Abstract
The utility model discloses a hydraulic cylinder belongs to hydraulic equipment technical field. Hydraulic cylinder includes cylinder body, piston, piston rod, high pressure spring, U -type sealing ring, O type sealing washer, radiation shield casing. The utility model discloses simple structure can play the effect of buffering, has good sealing performance and heat -proof quality again, can work steadily.
Description
Technical field
The utility model relates to hydraulic cylinder, belongs to technical field of hydraulic equipment.
Background technology
During hydraulic cylinder high speed operation, there is factors can affect the job stability of cylinder device, such as (1) if piston is direct
Bump against with the end cap of hydraulic cylinder, end cap can be damaged, and bigger shock loading can be produced under the effect of inertia force and hydraulic coupling,
Affect the stability of hydraulic system；(2) quality of hydraulic cylinder sealing performance directly affects the service behaviour of hydraulic cylinder, affects whole
The normal use of equipment, therefore, the sealing problem of hydraulic cylinder it is critical that；(3) hydraulic cylinder can produce in the course of the work
Substantial amounts of heat, affects the service life of hydraulic cylinder.
Utility model content
For overcoming drawbacks described above, the utility model aims to provide a kind of hydraulic cylinder, including cylinder body, piston, piston rod, bomb
Spring, U-shaped sealing ring, O RunddichtringO, collet；The periphery of described piston is provided with sealing ring mounting groove, and U-shaped sealing ring is pacified
Being contained in sealing ring mounting groove, O RunddichtringO is arranged between inboard wall of cylinder block and U-shaped sealing ring；Described high pressure spring is arranged on
Cylinder base；Described collet is located at cylinder body periphery, has cavity, described cavity to be provided with compressed-air actuated between collet and cylinder body
Import and export.
Described high pressure spring is arranged on cylinder base by axle check ring.
Described collet uses heat-barrier material.
The utility model also provides for a kind of hydraulic system, containing described hydraulic cylinder.
The utility model, by installing high pressure spring, simple in construction in cylinder base, can play the effect of buffering, will not give again
Hydraulic cylinder brings big weight load, it is provided that the stability of hydraulic cylinder；By being applied in combination U-shaped sealing ring, O RunddichtringO,
Realize good sealing；By arranging collet, utilize compressed air to take away the heat of cylinder surface, reach the mesh dispelled the heat in time
, thus improve the service life of hydraulic cylinder.
Accompanying drawing explanation
The structural representation of a kind of embodiment of Fig. 1 the utility model；1, cylinder body, 2, piston, 3, piston rod, 4, high pressure
Spring, 5, U-shaped sealing ring, 6, O RunddichtringO, 7, collet, 8, air inlet, 9, gas outlet.
Detailed description of the invention
As it is shown in figure 1, a kind of hydraulic cylinder, including cylinder body 1, piston 2, piston rod 3, high pressure spring 4, U-shaped sealing
Circle 5, O RunddichtringO 6, collet 7, air inlet 8, gas outlet 9.
Cylinder base is mounted with high pressure spring 4 by axle check ring, when piston 2 moves to the position close to cylinder base,
Touching high pressure spring 4, movement velocity slows down, and so can play the effect of buffering, will not bring big weight to hydraulic cylinder again
Amount burden, and easy for installation.
By being applied in combination U-shaped sealing ring 5, O RunddichtringO 6, during hydraulic cylinder, U-shaped sealing ring 5 is subject to
Pressure pass to O RunddichtringO 6 further, maximum pressure point is transformed into sealing ring edge by O RunddichtringO 6, it is achieved good
Good sealing.
By arranging collet 7, in the cavity between collet 7 and cylinder body 1, constantly it is passed through the compressed air of flowing, soon
Speed belt walks the heat that piston movement process produces, and reaches the purpose dispelled the heat in time, improves the performance of hydraulic cylinder.
Although the utility model is open the most as above with preferred embodiment, but it is not limited to the utility model, any is familiar with this
The people of technology, without departing from spirit and scope of the present utility model, can do various changes and modification, and therefore this practicality is new
The protection domain of type should be with being as the criterion that claims are defined.
Claims (3)
1. a hydraulic cylinder, it is characterised in that include cylinder body, piston, piston rod, high pressure spring, U-shaped sealing ring, O RunddichtringO, collet；The periphery of described piston is provided with sealing ring mounting groove, and U-shaped sealing ring is arranged in sealing ring mounting groove, and O RunddichtringO is arranged between inboard wall of cylinder block and U-shaped sealing ring；Described high pressure spring is arranged on cylinder base；Described collet is located at cylinder body periphery, has cavity, described cavity to be provided with compressed-air actuated import and export between collet and cylinder body.
