Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of guide rail positive pressure protection mechanism, including connection
Plate 1, the side of connecting plate 1 is connected with shield 2, and the other side of connecting plate 1 is connected by bellows 3 with support plate 4,
It is provided with air inlet 10 on connecting plate 1 and support plate 4, and sealing is connected with by connecting shaft 11 in connecting plate 1 and support plate 4
Rubber stopper 12 is connected with mounting rod 5 in support plate 4, and the outside of mounting rod 5 is equipped with filter plate 9, and filter plate 9 is set to logical
One end of gas hose 7, and the other end of steam hose 7 protrudes into U-tube 6 through mounting rod 5, U-tube 6 is connected to mounting rod 5
Lower end, and mounting rod 5, through there is air inlet pipe 8, one end of air inlet pipe 8 is protruded into U-tube 6, and the other end connection of air inlet pipe 8
In in the air inlet 10 in support plate 4.
Air inlet 10 on shield 2 and bellows 3 is distributed with linear type in a ring respectively, and air inlet 10 is most
Large diameter is less than the maximum gauge of sealing rubber plug 12, can quickly enter in shield 2 and bellows 3 convenient for gas, and
The stable sealing air inlet 10 of sealing rubber plug 12 can be passed through.
The longitudinal section area of bellows 3 be greater than shield 2 longitudinal section area, and the both ends of bellows 3 respectively with
4 seamless binding of connecting plate 1 and support plate, can in the case where bellows 3 and shield 2 are compressed and stretch same distance,
Guarantee that the gas that bellows 3 discharges can be bigger than the gas volume that shield 2 needs to absorb, to can guarantee that shield 2 is being pressed
It inside it is always positive pressure under contracting or tensional state.
Mounting rod 5 is connect using the form of plug with filter plate 9, and mounting rod 5 is integrated with support plate 4 and sets
It sets, filter plate 9 can be conveniently replaceable.
It is connected between U-tube 6 and mounting rod 5 using dismountable mode, and mounting rod 5 is arranged perpendicular to support plate 4, energy
It is conveniently replaceable U-tube 6.
The planform of air inlet 10 and sealing rubber plug 12 is truncated cone-shaped, and sealing rubber plug 12 is connected by connecting shaft 11
It is connected in shield 2 and bellows 3, air inlet 10 can be sealed convenient for sealing rubber plug 12, and bellows 3 can be made to compress
When, when only discharging gas into shield 2, and bellows 3 can be made to stretch, only absorb extraneous gas.
The guide rail positive pressure protection mechanism: being mounted on lathe by working principle first, and when in use, shield 2 will be with leading
The use of rail and repeatedly flexible, enter in guide rail to avoid extraneous bulky grain foreign matter, when shield 2 is shunk, inside
It will be in barotropic state, to spray gas, outwardly to avoid the grinding dust and a large amount of water generated during machine tooling
Mist is pumped to inside shield 2, and when shield 2 is shunk, bellows 3 will be drawn under the action of connecting plate 1 and support plate 4
It stretches, so that extraneous gas enters in the liquid in U-tube 6 after the filtering of filter plate 9 from steam hose 7, and by
Air inlet pipe 8 enters in the air inlet 10 in support plate 4, the connecting shaft 11 hence into the inside of bellows 3, on connecting plate 1
With sealing rubber plug 12, when being avoided that shield 2 is shunk, internal gas enters in bellows 3；
In above process, the liquid in U-tube 6 and filter plate 9 can absorb the little particle in ambient atmos, in order to avoid small
Grain enters in bellows 3, influences the service life of bellows 3；
When shield 2 stretches, will need to absorb extraneous gas, and in its stretching, bellows 3 will connect
It is compressed under the action of plate 1 and support plate 4, due to the setting of connecting shaft 11 and sealing rubber plug 12 on connecting plate 1, can to stretch
When contracting hose 3 compresses, internal gas enters in shield 2, and 12 energy of connecting shaft 11 and sealing rubber plug in support plate 4
Its internal gas sprays to the external world when bellows 3 being avoided to compress, and since the longitudinal section area of bellows 3 is greater than shield
2 longitudinal section area, so the gas volume that bellows 3 sprays when compressing is greater than the gas for needing to absorb when shield 2 stretches
Body volume, Gu shield 2 when stretching, inside can still be in barotropic state, and outwardly jet, so that lathe be avoided to add
The grinding dust and a large amount of water mists generated during work is pumped to inside shield 2, and what is be not described in detail in this specification is interior
