Embodiment mono-
Referring to Fig. 3~Fig. 5, this embodiment discloses a kind of welding system, described welding system is used for welding closing end component 100, referring to Fig. 1 and Fig. 2,, described closing end component 100 comprises end socket 110, spindle nose 120 and gusset 130, described spindle nose 120 runs through described end socket 110 bottoms, described gusset 130, between described spindle nose 120 and described end socket 110 inwalls, plays booster action.
Described closing end component 100 volumes are larger, and as more than end socket diameter is generally 3m, required action space is very large, and closing end component 100 structure out-of-flatnesses, is difficult to clamping.For realizing the automatic welding of the closing end component 100 with These characteristics, the welding system that this embodiment provides is set to, and this welding system comprises positioner 200 and fixed welding robot 300, and:
Described positioner 200 and relative the arranging of described fixed welding robot 300, be provided with clamping tool 400 between described positioner 200 and described fixed welding robot 300; When concrete welding, described closing end component 100 is lifted on clamping tool 400 places between described positioner 200 and described fixed welding robot 300, and with the placement of the vertical state of spindle nose level, end socket, be clamped in the both ends of spindle nose by clamping tool 400, realize fixing closing end component 100, for realizing, described positioner 200 orders about described closing end component 100 by clamping tool 400 and rotates; And the scheme that clamps by trunnion axis head status in conjunction with transverse jig, has significantly reduced the spacing of described positioner 200 and described fixed welding robot 300, has dwindled working space.
Described positioner 200 and described fixed welding robot 300 are separately fixed on pedestal 500, on described pedestal 500, have groove 510, and described groove 510 is between described positioner 200 and described fixed welding robot 300; While being the level of state because of spindle nose, when concrete operation, spindle nose is positioned at the height a little more than pedestal 500, and radially taking up room at vertical direction of end socket is larger, for this reason, the latter half of end socket is placed in groove 510, and pedestal 500 can be set to roughly wait be above the ground level, or directly adopt ground as pedestal 500, in the groove 510 that vertically the nearly half height of the end socket of state locates below ground level, significantly reduce the duty space of short transverse more than ground, further dwindled working space.The degree of depth of described groove 510 is greater than the radius of described end socket, prevents that end socket avris from touching bottom land, and has influence on the rotation of closing end component 100.
To sum up, under the comprehensive function of above-mentioned clamping and groove, solved closing end component 100 clamping difficulties and taken the problem that working space is large.On this basis, described fixed welding robot 300 probes in end socket chamber from the end direction of spindle nose, orders about under the mating reaction that described closing end component 100 rotates at positioner 200, realizes the weld job of locating for the gusset of closing end component 100 etc.
Fixed welding robot 300, by corresponding computer control mechanical arm action, and then drives the welding gun of upside-down mounting to implement automatic welding, and this is prior art, is not described in detail herein.
Separately, in this embodiment, described clamping tool 400, on the one hand for realizing the clamping to closing end component 100, on the other hand for transmitting the spinning movement of positioner 200, for realizing above-mentioned two objects, and for simplified apparatus as far as possible, control cost, referring to Fig. 5, described clamping tool 400 is preferably set to, described clamping tool 400 comprises main jacking mechanism 410, secondary jacking mechanism 420 and scroll chuck 430, described scroll chuck 430 and described main jacking mechanism 410 are arranged on respectively on described positioner 200, and can order about rotation by described positioner 200, described secondary jacking mechanism 420 is rotating to be arranged on described fixed welding robot 300.
Particularly: described main jacking mechanism 410 is oppositely arranged with described secondary jacking mechanism 420, is respectively used to hold out against the both ends of described spindle nose, for realizing the clamping to spindle nose; Preferably, described main jacking mechanism 410 and described secondary jacking mechanism 420, be set to respectively bore rod structure, answer in contrast, circle centre position at described spindle nose both ends is provided with blind hole, described main jacking mechanism 410 and described secondary jacking mechanism 420 can fast inserted in described blind hole, be convenient to locate fast and hold out against.
Described scroll chuck 430 is for clamping the end of described spindle nose, and the circle centre position of described scroll chuck 430 has through hole, and described main jacking mechanism 410 is arranged in described through hole; After described main jacking mechanism 410 holds out against the both ends of described spindle nose with described secondary jacking mechanism 420, described scroll chuck 430 clamps the end edge edge of described spindle nose, and tighten, to realize described scroll chuck 430 and described spindle nose synchronization action, and then realize positioner 200 and order about closing end component 100 and rotate.
When the concrete operation of this embodiment:
1, end socket, spindle nose and gusset spot welding are fixed as one, affixed one-tenth closing end component 100, i.e. state shown in Fig. 1 and Fig. 2.
2, by closing end component 100, with the state of spindle nose level, lifting is between described positioner 200 and described fixed welding robot 300, and now, the nearly half volume of end socket is positioned at described groove 510.
3, clamping tool 400 is fixed the two ends of spindle nose, and then realizes being fixedly clamped of closing end component 100.
4, probeed in the chamber of end socket by fixed welding robot 300, weld seam between end socket, spindle nose, gusset is welded, by after having welded compared with the weld seam of Jia Hanjiejiaoduchu, positioner 200 orders about closing end component 100 and rotates to an angle, then continues welding; Or, probeed in the chamber of end socket by fixed welding robot 300, coordinate the rotation of positioner 200, rotate closing end component 100 while weld.
5, if needed, can complete after the inside weld of chamber in welding removal clamping tool 400, closing end component 100 is sling, and level is adjusted turnback, and clamping tool 400 clamps fixing spindle nose again, make the back side of end socket towards fixed welding robot 300, the weld seam of the bottom to end socket welds.
Embodiment bis-
Referring to Fig. 6~Fig. 8, this embodiment provides a kind of welding system.This embodiment is the further improvement on the basis of embodiment mono-, and the disclosed technical scheme of embodiment mono-also belongs to this embodiment, and embodiment mono-disclosed technical scheme is no longer repeated in this description.
For the welding between end socket bottom (side of evagination) and spindle nose, and other position welding of bottom, need to, after completing the step 4 of embodiment mono-, by closing end component 100 Rotate 180 degree, make end socket bottom weld towards fixed welding robot 300.This scheme need to take the resource of the welding system of too much embodiment mono-, cause the waste of resource, and the resources costs of the welding system of embodiment mono-is relatively high, cause certain waste, and, in embodiment mono-, the nearly half volume of closing end component 100 is positioned at groove 510, sling and the operation of Rotate 180 degree comparatively loaded down with trivial details.Based on this, in order further to improve the operating efficiency welding for closing end component 100, this embodiment is on the basis of embodiment mono-, set up the welding equipment for end socket bottom, certainly, if needed, the welding equipment of setting up also can be for welding in the chamber of welding closing end component 100.
