Abstract
Ke nuoer cylinder body is sealed child device of cylinder body for airtight test relates to railway ke nuoer cylinder body airtight test technical field for the high -speed vehicle, and it includes lock nut, nut, taut piece, clamp plate, seal cover, intake pipe joint, O type sealing washer, cylinder lock nut, sealed matrix and strains the cylinder. The utility model discloses a sealed child device utilizes the elasticity of seal cover, and to rise by shape sealed with the screw hole on cylinder body and the cylinder body through compressing tightly, and seal cover and cylinder body clearance can reach more than the 2mm at the loading and unloading in -process, avoid cylinder body and seal cover to produce extrusion, friction, make the cylinder body loading and unloading convenient, laborsaving, also avoids M5 or the damage of M12 screw hole on the cylinder body simultaneously, and a work efficiency is increased.
Description
Technical field
The utility model relates to railway high speed vehicle Ke Nuoer cylinder body tightness test technical field, is specifically related to a kind of Ke Nuoer cylinder body tightness test cylinder body seal device of tyre.
Background technology
Railway high speed vehicle Ke Nuoer checking cylinder, park cylinder body assembly welding processing after, cylinder body air-tight test need be carried out piece by piece, whether have pore, slag inclusion etc. to affect the defect of checking cylinder assembly braking ability to check cylinder body welding process.Domestic railway high speed vehicle Ke Nuoer checking cylinder, park cylinder body composition air tightness tester cylinder body seal tire, all adopt the sealing of O RunddichtringO or oral area rubber seal structure.During oral area sealing, two M5 or M12 threaded holes at nearly oral area place need add sealing gasket sealing with plug.
Adopt the sealing of O RunddichtringO, during test, the sealing between inboard wall of cylinder block and O type circle seals by the compression deformation of O RunddichtringO adhesive tape.Due to cylinder body composition, all there is annular groove at mouth inner wall place, and like this, cylinder body composition is in process of the test, and during installation and removal, inboard wall of cylinder block and O type circle produce and extrude, rub, and make cylinder body composition load and unload more difficult, greatly, relative efficiency is lower for labour intensity.
When adopting oral area rubber seal, two M5 or M12 threaded holes at the nearly oral area place of cylinder body need add sealing gasket sealing with plug.Because cylinder side wall is thinner, when sealing with plug, easy damaged threaded hole, affects threaded hole precision, time serious, cylinder body can be caused to scrap.
Utility model content
When the employing O RunddichtringO existed to solve prior art seals, the handling of cylinder body composition are more difficult, labour intensity is large, and easy damaged threaded hole during employing oral area rubber seal, cause the technical matters that cylinder body is scrapped, the utility model provides a kind of Ke Nuoer cylinder body tightness test cylinder body seal device of tyre.
The technical scheme that the utility model technical solution problem is taked is as follows:
Gram Nore cylinder body tightness test cylinder body seal device of tyre, it comprises set nut, nut, tension block, pressing plate, sealing shroud, draft tube joint, O RunddichtringO, cylinder locking nut, sealing carcass and tension cylinder; Draft tube joint is fixed on the bottom sides of sealing carcass; Cylinder locking nut is connected with the piston rod thread of tension cylinder, tension block is enclosed within piston rod top, and being supported on cylinder locking nut, the piston rod of tension cylinder, is sealed by O RunddichtringO between tension block and sealing carcass together through the center pit sealing carcass with tension block; Sealing shroud is enclosed within sealing carcass, and pressing plate is enclosed within to be strained on block and sealing carcass and is pressed on sealing shroud, is sealed between pressing plate and tension block by O RunddichtringO; Nut sleeve on tension block, and is pressed on pressing plate; Set nut is pressed on nut after being threaded with tension block.
The beneficial effects of the utility model are: the elasticity utilizing sealing shroud, by compressing bulging by the threaded hole sealing on cylinder body and cylinder body, sealing shroud and cylinder gap are in cargo handling process, more than 2mm can be reached, avoid cylinder body and sealing shroud to produce extruding, rub, make cylinder body easy to loading and unloading, laborsaving, also avoid M5 or M12 threaded hole damage on cylinder body simultaneously; Improve work efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of of the present utility model gram of Nore cylinder body tightness test cylinder body seal device of tyre.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figure 1, of the present utility model gram of Nore cylinder body tightness test cylinder body seal device of tyre comprises set nut 2, nut 3, tension block 4, pressing plate 5, sealing shroud 6, draft tube joint 7, O RunddichtringO 8, cylinder locking nut 9, sealing carcass 10 and tension cylinder 11; Draft tube joint 7 is fixed on the bottom sides of sealing carcass 10; Cylinder locking nut 9 is connected with the piston rod thread of tension cylinder 11, tension block 4 is enclosed within piston rod top, and be supported on cylinder locking nut 9, the piston rod of tension cylinder 11, is sealed by O RunddichtringO 8 between tension block 4 and sealing carcass 10 together through the center pit sealing carcass 10 with tension block 4; Sealing shroud 6 is enclosed within sealing carcass 10, and pressing plate 5 is enclosed within to be strained on block 4 and sealing carcass 10 and is pressed on sealing shroud 6, is sealed between pressing plate 5 and tension block 4 by O RunddichtringO 8; Nut 3 is enclosed within tension block 4, and is pressed on pressing plate 5; Set nut 2 is pressed on nut 3 after being threaded with tension block 4.
During test, workpiece after cylinder body air intake opening is sealed and cylinder body composition 1, be buckled on sealing carcass 10, by the porting 12 on tension cylinder 11, in tension cylinder 11, be filled with pressurized air, make the piston rod of tension cylinder 11 pull pressing plate 5 downward by tension block 4, nut 3, set nut 2, compressing rubber sealing shroud 6, make that sealing shroud 6 is swollen to rise, cylinder body composition 1 is sealed.Then by the cylinder body composition hold-down mechanism on test unit, cylinder body is pressed on sealing carcass 10, utilize elevating mechanism, the cylinder body of tightness test composition 1 and sealed tire device are submerged, again by the draft tube joint 7 on test tire, the inner chamber forming 1 to cylinder body through sealing carcass 10 and the gas passage of tension block 4 is filled with pressurized air, carries out experiments of sealing performance.
