Description
Technical field
The utility model relates to a kind of hydraulic cylinders, specifically with the hydraulic cylinder of degassing function.
Background technique
Hydraulic cylinder is the hydraulic execution that hydraulic energy is changed into mechanical energy, does straight reciprocating motion (or pendulum motion)
Element.Its structure is simple, reliable operation.Deceleration device when realizing reciprocating motion, can be removed from it, and without between transmission
Gap, movement is steady, therefore is used widely in the hydraulic system of various machinery.
Currently, the hydraulic cylinder used in industry includes cylinder body, the oral area of cylinder body is fixed with cover board, has piston in cylinder body,
It has been arranged concentrically piston rod on the corresponding piston one end of cover board, has there is centre bore, one end of piston rod on the corresponding cover board of piston rod
Centre bore across cover board extends, and is in be slidingly sealed shape connection between piston rod and cover board.Hydraulic cylinder is using one section
Air infiltration is had after time, in cylinder body, air will lead to generate in the hydraulic cylinder course of work and creep or vibrate.It is this hydraulic
Oil cylinder cannot be vented, and easily occur creeping or oscillation phenomenon.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of hydraulic cylinder with degassing function, the hydraulic cylinders
It is less prone to and now creeps or oscillation phenomenon.
To solve the above problems, the following technical schemes are provided:
The hydraulic cylinder with degassing function of the utility model includes cylinder body, and the oral area of cylinder body is fixed with cover board, cylinder body
Inside there is piston, piston rod has been arranged concentrically on the corresponding piston one end of cover board, has had centre bore, piston on the corresponding cover board of piston rod
The centre bore that one end of bar passes through cover board extends, and is in be slidingly sealed shape connection between piston rod and cover board.Its main feature is that institute
Stating has threaded hole on the outer peripheral surface of cover board, the bottom hole arranged concentric of threaded hole has connecting hole, and the bore of connecting hole is less than threaded hole
Bore.There is holding screw in the threaded hole, one end of holding screw is taper, and the front of holding screw tapered end, which is located at, to be connected
It connects in hole, and the oral area surrounding of the outer wall of holding screw tapered end and connecting hole offsets.That corresponding section lid of the inner chamber of cylinder block
There is stomata between plate inner plate surface and the bottom hole of connecting hole.
Wherein, be fixed with connecting rod with one heart on the non-tapered end of the holding screw, far from holding screw connecting rod one end from
The oral area of threaded hole extends, and has pulling handle on the overhanging end of connecting rod.
The threaded hole is arranged along the radial direction of cover board.
The above scheme has the following advantages:
Due to having threaded hole, threaded hole on the outer peripheral surface of the cover board of the hydraulic cylinder with degassing function of the utility model
Bottom hole have connecting hole, have holding screw in threaded hole, one end of holding screw is taper, the lower portion of holding screw tapered end
In in connecting hole, there is stomata between that corresponding section lid plate inner plate surface of inner chamber of cylinder block and the bottom hole of connecting hole.When needing to be vented, unscrew
Holding screw, the air in hydraulic cylinder are successively discharged through air passing hole, connecting hole and threaded hole under the action of hydraulic.The liquid
Compressing cylinder is sealed and is vented using the cooperation of holding screw and threaded hole and connecting hole, so as to avoid hydraulic cylinder work
When occur creep or oscillation phenomenon.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the hydraulic cylinder with degassing function of the utility model.
Specific embodiment
The utility model is described in further details below in conjunction with attached drawing.
As shown in Figure 1, the hydraulic cylinder with degassing function of the utility model includes cylinder body 1, the oral area of cylinder body 1 is fixed
There is cover board 8, has piston in cylinder body 1, piston rod 9, the corresponding lid of piston rod 9 have been arranged concentrically on the corresponding piston one end of cover board 8
There is centre bore on plate 8, the centre bore that one end of piston rod 9 passes through cover board 8 extends, and in sliding between piston rod 9 and cover board 8
Seal shape connection.There is threaded hole 2 on the outer peripheral surface of the cover board 8, the bottom hole arranged concentric of threaded hole 2 has connecting hole 6, connecting hole
6 bore is less than the bore of threaded hole 2.There is holding screw 5 in the threaded hole 2, one end of holding screw 5 is taper, tightening
The front of 5 tapered end of screw is located in connecting hole 6, and four phase of oral area of the outer wall of 5 tapered end of holding screw and connecting hole 6
It supports.There is stomata 7 between that corresponding 8 inner plate surface of section lid plate of 1 inner cavity of cylinder body and the bottom hole of connecting hole 6.
It is fixed with connecting rod 3 with one heart on the non-tapered end of the holding screw 5,3 one end of connecting rod far from holding screw 5 is from spiral shell
The oral area of pit 2 extends, and has pulling handle 4 on the overhanging end of connecting rod 3.
Radial direction arrangement of the threaded hole 2 along cover board 8.
When needing to be vented, holding screw 5 is unscrewed, the air in hydraulic cylinder is under the action of hydraulic, successively through air passing hole
7, connecting hole 6 and threaded hole 2 are discharged.The hydraulic cylinder with degassing function of the utility model utilizes holding screw 5 and screw thread
The cooperation in hole 2 and connecting hole 6 is sealed and is vented, and creeping or vibrating for occurring when so as to avoid hydraulic cylinder work shows
As.
