Description

Technical Field

[0001] This utility model relates to the field of industrial automation welding technology, specifically a high-precision laser high-temperature preheating welding automation platform. Background Technology

[0002] In the current industrial manufacturing field, welding technology, as a key process for joining metal materials, directly affects product quality and production efficiency in terms of its level of automation and precision. However, traditional welding platforms still have many shortcomings in workpiece transportation and positioning clamping, making it difficult to meet the urgent needs of modern manufacturing for efficient and precise welding.

[0003] Traditional welding platforms often rely on manual operation or semi-automated mechanical devices for workpiece transport. This is not only inefficient but also prone to problems such as workpiece sequence disorder and inaccurate positioning, seriously affecting welding quality and production continuity. Especially in mass production scenarios, manual feeding is labor-intensive and fatigue-prone, leading to unstable feeding speeds that cannot meet the high-speed operation requirements of the production line. In addition, manual operation increases the risk of human error, such as workpiece placement deviations and missed feedings, further reducing the weld pass rate. Traditional welding platforms also have significant shortcomings in workpiece positioning and clamping. Many platforms use fixed clamps or simple mechanical clamping devices, which are difficult to keep the workpiece stable during welding and are easily affected by welding heat deformation, vibration, and other factors, resulting in a decrease in welding accuracy. At the same time, the loading and unloading process of traditional clamps is cumbersome, requiring frequent manual adjustments to the clamp position and force, which is not only time-consuming and labor-intensive but also prone to damaging the workpiece surface, affecting the product's appearance and performance.

[0004] To address the aforementioned issues, this invention proposes a high-precision laser high-temperature preheating welding automated platform. This platform, through an innovatively designed rotary feeding device and automatic clamping device, achieves efficient and orderly conveying and stable positioning and clamping of workpieces. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision automated laser high-temperature preheating welding platform to solve the problems mentioned in the background art.

The circular rod is fixedly connected to the lower surface of the robotic arm, and a limit post is fixedly connected to the surface of the circular rod.

[0008] Preferably, the automatic clamping device further includes a large spring, the lower end of which is fixedly connected to the inner wall of the rectangular groove, and the upper end of which is fixedly connected to a clamp.

[0012] This utility model provides a high-precision automated laser high-temperature preheating welding platform through improvements, which has the following improvements and advantages compared with the prior art:

[0013] Firstly, this utility model achieves efficient and orderly workpiece conveying through a rotary feeding device. This device utilizes the unidirectional transmission characteristics of ratchet and pawl, combined with the precise cooperation of limiting groove and limiting post, to enable the rotating disk to rotate stably in one direction, ensuring that the workpieces are delivered to the processing position one by one in a predetermined order.

[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 high-precision automated laser high-temperature preheating welding platform. The technical solution of this utility model is as follows:

[0024] like Figure 1 - Figure 4 As shown, a high-precision laser high-temperature preheating welding automated platform includes a base 1, a platform 2 movably connected to the upper surface of the base 1, a rotating disk 3 fixedly connected to the upper end of the platform 2, a robotic arm 4 arranged above the rotating disk 3, a welding module 5 fixedly connected to the lower surface of the robotic arm 4, a rotating feeding device arranged inside the rotating disk 3, and an automatic clamping device arranged on the base 1. The rotating feeding device includes a ratchet 6, which is fixed to the inner wall of the rotating disk 3. A circular tube 7 is arranged inside the rotating disk 3, and the lower end of the circular tube 7 is rotatably connected to the upper end of the platform 2. The automatic clamping device includes a rectangular groove 13, which is formed on the upper surface of the base 1.

[0025] Furthermore, the rotary feeding device also includes two symmetrically arranged pawls 8. Each pawl 8 is rotatably connected to the surface of the circular tube 7 through a connector. A small spring 9 is fixedly connected to the side wall of each pawl 8. The end of each small spring 9 away from the pawl 8 is fixedly connected to the surface of the circular tube 7. A limit groove 10 is opened in the inner wall of the circular tube 7. A circular rod 11 is set inside the circular tube 7. The circular rod 11 is fixedly connected to the lower surface of the robotic arm 4. A limit post 12 is fixedly connected to the surface of the circular rod 11. The two pawls 8 are symmetrically arranged with the circular tube 7 as the center and are rotatably connected to the surface of the circular tube 7 through a connector to ensure uniform force distribution and structural stability.

[0026] Furthermore, the automatic clamping device also includes a large spring 14. The lower end of the large spring 14 is fixedly connected to the inner wall of the rectangular groove 13, and the upper end of the large spring 14 is fixedly connected to a clamp 15. A sliding rod 17 is provided on the side wall of the clamp 15. Two symmetrically arranged sliding rods 17 are fixedly connected to the surface of the platform 2. Two symmetrically arranged semi-circular grooves 18 are provided on the upper end of the rotating disk 3. When the rotating disk 3 rotates, the sliding rod 17 on it slides along the sliding groove 16. The inclination angle of the sliding groove 16 matches the rotation direction of the rotating disk 3. When the rotating disk 3 rotates counterclockwise, the sliding rod 17 slides out of the end of the sliding groove 16, the clamp 15 loses its horizontal limit, the large spring 14 drives the clamp 15 to rise, release the workpiece, and the sliding rod 17 slides into the inclined section of the sliding groove 16, forcing the clamp 15 to compress the large spring 14 downward, and accurately clamp the workpiece newly fed into the semi-circular groove 18.

[0027] Furthermore, an annular groove is provided on the upper surface of the base 1, and an annular block is provided at the lower end of the platform 2. The base 1 and the platform 2 are rotatably connected through the annular groove and the annular block. The annular block is embedded in the annular groove, and the platform 2 achieves rotational movement around the central axis of the base 1 by sliding the annular block in the annular groove.

[0028] Furthermore, each pawl 8 is matched with the ratchet 6, the size of the limiting post 12 is matched with the size of the limiting groove 10, the limiting post 12 is slidably connected to the inner wall of the limiting groove 10, and a small spring 9 is fixed to the side wall of each pawl 8. The other end of the small spring 9 is fixed to the round tube 7 to provide a constant inward elastic force. This design enables the pawl 8 to accurately switch between "compression" and "engagement" states when the robotic arm 4 is raised and lowered, realizing the unidirectional transmission of the ratchet 6.

[0029] Furthermore, the clamp 15 is slidably connected to the inner wall of the rectangular groove 13, the arc-shaped part of the clamp 15 matches the semi-circular groove 18, each slide rod 17 is directly below the adjacent semi-circular groove 18, each round tube 7 is slidably connected to the inner wall of the slide groove 16, the limiting groove 10 opened on the inner wall of the round tube 7 forms a sliding fit with the limiting post 12 fixed on the surface of the round rod 11, when the robotic arm 4 moves linearly, the limiting post 12 slides along the limiting groove 10, forcibly driving the round tube 7 to rotate clockwise or counterclockwise.

[0030] Working principle: During use, two workpieces are placed in the semi-circular groove 18. The workpiece directly below the welding module 5 is pressed down by the arc-shaped part of the clamp 15, fixing it in the semi-circular groove 18. Then, the equipment is turned on, and the robotic arm 4 descends. As the robotic arm 4 descends, it drives the circular rod 11 to descend, and the circular rod 11 drives the limiting post 12 to descend. Since the robotic arm 4 can only move linearly, the circular rod 11 and the limiting post 12 can also only move linearly. The limiting post 12 is in the limiting groove 10, pressing against the inner wall of the limiting groove 10, thus forcing the circular tube 7 to rotate clockwise. The circular tube 7 drives the pawl 8 and the small spring 9. When the pawl 8 rotates clockwise within the limiting groove 10, it compresses the small spring 9, allowing the small spring 9 to rotate smoothly on the inner wall of the limiting groove 10. At this time, the clockwise rotation of the circular tube 7 will not cause the limiting groove 10 to rotate. When the robotic arm 4 descends to a point where it will not descend further, the welding module 5 begins to work, performing partial moving welding above the semi-circular groove 18. When the welding of this workpiece is completed, the robotic arm 4 rises, causing the circular rod 11 to move upwards. When the circular rod 11 moves the limiting post 12 upwards, the limiting post 12 acts on the limiting groove 10, forcing the circular tube 7 to rotate counterclockwise. The round tube 7 drives the pawl 8 and the small spring 9 to rotate counterclockwise. When the pawl 8 rotates counterclockwise, it is locked in the limiting groove 10 by the elastic force of the small spring 9, thus causing the limiting groove 10 to rotate counterclockwise as well. The limiting groove 10 drives the rotating disk 3 to rotate counterclockwise. When the rotating disk 3 rotates counterclockwise, it drives the sliding rod 17 and the platform 2 to move together. The sliding rod 17 in the sliding groove 16 slides out of the sliding groove 16, so that the clamp 15 is no longer controlled by the sliding rod 17. Under the action of the large spring 14, the clamp 15 moves upward, releasing the fixation on the clamped workpiece, so that the workpiece moves with the rotating disk 3. The rotating part moves away from below the fixture 15, while another workpiece is fed directly below the arc-shaped part of the fixture 15 due to the rotation of the rotating disk 3. During the feeding process, another slide rod 17 slides into the slide groove 16. Due to the inclined setting of the slide groove 16, the movement of the slide rod 17 in the slide groove 16 forces the fixture 15 to compress the large spring 14 and descend, which just presses down on the workpiece that has just been fed. Then the robotic arm 4 rises to a stop and then descends to prepare for welding. Similarly, at this time, the rotating disk 3 of the round rod 11 will not rotate, and the fixture 15 will not move. This equipment realizes automatic feeding and welding in this way.
