to its principle, meets installation or removal bearing without lifting an eyebrow, not only accurately but also safety.
summary of the invention:
For solving the deficiencies in the prior art, the invention provides a kind of easy to process, simple base ring hydraulic nut of structure.
The technical solution used in the present invention is:
Base ring hydraulic nut, comprise hydraulic cylinder, it is characterized in that: the upper end of described hydraulic cylinder is provided with two rapid pipe joints, piston is slidably fitted with in hydraulic cylinder, be provided with in described hydraulic cylinder that cross section is U-shaped, piston is for annular and is positioned at hydraulic cylinder formation cavity, rapid pipe joint is communicated with this cavity; The outer wall of described piston is provided with screw thread and is screwed with locking nut, and the outer wall of locking nut is provided with some counterbores and is furnished with driving lever.
Described base ring hydraulic nut, is characterized in that: the both sides of the slip surface of described piston all also have annular seal groove, and the inwall of piston and hydraulic cylinder directly seals and is slidably matched.
Compared with prior art, beneficial effect of the present invention is:
Present invention process flow process is few, and processing is simple; Structure is simple, operation, easy to maintenance, low price; Working pressure is high, conventional working pressure 150MPa or 220MPa; Adopt high strength alloy steel 42CrMo to make, improve Security and the life-span of product; With locking nut, arbitrary height within the scope of journey of piston locking being expert at, guarantees the safety of operator; Use supporting surface less; Can according to customer requirement amount body making etc.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is use scheme of installation of the present invention.
embodiment:
Below in conjunction with accompanying drawing, by embodiment, the present invention is described in further detail:
Base ring hydraulic nut, comprise hydraulic cylinder 1, the upper end of hydraulic cylinder 1 is provided with two rapid pipe joints 2, is slidably fitted with piston 3 in hydraulic cylinder 1, be provided with in hydraulic cylinder 1 that cross section is U-shaped, piston 3 is for annular and is positioned at hydraulic cylinder 1 formation cavity, rapid pipe joint 2 is communicated with this cavity; The outer wall of piston 3 is provided with screw thread and is screwed with locking nut 4, the outer wall of locking nut 4 is provided with some counterbores 5 and is furnished with driving lever 6, the both sides of the slip surface of piston 3 all also have annular seal groove 7, and piston 3 directly seals with the inwall of hydraulic cylinder 1 and is slidably matched.
Above-described embodiment is only preferably mode of execution of the present invention, and in addition, the present invention can also have other implementations.It should be noted that, under the prerequisite not departing from the present invention's design, any apparent improvement and modification all should fall within protection scope of the present invention.
