There is the effect that thin plate can be located to XY platforms with easy operation.
The thin plate holding meanss recorded according to technical scheme 4, except any one effect realized of technical scheme 1 to 3
Really, additionally it is possible to which the thin plate with set deformation rate elastic deformation is laser machined, it is smart with the processing that can improve thin plate
The effect of degree.
If that is, Laser Processing when the thin plate that is tensioned be tensioned be released after laser machining, return to the state before tensioning.
If due to application tension force, thin plate is with set deformation rate elastic deformation, by the amendment that deformation rate is multiplied by based on target size
Size is laser machined, and tensioning can be released and thin plate after elastic recovery carries out processing according to target size.
Here, holding meanss are, two ends are fixed in the 3rd frame material of the 1st frame material and the 2nd frame material across both set a distances pair
Put, the two ends of cross member are fixed on the 3rd frame material.The cross member is arranged side by side with the 1st part, and cross member and the 1st part are borrowed
Secure component is helped to be fastened.Thus, after the two ends of thin plate are held on into the 1st part and the 2nd part, if to from the 1st part from
The direction opened relatively moves the 2nd part, then applies tension force to the two ends of thin plate, can make thin plate elastic with set deformation rate
Deformation, and be tensioned.As a result, the thin plate distortion ground elastic deformation after tensioning can be prevented, it can be made with set change
Form quotient elastic deformation, therefore laser machined by being multiplied by the amendment size of deformation rate based on target size, it can open
The processing according to target size is carried out on thin plate after being tightly released.Thus, the effect with the machining accuracy that can improve thin plate
Really.
The thin plate holding meanss recorded according to technical scheme 5, secure component and tension-applying mechanism be disposed in the 1st part and
Multiple positions of 2nd part and with being set to following positions:The restraint location and tension force connected in the 1st part of secure component applies
Multiple straight line parallels of coupling position in 2nd part of mechanism.Thus, opened if applying by tension-applying mechanism to thin plate
Power, then can be along the parallel direction of connection secure component and tension-applying mechanism to thin plate active force.As a result, except technical side
The effect of case 4, also with the effect of machining accuracy can be improved.
The thin plate holding meanss recorded according to technical scheme 6, cross member is in the plane residing for the 1st part and the 2nd part
The side left from the 2nd part of the 1st part is disposed side by side on, therefore relative to the side of the power acted on when being tensioned thin plate
To the rigidity increase of the 1st part and cross member can be made.
Also, the direction of the power by making to act on when being tensioned thin plate is consistent with the axis of secure component, can prevent
Bending stress is acted on to secure component and makes the rigidity increase of the 1st part and cross member.These as a result, it is possible to suppress the 1st
Part and cross member deformation, can put on thin plate by even tension.As a result, except the effect of technical scheme 5, also with energy
Enough improve the effect of machining accuracy.
The thin plate holding meanss recorded according to technical scheme 7, load thin on the loading surface in the 1st part and the 2nd part portion
Plate.The thin plate being loaded in by the wall portion limitation erected respectively in the 1st frame material side and the 2nd frame material side on loading surface is moved.The 2nd
Part is into the state before the direction relative movement left from the 1st part, and the distance between the bottom of wall portion is set to compare thin plate
Dimensional tolerance maximum it is big, even if therefore the size of thin plate changed in the range of tolerance to maximum side, can also prevent
The end for the thin plate being only loaded on loading surface is touched with wall portion.Thereby, it is possible between the 1st clamping part and the 2nd clamping part with
Loose mode grabbing thin plates are not produced on thin plate, by being tensioned thin plate, can stably apply abundance to thin plate and open
Power.Thus, except the effect of any one of technical scheme 1 to 3, also with the effect of machining accuracy can be improved.
The thin plate holding meanss recorded according to technical scheme 8, are connected with the upper end of the 1st part and the wall portion of the 2nd part and set
Epimere portion and the loading surface put are formed as step-like, and a side of force application part is disposed in the epimere portion.Along the length of loading surface
The opposed pressing component in degree direction is up exerted a force by force application part and separates set interval with loading surface, therefore, it is possible to will be thin
Plate inserts the gap.
Also, a side of force application part is arranged in the epimere portion for being formed as step-like with loading surface by wall portion,
When therefore inserting thin plate between loading surface and pressing component, thin plate is hindered by wall portion and can not reach force application part.Thus, energy
Enough prevent that force application part from touching with the end of thin plate and damages.Also, by the active force for making pressing component overcome force application part
And the fastener declined, the press surface of pressing component is pressed to the thin plate for being loaded into loading surface, therefore, it is possible to keep thin plate.
Also, the press surface of pressing component is formed as than thin in the direction in the relative movement direction of the 2nd part
The width of plate is long, therefore, it is possible to press the width entirety of thin plate with single pressing component.As a result, except technical scheme 7
Effect, can also improve and add with the elastic deformation amount's generation deviation for preventing the thin plate in the whole length direction of pressing component
The effect of work precision.
The thin plate holding meanss recorded according to technical scheme 9, the upper side of wall portion is respectively relative to the lateral processing head in bottom
Direction protrude, so the top of thin plate between insertion loading surface and press surface contacts with wall portion and taken in loading surface,
The situation of wall portion can be prevented from crossing.Thus, except the effect of technical scheme 8, also with can prevent by loading surface and pressing
The effect that the thin plate that face is clamped is bent at wall portion.
The thin plate holding meanss recorded according to technical scheme 10, overcome the active force based on tension-applying mechanism, by shifting
Dynamic limiting mechanism limits relative movement of the 2nd part relative to the 1st part, and cutting off processing is implemented to thin plate therefore, it is possible to limit
During thin plate elongation.
That is, Laser Processing when, with cutting off processing is implemented to thin plate, the sectional area of thin plate diminishes.If being applied based on tension force
The active force of mechanism is fixed, then diminishes with the sectional area of thin plate, stress increase, in the feelings without mobile limiting mechanism
The elongation increase of condition lower thin sheet.So, the machining accuracy reduction of thin plate.
On the other hand, relative movement of the 2nd part relative to the 1st part is limited by using mobile limiting mechanism, even if
To thin plate implementation cutting off processing, the sectional area of thin plate diminishes, and can also be tensioned the elongation for keeping thin plate and limiting thin plate.By
This, except the effect of any one of technical scheme 1 to 3, also with the effect of machining accuracy can be improved.

22 inner side end is abutted, and fixes the interval of the 2nd part 40 and the 2nd frame material 22.
Then, the application method of holding meanss 10 constituted as described above is illustrated.Thin plate W using being cut to necessity in advance
The thin plate of minimum size.Thin plate W can be carried out to the installation of framework 20 in the state of framework 20 to be installed on to XY platforms 11.This
Outside, because framework 20 can be dismounted relative to XY platforms 11, thus framework 20 can also be pulled down from XY platforms 11 and in its elsewhere(As long as
It is flat face, everywhere can be with)Thin plate W is installed to framework 20.If also, prepare multiple frameworks 20, can be from XY platforms
11 have unloaded to open respectively in advance in the state of framework 20 and set thin plate W.If being opened in advance to multiple frameworks 20 and setting thin plate W, it can lead to
Cross the Laser Processing changed the framework 20 for being fixedly arranged on XY platforms 11 and thin plate W is carried out to each framework 20.
In order to which thin plate W is installed to framework 20, first, rotation force section 63 and fixed part 73 and the part that unscrews turn into
The state that 2nd part 40 can be relatively moved relative to the 1st part 30.Then, the 1st part 30 and the 2nd part 40 and thin plate W are made
Length(Fig. 2 left and right directions sizes)Accordingly move.Fastener 33,43 is operated, so as in supporting member 31,41 and pressing
Gap is formed between part 32,42, is then inserted a thin plate W side in the gap of supporting member 31 and pressing component 32, so
Fastener 33 is operated afterwards, with supporting member 31 and the grabbing thin plates W of pressing component 32.Then, thin plate W another side is inserted into branch
The gap of bearing portion part 41 and pressing component 42, then operates fastener 43, with supporting member 41 and the grabbing thin plates of pressing component 42

Then, operate(Rotation)Force section 63, fastener 61 is furthered to the 2nd frame material 22.Thus, the 2nd part 40 to the 2nd
The side of frame material 22 is furthered, and holding thin plate W is tensioned by the 1st part 30 and the 2nd part 40.Then, fixed part 73 is operated, makes pressing portion
71 abut with the end face outside of the 2nd part 40, fix the interval of the 2nd part 40 and the 2nd frame material 22.Hereafter, laser cutting is carried out
Processing.After laser cutting process finishing, force section 63 is operated, thin plate W tensioning is released, fastener 33,43 is then operated, released
By supporting member 31,41 and pressing component 32,42 grabbing thin plates W state, the thin plate W after process finishing is unloaded.
According to the thin plate W constituted as described above the part 30 of holding meanss the 10, the 1st and the 2nd part 40 by wound on axle
The thread-like member 51 being supported on the wheel 50 of the 1st frame material 21 links, if so make the 2nd part 40 towards the side of the 2nd frame material 22 move,
Then with this linkedly the 1st part 30 moved to the side of the 1st frame material 21, the interval of the 1st part 30 and the 2nd part 40 broadens.If also,
Make the 2nd part 40 to the side of the 1st frame material 21 move, then with this linkedly the 1st part 30 to the side of the 2nd frame material 22 move, the 1st part 30
And the 2nd part 40 narrower intervals.Thereby, it is possible to make the 1st part 30 and the 2nd part 40 in the 1st frame material 21 and the 2nd frame material 22
Centre position is relatively moved, and substantial middle that can be by holding meanss 10 in framework 20 keeps thin plate W.If as a result, setting
For processing head 4(Reference picture 1)Optical axis be located at framework W center, then can with the focal point of laser be located at thin plate W(Material)'s
The mode of approximate centre keeps thin plate W.Thus, it is easy to implement Laser Processing centered on thin plate W central portion.
Also, tension-applying mechanism 60 is disposed in the width with respect to framework 20(Fig. 2 above-below directions)Center
Imaginary line(It is not shown)Symmetrical position, as long as so in the 1st part 30 and the length direction of the 2nd part 40(Fig. 2 upper and lowers
To)Center keeps thin plate W, it becomes possible to substantially evenly apply tension force on thin plate W width.
Also, in the state of fixed tension force is applied to thin plate W by tension-applying mechanism 60, cut with laser is implemented
Break and process and thin plate W sectional area diminishes, stress becomes big, therefore work in-process thin plate W elongation(Elastic deformation amount)Become big.
Now, corresponding to thin plate W elongation, and in control device 13(Reference picture 1)In the cut-out data that have preset produce it is poor,
Machining accuracy is reduced.On the other hand, holding meanss 10 possess mobile limiting mechanism 70, so the thin plate W in processing can be limited
Extension.Thereby, it is possible to prevent that work in-process thin plate W elastic deformation amount from changing and machining accuracy is reduced.
Also, applying fixed tension force to thin plate W by tension-applying mechanism 60, in Laser Processing on thin plate W
When producing extension, it is possible to also apply tensile force to thread-like member 51.If drawing the state for applying stretch to continue thread-like member 51
Must be long, then there is the danger that thread-like member 51 extends or deteriorated.On the other hand, holding meanss 10 possess mobile limiting mechanism 70,
Therefore, it is possible to suppress the tensile force applied in Laser Processing to thread-like member 51.Extend as a result, thread-like member 51 can be suppressed
Or deterioration.
Then, reference picture 3 illustrates the 2nd embodiment.In the 1st embodiment, the 1st part 30 and the 2nd part are illustrated
40 holding meanss 10 that reciprocally can be linkedly moved by thread-like member 51.On the other hand, in the 2nd embodiment, say
The holding meanss 110 that bright 1st part 130 and the 2nd part 140 can be moved separately.In addition, the 1st embodiment of substitution
In holding meanss 10, in laser machine 1 arrange holding meanss 110.Also, in the 2nd embodiment, for the 1st
Embodiment identical part is labelled with identical symbol and omits the following description.Fig. 3 is the thin plate W in the 2nd embodiment

The supporting member 131,141 that ground is arranged.Supporting member 131,141 is erected between the 3rd frame material 23 along the inner side of the 1st frame material 21,
It is fastened and fixed relative to these the 3rd frame materials 23 by fastening bolt 131a.In addition, on the 3rd frame material 23, along its length side
To(Fig. 3 left and right directions)Fastener hole is formed with every predetermined distance(It is not shown), supporting member 131 is fixed on corresponding to thin plate W
Size position.Along the inner side of the 2nd frame material 22, supporting member 141, its length direction both ends are set(Fig. 3 above-below directions
End)Being capable of left and right directions forwards, backwards(Fig. 3 directions up and down)Slidably it is held in the guide surface of guiding element 24(It is not shown).
1st part 130 and the 2nd part 140 possess:The undertaking part 132,142 of elongated tabular(Reference picture 4), along
The edge of the upper surface of supporting member 131,141 is arranged;Pressing component 133,143, is disposed in and accepts the upper of part 132,142
Portion;And fastener 134,144, pressing force is applied to the pressing component 133,143.On supporting member 131,141, relative
In the width by framework 20(Fig. 3 above-below directions)The imaginary line in center(It is not shown)On symmetrical position, arrange respectively
There are four fasteners 134,144.
Also, via connecting rod L and the pressure for being installed on the 2nd frame material 22 on the side of the side of the 2nd frame material 22 of supporting member 141
Power cylinder 160 links.Also, the frame material 22 of supporting member 141 and the 2nd is linked by connecting member 170.In addition, attached in the 3rd frame material 23
Near position, in the width with respect to framework 20(Fig. 3 above-below directions)The imaginary line in center(It is not shown)Symmetrically
At position, a pressure cylinder 160 is respectively equipped.Than pressure cylinder 160 be located at framework 20 width on the inside of position at,
Relative to being respectively equipped with a connecting member 170 at the symmetrical position of imaginary line.
Then, reference picture 4 illustrates the detailed composition near supporting member 141.Fig. 4 is to maintain the partial enlargement of device 110
Top view.As shown in figure 4, pressure cylinder 160 is installed on the 2nd frame material 22 with bar 161 towards the state of the side of supporting member 141, in bar
161 top, swingingly can be combined with a connecting rod L side by pin.On the other hand, it can be put in connecting rod L another side
Dynamic ground pin is combined with the support member 162 for the side for being fastened and fixed to supporting member 141.
Thus, when the pressure cylinder 160 is acted and is shunk drive rod 161, supporting member 141 is by the convergent force via even
Bar L is by the side of pressure cylinder 160(On the right side of Fig. 4)Further, tension force is applied to thin plate W.It is tensioned thereby, it is possible to which thin plate W to be made to it
State is held in framework 20(Reference picture 3).Also, now, the length direction both ends direction of supporting member 141 is square all around
To can slidably be held in the guide surface of guiding element 24, and supporting member 141 is via two connecting rod L(Reference picture 3)With pressure
Cylinder 160 links, therefore, though with somewhat loose state splint fixation W, supporting member 141 also by connecting rod L in the horizontal direction

Power part 145, a side, which is fixed on, to be connected with wall portion 142b upper end and is formed as step-like epimere with loading surface 142a
Portion 142c;And pressing component 143, it is fixed(Abut)The another side of the force application part 145 and exerted a force upwards, and with loading
Face 142a separates set compartment of terrain, the length direction along loading surface 142a(Fig. 5 paper vertical direction)It is opposite.
Accept the inner side that part 142 is fixed on the upper surface of supporting member 141 by bolt etc.(On the left of Fig. 5)Edge is attached
Closely, loading surface 142a entirely accept part 142 length direction in formed must be than thin plate W width(Fig. 3 above-below directions)It is long.
On loading surface 142a, groove portion 142a1 is formed with the way of as male and fomale(M&F) in whole length direction.In loading surface 142a
Medial end, up protrusion is provided with the convex portion 142d that is formed as ridge shape in whole length direction.
Wall portion 142b is accepting the whole length direction of part 142(Fig. 5 paper vertical direction)Neutrality is located at loading surface
142a rear end side(On the right side of Fig. 5), be formed as top and compare bottom(On the downside of Fig. 5)To inner side(On the left of Fig. 5)It is prominent.Due to wall portion
142b top is protruded than bottom, therefore the insertion thin plate W between loading surface 142a and the press surface 143a of pressing component 143
When, it can prevent the top for the thin plate W being inserted into from crossing wall portion 142b.If in addition, thin plate W crosses wall portion 142b, will press
Part 143 is to when accepting part 142 and pressing, the thin plate W top warpage at wall portion 142b and epimere portion 142c.To thin plate W's
Laser Processing, sometimes after a thin plate W surface irradiation laser is cut off, overturns thin plate W and sets text with laser incising in opposing face
Word etc., if thin plate W top bending, the clamping of the thin plate W after upset becomes difficult, it is therefore desirable to prevent this case.
Epimere portion 142c is to be connected with wall portion 142b upper end and be formed as step-like position with loading surface 142a,
Accept the two ends of part 142(Fig. 3 above-below directions)At neighbouring two, from epimere portion 142c upper surface to undertaking part 142
Bottom surface has been formed through through hole 142e.Force application part 145 is formed by collapse coil spring, from a side insert through hole 142e and
Compressed between the upper surface of supporting member 141 and the lower surface of pressing component 143.Borrowed because force application part 145 is incorporated in
Help wall portion 142b and be formed as with loading surface 142a in step-like epimere portion 142c, therefore when accepting part 142 and pressing
When inserting thin plate W between part 143, thin plate W is hindered by wall portion 142b and can not reach force application part 145.Thereby, it is possible to prevent
Force application part 145 is touched and damaged with thin plate W end.
Pressing component 143 is formed with the groove for storing the epimere portion 142c for accepting part 142 in whole length direction
143b.Groove 143b is formed on pressing component 143, the epimere portion 142c for accepting part 142 is incorporated in this.Therefore, it is possible to
Prevent pressing component 143 relative to undertaking part 142 in width(Fig. 5 left and right directions)Middle position skew.Also, force section

By compression so as to which pressing component 143 is exerted a force upwards.In this wise, pressing component 143 is exerted a force upwards by force application part 145,
Therefore, it is possible to pre-set gap between loading surface 142a and press surface 143a.When keeping thin plate W with holding meanss 110,
First, thin plate W is inserted into the gap, therefore, it is possible to easily be operated.
Than groove 143b in the inner part(On the left of Fig. 5), press surface 143a is formed in whole length direction.Press surface 143a
It is the position for the loading surface 142a pressings for being accepted part 142, is formed in whole length direction in the way of as male and fomale(M&F)
There is groove portion 143a1.Due to being formed with groove portion 143a1,142a1 on press surface 143a and loading surface 142a, therefore, it is possible to increase
These faces and thin plate W frictional resistance in grabbing thin plates W.As a result, suppressing shrinking driving pressure cylinder 160(Reference picture 3 and figure
4)And when making thin plate W tensionings, the thin plate W of tensioning is slipped between press surface 143a and loading surface 142a.
The length of press surface 143a length direction is formed must be than perpendicular to the relative movement direction of supporting member 141(Fig. 3
Left and right directions)Direction in thin plate W width it is long(Reference picture 3 and Fig. 4).Thereby, it is possible to not producing warpage on thin plate W
It is clamped between the press surface 143a of pressing component 143 and the loading surface 142a for accepting part 142.As a result, can prevent
Only thin plate W elastic deformation amount produces inequality in the whole length direction for accepting part 142, it is possible to increase machining accuracy.
The length that the length of press surface 143a width forms width that must be than loading surface 142a is small.Thus,
After thin plate W is loaded on the loading surface 142a for accepting part 142, if the press surface 143a of pressing component 143 is pressed to thin plate W
Pressure, then as shown in figure 5, thin plate W with to loading surface 142a inner side protrude setting convex portion 142d contact, from convex portion 142d to by
Pressure surface 143a is tilted.Thus, in driving pressure cylinder 160(Reference picture 3 and Fig. 4)And when making thin plate W tensionings, point of the power of the tensioning
Power acts on press surface 143a and loading surface 142a.As a result, can further increase frictional resistance, therefore, it is possible to suppress tensioning
Thin plate W slide and between press surface 143a and loading surface 142a depart from.
Limiting unit 146 is the part for the amount of movement upward of pressing component 143 that limitation is exerted a force upwards, be disposed in by
The two ends of splenium part 143(Fig. 3 above-below directions)At neighbouring two.In the present embodiment, limiting unit 146 is by possessing axle portion 146a
Formed, be formed through in the thickness direction of pressing component 143 with head 146b bolt(Fig. 5 above-below directions)Through hole in insert

The internal diameter of the through hole for the pressing component 143 that 146a is inserted is big, from the upper surface of supporting member 141 to head 146b lower surface
Height be set to the height that the upper surface of the pressing component 143 exerted a force is abutted.As a result, passing through pressing component 143
Upper surface abutted with head 146b lower surface, limit the shifting in the direction further up of pressing component 143 exerted a force
It is dynamic.
Then, reference picture 6 illustrates the fastener of the 2nd part 140.Fig. 6(a)It is the holding meanss 110 of Fig. 4 line VI -- VI
(2nd part 140)Profile, Fig. 6(b)It is the enlarged fragmentary cross section for accepting part 142 and pressing component 143.In addition,
Fig. 6(a)In, eliminate the record for the support member 162 that can be seen on the right side of supporting member 141 and handle 144e length
The diagram of the part in direction.
Such as Fig. 6(a)Shown, the 2nd part 140 possesses in the outside of the upper surface of supporting member 141(Fig. 6(a)Right side)Edge
Portion is nearby by the fixed fastener 144 such as bolt.In fastener 144, to be formed at pressing component 143 press surface 143a it is upper
The press body 144a that portion is pressed is installed on connecting rod 144b, and connecting rod 144b is by pin 144d and is fixed on supporting member 141
Upper surface bracket 144c link.Also, handle 144e links by pin 144f and connecting rod 144b, and via connecting rod 144g
Link by pin 144h and bracket 144c.
Because fastener 144 is constituted as described above, if so depression of handle 144e, such as Fig. 6(a)It is shown, plus
The thin plate W that laminate 144a is pressed between pressing component 143, insertion loading surface 142a and press surface 143a is clamped.And if, inciting somebody to action
Handle 144e is lifted upward, then connecting rod 144b is with Fig. 6(a)In turn clockwise, press body 144a is moved upward, therefore is pressed
Splenium part 143 is because based on force application part 145(Reference picture 5)Active force and rise, in loading surface 142a and press surface 143a
Form gap.As a result, in order to which thin plate W will be made to be clamped between loading surface 142a and press surface 143a, can insert therebetween
Thin plate W.
Here, in order to accept grabbing thin plates W between part 142 and pressing component 143, first, the 2nd part 140 to
From the 1st part 130(Reference picture 3)State before the direction relative movement left(Pressure cylinder 160 is set to extend and make the 2nd part 140
The close state with the distance of the 1st part 130)Under, thin plate W is inserted between loading surface 142a and press surface 143a.Now, stand
Located at the wall portion of the undertaking part 132 of the 1st part 130(It is not shown)Bottom and be erected on the carrier of the 2nd part 140
The wall portion 142b of part 142 bottom apart from D(Reference picture 6(b))It is set to the size than thin plate W(Length)The maximum of tolerance
Value is big.Therefore, even if thin plate W size is in tolerance(± 3mm or so)In the range of to maximum side change, can also prevent
The end for accepting the thin plate W inserted between part 142 and pressing component 143 is touched with wall portion 142b.
, can be by making thereby, it is possible to not produce loosely grabbing thin plates W between the 1st part 130 and the 2nd part 140
Thin plate W is tensioned and thin plate W is stably applied the tension force of abundance.Thereby, it is possible to prevent elastic deformation amount because applying to thin plate W
Tension force changes as each thin plate W changes.Thereby, it is possible to improve the machining accuracy by laser.
Then, reference picture 7(a)Illustrate light beam irradiation portion 180.Fig. 7(a)It is the holding meanss of Fig. 4 VIIa-VIIa lines
110(2nd part 140)Profile.Such as Fig. 7(a)Shown, the 2nd part 140 is being accepted the loading surface 142a of part 142 and pressed
On the undertaking part 142 and pressing component 143 at position overlapping above and below the press surface 143a of splenium part 143, it has been formed through
Open-work 140a, 140b of lower connection.
Open-work 140a, 140b are respectively formed in the side remote from wall portion 142b for accepting part 142 and pressing component 143
(On the left of Fig. 7)Clamping boundary line position.If the end that clamping boundary line is the thin plate W for representing insertion exceedes clamping boundary line
And in wall portion 142b sides, then when being tensioned thin plate W also can between loading surface 142a and press surface 143a grabbing thin plates W
The line on border.On the other hand, if the thin plate W of insertion end is not above clamping boundary line, even by loading surface 142a and press
The area for the thin plate W that pressure surface 143a is clamped narrows, it is likely that when being tensioned thin plate W, thin plate W is from loading surface 142a and pressing
The problem of departing between the 143a of face.
In the present embodiment, in the open-work 140a for accepting part 142a is formed at, it is accommodated with towards the saturating of the opposing party
The light beam irradiation portion 180 of hole 140b illumination beams, in the open-work 140b of pressing component 143 is formed at, is accommodated with and receives to saturating
The light receiver 181 of light beam incident hole 140b.Light receiver 181 returns the input and output of the presence or absence of beam detection via cable C
Road(It is not shown), the testing result handles and exported to control device 13 by output loop(Reference picture 1).In control device 13
In, when light receiver 181 detects light beam, it is judged as by loading surface 142a and press surface 143a the thin plate W clamped area
It is narrow, produce the danger that thin plate W departs between loading surface 142a and press surface 143a when being tensioned thin plate W.In order to prevent this
One problem, carries out the report to operator based on warning tones etc., makes the action of laser machine 1 and turns into holding state.
On the other hand, when light receiver 181 does not detect light beam, it is judged as that the thin plate W of insertion exceedes clamping boundary line
(Open-work 140a, 140b position), therefore make pressure cylinder 160(Reference picture 3)Drive and be tensioned thin plate W, continue to laser machine.
Thin plate W size in short-term, based on accept part 142 loading surface 142a and pressing component 143 press surface 143a thin plate W
Clamping and tensioning become insufficient, the bad or machining accuracy reduction that thin plate W departs from is produced sometimes.But, due to laser plus
Work machine 1 possesses light beam irradiation portion 180, can differentiate whether thin plate W size is short before Laser Processing, therefore, it is possible to prevent from not having
The size for noticing thin plate W is short and bad and machining accuracy reduction caused by being processed.
Then, reference picture 7(b)Illustrate pressing component 143 and accept the shape of part 142.Fig. 7(b)It is by fastener 144

Close direction is tilted with the loading surface 142a of undertaking part 142.
Thus, if using fastener 144 after thin plate W is loaded on loading surface 142a(Reference picture 6(a))Make press section
Part 143 declines, then press surface 143b inner side first(Fig. 7(b)Left side)Contacted with thin plate W, with pressing component 143
Drop, press surface 143a and thin plate W contact area little by little broaden.Therefore, if press surface 143a outside(Fig. 7(b)Right side)
Compare, thin plate W is oppressed in inner side strongly.Make pressure cylinder 160(Reference picture 3)Shrink and make the 2nd part 140 and the 1st part 130
Leave, then press surface 143a inside edge is absorbed in thin plate W power and worked, push thin plate W.As a result, tensioning can be prevented
Thin plate W slided between part 142 and pressing component 143 accepting, tensile force, energy can be applied with not losing to thin plate W
It is enough to make thin plate W elastic deformations in the state of controlled.As a result, machining accuracy can be improved.
In addition, in the 2nd embodiment, illustrating to store light-receiving in the open-work 140b for being formed at pressing component 143

Implement Laser Processing under state, tensioning is released after Laser Processing, therefore thin plate W returns to the state before tensioning.If due to applying
Tension force and thin plate W are with set deformation rate equably elastic deformation, then by being multiplied by the amendment chi of deformation rate based on target size
Little progress row is laser machined, and can be released in tensioning and the processing according to target size is carried out on the thin plate W after elastic recovery.
On the other hand, due to connecting the end of supporting member 231 in thin plate W(Moving parts 237)With inclining for pressure cylinder 160
The deformation rate near tensile force, thin plate W edge near distortion ground elastic deformation, therefore edge is acted on tilted direction to be become not advise
Then, therefore, it is difficult to calculate correct amendment size.It is thus impossible to which the enough processing implemented to thin plate W according to target size, sometimes thin
Machining accuracy reduction near plate W machining accuracy, particularly edge.
