Description
Technical field
The utility model relates to the mandrel of cylinder jacket lathe finish fixture, is specifically related to a kind of mandrel of the elastic expansion-sleeve of the fluidity for finish turning cylinder jacket fixture.
Background technology
At present, the mandrel that is used for the fluidity elastic expansion-sleeve fixture of finish turning cylinder jacket, have seal groove on its piston, after loading onto the O RunddichtringO, in hole, slide, described Kong Weiyi shoulder hole, this shoulder hole can only machine by turning because of structural limitations, so surface roughness does not reach requirement, strengthened the frictional force of sealing ring, sealing ring is easily damaged, once sealing ring damages the expanding force that will cause fixture, not cylinder jacket is skidded, damage cutter and lathe, affect production because changing sealing ring simultaneously, wasted manpower and materials.
Summary of the invention
The purpose of this utility model is: a kind of mandrel of cylinder jacket lathe finish fixture is provided, its piston and hole sliding pair be sealed into sealing, frictional force is very little, has extended the service life of sealing ring, and resistance to pressure is good.
Technical solution of the present utility model is: this mandrel comprise the mandrel body,
Gland, a y-type seal ring, No. two y-type seal rings and piston, a wherein end face of mandrel body is managed orchid, seam is established at the center of flange, establish bolt hole on the cylindrical wall of flange, establish successively shoulder hole on the axial line of mandrel body No. one, No. two shoulder holes, No. three shoulder holes and mesopore, establish cross bore on the circumferential wall of mandrel body, screw is established at the center, other end of mandrel body, screw, mesopore communicates with cross bore, the middle y-type seal ring separated with back-up ring, No. two y-type seal rings are arranged in No. two shoulder holes, the large end of gland is packed in shoulder hole and is bolted on the mandrel body, the small end of gland is packed in No. two shoulder holes and is compressed two y-type seal rings, piston is through the endoporus of gland, a y-type seal ring, the endoporus of No. two y-type seal rings and back-up ring is arranged in No. three shoulder holes, the inner circle of piston and gland, No. three shoulder holes are matched in clearance, whole formation mandrel.
Wherein, on mandrel body cylindrical wall, a flange and No. two flanges are established in interval.
During installation, the mandrel body is arranged on the lathe flange and by bolt hole and fixes by seam, flange, elastic expansion-sleeve and interference fit with it are installed between flange of mandrel body and No. two flanges, fill the fluidity filler through screw to the mandrel body interior, after filling the fluidity filler, with bolt, seal, the fluidity filler is full of in mesopore and cross bore the elastic expansion-sleeve transmission of pressure.
The utlity model has following advantage:
1, the sealing ring that the utility model mandrel is used is the Y type, and y-type seal ring is than O RunddichtringO long service life, and resistance to pressure is good.
2, the piston face grinding reaches Ra0.8, and piston moves back and forth in the endoporus of gland, No. three shoulder holes and y-type seal ring, and the frictional force of itself and sealing ring is very little, and seals fluidity filler, good sealing effect by y-type seal ring.
3, the utility model is simple in structure, easy to operate, has extended sealing ring service life, has saved the non-cutting time of changing sealing ring, alleviates maintenance personal's labour intensity.
