Description

Technical Field

[0001] The invention relates to the technical field of welding gun wire feeding mechanisms, in particular to a welding gun wire feeding mechanism with freely adjustable angles. Background Art

[0002] The wire feeding mechanism is mainly suitable for the double shield welding operation. The double shield welding machine needs to use a nozzle welding gun and an extended nozzle to melt the welding wire delivered to the top area of ​​the workpiece, and use carbon dioxide gas as the welding shielding gas. During the welding process, carbon dioxide gas is ejected from the welding gun nozzle to form a protective layer to isolate the adverse effects of oxygen, nitrogen, etc. in the air on the molten pool and arc, thereby obtaining high-quality welds. The existing two-way welding machine mainly adopts two ways of welding wire in actual operation. The first way is manual delivery, and the second way is a drag wire feeder. Obviously, the first way consumes a lot of physical strength of the workers and has low work efficiency. In the second way, the drag wire feeder needs to be pre-installed with the wire guide tube and welding gun of a specific pipeline. The drag welding machine continuously delivers the welding wire along the wire guide tube before it can cooperate with the welding gun to perform welding operation on the workpiece. However, this method is too bulky and will cause certain damage to the worker's wrist as the working time increases. In addition, the wire guide tube is connected to the drag wire feeder, which will occupy a certain amount of welding space.

[0024] The welding wire stabilizing mechanism 300 includes a sleeve 310, a movable sleeve 320 movably mounted in the sleeve 310, and a bellows 350 fixedly mounted at the other end of the movable sleeve 320; The welding wire advancing mechanism 400 includes a delivery sleeve 410 fixedly mounted on the other end of the corrugated tube 350, a frame plate 4103 fixedly mounted on the delivery sleeve 410, an adapter 4104 fixedly mounted on the frame plate 4103, a wire release sleeve 450 fixedly mounted on the other end of the adapter 4104, and a heat insulating sleeve 4502 inserted into the wire release sleeve 450. Two end caps 4102 are fixedly mounted on both sides of the delivery sleeve 410. The alignment assembly 500 includes a bracket 510, two third bolts 520 inserted into the bracket 510, and two wire drawing wheels 530 movably mounted on the inner side of the bracket 510. The lateral angle adjustment mechanism 600 includes a second housing 670 fixedly mounted on the bottom of the movable sleeve 320, a second motor 6701 fixedly mounted within the second housing 670, a crankshaft 660 fixedly mounted on the second motor 6701, two slides 640 disposed on either side of the crankshaft 660, two superchargers 630 movably mounted on the exterior of the two slides 640, and a suspension 620 fixedly mounted on the superchargers 630. The top of the suspension 620 is movably mounted with a traction plate 680, an end post 6801 connected to the other end of the traction plate 680, and a thickened steel wire 6802 movably mounted on the end post 6801, with the other end of the thickened steel wire 6802 mounted on the end head 4102.

A positioning member 650 is movably mounted on the outer end of the crankshaft 660 , and the positioning member 650 is fixedly mounted on the movable sleeve 320 ; The two wire-binding wheels 530 are staggeredly distributed on the inner and outer sides of the thickened steel wire 6802 and are used to reset and calibrate the thickened steel wire 6802 after side bending.

[0025] By starting the second motor 6701, its internal transmission shaft will drive the crankshaft 660 to rotate regularly until the crankshaft 660 flips 180 degrees. The slide plate 640 pushed sideways by the crankshaft 660 will apply extrusion pressure to the supercharger 630 and the suspension 620. At this time, the suspension 620 will approach the sleeve 310, and the top of the suspension 620 will drive the traction plate 680, the end column 6801 and the thickened steel wire 6802 to stretch. Finally, the thickened steel wire 6802 will remain taut after being straightened and constrained by the two sets of positioning components 500, and the delivery sleeve 410 will bend sideways with the support column 4101 as the center. At this time, the welding wire 100 can effectively fit the part to be welded on the workpiece after passing through the anti-slip inner pad 330 and multiple clips 3301, thereby preventing the outer end of the welding wire 100 from being overly pressurized and slipping or loosening.

[0026] Example 2: Combine Figure 2 As shown, based on Example 1, the lifting assembly 200 includes a clamp 210 installed on the outside of the sleeve 310, a base 220 movably installed inside the clamp 210, a shaft 2201 inserted into the base 220, a cover 230 movably installed on the outside of the shaft 2201, and a locking stud 240 inserted into the cover 230 and fixed in the base 220.

[0029] Preferably, a plurality of guide gaskets 3101 distributed in a circumferential manner are used to reduce the frictional resistance during the delivery of the welding wire 100 , and the movable sleeve 320 is clamped in the annular groove on the inner wall of the sleeve 310 .

[0030] The movable sleeve 320 is clamped with a beam arm 340, a pad 3401 attached to the top of the beam arm 340, two first bolts 3402 inserted into the pad 3401 and fixed inside the movable sleeve 320, a column head 3403 movably installed at the other end of the beam arm 340, and a steering pad 3404 movably installed on the column head 3403.

[0031] Preferably, the length of the beam arm 340 is the same as that of the bellows 350 , and a plurality of steel wires distributed in a circumferential manner are provided inside the bellows 350 , and the outside of the bellows 350 is wrapped with a layer of heat-insulating tin foil.

[0032] A support column 4101 is fixedly mounted on the top of the delivery cannula 410 , and a steering pad 3404 is movably mounted on the support column 4101 ; The welding wire advancing mechanism 400 further includes a first chassis 440 fixedly mounted on the outside of the frame plate 4103, a first motor 4401 fixedly mounted inside the first chassis 440, a drive gear 4402 mounted on the first motor 4401, a screw sleeve 4105 fixedly mounted on the top of the frame plate 4103, a progressive stud 420 threadedly mounted in the screw sleeve 4105, and an outer frame 430 movably mounted on the outer wall of the progressive stud 420 and clamped to the outside of the frame plate 4103; An auxiliary wheel 460 is movably mounted on the inner side of the outer frame 430, and the auxiliary wheel 460 is located inside the frame plate 4103; A driving wheel 470 and a linkage gear 4701 fixedly mounted in the middle of the driving wheel 470 are movably mounted on the inner side of the frame plate 4103, and the driving gear 4402 is adapted to mesh with the linkage gear 4701; Two symmetrically distributed notches are provided on both sides of the wire-releasing sleeve 450, and heat-dissipating holes are provided in the heat-insulating sleeve 4502. Two second bolts 4501 are inserted into the interior of the wire-releasing sleeve 450, and the two second bolts 4501 are used to fix the heat-insulating sleeve 4502. The driving wheel 470 is composed of a main rod and two frustum-shaped guide wheels, and the linkage gear 4701 is located between the two frustum-shaped guide wheels; The auxiliary wheel 460 is composed of a secondary guide rod and an I-shaped wheel hub, and a rubber layer is fixedly mounted on the I-shaped wheel hub.

[0033] Preferably, the outer end of the thermal insulation sleeve 4502 is in an outwardly flared trumpet structure, and the inner wall of the thermal insulation sleeve 4502 is provided with a smooth coating. The wire release sleeve 450 is welded to the adapter 4104, and the thermal insulation sleeve 4502 is connected to the adapter 4104 and the inner cavity of the delivery sleeve 410. Specifically, by adjusting the progressive stud 420, the outer frame 430 will be pushed by the progressive stud 420 to rise and fall along the outside of the frame plate 4103, and finally the auxiliary wheel 460 will cooperate with the pushing wheel 470 to adjust the tightness of the passing welding wire 100. By changing the tightness of the welding wire 100 during delivery, the smoothness of the extended welding wire 100 and the part to be welded of the workpiece can be controlled, thereby avoiding the phenomenon of wire jumping due to excessive resistance between the outer end of the welding wire 100 and the part to be welded of the workpiece.

[0034] The working principle and usage process of the present invention are as follows: the locking stud 240 is reversed in advance until the locking stud 240 is pulled out from the interior of the base 220, and then the cover plate 230 is flipped sideways along the shaft 2201 as the center. Then, the base 220 and the cover plate 230 are wrapped around the pipe of the welding gun, and the reset cover plate 230 and the base 220 are fixed using the locking stud 240; Next, the tail end of the sleeve 310 is fixed inside the fixture 210, and the welding wire 100 is passed along the middle of the plurality of guide pads 3101 until the welding wire 100 passes through the anti-slip inner pad 330, the corrugated tube 350, the delivery sleeve 410, and the interior of the thermal insulation sleeve 4502, and finally passes through the thermal insulation sleeve 4502. When the worker holds the handle of the welding gun and controls the welding head of the welding gun toward the area to be welded on the workpiece, by starting the second motor 6701, as the second motor 6701 rotates forward or reverse 180 degrees, the two squeezed slides 640 will push the two sets of boosters 630 and the suspension 620 to move outward, and finally one of the compressed third bolts 520 will drive the traction plate 680, the end column 6801 and the thickened steel wire 6802 to extend toward the tail of the sleeve 310, and the delivery sleeve 410 clamped by the beam arm 340, the column head 3403 and the steering pad 3404 can be displaced and adjusted in angle along the left and right sides of the welding gun nozzle. As the side angle of the delivery sleeve 410 is adjusted, the bellows 350 will also bend accordingly. When the end of the welding wire 100 extends out of the heat-insulating sleeve 4502 and fits in the area of ​​the workpiece to be welded, the welding gun is controlled to move laterally along the outside of the workpiece. At this time, the first motor 4401 needs to be started and operated until the driving gear 4402 installed on the internal transmission shaft thereof helps the welding wire 100 to extend at a uniform speed. The welding wire 100 extending outward at a uniform speed can cooperate with the movement of the welding gun to accurately weld the workpiece. At the same time, the side bending part of the welding wire 100 after angle adjustment is clamped by multiple evenly distributed clamps 3301, thereby preventing the outer end of the welding wire 100 from moving back or loosening after being subjected to the reverse force of the workpiece, thereby avoiding abnormal welds caused by insufficient pressure between the welding wire and the workpiece.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
