Abstract
The invention discloses an oil cylinder capable of passing oil by a piston rod, and aims to provide the oil cylinder capable of passing oil by the piston rod; the oil cylinder disclosed by the invention comprises a piston rod, and is characterized in that an oil channel is formed in the piston rod; one end of the oil channel is communicated with an oil opening; the other end of the oil channel is communicated with an oil cavity; the piston rod is a hollow pipe; and an oil channel pipe is welded in the piston rod. According to the invention, the oil cylinder is mainly applied to oil cylinders with a piston rod fixing method and cylinder body moving/working methods.
Description
Technical field
The present invention relates to a kind of logical oil cylinder, relate in particular to the logical oil cylinder of a kind of piston rod.
Background technique
At present, oil cylinder adopts all that cylinder body is fixed, the working method of piston rod movement, and work fluid is from being positioned at the interface turnover on the cylinder body.Some equipment because of structure need adopt that piston rod is fixed, during the working method of movement of cylinder block, the oil pipe that is connected on the cylinder body interface will influence the oil cylinder regular event.Even adopt the flexible pipe Placement; Consider one section length in reserve in order to satisfy oil cylinder movement travel flexible pipe needs; When the working stroke of oil cylinder is big, need occupy for satisfying flexible pipe that stroke reserves that this will influence the physical dimension of equipment greatly than large space, and the folding and unfolding action of flexible pipe can cause the flexible pipe excessive wear and influence working life in the movement of cylinder block process; It is accidents caused that improper wrapping phenomena more likely takes place, and these have all greatly influenced the application of movement of cylinder block form oil cylinder.
Summary of the invention
The object of the present invention is to provide a kind of piston rod to lead to oil cylinder, to overcome above-mentioned deficiency.
For realizing above-mentioned purpose, technical solution of the present invention is: a kind of piston rod leads to oil cylinder, comprises piston rod; It is characterized in that: in the described piston rod 1; Have oil duct 2,2 ', an end of oil duct 2 is communicated with hydraulic fluid port 3, the other end is communicated with oil pocket 4; Oil duct 2 ' an end and hydraulic fluid port 3 ' be communicated with, the other end and oil pocket 4 ' be communicated with.
Described piston rod 1 is a hollow tubular, in it, is welded with oil duct pipe 14.
The invention has the beneficial effects as follows: pass in and out oily mode through oil duct is set in the oil cylinder piston bar, the external oil pipe constrained motion problem of oil cylinder has increased the oil cylinder application area when having solved movement of cylinder block.Adopt the processing technology of soldering oil deferent in the box type piston bar of the present invention, greatly reduce, reduced processing cost than the inner oil duct difficulty of processing of long-term job stopper rod.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation of piston rod of the present invention.
Fig. 3 is an embodiment's of a piston rod of the present invention structural representation.
Among the figure: 1-piston rod, 2,2 '-oil duct, 3,3 '-hydraulic fluid port, 4,4 '-oil pocket; 5-piston rod flange, 6-dust ring, 7-rod seal part, 8-cylinder body front cover; 9-cylinder body, 10-piston, 11-piston seal; 12-locking nut, 13-rear end of the cylinder block lid, 14-oil duct pipe.
Embodiment
Below in conjunction with accompanying drawing the present invention and embodiment thereof are done further explain.
Referring to accompanying drawing 1-3, the present invention includes piston rod, it is characterized in that: in the described piston rod; Have oil duct 2,2 ', an end of oil duct 2 is communicated with hydraulic fluid port 3, the other end is communicated with oil pocket 4; Oil duct 2 ' an end and hydraulic fluid port 3 ' be communicated with, the other end and oil pocket 4 ' be communicated with.
Described piston rod 1 is a hollow tubular, in it, is welded with oil duct pipe 14.
Piston rod flange 5 passes through bolton in the piston rod end; The piston rod flange is fixed during installation; The external oil pipe of oil cylinder be connected to hydraulic fluid port 3,3 ' on; Hydraulic fluid port 3,3 on piston rod 1 inner two oil ducts 2,2 ' respectively and the piston rod flange ' be communicated with, one is communicated with piston left side oil pocket 4, another be communicated with piston right side oil pocket 4 '.During work, piston rod is fixed, the cylinder body to-and-fro motion.For the short stroke oil cylinder, the inner oil duct of piston rod is not dark, can adopt direct boring processing technology.
For big stroke oil cylinder, long its inner oil duct of piston rod is darker, is difficult to direct boring, can adopt the mode of soldering oil deferent in the box type piston bar.
When piston rod is hollow tubular, within it oil duct pipe 14 of welding be equivalent in the solid piston bar oil duct 2 ', hollow tubular itself then is equivalent to oil duct 2.
Claims (2)
1. a piston rod leads to oil cylinder; Comprise piston rod, it is characterized in that: in the described piston rod (1), have oil duct (2,2 '); One end of oil duct (2) is communicated with hydraulic fluid port (3); The other end is communicated with oil pocket (4), and an end of oil duct (2 ') is communicated with hydraulic fluid port (3 '), and the other end is communicated with oil pocket (4 ').
2. by the logical oil cylinder of the described piston rod of claim 1, it is characterized in that described piston rod (1) is a hollow tubular, in it, be welded with oil duct pipe (14).
