Description
Technical field
It the utility model is related to technical field of hydraulic equipment, and in particular to a kind of hydraulic pressure releases equipment.
Background technology
Hydraulic cylinder is one of most important executive component in Hydraulic Power Transmission System, and hydraulic energy is converted into mechanical energy, makes machine
Tool equipment realizes straight reciprocating motion or gyration.Fabricate horizontal raising, the development need of Grand Equipments, industry hair
The change of exhibition hysteresis situation causes hydraulic technique turns into realize that Automation of Manufacturing Process, raising work production etc. are essential invariably
Important means, hydraulic cylinder has small volume, light weight, reliable operation, flexible, the easy to control, output loads of configuration are big, use
Repair the advantages that easy, be widely used in service load is big, condition of work is severe engineering machinery, mining machinery, Shipping,
The industries such as petrochemical industry, specialized robot.With industrial production, the fast development of automated manufacturing.
During hydraulic cylinder high speed operation, there is the job stability that factors can influence cylinder device, when piston run to
During stroke terminal, violent mechanical collision is tended to occur.In addition, the unexpected stop motion of piston also usually causes pipeline that water attack occurs
Phenomenon, produce greatly impact and noise.Above mechanical shock not only influences the service behaviour of plant equipment, and can damage liquid
The other elements of cylinder pressure and hydraulic system, there is very big danger, influence the stability of hydraulic system.It is this to mitigate or preventing
Impact shock, have in the prior art and buffer unit is set inside hydraulic cylinder, a certain degree of cushioning effect can be played, but deposit
Inadequate stable and continuous is being buffered, the problem of cushion effect is too small.
The content of the invention
In view of the shortcomings of the prior art, a kind of hydraulic pressure release equipment of the utility model offer, achievable mitigation mechanical shock,
The purpose of stable buffering and increase cushion effect.
What the technical solution of the utility model was realized in：A kind of hydraulic pressure releases equipment, including cylinder body, is arranged on cylinder body
Interior piston rod, it is arranged on the piston of piston rod one end and is arranged on the cylinder cap of cylinder ends, one end of described piston rod is opened
Provided with cavity is slided, slide in cavity and be arranged with sliding bar, compression spring, one end of sliding bar and piston are arranged with sliding bar
Connection, the end of piston is embedded with the first permanent magnet, is provided with cylinder cap and opposite polarity second permanent magnet of the first permanent magnet.
The end of described sliding bar is provided with cylinder projection, the raised diameter of cylinder and the diameter phase for sliding cavity
Together, the diameter of sliding bar is less than the raised diameter of cylinder, and the length of sliding bar is less than the length for sliding cavity.
Hydraulic fluid port is offered on the outer wall of described cylinder cap.
The utility model has following good effect：The setting of compression spring, the first permanent magnet and the second permanent magnet can
Realize piston to cylinder cap move when resistance increase, speed reduce, cushioning effect is played, using the first permanent magnet and the second permanent magnetism
Iron can replace traditional rubber buffer, and solution is easy to aging, impact resistance is weak, replacing is frequent and ineffective problem,
When can effectively avoid that piston movement is to extreme position in hydraulic cylinder, the phenomenon of piston slap cylinder cap is avoided.
Brief description of the drawings
Fig. 1 is cross section structure diagram of the present utility model.
Embodiment
As shown in figure 1, the utility model includes cylinder body 1, the piston rod 2 being arranged in cylinder body 1, is arranged on piston rod 2 one
The piston 3 at end and the cylinder cap 4 for being arranged on the end of cylinder body 1, one end of described piston rod 2, which offers, slides cavity 5, slides cavity
Sliding bar 6 is arranged with 5, compression spring 7 is arranged with sliding bar 6, one end of sliding bar 6 is connected with piston 3, the end of piston 3
Portion is embedded with the first permanent magnet 8, is provided with cylinder cap 4 and 8 opposite polarity second permanent magnet 9 of the first permanent magnet.
The end of sliding bar 6 is provided with cylinder projection, and the raised diameter of cylinder is identical with the diameter for sliding cavity 5, sliding
The diameter of lever 6 is less than the raised diameter of cylinder, and the length of sliding bar 6 is less than the length for sliding cavity 5.The outer wall of cylinder cap 4
On offer hydraulic fluid port 10.The setting of compression spring 7, the first permanent magnet 8 and the second permanent magnet 9 can be achieved piston 3 and be moved to cylinder cap 4
When resistance increase, speed reduce, play cushioning effect, traditional rubber can be replaced using the first permanent magnet 8 and the second permanent magnet 9
Glue cushion pad, solution is easy to aging, impact resistance is weak, replacing is frequent and ineffective problem, can effectively avoid hydraulic cylinder
When middle piston 3 moves to extreme position, piston 3 is avoided to hit the phenomenon of cylinder cap 4.
Operation principle is as follows：When hydraulic pressure releases equipment work, piston 3 moves to cylinder cap 4, to be moved to the first permanent magnet
8 and second permanent magnet 9 it is close when, the mutually exclusive power of acting of magnet polarities, piston 3 continues to move to, and sliding bar 6 is empty to sliding
The direction of chamber 5 is moved, and then acts on compression spring 7, and the reaction force of compression spring 7 plays cushioning effect, realizes that buffering is continuous
Phenomenon that is steady and effectively avoiding the shock cylinder cap 4 of piston 3.
