When head collides with workpiece, cushion collar is contacted with workpiece, and now cushion collar is sent out by greater impact, hemisphere jut with cushion collar
Raw relative slip, cushion collar move to close to rigid enclosure direction.During cushion collar moves to rigid enclosure, elastic component plays auxiliary
The effect of buffering.After disappearance is impacted, cushion collar resets under the elastic force effect of elastic component itself.
In this programme, nozzle is always positioned in rigid enclosure, is also equipped with cushion collar and elastic component above rigid enclosure, is worked as laser
When cutting head is hit, impulsive force is delivered on cushion collar and is eventually transferred in rigid enclosure, because rigid enclosure is connected with mounting seat,
And nozzle is always positioned in rigid enclosure not contacting with rigid enclosure, therefore nozzle will not be by any impact；Solves traditional laser
When cutting head is hit, impulsive force is delivered to the problem of causing nozzle to damage on nozzle.Other hemisphere jut and cushion collar are a little
Contact, so cooling ring influenceed by cushion collar it is smaller.
Preferred scheme one：Based on scheme preferred scheme：The quantity of the hemisphere jut and groove is four, and
Hemisphere jut is uniformly distributed on the same circumference of cooling ring, makes the strong point of cushion collar more uniform, is reduced cushion collar and is being moved
During rock.
Preferred scheme two：Preferably one preferred scheme：The bottom of the rigid enclosure is embedded with permanent magnet and determined
Position bar.Because mounting seat is typically ferrous material, permanent magnet can facilitate the connection of rigid enclosure and mounting seat, and locating rod realizes rigidity
