Abstract
A kind of cutting head of laser cutting machine is the utility model is related to stretch sealing device, including corrugated sealing ring, interior guide cylinder, outer guide cylinder, sealing clamping ring, sliding bearing, the outer guide cylinder is covered outside interior guide cylinder, sliding bearing is equipped between outer guide cylinder and interior guide cylinder, the corrugated sealing ring top is wrapped on outer guide cylinder, corrugated sealing ring lower part is wrapped on interior guide cylinder, and the sealing clamping ring is fixed on corrugated sealing ring and interior guide cylinder bottom；When cutting head stretches, gas is in equilibrium state inside cutting head light path with the gas exchanges of corrugated sealing ring in telescopic process so that the gas outside cutting head will not enter in the light path of cutting head, ensure that the purity of gas in the light path of cutting head.The utility model uses corrugated sealing ring, when cutting head stretches, gas is in equilibrium state inside cutting head light path with the gas exchanges of corrugated sealing ring in telescopic process so that the gas outside cutting head will not enter in the light path of cutting head, ensure that the purity of gas in the light path of cutting head.
Description
Technical field
A kind of laser cutting machine is the utility model is related to, especially a kind of cutting head of laser cutting machine, which stretches, seals dress
Put.
Background technology
The cutting head of high power laser cutting machine, it is flexible due to being needed inside cutting head when setting anticollision device, collision-prevention device
Process, it is easy to inside the gas suction cutting head light path outside cutting head light path, since extraneous gas includes impurity, can break
Bad cutting head light path, causes laser cutting to break down.
Utility model content
The utility model aim is to provide a kind of cutting head of laser cutting machine and stretches sealing device, using bellow seal
Circle, when cutting head stretches, gas is in flat inside cutting head light path with the gas exchanges of corrugated sealing ring in telescopic process
Weighing apparatus state so that the gas outside cutting head will not enter in the light path of cutting head, ensure that gas in the light path of cutting head
Purity.
To achieve the above object, the utility model provides following technical solution：
A kind of cutting head of laser cutting machine of the utility model stretches sealing device, including corrugated sealing ring, interior guiding
Cylinder, outer guide cylinder, sealing clamping ring, sliding bearing, the outer guide cylinder is covered outside interior guide cylinder, in outer guide cylinder and interior guide cylinder
Between be equipped with sliding bearing, the corrugated sealing ring top is wrapped on outer guide cylinder, corrugated sealing ring lower part be wrapped in lead
To on cylinder, the sealing clamping ring is fixed on corrugated sealing ring and interior guide cylinder bottom；When cutting head stretches, gas in telescopic process
Body is in equilibrium state inside cutting head light path with the gas exchanges of corrugated sealing ring so that the gas outside cutting head will not
Into in the light path of cutting head, the purity of gas in the light path of cutting head ensure that.
Wherein, the internal diameter on the outer guide cylinder top is less than the internal diameter of outer guide cylinder lower part, including outer guide cylinder top covers
On guide cylinder, outer guide cylinder lower part is sleeved on sliding bearing, and the sliding bearing is along interior guide cylinder when cutting head stretches
Axis direction moves.
Compared with prior art, the beneficial effects of the utility model are：
The utility model uses corrugated sealing ring, and when cutting head stretches, gas is in cutting head light path in telescopic process
The gas exchanges of portion and corrugated sealing ring are in equilibrium state so that the gas outside cutting head will not enter the light path of cutting head
In, it ensure that the purity of gas in the light path of cutting head.

Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
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 embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained, shall fall within the protection scope of the present invention.
Please refer to Fig.1-4：
In the utility model embodiment, the cutting head of laser cutting machine of the utility model a kind of stretches sealing device, bag
Corrugated sealing ring, interior guide cylinder, outer guide cylinder, sealing clamping ring, sliding bearing are included, the outer guide cylinder is covered outside interior guide cylinder,
Sliding bearing is equipped between outer guide cylinder and interior guide cylinder, the corrugated sealing ring top is wrapped on outer guide cylinder, ripple
Sealing ring lower potion is wrapped on interior guide cylinder, and the sealing clamping ring is fixed on corrugated sealing ring and interior guide cylinder bottom；Work as cutting
When head is flexible, gas exchanges of the gas with corrugated sealing ring inside cutting head light path are in equilibrium state in telescopic process, make
Obtaining the gas outside cutting head will not enter in the light path of cutting head, ensure that the purity of gas in the light path of cutting head.
The internal diameter on the outer guide cylinder top is less than the internal diameter of outer guide cylinder lower part, and outer guide cylinder top is covered in interior guide cylinder
On, outer guide cylinder lower part is sleeved on sliding bearing, and the sliding bearing is along the axis side of interior guide cylinder when cutting head stretches
To movement.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of the spirit or essential attributes without departing substantially from the utility model, it can realize that this practicality is new in other specific forms
