Description
Technical field
The present invention relates to hydraulic packing fields, in particular to a kind of plunger ring press-fitting tool.
Background technique
Plunger ring is generally used for the sealing element being sealed between oil cylinder and piston rod.The installation quality of plunger ring is direct
It is related to the qualification rate of hydraulic device, also, the installation effectiveness of plunger ring directly affects the production efficiency and maintenance cycle of equipment.
The relevant technologies provide a kind of sealing element mounting tools for piston ring.Fig. 1 is being used for for the relevant technologies offer
The schematic diagram of the sealing element mounting tools of piston ring, as shown in Figure 1, the installation tool include transition axis set 1, elastic propeller 2,
Centering spindle 3 and O-ring 6；Wherein, the big end end face internal diameter of transition axle sleeve 1 and piston diameter match, and outer circle is smooth taper face,
Big end inner face edge is right up to 4 slot edge of sealing ring, and small end is furnished with centering spindle 3；The import internal diameter of elastic propeller 2 is between mistake
It crosses between the big small end of axle sleeve, several through slots is provided on external cylindrical surface, the promotion length of elastic propeller 2 is equal to transition axle sleeve 1
Length, tail end, which has, determines core bore, and the centering spindle 3 of size and transition axle sleeve 1 matches, and guarantees elastic propeller 2 and transition axle sleeve 1
Concentricity.
When specific implementation installation, O-ring 6 is fitted into advance in 5 bottom diameter of groove, by 1 set of transition axle sleeve on piston, makes axis
Set big end end face edge reaches lattice to enclose the edge of groove 5, and the circular conical surface of transition axle sleeve 1 is filled with cleaning hydraulic oil, and lattice are come
4 sets of circle is above；Elastic propeller 2 is set on transition axle sleeve 1 by centering spindle 3, and is pushed ahead；Fast direct pushes away elasticity and pushes away
Into device 2, lattice uniformly open to enclose 4 along smooth 1 outer circumference surface of transition axle sleeve, and lattice enclose 4 groove 5 at the sound after pushing in place,
After lattice are to enclose 4 arrival grooved positions and spring into slot, the sealing element mounting tools are taken away.
There are following technical problems for the piston ring mounting tools that above-mentioned the relevant technologies provide:
First, when elastic propeller pushes sealing element to move along the periphery of transition axle sleeve, elastic propeller and rigid axle sleeve
It contacting and is gradually softened, final realize promotes sealing element in groove, since propeller is elastic material and need to be softened, because
This propeller is easy to be worn and even deform, and is difficult to ensure that Glais ring is accurately installed, and the work is directly resulted in after use for several times
The durability of tool is low.
Second, the installation tool that the relevant technologies provide can only install elastic sealing element, rigid seal can not be installed, only
Use scope is limited to.

Place.
In the present embodiment, push piece 201 has multiple pushing rams 2011, multiple pushing rams 2011 with it is multiple
The grafting correspondingly of guide groove 101；Push piece 201 and secondary push piece 202 are respectively provided with 2011 He of a multiple pushing ram
The set fishplate bar 2012 of multiple secondary pushing rams 2021, a push piece has multiple spliced eye 2012a, multiple pushing rams 2011
It is successively arranged alternately with multiple spliced eye 2012a along the circumferential direction of set fishplate bar, multiple secondary pushing rams 2021 and multiple spliced eyes
2012a grafting correspondingly, so that entire tooling keeps balance.
In the present embodiment, propulsive mechanism 20 further includes being socketed in the elastic component 204 determined on chipware 203；Also, elastic component
204 between a push piece 201 and secondary push piece 202.Preferably, which is spring.By the way that elastic component is arranged,
Convenient for the propulsion of secondary push piece；Also, the presence of elastic component can easily adjust the propulsion process of a push piece and secondary push piece.
Push piece and secondary push piece are rigid member, also, the slot bottom of a pushing ram, secondary pushing ram, guide groove
It is arranged with the centerline parallel of guideway.
In the present embodiment, there are many set-up modes of determining chipware, determine between chipware and guiding tapered sleeve can mutually from or it is living
Dynamic grafting.
Preferably, determining chipware is screw element, and screw element can be stud, the socket of the set fishplate bar, secondary push piece of a push piece
Plate and elastic component are socketed in the smooth domain of stud, which is bolted with nut and gasket, pass through column cap and the nut
Push piece, secondary push piece and elastic component are limited in smooth domain section.Chipware is determined using this kind, chipware is determined and guiding tapered sleeve is same
Axis and mutually from its advantage is that propulsive mechanism is easy to disassemble.Alternatively, a locating slot is arranged in the miner diameter end in guiding tapered sleeve, it is fixed to make
Chipware can be plugged in the locating slot, to determine chipware with this and guiding tapered sleeve holding is coaxial, the advantage of which is coaxial
Positioning is quick, accurate.Certainly, the combinable use of above two mode.
Preferably, the center for being oriented to the bigger diameter end end face of tapered sleeve 10 is provided with cone core column 102；Cone core column 102 and big
Diameter end end face is vertical, and for the location hole grafting with 200 end face of plunger, when use makes determining for cone core column 102 and 200 end face of plunger
The coaxial positioning of guiding tapered sleeve 10 and plunger 200 is realized in position hole grafting.
Preferably, the bigger diameter end for being oriented to tapered sleeve 10 is provided with multiple arcs clamping portion 103；103 edge of multiple arcs clamping portion
The outer periphery of bigger diameter end is successively spaced setting, and multiple arcs clamping portion 103 is used to be clamped with the outer periphery of plunger 200, when use
The outer periphery of multiple arcs clamping portion 103 and plunger 200 is clamped to realize positioning.
Press-fitting tool provided in an embodiment of the present invention is completed by the matching that propulsive mechanism and guide cone cover upper guide groove
The press fitting of plunger ring, elastic propeller and the male cone (strobilus masculinus) of rigidity tapered sleeve directly contact and cause to be softened substitution in the related technology
Scheme, the advancing movement of propulsive mechanism are not influenced by the conical surface of guiding tapered sleeve, and pressure can be completed in the case where remaining unchanged shape
Industry is pretended, it is final to realize the purpose that plunger ring is promoted to annular groove.Since propulsive mechanism is not necessarily to strut in advancing movement, push away
It is not easy to be worn or deform into mechanism, durability is high, long service life；Also, scheme provided by the invention is used, it can also be real
The installation of existing rigid seal, use scope is not by the limitation of plunger ring material.In addition, press fitting work provided in this embodiment
Dress, structure is simple, operation is reliable, durable and laborsaving.
The foregoing is merely the preferred embodiment of the present invention, are not intended to restrict the invention, for this field
For technical staff, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any
