Abstract
The utility model relates to a kind of hydraulic system components, specifically with the hydraulic cylinder of pooling feature.It includes cylinder body, there is piston in cylinder body, and in shape cooperation is slidingly sealed between the side wall and inboard wall of cylinder block of piston, there is piston rod in one end of piston, and the other end has end cap on corresponding cylinder body one end, there is the hydraulic fluid port for being connected with hydraulic system on end cap.Its main feature is that having buffer plunger on that piston end surface of proximal cover, there is the blind hole for accommodating buffer plunger on that corresponding end cap of buffer plunger, and the internal diameter of the blind hole is greater than the outer diameter of buffer plunger；The hydraulic fluid port is located at the position being connected on the side wall of blind hole with bottom.For the hydraulic cylinder when driving the biggish component of quality reciprocating, piston and the mechanical collision that cylinder cap occurs are slight, and the impact of generation and noise are smaller, and service life is longer.
Description
Technical field
The utility model relates to a kind of hydraulic system components, specifically with the hydraulic cylinder of pooling feature.
Background technique
It is both known about in hydraulic drive row, there is hydraulic cylinder in hydraulic system.Currently, the hydraulic cylinder used in industry
Including cylinder body, there is piston in cylinder body, in shape cooperation is slidingly sealed between the side wall and inboard wall of cylinder block of piston, there is piston in one end of piston
Bar, the other end have end cap on corresponding cylinder body one end, there is the hydraulic fluid port for being connected with hydraulic system on end cap.This hydraulic cylinder
When driving the biggish component of quality reciprocating, due to the effect of inertia, piston can occur serious machinery with end cap and touch
It hits, greater impact power and noise is generated, so that the service life of oil cylinder is shorter.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of hydraulic cylinder with pooling feature, the hydraulic cylinders
When driving the biggish component of quality reciprocating, piston and the mechanical collision that cylinder cap occurs are slight, the impact of generation and make an uproar
Sound is smaller, and 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, there is piston in cylinder body, the side wall of piston with
In shape cooperation is slidingly sealed between inboard wall of cylinder block, there is piston rod in one end of piston, and the other end has end cap on corresponding cylinder body one end, end
Cover the hydraulic fluid port for being connected with hydraulic system.Its main feature is that having buffer plunger on that piston end surface of proximal cover, delay
The blind hole having on that corresponding end cap of plunger for accommodating buffer plunger is rushed, and the internal diameter of the blind hole is greater than the outer of buffer plunger
Diameter；The hydraulic fluid port is located at the position being connected on the side wall of blind hole with bottom.
Wherein, the buffer plunger is in a circular table shape, and its that one end being relatively large in diameter is connected with piston.
The above scheme has the following advantages:
Due to having on that piston end surface of the not piston rod of the hydraulic cylinder with pooling feature of the utility model
Buffer plunger has the blind hole for accommodating buffer plunger on that corresponding end cap of buffer plunger, and the internal diameter of the blind hole is greater than
The outer diameter of buffer plunger, hydraulic fluid port are located at the position being connected on the side wall of blind hole with bottom.When piston motion is to making buffer plunger
When entering in blind hole, the hydraulic oil between piston and end cap is only capable of entering hydraulic fluid port in the gap between buffer plunger and blind hole
In, so that moment reduces oil pump capacity, so that most of hydraulic oil remains in the cylinder body between piston and end cap.Therefore, piston
The reaction force being subject to increases, so that the mechanical collision of piston and end cap becomes slight, the impact force and noise of generation are smaller, from
And improve the service life of oil cylinder.
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 detail below in conjunction with attached drawing.
As shown in Figure 1, the hydraulic cylinder with pooling feature of the utility model of the utility model includes cylinder body 2, cylinder
There is piston 3 in body 2, is in be slidingly sealed shape cooperation between 2 inner wall of side wall and cylinder body of piston 3, there is piston rod 1 in one end of piston 3, separately
There is end cap 5 in one end on corresponding 2 one end of cylinder body, there is the hydraulic fluid port 6 for being connected with hydraulic system on end cap 5.By that of proximal cover 5
There is buffer plunger 4 on a 3 end face of piston, there is the blind hole for accommodating buffer plunger 4 on that the corresponding end cap 5 of buffer plunger 4
7, and the internal diameter of the blind hole 7 is greater than the outer diameter of buffer plunger 4；The hydraulic fluid port 6 is located at the position being connected on the side wall of blind hole 7 with bottom
Set place.
In order to further increase buffering effect, the buffer plunger 4 is in a circular table shape, and its that one end for being relatively large in diameter and work
Plug 3 is connected.
In use, the hydraulic oil when piston 3, which moves to, enters buffer plunger 4 in blind hole 7, between piston 3 and end cap 5
It is only capable of entering in hydraulic fluid port 6 in the gap between buffer plunger 4 and blind hole 7, so that moment reduces oil pump capacity, so that most of
Hydraulic oil remains in the cylinder body 2 between piston 3 and end cap 5.Therefore, piston 3 is subject to reaction force increases so that piston 3 with
The mechanical collision of end cap 5 becomes slight.
