Description
Technical field
This utility model belongs to technical field of hydraulic equipment, relates to the assembly on a kind of piston rod, particularly relates to assembly on the graphite copper sheathing formula piston rod of a kind of alternative guidance tape.
Background technology
Hydraulic cylinder is most basic hydraulic test, its range is extremely wide, the integral type end cap seal that cylinder ends face seal is tightened frequently with spiral, piston rod passes end cap central, piston acts in hydraulic cylinder, but this mode exists the coaxial precision problem of piston rod and hydraulic cylinder endoporus, piston eccentric wear phenomenon easily occurs during use, affects the working life of piston packing；In order to solve coaxial precision problem, occur a kind of to external seal with the mode of internal seal combination, wherein internally seal and eliminate coaxiality error with piston rod, and piston rod is defined the effect of support, but increase and inner seal liner there is also certain weak point, especially piston rod axially-movable is by certain frictional resistance, in order to solve frictional resistance problem, use guidance tape (resin copper powder) to solve anti-attrition and guide problem, but when piston bears bigger load, guidance tape easily produces plastic deformation, so internal sealing ring one end is squeezed, the other end just produces leakage.
Utility model content
This utility model produces plastic deformation for above-mentioned guidance tape when bearing bigger load, sealing ring extruding occurs that the deficiencies such as leakage make improvements, assembly on the graphite copper sheathing formula piston rod of a kind of alternative guidance tape is proposed, bearing capacity radially can be increased, improve the fluency of piston rod movement, the work efficiency of lifting means is had preferable facilitation.
The technical solution of the utility model is: assembly on the graphite copper sheathing formula piston rod of a kind of alternative guidance tape, including working cylinder end cap, hydraulic cylinder and piston rod；It is characterized in that: the end of described hydraulic cylinder is sequentially provided with inner seal, graphite copper sheathing assembly and outer seal from inside to outside, described graphite copper sheathing assembly is arranged on the inside of described inner seal, described outer seal is connected against inner seal and graphite copper sheathing assembly screwing with hydraulic cylinder, described outer seal, graphite copper sheathing assembly and inner seal are all nested with on described piston rod and form sliding connection with piston rod, and described graphite copper sheathing assembly is made up of with copper ring graphite body.
Described graphite copper sheathing assembly is made up of copper ring and graphite body, and copper ring is machined with several through holes, and graphite body is inlayed in through-holes and forms integral structure with copper ring.
The beneficial effects of the utility model are: assembly on the graphite copper sheathing formula piston rod of a kind of alternative guidance tape that the utility model proposes, simple in construction, operation principle is clear, the mode using graphite copper sheathing combined with interior external seal instead of conventional resins copper powder guidance tape, in this structure, graphite plays self-lubricating function, copper sheathing plays anti-attrition effect, decreases the resistance of motion of piston rod, makes piston rod movement the most smooth, decrease the eccentric wear of piston rod, extend the working life of sealing ring；Meanwhile, copper sheathing also makes radially bearing capacity be increased, and improves the work efficiency of equipment.
Accompanying drawing explanation

Fig. 2 is the structural representation of graphite copper sheathing in this utility model.
In figure: piston rod 1, working cylinder end cap 2, inner seal 3, hydraulic cylinder 4, outer seal 5, graphite copper sheathing assembly 6, copper ring 6-1, graphite body 6-2.
Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, assembly on the graphite copper sheathing formula piston rod of a kind of alternative guidance tape, including working cylinder end cap 2, hydraulic cylinder 4 and piston rod 1；The end of hydraulic cylinder 4 is sequentially provided with inner seal 3, graphite copper sheathing assembly 6 and outer seal 5 from inside to outside, graphite copper sheathing assembly 6 is arranged on the inside of inner seal 3, outer seal 5 is connected against inner seal 3 and graphite copper sheathing assembly 6 screwing with hydraulic cylinder 4, outer seal 5, graphite copper sheathing assembly 6 and inner seal 3 are all nested with on piston rod 1 and form sliding connection with piston rod 1, and graphite copper sheathing assembly 6 is made up of with copper ring 6-1 graphite body 6-2.
As shown in Figure 2, assembly on the graphite copper sheathing formula piston rod of a kind of alternative guidance tape, graphite copper sheathing assembly 6 is made up of copper ring 6-1 and graphite body 6-2, and copper ring 6-1 is machined with several through holes, and graphite body 6-2 inlays in through-holes and forms integral structure with copper ring 6-1.
This utility model simple in construction, operation principle is clear, the mode using graphite copper sheathing combined with interior external seal instead of conventional resins copper powder guidance tape, in this structure, graphite plays self-lubricating function, copper sheathing plays anti-attrition effect, decrease the resistance of motion of piston rod, make piston rod movement the most smooth, decrease the eccentric wear of piston rod, extend the working life of sealing ring；Meanwhile, copper sheathing also makes radially bearing capacity be increased, and improves the work efficiency of equipment.
