Description
technical field:
The utility model relates to hydraulic nut field, particularly a kind of HN type hydraulic nut.
background technique:
Hydraulic nut is used for the occasion such as bolt, the pretension of super large bolt, the locking of large-scale workpiece needing frequent dismounting.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.
model utility content:
For solving the deficiencies in the prior art, the utility model provides a kind of easy to process, structure simple HN type hydraulic nut.
The technical solution adopted in the utility model is:
HN type hydraulic nut, comprise hydraulic cylinder, it is characterized in that: described hydraulic cylinder is flat annular, and its inwall is provided with screw thread, hydraulic cylinder upper wall has circular groove as cavity and slides up and down and be provided with annular piston, described hydraulic cylinder sidewall has mounting hole and pulling hole, and the inner bottom part of mounting hole is communicated to the bottom of circular groove, is provided with screw thread and is provided with rapid pipe joint in mounting hole.
Described HN type 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, the beneficial effects of the utility model are:
The utility model technological process is few, and processing is simple; Structure is simple, simple to operate, easy to maintenance, low price; Working pressure is high, and usage space is little; Adopt high strength alloy steel 42CrMo to make, improve Security and the life-span of product; Can according to customer requirement amount body making etc.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation;
Fig. 2 is use scheme of installation of the present utility model.
embodiment:
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail:
HN type hydraulic nut, comprise hydraulic cylinder 1, hydraulic cylinder 1 is flat annular, and its inwall is provided with screw thread, hydraulic cylinder 1 upper wall has circular groove 2 as cavity and slides up and down and be provided with annular piston 3, hydraulic cylinder 1 sidewall has mounting hole and pulling hole 4, the inner bottom part of mounting hole is communicated to the bottom of circular groove 3, be provided with screw thread in mounting hole and rapid pipe joint 5 is installed, the both sides of the slip surface of piston 3 all also have annular seal groove 6, 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 utility model, and in addition, the utility model can also have other implementations.It should be noted that, under the prerequisite not departing from the utility model design, any apparent improvement and modification all should fall within protection domain of the present utility model.
