Description

Technical Field

[0001] This invention relates to the field of welding torch wire feeding mechanism technology, specifically a welding torch wire feeding mechanism with freely adjustable angle. Background Technology

[0002] The wire feeding mechanism is mainly suitable for MIG / MAG welding operations. MIG / MAG welding machines require a nozzle-type welding torch and an extended nozzle to melt the welding wire delivered to the workpiece's top area. Carbon dioxide gas is used as the welding shielding gas. During welding, carbon dioxide gas is ejected from the welding torch nozzle, forming a protective layer that isolates the molten pool and arc from the adverse effects of oxygen, nitrogen, and other gases in the air, thereby obtaining a high-quality weld.

[0003] In actual operation, existing MIG / MAG welding machines mainly use two methods for feeding welding wire: manual feeding and drag-type wire feeder. Obviously, the first method is physically demanding and slow. In the second method, the drag-type wire feeder needs to be pre-loaded with a wire guide tube and welding torch. The drag-type welding machine continuously feeds the welding wire along the wire guide tube before it can work with the welding torch to assist welding operations on the workpiece. However, this method is too cumbersome and can cause some damage to the worker's wrists as working time increases. In addition, the connection between the wire guide tube and the drag-type wire feeder will occupy a certain amount of welding space.

[0004] In view of this, a welding torch wire feeding mechanism with freely adjustable angle was designed to solve the above problems. Summary of the Invention

[0022] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0023] 1. This invention fixes a hoisting assembly on the nozzle of a welding torch and installs a wire stabilization mechanism parallel to the nozzle within the hoisting assembly. It uses a lateral angle adjustment mechanism to control the lateral angle change of the wire delivery mechanism, so that the wire extending from the wire delivery mechanism can be effectively adjusted in angle. This provides an unobstructed path for the delivery of the wire at different angles according to the tilt state of the welding torch and the workpiece.

[0024] 2. The present invention uses an anti-slip inner pad fixedly installed at the outer end of the sleeve, and multiple clamps distributed in a circle fixedly installed on the inner wall of the anti-slip inner pad. When the welding wire feeding mechanism actively bends the welding wire, the front side of the welding wire bend will be clamped by multiple clamps, which prevents the outer end of the welding wire from slipping or loosening due to pressure from the workpiece direction, thereby ensuring the effectiveness of the weld.

[0025] 3. This invention movably installs the movable sleeve inside the sleeve, and controls the angle change of the welding wire delivery mechanism by rotating the movable sleeve. After the angle is adjusted, the welding wire delivery mechanism can bend laterally according to the direction of the welding gun nozzle. The angle between the welding wire delivery mechanism and the workpiece weld is adjusted after the lateral bending adjustment, until the welding wire extending through the welding wire delivery mechanism fits more smoothly with the workpiece weld, thereby avoiding obstruction of the welding wire's lateral movement.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0044] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0045] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a welding torch wire feeding mechanism with freely adjustable angles.

[0046] Example 1:

The hoisting assembly 200 is used to control the tilt angle between the welding wire stabilization mechanism 300 and the nozzle. The welding wire stabilization mechanism 300 is used to provide effective support for the lateral bending of the welding wire delivery mechanism 400. The welding wire delivery mechanism 400 is used to actively control the delivery speed and smoothness of the welding wire 100. The four sets of alignment assemblies 500 are used to enhance the stability of the lateral bending of the welding wire stabilization mechanism 300 and the welding wire delivery mechanism 400. The lateral angle adjustment mechanism 600 is used to control the lateral bending angle of the welding wire delivery mechanism 400.

[0048] The welding wire stabilization mechanism 300 includes a sleeve 310, a movable sleeve 320 movably installed inside the sleeve 310, and a corrugated pipe 350 fixedly installed at the other end of the movable sleeve 320.

[0049] The wire feeding mechanism 400 includes a delivery sleeve 410 fixedly installed at the other end of the corrugated pipe 350, a frame plate 4103 fixedly installed on the delivery sleeve 410, an adapter 4104 fixedly installed on the frame plate 4103, a wire feeding sleeve 450 fixedly installed at the other end of the adapter 4104, and a heat insulation sleeve 4502 inserted into the wire feeding sleeve 450. Two ends 4102 are fixedly installed on both sides of the delivery sleeve 410.

[0050] The alignment assembly 500 includes a bracket 510, two third bolts 520 inserted into the bracket 510, and two wire-bundling wheels 530 movably installed inside the bracket 510.

[0051] The lateral angle adjustment mechanism 600 includes a second housing 670 fixedly installed at the bottom of the movable sleeve 320, a second motor 6701 fixedly installed inside the second housing 670, a crankshaft 660 fixedly installed on the second motor 6701, two slide plates 640 disposed on both sides of the crankshaft 660, two booster components 630 movably installed outside the two slide plates 640, and a suspension 620 fixedly installed on the booster components 630.

[0052] A traction plate 680 is movably mounted on the top of the suspension 620, an end post 6801 is connected to the other end of the traction plate 680, and a thickened steel wire 6802 is movably mounted on the end post 6801. The other end of the thickened steel wire 6802 is mounted on the end head 4102. Two support legs 610 are fixedly mounted on the bottom of the movable sleeve 320. A cross rail 6101 is fixedly mounted on the bottom of the support legs 610. A first spring 6102 is provided in the inner groove of the cross rail 6101. A wing plate 6103 is fixedly mounted on the outer side of the other end of the cross rail 6101, and a second spring 6401 is connected between the wing plate 6103 and the slide plate 640. The bottom end of the suspension 620 is inserted into the inner groove of the cross rail 6101.

[0053] A positioning element 650 is movably mounted on the outer end of the crankshaft 660, and the positioning element 650 is fixedly mounted on the movable sleeve 320;

[0054] Two wire-bundling wheels 530 are staggered 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.

[0055] By starting the second motor 6701, its internal transmission shaft drives the crankshaft 660 to rotate regularly until the crankshaft 660 tilts to the side. The slide plate 640, which is pushed laterally by the crankshaft 660, applies pressure to the booster 630 and the suspension 620. At this time, the suspension 620 moves closer to the sleeve 310, and the top of the suspension 620 drives the traction plate 680, the end post 6801, and the thickened steel wire 6802 to extend. Finally, the thickened steel wire 6802 will remain taut after being straightened and constrained by the two sets of alignment components 500. The delivery sleeve 410 will bend laterally around the support post 4101. At this time, the welding wire 100 can effectively adhere to the part of the workpiece to be welded after passing through the anti-slip inner pad 330 and multiple clips 3301, thereby preventing the outer end of the welding wire 100 from slipping or loosening due to excessive pressure.

[0056] Example 2:

[0057] Combination Figure 2 As shown, based on Embodiment 1, the hoisting assembly 200 includes a clamp 210 installed outside the sleeve 310, a base 220 movably installed inside the clamp 210, a shaft 2201 inserted inside the base 220, a cover plate 230 movably installed outside the shaft 2201, and a locking stud 240 inserted inside the cover plate 230 and fixed inside the base 220.

[0058] Preferably, the groove on the top of the base 220 and the inner wall of the cover plate 230 are coated with a heat insulation coating, and the four end faces of the top of the clamp 210 are provided with symmetrically distributed limiting slots. The bottom of the base 220 is fixedly installed with a T-shaped column head, and the T-shaped column head is inserted into the inside of the clamp 210.

[0059] Furthermore, the outer wall of the T-shaped column head has a rough surface.

[0060] Example 3:

[0061] Combination Figure 3 , Figure 4 as well as Figure 9 As shown, in the above embodiment, the welding wire stabilization mechanism 300 also includes an anti-slip inner pad 330 fixedly installed inside the movable sleeve 320 and a plurality of clips 3301 fixedly installed on the inner wall of the anti-slip inner pad 330. A plurality of guide pads 3101 are fixedly installed on the tube wall at the tail end of the sleeve 310, and the outer end of the guide pad 3101 has an arc-shaped structure.

[0062] Preferably, a plurality of guide pads 3101 distributed in a circular pattern are used to reduce frictional resistance during the delivery of the welding wire 100, and the movable sleeve 320 is engaged in the annular groove on the inner wall of the sleeve 310.

[0063] The movable sleeve 320 is fitted 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.

[0064] Preferably, the length of the beam arm 340 is the same as the length of the corrugated pipe 350, and the corrugated pipe 350 has multiple steel wires arranged in a circular pattern inside, and the corrugated pipe 350 is wrapped with a heat-insulating tin foil layer on the outside.

[0065] A support column 4101 is fixedly installed on the top of the delivery sleeve 410, and a steering pad 3404 is movably installed on the support column 4101.

[0066] The wire feeding mechanism 400 also includes a first housing 440 fixedly installed outside the frame plate 4103, a first motor 4401 fixedly installed inside the first housing 440, a drive gear 4402 installed on the first motor 4401, a screw sleeve 4105 fixedly installed at the top of the frame plate 4103, a feed stud 420 threadedly installed in the screw sleeve 4105, and an outer frame 430 movably installed on the outer wall of the feed stud 420 and snapped onto the outside of the frame plate 4103.

[0067] 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;

[0068] A push wheel 470 and a linkage gear 4701 fixedly installed in the middle of the push wheel 470 are movably mounted on the inner side of the frame plate 4103, and the drive gear 4402 is adapted to mesh with the linkage gear 4701.

[0069] The wire feeding sleeve 450 has two symmetrically distributed slots on both sides, and the heat insulation sleeve 4502 has heat dissipation holes. Two second bolts 4501 are inserted into the inside of the wire feeding sleeve 450, and the two second bolts 4501 are used to fix the heat insulation sleeve 4502.

[0070] The drive wheel 470 consists of a main guide rod and two frustum-shaped guide wheels, and the linkage gear 4701 is located between the two frustum-shaped guide wheels;

[0071] The auxiliary wheel 460 consists of a secondary guide rod and an I-shaped hub, with a rubber layer fixedly installed on the I-shaped hub.

[0072] Preferably, the outer end of the heat insulation sleeve 4502 has an outwardly flared horn structure, and the inner wall of the heat insulation sleeve 4502 is provided with a smooth coating. The wire feeding sleeve 450 is welded to the adapter 4104, and the heat insulation sleeve 4502 is connected to the adapter 4104 and the inner cavity of the delivery sleeve 410.

[0073] Specifically, by adjusting the advance stud 420, the outer frame 430 is pushed up and down along the outside of the frame plate 4103 by the advance stud 420. Finally, the auxiliary wheel 460 will cooperate with the push wheel 470 to adjust the tension of the passing welding wire 100. By changing the tension of the welding wire 100 during delivery, the smoothness between the extended welding wire 100 and the part of the workpiece to be welded can be controlled, avoiding excessive resistance between the outer end of the welding wire 100 and the part of the workpiece to be welded, thus preventing wire skipping.

[0074] The working principle and usage process of this invention are as follows: First, reverse the locking stud 240 until the locking stud 240 is pulled out from the inside of the base 220. Then, flip the cover plate 230 along the shaft 2201 as the center. Then, wrap the base 220 and the cover plate 230 around the pipe of the welding gun and use the locking stud 240 to fix the reset cover plate 230 and the base 220.

[0075] Next, the end of the sleeve 310 is fixed inside the clamp 210, and then the welding wire 100 is inserted along the middle of the multiple guide pads 3101 until the welding wire 100 passes through the inside of the anti-slip inner pad 330, the bellows 350, the delivery sleeve 410 and the heat insulation sleeve 4502 in sequence, and finally comes out from the heat insulation sleeve 4502.

[0076] When the worker holds the handle of the welding torch and controls the welding head of the torch to be welded towards the workpiece area, the second motor 6701 is started. As the second motor 6701 rotates forward or backward 180 degrees, the two compressed sliding plates 640 will exert a thrust on the two sets of pressure boosters 630 and the suspension 620 to move outward laterally. Finally, one of the compressed third bolts 520 will drive the traction plate 680, end column 6801 and thickened steel wire 6802 to extend towards the tail of the sleeve 310. The delivery sleeve 410, which is clamped by the beam arm 340, column head 3403 and steering pad 3404, can then be displaced and its angle adjusted along the left and right sides of the welding torch nozzle. As the lateral angle of the delivery sleeve 410 is adjusted, the corrugated pipe 350 will also bend accordingly.

[0077] When the end of the welding wire 100 extends out of the heat insulation sleeve 4502 and fits into 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 to run until the drive gear 4402 installed on its internal transmission shaft 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 assist welding on the workpiece.

[0078] At the same time, the angle-adjusted welding wire 100 is clamped by multiple evenly distributed clamps 3301 at its side bend, thereby preventing the welding wire 100 from regressing or loosening after being subjected to the reverse force of the workpiece at its outer end. This can prevent the welding wire from being under insufficient pressure with the workpiece, which could lead to abnormal weld seams.

[0079] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
