[0039] The utility model will be described in detail below in combination with the embodiments shown in the drawings. However, the embodiments do not limit the utility model, and the changes in mechanism, method or function made by those skilled in the art based on the embodiments are all included in the protection scope of the utility model.
[0040] The terms for indicating spatial relative positions such as "upper", "lower", "left", "right", "front", "back", etc. used in the present text are used for the purpose of convenient description to describe the relationship of one feature relative to another feature as shown in the drawings. It can be understood that the terms for indicating spatial relative positions can be intended to include different positions other than the positions shown in the drawings according to the different positions of the product, and should not be understood as limiting the claims. In addition, the descriptive word "horizontal" used in the present text is not completely equivalent to along the direction perpendicular to the direction of gravity, and a certain angle of inclination is allowed.
[0041] As shown in Figures 1-6 An embodiment of the present application provides a welding device 100, which comprises a wire feeding device 10 for conveying welding wire and a welding head 20 arranged on one side of the wire feeding device 10. When welding a workpiece, the welding head 20 welds a weld on the workpiece along a predetermined track, and in the process of welding, the wire feeding device 10 moves along with the welding head 20 to convey welding wire into the weld of the workpiece. Under the action of the welding head 20, the welding wire can be fused with the workpiece, so as to achieve the purpose of optimizing the internal organization morphology of the weld and improving the overall performance of the weld. In the embodiment, the welding head 20 is preferably a laser welding head, which can emit laser to irradiate the molten welding wire, so as to perform welding.
[0042] Specifically, the wire feeding device 10 comprises a box seat 1, a sliding block 2 and a sliding seat 3 movably connected to the box seat 1 along a first direction, an elastic member 4 arranged between the sliding block 2 and the sliding seat 3, the elastic member 4 elastically abutting against the sliding seat 3 and the sliding block 2 along the first direction. The wire feeding device 10 further comprises a driving member 5 and a wire feeding nozzle 6, the driving member 5 being connected to the box seat 1 and the sliding block 2 and used for driving the sliding block 2 to move relative to the box seat 1 along the first direction, and the wire feeding nozzle 6 being connected to the sliding seat 3 and capable of moving along the first direction following the sliding seat 3. Figure 2 The arrow in the figure shows the first direction. In the embodiment, the first direction can be regarded as the up-down direction.
[0043] When the welding equipment 100 is in operation, the driving member 5 can drive the sliding seat 3 to move along the first direction according to different welding positions, the strength of the welding wire itself and the like, so that the sliding seat 3 drives the wire feeding nozzle 6 to move to a suitable position. Then, the welding wire sent out by the wire feeding nozzle 6 can abut against the surface of the workpiece to be welded, and under the action of the elastic member 4, the welding wire can move along the first direction according to the surface condition of the workpiece to be welded, so that the deformation of the welding wire can be reduced as much as possible during the welding process, and the purpose of stable welding can be achieved.
[0044] The sliding block 2 is substantially in the shape of a "U" character, and comprises a first abutting portion 21 and a second abutting portion 22 arranged at intervals along the first direction, and a connecting portion 23 connecting the first abutting portion 21 and the second abutting portion 22, wherein the connecting portion 23 is movably connected to the box seat 1 along the first direction.
[0045] The sliding seat 3 comprises a third abutting portion 31 arranged between the first abutting portion 21 and the second abutting portion 22, and the elastic member 4 comprises two elastic members, i.e., a first elastic member 41 and a second elastic member 42, the first elastic member 41 elastically abutting against the first abutting portion 21 and the third abutting portion 31 along the first direction, and the second elastic member 42 elastically abutting against the third abutting portion 31 and the second abutting portion 22 along the first direction.
[0046] With the above arrangement, as shown in the figure, no matter whether the sliding seat 3 moves upward or downward, one elastic member 4 will be compressed and the other elastic member 4 will be stretched, so that the wire feeding nozzle 6 can move bidirectionally along the first direction under the action of the first elastic member 41 and the second elastic member 42. Figure 2
[0047] The welding equipment 100 further comprises a connecting rod 7, the connecting rod 7 being connected to the second abutting portion 22 and the output end of the driving member 5 and passing through the third abutting portion 31 and the first abutting portion 21, i.e., the driving member 5 is connected to the sliding block 2 through the connecting rod 7. The first elastic member 41 and the second elastic member 42 are both sleeved on the periphery of the connecting rod 7, and the connecting rod 7 plays a role of limiting the positions of the first elastic member 41 and the second elastic member 42.
[0048] In the embodiment, the first elastic member 41 and the second elastic member 42 are both spiral springs. In other embodiments, the first elastic member 41 and the second elastic member 42 can also be other structures with elasticity.
[0049] When the welding device 100 is welding, if the welding wire is to be withdrawn to the end of the weld, the wire feeder 6 needs to be kept fixed during the process of withdrawing the welding wire. If the wire feeder 6 can still float in the first direction under the action of the elastic member 4, the withdrawal sticking phenomenon will occur during the process of withdrawing the welding wire. To solve the above problem, in the embodiment, the welding device 100 further comprises a limiting structure 30 for limiting the relative position between the sliding seat 3 and the box seat 1. Under the action of the limiting structure 30, the position of the sliding seat 3 will be kept fixed relative to the box seat 1, so that the wire feeder 6 cannot move in the first direction when the welding wire is withdrawn.
[0050] Specifically, the limiting structure 30 comprises a clamping shaft 301 connected to the sliding seat 3 and a clamping member 302 connected to the box seat 1 and used for clamping the clamping shaft 301. The clamping member 302 is fixedly arranged relative to the box seat 1, and when the clamping member 302 clamps the clamping shaft 301, the sliding seat 3 cannot move, and when the clamping member 302 releases the clamping shaft 301, the sliding seat 3 can move in the first direction.
[0051] The above-mentioned clamping member 302 can be a pneumatic clamping member controlled in a pneumatic manner, and the above-mentioned driving member 5 can be a telescopic pneumatic cylinder, i.e., both are controlled in a pneumatic manner. In other embodiments, the limiting structure 30 can also adopt other forms, not limited to the above-mentioned clamping member 302 and clamping shaft 301.
[0052] The sliding seat 3 is connected to the wire feeder 6 through the connecting structure 8, which comprises an adjusting assembly 81 connected to the wire feeder 6 and a connecting assembly 82 connected between the adjusting assembly 81 and the sliding seat 3. The adjusting assembly 81 is used for adjusting the position of the wire feeder 6 relative to the box seat 1, and by adjusting the adjusting assembly 81, the position of the wire feeder 6 relative to the box seat 1 can be changed, so that the wire feeder 6 can be in a better position to feed the welding wire. The connecting structure 8 is slidably connected to the box seat 1 in the first direction, and between the connecting structure and the sliding seat 3, it is specifically connected through a ball bearing 9, so that the connecting structure 8 can rotate relative to the sliding seat 3, so that the connecting structure 8 can be prevented from being stuck when sliding in the first direction.
[0053] The adjusting assembly 81 comprises a first connecting block 811 connected to the connecting assembly 82, a second connecting block 812 for connecting the wire feeding nozzle 6, and a first adjusting structure 813 formed between the first connecting block 811 and the second connecting block 812. The first adjusting structure 813 is used to adjust the relative position between the first connecting block 811 and the second connecting block 812 in a second direction. The second direction is perpendicular to the first direction. By adjusting the first adjusting structure 813, the relative position between the first connecting block 811 and the second connecting block 812 in the second direction can be changed. Thus, the position of the wire feeding nozzle 6 relative to the box seat 1 in the second direction can also be changed.
[0054] Specifically, the first adjusting structure 813 comprises a mounting hole 8131 formed on the first connecting block 811 and a slot 8132 formed on the second connecting block 812. The slot 8132 extends in the second direction, and the slot 8132 and the mounting hole 8131 are connected by a fastener (not shown in the figure). The slot 8132 specifically extends in the second direction, and the extension length is greater than the diameter of the mounting hole 8131. The fastener can move in the second direction in the slot 8132. When the relative position of the first connecting block 811 and the second connecting block 812 in the second direction is adjusted, the first connecting block 811 and the second connecting block 812 can be fixed by connecting the slot 8132 and the mounting hole 8131 through the fastener.
[0055] In the embodiment, the mounting hole 8131 is a threaded hole, and the fastener is a screw matched with the threaded hole. The screw is screwed into the threaded hole to press the second connecting block 812 against the first connecting block 811. At this time, the positions of the first connecting block 811 and the second connecting block 812 are fixed. When it is necessary to adjust the relative position of the first connecting block 811 and the second connecting block 812 in the second direction, the screw can be loosened. Figure 5 The arrow in the figure shows the second direction.
[0056] The second connecting block 812 is formed with a second adjusting structure 814. The second adjusting structure 814 is used to adjust the relative position between the wire feeding nozzle 6 and the second connecting block 812 in the axial direction of the wire feeding nozzle 6. That is, by adjusting the second adjusting structure 814, the relative position between the wire feeding nozzle 6 and the second connecting block 812 in the axial direction of the wire feeding nozzle 6 can be adjusted. The axial direction of the wire feeding nozzle 6 is arranged at an angle to the first direction.
[0057] Specifically, the second adjusting structure 814 includes a fixing hole 8141 and a cutout 8142, the fixing hole 8141 and the cutout 8142 penetrate the second connecting block 812 along the axial direction of the fixing hole 8141, and the cutout 8142 penetrates the outer sidewall of the second connecting block along the radial direction of the fixing hole 8141. The second adjusting structure 814 further includes a threaded hole 8143 and a through hole 8144 located on both sides of the cutout 8142 respectively, and a screw (not shown in the figure) connecting the threaded hole 8143 and the through hole 8144.
[0058] When the wire feeding nozzle 6 is installed, it penetrates the fixing hole 8141 and is surrounded by the sidewall of the fixing hole 8141. When the screw connecting the threaded hole 8143 and the through hole 8144 is not tightened, the wire feeding nozzle 6 can move along the axial direction of the fixing hole 8141 to adjust the position in the fixing hole 8141. When the wire feeding nozzle 6 is adjusted to the appropriate position, the screw connecting the threaded hole 8143 and the through hole 8144 is tightened, so that the sidewall of the fixing hole 8141 tightly holds the wire feeding nozzle 6, and the position of the wire feeding nozzle 6 is fixed.
[0059] In summary, when the welding equipment 100 works, the driving member 5 can drive the sliding seat 3 to move along the first direction according to different welding positions, the strength of the welding wire itself and the like, so that the sliding seat 3 drives the wire feeding nozzle 6 to move to the appropriate position. Then, the welding wire sent out by the wire feeding nozzle 6 can abut against the surface of the workpiece to be welded, and under the action of the elastic member 4, the welding wire can move along the first direction according to the surface condition of the workpiece to be welded, so as to minimize the deformation of the welding wire in the welding process, and thus the purpose of stable welding is achieved.
