Description

Technical Field

[0001] This invention relates to the field of machining technology, and more specifically, to an automatic welding device for slender shaft components of a continuous casting machine. Background Technology

[0002] In the manufacturing of continuous casting machines, slender shaft components are key parts, and their welding quality directly affects the overall performance and operational stability of the continuous casting machine. However, existing welding technologies and equipment face many severe challenges when handling slender shaft components for continuous casting machines.

[0003] Slender shaft components in continuous casting machines are characterized by a large length-to-diameter ratio and poor rigidity, making them highly susceptible to bending, twisting, and wavy deformation during welding. These deformation problems are particularly pronounced when asymmetrical welding is performed or when the weld seam arrangement deviates from the neutral axis. For example, in actual production, uneven weld seam distribution can cause significant deformation of slender shafts under welding thermal stress, severely affecting the dimensional accuracy and form and position tolerances of these components. This can prevent precise assembly with other parts, ultimately impacting the overall operational accuracy and stability of the continuous casting machine.

[0004] Existing automated welding equipment also has many drawbacks. Due to the slender shape of the shaft, traditional fixtures struggle to provide stable support, causing the slender shaft to wobble or shift during welding, resulting in welding position deviations and severely affecting welding accuracy. Furthermore, these devices often cannot be optimized for the specific structure and dimensions of slender shaft components, making it difficult to achieve comprehensive, high-precision welding operations.

[0005] Furthermore, if the vibrations generated during welding are not effectively buffered and damped, they will be transmitted to the workpiece, further aggravating deformation and potentially even causing micro-cracks inside the workpiece, reducing its strength and reliability. Moreover, existing equipment lacks precise control over welding parameters, failing to adjust these parameters accurately and in real-time based on the material and dimensions of slender shaft components, thus making it difficult to guarantee ideal welding quality.

[0006] In summary, existing welding technologies and equipment for slender shaft components in continuous casting machines have serious shortcomings in addressing component deformation, welding quality stability, welding efficiency, shaft stability support, damping and shock absorption, and precise control of welding parameters. Developing a dedicated automated welding device that can effectively solve these problems, improve welding quality and efficiency, and ensure high-precision, high-quality welding of slender shaft components in continuous casting machines is urgently needed. This is of vital importance for promoting technological progress in the continuous casting machine manufacturing industry and enhancing product quality and market competitiveness. Summary of the Invention

[0007] The purpose of this invention is to provide an automatic welding device specifically for slender shaft components of continuous casting machines, so as to solve the problems mentioned in the background art.

[0008] An automatic welding device for slender shaft components of a continuous casting machine includes a welding platform. A pair of limiting plates are fixedly installed at the middle of the upper end of the welding platform. A robotic arm is fixedly installed at the upper end of the welding platform behind the welding head. Feed boxes are fixedly installed on both sides of the welding platform at the welding head. A main control box is fixedly installed on one side of the upper end of the welding platform. An operation panel is fixedly installed on the front side of the main control box. A main control chip is installed inside the main control box. The main control box and the operation panel constitute a main control device. A pair of lower clamping parts are fixedly installed on the lower front side of the welding head. An upper clamping part is provided on the upper end of the welding platform above the lower clamping parts. A transmission wheel is rotatably provided on the middle front side of the limiting plate. A connecting part is slidably provided on the upper middle side of the limiting plate. An auxiliary wheel is rotatably provided on the middle of the connecting part. A buffer structure is provided on the middle of the connecting part. A buffer is fixedly installed on the middle upper end of the limiting plate. An adjusting bolt is rotatably provided on the middle of the buffer. An adjusting stud is threaded on the middle of the adjusting bolt. Four limiting baffles are fixedly installed on the inner side of the feed box. A guide rod is fixedly installed on one side of each limiting baffle. A lifting component is provided in the middle of the guide rod. A first buffer spring is fixedly installed on one side of the lifting component, and a second buffer spring is fixedly installed on the other side of the lifting component. A clamping component is provided in the middle of the guide rod. The robotic arm and the welding head form a welding device. The welding device is electrically connected to the main control device. The transmission wheel, auxiliary wheel, lower clamp, and upper clamp form a stabilizing device.

[0009] Furthermore, a support frame is fixedly installed at the lower end of the welding platform, and a welding head is fixedly installed at the output end of the robotic arm.

[0010] By adopting the above technical solution, the main control box can control the welding head to perform welding operations on slender rods of the continuous casting machine.

[0011] Furthermore, a square groove is provided in the middle of the upper side of the limiting plate, and the connector is slidably disposed inside the square groove on the upper side of the limiting plate. The two front ends of the connector are fixedly connected to the upper end of the upper clamp.

[0012] By adopting the above technical solution, the connecting piece can synchronously drive the upper clamping piece to move up and down, so as to cooperate with the auxiliary wheel to clamp and fix the slender rod of the continuous casting machine. At the same time, it can reduce the rigid stress caused by the upper clamping piece, which would lead to the deformation of the slender rod of the continuous casting machine.

[0013] Furthermore, the buffer structure includes a connecting bearing that is rotatably mounted and fixedly installed in the middle of the connecting member, a shock-absorbing spring that is fixedly installed at the upper end of the connecting bearing, and a circular groove corresponding to the shock-absorbing spring that is opened at the lower end of the adjusting stud.

[0014] By adopting the above technical solution, the height of the adjusting stud can be controlled by rotating the adjusting bolt, thereby adjusting the height of the connecting part.

[0015] Furthermore, an extrusion plate is provided on the upper middle part of the connector. The extrusion plate and the connector are separate structures. Four guide cylinders are fixedly installed on the upper end of the connector. Four circular grooves are opened at the four corners of the extrusion plate.

[0016] By adopting the above technical solution, the extrusion plate can move up and down on the upper side of the connector. The lower end of the adjusting stud will apply pressure to the extrusion plate, thereby applying a certain force to the buffer structure on the lower side and fixing the upper side of the slender rod of the continuous casting machine.

[0017] Furthermore, a drive motor is fixedly installed on the rear center of the limiting plate, and the output end of the drive motor is fixedly connected to the transmission wheel. Both the transmission wheel and the auxiliary wheel are fitted with rubber diaphragms on their outer sides.

[0018] By adopting the above technical solution, the transmission wheel and auxiliary wheel can provide anti-slip protection for the slender rods of the continuous casting machine, and at the same time, the transmission wheel can drive the slender rods of the continuous casting machine to move horizontally to a certain extent.

[0019] Furthermore, a connecting plate is fixedly installed on the side of the limiting plate, and a shock-absorbing plate is fixedly installed on the side of the connecting plate. The connecting plate and the shock-absorbing plate are made of hard rubber.

[0020] By adopting the above technical solutions, the connecting plate and the damping plate can prevent accidents during the welding process. The steel pipe of the slender rod of the continuous casting machine can deform too much. The connecting plate and the damping plate can protect the internal robotic arm and prevent damage.

[0021] Furthermore, the limiting baffle has a through groove in the middle corresponding to the shock absorber, and the four clamping members have a fan-shaped rubber structure at their adjacent ends.

[0022] By adopting the above technical solution, when the slender rod of the continuous casting machine is set in the middle of the clamping component, the four-way clamping component can provide a balanced end clamping force on the slender rod of the continuous casting machine, thereby avoiding the shaking and deformation of the end of the slender rod of the continuous casting machine during the welding process.

[0023] Furthermore, a protective baffle is fixedly installed on the rear center of the limiting plate, and a positioning plate is fixedly installed on the center of the feed box, with a circular through groove in the center of the positioning plate.

[0024] By adopting the above technical solution, operators can feed slender rods from the continuous casting machine into the device for welding through the circular slot in the middle of the positioning plate.

[0025] Compared with the prior art, the advantages of this invention are: 1. In this invention, by providing a structure with a transmission wheel and a connecting piece, a clamping piece and a buffer piece can be used to mechanically clamp the area near the welding position. At the same time, the transmission wheel and the shock-absorbing plate can eliminate the vibration generated during welding, thereby effectively reducing and avoiding problems such as welding bending, twisting, and wave deformation.

[0026] 2. In this invention, by providing a structure with clamping and lifting components, the two ends of the slender rod of the continuous casting machine can be stably reinforced, effectively reducing the shaking and displacement caused by the stress of the slender rod of the continuous casting machine being transmitted to the distant end during welding, thereby increasing the stability of welding.

The front ends of the connector 16 are fixedly connected to the upper end of the upper clamp 13. The connector 16 can synchronously drive the upper clamp 13 to move up and down, so as to cooperate with the auxiliary wheel 17 to clamp and fix the slender rod 10 of the continuous casting machine. At the same time, it can reduce the rigid stress caused by the upper clamp 13, which leads to the deformation of the slender rod 10 of the continuous casting machine.

The height of the adjusting stud 801 moving downward can be controlled by rotating the adjusting bolt 8, thereby adjusting the height of the connecting member 16. An extrusion plate 15 is provided on the upper middle part of the connector 16. The extrusion plate 15 and the connector 16 are separate structures. Four guide cylinders are fixedly installed on the upper end of the connector 16. Four circular grooves are opened at the four corners of the extrusion plate 15. The extrusion plate 15 can move up and down on the upper side of the connector 16.

A drive motor 19 is fixedly installed in the middle of the rear side of the limit plate 3. The output end of the drive motor 19 is fixedly connected to the transmission wheel 4. The outer sides of the transmission wheel 4 and the auxiliary wheel 17 are covered with rubber membranes. The transmission wheel 4 and the auxiliary wheel 17 can provide anti-slip protection for the slender rod 10 of the continuous casting machine. At the same time, the transmission wheel 4 can drive the slender rod 10 of the continuous casting machine to move horizontally to a certain extent. A connecting plate 12 is fixedly installed on the side of the limiting plate 3, and a shock-absorbing plate 18 is fixedly installed on the side of the connecting plate 12. The connecting plate 12 and the shock-absorbing plate 18 are made of hard rubber. The connecting plate 12 and the shock-absorbing plate 18 can prevent accidents from occurring during the welding process. If the steel pipe of the slender rod 10 of the continuous casting machine deforms too much, the connecting plate 12 and the shock-absorbing plate 18 can protect the internal robotic arm 9 and prevent damage. The limiting baffle 24 has a through groove in the middle corresponding to the shock absorber 18. The four clamping members 28 have a fan-shaped rubber structure at one end. When the slender rod 10 of the continuous casting machine is placed in the middle of the clamping member 28, the four-way clamping member 28 can provide a balanced end clamping force on the slender rod 10 of the continuous casting machine, thereby avoiding the shaking and deformation of the end of the slender rod 10 of the continuous casting machine during the welding process. A protective baffle 20 is fixedly installed on the rear middle of the limiting plate 3, and a positioning plate 22 is fixedly installed on the middle of the feed box 6. A circular through groove is opened in the middle of the positioning plate 22, so that the operator can send the slender rod 10 of the continuous casting machine into the device for welding processing through the circular through groove in the middle of the positioning plate 22.

[0031] Working principle of the invention: The operator can pass the slender rod 10 of the continuous casting machine through the middle of the positioning plate 22. One end of the slender rod 10 will push up the clamping member 28. The middle of the limiting baffle 24 has a through groove corresponding to the shock-absorbing plate 18. The four clamping members 28 have a fan-shaped rubber structure at their adjacent ends. When the slender rod 10 of the continuous casting machine is positioned in the middle of the clamping member 28, the four-way clamping members 28 can provide a balanced end clamping force on the slender rod 10 of the continuous casting machine. At the same time, the lifting member 23 can guide the rod. The clamping member 28 moves up and down within a range of 26 to maintain a balanced four-way clamping force at its upper end. Then, the operator inserts one end of the slender rod 10 of the continuous casting machine between the transmission wheel 4 and the auxiliary wheel 17. An extrusion plate 15 is located on the upper center of the connecting member 16. The extrusion plate 15 and the connecting member 16 are separate structures. Four guide cylinders are fixedly installed on the upper end of the connecting member 16. Four corresponding circular grooves are formed at the four corners of the extrusion plate 15. The extrusion plate 15 can move up and down on the upper side of the connecting member 16. Adjusting stud 8... The lower end of 01 applies pressure to the extrusion plate 15, thereby applying a certain force to the buffer structure on the lower side and fixing the upper side of the slender rod 10 of the continuous casting machine. Then, the drive motor 19 is started, and the drive motor 19 aligns the slender rods 10 of the continuous casting machine on both sides through the transmission wheel 4. Then, the robotic arm 9 can weld the slender rods 10 of the continuous casting machine. When the robotic arm 9 is welding, some vibration deformation will occur between the stress components of the metal parts. This device is equipped with a lower clamp 11 and an upper clamp 13 structure, which can rigidly fix the welding position. The middle of the upper clamps 13 on both sides is equipped with an auxiliary wheel 17 and a transmission wheel 4 structure. When the amplitude is too large, the shock-absorbing spring 21 can absorb the excess vibration, while the small vibration impact will be absorbed by the rubber film on the surface of the transmission wheel 4 and the auxiliary wheel 17. During welding, the clamp 28 can witness the stability of the other end of the welding position, thereby effectively avoiding the occurrence of problems such as welding bending, twisting, and wave deformation during the welding process.
