Accompanying drawing explanation
The using state sectional view of the range piston cylinder sleeve pull-out accessory that Fig. 1 provides for the embodiment of the present invention;
The profile of the first sleeve in the range piston cylinder sleeve pull-out accessory that Fig. 2 provides for the embodiment of the present invention.
In Fig. 1 and Fig. 2, Reference numeral is: 1 first sleeve, 1a first projection, 1b second projection, 1c the 3rd projection, 2 second sleeves, 3 screw rods, 4 first annulus, 5 bolts, 6 second annulus, 7 annular buckles, 8 piston-cylinders, 9 housings.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
As shown in Figure 1, a kind of range piston cylinder sleeve pull-out accessory, comprises the first sleeve 1, second sleeve 2 and screw rod 3.Wherein the material of the first sleeve 1 is for being 40Cr, piston-cylinder material is structural alloy steel GCr15,40Cr and GCr15 process based prediction model is substantially close, there are higher intensity and case hardness, and there is wearability, in use, both can ensure that accessory is not damaged, and can increase again the service life of accessory.As shown in Figure 2, one end of the first sleeve 1 is coniform, and the other end is cylindric, the outer face, end of this first sleeve 1 conical end is provided with annular the first protruding 1a, the inwall of the first sleeve 1 cylindrical end is provided with annular the second protruding 1b.Second sleeve 2 is inserted in the cylindrical end of the first sleeve 1, the outer wall of this second sleeve 2 is provided with the annular groove that 1b protruding with second matches.Screw rod 3 coordinates with the inner thread of the second sleeve 2, and successively through the second sleeve 2 and the first sleeve 1.
For the ease of assembling, this first sleeve 1 is spliced by two parts of centrally axisymmetrical, and the tapering of conical end is for being preferably 2 °, structure like this, second sleeve 2 is just relatively easily assembled in the first sleeve 1, and the first sleeve 1 is more prone to pass from range piston cylinder sleeve.
End for the ease of the first sleeve 1 cylindrical end is inwardly shunk, and the first protruding 1a on the first sleeve 1 is opened, and preferably, the end of the first sleeve 1 cylindrical end is provided with the clamp system for inwardly being clamped this end.As shown in Figure 2, this clamp system comprises the end that the first annulus 4 and bolt 5, first annulus 4 are sleeved on the first sleeve 1 cylindrical end, and the outer wall of this first annulus 4 is provided with screwed hole, the axis of this screwed hole and the axes normal of the first annulus 4, bolt 5 is arranged in screwed hole.In addition, clamp system also can adopt the structure of similar pipe clamp to reach identical object.
If the end of the first sleeve 1 cylindrical end is inwardly shunk too serious, tensile force between the second protruding 1b in annular groove on second sleeve 2 and the first sleeve 1 is excessive, cause the distortion of the first sleeve 1 and the fracture of the second sleeve 2, in order to avoid the generation of above-mentioned situation, preferably, on the first sleeve 1 outer face, the position corresponding with the second protruding 1b is provided with position limiting structure.Position limiting structure, comprising: the second annulus 6, annular buckle 7, the protruding 1c of annular the 3rd be arranged on the first sleeve 1 outer face.Wherein, the second annulus 6 its be sleeved on position on the first sleeve 1 outer face, corresponding with the second protruding 1b.Further preferably, the outer face matched in clearance of the second annulus 6 and the first sleeve 1, this gap is that the end of the first sleeve 1 cylindrical end is inwardly shunk, and the second protruding 1b expands outwardly and provides accommodation space, thus just makes the first protruding 1a open.In order to prevent the second annulus 6 play vertically on the outer face of the first sleeve 1, preferably, the first sleeve 1 outer face arranges annular the 3rd protruding 1c, and the 3rd protruding 1c is connected with the first sleeve 1.One end of second annulus 6 and the end face of the 3rd protruding 1c are fitted, second annulus 6 is between the first annulus 4 and the 3rd protruding 1c, and annular buckle 7 is sleeved on the outer face of the first sleeve 1, between the first annulus 4 and the second annulus 6, the other end of the second annulus 6 and the end face of annular buckle 7 are fitted.Annular buckle 7 and the 3rd protruding 1c serve axial limiting effect to the second annulus 6, prevent this second annulus 6 that play occurs.Considering range piston cylinder sleeve pull-out accessory in use, can there is small expansion in the second annulus 6, occurs that the possibility of this second annulus 6 unidirectional play is vertically comparatively large, only can arrange annular buckle 7 or the 3rd protruding 1c for this reason.
A kind of embodiment, annular groove on second sleeve 2 is positioned at the lower end of the second sleeve 2, on second sleeve 2 inwall, the position corresponding with annular groove be provided with internal thread, and screw rod 3 matches with this internal thread, is provided with gap between the inwall of the second sleeve 2 upper end and screw rod 3.As shown in Figure 1, range piston cylinder sleeve pull-out accessory in use, easily airtight space is formed between first sleeve 1, piston-cylinder 8, housing 9, screwing screw rod 3 like this can be very difficult, gap is provided with between the inwall of the second sleeve 2 upper end and screw rod 3, just can pass air into, break the airtight of space, be convenient to screw screw rod 3.
Operating personnel are when carrying out piston-cylinder pull-out, first screw rod 3 unscrewed and bottom screw rod 3, be no more than the first protruding 1a, thus guarantee that the conical end of the first sleeve 1 can be placed into bottom the sleeve port of housing 9 completely, then left hand buttresses accessory, slightly to lower firmly, reaffirm whether in the bottom of the sleeve port of housing 9.Right hand swivel bolt 5, the end of the first sleeve 1 cylindrical end is inwardly shunk, annular groove on second sleeve 2 is by protruding for second on the first sleeve 1 1b jack-up, first protruding 1a starts to open, when bolt 5 screws stopping, at this moment the bottom of the first protruding 1a seized piston cylinder sleeve, then right hand rotary screw 3, stop time bottom screw rod 3 lower contacts to housing 9, then with monkey wrench or open-end wrench continue slowly screw screw rod 3, when piston-cylinder 8 obviously departs from housing (at this moment proving that claw is seized cylinder sleeve completely), can accelerate to screw speed, until cylinder sleeve 8 and accessory thoroughly depart from from housing 9, looser a bolt 5 again, accessory is separated can carries out subsequent operation with piston-cylinder 8.
This range piston cylinder sleeve pull-out assistant tool structure is simple, convenient operation, can be pulled out from housing by range piston cylinder sleeve easily.By to application of the present invention, in gear-box production line debug process, utilize this accessory can carry out repeated disassembled and assembled to gearshift piston-cylinder, greatly reduce the quantity to exemplar demand in production line debugging, and operating personnel can be allowed repeatedly to carry out changer exercise, reach the operation being familiar with equipment, thus can greatly enhance productivity.Additionally by the use to this accessory, in actual production process, because of human users's error or the problem because of workpiece self, press-fit underproof workpiece to cylinder sleeve can reprocess very soon, reduce the scrappage of workpiece, saved production cost, improve the economic benefit of enterprise.
In sum, content of the present invention is not limited in the above-described embodiments, and those skilled in the art can propose other embodiment easily according to guiding theory of the present invention, and these embodiments all comprise within the scope of the present invention.
