Description

Vertical edge welding device

The present invention relates in vertical direction while driving the vertical edge welding device that welding torch welds the quadrature corner portion of two block plates quadrature, that come down to stand vertically.

For example, when assembling is used for the works of large ship bottom, on the steel plate of level the configuration stand vertically many steel plates, be stringer board, form trellis, inboard at each lattice, make welding torch along rib portion (horizontal rib) that stringer board and horizontal steel plate intersect, and stringer board between rib portion (vertical rib) the profiling welding that intersects at a right angle, even on one side welding torch in the horizontal direction or vertical direction move welding (horizontal rib weld reach found rib weld).No matter be any rib weldering, the operator will hand welding torch Visual Confirmation welding position on one side, on one side mobile welding torch, such manual welding, operator's burden is big, and operating efficiency is low again simultaneously.

Thereby recently,, proposed on chassis, to load welding torch and feeler mechanism, by the edge welding device that carries out the welding of rib voluntarily of chassis for horizontal rib welding.For welding torch to the sealing wire profiling, chassis is installed the profiling roller, and is orientated near vertical steel plate, walks on horizontal steel plate, makes the profiling roller always prop up vertical steel plate (for example Japanese patent laid-open 5-169265 communique).

But, when standing the rib welding, because the direction of travel of chassis will be useful on vertical guide stem or vertical guide rail that chassis is moved in vertical direction on vertical direction z.The moving direction of chassis is by this guide rail restriction, thereby, if use above-mentioned feeler mechanism, then its form is ground in parallel (and in vertical direction) fixed guide in two block plates quadrature, that stand vertically in fact one, on chassis, install parallel and can be, and support the welding torch of stretching profiling roller that props up this another steel plate and the quadrature rib that welds two steel plates with respect to the profiling platform of another steel plate advance and retreat with this steel plate.

In this case, the profiling roller only carries out profiling to the surface (leaving the position of quadrature rib in the horizontal direction in a way) of described another steel plate, thereby owing to reasons such as steel plate deflection, bending, inclinations, with the surperficial parallel direction (the advance and retreat direction of profiling roller) of a described block plate on, there have probably between this profiling position and the quadrature rib to be biased poor.In case this position deviation is arranged, the quadrature rib is promptly departed from the welding target location of welding torch, and the size that departs from equals this deviation.

The 1st purpose of the present invention is to alleviate upright rib welding operator's work, increases work efficiency; The 2nd purpose is to improve the copying accuracy of the welding torch that the quadrature rib to two blocks of vertical steel plates of quadrature welds; The 3rd purpose is to provide that frame for movement is simple, reliable in action and the reliable vertical edge welding device of durability; The 4th purpose is to provide and relatively is easy to move into the welding job scene, is easy to be contained in also be easy to from it face on the steel plate that will weld and take off, and is easy to move away from the vertical edge welding device of working site.

Vertical edge welding device of the present invention possesses guide rail component; Be used for this guide rail component is parallel in fact, stand vertically in fact, two block plates (W1, W2) crossing, the vertical in fact lines (Lw) of quadrature and fixing guide rail fixer; At upwardly extending the 1st arm in side (y1) that becomes to be essentially miter angle with respect to described two block plates; Support the 1st arm (y1) to make this arm go up move and go up fixing at its bearing of trend (x) in horizontal direction (y) vertical and vertical direction (z) with this direction (x), and be contained on the guide rail component (51), along guide rail component (51) on its bearing of trend voluntarily, and comprise the chassis (1) that walking drives the motor of usefulness; Apply driving force, on the direction and the approaching again direction of described two block plates (W1, W2) that the 1st arm extends, drive the spring member (k1) of the 1st arm (y1) with respect to chassis; Support with the first arm (y1), substantially be on the 1st arm (y1) direction of extending with crossing rib profiling roller (y7) and the rib welding torch (T) in fact in opposite directions of described two block plates (W1, W2); Supply with the source of welding current of this welding torch (T) electric power; Carry the welding rod feedway of welding rod for this welding torch (T); Be used for switching on the driving chassis, and supply with the controller (C) of welding torch (T) weld power by the described source of welding current to described motor (M).

In order to should be readily appreciated that, it is for referencial use to be marked with shown in the accompanying drawing among the following embodiment mark of corresponding part in bracket.

Adopt such structure, by the 1st arm (y1), profiling roller (y7) and rib welding torch (T) are under the support of chassis (1), can become the direction (x) of miter angle upward free to advance or retreat at vertical steel plate (W1, W2) in fact, and drive toward direction near two block plates (W1, W2) with spring member (k1) with respect to two quadratures.Make relative two steel plates of guide rail component (51) (W1, W2) keep the distance of regulation, so that profiling roller (y7) is facing to the crossing rib of two steel plates (W1, W2), the concavo-convex or crooked of direction to the bisecting line at the angle that become along two steel plates (W1, W2) moves do profiling, it is the same mobile that welding torch and this profiling are moved, thereby welding torch can be done correct profiling with respect to rib.

The 1st enforcement state of the present invention possesses, support profiling roller (y7) and welding torch (T), and be linked to the 2nd arm (y3, y6) of described the 1st arm (y1), the 2nd arm can be that the center rotates to go up the axle (y2) that extends in the vertical direction (z) with extending direction (x) quadrature of the 1st arm (y1).

Adopt this structure, profiling roller (y7) can move on (y) direction that reaches perpendicular to described direction (x) (z) in vibration, thereby, if profiling roller (y7) breaks away from rib deflection y direction, only touches a block plate (W1), under this state, adding spring member (k1) on the profiling roller (y7) along the direction applied pressure that becomes miter angle with this steel plate (W1), thereby, will slide along the surface of steel plate (W1), shift to direction near another steel plate (W2).In order to realize that this moves, profiling roller (y7) must vibrate on the y direction.The 2nd arm (y3, y6) makes this vibration become possibility.Profiling roller (y7) slides on steel plate (W1) surface owing to this vibration, in case meet another steel plate (W2), this steel plate (W2) promptly stops profiling roller (y7) moving on the y direction.Thereby profiling roller (y7) automatically is positioned to run into simultaneously the position of two steel plates (W1, W2), promptly on the rib of two steel plates.

In a word, under the 1st enforcement state, profiling roller (y7) not only to the upright rib of two steel plates (W1, W2) along two steel plates (W1, W2) become the concavo-convex or crooked of 2 bisector directions at angle to move do profiling, and the concavo-convex or crooked of y direction moved do profiling, thereby it is higher to the precision of rib profiling, however, the structure of for this reason taking is extremely simple.

The 2nd example of the present invention, be on the structure of the 1st example, increase and support described welding torch (T), and be linked to the 3rd arm (y4) of described the 2nd arm (y3, y6), the 3rd arm (y4) can be the center rotation to go up the axle (y2) that extends in the vertical direction (z) with the 1st arm (y1) extending direction (x) quadrature; Also increase and adjust the 3rd arm (y4) with respect to the 2nd arm (y3, the device of anglec of rotation y6) (y11a-y15).

Adopt this structure, can be on the y direction (W1, W2) the welding datum line (Lw) of upright rib move, adjust the welding target location of welding torch (T) with respect to two steel plates.At 1 welding bead just under the situation of weld, can be welding the target location as welding datum line (Lw).Be expansion weld seam waist height (width of weld seam y direction), need carry out many welding bead welding.For example, under the situation of 3 welding beads, to serve as welding datum line (Lw) with the welding target location of the 1st welding bead, the welding target location of for example the 2nd welding bead is decided to be the position that is solded into a side steel plate (W1) by welding datum line (Lw), the welding target location of the 3rd welding bead is decided to be the position that is solded into opposite side steel plate (W2) by welding datum line (Lw).These welding target locations can use adjusting device (y11a-y15) to set.The same with above-mentioned the 1st embodiment, the rib copying accuracy height of profiling roller (y7), and the adjustment of the welding target location of being undertaken by adjusting device (y11a-y15) is the welding target location adjustment that profiling roller (y7) carries out with respect to profiling position (welding datum line Lw), so the welding of each welding bead reaches very high copying accuracy with respect to rib, all uniform many welding bead welding of weld width and throat depth have been realized.

Implement among the common embodiment of state in the present invention the 1st to 3, guide rail component (51) is dull and stereotyped; Guide rail fixer (60a, 60b) becomes come down to rail brackets (60a, 60b) that 45 positions spent support this guide rail component (51) with the guide rail component platen surface with respect to described two block plates (W1, W2) for being fixed in one of described two block plates (W1, W2) (W2).

Adopt this structure, chassis (1) is ridden on the platen surface of guide rail (51), the 1st arm (y1) is installed on the chassis (1), and it can be moved in the x direction with guide rail component (51) quadrature, at this 1st arm (y1) is extended automatically on the direction that becomes to come down to miter angle with respect to two steel plates (W1, W2).This combination of guide rail component (51), chassis (1) and the 1st arm (y1) is the simplest structure of structure (around the chassis) that makes the 1st arm (y1) and combine with chassis (1).Therefore, the supporting structure of guide rail component (51), promptly become the structure of the rail brackets (60a, 60b) of miter angle guide rail support member (51) will become complicated with respect to steel plate (W1), but this supporting structure needn't spread all over the total length of guide rail component (51) all to be implemented, and leave rib, be in position again, thereby cause the imitative possibility that hinders less to welding operation near a side steel plate (W1).

Above-mentioned chassis surrounding structure simply makes the volume of chassis surrounding structure reduce (miniaturization), make the welding chassis installation, take out of and become easy.Be subjected to the trouble that barrier stops when also having reduced trolley running.

In the 4th enforcement state of the present invention, it can be the backstay (56b) of center rotation with the vertical in fact axle (55b) of platen surface of the steel plate (W2) fix with respect to the support of this guide rail that rail brackets (60a, 60b) comprises.

Referring to Fig. 3, because another steel plate (W1) and this steel plate (W2) quadrature, thereby this axle (55b) is parallel with another steel plate (W1).Rotational positioning bar (56b) is to making its free end (front end) become the angle of beeline with respect to the surface of this steel plate (W1).Rail brackets (60a, 60b) is moved to till this free end touches the surface of steel plate (W1) with respect to steel plate (W2), be fixed in then on the steel plate (W2), make rail brackets (60a, 60b) become the specific length that length was determined of backstay (56b) with respect to the distance of steel plate (W1) with this.

Height (distances of 51 couples of W2) by means of length that is predetermined backstay (56b) and rail brackets (60a, 60b), make the extensions of major axis of the 1st arm (y1) and welding benchmark base (Lw) quadrature of rib, utilize above-mentioned rail brackets (60a, 60b) with respect to the location of steel plate (W1) and fixing on steel plate (W2) again, profiling roller (y7) is located the welding datum line (Lw) of rib automatically.Therefore, be used for making profiling roller (y7) just simple to guide rail (51) location of rib profiling.

In one embodiment of this invention, guide rail component (51) comprises the parallel rack (50) that is parallel to its longitudinal axis bearing of trend; Chassis (1) then comprises the decelerator that is driven by described walking drive motor (M) and is contained on the output shaft of this decelerator, and with the pinion of described tooth bar engagement.

Fig. 1 represents the outward appearance of one embodiment of the invention.Vertical steel plate W1 (calling left vertical panel W1 in the following text) vertically is fixed in vertical steel plate W2 (calling right vertical panel W2 in the following text) surface with the location welding, and tabular guide rail 51 is vertically placed, and becomes miter angle to be fixed in right vertical panel W2 with respect to right vertical panel W2 surface.On this guide rail 51, chassis 1 is installed.Chassis 1 is shown in Fig. 2 in the being seen front of Fig. 1 arrow 2A direction, and the welding torch supporting mechanism of chassis 1 bottom is shown in Fig. 3 at the being seen lower surface of Fig. 1 arrow 3A direction, and chassis 1 is shown in Fig. 4 at the being seen right flank of Fig. 1 arrow 4A direction.

The angle (rib) that left side vertical panel W1 and right vertical panel W2 intersect is exactly the position that will weld, is positioned on this angle of left vertical panel W1, and is welding datum line Lw in the sideline that vertical direction is extended.The direction of extending with this welding datum line Lw is a vertical direction z direction below, right vertical panel W2 being become 45 degree with left vertical panel W1, and with the horizontal direction of this welding datum line quadrature be the x direction, with vertically and the horizontal direction of x and z direction be the y direction.

A. the structure of guide rail 51 and guide rail support 51

Rail brackets 60a and 60b (see figure 4) that guide rail 51 usefulness are fixed thereon end and bottom are fixed on the right vertical panel W2.From Fig. 3 as seen, rail brackets 60a erects supporting arm 52b on the surface of aluminium sheet 57b, is fixing magnet 58a, 58b at the back side of this aluminium sheet, and magnet 58a, 58b inhale on right vertical panel W2, so that aluminium sheet 57b and right vertical panel combine abreast.Front end-plate supporting arm 52b, that guide rail 51 is fixed becomes 45 degree to tilt with respect to the pedestal of supporting arm 52b, makes 51 couples of right vertical panel W2 of guide rail become miter angle with this.

Fixing support plate 53b on the aluminium sheet 57b, on this support plate 53b vertically (with left vertical panel W1 abreast) supporting on this mandrel rod 55b, backstay 56b to be installed by mandrel rod 55b, and this backstay is rotatable freely.Backstay 56b is owing to the effect of disk spring is subjected to the friction catch of support plate 53b, thereby during to the bigger revolving force of backstay 56b, backstay 56b is the center rotation with mandrel rod 55b just the operator, and do not rotate when not adding revolving force.

The structure of the rail brackets 60b also structure with 60a is identical.When guide rail 51 was fixed in right vertical panel W2, the operator was horizontal rail brackets 60a and 60b backstay (56b) separately respectively, and the front end of two backstays props up left vertical panel W1 together, and guide rail 51 is located with respect to left vertical panel W1.With this, make guide rail 51 with respect to left vertical panel W1 keeping parallelism, and it is kept predetermined distance.Magnet 58a, the 58b of rail brackets 60a and 60b, 58c, 58d inhale on right vertical panel W2, so that guide rail 51 is parallel to right vertical panel W2, and to its maintenance predetermined distance.

And in case chassis 1 moves up, following arm y6 meets the backstay 56b of rail brackets 60a, and backstay 56b leaves the mobile route of arm y6 promptly because of the effect of the arm y6 rotation that makes progress.In case chassis 1 moves down, following welding torch T runs into the backstay of rail brackets 60b, and then backstay leaves the mobile route of welding torch T because of the effect of welding torch rotates.

And, under the long situation of guide rail 51, between above-mentioned upper and lower rail brackets 60a, 60b, also fix more than one rail brackets again with spline structure.

The tooth bar 50 of extension in parallel is installed on guide rail 51.The side end face of guide rail 51 becomes the herringbone (see figure 3), so that the position of wheel on the y direction of regulation chassis 1.Be used for regulation chassis 1 on move the switch ram SRT of boundary and stipulate that its switch ram SRB that moves down boundary tightens with not shown countersink head screw (being positioned at the inboard of guide rail 51 at Fig. 1) and be fixed in guide rail 51, can unclamp each countersink head screw respectively, tighten countersink head screw again after moving up and down the position, adjust the upper and lower position with this.Moreover when switch ram SRT ran into the contact of upper limit position switch ST of chassis 1 upper end, switch S T switched to closure from disconnection, and the reverse rotation drive circuit of the lifting drive motor M of chassis 1 disconnects, and chassis 1 stops to move up.And when running into the contact of lower position switch SB of chassis 1 inside in the upper end of switch ram SRB, switch S B switches to closure from disconnection, and the drive circuit that is rotated in the forward of the lifting drive motor M of chassis 1 disconnects, and chassis 1 stops to move down.

B. chassis 1

Chassis 1 is incorporated into guide rail 51, rises or descends along guide rail 51.In chassis inside the lifting drive motor is arranged, be engaged on the tooth bar 50 of guide rail 51 by being incorporated into the pinion 40 that reducing gear on the output shaft (not shown go out) is driven in rotation.On chassis 1, there is width (x direction) to clip a pair of of guide rail 51 at profiling roller 41a, the 41b of z direction downside and same a pair of profiling roller at z direction upside at guide rail 51, each can rotate under the support of the 42a of supporting mechanism respectively freely to (41a) in the profiling roller, and another roller can rotate under the support of the 42b of supporting mechanism respectively freely.

42a of supporting mechanism and 42b, respectively be that right-handed thread and the right-handed thread that the boundary has screw rod 1b right-handed thread and left hand thread, on the x direction respectively combines with the mid point.End at screw rod 1b is equipped with loading and unloading knob 1a, make knob 1a hand of spiral rotation to the right, then clip guide rail 51 profiling roller (41a) in opposite directions and the distance shortening between the profiling roller (41b), each 1 pair of profiling roller clips guide rail 51 (see figure 3)s up and down, and chassis 1 is located on the y direction with respect to guide rail 51.That is the profiling roller is connected on the guide rail 51, and moves freely along the z direction and to carry out profiling, and 50 one-tenth engagements of above-mentioned pinion 40 and tooth bar.In case lifting drive motor M is subjected to drive rotation under this state, pinion promptly is subjected to rotation and drives, and chassis 1 is promptly driven up or down.

Otherwise, then elongated if knob 1a is rotated to the direction opposite with dextrorotation in x direction profiling roller (41a) and the distance between the profiling roller (41b) in opposite directions, chassis 1 can be taken off from guide rail 51 on the y direction.On chassis 1 top described upper limit position switch ST is arranged, described lower position switch SB is arranged in chassis 1 bottom.

C.x direction driving and reversing mechanism 10x

Can see from Fig. 1, Fig. 2, Fig. 3, x direction driving and reversing mechanism 10x is installed in chassis 1 bottom.Support plate x5a is being fixed in the lower end of chassis 1, on this support plate x5a, fixing upwardly extending guide rail x5b (see figure 4) in x side, slide block x7 is connected on this guide rail x5b, and removable on the direction of its extension, and this slide block x7 and guide rail x5b combine on y and z direction.Be that slide block x7 can not move with respect to guide rail x5b on y and z direction, x7 is being supported by guide rail x5 at these direction top shoes.On slide block x7, fixing the cushion block x6 that is used for supporting y direction guiding mechanism 20y.

From Fig. 2 as seen, the front that connects the slide bar x2a of compression helical spring k1 connects cushion block x6, is fixing being used for preventing the nut x2b that cushion block x6 deviates from the pin thread of this front of slide bar x2a.Slide bar x2a can rotate with respect to cushion block x6.Slide bar x2a connects bullport that is fixed on the angle bar x4 on the support plate x5a and the sleeve x3 that is fixed on this angle bar x4.Fixing knob x1 in end slide bar x2a, that protrude in sleeve x3 outside (on the right of Fig. 2).

At Fig. 2, slide bar x2a is pulled out to the right one, cushion block 6 is compressed, is moved to right-hand on one side compression helical spring k1 on one side.Pulling force and constraint one to slide bar 2a are removed, and are moved to the left at the elastic force effect lower cushion block x6 of compression helical spring k1, and at this moment slide bar x2a is promoted by cushion block 6 and moves to left.

Guiding slide bar x2a carries out on the sleeve x3 of above-mentioned move left and right, its end separately has sleeve pair of notches x3a (table side and each 1 of inboard, two) in two totally, the pin x2c (table side and each one of inboard, totally two) that is inserted on the slide bar x2a enters this otch x3a.At the front end face of sleeve x3, on the position that becomes cross with respect to 1 couple of otch x3a, form pin standing groove x3b.As shown in Figure 2, enter at pin x2c under the state of otch x3a (under the profiling set condition), the bounce of compression helical spring k1 is added on the cushion block x6, cushion block x6 is crushed on left, in case it is right-hand that cushion block x6 is pressed towards, compression helical spring k1 is compressed, and cushion block x6 moves right.The power one of cushion block 6 to right-hand pressure is weakened, and spring k1 is about to cushion block x6 and pushes back left.

The operator draws knob x1 to right-hand, pin x2c is moved to right-hand from the right side of sleeve x3, knob x1 is revolved to turn 90 degrees again, unclamps the pulling force to knob x1, and pin x2c promptly embeds pin standing groove x3b, holds slide bar x2a it can not be moved to the left.That is cushion block x6 keeps moving to right (keeping out of the way) position, and compression helical spring k1 keeps compression, and sliding excellent x2a stops to be moved to the left (be in and keep out of the way set condition).Under this state, knob is driven a little to the right, thereby pin x2c is pulled out from pin standing groove x3b, then knob x1 is revolved and turn 90 degrees, releasing is to the pulling force to the right of knob x1, the bounce of compression helical spring k1 is about to cushion block 6 and drives to left, and pin x2c enters in the otch x3a, reaches profiling set condition shown in Figure 2.

Moreover, as previously mentioned, make rail brackets 60a and 60b backstay 56b maintenance level separately, make the front end of two backstays prop up left vertical panel W1 together, thereby after guide rail 51 located with respect to left vertical panel W1, be fixed in right vertical panel W2, and, as previously mentioned, each clamps guide rail 51 (Fig. 3) with a pair of profiling roller (41a, 41b) top of chassis 1 and below, makes 50 one-tenth gears engaged of pinion 40 and tooth bar.Under such state, if get above-mentioned profiling set condition, then before cushion block x6 arrived the extreme position that moves to left shown in Figure 2, profiling roller y7 propped up left vertical panel W1 and right vertical panel W2, stops cushion block x6 to be moved to the left with this.Under this state, chassis 1 moves up or down, since left vertical panel W1 or the bending of right vertical panel W2, left vertical panel W1, the concavo-convex or bending etc. with respect to the end face of right vertical panel W2, cause that two vertical panel W1, the W2 angle of cut have under the situation about departing from respect to the straight line parallel with the z axle in the distribution position, the z direction of the x direction that the 2nd arm y3 extends, owing on profiling roller y7, be added with the bounce of compression helical spring k1, on this position of departing from, profiling roller y7 moves on the x direction.That is, profiling roller y7 along with the angle of cut of two vertical panel W1, W2 on the x direction position deviation and on the x direction profiling move.

D.y direction guiding mechanism 20y

(6) setting of the welding target location of welding torch T (y direction)

(with how many roads finish by welding corresponding to predetermined welding bead number for the operator?), set the welding target location (datum line Lw is the y direction position of benchmark with welding) of the 1st welding bead with described y direction guiding mechanism 20y.For example,, or finish with 3 welding beads under the situation of welding, will weld the target location and be used as welding datum line Lw only with the 1st welding bead.

(7) welding

The welding firing switch PB1 (closure) of expression " RUN " on operator's push panel.And, this firing switch PB1 and the welding shutdown switch PB2 of expression welding " stopping " are snap switch (closures when only pinning, pressure is removed the switch that promptly recovers off state), but switch P B1 is the normally closed switch of closure when pinning, and switch P B2 is the normally closed switch that disconnects when pinning.Controller C carries out following " C. welding " along with switch P B1 closure, as long as welding shutdown switch PB2 does not disconnect, just indicates source of welding current PS energising welding, and driving chassis 1 descends, lower position switch SB-closure, and at this place, chassis 1 promptly stops, and stops welding.Then, drive chassis 1 and rise, upper limit position switch ST-closure is promptly stopped at this place's chassis 1.That is Yi Bian chassis 1 is descended, Yi Bian carry out the welding of 1 welding bead, this welding one finishes, and promptly automatically drives chassis 1 and is back to upper limit position.

When the operator carries out the welding of the 2nd welding bead at needs, the same with above-mentioned (6), set the welding target location of the 2nd welding bead with aforementioned y direction guiding mechanism 20y.Then, make firing switch PB1 closure once again.Controller responds to this, carries out " c. welding " pattern.The 3rd welding bead and later welding operation are too.

(8) guide rail removes

Operator's pull-turn button x1 makes pin x2c move to the more outside place, right side of sleeve x3, with knob 90 degree, removes the pulling force to knob x1 again, and pin x2c promptly embeds pin standing groove x3b, stops slide bar x2a to be moved to the left.That is, the original state (keeping out of the way) after cushion block x6 keeps being moved to the left, compression helical spring k1 keeps compressive state, and slide bar x2a stopped to (the keeping out of the way set condition) that moving to left.Then, will load and unload knob 1a to counter rotation, profiling roller (41a, 41b) is launched, getaway takes off chassis 1 from guide rail 51, then guide rail 51 is unloaded from right vertical panel.

A. chassis drives downwards

Power switch SW1 one connects, and the indicator lamp of controller C is promptly lighted, and power supply is promptly supplied with 100 volts alternating current to the entire circuit of controller C.Between the input of the output of power switch SW1 and late-class circuit, insert fuse NFB, any abnormal conditions takes place at circuit, when having overload current to take place, can shield to late-class circuit.

The operator pulls change-over switch SW2 from middle position to " decline " side, then in controller C (see figure 6), contact engage relay coil 22 1 sides of switch SW 2,100 volts alternating voltage in addition on the series circuit of relay contact x5c and relay coil 22, relay contact x3a, x3b closure, the motor power-on circuit of speed control circuit plate NTW1 make size corresponding to the electric current of the setting voltage of potentiometer VR1 from forward by chassis drive motor M, motor M forward rotation, the pinion that is engaged in tooth bar 50 just changes, and chassis 1 descends.

In a single day change-over switch SW2 gets back to the centre position, and the alternating voltage that leads to the series circuit of relay contact x5c and relay coil 22 is cut off, thereby contact x3a, the x3b of relay 22 disconnection, stops the energising to motor M, and chassis 1 stops.Even do not get back at change-over switch SW2 under the situation in centre position, in case also be lower position switch SB closure (chassis 1 arrives upper limit position), relay coil 25 is promptly switched on, normally closed relay contact x5c disconnects, relay coil 22 stops energising, contact x3a, x3b disconnect, and motor M stops energising, and chassis 1 stops.

B. chassis upwards drives

The operator with change-over switch SW2 from middle location plate to " rising " side, in controller C (see figure 6), the contact of switch SW 2 is connected to relay coil 24, on the series circuit of relay contact x6b and relay coil 24, add 100 volts alternating voltage, relay contact x4a, x4b closure, the motor power-on circuit of speed control circuit plate NTW1 makes size and the corresponding current reversal of the setting voltage of potentiometer VR1 flow into chassis drive motor M, motor M reverses, be engaged in the pinion backward rotation of tooth bar 50, chassis 1 rises.

Change-over switch SW2 one gets back to the centre position, and the alternating voltage that series circuit led to of relay contact x6b and relay coil 24 promptly is cut off, thereby contact x4a, the x4b of relay 24 disconnection, and motor M institute galvanization stops, and chassis 1 stops.Even do not return at change-over switch SW2 under the situation in centre position, also be upper limit position switch ST closure (chassis 1 arrives the lower position), relay coil 26 is promptly switched on, normally closed relay contact x6b disconnects, the energising of relay coil 24 stops, relay contact x4a, x4b disconnect, and motor M stops energising, and chassis 1 stops.

And above-mentionedly utilize the decline that change-over switch SW2 carries out/rising to drive, only do not enter under the situation of control model of " the c. welding " that the following describes just effective at controller C.This situation just weld before the beginning or stop button PB2 by by (disconnection), relay coil is a non-power status, normally closed contact x1c closure, all relay tips were got back to originally the state of (before the welding beginning), became the holding state of " c. welding " pattern.When carrying out the control model of " c. welding ", relay coil 14 energisings, this normally closed contact x1c disconnects, thereby change-over switch SW2 closure is in " decline " or " rising " side, can be owing to the effect of change-over switch SW2 to relay coil 22 or 24 energisings, above-mentioned " a. chassis drive downwards " or " b. chassis upwards drives " action can not occur.But, owing to carry out the control model of " c. welding ", so while be to weld chassis 1 to descend, or chassis rises after having welded 1 welding bead.The operation of change-over switch SW2, to the action of this " c. welding " pattern without any influence.The action of this " c. welding " pattern is stopped, must be by welding shutdown switch PB2 (making its disconnection).

C. welding

Operator one closes and welds firing switch PB1, and relay coil 13 is promptly switched on, and its normal off relay contact x1a, x1b are promptly closed, and normally closed relay contact x1c promptly disconnects.The disconnection of normally closed relay contact x1c makes chassis not respond the driving of change-over switch SW2.Since the closure of normal off relay contact x1a, relay coil 14 self-insurances (even switch P B1 recovers off-state, relay coil 14 also continues energising).Since the closure of relay contact x1b, thus relay coil 18 energisings, relay contact (normal off) x2a and x2b closure.The closure of relay contact x2a causes again to relay coil 22 energisings (above-mentioned chassis 1 drives downwards), and the closure of relay contact x2b is then connected the welding start triggering circuit of source of welding current PS, thereby begins the welding with welding torch T.Moreover the welding rod that welding rod feedway (not shown) the response source of welding current PS that send welding rod for welding torch T sends is supplied with control signal, and welding rod is sent into welding torch T.The state that Here it is when welding, chassis 1 descends on one side, welds on one side welding torch T stretches out welding rod.

In this state, one by welding shutdown switch PB2 (disconnections), and the energising of relay coil 14 promptly stops, and relay contact x1a and x1b disconnect, and relay coil 18 and 22 energising stop, thereby welding here stops and chassis 1 stops decline.Because it is closed that normally closed reed x1 recovers, thereby after stopping welding like this, become possibility by means of change-over switch SW2 to relay coil 22 or 24 energisings, according to the operation of change-over switch SW, the call by pattern of above-mentioned " a. chassis drives downwards " or " the b. chassis upwards drives " is to carry out.

In case welding shutdown switch PB2 does not disconnect, lower position switch SB switches to closure (chassis arrival lower position) from disconnection, relay coil 25 is promptly owing to the closure of lower position switch SB is switched on, and normally closed relay contact x5a and x5c disconnect, and normal off contact x5b closure.The electric current of relay coil 18 has been switched in the disconnection of relay contact x5a, thereby relay contact x2b disconnects, and source of welding current PS stops to supply with weld power to welding torch T.The electric current of relay coil 22 has been cut off in the disconnection of relay contact x5c again, thereby chassis 1 stops to descend.Because normal off contact x5b closure, timer 19 is switched on, is picked up counting.The timing of timer 19 1 end setup time T 1 (regularly arriving), timer 19 just makes its contact T1a, T1c closure, and T1b, T1d, T1e disconnect.Make timer 19 self-insurances with this, relay coil 24 energisings, chassis 1 rises.Because the rising of chassis 1, lower position switch SB recovers off-state from closure, so the energising of relay coil 25 promptly stops ending, contact x5a gets back to closure state, contact x5b gets back to off-state, and contact x5c recovery is closed, and because timer contact T1b disconnection, the T1c closure, chassis 1 continues to rise.Chassis 1 arrives upper limit position, and upper limit position switch ST switches to closure from disconnection, and relay coil 26 is promptly switched on, and contact x6a, x6b disconnect.Because the disconnection of x6b, chassis 1 stops, because the energising of the disconnection of x6a (because at this moment T1d disconnects) relay coil 14 stops, x1a, x1b disconnect, and the self-insurance of relay coil 14 is disengaged, and the energising of relay coil 18 and timer 19 is cut off.

Moreover, welding shutdown switch PB2 one disconnection when this chassis 1 is rising, the energising of relay coil 14 promptly stops, relay contact x1a, x1b disconnect, chassis 1 stops, by means of change-over switch SW2 relay coil 22 or 24 energisings are become possibility, according to the operation of change-over switch SW, above-mentioned " a. chassis drives downwards " or " the b. chassis upwards drives " carried out.

The feature of the foregoing description is summarized as follows.

(1) fixed guide support 60a, 60b make guide rail 51 become 45 degree with respect to the surface of right vertical panel W2, and each backstay (56b) of these supports is horizontal, the front end of each bar contacts the surface of left vertical panel W1 again, again guide rail 51 is fixed in right vertical panel W2, make guide rail 51 become predetermined distance and keeping parallelism with this, and the platen surface of guide rail 51 become 45 degree with respect to left and right vertical plate W1, W2 with respect to left and right vertical plate W1, W2.

In case chassis 1 being loaded onto the extended line of the longitudinal axis of guide rail 51, the 1 arm y1 substantially intersects with welding datum line Lw automatically.That is the longitudinal axis of the 1st arm y1 becomes 45 degree to left and right vertical plate W1, W2, and with welding datum line Lw quadrature in fact.Profiling roller y7 is supported by the 2nd arm y3 by profiling roller y6, the 2nd arm y3 and the 1st arm y1 almost parallel, thereby profiling roller y7 is automatically in fact facing to welding datum line Lw.

Compression helical spring k1 is pressed in the 1st arm y1 on the direction near welding datum line Lw, thereby profiling roller y7 enters the inside that the angle of welding datum line Lw with left and right sides vertical panel W1, W2 position contacting, is promptly arranged simultaneously.That is the left and right sides vertical panel W1, the W2 that are pressed in this angle automatically are above both.

(2) if owing to the reasons such as bending of left and right sides vertical panel W1, W2, the 1st arm y1 can not reach with respect to left and right sides vertical panel W1, W2 and become 45 degree respectively, even in this case, also because the 2nd arm y3 can be by the mandrel rod y2 that extends in the z direction, with respect to the 1st arm y1 rotation, again because as mentioned above, helical spring k1 extruding by compression, so the 2nd arm y3 rotates, make profiling roller y7 enter while and left and right sides vertical panel W1, W2 position contacting, promptly have the inside, angle of welding datum line Lw.

Roller y7 can be with respect to the correct profiling of angle (welding datum line Lw) of left and right sides vertical panel W1, W2 when mobile on the z direction to make chassis 1 with this.

Because welding torch T is supported by the 2nd arm y3 by the 3rd arm y4, thereby the track identical in fact with the profiling motion track of profiling roller y7 (but move parallel with the motion track of roller y7) retouched out in the welding target location of welding torch T.Thereby the welding position of welding torch T in chassis 1 moves along the z direction is accurately with respect to welding datum line Lw.Even left and right sides vertical panel W1, W2 have problem such as bending and cause welding datum line Lw bending, also can obtain exactly along the weld seam of welding datum line Lw and stable isosceles height (width is the same), welding quality is improved.

(3) the adjustment knob y14 of operation y direction guiding mechanism 20y can adjust the track with profiling motion track (welding datum line Lw) the welding target location relative, welding torch T of profiling roller y7 on the y direction.For example, when having welded 1 welding bead, make identical the getting final product of profiling motion track (welding datum line Lw) of track and profiling roller y7 of the welding target location of welding torch T, but during the welding more than finishing 2 welding beads, the welding target location (y direction) of welding torch T in each welding bead is adjusted in the welding target location of the welding torch T that can be predetermined at each welding bead (datum line Lw is the position of the y direction of benchmark with welding).Thereby, under the situation of many welding bead welding, even welding benchmark Lw bending also can obtain exactly along welding datum line Lw and stable isosceles height (width is the same) weld seam, the raising welding quality.

(4) support the 1st arm y1 movably on chassis 1 in the x direction, support profiling roller y7 and welding torch T with the 1st arm y1, with compression helical spring k1, slide bar x2a and knob x1 the first arm y1 is set in profiling position and retreating position, thereby the setting of the profiling position of profiling roller y7 and welding torch T and retreating position is easy.

When being set in the profiling position, compression helical spring k1 pressurizes to the profiling of profiling roller, be that compression helical spring k1 is used for driving the 1st arm and profiling pressurization to the profiling position simultaneously, thereby profiling position/retreating position is set, and the combination of the mechanism of usefulness and feeler mechanism is simple, simple in structure, reliability is high.

(5) rotate loading and unloading knob 1a, can take off heavier chassis 1 from long guide rail 51, or chassis 1 is loaded onto guide rail 51, that is, can more simply chassis 1 be loaded on guide rail 51.Thereby, for example can finish in a certain place welding one, promptly unload chassis 1, move guide rail to next welding place, be set in behind this place chassis 1 (and welding rod feedway) shipped and be contained on the guide rail 51, be easy to carry guide rail 51 and be arranged at and weld the place.

(6) put chassis 1 in upper limit position, the operator makes firing switch PB1 closure, controller C promptly begins welding automatically, drive chassis 1 is descended, be welded to the lower position, promptly stop welding automatically, and it is downward to stop to drive chassis 1, automatically upwards drive chassis 1 then, behind upper limit position, the chassis 1 that stops is waited for operator's indication (switching manipulation), thereby the operator needn't often and then look after the device of the foregoing description, possible many of the device of the foregoing description uses simultaneously, can improve operator's operating efficiency.

(7) possesses the manual operation change-over switch SW2 that is independent of welding firing switch PB1 and welding shutdown switch PB2.The operator pulls this switching switch SW 2 to the decline side, controller C promptly drives chassis 1 and descends, and because chassis 1 arrives, lower position switch SB switches to closure from disconnection, or change-over switch SW2 gets back to stop position (centre position) before, drives chassis 1 and descends always.Equally, operator one pulls change-over switch SW2 to uplifted side, controller C promptly drives chassis 1 and rises, in the arrival owing to chassis 1, upper limit position switch ST switches to closure from disconnection, or change-over switch SW2 gets back to before the centre position, drive chassis 1 rises always, and welding torch T no power at this moment, thereby, confirm the running of walking about of chassis 1 that z direction welding final position and welding starting position are used easily in advance.

(8) on the basis of (7), be used for upper limit position switch ST and lower position switch SB from disconnection switch to the closed ram SRT of switch up and down and SRB also can be freely in the z direction with respect to guide rail 51 adjusting positions.Promptly in above-mentioned (7), will descend switch ram SRB to be fixed on lower position switch SB closure, chassis 1 is stopped on the position of welding final position; To go up switch ram SRT and be fixed on upper limit position switch ST closure, chassis 1 is stopped on the position of welding starting position.Thereby the welding starting position of z direction and welding final position are all decided.This can carry out according to Visual Confirmation reality welding torch T welding target location, for the operator, is easy to, reality.
