Abstract
The utility model discloses a long-stroke pusher hydraulic cylinder piston rod guide, which comprises a shaft (10) arranged below a support (3). A bearing (8) is arranged on the inner side of a guide wheel (7), the shaft (10) penetrates through a center hole of the bearing (8) and disposed on the lower portion of the support (3), and two sides of the bearing (8) are provided with end caps (9). Besides, the guide wheel (7) is an eccentric wheel. The long-stroke pusher hydraulic cylinder piston rod guide with the structure resolves problems about stability and sealing performance of piston rods during actual production, and is stable in operation, simple in structure and lower in manufacture cost relatively. Moreover, the guide wheel moves to rotate on the upper surface of a roller body on a roller bed to form a fulcrum, then bending deformation and stress of piston rods can be reduced and working strength of the piston rods is reduced, thereby protecting seal rings of hydraulic cylinder and avoiding hydraulic oil leakage.
Description
Technical field
The utility model relates to a kind of steel-pushing machine, relates in particular to a kind of long stroke steel-pushing machine hydraulic cylinder piston rod guiding device.
Background technique
At present, long stroke steel-pushing machine is used widely on a lot of production lines, but in actual use, also exists some problems.
(1) poor stability
During long stroke steel-pushing machine hydraulic cylinder works, because stroke is longer, when bearing than high thrust, piston rod is owing to can not keep original present situation to occur bending and deformation, thereby vertically producing the bigger bigger additional bending stress of moment of flexure generation, if exceed allowable stress or distortion exceeds permission range, cause the hydraulic cylinder piston rod unstability, also can fracture under the serious situation.
(2) sealing is poor
During long stroke steel-pushing machine hydraulic cylinder works, when piston rod bending deflection was big, the Sealing distortion in the cylinder ends position will be bigger, when exceeding permission range, causes hydraulic oil to reveal easily.
The model utility content
The purpose of this utility model provides and a kind ofly can reduce the long stroke steel-pushing machine hydraulic cylinder piston rod guiding device that piston rod occurs bending and deformation.
To achieve these goals, by the following technical solutions:
A kind of long stroke hydraulic cylinder piston rod guiding device is characterized in that: described guiding device comprises the axle that is arranged at the bearing below, and the inboard of upper saw pulley is provided with bearing, and axle passes the center hole of bearing, is arranged at the bottom of bearing.
In order to reduce the life-span of improving bearing, reduce dust, the both sides of described bearing are provided with end cap.
In order to regulate the distance between upper saw pulley and the roller-way, described upper saw pulley is an eccentric wheel.
Structure of the present utility model solves the stability and the sealing problem of piston rod in the actual production working procedure, and a kind of working stability, simple in structure and hydraulic cylinder piston rod guiding device that manufacture cost is relatively low are provided.Upper saw pulley moves to roller roller and rotates on the surface on one's body, forms a fulcrum, can reduce the bending deflection and the flexural stress of piston rod, reduces the working strength of piston rod, thereby protection hydraulic cylinder sealing circle prevents the hydraulic oil leakage.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1 along B-B;
Fig. 3 is the plan view of Fig. 1.
Among the figure: part 1 is a piston rod, and part 2 is earrings, and part 3 is bearings, and part 4 is axle head baffle plates, and part 5 is coupling shafts, and part 6 is spacer sleeves, and part 7 is upper saw pulleys, and part 8 is bearings, and part 9 is end caps, and part 10 is axles, and part 11 is lubricating cups.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is further described:
As shown in Figure 1 to Figure 3:
Piston rod 1 is connected on the coupling shaft 5 that is fixed on bearing 3 by earrings 2, and the two ends of coupling shaft 5 are fixed with axle head baffle plate 4, and axle head baffle plate 4 can effectively prevent the rotation of coupling shaft 5, guarantees that moving on the Vertical direction can not appear in piston rod 1.Be provided with spacer sleeve 6 between the earrings 2 and between the coupling shaft 5.
The bottom of support 3 is provided with axle 10, and axle 10 is provided with the upper saw pulley 7 that has bearing 8, and the inboard of upper saw pulley 7 is provided with the bearing 8 that both sides have end cap 9, and axle 10 passes the center hole of bearing 8.One end of axle 10 is provided with lubricating cup 11, has made things convenient for lubricated.
When piston rod 1 stretched out certain distance, upper saw pulley 7 moved to roller roller and rotates on the surface on one's body, forms a fulcrum; can reduce the bending deflection and the flexural stress of piston rod; reduce the working strength of piston rod 1, thereby protection hydraulic cylinder sealing circle prevents the hydraulic oil leakage.
Wherein upper saw pulley 7 can be eccentric wheel, by the position of adjusting axle 10, regulates eccentric offset like this, thereby regulates the gap between eccentric wheel and the body surface, to satisfy piston rod 1 levelness requirement.
