Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to an automatic steel plate welding device. Background Technology

[0002] In the intricate process of steel plate welding, the workpiece and the welding material fuse together under high temperature, forming a crucial molten zone. As heat gradually dissipates, this molten pool cools and solidifies, establishing a stable bond between the materials. However, it is worth noting that during continuous welding operations, the welding rod undergoes a continuous melting process, and its overall length gradually decreases with the accumulation of working time. Therefore, when performing walking welding, the operator must simultaneously perform two key actions: on the one hand, to move forward steadily to ensure the accuracy of the welding path; on the other hand, to continuously apply downward pressure to replenish the welding material as needed. Unfortunately, most of the welding equipment currently widely used relies on manual feeding, which not only increases the labor intensity of the operators but also limits the overall automation level of the welding operation, posing certain challenges to production efficiency and quality control. To address this, we propose an automatic steel plate welding device. Summary of the Invention

It is used to drive the sliding plate to slide along the mounting frame, thereby moving the moving plate and the welding rod on the welding rod clamp. The linkage component is mounted on the mounting frame and connected to the sliding plate. When the sliding plate slides, the linkage component drives the welding rod on the sliding plate, the moving plate and the welding rod clamp to move downward in a direction perpendicular to the sliding direction. The electrode drive assembly is mounted on the sliding plate and connected to the moving plate. The drive end of the electrode drive assembly has a variable motion trajectory, which is used to drive the electrode on the moving plate and the electrode holder to move in a circular or zigzag pattern when the sliding plate slides.

[0007] In some embodiments, the electrode clamping plate includes sliding clamping plates symmetrically arranged on one side of the movable plate. A guide rod is fixedly connected to the movable plate, and the two ends of the guide rod slide through the two sliding clamping plates respectively. A shaft five is fixedly connected to the movable plate, and two screws two are symmetrically fixedly connected to the shaft five. The two screws two pass through the two sliding clamping plates symmetrically. When the shaft five is rotated, it drives the two sliding clamping plates to move to clamp the electrode.

[0008] In some embodiments, the electrode driving assembly includes a shaft six rotatably connected to a sliding plate. One end of the shaft six passes through the sliding plate and is fixedly connected to a connecting rod. The sliding plate is also rotatably connected to a connecting rod via a rotating shaft. One end of each connecting rod is rotatably connected to a round rod. One end of the round rod is located inside a moving plate and is fixedly connected to a limiting round plate. The limiting round plate is rotatably connected to the moving plate. When the shaft six is ​​rotated, it drives the moving plate and the welding electrode to rotate relative to the sliding plate. Furthermore, a shaft seven is rotatably connected to the slider. The shaft six is ​​hollow. One end of the shaft seven is located inside the shaft six and has a sliding groove three. A sliding protrusion three, one end of which is located inside the sliding groove three, is fixedly connected to the inner wall of the shaft six. A helical gear disk is fixedly connected to one end of the shaft seven, and a helical gear disk is also fixedly connected to one end of the worm. The two helical gear disks mesh, and the shaft six is ​​driven to rotate when the worm is rotated.

A connecting plate is provided on one side of the U-shaped frame. The connecting plate is slidably connected to the movable plate. A screw rod is rotatably connected to one side of the movable plate. One end of the screw rod passes through the movable plate and is threaded to it. Rotating the screw rod causes the U-shaped frame to move, thereby releasing the limitation of the limiting circular plate and causing the cylindrical protrusion to embed into the guide rail. Subsequently, rotating the shaft drives the movable plate and the welding rod to reciprocate relative to the movable plate.

[0010] In some embodiments, a half-tooth disk is fixedly connected to the hollow shaft, and moving the hollow shaft causes the half-tooth disk to mesh with the tooth disk.

[0013] This invention has at least the following beneficial effects: This device ingeniously integrates the function of a drive motor, which not only drives the welding rod to perform smooth and precise moving welding operations, but also innovatively designs an automatic lowering feeding system. This system ensures that the welding rod can automatically descend as needed during the welding process, effectively replacing the traditional operation steps that required the operator to manually adjust the position of the welding rod. In this way, not only is work efficiency significantly improved, but the physical burden on the operator is also greatly reduced, making the entire welding process more efficient, convenient and user-friendly.

[0014] Building upon the existing parallel electrode movement welding technology, this device further enhances its mobility. Through a precisely designed electrode drive assembly, it can flexibly control the electrode to weld along various complex trajectories, such as elegant circular motions or efficient zigzag patterns. This innovative welding path selection not only greatly expands the device's applicability, enabling it to meet more diverse welding needs, but also improves the uniformity and quality of the weld by optimizing the welding path, thereby further enhancing the device's adaptability and practicality.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 scope of protection of the present invention.

[0018] Example 1: Please refer to Figures 1-10 The present invention provides a technical solution: an automatic steel plate welding device, including a base 1 and a mounting frame 11 disposed on the base 1, and further comprising: The sliding plate 2 is slidably disposed on one side of the mounting bracket 11; The movable plate 3 is set on one side of the sliding plate 2. The movable plate 3 is equipped with a welding rod clamp 4, which is electrically connected to the external power supply equipment through a wire. The translation drive assembly 5 is mounted on the mounting frame 11 and connected to the sliding plate 2. It is used to drive the sliding plate 2 to slide along the mounting frame 11, thereby driving the moving plate 3 and the welding rod on the welding rod clamp 4 to move. Linkage component 6 is mounted on mounting bracket 11 and connected to movable plate 3. When sliding plate 2 slides, the linkage component 6 drives the sliding plate 2, movable plate 3 and welding rod on welding rod clamp 4 to move downward in a direction perpendicular to the sliding direction. The electrode driving assembly 7 is mounted on the sliding plate 2 and connected to the moving plate 3. The driving end of the electrode driving assembly 7 has a changeable motion trajectory, which is used to drive the electrode on the moving plate 3 and the electrode clamping plate 4 to move in a circular or zigzag pattern when the sliding plate 2 slides. Specifically, this device drives the welding rod to move and weld simultaneously via the drive motor 33, and can also automatically move the welding rod downward for feeding, thus eliminating the need for manual operation by staff, making it more efficient and convenient. Meanwhile, in addition to moving the welding rod in parallel, this device can also drive the welding rod to move in a circular or serrated pattern for welding through the electrode driving component 7, thereby improving the adaptability of the device.

[0019] The translation drive assembly 5 includes a shaft 41 rotatably connected to the mounting bracket 11 via a bearing. A screw 32 is fixedly connected to the shaft 41, and a drive motor 33 is fixedly connected to the mounting bracket 11. The output shaft of the drive motor 33 is connected to the shaft 41. A slider 34 is slidably connected to one side of the mounting bracket 11. One end of the screw 32 passes through the slider 34 and is threadedly connected to it. The slider 34 is connected to the sliding plate 2. By starting the drive motor 33, the shaft 41 is rotated, which in turn rotates the screw 32, thereby moving the slider 34, the sliding plate 2, and the welding rod for welding.

[0020] The linkage component 6 includes a rack 35 fixedly connected to the sliding plate 2, and two racks 35 are symmetrically arranged relative to the sliding plate 2. A connecting rod is fixedly connected to one end of each rack 35. Both racks 35 are in contact with and abut against the slider 34 and are slidably connected to the outer wall of the slider 34. A shaft 36 is rotatably connected to the slider 34 through a bearing. A gear disk 37 that meshes with the rack 35 is fixedly connected to one end of the shaft 36. When the shaft 36 is rotated, the gear disk 37 is rotated, thereby driving the rack 35 and the sliding plate 2 to move. Furthermore, a worm gear 38 is fixedly connected to shaft 2 36, and a worm 39 that meshes with the worm gear 38 is rotatably connected to slider 34. Shaft 3 41 is rotatably connected to mounting bracket 11 via bearing. Shaft 3 41 slides through worm 39. A sliding protrusion 42 is fixedly connected inside worm 39. A sliding groove 43 is opened on shaft 3 41. One end of sliding protrusion 42 is located inside sliding groove 43 and is slidably connected to its inner wall, which is used to slide and limit worm 39. When shaft 3 41 is rotated, worm 39 is driven to rotate, which in turn drives worm gear 38 to rotate, thereby driving shaft 2 36 to rotate. Shaft 3 41 is connected to the output shaft of drive motor 33. Starting drive motor 33 can drive shaft 3 41 to rotate.

[0021] A shaft 44 is rotatably connected to the mounting bracket 11. The shaft 44 is fixedly connected to the output shaft of the drive motor 33. One end of the shaft 41 passes through the mounting bracket 11 and is fixedly connected to the gear disk 45. A hollow shaft 46 is sleeved on the shaft 44. A gear disk 47 that meshes with the gear disk 45 is fixedly connected to the hollow shaft 46. Furthermore, a gear disk 48 is fixedly connected to one end of shaft 3 41, a gear disk 5 49 is fixedly connected to hollow shaft 46, a sliding protrusion 2 51 is fixedly connected inside hollow shaft 46, a sliding groove 2 52 is opened on shaft 44, one end of sliding protrusion 2 51 is located in sliding groove 2 52 and is slidably connected to its inner wall, and moving hollow shaft 46 drives gear disk 5 49 to mesh with gear disk 48; A half-tooth disk 72 is fixedly connected to the hollow shaft 46. Moving the hollow shaft 46 causes the half-tooth disk 72 to mesh with the second tooth disk 45. A strip plate 73 is rotatably connected to the hollow shaft 46 via a bearing, and a screw 74 is rotatably connected to the mounting bracket 11 via a rotating shaft. One end of the screw 74 is threaded through the strip plate 73. A push rod 75 is fixedly connected to one end of the strip plate 73, and an arc-shaped toothed plate 76 that meshes with the toothed disc 48 is fixedly connected to the other end of the push rod 75. This is used to limit the toothed disc 48, and the moving hollow shaft 46 causes the arc-shaped toothed plate 76 to disengage from the toothed disc 48. Specifically, this device has three electrode movement states. The first state is that the moving plate 3 and the welding rod are stationary relative to the sliding plate 2. That is, when the sliding plate 2 moves, the welding rod will only move in a straight line along the steel plate. In this state, the toothed disc 3 47 on the hollow shaft 46 meshes with the toothed disc 2 45, while the toothed disc 5 49 on the hollow shaft 46 does not mesh with the toothed disc 48. At the same time, the arc-shaped toothed plate 76 meshes with the toothed disc 48 to limit the rotation of the toothed disc 48, thereby preventing the welding rod from shaking when moving. At this time, the drive motor 33 is started to drive the shaft 44 to rotate, which in turn drives the hollow shaft 46 to rotate, thereby driving the toothed disc 3 47 and the toothed disc 2 45 to rotate, which in turn drives the shaft 1 41 to rotate, thereby driving the slider 34 to move. The second method involves the moving plate 3 and the welding rod moving in a circular motion relative to the sliding plate 2. That is, when the sliding plate 2 moves, the welding rod not only moves along the steel plate, but also makes a circular motion. In this state, the gear disk 3 47 meshes with the gear disk 2 45, while the gear disk 5 49 also meshes with the gear disk 48. At the same time, the arc-shaped gear plate 76 disengages from the gear disk 48, and the U-shaped frame 66 also limits the limiting circular plate 61, forcing it to rotate only relative to the moving plate 3. At this time, the drive motor 33 is started to drive the shaft 44 to rotate, which in turn drives the hollow shaft 46 to rotate. Thus, the gear disk 3 47 and the gear disk 5 49 drive the gear disk 2 45 and the gear disk 48 to rotate synchronously, which in turn drives the shaft 1 41 and the shaft 3 41 to rotate simultaneously, which in turn drives the moving plate 3 to make a circular motion relative to the sliding plate 2 while moving. The third configuration involves the moving plate 3 and the welding rod reciprocating relative to the sliding plate 2, while performing a sawtooth motion relative to the steel plate. In this state, the half-tooth disc 72 meshes with the toothed disc 49, which meshes with the toothed disc 45, and the toothed disc 48. Simultaneously, the arc-shaped toothed plate 76 disengages from the toothed disc 48, and the U-shaped frame 66 disengages from the limiting circular plate 61. At the same time, the cylindrical protrusion 68 is embedded in the guide rail 67. In this case, the moving plate 3 can only slide relative to the sliding plate 2, while the limiting circular plate 61 can slide relative to the moving plate 3. At this time, the drive motor 33 is started to drive the shaft 44 to rotate, which in turn drives the hollow shaft 46 to rotate. This, in turn, drives the gear disk 47 and the gear disk 49 to drive the gear disk 45 and the gear disk 48 to rotate synchronously, which in turn drives the shaft 41 and the shaft 3 to rotate simultaneously. This causes the moving plate 3 to move back and forth relative to the sliding plate 2 while moving. At the same time, because the half gear disk 72 meshes with the gear disk 45, the shaft 41 is forced to rotate periodically, which makes the movement of the welding rod serrated.

[0022] The electrode clamping plate 4 includes sliding clamping plates 53 symmetrically arranged on one side of the moving plate 3. A guide rod 54 is fixedly connected to the moving plate 3. The two ends of the guide rod 54 slide through the two sliding clamping plates 53 respectively. A shaft 55 is fixedly connected to the moving plate 3. Two screws 56 are symmetrically fixedly connected to the shaft 55. The two screws 56 symmetrically pass through the two sliding clamping plates 53 and are connected to them by threads. The threads of the two screws 56 are opposite in direction. When the shaft 55 is rotated, the two screws 56 are rotated, thereby causing the two sliding clamping plates 53 to move to clamp the electrode.

[0023] The electrode drive assembly 7 includes a shaft 57 rotatably connected to the sliding plate 2 via a bearing. One end of the shaft 57 passes through the sliding plate 2 and is fixedly connected to a connecting rod 58. The sliding plate 2 is also rotatably connected to the connecting rod 58 via a rotating shaft. The two connecting rods 58 are designed in parallel. One end of each connecting rod 58 is rotatably connected to a round rod 59. One end of the round rod 59 is located inside the moving plate 3 and is fixedly connected to a limiting round plate 61. The limiting round plate 61 is rotatably connected to the moving plate 3. When the shaft 57 is rotated, the connecting rod 58 is driven to rotate, thereby driving the moving plate 3 and the welding rod to rotate relative to the sliding plate 2. At the same time, the two parallel connecting rods 58 are used to ensure that the orientation of the moving plate 3 and the welding rod remains unchanged. Furthermore, a shaft 62 is rotatably connected to the slider 34 via a bearing. The shaft 57 is hollow. One end of the shaft 62 is located inside the shaft 57 and has a groove 63. The shaft 62 and the shaft 57 are slidably connected. A sliding protrusion 64 is fixedly connected to the inner wall of the shaft 57, with one end located inside the groove 63. The sliding protrusion 64 is slidably connected to the inner wall of the groove 63. One end of the shaft 62 is fixedly connected to a helical gear disk 65, and one end of the worm 39 is also fixedly connected to a helical gear disk 65. The shaft 41 slides through the helical gear disk 65. The two helical gear disks 65 mesh, and when the worm 39 is rotated, the helical gear disk 65 drives the shaft 57 to rotate.

[0024] A U-shaped frame 66 is slidably connected inside the movable plate 3. One end of the U-shaped frame 66 adopts a stepped design to limit the limiting circular plate 61. A U-shaped guide rail 67 is fixedly connected to one side of the movable plate 2. A cylindrical protrusion 68 is fixedly connected to the U-shaped frame 66. A connecting plate 69 is provided on one side of the U-shaped frame 66. The connecting plate 69 is slidably connected to the movable plate 3. A screw 71 is rotatably connected to one side of the movable plate 3. One end of the screw 71 passes through the movable plate 3 and is threadedly connected to it. Rotating the screw 71 causes the U-shaped frame 66 to move, thereby releasing the limitation of the limiting circular plate 61 and causing the cylindrical protrusion 68 to embed into the guide rail 67. Then, rotating the shaft 57 causes the movable plate 3 and the welding rod to reciprocate relative to the movable plate 2.

[0025] Example 2: Please refer to Figures 1-11 The present invention provides a technical solution: Embodiment 2 is an optimization based on Embodiment 1; A T-shaped plate 77 is rotatably connected to the shaft 36 via a bearing. The T-shaped plate 77 is slidably connected to the rack 35, and a rectangular plate 78 is fixedly connected to one side of the T-shaped plate 77. The rectangular plate 78 is slidably connected to the side wall of the rack 35 and is used to slide and limit the rack 35 to improve the stability of the device.
