Abstract
The utility model discloses a special fixture for assembling steam seal rings. The fixture comprises a circular template and a plurality of press fitting parts, wherein a stop port is formed in the upper part of the circular inner wall of the template; a plurality of fixing holes are formed in the multiple circumferential circles with different diameters on the template; each press-fitting part comprises an upright column I, an upright column II and a press-fitting block; the upright columns I penetrate through the fixing holes, and the press-fitting blocks are located at the top of the upright columns I; the bottom of each steam seal section is propped in the stop port, the top is propped against one end of each press-fitting block, each upright column II and each upright column I are parallelly penetrate through the other end of the press-fitting block, and the bottom are propped against and fixed on the template. The inner diameter of the stop port can be enlarged through continuous turning, the fixing hole and the press-fitting part mounted in the fixing hole on each circle are matched, then the steam seal rings with different diameters are assembled, the fixture can be used repeatedly in one program, and alignment is not required to be found again when the steam seal rings with different diameters are processed, so that the processing errors are reduced, the finished product precision is increased, the processing efficiency is increased, and the material cost is saved greatly.
Description
Technical field
the utility model relates to turbine steam seal processing mold field, is specifically related to the assembled special fixture of steam seal ring.
Background technology
The gland seal structure of steam turbine mostly is Comb Labyrinth Seals structure at present, the practical technique of brush seal in 2000 is applied in aero-engine, steam turbine and gas turbine, compare traditional Comb Labyrinth Seals, it is eccentric and make a concession fast flexibly that brush seal can adapt to moment of rotor, significantly improve the stability of rotor, and amount of leakage is only 1/5～1/10 of labyrinth seal, improve exerting oneself of steam turbine, reduce steam turbine running oil consumption.Therefore on former broach labyrinth casing, install brush ring additional at present, repacking brush steam seal into is that numerous steam turbines use producer's transformation first-selected.Part producer provides Liao Yuan producer broach steam seal ring spare part, on this packing body, installs brush ring additional, need on former packing body, slot.In process, first packing section to be carried out assembled, then processing.The design of steam seal ring assembling clamp is to working (machining) efficiency, processing cost important.
Summary of the invention
The technical problems to be solved in the utility model is to provide the assembled special fixture of a kind of steam seal ring, can in a project, repeatedly use, and different-diameter steam seal ring is added to man-hour without alignment again, reduce mismachining tolerance, improve finished product accuracy, improve working (machining) efficiency, and greatly save material cost.
The utility model is achieved through the following technical solutions:
The assembled special fixture of steam seal ring, described fixture comprises an annular template and multiplely press-fits part, seam is offered on template circle ring inner wall top, the isometrical week of template is upwards provided with multiple fixing holes, describedly press-fit part and formed by I column, II column and press-fit block, I column bottom is installed in fixing hole, press-fit block is positioned at I column top, packing section base abuts is in seam, top is leaning press-fit block one end, II column the be installed on press-fit block other end parallel with I column, its base abuts is fixed in template.
The further improvement project of the utility model is that described fixing hole is along isometrical being circumferentially evenly distributed.Stressed even, firm when clamping steam seal ring.
The utility model further improvement project is in described template, to be provided with the circumferential fixing hole of multi-turn of different-diameter.Fixing hole is arranged on multi-turn week upwards according to the diameter of steam seal ring to be assembled, can expand seam internal diameter by continuous turning, coordinates the fixing hole on each circle and the part that press-fits is wherein installed, and carrys out the steam seal ring of assembled different-diameter.In a project, can repeatedly use, different-diameter steam seal ring is added to man-hour without alignment again, reduce mismachining tolerance, improve finished product accuracy, improve working (machining) efficiency, and greatly save material cost.
For the ease of being arranged on lathe, the utility model further improvement project is that described template reverse side center ring position is provided with circular bosses.
In order conveniently to press-fit the dismounting of part, the utility model further improvement project is, described I column is stud, adopts nut to fix, and II column is hexagon socket head cap screw, is tightened.
The utility model compared with prior art, has following obvious advantage:
The utility model can expand seam internal diameter by continuous turning, coordinates the fixing hole on each circle and the part that press-fits is wherein installed, and carrys out the steam seal ring of assembled different-diameter.In a project, can repeatedly use, different-diameter steam seal ring is added to man-hour without alignment again, reduce mismachining tolerance, improve finished product accuracy, improve working (machining) efficiency, and greatly save material cost.
Brief description of the drawings
Fig. 1 is the utility model top view.
Fig. 2 is A-A amplification view after Fig. 1 clamping steam seal ring.
Detailed description of the invention
As Fig. 1, shown in Fig. 2, fixture described in the utility model comprises an annular template 1 and multiplely press-fits part 2, seam 11 is offered on template 1 circle ring inner wall top, in described template 1, be provided with the circumferential fixing hole 12 of seven circles of different-diameter, every circle fixing hole 12 is evenly distributed, describedly press-fit part 2 by I column 21, II column 22 and press-fit block 23 form, I column 21 bottoms are installed in fixing hole 12, press-fit block 23 is positioned at I column 21 tops, packing section 3 base abuts are in seam 11, top is leaning press-fit block 23 one end, II column 22 be installed on press-fit block 23 other ends parallel with I column 21, its base abuts is fixed in template 1.
Described I column 21 is stud, adopts nut to fix, and II column 22 is hexagon socket head cap screw, is tightened in template.
In same project, according to required assembled steam seal ring diameter, in template, offer multi-turn fixing hole.First be arranged in the fixing hole of innermost circle press-fiting part, the steam seal ring of assembled diameter minimum is processed, after completing, turning expands seam internal diameter, move in the fixing hole of the second circle press-fiting part, large some steam seal ring of assembled diameter, so constantly turning progressively expands seam internal diameter, in a project, can repeatedly use, and carrys out the steam seal ring of assembled different-diameter.
For the ease of fixture is arranged on lathe, described template 1 reverse side center ring position is provided with circular bosses 13.
