Blast injection to laser-textured surface is achieved the purpose that cooling by mouth, still, in the process processed to tubing
In due to needing to spray compressed air, larger to the impact of tubing, tubing will receive always jet power in process
And generate bending deformation, and generate deformation force cannot good removal, accumulated in workpiece, influence tubular object extruding precision；Again
Such as patent document 2 (CN207710110U), it discloses the fixture for optical fiber cleaver, which can be to pipe end
It is limited with inner wall, so that clamping tubing carries out cutting work, still, is not considered some tubing such as graphite pipe ratio
It is more fragile, using this kind of fixture meeting of being possible to so that tubing to be processed just occurs broken since clamping dynamics is too big when clamping
It splits；For another example patent document 3 (CN103817443A) is right in the cutting equipment it discloses the laser cutting device of incising pipes

The insertion clamping of different directions；For another example patent document 4 (CN203124967U), it discloses a kind of servo antrol formula round tube laser
Cutting machine, the cutting head of the cutting machine can follow the deformation of tubing and swing adjustment cutting head, but it uses sensing device
14, it 15 is detected, while will test signal and being transmitted in digital control system, to control motor movement, this kind of method is due to needing
Transmit signal, therefore, motor movement generally all have hysteresis quality, be servo-actuated it is ineffective, meanwhile, sensing device is generally used biography
Sensor etc., maintenance cost and price are all more expensive；For another example patent document 5 (CN200988130Y), it discloses a kind of uses
The laser cutting machine of linear motor driving, but both ends of the cutting machine since linear motor to be installed on to rack 1, it should
Cutting machine size is very big, while being provided with many places guide rail, further increases the complexity of equipment；Finally, such as patent document 6
(CN104308209A), it discloses flexible magnet rheological tongs system, which absorbs work using magnetorheological fluid materials
Vibrational energy in part process improves workpiece stress, but its structure is complicated, meanwhile, do not consider the side of being used to support
To vibrational energy absorption.
In conclusion in the prior art, not providing one kind has flexible support fixture, fills specifically for brittleness tubing
Folder, clamping tool can be rotated to be swashed with adapting to different directions clamping tubing while can adapt to the high-precision graphite that tubing vibrates
Light cutting machine.Therefore, designing one kind has flexible support fixture, can rotate specifically for brittleness tubing clamping, clamping tool
Just seem especially heavy with the high-precision graphite laser cutting machine for adapting to different directions clamping tubing while can adapt to tubing vibration
It has wanted.

The lock sleeve workpiece of hunting gear is first inserted in outside graphite tubular member before black pipe fitting, then in step 2 laser head set-up procedure
Afterwards, the laser head lock sleeve of hunting gear is stuck on laser head.
The invention has the advantages that: laser cutting machine is considered in process, since compressed air is carried out to tubing
The exciting caused by tubing in cooling procedure is supported tubing using flexible support, and release tubing is generated due to exciting
Bending deformation, by internal stresses release suffered by tubing, shadow of the periodic perturbations that reduction is generated due to internal stress to machining accuracy
It rings, further increases laser cutting machining accuracy；Including left support locating rack flexible and right support locating rack, pass through judgement
Distance of the laser head (i.e. exciting source) apart from left support locating rack and right support locating rack, laser head from left support locating rack compared with
When close, flexible support, left support locating rack or rigid support, such design will be set as apart from farther away right support locating rack
Mode, it is contemplated that the bending deformation for processing tubing is discharged by selecting the displacement of the support locating rack far from laser head, it can be with
So that the displacement very little of support locating rack can achieve the effect that discharge the bending deformation；In view of for frangible tubing such as graphite
The clamping of tubing, by separately designing the insert configuration inside an insertion tubing and the clamping outside a clamping tubing at both ends
Part structure realizes that tubing clamps jointly, meanwhile, insertion piece is designed as pyramidal structure, pyramidal structure outer end is provided with loading magnetic current
The elastic packaging film for becoming liquid is powered when needing to carry out clamping to different size tubulars, and magnetorheological fluid is become liquid flowing shape
State is inserted into pipe fitting, and so as to adapt to the tubing clamping of different-diameter, in addition the clamping piece structure on one side includes inner cylinder and outer
Cylinder, inner barrel and outer barrel are connected by interlocking bar, when needing the tubing to insertion clamping piece structure to be clamped positioning, pass through drawing
Tensioning line on tight outer cylinder, the tensioning line of tension clamp outer cylinder, and the outer cylinder of clamping is passed to clamping force by interlocking bar
Tubing to be clamped has further ensured the clamping of frangible tubing by such indirect clamping mode；Support rod is rotatably to tie
Structure can first turn to clamping piece structure when needing the tubing processed needs to convey from the station of oriented manipulation person
The direction of oriented manipulation person after being inserted into tubing, in rotation support rod to clamping station, more increases the convenience of operation；Make
