Description
Technical field
The invention belongs to mechanical equipment technical fields, are related to a kind of dust-extraction unit, more particularly, to a kind of cylinder piston rod
Dust-extraction unit.
Background technique
Hydraulic cylinder is a kind of using very extensive industrial automation arrangement, and common hydraulic cylinder is generally mostly to be oriented to
Set is embedded in cylinder body, and piston rod is then equipped in guide sleeve.Well known oil cylinder is equipped with close between piston rod and guide sleeve
Seal is carried out dust-proof by sealing ring.But the implementation result of this structure is undesirable, especially the more severe feelings of working environment
It under condition, will appear many dirts on the piston rod of oil cylinder, seriously affect the normal work of oil cylinder, the service life of oil cylinder is caused to contract
It is short.
Of the existing technology in order to solve the problems, such as, people have carried out long-term exploration, propose miscellaneous solution
Scheme.Chinese patent literature disclose a kind of oil cylinder of big arm of digger [application number: 200920023835.3], including piston rod,
Cylinder barrel, oil pipe, piston and cylinder bottom, which is characterized in that be equipped with guide sleeve in one end of cylinder barrel, the other end is equipped with cylinder bottom, piston rod
It is linked in cylinder barrel by guide sleeve, is equipped with piston in one end of piston rod, is linked in work at the side of piston place adjacent thereto
There is a floating buffer set at the long end of stopper rod, and floating buffer set is that an inner wall is that there are three oblique flat structures for cylindrical, outer wall belt.
Above scheme improves the prior art to a certain extent, extends the service life of oil cylinder.But the program
For dustband in dust-proof effect, effect is undesirable, and in the working repeatedly of oil cylinder, dust or dirt can glue on the piston rod, leads to
Moving back and forth for piston rod is crossed, dust or dirt are brought into plunger shaft, are caused the oil of oil cylinder contaminated, are being destroyed oil cylinder just
Often work, oil cylinder are also possible that oil leak, lead to the reduced service life of oil cylinder.
Summary of the invention
Regarding the issue above, the present invention provides a kind of design is reasonable, structure is simple, easy for installation, dust-proof effect
Fruit is good, good airproof performance, the operation is stable, the dust-extraction unit of cylinder piston rod with long service life.
In order to achieve the above objectives, present invention employs following technical proposals: the dust-extraction unit of this cylinder piston rod, and setting exists
Between guide sleeve and piston rod, which is characterized in that the present apparatus includes the dust scraper being arranged on guide sleeve and retaining ring, described
The top of dust scraper is arranged in retaining ring.
Due to being provided with dust scraper, after dust or dirt can glue on the piston rod, piston rod bounces back to most from longest end
It, at this moment can be by the dust or soil release on piston rod by dust scraper when at short end；It is by retaining ring that dust scraper is firm
Fixation, not only good dedusting effect, but also the big step of job stability of oil cylinder improves, and extends the service life of oil cylinder.
In the dust-extraction unit of above-mentioned cylinder piston rod, washer is equipped with below the dust scraper.Sealing effect is good.
In the dust-extraction unit of above-mentioned cylinder piston rod, support sleeve is equipped between the dust scraper and washer.
In the dust-extraction unit of above-mentioned cylinder piston rod, the dust scraper is in a ring.
In the dust-extraction unit of above-mentioned cylinder piston rod, the washer is in U-shape.It is easy for installation.
Compared with prior art, the advantages of dust-extraction unit of this cylinder piston rod is: 1, design is reasonable, structure is simple
It is single.2, due to being provided with dust scraper, after dust or dirt can glue on the piston rod, piston rod bounces back to most short end from longest end
It, at this moment can be by the dust or soil release on piston rod by dust scraper when place；Consolidated by retaining ring by dust scraper is firm
Fixed, not only good dedusting effect, but also the big step raising of job stability of oil cylinder extends the service life of oil cylinder.3, sealing effect
Fruit is good.4, easy for installation.
Detailed description of the invention
Fig. 1 is structural schematic diagram provided by the invention.
In figure, guide sleeve 1, piston rod 2, dust scraper 3, retaining ring 4, washer 6, support sleeve 5.
Specific embodiment
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, the dust-extraction unit of this cylinder piston rod, is arranged between guide sleeve 1 and piston rod 2, present apparatus packet
The dust scraper 3 being arranged on guide sleeve 1 and retaining ring 4 are included, the top of dust scraper 3 is arranged in retaining ring 4.Preferably,
Here dust scraper 3 is in a ring.
Specifically, being equipped with washer 6 below dust scraper 3.Support sleeve 5 is equipped between dust scraper 3 and washer 6.As excellent
Scheme is selected, washer 6 here is in U-shape.
In the present embodiment, due to being provided with dust scraper 3, after dust or dirt can be sticked on piston rod 2, piston rod 2
It, at this moment can be by the dust or soil release on piston rod 2 by dust scraper 3 when bouncing back to from most short end from longest end；Pass through
The fixation that dust scraper 3 is firm of retaining ring 4, not only good dedusting effect, but also the big step raising of job stability of oil cylinder, extends
The service life of oil cylinder.
Specific embodiment described herein is only an example for the spirit of the invention.The neck of technology belonging to the present invention
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
Although the arts such as guide sleeve 1, piston rod 2, dust scraper 3, retaining ring 4, washer 6, support sleeve 5 are used more herein
Language, but it does not exclude the possibility of using other terms.The use of these items is only for be more convenient to describe and explain this
The essence of invention；Being construed as any additional limitation is disagreed with spirit of that invention.
