Description

Technical Field

[0001] This utility model relates to the field of composite welding gun technology, and in particular to a composite welding gun positioning device with welding wire guide. Background Technology

[0002] Laser-arc hybrid welding technology is a novel multi-source composite welding process that combines the advantages of traditional arc welding and laser welding. By synergistically using two heat sources with different physical properties—light and electricity—during the welding process, this technology fully leverages the coupling effect between the heat sources, thereby significantly improving molten pool stability, optimizing weld width-to-depth ratio, increasing welding speed, and enhancing weld quality, demonstrating excellent process adaptability. This technology has broad application prospects in high-end equipment manufacturing fields such as automotive manufacturing, shipbuilding, and aerospace, and is particularly suitable for welding medium-thick plates of aluminum alloys, copper alloys, stainless steel, and other emerging composite materials.

[0003] While the above-mentioned technologies achieve welding of objects, the lack of dual constraints and elastic adaptive structure in the feeding of welding wire leads to radial deviation of the welding wire, resulting in insufficient positioning accuracy and affecting welding quality and device versatility. Therefore, a composite welding gun positioning device with welding wire guide is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a composite welding gun positioning device with welding wire guide, which aims to solve the problem that the lack of dual constraints and elastic adaptive structure in the welding wire feeding of the prior art leads to radial displacement of the welding wire, resulting in insufficient positioning accuracy and thus affecting welding quality and device versatility.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a composite welding gun positioning device with welding wire guide, comprising a handheld component, a beam control component, a focusing transmission sleeve, and an arc welding gun sleeve, wherein the outer wall of the focusing transmission sleeve is provided with a sleeve, the inside of the sleeve is provided with a welding wire size adaptation component, and the inside of the sleeve is provided with a welding wire positioning guide component. The welding wire positioning and guiding assembly includes a guide roller, a sliding ball slidably connected to the outer wall of the guide roller, a groove opened on the inner wall of the sleeve, and a copper nozzle fixedly connected to the outer wall of the sleeve.

[0006] As a further description of the above technical solution: The outer wall of the guide roller is fixedly connected to the inside of the groove.

[0007] As a further description of the above technical solution: The outer wall of the sliding ball is slidably connected to the inside of the groove.

[0009] As a further description of the above technical solution: The welding wire size adaptation component includes a ring, the inner wall of which has a slot, and an arc-shaped limiting block is elastically connected inside the slot by a spring.

[0010] As a further description of the above technical solution: The outer wall of the ring is fixedly connected to the outer wall of the sliding ball.

[0011] As a further description of the above technical solution: One end of the spring is fixedly connected to the outer wall of the arc-shaped limiting block, and the other end of the spring is fixedly connected to the inside of the slot.

Multiple sets of arc-shaped limiting blocks are provided, and the multiple sets of arc-shaped limiting blocks are distributed in a ring along the central axis of the ring.

[0013] This utility model has the following beneficial effects: 1.

Combined with the precise guidance of the copper nozzle, the welding wire is accurately positioned, ensuring conveying stability and improving welding quality.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 This utility model provides an embodiment of a composite welding gun positioning device with welding wire guide, including a handheld component 1. The bottom of the handheld component 1 is specifically provided with a laser fiber optic connection port, an arc water pipe connection port, a protective gas connection port, a cooling water pipe connection port, and a switch control wiring. An integrated start switch is provided on the inner side of the handheld component 1. A beam control component 2 is provided with an optical reflector for changing the laser propagation direction, a driving component for driving the optical reflector to move, and an optical lens assembly for focusing and protecting the laser. A focusing transmission sleeve 3 is connected to the beam control component 2 and is used to guide the laser to the workpiece and adjust the laser action position parameters. An arc welding gun sleeve 4 is provided with electrodes, gas flow protection components, pipeline interfaces, and cooling structures required for arc welding. A sleeve 6 is provided on the outer wall of the focusing transmission sleeve 3. A welding wire size adaptation component 7 and a welding wire positioning guide component 5 are provided inside the sleeve 6. The welding wire positioning and guiding assembly 5 includes a guide roller 51. The outer wall of the guide roller 51 is slidably connected to a sliding ball 52 made of wear-resistant alloy steel with a polished surface to reduce the coefficient of friction. The inner wall of the sleeve 6 has a groove 53 for limiting the installation of the guide roller 51. The outer wall of the sleeve 6 is fixedly connected to a copper nozzle 54 for guiding the welding wire to output accurately and preventing the end of the welding wire from deviating. The outer wall of the guide roller 51 is fixedly connected inside the groove 53, and the outer wall of the sliding ball 52 is slidably connected inside the groove 53. Subsequently, the centered welding wire enters the precise positioning stage formed by the welding wire positioning and guiding assembly 5. The welding wire contacts multiple sets of sliding balls 52 distributed in a ring along the central axis of the sleeve 6. These sliding balls 52 slide within the groove 53, converting the sliding friction of the welding wire into rolling friction, significantly reducing the conveying resistance. Simultaneously, the guide roller 51 further constrains the trajectory of the welding wire. Finally, the welding wire is stably guided to the copper nozzle 54 fixed to the outer wall of the sleeve 6 and accurately delivered.

[0019] Reference Figures 2-4 Multiple sets of sliding balls 52 are provided, and these sets of sliding balls 52 are distributed in a ring along the central axis of the sleeve 6. The welding wire size adaptation component 7 includes a ring 71 made of high-strength engineering plastic with a certain structural rigidity. The inner wall of the ring 71 has a slot 72. Inside the slot 72, an arc-shaped limiting block 74 is elastically connected by a spring 73 made of stainless steel with a preset elastic deformation range. The inner wall of the arc-shaped limiting block 74 is made of flexible wear-resistant material and fits against the outer surface of the welding wire. The outer wall of the ring 71 is fixed. Connected to the outer wall of the sliding ball 52, one end of the spring 73 is fixedly connected to the outer wall of the arc-shaped limiting block 74, and the other end of the spring 73 is fixedly connected to the inside of the slot 72. The outer wall of the arc-shaped limiting block 74 is clearance-fitted with the inner wall of the slot 72 and can slide radially along the inside of the slot 72. Multiple sets of arc-shaped limiting blocks 74 are provided, and the multiple sets of arc-shaped limiting blocks 74 are distributed in a ring along the central axis of the ring 71. During the welding process, the welding wire first enters the adjustment channel formed by the welding wire size adaptation component 7. Under the elastic action of the spring 73, the multiple sets of arc-shaped limiting blocks 74 in this component can radially extend and retract within the slot 72, thereby adaptively conforming to welding wires of different diameters, achieving initial centering of the welding wire, and preventing radial displacement.

[0020] Working Principle: During use, in the welding process, the welding wire first enters the adjustment channel composed of the welding wire size adaptation component 7. Multiple sets of arc-shaped limiting blocks 74 in this component, under the elastic action of springs 73, can radially extend and retract within the slots 72, thereby adaptively conforming to welding wires of different diameters, achieving initial centering of the welding wire and preventing radial deviation. Subsequently, the centered welding wire enters the precision positioning stage composed of the welding wire positioning and guiding component 5. The welding wire contacts multiple sets of sliding balls 52 distributed annularly along the central axis of the sleeve 6. These sliding balls 52 slide within the grooves 53, converting the sliding friction of the welding wire into rolling friction, significantly reducing the conveying resistance. Simultaneously, the guide rollers 51 further constrain the trajectory of the welding wire. Finally, the welding wire is stably guided to the copper nozzle 54 fixed to the outer wall of the sleeve 6 and precisely delivered.
