Description
Technical field
The present invention relates to labyrinth casing production equipment field is and in particular to brush steam seal brush ring rolling riveter.
Background technology
In order to reduce the gas leakage in the gap everywhere of steam turbine, ensure that steam turbine normal safe runs, therefore in vapour again
In turbine, spy is provided with various packings, and whole labyrinth ring is made up of multistage packing segmental arc body.The common packing of tradition mainly has comb
Tooth labyrinth gland and honeycomb steam seal etc. are hard to be sealed, and in order to adapt to deformation and the eccentric motion of turbine rotor, prevents contact from turning
Son causes rotor abrasion, must leave sufficiently large gap, thus such sealing effectiveness is as one wishes not to the utmost between labyrinth ring and rotor.
Brush flexibility packing increasingly receives publicity in recent years, and described brush steam seal is by by front panel, backboard be clipped between the two
The brush ring of high density high temperature alloy brush filament composition fall into and be embedded on labyrinth casing, due to brush filament adapt to rotor moment eccentric and clever
Live and quickly make a concession, the phenomenon of damaging rotor will not occur, be theoretically obtainable zero clearance seal, typically by gap in installation
Minimum is reduced to 0.05mm, and labyrinth casing material size is identical with former packing, but installs gap and only need the 1/3 to 1/2 of original design value,
Reduce flow area, thus decreasing leakage, packing effect is good.
Brush steam seal body, when producing, usually opens up groove on former labyrinth casing, then falls into brush ring and is embedded in groove manually
Beating point rivet clasp is fixed.Point rivet clasp is not only wasted time and energy surely, and production efficiency is difficult to improve, and difficult quality guarantee, brush ring with former
Labyrinth casing stable connection is poor.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of brush steam seal brush ring rolling riveter, and firm for brush ring roll riveting is solid
It is scheduled on labyrinth casing, apparatus processing replaces the riveting of artificial point, saves manpower, improves efficiency, and rivets firmly.
The present invention is achieved through the following technical solutions：
Brush steam seal brush ring rolling riveter, including the frame being made up of base, left and right pillar and entablature plate, described left and right is stood
" n " type slide block is slidably connected, slider top is connected with up-down adjustment bar, up-down adjustment bar is with the activity of entablature plate even between post
Connect, between slide block bottom, be provided with horizontal fixing axle, fixing axle is movably installed with hob head and hobboing cutter, below fixing axle, be provided with master
Moving axis, both ends of main drive shaft is rotatably connected on left and right pillar, and equipped with stop collar, one end of driving shaft fills fixed cover with driving thereon
Put and be in transmission connection.
The further improvement project of the present invention is to be provided with horizontally-guided bar above described fixing axle, and guide post two ends rotate peace
It is contained on slide block, guide post is movably installed with A fairlead, described fixing axle is provided with B fairlead, hob head movable set
On B fairlead, A fairlead is fixedly connected by connecting plate with B fairlead.The guide post being connected is set, during hobboing cutter operating
More steady.
The present invention further improvement project is that described hob head passes through back-to-back angular contact ball bearing movable set in B
On fairlead.Angular contact ball bearing can bear the radial and axial joint load and moment load based on larger radial load,
Limit B fairlead and hob head bi-directional axial displacement well.
The present invention further improvement project is that described horizontally-guided bar and A fairlead are supporting trapezoidal screw and ladder
Shape nut.Described up-down adjustment bar is trapezoidal screw, and its bottom is rotatably connected on slide block, and upper end is installed on trapezoidal nut and makes
C fairlead in, C fairlead is fixed on entablature plate.Trapezoidal screw can achieve bi-directional, manufacturability with trapezoidal nut
Good, root of the tooth intensity is high, rotates horizontally-guided bar（Trapezoidal screw）, can easily move A fairlead（Trapezoidal nut）Position, with
Sample rotates up-down adjustment bar, can easily carry movable slider to run up and down.
The present invention further improvement project is to be installed with revolving sleeve on described driving shaft, the fixing suit of stop collar
On revolving sleeve.During rolling riveter operating, labyrinth casing between driving shaft and hobboing cutter for the clamping constantly rubs driving shaft, thus is leading
Revolving sleeve is set with moving axis, stop collar is fixed on revolving sleeve again, labyrinth casing directly contacts friction with revolving sleeve, revolving sleeve grinds
After damage, change revolving sleeve in time, in preventing from operating for a long time, driving shaft is impaired.
The present invention compared with prior art, has following obvious advantage：
Firm for brush ring roll riveting can be fixed on composition brush steam seal body on labyrinth casing by the present invention, and apparatus processing replaces artificial
Point riveting, saves manpower, improves efficiency, and rivets firmly.
