Abstract
The utility model relates to a kind of oil cylinder, especially relates to a kind of correction oil cylinder.Its mainly solve the support strength of the oil cylinder existing for prior art and wear resistance poor, more unstable during operation, resistance to pressure is inadequate, thus causes the technical problem of shorter grade in the working life of whole oil cylinder.The utility model comprises cylinder barrel (1), it is characterized in that one end of described cylinder barrel (1) is provided with guide sleeve (2), in guide sleeve, cross-under has piston rod (3), piston rod the inner is connected with piston (4), the outer surface of piston is provided with copper layer (5), one end of piston is provided with locking nut (6), cylinder barrel has multiple hydraulic fluid port (7).
Description
Technical field
The utility model relates to a kind of oil cylinder, especially relates to a kind of correction oil cylinder.
Background technique
Current oil cylinder, its structure generally includes: cylinder body and the piston be arranged in inner chamber of cylinder block, inner chamber of cylinder block is divided into first half chamber and later half chamber by this piston, realizes piston move back and forth in cylinder body by being alternately pressed into hydraulic fluid in forward and backward half chamber in above-mentioned.Chinese patent discloses a kind of hydraulic jack (Authorization Notice No.: CN203847472U), it comprises cylinder barrel, cylinder bottom, guide sleeve, piston rod and piston, the first seal ring is provided with between guide sleeve and cylinder barrel, the first movable sealing structure is provided with between piston rod and guide sleeve, first movable sealing structure comprises " O " shape elastomer and is positioned at " YX " shape seal ring thereafter, be provided with Sealing mounting groove between piston and cylinder barrel, be provided with the second seal ring and baffle plate in mounting groove, baffle plate offers through hole; The 3rd seal ring is provided with between piston and piston rod; The front end of piston rod is provided with buffer plunger, is provided with earrings outside the rear end of piston rod; Earrings is connected with piston rod by tight split nut.But support strength and the wear resistance of this oil cylinder are poor, more unstable during operation, resistance to pressure is inadequate, thus causes the working life of whole oil cylinder shorter.
Model utility content
The utility model is to provide a kind of correction oil cylinder, its mainly solve the support strength of the oil cylinder existing for prior art and wear resistance poor, more unstable during operation, resistance to pressure is inadequate, thus causes the technical problem of shorter grade in the working life of whole oil cylinder.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
One correction oil cylinder of the present utility model, comprise cylinder barrel, one end of described cylinder barrel is provided with guide sleeve, in guide sleeve, cross-under has piston rod, and piston rod the inner is connected with piston, and the outer surface of piston is provided with copper layer, one end of piston is provided with locking nut, cylinder barrel has multiple hydraulic fluid port.Piston is supported and changes copper layer into by support ring, add support strength and the wear resistance of piston.Cylinder barrel solid forging has higher intensity, avoids welded unstability.The outer end of piston rod is spherical, and it serves the effect of correction.
As preferably, the internal surface of described guide sleeve is provided with DU lining.Guide sleeve supports and changes DU lining into by support ring, adds support strength and wear resistance.
As preferably, between described piston and cylinder barrel, between piston rod and guide sleeve, between guide sleeve and cylinder barrel, be all provided with O type circle.O type circle can strengthen the sealability of correction oil cylinder.
As preferably, between described guide sleeve outer end and piston rod, be provided with dust ring.Dust ring can prevent outside dust from entering in correction oil cylinder, thus ensures piston rod operably stability.
As preferably, the internal surface of described hydraulic fluid port is provided with the hydraulic fluid port screw thread of integral type.Hydraulic fluid port screw thread is directly processed on cylinder barrel, avoids welded unstability and non-resistance to pressure.Hydraulic fluid port Design of Screw Thread is tapered thread made in U.S.A, adds reliability and the sealing of connection.
Therefore, piston supports and changes copper layer into by support ring by the utility model, and add support strength and the wear resistance of piston, stability and the resistance to pressure of whole correction oil cylinder are higher, simple and reasonable for structure.
Accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is plan structure schematic diagram of Fig. 1.
Component, position and numbering in figure: cylinder barrel 1, guide sleeve 2, piston rod 3, piston 4, copper layer 5, locking nut 6, hydraulic fluid port 7, DU lining 8, O type circle 9, dust ring 10, hydraulic fluid port screw thread 11.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the one correction oil cylinder of this example, as shown in Figure 1, Figure 2, comprise cylinder barrel 1, one end of cylinder barrel is provided with guide sleeve 2, in guide sleeve, cross-under has piston rod 3, and piston rod the inner is connected with piston 4, and the outer surface of piston is provided with copper layer 5, one end of piston is provided with locking nut 6, cylinder barrel has multiple hydraulic fluid port 7.The internal surface of guide sleeve is provided with DU lining 8.O type circle 9 is all provided with between piston and cylinder barrel, between piston rod and guide sleeve, between guide sleeve and cylinder barrel.Dust ring 10 is provided with between guide sleeve outer end and piston rod.The internal surface of hydraulic fluid port is provided with the hydraulic fluid port screw thread 11 of integral type.
During use, after the inner chamber oil-feed of cylinder barrel 1, piston rod 3 can stretch in cylinder barrel, thus the spheroid of piston rod end can carry out rectification work.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the change done or modification are all encompassed among the scope of the claims of the present utility model.
