Description

Vertical edge welding device

The present invention relates to drive in vertical direction on one side welding torch and vibrate the vertical edge welding device that the quadrature rib portion of quadrature and two block plates that in fact stand vertically is welded on one side in the horizontal direction.

For example, the occasion that is used for the bottom structure thing of large ship in assembling, the many steel plates that to vertically erect on the steel plate of level (being stringer board) are configured to trellis, and in each lattice inboard, making welding torch carry out profiling along the rib portion (vertical rib) that intersects at a right angle between rib portion (horizontal rib) that stringer board and horizontal steel plate intersect and the stringer board welds, that is to say make welding torch on one side in the horizontal direction or vertical direction move, weld (horizontal rib welding and vertical rib weld) on one side.No matter be any, the operator will hand welding torch, Visual Confirmation welding position on one side, on one side the manual welding of mobile welding torch, operator's burden is big, the while inefficiency.

Therefore recently,, proposed on chassis, to carry welding torch and feeler mechanism, utilized chassis voluntarily, carried out the edge welding device of the welding of rib for horizontal rib welding.In order to make welding torch to the sealing wire profiling, the profiling roller is installed on chassis, allow the profiling roller always contact with vertical steel plate, so that operation is fixed to the direction of close vertical steel plate, and chassis is walked on horizontal steel plate.(for example Japanese patent laid-open 5-169256 communique).

But when upright rib welded, the direction of travel of chassis was on vertical direction Z, so vertical guide stem or the vertical guide rail that makes chassis can move usefulness in vertical direction will be arranged.Because the moving direction of this guide rail restriction chassis, if use aforementioned feeler mechanism, then total becomes ground in parallel (and in vertical direction) fixed guide in quadrature and in fact vertical two block plates one, profiling platform parallel with this steel plate and that can advance and retreat with respect to another steel plate is installed on chassis, and at this upper support outstanding profiling roller and the welding torch that welds two steel plate quadrature ribs, so that contact with another steel plate.

This occasion, because of the profiling roller only carries out profiling to the surface (leaving quadrature rib position to a certain degree in the horizontal direction) of aforementioned another steel plate, so when owing to the deflection of steel plate, become folding and inclination etc. between this profiling position and quadrature rib, when on the surperficial parallel direction (the advance and retreat direction of profiling roller) of an aforementioned block plate position skew (this skew is often arranged) being arranged, the welding target location of welding torch is just departed from the quadrature rib and is departed from size and equals this position skew.

In upright rib welding, because of motlten metal flows below easily, so be difficult for transferring the width of delegation's welding bead big.Thereby, in the occasion of required weld seam broad, have to make the welding bead line number to increase, and every provisional capital to change or regulate the welding target location, so in the wide welding of weld seam, not only time-consuming but also operator's inefficiency.

The 1st purpose of the present invention is to alleviate upright rib welding operator's work and increase 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 reliable in action and all higher vertical edge welding device of durable reliability with better simply frame for movement, the 4th purpose provides than being easier to steel plate and the vertical edge welding device from wherein taking out and carrying that welding job is on-the-spot and pack into easily and will weld of packing into, and the 5th purpose is to shorten the weld interval of wide weld seam and improve operator's operating efficiency.

Operator's pull-turn button x1, pin x2c is outwards moved from the right side of sleeve x3 again after, with the rotation of knob x190 degree, remove pulling force for knob x1, pin x2c just embeds among the pin holder ditch x3b, stops slide bar x2a to be moved to the left.That is to say that piece 6 still is in move to right (keeping out of the way), compression helical spring K1 still is compressed, and slide bar x2a stops to move to left (keeping out of the way set condition).Then, counterclockwise rotate removably knob 1a, (41a 41b) opens, and behind the getaway 51, takes off chassis 1 from guide rail 51 to make the profiling roller.Then, take off guide rail 51 from right vertical panel W2.

-(a) " drive chassis downwards "-

When connecting power switch SW1, the signal lamp PL of controller C is bright, provides AC100V by power supply AC to the circuit integral body of controller C.Between the input stage of power supply AC and late-class circuit, inject fuse F1, at circuit the occasion that any unusual overcurrent flows through takes place, the protection late-class circuit.

When the operator switched manual do operation switch SW 4 to " decline " from middle position, in controller C (Fig. 7), relay coil X10 was energized, and the normal opened contact X10a of relay coil X10 connects, and normally closed contact X10b becomes disconnection.And then with switch SW 4 interlocks, the switch SW 4a of action portion within it has 4 contacts, wherein contact a3 is connected at normally closed contact pin X ₁The d side is connected to normally closed contact pin X1e side with contact a4.At this moment, if can't help change-over switch SW2 indicates (change-over switch SW2 is in the centre position) to the driving up and down of the chassis 1 of automatic welding, Yin Changkai contact pin X then _2b-X _2eAnd X _3b-X _3eDisconnect, so form direct current winding road: the lead-out terminal of speed control substrate NT W2 2. → terminal of contact pin X1d → contact a3 → contact a2 → timer contact T1 → chassis drive motor M2 → contact pin X4b → contact pin X5b → contact a1 → contact a4 → contact pin X1e → NTW2 1..Yet the lead-out terminal current potential 2. of speed control substrate NTW2 is higher than 1., so in chassis drive motor M2, electric current is to the direction shown in 2 arrow line id of usefulness shown in Figure 7 mobile (forward energising).At this moment, at normal opened contact X2e, when X3e disconnects, the normally closed contact X1Ad of relay coil X1A connects, and the normal opened contact X10a of relay coil X10 connects, the disconnection of normally closed contact X10b, thereby the motor power-on circuit of speed control substrate NTW2 will with by step-down transformer Tr1 the power supply AC by lead-out terminal 5 outputs of output channel CN1 is carried out instructed voltage after the step-down and the corresponding electric current of setting according to the resistance value of potentiometer VR2 of voltage, chassis drive motor M2 is carried out the forward energising, make motor M2 forward rotation, the pinion of engagement also is rotated in the forward on tooth bar 50, and chassis 1 descends.That is to say, utilize potentiometer VR2 to specify the decrease speed of chassis 1.Wherein, by the circuit on the substrate, the terminal of each output 1-6 of output channel CN1 and speed control substrate NTW2 1.-6. be connected.

Here, for example chassis 1 is at upper limit position, connection by means of upper limit position switch ST, relay coil X4 is energized, even normally closed relay contact pin X4b disconnects,, also set up the series circuit of manual downward driving chassis by diode D3, so chassis drive motor M2 is switched on by forward, chassis 1 descends.

When manual switch SW 4 is got back on the centre position, switch SW 4a disconnects (any line does not connect) entirely with 4 contacts that its inside has, series circuit by manual downward driving chassis disconnects, and stops the energising to motor M2, so chassis 1 stops.In addition, because of block to the alternating voltage of relay coil series circuit, so the contact pin X10a of relay 10 becomes disconnection, X10b becomes connection because of contact pin, so the terminal 5 of the output channel CN1 of speed control substrate NTW2 is with

terminal

4,3. be connected with earth terminal by terminal 3, it is invalid to be become by the instructed voltage of the current potential gauge VR2 of lead-out terminal 5 output.In addition, do not turn back to the occasion in centre position in switch SW 4 hand-manipulated, be when connecting (chassis 1 arrives lower limit) also at lower position switch SB, relay coil X5 is energized, normally closed relay contact pin X5b disconnects, series circuit by manual downward driving chassis disconnects, and stops the energising to motor M2, so chassis 1 stops.

-(b) " upwards drive chassis "-

When the operator switched manual operation switch SW4 to " rising " from middle position, X10 was energized at controller C (Fig. 7) repeat circuit coil, and the normal opened contact X10a of relay coil X10 connects, and normally closed contact X10b becomes disconnection.And then, with the switch SW 4a of switch SW 4 interlock within it portion 4 contacts are arranged, wherein contact a1 is connected to normally closed contact pin X1d side, contact a2 is connected to normally closed contact pin X1e side.At this moment, if can't help change-over switch SW2 (change-over switch SW2 is in the centre position) indicated in the driving up and down of the chassis 1 of automatic welding, then Yin Changkai contact pin X2b-X2e and X3b-X3e disconnect, so form dc loop circuit: the lead-out terminal of speed control substrate NTW2 2. → terminal of contact pin X1d → contact a1 → contact pin X5b → contact pin X4b → chassis drive motor M2 → timer node T1 → contact a2 → contact pin X1e → NTW2 1..Yet the lead-out terminal current potential 2. of speed control substrate NTW2 is higher than 1., so in chassis drive motor M2, electric current is to the direction shown in 2 arrow line iu shown in Figure 7 mobile (reverse flow).At this moment, at normal opened contact X2e, when X3e disconnects, the normally closed contact X1Ad of relay coil X1A connects, and the normal opened contact X10a of relay coil X10 connects, the disconnection of normally closed contact X10b, thereby the motor power-on circuit of speed control substrate NTW2 will with by step-down transformer Tr1 the power supply AC by lead-out terminal 5 outputs of output channel CN1 is carried out instructed voltage after the step-down and the corresponding electric current of setting according to the resistance value of potentiometer VR2 of voltage, M2 carries out reverse energising to the chassis drive motor, make motor M2 backwards rotation, also backwards rotation of meshing pinion on tooth bar 50, chassis 1 rises.That is to say, utilize potentiometer VR2 to specify the rate of climb of the chassis 1 that does not weld occasion.Wherein, the circuit on the channel substrate, the terminal of each lead-out terminal 1-6 of output channel CN1 and speed control substrate TNW2 1.-6. be connected.

Here, for example in the lower position of chassis 1, connection by means of lower position switch SB, relay coil X5 is energized, even normally closed relay section X5b disconnects,, also set up the manual series circuit that upwards drives chassis by diode D2, so chassis drive motor M2 is by reverse energising, chassis 1 rises.

When manual switch SW 4 is got back on the centre position, switch SW 4a disconnects (any line does not connect) entirely with 4 contacts that its inside has, disconnect by the manual series circuit that upwards drives chassis, stop energising, so chassis 1 stops to motor M2.In addition, because of block to the alternating voltage of relay coil series circuit, so the contact pin X10a of relay X10 becomes disconnection, X10b becomes connection because of contact pin, so the terminal 5 of the output channel CN1 of speed control substrate NTW2 is with

terminal

4,3. be connected with earth terminal by terminal 3, it is invalid to be become by the instructed voltage of the potentiometer VR2 of lead-out terminal 5 output.In addition, do not turn back to the occasion in centre position in switch SW 4 hand-manipulated, be when connecting (chassis 1 arrives upper limit) also at upper limit position switch ST, relay coil X4 is energized, normally closed relay contact pin X4b disconnects, disconnect by the manual series circuit that upwards drives chassis, stop energising, so chassis 1 stops to motor M2.

Again, the decline of aforesaid chassis 1 by means of switch SW 4 hand-manipulated/rising drives, and controller C is only in the occasion that does not enter (C) " welding " control model that then will describe or not carry out the occasion of welding rod fine motion effective.This occasion go out to be exactly: before the welding beginning or pushing under stop button PB2 (disconnection), relay coil X1 and the cold state of X1A, normally closed contact X1f connects, and not according to piezoelectricity welding rod inching button PB3, with the normally closed contact PB3a closure that the interlock back disconnects of pushing of PB3, all relay tip is in original (before the welding beginning) state.Also promptly, become the occasion of the wait state that will carry out (C) " welding ".In the control model of carrying out (C) " welding ", relay coil X1 and X1A are switched on, its normally closed contact X1f is disconnected, so even switch SW hand-manipulated 4 is received " decline " or " rising " side, can aforesaid (a) not occur and " drive chassis downwards " or (b) " upwards drive chassis " by means of switch SW 4 hand-manipulated not to relay coil X10 or switch SW 4 energisings yet.But, carry out in the control model of (C) " welding ", so while while can weld the chassis 1 or weld when vibrating welding torch T of descending, chassis 1 rises.The operation of manual operations switch SW 4 does not influence the action of any this (C) " welding ".When stopping the action of this (C) " welding ", push (disconnection) welding shutdown switch PB2.

-(C) " welding "-

Before beginning welding, operate under the situations such as changing welding rod, for the welding rod front end being delivered to the front end of welding torch T, as required, often carry out the welding rod fine motion.This occasion, during operator presses inching button PB3, X9 is energized because of relay coil, so the normal opened contact X9a of the relay coil X9 of controller C becomes closure, welding rod feeding means WS connects at the fine motion trigger.Welding rod feeding means WS delivers to welding torch T with welding rod during the fine motion trigger is connected.The operator is by means of inching button PB3, when hand leaves, inching button PB3 becomes disconnection, and block energising to relay coil X9, the normal opened contact X9a of relay coil X9 reverts to disconnection, the fine motion trigger of welding rod feeding means WS disconnects, and welding rod feeding means WS stops to give welding rod to welding torch T.When the operator carries out the welding rod fine motion before welding, as required, by means of continuing to push the front end that inching button PB3 can deliver to the welding rod front end welding torch T.

Here, present by means of the welding rod that relay coil X9 carries out, the utilization independently circuit different with the feed circuit of welding rod in the driving welding downwards hereinafter described and the driving welding that makes progress carries out, in the driving welding downwards or the driving welding that makes progress, because of normally closed contact pin X1Ab becomes disconnection (hereinafter telling about), so block energising, become that it doesn't matter to relay coil X9.Again, even described hereinafter vibroswitch SW3 receives the occasion of " leading to " side, the normally closed contact SW3a that disconnects with switch SW 3 " leading to " interlock back also disconnects, and with downward driving welding or upwards drive in the welding identically, also it doesn't matter to block energising to relay coil X9.

When the operator connects welding initialize switch PB1, relay coil X1, X1A is energized, and its normally opened relay contact pin X1a-X1c, X1g, X1Aa and X1Ac connect, and normally closed relay contact pin X1d-X1f, X1Ab and X1Ad become disconnection.Normally closed relay contact pin X1d-X1f disconnects, and the chassis that does not just respond aforementioned utilization switch SW 4 hand-manipulated drives.By means of the connection of normally opened relay contact pin X1Aa, relay coil X1, X1A is by self-sustaining (even switch P B1 reverts to disconnection, also continuing relay coil X1, X1A are switched on).Here, the normally opened relay contact pin X1a of relay coil X1, with whether to press vibroswitch SW3 irrelevant, its reason is the vibratory drive (hereinafter telling about) that must carry out welding torch T in following ((C-2) " upwards drives welding "), and this will narrate in the clauses and subclauses of following ((C-2) " upwards drives welding ").

-(C-1) " drive welding downwards "-

When the operator connects welding initialize switch PB1, if change-over switch SW2 is switched to " advancing down " side by the centre position, connection by means of normally opened relay contact pin X1Aa, at relay coil X1, X1A is by the self-sustaining while, relay coil X3 is energized, and relay contact pin (often opening) X3a-X3e connects.The connection of relay contact pin X3b-X3d, Yin Changkai contact pin X1b, X1c on and form the dc loop circuit of downward driving welding: the output of speed control substrate NTW2 2. → terminal of contact pin X1b → contact pin X3b → timer contact T1 → chassis drive motor M2 → contact pin X3d → contact pin X5b → contact pin X3c → contact pin X1c → NTW2 1..Therefore, in chassis drive motor M2, electric current flows (forward energising) to the direction shown in 2 arrow line id shown in Figure 7, and " to drive chassis downwards " identical with aforesaid (a), causes the downward driving of chassis 1.Contact pin X3d with often open contact pin X4b and be connected in parallel, it doesn't matter to drive the "on" position of the relay coil X4 that the series circuit of welding and the break-make (being the on/off of upper limit position switch ST) of often opening contact pin X4b caused downwards.

Moreover the connection of relay contact pin X1A makes the welding of source of welding current PS begin the flip-flop circuit connection, thus, and the welding of beginning welding torch T.Again, welding rod is delivered to the welding rod feeding means WS of welding torch T, response is presented control signal S1 from the welding rod that source of welding current PS comes, and welding rod is delivered among the welding torch T.

Because often opening contact pin X1g connects, relay coil X10 becomes "on" position, utilize the normal opened contact X10a of relay coil X10 to connect, normally closed contact X10b and normally closed contact pin X1Ad disconnect, it is identical that the motor power-on circuit of speed control substrate NTW2 and aforesaid (a) " drive chassis downwards ", the corresponding electric current of voltage that to set with the resistance value of the instructed voltage of lead-out terminal 5 output of output channel CN1 and current potential gauge VR2, carry out the forward energising to chassis drive motor M2, thus, motor M2 forward rotation, the pinion that meshes on tooth bar 50 is forward rotation also, and chassis 1 descends.That is to say, in driving downwards with manual operations/downward driving is irrelevant in welding, and utilizes current potential gauge VR2 to specify the decrease speed of chassis 1.This is the state that drives downwards welding, while chassis 1 descends welding torch T is provided welding rod and welds.

In this state, when pressing welding shutdown switch PB2 (disconnection), the energising of relay coil X1, X1A stops, make relay contact pin X1b, X1c, X1Aa and X1Ac return disconnection, so the welding in source of welding current PS begins in the trigger disconnection, the DC circuit that drives welding downwards disconnects.So welding stops and the decline of chassis 1 stops.The self-sustaining of the "on" position of relay coil X1, X1A also is disengaged.Normally closed contact pin X1d, X1e, X1Ab and X1Ad return original state (connection).At this moment, begin to drive the occasion of welding once more downwards in hope, if press welding beginning switch P B1 once more, then begin to drive welding once more downwards, occasion in that hope begins upwards to drive welding once more switches to " enterprising " side with change-over switch SW2, by means of pressing welding initialize switch PB1 once more, then chassis 1 carries out action hereinafter described in ((C-2) " upwards drives welding ").Manual manual operation switch SW4 also is effectively, and the operation of response manual manual operation switch SW4 can be carried out aforesaid (a) and " upwards drive chassis " or (b) " drive chassis downwards ".

Do not disconnect welding shutdown switch PB2, when disconnection switched to connection (chassis 1 arrive in lower position), because the connection of lower position switch SB, relay coil X5 was energized with lower position switch SB, normally opened relay contact pin X5a connects, and normally closed relay contact pin X5b disconnects.Utilize normally opened relay contact pin x5a to become connection, relay coil X6 is energized (because of change-over switch SW2 is switched to the D score side, so the energising of response relay coil X3, relay contact pin X3a has been in on-state), normally closed relay contact pin X6a, X6b become disconnection.Because of relay contact pin X6b disconnects, thus the energising of relay coil X1, X1A blocked, normally opened relay contact pin X1a-X1c, X1g, X1Aa and X1Ac disconnect, normally closed relay contact pin X1d-X1f, X1Ab and X1Ad return connection.

The disconnection of relay contact pin X1b-X1c and X5b, block aforementioned downward driving welding dc loop circuit (by the output of speed control substrate NTW2 2. → 1. the terminal of contact pin X1b → contact pin X3b → timer contact T1 → chassis drive motor M2 → contact pin X3d → contact pin X5b → contact pin X3c → contact pin X1c → NTW2 form) energising, the decline of chassis 1 stops.Because the disconnection of normally opened relay contact pin X1Ac, source of welding current PS stops to provide weld power to welding torch T.The self-sustaining of the "on" position of relay coil X1, X1A is disengaged, normally closed contact pin X1d, and X1e, X1Ab and X1Ad also return original state (connection).

So far, the operation that drives welding downwards finishes.Making progress in hope drives the occasion of welding, and change-over switch SW2 is switched to " enterprising " side, and by means of pressing welding initialize switch PB1 once more, chassis 1 carries out the action that (C-2) will advance to state in " upwards driving welding ".Moreover, for the operation of manual manual operation switch SW4, can only carry out aforesaid (b) and " upwards drive chassis ".

-(C-2) " upwards drive welding "-

Wishing to make progress drives the occasion of welding (Vibration Welding), and the operator switches to " enterprising " side with change-over switch SW2, presses welding initialize switch PB1.When the operator connects welding initialize switch PB1, relay coil X1, X1A is energized, its normally opened relay contact pin sheet X1a-X1c, X1g, X1Aa and X1Ac connect, and normally closed relay contact pin X1d-X1f, X1Ab and X1d become disconnection.Normally closed relay contact pin X1d-X1f disconnects, and does not just respond aforementioned chassis by switch SW 4 hand-manipulated and drives.Because the connection of normally opened relay contact pin X1Aa is even relay coil X1, X1A are by self-sustaining (, also continuing to relay coil X1 the X1A energising even switch P B1 returns disconnection).When change-over switch SW2 is switched to " enterprising " side by the centre position, the normal open switch SW2a that connects with change-over switch SW2 being switched to the interlock of " enterprising " side becomes connection, block energising simultaneously to relay coil X3, the normally opened relay contact pin X3a of relay coil X3 returns disconnection, blocks the energising of relay coil Xb.In this state, if the operator connects welding initialize switch PB1, then the normally closed relay contact pin X6a of relay coil X6 returns connection, because the connection of the normally opened relay contact pin X1a of relay coil X1, relay coil X7 is energized.Thus, the relay contact pin X7a that often opens becomes connection, and normally closed relay contact pin X7b becomes disconnection.Because the connection of normally opened relay contact pin X7a, by normally closed relay contact pin RY1a, to relay coil X8 indirect current stream, the section X8a-X8c that often opens of relay coil X8 becomes connection, and normally closed contact pin X8d, X8e become disconnection.Relay coil X8 is owing to often open the connection of contact pin X8a, keep "on" position, contact pin X8a is the self-sustaining contact of relay coil X8, when often opening contact pin X8b, X8c connection and normally closed contact pin X8d, X8e disconnection, terminal by speed control substrate NTW1 2., 5., size and the internal circuit of controller C are adorned the corresponding electric current of voltage of variable resistance VR1, fixed resister R1 and fixed resister R2 setting, vibrating motor M1 forward is switched on, this vibrating motor is just changeed, and welding torch T carries out aforesaid vibration.

That is to say that the vibration velocity of welding torch can be specified by variable resistance VR1.Fixed resister R1 and fixed resister R2 are the adjustment resistors that prevents that the variable amplitude of variable resistance VR1 from becoming excessive.The terminal of the earth terminal of transformer Tr1 and NTW1 2. between, insert fuse NFB, any unusual, occasion of flowing through overcurrent takes place in circuit, the circuit of protection speed control substrate NTW1.

The vibration of aforesaid welding torch T only is switched to " enterprising " side (switch SW 2 is connected) at change-over switch SW2 from middle position, carry out when pressing welding initialize switch PB1 or vibroswitch SW3.

Again, be switched to " enterprising " side at change-over switch SW2, when pressing welding vibroswitch SW3 again, chassis 1 does not weld and driving own, only drives the vibration of welding torch.

When the operator connects welding initialize switch PB1, if change-over switch SW2 is switched to " enterprising " side by the centre position, then because the connection of normally opened relay contact pin X1Aa, at relay line chart X1, X1A is by the self-sustaining while, to relay coil X2 energising, relay contact pin (often opening) X2a-X2e connects.Relay contact pin X2b-X2d connects, connect by means of often opening contact pin X1b, X1c, formation by the lead-out terminal of speed control substrate NTW2 2. → terminal of contact pin X1b → contact pin X2b → contact pin X2d → contact pin X4b → chassis drive motor M2 → timer contact T1 → contact pin X2c → contact pin X1c → NTW2 1. form upwards drive the welding dc loop circuit, in chassis drive motor M2, electric current is to the direction shown in 2 arrow line iu shown in Figure 7 mobile (reverse flow).Cause the rising of chassis 1 to drive.

Contact pin X2d with often open contact pin X5b and be connected in parallel, it doesn't matter upwards to drive the "on" position of the relay coil X5 that the series circuit of welding and the break-make (being the on/off of lower position switch SB) of often opening contact pin X5b cause.Moreover, the connection of relay contact pin X1Ac, the welding of connecting source of welding current PS begins flip-flop circuit, thus, the welding of beginning welding torch T.In addition, welding torch T is presented the welding rod feeding means WS of welding rod, response is presented control signal S1 from the welding rod that source of welding current PS comes, and welding rod is sent among the welding torch T.

Because often open the connection of contact pin X1g, relay coil X10 becomes "on" position, the normal opened contact X10a of relay coil X10 connects, and normally closed contact X10b and normally closed contact pin X1Ad become disconnection.And, normal opened contact X2a is by the energising of relay coil X2 ON (connection), so motor power-on circuit of speed control substrate NTW2, with the instructed voltage of size and lead-out terminal 5 output of output channel CN1 with by the corresponding electric current of voltage of the resistance value setting of the variable resistor VR3 that adorns in the resistance value of potentiometer VR2, the controller C internal circuit, chassis drive motor M2 forward is switched on.Thus, motor M2 just changes, and pinion meshing on tooth bar 50 reverses, and chassis 1 rises.That is to say that chassis 1 is in the rate of climb that upwards drives in the welding, upwards drive differently that except that the resistance value of potentiometer VR2, the resistance value of the variable resistance VR3 that is increased reduces speed with manually-operated.This is the state that upwards drives in the welding, and chassis 1 rises with low speed on one side, vibratory drive welding torch T in carries welding rod on one side, and weld.

At this state, when pressing welding shutdown switch PB2 (disconnection), the energising of relay coil X1, X1A stops, because of relay contact pin X1b, X1c, X1Aa and X1Ac return disconnection, so the welding in source of welding current PS begins in the trigger disconnection, upwards drive the welding dc loop circuit and disconnect.So welding stops and the rising of chassis 1 stops.The self-sustaining of the "on" position of relay coil X1, X1A is disengaged.Normally closed contact pin X1d, X1e, X1Ab and X1Ad return original state (connection).

Again, the energising of slew relay coil X1, Yin Changkai contact pin X1a becomes disconnection, so the energising of relay coil X7 stops, often opening contact pin X7a becomes disconnection, normally closed contact pin X7b becomes connection.Here, relay coil X8 utilizes its self-sustaining contact X8a, keeps "on" position, often opens contact pin X8a-X8c and connects, and normally closed contact pin X8d, X8e keep off-state.That is to say, keep the energising of vibrating motor M1, welding torch T continues vibration.

Owing to often open the connection of contact pin X8a and the connection of normally closed contact pin X7b, timer T1 is energized, and picks up counting yet on the other hand.When the timing of timer T1 end setup time T 1 when (surpassing regularly), timer T1 connects timer contact pin T1a.In this state, when the amplitude central portion of sensor PX1 perception welding torch T in adding vibration, the link output L level of timer contact pin T1a.In relay coil RY1, by rectification circuit Rec1, add, and make relay coil Ry1 energising by timer contact pin T1a to the DC voltage behind the ac voltage rectifier that comes among the transformer Tr1.Diode D1 is used for protective relay coil Ry1, and electrolytic capacitor C1 is used for exchanging and dams.By means of relay coil Ry1 is switched on, the normally closed contact pin Ry1a of relay coil Ry1 becomes disconnection, blocks the logical Mian to relay coil X8, and the contact pin X8a-X8c that often opens of on-state disconnects, and normally closed contact pin X8d, X8e return on-state.That is to say that block the energising to vibrating motor M1, vibrating motor M1 stops, welding torch T be parked in add the amplitude central portion of vibration.

Upwards drive the occasion of welding once more in hope,, then begin upwards to drive the vibratory drive of welding and welding torch T once more if press welding initialize switch PB1 once more; Drive the occasion of welding once more downwards in hope, change-over switch SW2 is switched to " advancing down " side, by means of pressing welding initialize switch PB1 once more, chassis 1 carries out aforesaid action downwards in ((C-1) " drives and weld ").Manual manual operation switch SW4 also is effectively, and the operation of response manual manual operation switch SW4 is carried out aforesaid (a) and " upwards driven chassis " and (b) " drive chassis downwards ".

Constantly snap and meet shutdown switch PB2, when disconnection switched to connection (chassis 1 arrive in upper limit position), because the connection of upper limit position switch ST, relay coil X4 was energized with upper limit position switch ST, normally opened relay contact pin X4a connects, and normally closed relay contact pin X4b disconnects.Utilize normally opened relay contact pin X4a to become connection, relay coil X6 be energized (because of change-over switch SW2 be switched to " on " side, so in response to the energising of relay coil X2, relay contact pin X3a has been in on-state), normally closed relay contact pin X6a, X6b become disconnection.Because of relay contact pin X6b disconnects, thus the energising of relay coil X1, X1A blocked, normally opened relay contact pin X1a-X1c, X1g, X1Aa and X1Ac disconnect, normally closed relay contact pin X1d-X1f, X1Ab and X1Ad return connection.

Relay contact pin X1b-X1c and X4b disconnect, just block aforementioned upwards drive the welding dc loop circuit (by the lead-out terminal of speed control substrate NTW2 2. → 1. the terminal of contact pin X1b → contact pin X2b → contact pin X2d → contact pin X4b → chassis drive motor M2 → timer contact T1 → contact pin X2c → contact pin X1c → NTW2 form) energising, the rising of chassis 1 stops.Because the disconnection of normally opened relay contact pin X1Ac, the weld power that provides to welding torch T is provided source of welding current PS, simultaneously by the disconnection of the normally closed contact pin X6a of relay coil X6, stop energising to relay coil X7, so identical when pressing stop button PB2, the vibration of welding torch T stops at the amplitude central portion of welding torch T vibration.

So far, the operation that upwards drives welding finishes.Drive the occasion of welding downwards in hope, change-over switch SW2 switched to " advancing down " side, by means of pressing welding initialize switch PB1 once more, chassis 1 carry out (C-1) " drive welding downwards " in the action stated of preamble.Moreover, for the operation of manual manual operation switch SW4, can only carry out aforesaid (a) and " drive chassis downwards ".

Below, summary is listed the feature of previous embodiment.

(1) fixed guide 51 is on rail brackets 60a, 60b, make surface become 45 degree for right vertical panel W2, and each lever (56b) of these supports is made level, made their front end contact with the surface of left vertical panel W1 and guide rail 51 is fixed on the right vertical panel W2, thereby guide rail 51 becomes institute's set a distance with parallel with respect to left and right vertical plate W1, W2, and the platen surface of guide rail 51 becomes 45 degree with respect to left and right vertical plate W1, W2.

When on guide rail 51 chassis 1 being installed, the longitudinal axis extension line of the 1st rocking arm y1 is automatically in fact crossing with welding datum line Lw.That is to say, the longitudinal axis of the 1st rocking arm y1, for left and right vertical plate W1, W2 become 45 degree and with welding datum line Lw quadrature in fact.Support profiling roller y7 by profiling rocking arm y6 with the 2nd rocking arm y3, because of the 2nd rocking arm y3 and the 1st rocking arm y1 almost parallel, so profiling roller y7 is opposed with welding datum line Lw reality automatically.

Collapse coil spring K1 pushes the 1st rocking arm in the direction near welding datum line Lw, so profiling roller y7 enters while and left and right vertical plate W1, W2 position contacting, promptly has the inside of the angle of cut of welding datum line Lw.That is to say the left and right vertical plate W1, the W2 that automatically push down this angle of cut.

(2) suppose that because the bending of left and right vertical plate W1, W2 etc., the 1st rocking arm y1 is not 45 degree with respect to left and right vertical plate W1, W2.Even this occasion, because can cross the axostylus axostyle y2 that extends in the Z direction, the 2nd rocking arm y3 can rotate with respect to the 1st rocking arm y1, also because collapse coil spring K1 pushes as described above, so the 2nd rocking arm y3 rotates, make profiling roller y7 enter while position contacting, promptly have the inside of the angle of cut of welding datum line Lw with left and right vertical plate W1, W2.

Thus, the profiling of the angle of cut (rib) of chassis 17 pairs of left and right vertical plates of profiling roller W1, W2 during the Z direction moves (welding datum line Lw) is correct.

Because of by the 3rd rocking arm y4 with the 2nd rocking arm y3 supporting welding torch T, so draw and track (but becoming the motion track of profiling roller y7 parallel mobile) that the profiling motion track of profiling roller y7 is practically identical in the welding target location of welding torch T.Therefore, the welding position of welding torch T in the Z of chassis 1 direction moves, Lw is correct for the welding datum line.Even left and right vertical plate W1, W2 have bending etc., and welding datum line Lw bending also can obtain correctly and then welding the long stable weld seam that equates (amplitude is even) of datum line and leg, and improves welding quality.

(3) the adjustment knob y14 of operation y direction guiding mechanism 20Y can be at the track of y direction adjustment with respect to the welding target location of the welding torch T of the profiling motion track (welding datum line Lw) of profiling roller y7.For example, when finishing welding with delegation's weldering, can make the track of the welding target location of welding torch T in the same manner with the profiling motion track (welding datum line Lw) of profiling roller y7, and when finishing welding with 2 row welding beads, can be predetermined the welding target location (with the y direction position of welding datum line Lw) of welding torch T in each welding bead, again each welding bead be adjusted the welding target location (y direction) of welding torch T as benchmark.Therefore, in the occasion of many welding bead welding, even welding datum line Lw bending also can obtain correctly welding datum line and the long stable weld seam that equates (amplitude is even) of leg with first, and improve welding quality.

(4) because make on chassis 1 and can support the 1st rocking arm y1 movably at directions X, with the 1st rocking arm supporting profiling roller y7 and welding torch T, with collapse coil spring K1, slide bar X2a and knob X1 with profiling position retreating position on set the 1st rocking arm y1, so set profiling position and the retreating position of profiling roller y7 and welding torch T easily.

When adopting the profiling set positions, because of collapse coil spring K1 pressurizes to profiling roller y7 profiling, that is to say, because of with driving to the profiling position of the 1st rocking arm y1, profiling pressurization ground common compression coil spring is so it is simple, simple in structure and reliability is high to be used to set the combination of the mechanism of profiling position/retreating position and feeler mechanism.

(5) because of rotating removably knob 1a, can unload heavier chassis 1 from long guide rail 51 or chassis 1 is installed at guide rail 51, for example, when finishing the welding in certain place, can unload chassis 1 earlier, after guide rail 51 is transported to next welding place and sets, conveying trolley 1 (and welding rod feeding means) again, be installed on the guide rail 51, thus the carrying of guide rail 51 and be set to the welding place all be not difficult.

(6) chassis 1 is being positioned at upper limit position (perhaps lower position), and the operator is when connecting welding initialize switch PB1, controller C automatically begins to weld and carry out the downward driving of chassis 1.When being welded to lower position (upper limit position), automatically stop to weld and stopping the downward driving (upwards driving) of chassis 1, wait for operator's indication (switching manipulation), look after welder so the operator needn't follow the tracks of frequently, and many welders of use that can walk abreast.Thus, can improve operator's operating efficiency.

(7) except that welding initialize switch PB1 and welding shutdown switch PB2, also have the manual manual operation switch SW4 that manually-operated is used, when the operator is switched to the decline side with this artificial console switch SW4, controller C drives chassis 1 downwards, and lower position switch SB is according to the arrival of chassis 1, switch to connection from disconnection, perhaps before manual manual operation switch SW4 turns back to the centre position, carry out the downward driving of chassis 1.Equally, when the operator was switched to uplifted side with manual manual operation switch SW4, controller C upwards drove chassis 1, and limit switch ST is according to the arrival of chassis 1, switch to connection from disconnection, perhaps before manual manual operation switch SW4 turns back to the centre position, carry out upwards driving of chassis 1.Because above-mentioned functions is added no power in welding torch T at this moment, so the walking running that easy realization is wanted the welding end position of prior confirmation Z direction and welded the chassis 1 of starting position.

(8) except that the function of aforementioned (7), also increase with respect to guide rail 51 and regulate freely in the Z direction, be used for from being disconnected to upper and lower switch striker SRT and the SRB of connection upper limit position switch ST and lower position switch SB, in aforementioned (7), make chassis 1 stop and connecting on the position of lower position switch SB at the welding end position, fixing switch striker SRB down makes chassis 1 stop in the welding starting position and is connecting on the position of upper limit position switch ST and fix switch striker SRT.Therefore, can determine the welding starting position and the welding end position of Z direction.Operating based on the Visual Confirmation of the welding target location of current welding torch T like this, is easy and real to the operator.

(9) because of selecting not Vibration Welding (advancing welding down) and Vibration Welding (enterprising welding), again because of the operator in conjunction with desired welding condition (particularly wanting weld width), can select and make up effective bond pattern (friction is arranged), so can realize desired welding with high operating efficiency.Because of adjusting amplitude, can adjust the welding target location with knob 131a with knob y14, thus can high-freedom degree selection and Combination Welding pattern (friction is arranged), and realize desired welding with high operating efficiency.Vibrating mechanism 100 not only with the direction of trolley running direction Z quadrature, and also synchronously vibrate welding torch T with y direction vibration at vertical direction Z, make the input uniform heat distribution of mother metal (steel plate) and motlten metal, so reduce the possibility that hangs of low melt metal, and can obtain welding bead to the complete high-quality welding seam of the good weld bead shape of the fusion of mother metal.
