Description

Technical Field

[0001] This utility model relates to the field of wire extension technology for arc welding machines, and in particular to a wire extension device for arc welding machines. Background Technology

[0002] The wire feeding mechanism of an arc welding machine is mainly used in automatic or semi-automatic arc welding equipment. Its function is to stably feed the welding wire to the welding area according to a set speed and method during the welding process. This is crucial for ensuring welding quality and the continuity of the welding process.

[0003] However, in the existing technology, different welding processes and weld shape requirements need to be achieved by adjusting the welding wire angle. Common wire feeders have low degree of freedom when adjusting the wire feed angle. However, different raw materials and product requirements often require different wire feed angles. Once the angle freedom of the wire feeder is low, it is difficult to meet the diverse production needs. Especially in some complex and high-precision welding tasks, it cannot flexibly adapt to the diversity of materials, changes in welding positions, and welding process requirements. Utility Model Content

[0004] The purpose of this invention is to solve the problem of low degree of freedom in adjusting the angle of wire feeding in common existing wire feeding devices, and to propose a wire feeding device for arc welding machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wire feeding device for an arc welding machine, comprising a support frame and a fixed frame fixedly connected to its top, a wire feeding mechanism installed above the fixed frame, and a movable mechanism installed on one side of the top of the support frame; The active mechanism includes a second mounting frame, a rotating frame rotatably connected to one side of the second mounting frame, a second connecting rod rotatably connected to the inner side of one end of the rotating frame, a first swing rod fixedly connected to the outer surface of one end of the second connecting rod, a first connecting rod rotatably connected to one end of the first swing rod, a first belt component mounted on the outer surface of one end of the first connecting rod, and a second belt component rotatably connected to the outer surface of the other end of the first connecting rod, a second swing rod rotatably connected to the outer surface of the middle part of the first connecting rod, a rotating rod rotatably connected to the inner side of one end of the second swing rod, a second belt component fixedly connected to the outer surface of the rotating rod, a wire-adding frame fixedly connected to the outer surface of the other end of the rotating rod, a limit frame fixedly connected to one end of the rotating frame, a guide rod slidably connected to the inner side of one end of the limit frame, and a guide rod fixedly connected to the wire-adding frame at one end.

[0006] Preferably, a first servo motor is installed inside the second mounting bracket, the output end of the first servo motor is fixedly connected to the rotating bracket, and the bottom end of the first belt component is fixedly connected to the rotating bracket.

[0007] Preferably, a second servo motor is installed on one side of the rotating frame, and the output end of the second servo motor is fixedly connected to the second connecting rod.

[0008] Preferably, the filament-adding mechanism includes a first mounting frame and a support rod. A take-up drum is rotatably connected to the top of one end of the support rod. A first gear is rotatably connected to the center of the inner side of the first mounting frame. Second gears are meshed on both sides of the first gear. A first filament-adding wheel is fixedly connected to one end of the second gear.

[0009] Preferably, a second feeding wheel is provided above the first feeding wheel, the second feeding wheel is rotatably connected to the side wall of the first mounting frame, an output rod is rotatably connected to the other side of the first mounting frame, one end of the output rod is fixedly connected to the first gear, and two guide frames are fixedly connected to one side of the first mounting frame.

[0010] Preferably, a cylinder is fixedly connected to the inner side of the fixing frame, and the output end of the cylinder is fixedly connected to the bottom of the first mounting frame.

[0011] Preferably, a track is fixedly connected to one side of the top of the fixing frame, and the track is slidably connected to the bottom of the first mounting frame.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the second connecting rod is driven to rotate by the second servo motor, causing the first swing rod to move around it. This drives the first connecting rod and its connected first belt component to move synchronously, thereby providing support and movement restriction for the filament feeder, ensuring the independence of the system. The rotation of the first connecting rod triggers the independent movement of the second swing rod, which in turn drives the second belt component to move synchronously, achieving precise angle adjustment of the filament feeder. At the same time, the guide rod is constrained by the positioning frame, ensuring that the filament feeder only adjusts its angle and maintains a horizontal position. The overall design enhances the stability and flexibility of the system, meets diverse filament feeder needs, and improves efficiency.

[0013] 2. In this utility model, during the wire feeding process, the drive output rod transmits power to the first gear through the transmission system, ensuring that the two first wire feeding wheels rotate synchronously. This drives the second gear and its connected second wire feeding wheel, precisely feeding the welding wire from the take-up drum to the wire feeding device. This mechanical coordination ensures efficient and uniform supply of welding wire, preparing the welding operation. The guide frame effectively maintains the correct direction of the welding wire, preventing knots or misalignment, improving wire feeding accuracy and reducing the risk of failure, ensuring a stable and continuous supply of welding wire during the welding process. The cylinder provides precise movement capability for the first mounting frame, enabling the equipment to flexibly adjust the wire feeding position to meet different working requirements.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a wire feeding device for an arc welding machine, including a support frame 1 and a fixed frame 2 fixedly connected to its top. A wire feeding mechanism 3 is installed above the fixed frame 2, and a movable mechanism 4 is installed on one side of the top of the support frame 1. The active mechanism 4 includes a second mounting frame 41. A rotating frame 42 is rotatably connected to one side of the second mounting frame 41. A second connecting rod 432 is rotatably connected to the inner side of one end of the rotating frame 42. A first swing rod 43 is fixedly connected to the outer surface of one end of the second connecting rod 432. A first connecting rod 431 is rotatably connected to one end of the first swing rod 43. A first belt component 44 is installed on the outer surface of one end of the first connecting rod 431, and a second belt component 45 is rotatably connected to the outer surface of the other end of the first connecting rod 431. A second swing rod 46 is rotatably connected to the outer surface of the middle part of the first connecting rod 431. A rotating rod 461 is rotatably connected to the inner side of one end of the second swing rod 46. One end of the second belt component 45 is fixedly connected to the outer surface of the rotating rod 461. A wire-adding frame 47 is fixedly connected to the outer surface of the other end of the rotating rod 461. A limit frame 48 is fixedly connected to one end of the rotating frame 42. A guide rod 49 is slidably connected to the inner side of one end of the limit frame 48. One end of the guide rod 49 is fixedly connected to the wire-adding frame 47.

[0019] A first servo motor 411 is mounted inside the second mounting bracket 41. The output end of the first servo motor 411 is fixedly connected to the rotating bracket 42. The bottom end of the first belt component 44 is fixedly connected to the rotating bracket 42. A second servo motor 421 is mounted on one side of the rotating bracket 42. The output end of the second servo motor 421 is fixedly connected to the second connecting rod 432.

[0020] The specific settings and functions of this embodiment are described below. When the second servo motor 421 drives the second connecting rod 432 to rotate, the second connecting rod 432, through its connection with the first swing rod 43, causes the first swing rod 43 to rotate around the second connecting rod 432 as its center. During this process, the angle change of the first swing rod 43 causes the position adjustment of the first connecting rod 431, and the movement of the first connecting rod 431 drives the synchronous movement of the first belt component 44 connected to it. The synergistic effect of the first belt component 44 and the first swing rod 43 not only provides support but also limits the range of motion of the first swing rod 43, thereby ensuring that the second swing rod 46 does not move with the first swing rod 43, maintaining the independence and stability of the system.

[0021] Meanwhile, the rotation of the first connecting rod 431 causes the second swing rod 46 to rotate relative to the first connecting rod 431. This relative rotation guides the independent movement of the second swing rod 46, thereby driving the second belt component 45 to move synchronously. During the movement of the second swing rod 46, the wire feeder 47 also moves accordingly. The guide rod 49 on one side of the wire feeder 47 moves within a limited range inside the limiting frame 48. The constraint of the limiting frame 48 on the guide rod 49 ensures that the wire feeder 47 can only adjust its angle and cannot change its horizontal position. The reaction force of this structural design is transmitted to the second swing rod 46, thereby maintaining its horizontal movement when the second swing rod 46 moves, further improving the stability of the system.

[0022] When adjusting the angle or position, the fiber feeder 47 rotates synchronously with the rotating rod 461, thereby driving the rotation of both ends of the second belt component 45. Through the belt drive characteristics on the surface of the second belt component 45, relative rotation is achieved between it and the first connecting rod 431. Using the driving function of the first servo motor 411, the rotating frame 42 can be rotated, thus flexibly adjusting the positions of the rotating frame 42, the fiber feeder 47, and other components. This design provides greater freedom of movement for the fiber feeder 47, especially during the fiber feed process, allowing for flexible adjustment of the working angle and position of the fiber feeder 47 to adapt to diverse fiber feed needs and improve work efficiency.

[0023] Example 2: Figure 3 and Figure 4 As shown, the fiber-adding mechanism 3 includes a first mounting frame 31 and a support rod 33. A take-up drum 32 is rotatably connected to the top of one end of the support rod 33. A first gear 35 is rotatably connected to the center of the inner side of the first mounting frame 31. Second gears 36 are meshed on both sides of the first gear 35. A first fiber-adding wheel 37 is fixedly connected to one end of the second gear 36. A second fiber-adding wheel 38 is disposed above the first fiber-adding wheel 37. The second fiber-adding wheel 38 is rotatably connected to the side wall of the first mounting frame 31. An output rod 34 is rotatably connected to the other side of the first mounting frame 31. One end of the output rod 34 is fixedly connected to the first gear 35. Two guide frames 39 are fixedly connected to one side of the first mounting frame 31. A cylinder 21 is fixedly connected to the inner side of the fixed frame 2. The output end of the cylinder 21 is fixedly connected to the bottom of the first mounting frame 31. A track 22 is fixedly connected to one side of the top of the fixed frame 2. The track 22 is slidably connected to the bottom of the first mounting frame 31.

[0024] The overall effect of this embodiment is that, during the wire feeding process, the drive output rod 34 transmits power to the first gear 35 through its transmission system. The rotation of the first gear 35 not only drives the two first wire feeding wheels 37, but also ensures that these two wheels rotate simultaneously, thereby synchronously driving the connected second gear 36. As the second gear 36 rotates, the two second wire feeding wheels 38 begin to work together, precisely performing the wire feeding operation, conveying the welding wire wound on the surface of the take-up drum 32 to the first wire feeding wheel 37. Through this series of mechanical coordination, the welding wire is efficiently and evenly fed into the wire feeding device, preparing for subsequent welding operations.

[0025] In this process, the guide frame 39 plays a crucial guiding role. The design of the guide frame 39 ensures that the welding wire maintains the correct direction throughout the wire feeding process, thus preventing tangling or misalignment. This not only improves the accuracy of wire feeding but also reduces the risk of equipment failure or operational errors, ensuring the stability and continuity of the welding wire supply during welding.

[0026] Furthermore, the driving mechanism of cylinder 21 provides the necessary mobility for the first mounting frame 31, enabling it to move precisely on the surface of track 22. Through the control of cylinder 21, the first mounting frame 31 can adjust its position as needed, achieving more precise wire feeding operations. This characteristic of cylinder 21 drive allows the equipment to flexibly respond to different work requirements during wire feeding.

[0027] The device's operation and working principle are as follows: When the second servo motor 421 drives the second connecting rod 432 to rotate, the second connecting rod 432 drives the first swing rod 43 to rotate around the second connecting rod 432. During this process, the first swing rod 43 changes the position of the first connecting rod 431, and the first belt component 44 moves synchronously with the first swing rod 43 to provide support and restraint, ensuring that the second swing rod 46 does not move with the first swing rod 43. At this time, a relative rotation occurs between the second swing rod 46 and the first connecting rod 431.

[0028] Therefore, the second swing rod 46 moves together with the second belt component 45. When the second swing rod 46 moves, it drives the wire feeder 47 to move synchronously. Because the guide rod 49 on one side of the wire feeder 47 is restricted in its movement inside the limiting frame 48, the wire feeder 47 can only change its angle, while its horizontal position remains unchanged. In this way, the angle change of the wire feeder 47 will have a reaction effect on the second swing rod 46, so that the second swing rod 46 maintains horizontal movement during the movement.

[0029] During adjustment, the fiber feeder 47 rotates synchronously with the rotating rod 461, thereby driving the two ends of the second belt component 45 to rotate, achieving relative rotation with the first connecting rod 431 through the belt drive mechanism. By using the first servo motor 411 to drive the rotating frame 42 to rotate, the positions of components such as the rotating frame 42 and the fiber feeder 47 can be adjusted, thereby improving the degree of freedom of the fiber feeder 47 during fiber feeding.

[0030] During the wire feeding process, the drive output rod 34 transmits power to the first gear 35, causing it to simultaneously apply force to the two first wire feeding wheels 37, thereby driving them to rotate synchronously. This, in turn, drives the connected second gear 36 to cooperate with the two second wire feeding wheels 38 to feed the welding wire on the surface of the take-up drum 32 to the first wire feeding wheels 37. The guide frame 39 plays a guiding role in this process, ensuring accurate wire feeding.

[0031] Driven by cylinder 21, the first mounting bracket 31 can be moved along the surface of track 22 to achieve more precise wire feeding.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
