Abstract
The utility model discloses an oil cylinder with an oil-flowing piston rod and aim to provide the oil cylinder with the oil-flowing piston rod. The oil cylinder comprises the piston rod and is characterized in that an oil channel is opened in the piston rod. One end of the oil channel is communicated with an oil port, and the other end is communicated with an oil cavity. The piston rod is a hollow tube, and an oil channel tube is welded inside the piston rod. The oil cylinder with the oil-flowing piston rod is mainly suitable for an oil cylinder with a fixed piston rod and a cylinder body in a moving operation mode.
Description
Technical field
The utility model relates to a kind of logical oil cylinder, relates 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 purpose of the utility model is to provide a kind of piston rod to lead to oil cylinder, to overcome above-mentioned deficiency.
For realizing above-mentioned purpose, the technical solution of the utility model 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 beneficial effect of the utility model is: 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 the interior soldering oil deferent of box type piston bar of the utility model, 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 the structural representation of the utility model.
Fig. 2 is the structural representation of the utility model piston rod.
Fig. 3 is an embodiment's of the utility model piston rod a 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 utility model and embodiment thereof are done further explain.
Referring to accompanying drawing 1-3, the utility model comprises 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.
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).
