Bar 1 is fixed, and entire 1 total length of guide cone bar is 58mm.All end face edges of part, which process fillet using file, to be prevented
Piston packing ring is damaged, radius of corner R1 is 1mm.
Select the cylinder material of a Copper-zinc alloy material as force casing 2 blank, total length 75mm, outside
Diameter is 40mm, and internal diameter 30mm, open end hole depth is 60mm, starts to add in the outer surface of casing along closing one end using grinding machine
It is 34mm that work, which goes out outer diameter, and length is the thin segment of 55mm, retains boss face in open end, the height of boss face is 20mm, to increase
Damage of the installation process to lip is reduced to the force area of piston packing ring 8.Bottom cylindrical face using drilling machine in boss one end
On process a depth be 60mm, diameter be 25mm inner hole, reuse milling machine by inner hole be processed as internal diameter be 28mm hole,
Arrival end in hole process depth be 10mm, major diameter 30mm, path be 28mm groove, make 1 bottom surface of guide cone bar into
Enter to exert a force casing when can seamlessly transit.Other end sealing surface is as first end face 7, and sealing surface is with a thickness of 15mm, all ends of part
Face edge carries out fillet processing using file, and radius of corner R2 is 0.5mm.
Identical processing method can be used in guide cone bar 1 and force casing 2, is added according to the diameter of different piston packing rings 8
The various sizes of guide cone bar 1 of work and force casing 2, can adapt to the installation requirements to the piston packing ring 8 of different-diameter.
Guide cone bar 1 and force casing 2 carry out ruggedness test to all components when processing, and appearance cannot have a crackle, and zero
The edge flash of part is polished flat using file.
It is first that the top of piston packing ring 8 from guide cone bar 1 is (small when being installed using the tool to piston packing ring 8
Diameter section) it is inserted in, then the inner ring that the fixing seat 3 of guide cone bar 1 is inserted into piston ring retainer ring 9 is fixed, guarantees the same of installation
Axis and stability, piston packing ring 8 block after downslide a distance under self gravitation effect, at this time with force casing 2 from
After 1 top of guide cone bar is inserted in, after its raised head face is contacted as annulus force surface and piston packing ring 8, struck using hand hammer
The first end face 7 of force casing 2 is hit, piston packing ring 8 glides along guide cone bar 1 to be opened using the uniform elastic of itself, when
When reaching the minimum point in cone face, piston packing ring 8 opens up into maximum value, at this time since the cone face bottom of guide cone bar 1 is big
Diameter is greater than the installing port outer diameter 0.2mm of piston ring retainer ring 9, and piston packing ring 8 is just easily caught in piston ring retainer ring 9 very much, enters
Piston packing ring 8 shrinks rapidly clamping using the shrinkage of itself after retainer ring, is finally clipped in the upper positioning ring in piston ring retainer ring 9
Between 10 and lower positioning ring 11, installation effectiveness is improved while ensuring that installation quality in this way, and avoids damage piston
Sealing ring 8, specific installation process are shown in attached drawing 5.
Finally it should be noted that: above embodiments are only to illustrate the technical solution of this case rather than its limitations；Although
This case is described in detail referring to preferred embodiment, it should be understood by those ordinary skilled in the art that: still can be with
It modifies to the specific embodiment of this case or some technical features can be equivalently replaced；Without departing from this case technical side
The spirit of case should all cover in the claimed technical proposal scope of this case.
