Abstract
The invention discloses a kind of hydraulic cylinder, including cylinder body, piston rod, piston, the first end cap and the second end cap, first end cap and the second end cap are separately fixed at the opposite end of cylinder body, one end of piston rod is in cylinder body, the other end, which runs through after the first end cap, to be stretched out on the outside of cylinder body, and piston is set on piston rod, and runner is provided with the outside of cylinder body, during work, cooling water passes through the runner.By the way that provided with the first end cap and the second end cap, the installation of piston rod and piston, ease of assembly can be facilitated；Runner is provided with the outside of cylinder body so that hydraulic cylinder operationally, take away in time, it is ensured that the normal work of hydraulic cylinder by the heat that the cooling water of flowing can produce work in runner.
Description
Technical field
The invention belongs to a kind of machinery equipment field, more particularly, to a kind of hydraulic cylinder.
Background technology
Hydraulic cylinder is that hydraulic energy is changed into mechanical energy, does the hydraulic actuator of straight reciprocating motion.Its is simple in construction,
Reliable operation；Realized with it during reciprocating motion, can remove deceleration device from, and without drive gap, stable movement, therefore
It is used widely in various mechanical hydraulic systems.But existing hydraulic cylinder much installs inconvenience, and in long-term work
Easily there is superheating phenomenon in journey, influence its work quality.
The content of the invention
It is an object of the invention to provide a kind of hydraulic cylinder, at least one in above mentioned problem can solve the problem that.
According to an aspect of the invention, there is provided a kind of hydraulic cylinder, including cylinder body, piston rod, piston, the first end cap and
Second end cap, the first end cap and the second end cap are separately fixed at the opposite end of cylinder body, and one end of piston rod is in cylinder body, separately
One end, which is run through after the first end cap, to be stretched out on the outside of cylinder body, and piston is set on piston rod, and runner is provided with the outside of cylinder body, cold during work
But water passes through the runner.
The beneficial effects of the invention are as follows：By the way that piston rod and piston provided with the first end cap and the second end cap, can be facilitated
Install, ease of assembly；Runner is provided with the outside of cylinder body so that operationally, the cooling water of flowing can be by work in runner for hydraulic cylinder
The heat for making to produce is taken away in time, it is ensured that the normal work of hydraulic cylinder.
In some embodiments, sealing ring is provided between piston and cylinder body, sealing ring on the inside of cylinder body with being in close contact.By
This, it is possible to achieve the sealing of hydraulic oil.
In some embodiments, hydraulic cylinder also includes bolster, and bolster is fixed on the inside of the second end cap, with piston rod
It is correspondingly arranged.Thus, it is possible to avoid piston rod from directly impacting the second end cap, and can with damper piston bar end point of travel movement
Speed.
In some embodiments, bolster is elastic component.As a result, bolster reaches good buffering effect.
In some embodiments, it is equipped with sealing ring at the first end cap, the second end cap and cylinder body sealing.Thereby it is ensured that
The sealing of hydraulic oil in cylinder body.
Brief description of the drawings
Fig. 1 is the structural representation of the hydraulic cylinder of the present invention.
Embodiment
The invention will now be described in further detail with reference to the accompanying drawings.
Reference picture 1：The hydraulic cylinder of the present invention, including cylinder body 1, piston rod 2, piston 3, the first end cap 4 and the second end cap 5,
First end cap 4 and the second end cap 5 are separately fixed at the opposite end of cylinder body 1, and one end of piston rod 2 is in cylinder body 1, the other end
The outside of cylinder body 1 is stretched out after the first end cap 4, piston 3 is set on piston rod 2, the outside of cylinder body 1 is provided with runner 6, during work,
Cooling water passes through the runner 6, and runner 6 can be around the periphery for being located at cylinder body 1.
Therefore, when hydraulic cylinder is started working, the cooling water of flowing is passed through in runner 6, so that, cooling water is in flow process
In, the heat in cylinder body 1 is taken away, it is to avoid temperature is too high in cylinder body 1, it is ensured that the normal work of hydraulic cylinder.
The hydraulic cylinder is in assembling, and after piston 3 is set on piston rod 2, piston rod 2 is reloaded into cylinder body 1；Then pacify
Fill the first end cap 4.First end cap 4 is bolted on cylinder body 1.
Sealing ring 7 is provided between piston 3 and cylinder body 1, sealing ring 7 is in close contact with the inner side of cylinder body 1.
Hydraulic cylinder also includes bolster 8, and bolster 8 is fixed on the inner side of the second end cap 5, is correspondingly arranged with piston rod 2, that is, lives
When stopper rod 2 is moved to end, the end thereof contacts of piston rod 2 to bolster 8.Wherein, bolster 8 is elastic component, can be compression
Spring or rubber part.Provided with bolster 8 piston rod 2 can be avoided to strike the second end cap 5, prevented to cylinder body 1
Impulsive force is excessive.
First end cap 4, the second end cap 5 effectively prevent the hydraulic oil in cylinder body 1 with being equipped with sealing ring 7 at the sealing of cylinder body 1
Leak.
Above-described is only the preferred embodiment of the present invention, it is noted that for one of ordinary skill in the art
For, without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the present invention
Protection domain.
