But, exist and be difficult while the tension force for the injection pressure for overcoming auxiliary gas is put on into thin plate while thin plate is kept In XY platforms, need proficiency the problem of.
The content of the invention
The problem of present invention is in order to solve above-mentioned and propose, can be with its object is to provide a kind of thin plate holding meanss Thin plate is located on XY platforms by easy operation.
In order to realize the purpose, the thin plate holding meanss recorded according to technical scheme 1 are that the thin plate in laser machine is protected Device is held, the laser machine possesses：Processing head, laser and injection auxiliary gas are irradiated to the thin plate as machined object；With And XY platforms, the planar movement on the direction perpendicular to the optical axis of the laser irradiated from the processing head, be installed with XY platforms across Both set a distance opposed the 1st frame material and the 2nd frame material.The 1st part is equipped between the 1st frame material and the 2nd frame material, by the 1st part One end of grabbing thin plates.Can relatively movably be constituted on the direction left from the 1st part has the 2nd part, the 2nd part edge The 2nd frame material to be disposed between the 1st frame material and the 2nd frame material.By the other end of the 2nd part grabbing thin plates.
The one end for the multiple connecting rods that can be swingingly formed in the face intersected with optical axis connects with multiple positions of the 2nd part Knot, the other end and the tension-applying mechanism of these connecting rods link.The tension-applying mechanism exerts a force to the 2nd part to the 2nd frame material, from And apply tension force to the thin plate that two ends are clamped by the 1st part and the 2nd part, so with can be with easy operation by thin plate Located at the effect of XY platforms.
The thin plate holding meanss recorded according to technical scheme 2, are the thin plate holding meanss in laser machine, the laser adds Work equipment is standby：Processing head, laser and injection auxiliary gas are irradiated to the thin plate as machined object；And XY platforms, perpendicular to Planar movement on the direction of the optical axis of the laser irradiated from the processing head, be installed with XY platforms across both set a distances it is opposed the 1 frame material and the 2nd frame material.The 1st part is equipped between the 1st frame material and the 2nd frame material, by one end of the 1st part grabbing thin plates.Energy Enough relatively movably constituted on the direction left from the 1st part has the 2nd part, and the 2nd part is disposed in the along the 2nd frame material Between 1 frame material and the 2nd frame material.By the other end of the 2nd part grabbing thin plates.
One end of thread-like member links with the 2nd part, and the other end and the 1st part link.The thread-like member is wound in by energy The wheel of the parts of earth's axis Zhi Yu 1 is enough rotated, so the 1st part and the 2nd part can be made in the centre of the 1st frame material and the 2nd frame material Position is relatively moved.The 2nd part is exerted a force to the 2nd frame material by tension-applying mechanism, so as to two ends by the 1st part and the 2nd The thin plate of part clamping applies tension force, therefore has the effect that thin plate can be located to XY platforms with easy operation.
The thin plate holding meanss recorded according to technical scheme 3, are the thin plate holding meanss in laser machine, the laser adds Work equipment is standby：Processing head, laser and injection auxiliary gas are irradiated to the thin plate as machined object；And XY platforms, perpendicular to Planar movement on the direction of the optical axis of the laser irradiated from the processing head, be installed with XY platforms across both set a distances it is opposed the 1 frame material and the 2nd frame material.The 1st part is equipped between the 1st frame material and the 2nd frame material, by one end of the 1st part grabbing thin plates.Energy Enough relatively movably constituted on the direction left from the 1st part has the 2nd part, and the 2nd part is disposed in the along the 2nd frame material Between 1 frame material and the 2nd frame material.By the other end of the 2nd part grabbing thin plates.
Support rod is equipped between the 2nd part and the 1st part, two ends are supported by the 1st part and the 2nd using the support rod The lower surface of the thin plate of part clamping, so can suppress due to deadweight that thin plate is bent downwards.Utilize tension-applying mechanism 2nd part is exerted a force to the 2nd frame material, so as to apply tension force, therefore tool by the thin plate that the 1st part and the 2nd part are clamped to two ends 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.

Then, reference picture 2 illustrates thin plate W holding meanss 10.Fig. 2 is the top view of thin plate W holding meanss 10.This Outside, Fig. 2 eliminates the diagram for the XY platforms 11 for being installed with framework 20.As shown in Fig. 2 holding meanss 10 possess framework 20.Framework 20 It is that can removably be fixedly arranged on the part of XY platforms 11, by the 1st frame material 21 and the 2nd frame material 22 and the 1st frame material 21 and the 2nd of holding The 3rd frame material 23 at the interval of frame material 22 is formed as overlooking the picture frame shape of rectangle.In the medial surface shape in the horizontal direction of the 3rd frame material 23 Into there is guiding element 24.Guiding element 24 is the position for making the 1st part 30 and the 2nd part 40 be slided along the 3rd frame material 23.
1st part 30 and the 2nd part 40 are the parts at the two ends for grabbing thin plates W, respectively with the 1st frame material 21 and the 2nd Frame material 22 is disposed in the inner side of framework 20 substantially in parallel.Supporting member 31,41 is alongst mounting thin plate W end Part, slide unit 31a, 41a chimeric with the guiding element 24 of the 3rd frame material 23 is installed at the two ends of supporting member 31,41. On the upper surface of supporting member 31,41, possess the pressing component 32,42 for pressing thin plate W end from upper surface and make The pressing component 32,42 is to supporting member 31,41 sides（Lower section）Move and grabbing thin plates W fastener 33,43.It is tight by operation Firmware 33,43, can move up and down pressing component 32,42.By making pressing component 32,42 move downwards, it can clamp Thin plate W, is decontroled by being moved upward pressing component 32,42.
Two sides of the 1st part 30 and the 2nd part 40 are linked by the thread-like members such as cable wire, chain 51.One end is locked to the 2nd The thread-like member 51 of part 40 is extended towards the 1st frame material 21, wound on can rotate the wheel 50 of the frame materials 21 of earth's axis Zhi Yu 1 On, the other end is engaged with the 1st part 30.Thus, if sliding a side of the 1st part 30 or the 2nd part 40, the 1st part 30 Or the 2nd the opposing party of part 40 linkedly slided by thread-like member 51.So that the 1st part 30 and the 2nd part 40 can be realized It is located at the length of the 3rd frame material 23 with the 1st frame material 21 and the close state of the 2nd frame material 22 and the 1st part 30 and the 2nd part 40 respectively The mode of the state of direction substantial middle is spent, the length and slide unit 31a, 41a of thread-like member 51 is set relative to guiding element 24 Nested position, therefore, it is possible to which thin plate W to be maintained to the substantial middle of framework 20 by the 1st part 30 and the 2nd part 40.
It is equipped on the 2nd part 40：Tension-applying mechanism 60, to the thin plate clamped by the 1st part 30 and the 2nd part 40 W applies tension force；And mobile limiting mechanism 70, the 2nd part 40 based on the tension-applying mechanism 60 is limited to the side of the 2nd frame material 22 Movement.Tension-applying mechanism 60 possesses：Fastener 61, is locked to the 2nd part 40；The locking is fixed in threaded rod 62, one end Portion 61, another side insertion are arranged at the 2nd frame material 22；And force section 63, pressed by being screwed with the threaded rod 62 The end face outside of 2nd frame material 22, exerts a force to the side of the 2nd frame material 22 to the part 40 of fastener 61 and the 2nd.With respect to framework 20 Width（Fig. 2 above-below directions）The imaginary line in center（It is not shown）A tension force, which is respectively equipped, at symmetrical position applies machine Structure 60.
Mobile limiting mechanism 70 possesses：Pressing portion 71, pushes the 2nd part 40；The pressing portion is fixed in threaded rod 72, one end 71, another side insertion is arranged at the 2nd frame material 22；And fixed part 73, with the threaded rod 72 be screwed so as to the 2nd frame material 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 W。
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 Holding meanss 110 top view.
1st part 130 of holding meanss 110 and the 2nd part 140 possess parallel with the 1st frame material 21 and the 2nd frame material 22 respectively 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 It is upper inclination and furthered to the 2nd frame material 22.Thereby, it is possible to make thin plate W equably be tensioned.
In addition, pressure cylinder 160 is the pneumatic cylinder using air pressure telescopic drive bar 161, it is configured to utilize air pressure And the reciprocating pressure cylinder of the twocouese action in elongation driving and the contraction driving of bar 161.Thus, by discharging pressure cylinder 160 driving pressure（Air discharges）, the driving force applied from pressure cylinder 160 to supporting member 141 can be released.
Connecting member 170 is the part of the frame material 22 of connection support part part 141 and the 2nd, with passing through fastening bolt（It is not shown） The side of supporting member 141 and the bottom surface of the flat stop component 171 prominent to the 2nd frame material 22 is fixedly secured to abut Flat matrix part 172 can be slided with the bottom surface of these stop components 171 and the upper surface of matrix part 172.
Stop component 171 and matrix part 172 are formed as the reciprocally parallel tabular surface in upper surface and bottom surface, these upper tables Face and bottom surface are arranged in the mode parallel with the telescopic direction of pressure cylinder 160.Thus, in supporting member 141 along with pressure cylinder 160 when stretching and moving in parallel, the bottom surface of stop component 171 and the upper surface of matrix part 172 can be slided.
On stop component 171, the telescopic direction with the bar 161 in pressure cylinder 160 is formed through on thickness of slab direction The elongated hole 171a overlooked as Long Circle set is extended parallel to, on matrix part 172, in the elongated hole with stop component 171 At the corresponding positions of 171a, it is formed through and is overlooked as circular axle inserting hole on thickness of slab direction（It is not shown）.Also, On 2 frame materials 22, at position corresponding with the axle inserting hole of matrix part 172, on thickness of slab direction being formed through vertical view is Circular through hole（It is not shown）.Handle portion 173 is threadedly coupled with the top of fastener shaft part 174, and the fastener shaft part 174 is distinguished It is inserted through these elongated holes 171a, through hole（Fig. 4 paper vertical direction）, it is not threaded with revolvably with double nut in lower end The clamp nut portion of function（It is not shown）.
Thus, by rotating handle portion 173, handle portion 173 can be made for the precession of fastener shaft part 174 in fastening Nut portions（2nd frame material 22）Clamped between handle portion 173 and keep stop component 171 and matrix part 172（Below by the state Referred to as " tightening state "）, the frame material 22 of supporting member 141 and the 2nd can be fastened by connecting member 170.That is, thin plate is being carried out It is by the convergent force of pressure cylinder 160 that supporting member 141 is near towards the layback of the 2nd frame material 22 during W cutting off processing, it is thin being formed After the state of the tensioning of the plate W application based on tension force, connecting member 170 is set to turn into fastening shape by the operation of handle portion 173 State, passes through the connection support part part 141 of connecting member 170 and the 2nd frame material 22.Add as a result, can limit and implement cut-out to thin plate W The elongation of thin plate W during work.
Fig. 3 is returned to illustrate.Be equipped with machine table 12 detection the part 130 of machine table 12 and the 1st distance away from From detection means 180.Distance detection device 180 is for detecting the distance until the 1st part 130 and exporting the testing result To control device 13（Reference picture 1）Device, possess range sensor（It is not shown）And by the detection knot of the range sensor Fruit handles and exported to the output loop of control device 13（It is not shown）.Range sensor is following sensors：From internal light Source（LED or laser diode）To the irradiation light of the 1st part 130, and by the light receiving element with inside（It is not shown）Receive by the 1st The reflected light that part 130 reflects is so as to detecting distance.
The part 130 of support rod 181 and the 1st and the 2nd part 140 substantially in parallel, be reciprocally disposed in frame at spaced intervals The inner side of body 20.Support rod 181 is the part for the thin plate W that supporting is kept by the 1st part 130 and the 2nd part 140, support rod 181 Upper end abutted with thin plate W lower surface, thin plate W is supported on to set height and position.It is attached at the two ends of support rod 181 Slide unit 182.Slide unit 182 engages with the medial surface of the 3rd frame material 23, so that support rod 181 can be along the 3rd frame material 23 It is mobile.Slide unit 182 uses elastomeric element（Spring）183 reciprocally link, in the 1st frame material 21 and the 2nd frame material 22 and sliding part Elastomeric element is also used respectively between part 182（Spring）184 link.
In addition, in the specified location of the support rod 181 between the part 130 of machine table 12 and the 1st, cutting and being formed with use The cut-away 181a passed through in the light for making to irradiate from distance detection device 180 to the 1st part 130.Pass through the shape in support rod 181 Into there is cut-away 181a, can realize simultaneously based on distance detection device 180 with the detection of the distance of the 1st part 130 and being based on The thin plate W of support rod 181 supporting.
If keeping thin plate W by the 1st part 130 and the 2nd part 140, thin plate W is by two support rods 181 and machine table 12 supporting lower surfaces.Thus, it can make to produce between the 1st part 130 and the 2nd part 140 and machine table 12 by support rod 181 The raw thin plate W flexure based on deadweight further reduces, and thin plate W can be generally flatly installed on into framework 20.As a result, Even if the tension force applied by pressure cylinder 160 to thin plate W is smaller, optical axis direction downsides of the thin plate W to laser can be also prevented（Figure 3 papers are inboard）Flexure.If the tension force applied to thin plate W can be reduced, the elasticity that thin plate W is kept based on tensioning can be reduced Deflection, and can be using the small pressure cylinder 160 of tensile force.
In addition, when laser cutting is processed, framework 20 is with being based on control device 13（Reference picture 1）Cut-out information XY platforms 11 movement is moved together.Now, if support rod 181 is contacted with machine table 12, support rod 181 is moved by slide unit 182 It is dynamic.Also, if framework 20 is moved round about, support rod 181 returns to original position by elastomeric element 183,184. Therefore, support rod 181 will not turn into the obstruction of Laser Processing.
In the present embodiment, the situation by spring composition elastomeric element 183,184 is illustrated, but might not be limited In this, naturally it is also possible to the formation elastomeric element 183,184 such as rubber.Also, illustrate that slide unit 182 uses elastic portion each other The situation that part 183 links, but it is also possible to link slide unit 182 with rigid bodies such as connecting rods each other, by the 1st frame material 21 and the 2nd Linked between frame material 22 and slide unit 182 with compression spring.Also, by setting up buffer, elastomeric element can be suppressed 183rd, the vibration of 184 support rods 181 caused.
Then, reference picture 5 illustrates the detailed composition of holding meanss 110 to Fig. 7.Fig. 5 is the holding dress of Fig. 3 V-V lines Put 110（2nd part 140）Profile.In addition, illustrating the composition of the 2nd part 140 herein and omitting the description what is similarly constituted 1st part 130.
As shown in figure 5, the 2nd part 140 is configured to possess：Part 142 is accepted, in inner side（On the left of Fig. 5）Formed and load thin Plate W loading surface 142a；Wall portion 142b, erects the rear end side in the loading surface 142a of the undertaking part 142（On the right side of Fig. 5）；Apply 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 The other end of part 145 is abutted with groove 143b bottom surface, and force application part 145 is between supporting member 141 and pressing component 143 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 Axis portion 146a, the axle portion 146a bottom are threadedly coupled with accepting part 142.Head 146b external diameter is set to compare axle portion 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 （Reference picture 6（a））The profile of pressing component 143 and undertaking part 142 during relieving.Such as Fig. 7（b）It is shown, pressing component 143 Press surface 143a be configured to along the relative movement direction of the 2nd part 140（Fig. 3 left and right directions）Left from wall portion 142b 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 Portion 181, control device 13 make laser according to from the presence or absence of incident light of light beam irradiation portion 180 for being disposed in undertaking part 142 The situation that processing machine 1 is acted, but it is not necessarily limited to this, naturally it is also possible to light beam irradiation portion is arranged on pressing component 143 180, and light receiver 181 is arranged on part 142 is accepted.

Then, reference picture 8 illustrates the 3rd embodiment.In the 2nd embodiment, illustrate via connecting rod L pressure cylinders 2nd part 140 is furthered and applies tension force to thin plate W and make the situation of thin plate W equably elastic deformations by 160 to the 2nd frame material 22. In the 3rd embodiment, illustrate in order that thin plate W more uniformly elastic deformation and with the supporting member 231 of the 1st part 230 The situation of cross member 238 is arranged side by side.In addition, being omitted for marking identical symbol with the 2nd embodiment identical part The following description.Fig. 8 is the top view of the holding meanss 210 of the thin plate W in the 3rd embodiment.
Holding meanss 210 are configured to mainly possess：The supporting member 231 that is abreast arranged with the 1st frame material 21, cross member 238（1st part 230）And the 2nd part 240；And the fastener of the upper surface of supporting member 231,141 is disposed in respectively 134th, 144, it is grabbing thin plates W two ends and keeps thin plate W device.
Inner side of the supporting member 231 along the 1st frame material 21 is arranged, and fastening bolt is passed through at two ends（It is not shown）It is fastened and fixed There is moving parts 237, be erected at via moving parts 237 between the 3rd frame material 23.Moving parts 237 is to be disposed in the 3rd frame material 23 Upper surface part, be configured to along formed the 3rd frame material 23 length direction（Fig. 8 left and right directions）On guiding groove （It is not shown）It is mobile, and be configured to be fastened and fixed in the arbitrary position of the 3rd frame material 23 by rotary handle 237a.
Also, supporting member 231 is, in the length direction with respect to the 1st frame material 21 and the 2nd frame material 22（Above and below Fig. 8 Direction）The imaginary line in center（It is not shown）Two positions of symmetrical position, are formed with the 2nd frame material 22 from supporting member 231 Side（On the right side of Fig. 8）Side to the side of the 1st frame material 21（On the left of Fig. 8）Side insertion through hole 231a.
Cross member 238 is erected between the 3rd frame material 23 along supporting member 231, and two ends fastening bolt 240 is fastened and fixed In the side of the 1st frame material 21 of moving parts 237（On the left of Fig. 8）Side.Cross member 238 is, from the supporting member of cross member 238 231 sides（On the right side of Fig. 8）Side to the side of the 1st frame material 21（On the left of Fig. 8）Side be formed through and be formed through in support The through hole 238c of the through hole 231a connections of part 231.Supporting member 231 and cross member 238 are by inserting in through hole 231a, 238c Secure component 239 is fastened and fixed.
Secure component 239, which is matched somebody with somebody, is set to following positions：Connect the restraint location in the supporting member 231 of secure component 239（Figure A shown in 8）, pressure cylinder 160（Support member 162（Reference picture 4））Supporting member 141 in coupling position（Shown in Fig. 8 B）The straight line C of two（Imaginary line）It is parallel.
Thus, pressure cylinder 160 is made（Reference picture 4）When acting and shrinking drive rod 161, supporting member 141 is by the receipts Contracting power is via connecting rod L by the side of the 2nd frame material 22（On the right side of Fig. 4）Further, tension force is applied to thin plate W.Due to supporting member 141 via Two connecting rod L link with pressure cylinder 160, therefore the splint fixation W in the state of somewhat relaxing, and also make supporting member 141 Slided and tilted in the horizontal direction using the guiding element 24 at two ends, thin plate W can be made substantially evenly to be tensioned.
Here, via moving parts 237, two ends are fixed on the situation on the 3rd frame material 23 in supporting member 231（Do not possess The situation of cross member 238）Under, if shrinking driving pressure cylinder 160 and moving the 2nd part 240 and apply tension force to thin plate W, To thin plate W at the end of connection supporting member 231（Moving parts 237）Tensile force is acted on on the incline direction of pressure cylinder 160.By This, especially, thin plate W's distorts ground elastic deformation along near the edge of the 3rd frame material 23.Tension force is being applied with to thin plate W 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.
