Description

Technical Field

[0001] This invention relates to the field of ring-shaped component welding technology, and more specifically to a ring-shaped component welding device. Background Technology

[0002] Ring-shaped components, such as flanges, bearing races, and pipe fittings, are key basic parts in mechanical equipment and pipeline systems. The quality of their butt welds directly determines the load-bearing capacity, sealing performance, and service life of the entire component.

[0003] Currently, automated welding of such parts mostly employs a workpiece rotation and welding torch fixation method, forming a single straight circumferential weld. This weld exhibits significant stress concentration, easily becoming a weak point in the structure. To improve quality, existing technologies have introduced various processes such as welding torch oscillation, wire straightening, and post-weld treatment. However, these functions are often implemented by separate equipment or complex electrical control systems, resulting in poor coordination between processes, unreal-time wire straightening, and delayed post-weld treatment. This leads to unstable welding quality, low equipment integration, and difficulty in further improving efficiency.

[0004] To address this, we designed a ring-shaped welding device. Summary of the Invention

A one-way bearing, which is fixedly connected to the rotating rod; A conveyor wheel, which is fixedly connected to the outer ring portion of the one-way bearing; A disc cam is fixedly connected to the side wall of the rotating rod.

[0011] Preferably, the conveying mechanism further includes: A circular shaft, which is symmetrically rotated and connected to the side wall of the mating plate; A lever fixed to the side wall of a round shaft, wherein sliding shaft one and sliding shaft two are fixed to the side walls at both ends of the lever, respectively; The sliding shaft and the cam groove portion of the disc cam are slidably connected; A conveyor plate, wherein push plates are symmetrically fixed to the side walls of the conveyor plate, and rectangular holes are provided on the push plates.

[0014] Preferably, the L-shaped telescopic assembly includes: A long, rectangular box, which is fixedly connected to the connecting seat; The L-shaped rod is slidably connected to the inner wall of the long box. The return spring has its two ends fixedly connected to the inner wall of the long strip box and the L-shaped rod, respectively. The grinding disc and the two L-shaped rods are fixedly connected.

[0015] Compared with existing technologies, the advantages of this invention are: 1. This invention indirectly drives a gear and main shaft to perform stable fan-shaped oscillations of the welding torch by setting up a drive motor, crossbar, bearing shaft, and rectangular frame. Simultaneously, the clamping assembly drives the annular component to rotate at a uniform speed. The combined motion of the welding torch oscillation and the workpiece rotation naturally forms a continuous and uniform wavy weld seam. Compared to traditional straight weld seams, this wavy weld seam effectively disperses load stress and reduces stress concentration, thereby significantly improving the fatigue strength, toughness, and overall reliability of the welded joint. This process is entirely driven by a mechanical structure, eliminating the need for expensive CNC systems, thus reducing costs while ensuring high performance. 2. During the aforementioned oscillating welding process, the contact between rack two and the fixed trigger plate triggers the intermittent unidirectional rotation of gear two and the rotating rod. This rotation drives the conveyor wheel to complete quantitative wire feeding via a one-way bearing; simultaneously, it drives the disc cam to rotate. The disc cam drives two conveyor plates made of elastic plates to reciprocate in opposite directions via a lever mechanism. The elastic conveyor plates ensure that the welding wire is always subjected to a flexible rolling straightening force during the conveying process, effectively eliminating the original bending of the welding wire, ensuring that the welding wire entering the molten pool is straight, and improving the wire feeding stability and arc stability. At the same time, clean gas is pulsedly sprayed onto the newly formed weld for accelerated cooling, comprehensively improving the hardness, toughness, and internal quality of the weld.

[0016] 3. The grinding disc mounted on the L-shaped rod, under the elastic pressure provided by the return spring, always remains in contact with the surface of the weld reinforcement layer. Because the movement trajectory of the grinding disc is strictly synchronized with the oscillation trajectory of the welding torch, the grinding operation can closely follow the movement of the weld pool, achieving real-time, online finishing of the weld. This eliminates the need for a separate subsequent grinding process, shortens the production cycle, and improves overall operational efficiency. Attached Figure Description

The main shaft 51 can only rotate and will not produce vertical displacement. The welding gun 59 is fixed to the bottom wall of the spindle 51 by the mounting plate 58; Gear 53 is fixedly connected to the side wall of main shaft 51; Rack 54 is slidably connected to the top wall of the U-shaped frame 52, and rack 54 is meshed with gear 53; The drive motor 510 is fixed to the bottom wall of the welding seat 3, and a crossbar 511 is fixed to the output end of the drive motor 510. A bearing shaft 512 is fixed to the bottom wall of one end of the crossbar 511, and a rectangular frame 513 is fixed to the top wall of the rack 54. The bearing shaft 512 and the inner side wall of the rectangular frame 513 slide against each other.

[0024] Executive agency 5 also includes: A connecting seat 55 is fixed to the bottom wall of the rack 54, and a through hole is provided on the top wall of the U-shaped frame 52 for the connecting seat 55 to move. L-shaped telescopic component 56 is symmetrically fixed to the bottom wall of connecting seat 55; L-shaped telescopic assembly 56 includes: Long box 561 (combined) Figure 3 and Figure 4 As shown in the figure, it is fixedly connected to the connecting seat 55; L-shaped rod 563, which is slidably connected to the inner wall of long box 561; The return spring 562 has its two ends fixedly connected to the inner wall of the long strip box 561 and the L-shaped rod 563, respectively. The grinding disc 57 is fixedly connected to the L-shaped rod 563 in the two L-shaped telescopic assemblies 56.

[0025] Conveying mechanism 6 includes: The mating plate 61 fixed to the mounting plate 58 (connected) Figure 4 and Figure 5 As shown), the plate 61 is tilted. A conveying pipe 62 is fixedly connected to a welding torch 59; a welding wire is installed through the conveying pipe 62. Rotating rod 63 is symmetrically and rotatably connected to the inner wall of mating plate 61; One-way bearing 64 is fixedly connected to rotor 63; one-way bearing 64, also known as overrunning clutch, is a type of bearing whose core feature is that it allows free rotation in one direction while locking in the opposite direction. This bearing achieves one-way limiting through the cooperation of rollers, needle rollers, or balls within a metal housing with specially shaped rolling seats.

[0026] The conveyor wheel 66 has an annular groove on its side wall for the wire harness to pass through, and is fixedly connected to the outer ring of the one-way bearing 64. The surfaces of the two conveyor wheels 66 are made of a material with a high coefficient of friction (or both are fitted with meshing toothed rings). When one of the conveyor wheels 66 moves the welding wire downward, it can drive the other conveyor wheel 66 to rotate synchronously. During the passive rotation of the conveyor wheel 66, it will drive the outer ring of the one-way bearing 64 fixed to it to rotate. At this time, the outer ring of the one-way bearing 64 will not drive its inner ring to rotate synchronously.

[0027] The disc cam 65 is fixedly connected to the side wall of the rotating rod 63.

[0028] Conveying mechanism 6 also includes: A circular shaft 67 is symmetrically rotatably connected to the side wall of the mating plate 61; A lever 68 is fixed to the side wall of the round shaft 67. A sliding shaft 69 and a sliding shaft 610 are fixed to the side walls of the two ends of the lever 68, respectively. A rectangular hole 614 is opened on the push plate 613. The sliding shaft 610 slides after abutting against the inner wall of the adjacent rectangular hole 614. When the rotating rod 63 rotates, the rotating rod 63 drives the disc cam 65 to rotate synchronously through the outer ring of the one-way bearing 64.

[0029] The slide shaft 69 and the cam groove of the disc cam 65 are slidably connected; The conveyor plate 611 is made of an elastic plate. Push plates 613 are symmetrically fixed to the side wall of the conveyor plate 611. During the rotation of the disc cam 65, the lever 68 will rotate in both directions around the axis 67 via the sliding shaft 69. The other end of the lever 68 will drive the push plate 613 to reciprocate through the sliding shaft 610. Through the design of the cam groove profile of the disc cam 65 and the installation position of the disc cam 65 and the conveyor wheel 66 on the one-way bearing 64, during each conveying of the welding wire by the conveyor wheel 66, firstly, the two push plates 613 drive the corresponding conveyor plate 611 to abut and squeeze against the side wall of the welding wire, so that the conveyor wheel 66 straightens this part of the welding wire. Then, the push plate 613 drives the corresponding conveyor plate 611 away, so that the welding wire can be conveyed downward quickly.

[0030] A guide 13 is fixedly connected to the conveyor plate 611.

[0031] The enhancement mechanism 7 includes: A box 71 is symmetrically fixed to the mating plate 61; The inside of the box 71 is sealed and slidably connected to a piston 72, and the push plate 613 is fixedly connected to the adjacent piston 72. The first one-way tube 73 and the second one-way tube 74 are fixedly connected. The first one-way tube 73 is fixedly connected to the external clean air source storage device and is also fixedly connected to the box body 71. The push plate 613 drives the piston 72 fixed to it to slide back and forth in the corresponding box body 71 in a sealed manner. Then, the external clean air source is drawn into the box body 71 through the first one-way tube 73, and then the clean air source is squeezed to the jet head 75 through the second one-way tube 74 to form a high-speed airflow.

[0032] The jet head 75 is fixedly connected to the welding torch 59, and the second one-way tube 74 and the jet head 75 are fixedly connected.

[0033] Gear 2 81 is fixedly connected to the side wall of the rotating rod 63 (connected) Figure 6 and Figure 7 As shown), vertical plates 83 are symmetrically fixed to the side wall of the mating plate 61. Each vertical plate 83 has a rack 84 slidably connected through its side wall. A torsion spring 82 is sleeved and fixed to the side wall of the rotating rod 63. The torsion spring 82 is fixed to the side wall of the mating plate 61. The rack 84 is meshed with the adjacent gear 81. Trigger plates 10 are symmetrically fixed to the bottom wall of the U-shaped frame 52. Each rack 84 is in contact with the adjacent trigger plate 10.

[0034] In this invention, the operator places two annular parts to be welded next to two clamping assemblies 24. After being clamped and fixed by electric grippers, their positions in the horizontal and vertical directions are adjusted by a sliding module, and they are rotated by a rotary motor, thereby adjusting the joint of the annular parts to a suitable welding position.

[0035] The drive motor 510 is started, and its output end drives the crossbar 511 to rotate. The bearing shaft 512, which is fixed to the end of the crossbar 511, moves accordingly. As the bearing shaft 512 slides against the inner wall of the rectangular frame 513 fixed to the top of the rack 54, the circular motion of the bearing shaft 512 is converted into the reciprocating linear motion of the rectangular frame 513 and the rack 54 in the horizontal direction.

[0036] The rack 54 drives the gear 53 it meshes with to perform alternating forward and reverse rotational motion. The gear 53 drives the main shaft 51 and the welding torch 59 and the delivery pipe 62, which are fixed to its bottom by the mounting plate 58, to perform a fan-shaped reciprocating oscillation around the axis of the main shaft 51 at a specific angle.

[0037] Meanwhile, the rotary motor in the clamping assembly 24 drives the clamped annular part to rotate at a uniform speed. Therefore, a relative composite motion is generated between the fan-shaped oscillating welding torch 59 and the uniformly rotating annular joint, resulting in a continuous and uniform wavy weld at the joint of the annular part. Compared to a straight weld, this weld trajectory effectively disperses stress and improves the mechanical properties and reliability of the welded joint.

[0038] As the mounting plate 58 drives the mating plate 61 to reciprocate with the main shaft 51, the two symmetrically arranged racks 84 will successively abut against and press against the trigger plate 10 fixed to the bottom wall of the U-shaped frame 52. When the welding torch swings to one side, the corresponding rack 84 abuts against and presses against the adjacent trigger plate 10, and the rack 84 is forced to slide within the vertical plate 83, driving the gear 81 meshing with it to rotate by a set angle.

[0039] At this time, gear 2 81 drives the inner ring of the fixed rotating rod 63 and one-way bearing 64 to rotate. Under the action of one-way bearing 64, this rotation is effectively transmitted to the conveying wheel 66, driving it to rotate and conveying the welding wire in close contact with it downwards for a predetermined length, i.e., one wire feeding step. The conveying wheel 66 on the other side rotates as a driven clamping wheel to ensure stable wire feeding. The function of torsion spring 82 is that when rack 2 84 moves to the end of its stroke, its rack part will disengage from the corresponding gear 2 81, at which time it can reset gear 2 81 and rack 2 84 to the initial position, ready for the next trigger.

[0040] Simultaneously, the rotational motion of the rotating rod 63 also drives the rotating disc cam 65, which is fixed to it, to rotate. The cam groove of the disc cam 65 drives the lever 68 to swing around the circular shaft 67 via the sliding shaft 69. The sliding shaft 610 at the other end of the lever 68 moves accordingly and slides in the rectangular hole 614 of the push plate 613, thereby driving the two push plates 613 and the conveyor plate 611 fixed to them to move towards or away from each other.

[0041] By controlling the movement sequence of the pusher plate 613 through the contour design of the disc cam 65, within one wire feeding cycle, the two conveyor plates 611 first move towards each other under the guidance of the guide member 13, clamping and straightening the welding wire segment to be conveyed; then, the conveyor plates 611 release and reset, and then the conveyor wheel 66 performs the above wire feeding action, smoothly pushing the straightened welding wire to the welding torch 59. This forms a linkage mechanism of straightening first and then conveying, ensuring that the welding wire always enters the molten pool in a straight state, greatly improving the wire feeding stability and welding quality.

[0042] Furthermore, the reciprocating motion of the pusher plate 613 directly drives the piston 72, which is fixed to it, to slide in a sealed manner within the housing 71. The movement of the piston 72 constitutes a piston pump: when it moves to one side, it draws in clean gas from the outside through the first one-way pipe 73; when it moves to the other side, it delivers compressed gas to the jet head 75 through the second one-way pipe 74. The jet head 75 precisely sprays this intermittent high-speed airflow onto the newly formed, still high-temperature wavy weld surface. This intermittent forced cooling, synchronized with the wire feeding cycle, can accelerate the cooling of specific areas of the weld metal, refine the grains, and thus improve the hardness and toughness of the weld.

[0043] Furthermore, the horizontally reciprocating rack 54 drives the two L-shaped telescopic components 56 and the grinding disc 57 to move synchronously via the connecting seat 55. The return spring 562 in the L-shaped telescopic component 56 provides elastic pressure to the grinding disc 57, enabling it to always adaptively conform to and grind the excess height of the weld. This grinding action is completely synchronized with and follows the swing of the welding torch 59, allowing for post-weld finishing of the weld, reducing stress concentration, and further improving the fatigue strength of the welded structure.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
