Description

Technical Field

[0001] This utility model relates to the field of automated welding technology, specifically a high-precision aluminum alloy welding wire feeding intelligent feedback adjustment mechanical structure. Background Technology

[0002] With the increasing demands for welding quality in the industrial manufacturing sector, aluminum alloy welding technology, as a key process, requires exceptional stability and precision. Smooth wire feeding is fundamental to ensuring welding quality during aluminum alloy welding; however, existing wire feeding mechanisms often exhibit significant shortcomings when dealing with abnormal situations such as wire jamming.

[0003] Traditional welding wire feeding systems lack an effective and immediate feedback adjustment mechanism when encountering wire jamming. Once the wire becomes stuck between the two pressure rollers, the system cannot respond quickly, resulting in continuous and improper pressure on the wire. This not only increases the risk of wire breakage but may also damage the wire feeding mechanism, thus affecting the continuity and stability of the entire welding process. Furthermore, traditional systems cannot dynamically adjust the wire feeding speed when faced with wire jamming. This inflexible control strategy not only reduces wire feeding efficiency but may also cause excessive stretching of the wire at the obstruction point, further exacerbating the instability of welding quality. More importantly, the traditional wire feeding mechanism lacks an intelligent feedback mechanism and cannot adaptively adjust according to the real-time status of the wire. At the moment of wire jamming, the system cannot automatically adjust the pressure rollers. The lack of intelligent feedback not only limits the automation level of welding equipment but also increases the need for manual intervention, reducing production efficiency and welding quality consistency. Therefore, it is crucial to develop a high-precision aluminum alloy welding wire feeding mechanism with intelligent feedback adjustment function. This mechanism should be able to automatically trigger the adjustment mechanism when abnormalities such as wire jamming are detected, adjusting the spacing of the pressure rollers and the wire feeding speed to ensure smooth wire feeding, thereby improving the stability and reliability of the welding process, optimizing wire feeding efficiency, reducing wire loss, and ultimately improving overall welding quality and production efficiency. To this end, we propose a high-precision aluminum alloy welding wire feeding intelligent feedback adjustment mechanism to solve the above problems. Utility Model Content

Detailed Implementation

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved intelligent feedback adjustment mechanical structure for wire feeding in aluminum alloy welding. The technical solution of this utility model is as follows:

[0024] like Figure 1 - Figure 5 As shown, a high-precision aluminum alloy welding wire feeding intelligent feedback adjustment mechanical structure includes a housing 1, a side plate 2 fixedly connected to the side wall of the housing 1, a wire feeding device, a feedback adjustment device, and a drive device disposed inside the housing 1, the wire feeding device including a wire inlet 3, the wire inlet 3 fixed to the right side of the housing 1, the left end of the wire inlet 3 penetrating through the side wall of the housing 1 and extending into the interior of the housing 1, a wire guide tube 6 disposed inside the housing 1, a fixing frame 7 fixedly connected to the surface of the wire guide tube 6, the fixing frame 7 being fixedly connected to the inner wall of the housing 1, and the left end of the housing 1... A wire outlet nozzle 10 is fixedly connected to the side. The right end of the wire outlet nozzle 10 penetrates the side wall of the housing 1 and extends into the interior of the housing 1. The feedback adjustment device includes a fixing block 11, which is fixed to the inner wall of the housing 1. The drive device includes a motor 22, which is fixed to the upper surface of the side plate 2. The output end of the motor 22 is fixedly connected to a drive shaft 23. The end of the drive shaft 23 away from the motor 22 penetrates the side wall of the housing 1 and extends into the interior of the housing 1. The end of the drive shaft 23 away from the motor 22 is fixedly connected to a drive disk 31.

[0025] Furthermore, the wire feeding device also includes two symmetrically arranged wire feeding shafts 4. The lower wire feeding shaft 4 is fixedly connected to the inner wall of the outer casing 1, and the upper wire feeding shaft 4 is slidably connected to the inner wall of the outer casing 1. The upper wire feeding shaft 4 is also slidably connected to the inner wall of the fixing block 11. Each wire feeding shaft 4 has a pressure roller 5 rotatably connected to its surface. The inner wall of the outer casing 1 is rotatably connected to two symmetrically arranged rotating shafts 8. Each rotating shaft 8 has a wire feeding roller 9 fixedly connected to its surface. Because the upper wire feeding shaft 4 is slidably connected to the inner wall of the outer casing 1, when the pressure roller 5 moves upward, the pressure roller 5 can drive the corresponding wire feeding shaft 4 to move along the inner wall of the fixing block 11 on the inner wall of the outer casing 1.

[0026] Furthermore, the feedback adjustment device also includes a spring 12, the lower end of which is fixedly connected to the surface of the upper wire feeding shaft 4, and the upper end of which is fixedly connected to the inner wall of the fixed block 11. A moving rod 13 is fixedly connected to the surface of the wire feeding shaft 4, and a lever 14 is rotatably connected to the side wall of the moving rod 13. A support shaft 15 is fixedly connected to the inner wall of the outer casing 1, and the front end of the support shaft 15 passes through the side wall of the lever 14 and extends to the front of the lever 14. A second rotating shaft 16 is rotatably connected to the inner wall of the outer casing 1, and a turntable 17 is fixedly connected to the surface of the second rotating shaft 16. A groove 18 is provided at the front end of the turntable 17. A connecting rod 19 is rotatably connected to the side wall of the lever 14. A circular slider 20 is rotatably connected to the inner wall of the lower half of the connecting rod 19. Two symmetrically arranged limiting cylinders 21 are fixedly connected to the surface of the circular slider 20. The lower end of the circular slider 20 is slidably connected to the inner wall of the slide groove 18. Each limiting cylinder 21 is slidably connected to the inner wall of the slide groove 18. The support shaft 15 serves as the fulcrum of the lever 14. The support shaft 15 is close to the turntable 17 and far from the moving rod 13. Therefore, when the connection end of the lever 14 and the moving rod 13 is subjected to a little upward force, the connection end of the lever 14 and the turntable 17 can be easily moved. Through the cooperation of the slide groove 18 and the limiting cylinders 21, the circular slider 20 can only move along the trajectory of the slide groove 18.

[0027] Furthermore, the drive device also includes a drive rod 24, which is rotatably connected to the rear end of the drive disc 31. A gear 25 is fixedly connected to the front end of each wire feeding roller 9. The front end of the lower rotating shaft 1 8 penetrates the inner wall of the corresponding gear 25 and extends to the front of the gear 25. A pulley 26 is fixedly connected to the surface of the lower rotating shaft 1 8, and a pulley 27 is fixedly connected to the surface of the rotating shaft 2 16. The same belt 28 is fitted onto the surfaces of pulley 1 26 and pulley 27. By configuring the drive disc 31 and the drive rod 24... When the drive disk 31 rotates, it drives the drive rod 24 to rotate around the drive shaft 23. The other end of the drive rod 24 is connected to the turntable 17, so the kinetic energy of the drive disk 31 is transmitted to the turntable 17 through the drive rod 24. The drive rod 24 pushes the turntable 17 to rotate through the circular slider 20. The rotation speed of the turntable 17 is different depending on the distance between the circular slider 20 and the rotation shaft 16. When the circular slider 20 is closer to the rotation shaft 16, the rotation speed of the turntable 17 is greater. When the circular slider 20 is farther from the rotation shaft 16, the rotation speed of the turntable 17 is smaller.

[0028] Furthermore, each wire pressing roller 5 has a wire groove 29 on its surface, and each wire feeding roller 9 has a wire groove 30 on its surface. The wire inlet 3, wire guide tube 6, and wire outlet 10 are on the same horizontal line and are on the same horizontal line as the center line of the wire groove 29 and the wire groove 30. By setting the wire groove 29 and the wire groove 30, the welding wire can be put into the wire groove 29 and the wire groove 30, which can prevent the welding wire from deviating during movement.

[0029] Furthermore, the drive rod 24 is rotatably connected to the upper half surface of the circular slider 20, and the upper end of the drive rod 24 is rotatably connected to the lower surface of the connecting rod 19. This arrangement allows the drive rod 24 to be positioned between the limiting cylinder 21 and the connecting rod 19, and also to be fitted onto the surface of the circular slider 20. This arrangement does not affect the movement of the circular slider 20 within the slide groove 18, and also allows the kinetic energy of the rotation of the drive disk 31 to be smoothly transmitted to the turntable 17 via the drive rod 24.

[0030] Working principle: During use, the welding wire enters through the wire inlet 3, passes between the two wire pressure rollers 5, along the first welding wire groove 29, then through the wire guide tube 6, passes between the two wire feeding rollers 9, along the second welding wire groove 30, and finally exits through the wire outlet 10. The motor 22 is turned on, driving the drive shaft 23 to rotate. The drive shaft 23 drives the drive disc 31 to rotate, which in turn drives one end of the drive rod 24 to rotate. This causes the other end of the drive rod 24 to drive the turntable 17 to rotate, which in turn drives the second rotating shaft 16 to rotate. The second rotating shaft 16 is connected to a belt... Wheel 26, pulley 27, and belt 28 drive shaft 8 to rotate. The rotating shaft 8 drives gear 25, which is fixedly connected to it, to rotate. Gear 25, through meshing, drives another gear 25 to rotate. The two gears 25 drive the two wire feeding rollers 9 to rotate in opposite directions, causing the welding wire to move smoothly from the wire inlet 3 to the wire outlet 10. During this movement, the wire may get stuck between the two pressure rollers 5, preventing it from passing smoothly. However, the gears 25 drive the wire feeding... Roller 9 continues to drive the welding wire, causing the area where the wire is stuck to exert pressure on the two pressure rollers 5. The upper pressure roller 5 is pressed, causing the wire feeding shaft 4 to move upward. The spring 12 contracts, and at the same time, the wire feeding shaft 4 drives the moving rod 13 to move upward. Through the lever principle, the other end of the lever 14 moves downward, causing the connecting rod 19 to drive the circular slider 20 and the driving rod 24 to move along the trajectory of the groove 18. This causes the diameter of the end of the driving rod 24 that contacts the circular slider 20 to increase when rotating around the rotating shaft 16, thereby increasing the diameter of the turntable. The rotational speed of 17 decreases, and the distance between the two pressure rollers 5 increases due to wire jamming, allowing the jammed wire to pass smoothly between the two pressure rollers 5, enter the guide tube 6, and then enter the wire outlet 10 from the outlet of the guide tube 6, and exit from the outlet of the wire outlet 10 for use. After the jammed part passes smoothly through the two pressure rollers 5, the upper pressure roller 5 drives the wire feeding shaft 4 to reset due to the elastic force of the spring 12. Similarly, the connecting rod 19 drives the circular slider 20 and the limiting cylinder 21 to reset, the speed returns to the initial state, and then the work continues.

[0031] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
