Abstract
The utility model relates to a kind of hydraulic cylinders, specifically with the hydraulic cylinder of pooling feature.It includes cylinder body, and the oral area of cylinder body is fixed with cover board, has piston in cylinder body, cover board has been arranged concentrically drive rod on corresponding piston one end, there is centre bore on the corresponding cover board of drive rod, the centre bore that one end of drive rod passes through cover board extends, and is in be slidingly sealed shape connection between drive rod and cover board.Its main feature is that being arranged concentrically columnar cavity in the piston, plunger is arranged concentrically in cavity, in sliding shape cooperation between plunger and cavity, cavity is interior to be filled with pressure oil, is evenly equipped with axially extending bore on plunger.The one end for passing through piston positioned at the intracorporal drive rod one end of cylinder is extend into cavity, and in shape cooperation is slidingly sealed, drive rod one end in cavity is fixed on plunger for drive rod and piston space.The service life of the hydraulic cylinder is longer.
Description
Technical field
The utility model relates to a kind of hydraulic cylinders, specifically with the hydraulic cylinder of pooling feature.
Background technique
In hydraulic system executive component field, hydraulic cylinder and hydraulic motor occupy irreplaceable position.For straight line
The executive component of movement, hydraulic cylinder are widely used in various industries.
Currently, traditional hydraulic cylinder includes cylinder body, the oral area of cylinder body is fixed with cover board, there is piston, cover board pair in cylinder body
It has been arranged concentrically drive rod on the piston one end answered, has there is centre bore on the corresponding cover board of drive rod, one end of drive rod passes through lid
The centre bore of plate extends, and is in be slidingly sealed shape connection between drive rod and cover board.Hydraulic cylinder at work, drive rod
Extend and retract is controlled by hydraulic system reversal valve.Conventional hydraulic oil cylinder is in the moment of commutation, and hydraulic oil is to piston moment
Impact force it is larger, will lead to piston and generate larger vibration, cause piston and cylinder side wall to generate shock, reduce the use of piston
Service life.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of hydraulic cylinder with pooling feature, the hydraulic cylinder
Service life is longer.
To solve the above problems, the following technical schemes are provided:
The hydraulic cylinder with pooling feature 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, drive rod has been arranged concentrically on the corresponding piston one end of cover board, has had centre bore on the corresponding cover board of drive rod, drives
The centre bore that one end of bar passes through cover board extends, and is in be slidingly sealed shape connection between drive rod and cover board.Its main feature is that institute
It states and has been arranged concentrically columnar cavity in piston, plunger has been arranged concentrically in cavity, it is empty in sliding shape cooperation between plunger and cavity
It is intracavitary to be filled with pressure oil, axially extending bore is evenly equipped on plunger.It stretches the one end for passing through piston positioned at the intracorporal drive rod one end of cylinder
Enter into cavity, in shape cooperation is slidingly sealed, drive rod one end in cavity is fixed on plunger for drive rod and piston space.
Wherein, ring type seal is provided on the inner wall of the centre bore.
The above scheme has the following advantages:
Due to having columnar cavity in the piston of the hydraulic cylinder with pooling feature of the utility model, there is column in cavity
Plug, cavity is interior to be filled with pressure oil, and edge is evenly equipped with axially extending bore on plunger, passes through piston positioned at the intracorporal drive rod one end of cylinder
One end is extend into cavity, and drive rod one end in cavity is fixed on plunger.When hydraulic cylinder commutation, hydraulic oil is pushed away
Piston movement, piston and plunger generate relative motion, the pressure oil in extrusion piston cavity, and pressure oil reacts on piston
On, it offsets hydraulic oil and is avoided by piston vibration and is hit with cylinder side wall so that piston will not generate vibration for the impact force of piston
The problem of hitting extends the service life of piston.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the hydraulic cylinder with pooling feature 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 pooling feature of the utility model includes cylinder body 1, the oral area of cylinder body 1 is fixed
There is cover board 8, there is piston 2 in cylinder body 1, cover board 8 has been arranged concentrically drive rod 7 on corresponding 2 one end of piston, and drive rod 7 is corresponding
There is centre bore on cover board 8, the centre bore that one end of drive rod 7 passes through cover board 8 extends, and in cunning between drive rod 7 and cover board 8
The connection of dynamic sealing shape.Be arranged concentrically columnar cavity 3 in the piston 2, be arranged concentrically plunger 5 in cavity 3, plunger 5 with
In sliding shape cooperation between cavity 3, cavity 3 is interior to be filled with pressure oil 4, is evenly equipped with axially extending bore 6 on plunger 5.In cylinder body 1
One end that 7 one end of drive rod passes through piston 2 is extend into cavity 3, in shape cooperation is slidingly sealed between drive rod 7 and piston 2, is located at
7 one end of drive rod in cavity 3 is fixed on plunger 5.Ring type seal 9 is provided on the inner wall of the centre bore.
In use, hydraulic oil pushes piston 2 to move when hydraulic cylinder commutation, piston 2 and plunger 5 generate relative motion,
Pressure oil 4 in 2 cavity 3 of extrusion piston, pressure oil 4 react on piston 2, offset hydraulic oil to the impact force of piston 2, make
Piston 2 will not generate vibration, avoid piston 2 and vibrate the problem of with 1 side wall impact of cylinder body, extend the use of piston 2
Service life.
