Description

Technical Field

[0001] This utility model relates to the field of welding robot technology, specifically a multi-head welding robot. Background Technology

[0002] A welding robot is an automated device controlled by a computer program that can autonomously complete welding tasks. It sets welding trajectories and parameters through programming or teaching to achieve high-precision welding of materials such as metals and alloys. Its core function is to replace traditional manual welding, improving efficiency, quality and safety.

[0003] A search revealed a Chinese patent document, publication number CN217096319U, which discloses a cooling device for robotic welding, relating to the field of robotic welding. The device includes a welding robot with a welding torch fixedly connected to one end. A cooling ring is fixedly connected to the surface of the welding torch. The inner wall of the cooling ring has an annular cooling cavity, and the inner wall of the annular cooling cavity has multiple strip-shaped openings. Strip-shaped heat-conducting plates are fixedly connected to the inner walls of each of the multiple strip-shaped heat-conducting plates. An arc-shaped heat-conducting plate is fixedly connected to one side of each of the multiple arc-shaped heat-conducting plates, and one side of each arc-shaped heat-conducting plate is fixedly connected to the surface of the welding torch. This invention allows coolant to be injected into the cooling ring on the surface of the welding torch during welding operations, and then heat and high temperatures are dissipated and cooled through heat conduction. This enables the welding torch on the welding robot to work for extended periods and extends the service life of the welding robot.

[0004] However, the above technologies still have certain shortcomings. For example, when the robot performs welding, it uses a single welding head. However, a single welding head can only handle one welding task, which limits the improvement of the production cycle. Moreover, the welding efficiency of a single welding head is low and cannot meet the needs of modern industry for high-efficiency production. Therefore, we provide a multi-head welding robot to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a multi-head welding robot.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-head welding robot, comprising a mechanical base and a mechanical arm, wherein the bottom end of the mechanical arm is fixedly connected to the top end of the mechanical base, and a mounting base is fixedly connected to the top end of the mechanical arm; two support blocks are fixedly connected to the top end of the mounting base, and two worktables are fixedly connected to one side of each of the two support blocks; welding mechanisms are respectively provided on both sides of the worktables, and a limit plate is movably connected to the outer wall of the welding mechanism; an electric push rod is fixedly connected to one side of the limit plate, and a mounting block is fixedly connected to one end of the electric push rod; a suction cup is threadedly connected to one side of the mounting block; an adjustment mechanism is fixedly connected to the bottom end of the mechanical base, and a base is rotatably connected to the bottom end of the mechanical base.

[0007] The welding mechanism described above includes a cylinder, a welding torch, a welding torch chuck, and a welding torch holder. The output end of the cylinder is fixedly connected to one end of the welding torch, and the other end of the welding torch is fixedly connected to one end of the welding torch chuck.

[0009] As described above, the bottom end of the welding torch holder is fixedly connected to one side of the workbench, and the outer wall of the welding torch passes through the limiting plate and is fixedly connected to the welding torch clamp.

[0010] The aforementioned adjusting mechanism includes a worm, a worm wheel, and a rotating rod. The worm wheel meshes with the worm, and the interior of the worm wheel is fixedly connected to the outer wall of the rotating rod.

[0011] As described above, a servo motor is fixedly connected to one end of the worm gear, and the servo motor is located on the outside of the base. The top end of the rotating rod passes through the base and is fixedly connected to the inside of the mechanical base.

[0012] As mentioned above, the bottom end of the rotating rod is rotatably connected to the inner bottom of the base.

[0013] Compared with existing technologies, this multi-head welding robot has the following advantages:

[0014] I. This utility model, through its welding mechanism, enables the controller to simultaneously activate two sets of cylinders, pushing the welding torch to slide linearly along the inside of the welding torch holder.

[0022] 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.

[0023] like Figure 1-4As shown, this utility model provides a technical solution: a multi-head welding robot, including a mechanical base 1 and a mechanical arm 2. The bottom end of the mechanical arm 2 is fixedly connected to the top end of the mechanical base 1, and a mounting base 3 is fixedly connected to the top end of the mechanical arm 2. Two support blocks 4 are fixedly connected to the top end of the mounting base 3, and two worktables 5 are fixedly connected to one side of each of the two support blocks 4. Welding mechanisms 8 are respectively provided on both sides of the worktables 5, and a limiting plate 6 is movably connected to the outer wall of the welding mechanism 8. An electric push rod 7 is fixedly connected to one side of the limiting plate 6, and a mounting block 10 is fixedly connected to one end of the electric push rod 7. A suction cup 11 is threadedly connected to one side of the mounting block 10. An adjustment mechanism 9 is fixedly connected to the bottom end of the mechanical base 1, and a base 12 is rotatably connected to the bottom end of the mechanical base 1.

[0024] This multi-head welding robot achieves multi-station welding through the coordinated movement of the robotic arm 2 and the adjustment mechanism 9. The robotic arm 2 is fixedly connected to the mechanical base 1, and the mounting base 3 fixes the double worktable 5 through the support block 4, so that the two welding mechanisms 8 can work synchronously. Before welding, the controller drives the electric push rod 7 to adjust the position of the suction cup 11. The suction cup 11, which cooperates with the parts in the welding mechanism 8, enables the robot to stably pick up and position the nameplate, ensuring the accuracy and consistency of the welding process. The adjustment mechanism 9 controls the rotation of the mechanical base 1 and the base 12, driving the robotic arm 2 to rotate vertically as a whole and switch welding positions. The multiple welding mechanisms 8 are symmetrically distributed based on the worktable 5. The robot can complete the welding of multiple nameplates in sequence when it reaches the welding position, and then return. This process optimization reduces the robot's idle time and waiting time, and improves the overall work efficiency.

[0025] like Figure 1-2 As shown, the welding mechanism 8 includes a cylinder 801, a welding torch 802, a welding torch chuck 803, and a welding torch holder 804. The output end of the cylinder 801 is fixedly connected to one end of the welding torch 802, and the other end of the welding torch 802 is fixedly connected to one end of the welding torch chuck 803. The outer wall of the welding torch 802 is movably connected to the inside of the welding torch holder 804. Two cylinder seats are fixedly connected to the outer wall of the cylinder 801, and the bottom end of the cylinder seat is fixedly connected to one side of the worktable 5. The bottom end of the welding torch holder 804 is fixedly connected to one side of the worktable 5. The outer wall of the welding torch 802 passes through the limiting plate 6 and is fixedly connected to the welding torch chuck 803.

[0026] The controller synchronously starts two sets of cylinders 801, pushing the welding torch 802 to slide linearly along the inside of the welding torch holder 804. The welding torch chuck 803 follows suit to complete the welding stud pressing and welding. The movable connection between the welding torch 802 and the welding torch holder 804 provides axial freedom. The limiting plate 6 constrains the radial offset of the welding torch 802. The symmetrical support structure of the double cylinder holder 13 suppresses vibration, realizing parallel welding at two stations. It also allows the robot to handle multiple welding tasks simultaneously in a single operation, significantly improving welding efficiency and production cycle time.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, the adjustment mechanism 9 includes a worm 901, a worm wheel 902, and a rotating rod 903. The worm wheel 902 meshes with the worm 901, and the interior of the worm wheel 902 is fixedly connected to the outer wall of the rotating rod 903. One end of the worm 901 is fixedly connected to a servo motor 14, and the servo motor 14 is located on the outside of the base 12. The top end of the rotating rod 903 passes through the base 12 and is fixedly connected to the interior of the mechanical base 1. The bottom end of the rotating rod 903 is rotatably connected to the inner bottom of the base 12.

[0028] The servo motor 14 is started by the controller, which drives the worm gear 901 to rotate. The worm gear 901 meshes with the worm wheel 902, which forces the worm wheel 902 to drive the rotating rod 903 to rotate. In turn, the rotating rod 903 drives the mechanical base 1 and the mechanical arm 2 to rotate as a whole, which can realize the horizontal angle adjustment of the welding device, thereby adapting to the spatial requirements of complex welding scenarios.

[0029] Working principle: First, the servo motor 14 is started by the controller, which drives the worm gear 901 to rotate. The worm gear 901 meshes with the worm wheel 902, forcing the worm wheel 902 to drive the rotating rod 903 to rotate. In turn, the rotating rod 903 drives the mechanical base 1 and the mechanical arm 2 to rotate as a whole, which can realize the horizontal angle adjustment of the welding device. Second, before welding, the controller drives the electric push rod 7 to adjust the position of the suction cup 11 so that it cooperates with the welding gun chuck 803. Finally, the controller simultaneously starts two sets of cylinders 801, pushing the welding gun 802 to slide linearly along the inside of the welding gun base 804. The welding gun chuck 803 follows to complete the welding nail pressing and welding. The movable connection between the welding gun 802 and the welding gun base 804 provides axial freedom. The limiting plate 6 restricts the radial offset of the welding gun 802. The symmetrical support structure of the double cylinder base 13 suppresses vibration and realizes parallel welding at two stations.
