The working principle of the utility model is as follows:
In the design, for cylinder assembly: cylinder body barrel shell is made of lower cylinders 102 and upper cylinder 103；Upper cylinder
103 bottom and top are correspondingly arranged on lead ring platform 106 and lower lead ring platform 105；The upper lead ring platform 106 and lower lead ring platform
Guide channel is formed between 105.Part cylinder body of the plunger rod between cylinder assembly, is finished, lead ring platform 106 in setting
With lower lead ring platform 105, two boss play the control that flow is carried out to plunger rod guiding role and control-rod.On plunger rod top
It is mounted directly O-ring seal to leak outside for Seal Oil, there is certain working depth in the region between two boss, in use process
It will form an oil ring after middle addition oil, play the role of a lubrication to plunger rod.
Assembly for plunger is directed in the design: plunger rod processing is simple, and intensity is more preferable, is unlikely to deform, and is mainly processed as plunger
The roughness requirements of bar outside diameter and outer circle can preferably be cooperated with cylinder body, and upper and lower one, disk is played fixed function,
The following hole risen with control-rod control oil stream amount size, overall structure is simple, and use intensity is more preferable.
The design's the utility model has the advantages that
(1) structural strengthening of cylinder body, processing technology is simple, about the oil sealing problem of cylinder body and plunger, directly again on cylinder body
Step is processed, and O-ring seal is added, installation metallic packing ring existing compared with market reduces processing cumulative errors, cost and peace
Equipped with being decreased obviously.
(2) plunger rod structural strengthening, processing technology is simple, and hydraulic bjuffer is there are after impact test on existing market, column
Stopper rod does not sink, and stuck or plunger rod does not spring back stuck problem after sinking, and main cause is exactly that the intensity of plunger not enough causes
Deformation, cannot carry out piston motion with control-rod or cylinder body well, now apply for that structure effectively avoids such case
Occur, mainly cylinder body itself has guiding role, and it is determined that the performance of product, there is no in assembling process when installation
Error is mobile.
A kind of hydraulic damping device described in the utility model, it forms guiding using two boss are arranged in cylinder body
Effect, and O-ring seals, which are added, in cylinder body internal upper part prevents Seal Oil from leaking outside, it, which has, greatly subtracts producing and install
Installation cost is processed less, greatlys improve the working efficiency of buffer, and solves the problems, such as that plunger rod is easily stuck.
The above description is only a preferred embodiment of the present invention, therefore all according to described in the utility model patent application range
The equivalent change or modification done of structure, feature and principle, be included in the scope of the utility model patent application.
