Description
Technical field
The utility model relates to a kind of steel tube expansion that diameter is expanded, steel pipe roundness is repaired, specifically a kind of boom tie of steel tube expansion.
Background technology
Being connected between the master cylinder that boom tie is used for steel tube expansion and the hole enlargement head is the critical component of transferring power, also is the stressed critical component of steel tube expansion.Boom tie is a double-decker; Skin is a sleeve, and inside is pull bar, and sleeve lining and pull bar outer wall are slidingly matched.Sleeve rear end is installed on the cylinder bracket, barrel forward end links to each other with the support set of hole enlargement head, back end of tie rod links to each other with the piston rod of oil cylinder, front end is installed the cone of hole enlargement head, sleeve plays location and supporting role at work, pull bar passes to the cone of hole enlargement head to power, by push-and-pull hole enlargement head steel pipe is carried out hole enlargement.
Because the length dimension of sleeve and pull bar is very big,, its linearity, required precision height, difficulty of processing is big.Pull bar length is 15235mm, and the pull bar diameter is Φ 310mm, belongs to slender rod piece processing, and the linearity of rod member is difficult to guarantee in the scope of instructions for use.Outer layer sleeve is about 11.3 meters in addition, and endoporus processing is also very difficult, if adopt conventional fairlead support guide at the sleeve two ends, because the deflection deformation of slender rod piece is difficult to assurance pull bar and the guiding clearance of sliding surface mating surface and required guiding accuracy.
Utility model content the purpose of this utility model provides a kind of difficulty of processing that alleviates, the boom tie of the steel tube expansion that cuts down finished cost.The deflection deformation that the pull bar of this boom tie and sleeve horizontal positioned are taken place is little, and linearity is good, the guiding clearance precision height between the face of being slidingly matched of pull bar and sleeve pipe.
To achieve these goals, the technical scheme that the utility model is taked is as follows: a kind of boom tie of steel tube expansion comprises pull bar and sleeve; It is characterized in that: sleeve is the segmented combining structure, and is fixedly connected between the two neighboring sections sub-sleeve, and the two ends of sleeve are fixed with fairlead, and it is guide locating device provided to, sleeve middle part two cover adjustable types to be installed along quill.
Adopt the utility model of technique scheme, because sleeve adopts split combination structure, sleeve constitutes by number cross-talk sleeve is fixedly connected, the length of each cross-talk sleeve is the part of sleeve total length, as be combined into the sleeve of 11 meters surplus length with three cross-talk sleeves, the length of average every cross-talk sleeve greatly reduces difficulty of processing less than 4 meters; And it is guide locating device provided that two cover adjustable types are installed at the middle part of sleeve.Be used for gap between adjusting yoke and the sleeve sliding surface, thereby greatly reduce requirement pull bar linearity precision; Greatly reduce processing cost.

The specific embodiment
Figure below further specifies the utility model technology in conjunction with the accompanying drawings.
As shown in Figure 1: the boom tie of steel tube expansion comprises pull bar 5 and sleeve 4; Sleeve 4 is the segmented combining structure, and the sleeve of present embodiment is combined by three cross-talk sleeves 401, and referring to Fig. 2: sub-sleeve 401 end faces of two sections Joints are provided with positioning step 403, and sleeve attachment screw 402 is fixedly connected with two cross-talk sleeves 401.The two ends of sleeve 4 are fixed with preceding fairlead 3, back fairlead 7, and preceding fairlead 3, back fairlead 7 are general fairleads.In order to prevent pull bar 5 distortion, along sleeve 4 axially, that sleeve 4 middle parts are equipped with two cover adjustable types is guide locating device provided, is used for tie-strut 5; One cover is to be uniformly distributed in radially three plane slide block assemblies 6 at same position of sleeve, and another set of is to be uniformly distributed in radially three circular arc slide block assemblies 8 at same position of sleeve.Nut 1 is used to connect ram shaft; Connecting bolt 2 is used for sleeve 4 is fixed on the oil cylinder frame.
As shown in Figure 3: position corresponding with three plane slide block assemblies 6 on the pull bar 5 is provided with guide surface 501; Sleeve 4 middle parts radially evenly are provided with three counterbores, and each counterbore is equipped with a plane slide block assembly 6; Plane slide block assembly 6 is made up of plane slide block 601 and fixed block 605; Between fixed block 605 and the sleeve 4 counterbore contact-making surfaces adjusting pad 603 is housed, fixed block 605 is fixedlyed connected with sleeve 4 through hold-down screw 606, fixed block 605 inner faces, the end face that promptly is bordering on the pull bar center of circle is through slide block attachment screw 602 mounting plane slide blocks 601, and plane slide block 601 inner faces and guide surface 501 are slidingly matched.
By repair adjusting pad 603 thickness, the relative position of adjustable leveling face slide block 601 and pull bar 5 well contacts three plate plane slide blocks 601 respectively, thereby pull bar 5 has been played the guide effect of support anti-rotation with three guide surface 501 that pull bar 5 is provided with.Because three plate plane slide blocks 601 can be adjusted by the thickness of independent adjusting adjusting pad 603, even pull bar 5 has local deformation, thickness by repair adjusting pad 603, plane slide block 601 is well contacted with guide surface 501, so reduced linearity requirement to pull bar 5, two fairleads 3 that reduced also that alternate 120 ° three guide surface, 501 determined inscribed circles of pull bar 5 and sleeve 4 two ends install and axiality, the position degree requirement at 9 places, thus the processing cost of pull bar 5 reduced significantly.
In order to make the good lubricating status of maintenance between plane slide block 601 and the pull bar 5, on plane slide block 601 and fixed block 605, be provided with oilhole 608, oil connection 607 is housed above the fixed block 605, oilhole 608 is equipped with oil pipe, is used for introducing lubricating oil from lubricated main line; Oil-pipe external wall between plane slide block 601 and fixed block 605 contact-making surfaces is installed sealing ring 604, prevents that lubricating oil from flowing out.
As shown in Figure 4: the another location at sleeve 4 middle parts radially evenly is provided with three counterbores, and each counterbore is equipped with a circular arc slide block assembly 8; Circular arc slide block assembly 8 is made up of circular arc slide block 801 and fixed block 605; Between fixed block 605 and the sleeve 4 counterbore contact-making surfaces adjusting pad 603 is housed, fixed block 605 is fixedlyed connected with sleeve 4 through hold-down screw 606, fixed block 605 inner faces, the end face that promptly is bordering on the pull bar center of circle is installed circular arc slide block 801 through slide block attachment screw 602, and circular arc slide block 801 circular arc end faces and pull bar 5 surfaces are slidingly matched.
Because of circular arc slide block 801 is that circular arc contacts with pull bar 5 surfaces, do not prevent pull bar 5 rotary actions, 8 of circular arc slide block assemblies play the support guide effect to pull bar 5.
