The specific embodiment
Can know that referring to Fig. 1 broken end taking-up instrument comprises action bars 1, line shaft 2, hand-tight nut 3, circumferential spacer pin 4, pull bar 5, expansion-head 6 and cambridge ring 7, wherein action bars 1 is a tubular structure; One end is provided with expansion-head 6, and the other end is provided with receives hand-tight nut 3, and expansion-head 6 is formed by connecting stiff end and expanding end; Connect stiff end and be provided with external screw thread, be used for being threaded with action bars 1 and being convenient for changing, expanding end by three or pintongs rubber-like cambered surface constitute; Can the pressurized distending, increase external diameter.Line shaft 2 is the cylinder of external diameter less than action bars 1 internal diameter, and is positioned over action bars 1 inside, and its end that is provided with thread segment stretches out action bars 1 and is threaded with hand-tight nut 3; The other end is connected with pull bar 5, is typically provided with cavity, and is provided with internal thread in the cavity; Be used for being threaded with pull bar 5, be provided with axial stopper slot at the outer surface of line shaft 2, this cell body matches with the circumferential spacer pin 4 of protrusion action bars 1 inwall; Thereby line shaft can only be axially rotated; And can't rotate, when circumferentially alignment pin 4 is installed, installing hole can be set on action bars 1; Circumferentially alignment pin 4 and installing hole interference fit insert circumferential alignment pin 4 installing hole and promptly accomplish assembling from action bars 1 inwall protrusion.Pull bar 5 was arranged in the cavity of action bars 1 and expansion-head 6, and the one of which end is fixed on the line shaft 2, and the other end is connected with the cambridge ring 7 of expansion-head 6 outer ends; The external diameter of this cambridge ring 7 thus, rotates hand-tight nut 3 greater than the internal diameter of expansion-head 6; Because the spacing fixation of circumferential spacer pin 4; Make the line shaft 2 can only axial displacement, thereby drive cambridge ring 7 axially-movables on pull bar 5 and the pull bar 5, cambridge ring 7 gets into or leaves expansion-head 6 expanding ends; Expansion-head 6 is deformed swell or withdraw normality, change expansion-head 6 outer end external diameters.
In order to strengthen the versatility of instrument; The vacuum tube that makes expansion-head 6 can insert different inner diameters 8 inside of breaking end; We are provided with the expansion-head of selecting for use of various outer diameter size for instrument, and are different to the model of expansion-head 6, can be equipped with the cambridge ring 7 of corresponding size; Perhaps increase the wall thickness of expansion-head 6, make the cambridge ring 7 of a model be common to the expansion-head of selecting for use of each model.For the ease of changing, pull bar 5 can adopt clamping with cambridge ring 7, also can adopt to be threaded; The shape of cambridge ring 7 is generally circular cone shape, and the less end of its diameter is connected with pull bar 5, and the end outer end that diameter is bigger is provided with protrusion cambridge ring 7 edges and is used for the spacing shaft shoulder; This shaft shoulder can be stuck on the outer end wall of expansion-head 6; Perhaps be stuck on the limited block that defaults in the expansion-head 6, thereby the degrees of expansion of confined expansion 6 is avoided parts damages.
When instrument uses; Expansion-head 6 needs to insert in the vacuum tube broken end 8; Therefore the external diameter of expansion-head 6 is less than vacuum tube 8 internal diameters that break end; Because be provided with the subsequent use expansion-head of a plurality of models, the external diameter of expansion-head 6 is not of uniform size, need to guarantee that action bars 1 external diameter is greater than break end 8 internal diameters and less than the internal diameter of sealing ring 9 on the booster housing of vacuum tube; But when expansion-head 6 external diameters during greater than action bars 1 external diameter, boss or bulge loop can be set on expansion-head 6, the diameter of these boss or bulge loop place circumference should be greater than break end 8 internal diameters and less than the internal diameter of sealing ring 9 on the booster housing of vacuum tube.
The removing method of vacuum tube broken end is to live will break end behind this broken end through a tool holding 8 to push in the vacuum booster housing cavity; And avoid breaking end and 8 fall in the cavity; Utilize the gap between instrument and the sealing ring 9 to take off sealing ring 9 afterwards; Take out instrument again and take off broken end 8, at last sealing ring 9 is reinstalled the original place, accomplish the taking-up work of broken end thus.
Specific to using instrument shown in Figure 1 to take out the method for broken end, concrete steps are following:
Change brake vacuum Guan Shixu it is extracted from booster, owing to reasons such as joint manufacturing defect, unbalance stress fracture, break end 8 in the withdrawal process inner formation of sealing ring;
At this moment, according to corresponding expansion-head 6 of the size Selection of vacuum tube broken end and installation, when changing expansion-head 6; At first rotate hand-tight nut 3, make cambridge ring 7, be in not and expansion-head 6 state of contact to extrapolation; Again cambridge ring 7 is unloaded; Take off former expansion-head 6, with the expansion-head 6 that is fit to action bars 1 one ends of packing into, load onto cambridge ring 7 then and promptly accomplish replacing afterwards;
After more finishing changing expansion-head 6, the state that keeps expansion-head 6 to be in the normal state, if do not change 6 of expansion-head need the hand-tight nuts 3 of rotation with the cambridge ring 7 on pull bar 5 and pull bar 5 tops to extrapolation, expansion-head 6 is in the normal state;
The expansion-head 6 of instrument is inserted in the vacuum tube broken end; Rotating hand-tight nut 3 inwardly draws the cambridge ring 7 on pull bar 5 and pull bar 5 tops; Force expansion-head 6 distortion distendings; And the external diameter of expansion-head 6 distendings part, then is threaded to hand-tight nut 3 can't turn to get final product because cambridge ring 7 is provided with the spacing shaft shoulder greater than the internal diameter in the vacuum tube broken end 8;
Utilize the shaft shoulder or the boss on the expansion-head 6 of tool operation bar 1 that vacuum tube broken end 8 is pushed in the vacuum booster housing cavity; Because the broken end internal diameter is less than expansion-head 6 external diameters after expanding; Then broken end can not fallen in the cavity; Utilize the gap between action bars 1 and the sealing ring 9 afterwards, sealing ring 9 is removed;
Afterwards, sealing ring 9 and the vacuum tube broken end 8 that is stuck on the expansion-head 6 are taken out of from the sealing ring installing hole together;
