Description

Technical Field

[0001] The utility model relates to the technical field of hot press welding, in particular to a hot press welding jig with multi-directional adjustment. Background Technique

[0002] Welding is an important joining process. It is a processing method that makes the welded parts achieve atomic bonding by heating, applying pressure or both. Welding has the advantages of high connection strength, good sealing performance, flexible process, high production efficiency, etc. When welding, it is necessary to select appropriate welding methods and process parameters, pre-treat the welded parts, ensure the normal operation of welding equipment and tools, and take necessary safety protection measures. In order to provide stable welding pressure and temperature, ensure the firm connection between the welded parts, and improve the welding quality, a hot press welding jig is usually used for welding.

[0003] Traditional hot press welding jigs usually achieve the connection of welded parts by applying pressure and heat. Its principle is to place the welded parts in the jig, then heat the welded parts to a certain temperature through a heating element, and at the same time apply a certain pressure through a pressure mechanism to make the welded parts achieve connection under high temperature and high pressure. This welding method has the advantages of high connection strength, good sealing performance, and simple process, so it has been widely used in the fields of electronics, automobiles, aerospace, etc.

[0004] However, for traditional hot press welding jigs, most of their welding methods are to perform welding operations on workpieces by moving up and down. In this welding mode, the welding parts of the hot press welding jig move up and down along the vertical direction. When welding different positions of the workpiece, due to the limitations of the structure of the jig itself and the welding method, the position of the workpiece will be frequently moved, which will not only increase the workload of the welding work, but also affect the welding accuracy, and it is necessary to readjust the accuracy of its position. Therefore, a hot press welding jig with multi-directional adjustment is proposed to solve the above problems. Content of the Utility Model

[0036] Referring to Figure 1 and Figure 2 , an embodiment provided by the present utility model: a hot pressing and welding jig with multi-directional adjustment, including a workbench 1. A rectangular array of connecting columns 6 is fixedly connected to the top of the workbench 1. The connecting columns 6 are solid cylindrical structures made of high-strength alloy steel, having extremely high compressive strength and wear resistance. A connecting frame 2 is fixedly connected to the top of the workbench 1 to form a strong frame structure. A top plate 3 is fixedly connected to the top of the connecting frame 2. An electric push rod 4 is fixedly connected inside the top plate 3. The output end of the electric push rod 4 is fixedly connected to a lifting plate 5. The lifting plate 5 is slidably connected to the outer wall of the connecting column 6. A sliding hole matching the connecting column 6 is opened inside the lifting plate 5. An appropriate gap is maintained between the outer wall of the connecting column 6 and the inner wall of the sliding hole, so that the lifting plate 5 can slide smoothly on the connecting column 6. A limiting groove 11 is opened inside the lifting plate 5, and the limiting groove 11 ensures the stability and accuracy when the connecting block 14 slides therein. A moving groove 16 is opened inside the lifting plate 5. A motor 12 is fixedly connected inside the lifting plate 5. The output end of the motor 12 is fixedly connected to a transmission belt 13. The transmission belt 13 is made of high-strength rubber material, having good wear resistance and tensile strength. Anti-slip patterns are provided on the surface of the transmission belt 13 to increase the friction with the connecting block 14 and ensure the stability of transmission. A connecting block 14 is fixedly connected to the outer wall of the transmission belt 13. The outer wall of the connecting block 14 is slidably connected inside the limiting groove 11. A translation plate 10 is fixedly connected to the bottom of the connecting block 14. A slider 15 is fixedly connected to the top of the translation plate 10. The outer wall of the slider 15 is slidably connected inside the moving groove 16. A welding rod 9 is provided at the bottom of the translation plate 10. The welding rod 9 is made of a high-temperature-resistant alloy material, having good electrical conductivity and thermal conductivity. The head of the welding rod 9 is specially treated to generate a stable electric arc during the welding process to ensure the welding quality. A control component is fixedly connected to the outer wall of the workbench 1. The control component is used to control the device, so as to conveniently adjust the position of the welding rod 9 and weld different positions of the workpiece.

[0037] Specifically, after preparation, the motor 12 is started according to the welding position. The motor 12 drives the conveyor belt 13 to rotate. Then, the conveyor belt 13 drives the fixed connecting block 14 to slide inside the limiting groove 11. Next, the limiting groove 11 drives the bottom translation plate 10 to move. At the same time, the translation plate 10 drives the slider 15 fixed on the top to slide inside the moving groove 16, thereby driving the welding rod 9 to move horizontally. After that, the device inside the translation plate 10 can be started to drive the welding rod 9 to move vertically. Finally, the electric push rod 4 can be started to lift and lower the lifting plate 5 on the outer wall of the connecting column 6 to weld the workpiece position. It can translate the welding rod 9 in the horizontal and vertical directions, making the welding operation more flexible and diverse, more precisely controlling the welding position, ensuring the welding quality and accuracy, and also being able to meet the welding requirements of workpieces with different shapes and sizes, improving the versatility of the equipment. Thus, the adjustment time during the welding process is reduced, the production efficiency is improved, it can adapt to various complex welding working conditions, and the adaptability and reliability of the equipment are enhanced.

[0038] Refer to Figure 1 , the control component includes a knob 7 and a display screen 8. One side of the knob 7 is rotatably connected to the outer wall of the workbench 1. The knob 7 is a circular operating component made of high-strength plastic material, with good wear resistance and corrosion resistance. The surface of the knob 7 is anti-slip treated with fine patterns engraved, so that the operator can better master the strength and direction during operation. The outer wall of the display screen 8 is fixedly connected inside the workbench 1. The display screen 8 is a rectangular liquid crystal screen, using high-definition display technology, and can clearly display various operating parameters and status information of the device.

[0039] Specifically, the knob 7 makes it simple and intuitive to start the device. The user only needs to gently rotate it to complete the start operation, and through the display screen 8, the temperature status of the welding rod 9 can be displayed in real time, allowing the user to understand the temperature change during the welding process at any time.

[0040] Refer to Figure 1 、 Figure 3 and Figure 4, a fixing plate 23 is fixedly connected to the top of the workbench 1. A clamping groove 24 is formed inside the fixing plate 23. The shape of the clamping groove 24 is semi-circular to ensure a tight fit with the clamping ball 27. A limiting plate 17 is fixedly connected to one side of the fixing plate 23. The function of the limiting plate 17 is to prevent the moving base 18 from disengaging from the fixing plate 23 during the sliding process. A moving base 18 is slidably connected to the outer wall of the fixing plate 23. A slide rail 19 is formed inside the moving base 18. A fixed column 20 is fixedly connected inside the moving base 18. A connecting plate 21 is slidably connected to the outer wall of the fixed column 20. A first spring 22 is sleeved on the outer wall of the fixed column 20. One end of the first spring 22 is fixedly connected to the inner wall of the moving base 18, and the other end of the first spring 22 is fixedly connected to one side of the connecting plate 21. A clamp 26 is fixedly connected to the top of the connecting plate 21. The clamp 26 is made of high-strength plastic and has good wear resistance and corrosion resistance. It can closely fit the surface of the workpiece to ensure firm clamping. An anti-slip pad is provided inside the clamp 26 to increase the friction with the workpiece and prevent the workpiece from sliding during the clamping process. A moving block 25 is fixedly connected to the bottom of the clamp 26. The moving block 25 is a rectangular metal block with good wear resistance and stability. A protrusion matching the slide rail 19 is designed at the bottom of the moving block 25, so that the moving block 25 can slide smoothly in the slide rail 19. The outer wall of the moving block 25 is slidably connected inside the slide rail 19. A sliding column 29 is slidably connected inside the moving base 18. A second spring 28 is sleeved on the outer wall of the sliding column 29. The function of the second spring 28 is to provide a certain elastic force for the clamping ball 27, so that the clamping ball 27 can be tightly stuck in the clamping groove 24. One end of the second spring 28 is fixedly connected to the inside of the moving base 18, and the other end of the second spring 28 is fixedly connected to a clamping ball 27. The outer wall of the clamping ball 27 is slidably connected inside the clamping groove 24, so as to conveniently pull out and fix the clamp 26, providing a wider operating space and facilitating the operator to perform the clamping operation.

[0041] Specifically, first pull the moving base 18. The moving base 18 will drive the sliding column 29 to move. Subsequently, the sliding column 29 will drive the clamping ball 27 to slide inside the clamping groove 24. At the same time, the clamping groove 24 will compress the second spring 28. When the moving base 18 moves out of the device, push the clamp 26. The clamp 26 will drive the connecting plate 21 to slide on the outer wall of the fixed column 20 and compress the first spring 22. At the same time, the clamp 26 will drive the moving block 25 to slide inside the slide rail 19. Then place the workpiece on the top of the moving base 18. Then release the clamp 26. The first spring 22 will rebound to drive the clamp 26 back to its original position, adaptively clamp the workpiece, and keep it stable. Finally, push the moving base 18 back into the device and limit its position through the limiting plate 17 to prevent slipping. Clamping outside the device can more flexibly adjust the position and angle of the clamp 26 to adapt to workpieces of different shapes and sizes, and can more conveniently perform the clamping operation, reducing the operation time and improving the work efficiency. Moreover, when clamping outside the device, the operator can more clearly observe the position and clamping situation of the workpiece, facilitating timely adjustment. And using the spring for adaptive clamping can quickly fix the workpiece, reducing the time for adjusting the position of the workpiece, thereby improving the welding efficiency.

[0042] Working principle: When welding a workpiece, first pull the moving base 18 to drive the sliding column 29 to move through the moving base 18. Then drive the clamping ball 27 to slide inside the clamping groove 24 through the sliding column 29. At the same time, compress the second spring 28 through the clamping groove 24 until the moving base 18 moves out of the device. Then push the clamp 26. Then drive the connecting plate 21 to slide on the outer wall of the fixed column 20 through the clamp 26 and compress the first spring 22. At the same time, drive the moving block 25 to slide inside the slide rail 19. Then place the workpiece on the top of the moving base 18. Then release the clamp 26. The first spring 22 will rebound to drive the clamp 26 back to its original position, adaptively clamp the workpiece, and keep it stable. Then push the moving base 18 back into the device and limit its position through the limiting plate 17 to prevent slipping, thereby fixing the workpiece. Then start the device through the rotary knob 7 and check the temperature status of the welding rod 9 through the display screen 8. After preparation, start the motor 12 according to the welding position. The motor 12 drives the transmission belt 13 to rotate. Then drive the fixed connecting block 14 to slide inside the limiting groove 11 through the transmission belt 13. Then drive the bottom translation plate 10 to move through the limiting groove 11. And drive the slider 15 fixed on the top to slide inside the moving groove 16 through the translation plate 10, thereby driving the welding rod 9 to move horizontally. Then start the device inside the translation plate 10 to drive the welding rod 9 to move vertically. Then start the electric push rod 4 to lift and lower the lifting plate 5 on the outer wall of the connecting column 6 to weld the position of the workpiece.

[0043] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
