Step 5 repeats above step 4-5, until completing entire welding production；

System is closed.

Through the above steps, laser head is constantly in fully loaded working condition after system boot, and production capacity, which is in, maximizes shape State.

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

In conjunction with 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 both ends, wherein laser head walking axle is parallel to the ground, each to swash 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 are secured on this two crossbeams, and the two of each laser head walking shaft supporting frame There are gap between column, which is used as lower part channel, therefore the gap should be not less than the weldment after welding Width.

Laser head is mounted in laser head walking axle, is configured to move along laser head walking axle, laser head is configured to It is controlled by control device and issues laser, therefore its travel path is exactly the formation path of weld seam.

Overall structure for ease of description, we are provided with two datum levels, wherein across the laser head walking axle Shaft centre line and plane perpendicular to the ground is defined as the first datum level；It is arranged in the midpoint of the laser head walking axle One reference line, the reference line is vertical with the laser head walking axle, parallel to the ground, passes through the reference line and hangs down with ground Straight plane is defined as the second datum level.

Aforementioned first operational board and the second work table are arranged below laser head walking axle, and the two is relative to the second base Quasi- face is symmetrically placed, and the structure of the first work table and the second work table can be identical or not identical, but two works The weld seam for making board forms path and is necessarily arranged in immediately below laser head walking axle.

Generally for production process is simplified, also for the maintenance management for being convenient for 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 includes for by the first weldment It is stitched together with the contraposition of the second weldment and implements the workbench of welding, for distinguishing the first weldment of automatic piece supplying and the second weldment Two piece uploading components, and the lower part component for 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 previously mentioned, the second work table carries out a new round welding when laser head moves to welding above the first work table Preparation, preparation include: lower part component will completed on the second work table welding weldment from workbench move To lower part hopper, the first weldment, the second weldment are moved to alignment table from the piece uploading hopper at respective place and completed by piece uploading component respectively Pre-determined bit, and the first weldment and the second weldment is made to complete contraposition splicing on the table.Weldment welds on the first work table After the completion of connecing, laser head, which is moved at once above the second work table, to be continued to weld, and the first work table continues to execute welding at this time Preparation so realizes the fully loaded work of laser head, realizes that production capacity maximizes production.

Piece uploading component includes for storing the piece uploading hopper of unwelded weldment, the alignment table for being pre-positioned weldment, being used for Weldment is moved into the piece uploading handgrip of alignment table from piece uploading hopper, is used to grab weldment from the fine positioning that alignment table moves to workbench Hand, and the second steel structure for assisting piece uploading handgrip, fine positioning handgrip mobile.

The second steel structure includes piece uploading handgrip walking axle column and piece uploading handgrip walking axle, wherein handgrip walking axle is vertical Column is vertically fixed on ground；Piece uploading handgrip walking axle is parallel to ground, and one end is vertically fixed on the piece uploading handgrip On walking axle column, the other end is vertically fixed in the laser head walking axle.

Piece uploading hopper is placed on the ground, and is used as placing the weldment not yet welded, weldment, which stacks, to be placed, piece uploading hopper four Multiple magnetism are arranged week to say good-bye device, has gap between the weldment for placing overlapping, reduces the adsorption capacity between adjacent weldment.

Since a welding process is related to two kinds of weldments, piece uploading component above-mentioned at least needs to prepare 2 sets, this two Set piece uploading component is symmetrically placed in workbench two sides on the basis of the first datum level, specific size and specification setting with weldment Subject to matching, such as the biggish alignment table of area, piece uploading hopper and the bigger piece uploading handgrip of suction, essence can be used in biggish weldment Position handgrip.

For two sets, in continuous production process, the weldment on workbench is removed after completing welding, and distribution is placed on two On alignment table and the weldment that has been pre-positioned is moved on workbench at once and is welded, and two piece uploading handgrips are again respectively from each New weldment is grabbed from the piece uploading hopper of side, is transferred on two alignment tables and is pre-positioned respectively, prepares next round weldering It delivers a child production, so that the utilization rate of laser head greatly improved, improves production efficiency.

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

As a kind of mode of the magnetic device position of saying good-bye of adjustment, multiple grooves, each groove is arranged in the edge of piece uploading hopper Inside it is fixedly installed a guide rail for extending perpendicularly to side corresponding to the groove, magnetism device of saying good-bye is vertically installed at guide rail On, magnetism device of saying good-bye is moved along guide rail, to adapt to various sizes of weldment.

As the mode of the magnetic device position of saying good-bye of another adjustment, multiple holes, magnetic is arranged in the distribution of piece uploading hopper upper surface Property device of saying good-bye be removably mounted in multiple hole, by select different holes so that magnetism is said good-bye device adapt to it is different The weldment of size.

The bottom end of piece uploading handgrip is equipped with several suckers, adjusts the adsorbed state of sucker by cylinder to grab or unclamp Weldment.Since weldment is stacked in piece uploading hopper, in order to which piece uploading handgrip successfully can successively grab weldment, piece uploading handgrip is set Being set to can move on the direction perpendicular to ground；In addition, since piece uploading hopper is usually located at alignment table side, piece uploading Handgrip is also configured to can be mobile in the direction on ground in level, i.e., moves horizontally along piece uploading handgrip walking axle.

Piece uploading handgrip realizes that the horizontal mode mobile in ground direction is as follows:

Piece uploading handgrip walking axle is provided with the first rack gear on side upward, and piece uploading handgrip is fixedly mounted on the first support frame On, it is also fixedly installed with first gear and first motor on the first support frame, we are by being engaged on the first tooth for first gear For mode on item so that piece uploading handgrip is mounted in piece uploading handgrip walking axle, first gear is arranged to the drive in first motor Dynamic the first rack gear of lower edge is mobile, so that piece uploading handgrip can be moved along piece uploading handgrip walking axle.

Piece uploading handgrip is realized as follows perpendicular to the mobile mode in ground direction:

Aforementioned first support frame is by the first connecting plate parallel to the ground and is vertically disposed at the first one end of the connection board Second connecting plate is constituted, and piece uploading handgrip is mounted on the second connecting plate by way of another group of rack and pinion engagement, specifically, It is fixedly installed the second rack gear on the cantilever of piece uploading handgrip, the second rack gear extends perpendicularly to ground, on the second connecting plate It is additionally provided with second gear and the second motor for driving second gear, second gear is engaged on the second rack gear, the Two motor driven second gears rotation, since the first support frame is fixed in piece uploading handgrip walking axle, in relative to force Under effect, the second rack gear carries piece uploading handgrip and moves along the direction perpendicular to ground.

Fine positioning handgrip is similar with piece uploading handgrip along the move mode of piece uploading handgrip walking axle, but fine positioning handgrip is set At may only translate, therefore a set of motor gear is only needed to configure, the gear is made to be engaged on the first rack gear as first gear On, which carries fine positioning handgrip and translates along piece uploading handgrip walking axle under corresponding motor driven.

In view of the compactedness of process, weldment first completes pre-determined bit usually on alignment table, then is moved to complete on workbench At the contraposition with another weldment.In order to complete the pre-determined bit of weldment, we are mutually perpendicular provided with two on alignment table Groove is embedded with direction of travel linear type driving mechanism parallel to the ground, such as cylinder, linear motor in groove, wherein The direction of travel in one linear type driving mechanism movement portion is consistent with the direction of travel of laser head, another linear type driving mechanism The direction of travel in movement portion and the direction of travel of laser head are vertical, and the fixed part of two linear type driving mechanisms is respectively positioned on alignment table Side does not influence weldment and places, one pushing plate of each self-retaining in the movement portion of two linear type driving mechanisms, at the beginning of pushing plate Beginning position is respectively positioned on alignment table side, other two side corresponding with pushing plate is provided with baffle or positioning pin.It pushes Plate moves under the action of respective linear type driving mechanism, also moves the weldment being placed on alignment table, until weldering Part is adjacent to completely with two baffles or positioning 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 Perhaps positioning pin is configured to be freely lifted baffle or fixed when being pre-positioned under the driving of cylinder to the baffle of nearly side Position pin rises, and protrudes from alignment table upper surface, and auxiliary weldment positions, and after the completion of pre-determined bit, baffle or positioning pin are fallen, and are hidden In alignment table, weldment is not influenced and is transplanted on workbench, the lifting of baffle or positioning pin is driven by the cylinder completion.In order to guarantee Pre- contraposition effect, the alignment table of two piece uploading components is not contacted with workbench or two parallel sides are configured to concordant.

It is that weldment is transferred to the splicing of the contraposition before being welded on workbench in next step after weldment aligns in advance completely. Since area of work is smaller, in order to not influence the automatic flow of entire welding process, we alignment table and workbench it Between increase a buffer table, in this way, welding weldment, welding end part be located on workbench, rest part is located at buffer table On, at this point, alignment table is vacated, the weldment of next welding is transferred to alignment table and aligns in advance, prepares next round production.

Weldment, which is transferred to workbench by alignment table, to be completed by fine positioning handgrip, for ease of description, is used for piece uploading first The piece uploading component of weldment is defined as the first piece uploading component, and the piece uploading component for the second weldment of piece uploading is defined as the second piece uploading Component, the first piece uploading component include the first piece uploading handgrip walking axle, the first piece uploading handgrip, the first fine positioning handgrip, the first centering Platform, the second piece uploading component include the second piece uploading handgrip walking axle, the second piece uploading handgrip, the second fine positioning handgrip, the second alignment table. First fine positioning handgrip is configured to move along the first piece uploading handgrip walking axle, and the second fine positioning handgrip is configured to along second Part handgrip walking axle is mobile.First piece uploading handgrip walking axle, the second piece uploading handgrip walking axle are vertically disposed at laser head walking Axis two sides, and the first piece uploading handgrip walking axle is located on the same line with the second piece uploading handgrip walking axle, the straight line and laser Head walking axle square crossing.

Since the first weldment, the second weldment complete pre-determined bit on the first alignment table, the second alignment table respectively, connect Get off and only needs to be moved to two weldments on workbench respectively by two fine positioning handgrips, allow design welds together two A end face is just spliced immediately below laser head travel path, and the laser beam for issuing laser head is radiated on end face, completes weldering It connects.

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

Workbench is divided into the area Liang Geban, it is assumed that left side is the first half area, and right side is the second half area, is closed in the first half area The liftable locating rod of a row is arranged in the side in the second half area, which arranges in alignment, the rectilinear direction and laser Always, the bottom end of locating rod is fixed on the same connecting rod direction of travel of head, and connecting rod is hidden in below workbench, on connecting rod also It is connected with a cylinder, connecting rod is provided under the driving of the cylinder and goes up and down, and makes the positions stem segment being fixed on connecting rod Ground protrudes from worktable upper surface or is down in workbench completely.

In order to be completely fixed the weldment placed on the table, we are also provided with two column electromagnet on the table, electricity The direction of travel of the orientation uniform laser head of magnet is consistent, this two column electromagnet is located at the two sides of aforementioned positioning pin, Positioning pin is closed on, before completion is spliced in weldment contraposition, electromagnet does not work, and after the completion of weldment contraposition splicing, electromagnet, which is powered, to be started, Suction is generated, adsorbs weldment tightly on the table.

Fine positioning handgrip is similar with piece uploading handgrip, and bottom end is equipped with several suckers, and the absorption of sucker is adjusted by cylinder State is to grab or unclamp weldment, and in addition to this fine positioning handgrip is also provided with a liftable fixed briquetting, this is fixed Briquetting equally realizes lifting in such a way that cylinder drives, and for applying a pressure on weldment, weldment is made to be fixed on work On platform, certain lateral thrust can be born and be not subjected to displacement.At least one in two fine positioning handgrips is equipped with the fixation briquetting.

It should be appreciated that fixed briquetting may be used also other than it can realize applied force or revocation power with the mode of lifting Same purpose is realized in a manner of through overturning.

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

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

Second fine positioning handgrip moves to above the second alignment table, grabs the second weldment；

The the second fine positioning handgrip for carrying the second weldment is moved to above workbench, the end face that weld the second weldment will It is adjacent to locating rod；

Fixation briquetting on second fine positioning handgrip is fallen, and applies a pressure on the second weldment, keeps the second weldment solid Determine on the table；

Locating rod on workbench is fallen to workbench；

First fine positioning handgrip moves to above the first alignment table, grabs the first weldment；

The the first fine positioning handgrip for carrying the first weldment is moved to above workbench, the end face that weld the first weldment will It is adjacent to fixed the second weldment on the table；

Electromagnet, which is powered, to be started, and on the table by the first weldment, the absorption of the second weldment, prepares welding.

By above procedure, first using the positioning pin of rise as benchmark, the second weldment is set to move to setting position, by setting Second weldment is fixed on setting position by the fixation briquetting set 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 welded to be fixed on laser head On travel path.

If two fine positioning handgrips are assembled with fixed briquetting, it can be fallen after contraposition, subsidiary magnet is by two Weldment is fixed on the table, waits undesirable elements in order to avoid being subjected to displacement or cannot be adjacent in process of production.

It should be appreciated that the height of workbench, buffer table, alignment table should be identical, mobile for the ease of weldment, we are usually Several universal rolling wheels are arranged in distribution on alignment table, buffer table, and the effect of universal rolling wheel is other than the weight of carrying weldment, more It is important that assisting weldment mobile, the apex height of universal rolling wheel should be consistent, and concordant with worktable upper surface.In view of platform Scuffing in face of weldment influences, we can also be laid with felt on alignment table, buffer table.

Lower part component includes for temporarily placing the lower part platform for the weldment that welding is completed, for collecting the weldering for completing welding The lower part hopper of part is transferred to that the pickup handgrip of lower part platform, be used for will be complete for the weldment of welding being completed from workbench The lower part handgrip of lower part hopper, and the third steel for assisting lower part handgrip mobile are transferred to from lower part platform at the weldment of welding Structure.

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

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

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

Lower part handgrip moves to right above lower part platform, moves on to weldment right above lower part hopper from lower part platform after grabbing weldment；

Lower part handgrip drops to setting height, unclamps weldment, weldment is put into lower part hopper.
