Step 5, repetition above step 4-5, until completing whole welding production；

System is closed.

By above-mentioned steps, laser head is constantly in fully loaded working condition after system boot, and production capacity is in maximization shape State.

Describe the structure of the two-way laser weldering various parts and the work of each production stage in detail with reference to diagram Principle.

With reference to Fig. 1, the first steel structure is set on the ground first, the first steel structure has a laser head walking axle and is supported on Laser head walking shaft supporting frame below the laser head walking axle two ends, wherein, laser head walking axle is parallel to the ground, and each swashs Shaven head walking shaft supporting frame include the contour column of two settings perpendicular to the ground and one be erected at two column tops and Crossbeam parallel to the ground, laser head walking axle is secured on this two crossbeams, and the two of each laser head walking shaft supporting frame There is gap between bar column, the gap is used as lower part passage, therefore the gap should be not less than the weldment after welding Width.

Laser head is arranged on laser head walking axle, is configured to along laser head walking axle movement, and laser head is configured to Laser is sent by control device control, therefore its travel path is exactly the formation path of weld seam.

For the ease of describing overall structure, we are provided with two datum levels, wherein, through laser head walking axle Shaft centre line and plane perpendicular to the ground is defined as the first datum level；Arrange in the midpoint of laser head walking axle One datum line, the datum line is vertical with laser head walking axle, parallel to the ground, hangs down through the datum line and with ground Straight plane is defined as the second datum level.

Aforementioned first operational board and the second work table are arranged on laser head walking axle lower section, and both are relative to the second base Quasi- face is symmetrically placed, and the structure of the first work table and the second work table be able to can also be differed with identical, but two works The weld seam formation path for making board is necessarily arranged on immediately below laser head walking axle.

Generally for production process is simplified, also for the maintenance management for being easy to equipment, the first work table and the second work It is identical and symmetrically placed relative to the second datum level that board is configured to structure.First work table is included for by the first weldment The workbench that is stitched together and implements to weld with the contraposition of the second weldment, for the respectively weldment of automatic piece supplying first and the second weldment Two upper part components, and for the lower part component of automatic piece unloading.Workbench is located at immediately below laser head walking axle, on two Part modular construction is identical, and symmetrically placed relative to the first datum level.

As it was previously stated, when laser head moves to the welding of the first work table top, the second work table carries out new round welding Preparation, preparation includes：The weldment that lower part component will complete to weld on the second work table is moved from workbench To lower part hopper, the first weldment, the second weldment are moved to alignment table and are completed by upper part component from the respective upper part hopper being located respectively Pre-determined bit, and make the first weldment and the second weldment complete contraposition splicing on the table.The weldment weldering on the first work table After the completion of connecing, laser head moves at once the second work table top to be continued to weld, and now the first work table continues executing with welding Preparation, so realizes the fully loaded work of laser head, realizes that production capacity maximizes production.

Upper part component is included for depositing the upper part hopper of unwelded weldment, the alignment table for pre-determined bit weldment, being used for Weldment is moved to into the upper part handgrip of alignment table from upper part hopper, for weldment to be grabbed from the fine positioning that alignment table moves to workbench Hand, and for aiding in the second steel structure of upper part handgrip, the movement of fine positioning handgrip.

The second steel structure includes upper part handgrip walking axle column and upper part handgrip walking axle, wherein, handgrip walking axle stands Post is vertically fixed on ground；Upper part handgrip walks axle parallel to ground, and its one end is vertically fixed on the upper part handgrip On walking axle column, the other end is vertically fixed on the laser head walking axle.

Upper part hopper is placed on the ground, is used as placing the weldment for not yet welding, and weldment stacking is placed, upper part hopper four Arrange multiple magnetic week to say good-bye device, make there is space between the weldment that overlap places, reduce the absorption affinity between adjacent weldment.

Because a welding process is related to two kinds of weldments, therefore aforesaid upper part component at least needs to prepare 2 sets, and this two Set upper part component is symmetrically placed in workbench both sides on the basis of the first datum level, concrete size and specification setting with weldment With being defined, such as larger weldment can be with the larger alignment table of usable floor area, upper part hopper and suction bigger upper part handgrip, essence Positioning handgrip.

As a example by two sets, in continuous flow procedure, the weldment on workbench completes to be removed after welding, and distribution is placed on two On alignment table and the good weldment of pre-determined bit is moved at once on workbench and welded, and two upper part handgrips are again respectively from each New weldment is captured from the upper part hopper of side, being transferred to respectively on two alignment tables carries out pre-determined bit, prepare next round weldering Deliver a child product, so as to the utilization rate of laser head, improve production efficiency greatly improved.

In view of the diversity of weldment size, we adjust magnetic and say good-bye the position of device using following two modes.

Say good-bye the mode of device position as a kind of adjustment magnetic, the edge of upper part hopper arranges multiple grooves, each groove Inside it is fixedly installed a guide rail for extending perpendicularly to side corresponding to the groove, magnetic device of saying good-bye is vertically installed at guide rail On, magnetic says good-bye device along guide rail movement, so as to adapt to various sizes of weldment.

Say good-bye as another kind of adjustment magnetic the mode of device position, upper part hopper upper table EDS maps arrange multiple holes, magnetic Property device of saying good-bye be removably mounted in the plurality of hole, by selecting different holes, so that magnetic is said good-bye, device adapts to different The weldment of size.

The bottom of upper part handgrip is provided with some suckers, and the adsorbed state of sucker is adjusted to capture or unclamp by cylinder Weldment.Because weldment is stacked in upper part hopper, in order to upper part handgrip successfully can successively capture weldment, upper part handgrip is set It is set to and can moves up in the side perpendicular to ground；Further, since upper part hopper is usually located at alignment table side, therefore upper part Handgrip is also configured to move in the direction on ground in level, i.e., move horizontally along upper part handgrip walking axle.

Upper part handgrip realizes that level is as follows in the mode that ground direction is moved：

Upper part handgrip walking axle is provided with the first tooth bar on side upward, and upper part handgrip is fixedly mounted on the first bracing frame On, first gear and the first motor are also installed with the first bracing frame, we by first gear by being engaged on the first tooth So that upper part handgrip is arranged on upper part handgrip walking axle, first gear is arranged to the drive in the first motor for mode on bar The tooth bar of dynamic lower edge first is moved, so that upper part handgrip can be along the walking axle movement of upper part handgrip.

Upper part handgrip is realized as follows perpendicular to the mode of ground direction movement：

Aforementioned first bracing frame is by the first connecting plate parallel to the ground and is vertically disposed at first connecting plate one end Second connecting plate is constituted, and upper part handgrip is arranged on the second connecting plate by way of another group of rack and pinion engagement, specifically, It is fixedly installed the second tooth bar on the cantilever of upper part handgrip, the second tooth bar extends perpendicularly to ground, on the second connecting plate Second gear and the second motor for driving second gear are additionally provided with, second gear is engaged on the second tooth bar, the Two Motor drive second gears are rotated, because the first bracing frame is fixed on upper part handgrip walking axle, therefore in relative to force Under effect, the second tooth bar carries upper part handgrip and moves along the direction perpendicular to ground.

Fine positioning handgrip is similar with upper part handgrip along the move mode of upper part handgrip walking axle, but fine positioning handgrip is set Into may only translate, therefore only need to configure a set of motor gear, make the gear that the first tooth bar is engaged on as first gear On, the gear carries fine positioning handgrip along the walking axle translation of upper part handgrip under corresponding Motor drive.

In view of the compactedness of operation, weldment first completes pre-determined bit generally on alignment table, then moves to complete on workbench Into the contraposition with another kind of weldment.In order to complete the pre-determined bit of weldment, we be provided with alignment table two it is mutually perpendicular Groove, is embedded with direct of travel linear pattern drive mechanism parallel to the ground in groove, such as cylinder, linear electric motors, wherein The direct of travel in one linear pattern drive mechanism motion portion is consistent with the direct of travel of laser head, another linear pattern drive mechanism The direct of travel in motion portion is vertical with the direct of travel of laser head, and the fixed part of two linear pattern drive mechanisms is respectively positioned on alignment table Side, does not affect weldment to place, one pushing plate of each self-retaining in the motion portion of two linear pattern drive mechanisms, at the beginning of pushing plate Beginning, position was respectively positioned on alignment table side, and two other side corresponding with pushing plate is provided with baffle plate or alignment pin.Promote Plate is moved in the presence of respective linear pattern drive mechanism, also moves the weldment being placed on alignment table, until weldering Part is adjacent to completely with two baffle plates or alignment pin, and weldment completes pre-determined bit.

Simultaneously as the weldment that pre-determined bit is completed also needs to be shifted on workbench, so alignment table faces with workbench The baffle plate or alignment pin of nearly side is configured to be freely lifted under the driving of cylinder, i.e., pre-determined bit when baffle plate or fixed Position pin rises, and protrudes from alignment table upper surface, and auxiliary weldment is positioned, and after the completion of pre-determined bit, baffle plate or alignment pin are fallen, and hide In alignment table, the lifting that weldment is transplanted on workbench, baffle plate or alignment pin is not affected to be completed by air cylinder driven.In order to ensure Pre- contraposition effect, the alignment table of two upper part components is not configured to concordantly with workbench contact or two parallel sides.

After weldment is aligned in advance completely, next step is that weldment is transferred to into the splicing of the contraposition before being welded on workbench. Due to area of work it is less, in order to not affect the automatic flow of whole welding process, we alignment table and workbench it Between increased a buffer table, thus, welding weldment, welding ends part be located at workbench on, remainder be located at buffer table On, now, alignment table is vacated, and the weldment of next one welding is transferred to alignment table and aligns in advance, prepares next round production.

Weldment is transferred to workbench by alignment table to be completed by fine positioning handgrip, for the ease of description, for upper part first The upper part component of weldment is defined as the first upper part component, and the upper part component for the weldment of upper part second is defined as the second upper part Component, the first upper part component includes the first upper part handgrip walking axle, the first upper part handgrip, the first fine positioning handgrip, the first centering Platform, the second upper part component includes the second upper part handgrip walking axle, the second upper part handgrip, the second fine positioning handgrip, the second alignment table. First fine positioning handgrip is configured to along the walking axle movement of the first upper part handgrip, and the second fine positioning handgrip is configured to along second The walking axle movement of part handgrip.First upper part handgrip walking axle, the second upper part handgrip walking axle are vertically disposed at laser head walking Axle both sides, and the first upper part handgrip walking axle and the second upper part handgrip axle of walking is located on the same line, the straight line and laser Head walking axle square crossing.

Because the first weldment, the second weldment on the first alignment table, the second alignment table complete pre-determined bit respectively, connect Get off to only need to respectively to move to two weldments on workbench by two fine positioning handgrips, allow design welds together two Individual end face just splices immediately below laser head travel path, the laser beam that laser head sends is radiated on end face, completes weldering Connect.

The structure of workbench and fine positioning handgrip is first introduced below：

Workbench is divided into Liang Geban areas, it is assumed that left side for the first half area, right side is the second half area, closes in the first half area The side in the second half area arranges the liftable locating rod of a row, and locating rod arrangement is in alignment, the rectilinear direction and laser Always, the bottom of locating rod is fixed on same connecting rod the direct of travel of head, and connecting rod is hidden in workbench lower section, on connecting rod also A cylinder is connected with, connecting rod is provided under the driving of the cylinder and lifts, and makes the positions stem segment being fixed on connecting rod Protrude from worktable upper surface or be down to completely in workbench.

In order to be completely fixed the weldment placed on the table, we are also provided with the table two row electromagnet, electricity The direct of travel of the orientation uniform laser head of magnet is consistent, and this two row electromagnet is located at respectively the both sides of aforementioned alignment pin, Alignment pin is closed on, before weldment contraposition splicing is completed, electromagnet does not work, after the completion of weldment contraposition splicing, electromagnet is powered and starts, Suction is produced, weldment is tightly adsorbed on the table.

Fine positioning handgrip is similar with upper part handgrip, and its bottom is provided with some suckers, and by cylinder the absorption of sucker is adjusted To capture or unclamp weldment, in addition fine positioning handgrip is also provided with a liftable fixed briquetting to state, and this is fixed Briquetting realizes lifting again by the mode of air cylinder driven, for applying a pressure on weldment, makes weldment be fixed on work On platform, certain lateral thrust can be born and be not subjected to displacement.At least one is equipped with the fixation briquetting in two fine positioning handgrips.

It should be appreciated that fixed briquetting may be used also in addition to applying power or revocation power can be realized in the way of with lifting To realize same purpose by way of upset.

It is briefly described as follows the process that two weldments align on the table splicing, it is assumed that only the second fine positioning handgrip is pacified Fixed briquetting is filled：

Locating rod on workbench is raised up to and partly protrude worktable upper surface；

Second fine positioning handgrip moves to the second alignment table top, captures the second weldment；

The the second fine positioning handgrip for carrying the second weldment moves to workbench top, the end face for making the second weldment to weld It is adjacent to locating rod；

Fixed briquetting on second fine positioning handgrip is fallen, and applies a pressure on the second weldment, consolidates the second weldment Determine on the table；

Locating rod on workbench is fallen to workbench；

First fine positioning handgrip moves to the first alignment table top, captures the first weldment；

The the first fine positioning handgrip for carrying the first weldment moves to workbench top, the end face for making the first weldment to weld It is adjacent to fixed the second weldment on the table；

Electromagnet is powered and starts, and the first weldment, the second weldment are adsorbed on the table, prepares welding.

By above procedure, the alignment pin using rise first makes the second weldment move to setting position, by setting as benchmark Second weldment is fixed on setting position by the fixed briquetting put on the second fine positioning handgrip, then on the basis of the second weldment, will First weldment moves to setting position, completes contraposition splicing, and the first weldment, the second weldment need the end face of welding to be fixed on laser head On travel path.

If two fine positioning handgrips are assembled with fixing briquetting, can fall after contraposition, subsidiary magnet is by two Weldment is fixed on the table, in order to avoid undesirable element is subjected to displacement or can not be adjacent to etc. in process of production.

It should be appreciated that the height of workbench, buffer table, alignment table should be identical, for the ease of weldment movement, we are usual The distribution on alignment table, buffer table arranges some universal rolling wheels, the effect of universal rolling wheel in addition to carrying the weight of weldment, more It is important that assisting weldment movement, the apex height of universal rolling wheel should be consistent, and concordant with worktable upper surface.In view of platform Scuffing in the face of weldment affects, and we can be laying felt on alignment table, buffer table.

Lower part component is included for the interim lower part platform for placing the weldment for completing to weld, for collecting the weldering for completing to weld The lower part hopper of part, the weldment for completing to weld be transferred to the pickup handgrip of lower part platform from workbench, for will be complete Weldment into welding is transferred to the lower part handgrip of lower part hopper, and the 3rd steel for aiding in lower part handgrip to move from lower part platform Structure.

The method of work of the lower part component is as follows：

Weldment on workbench completes welding, moves weldment from workbench after control device control pickup handgrip crawl weldment Deliver to lower part platform；

Pickup handgrip unclamps weldment, and moves to the one end of lower part platform away from workbench；

Lower part handgrip is moved to directly over lower part platform, weldment is moved on to directly over lower part hopper from lower part platform after crawl weldment；
