Description

Technical Field

[0001] This utility model relates to the field of steel pipe beveling technology, and in particular to an automatic steel pipe beveling and grinding device. Background Technology

[0002] Beveling is a crucial step before pipe welding. It involves creating a bevel at a specific angle at the pipe end through cutting, grinding, or other methods to ensure weld quality. Common processing methods include machining (such as lathes and beveling machines), flame cutting (suitable for thick-walled steel pipes), and plasma cutting (high precision). The appropriate method must be selected based on the steel pipe material, wall thickness, and welding process.

[0003] Steel pipe beveling can be automated or manual. Both methods require a fixing mechanism to secure the steel pipe during processing. When processing larger steel pipes, machines are typically used for direct hoisting. However, this method is cumbersome for loading and unloading, requiring a crane to move the pipe horizontally, increasing the difficulty and reducing the device's practicality. Therefore, this invention proposes an automatic steel pipe beveling device to solve these problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes an automatic steel pipe beveling and grinding device, which solves the problem that the existing technology makes it inconvenient to load and unload steel pipes, increasing the difficulty of loading and unloading and thus reducing the practicality of the device in use.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: an automatic steel pipe beveling and grinding device, including a base plate, a beveling machine body installed on one side of the top of the base plate, a grinding tool installed on one side of the beveling machine body, a base installed at the middle position of the top of the base plate and on the other side of the top of the base plate, a positioning plate installed above the base, a moving mechanism provided at the rear end below the positioning plate, and an adjustment mechanism provided below the beveling machine body;

[0006] The moving mechanism includes a mounting cavity, a first servo motor, a first bevel gear, a second bevel gear, a threaded rod, a threaded sleeve, a moving cavity, a fixed cavity, and a limiting structure. The mounting cavity is installed at the rear end of the top of the base plate. The first servo motor is installed on the lower side of one side of the mounting cavity. The first bevel gear is installed on the lower side of the inner side of the mounting cavity. The output end of the first servo motor is connected to one end of the first bevel gear. The second bevel gear meshes with the upper part of the first bevel gear. A threaded rod is installed at the top of the second bevel gear. A threaded sleeve is provided on the outer wall of the threaded rod. The moving cavity is fixedly installed on the outer wall of the threaded sleeve. The fixed cavity is installed at the top of the moving cavity.

[0007] A further improvement is that the limiting structure includes a limiting groove and a limiting block. The limiting groove is opened on both sides inside the mounting cavity, and the limiting block is provided inside the limiting groove. One end of the limiting block is connected to the outside of the moving cavity.

[0008] A further improvement is made in that: a second servo motor is installed at one end of the fixed cavity, a worm gear is installed at one end inside the fixed cavity, the output end of the second servo motor is connected to one end of the worm gear, a worm wheel is engaged on one side of the worm gear, and the top end of the worm wheel is connected to the bottom end of the positioning plate.

[0009] A further improvement is that anti-slip particles are installed on the inner sides of both the base and the positioning plate, and multiple anti-slip particles are respectively arranged inside the base and the positioning plate.

[0010] A further improvement is made in that: the adjustment mechanism includes an electric telescopic rod, a guide rod, and a guide sleeve. The electric telescopic rod is installed on the top of the base plate, and the top of the electric telescopic rod is connected to the bottom of the beveling machine body. A guide rod is installed at the rear end of the top of the base plate, and a guide sleeve is provided on the outer side wall of the guide rod. One end of the guide sleeve is connected to one end of the beveling machine body.

[0011] A further improvement is that the cross-section of the guide rod is smaller than the cross-section of the guide sleeve, and the guide rod and the guide sleeve form a sliding structure.

[0012] The beneficial effects of this utility model are as follows: By providing a moving mechanism at the rear end below the positioning plate, the positioning plate can be rotated and lowered by the cooperation of the mounting cavity, the first servo motor, the first bevel gear, the second bevel gear, the threaded rod, the threaded sleeve, the moving cavity, the limiting groove, the limiting block, the fixed cavity, the second servo motor, the worm gear, and the worm wheel. This makes it easier and faster for the base and the positioning plate to clamp the steel pipe, thus greatly improving the convenience of the device in use. By providing an adjustment mechanism below the beveling machine body, the height of the beveling machine body and the grinding tool can be adjusted by the cooperation of the electric telescopic rod, the guide rod, and the guide sleeve of the adjustment mechanism. This allows the beveling machine body and the grinding tool to be adjusted according to the actual situation of the steel pipe during use, and to process different types of steel pipes, thus greatly improving the versatility of the device in use.

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2As shown in Figures 3 and 4, this embodiment proposes an automatic steel pipe beveling and grinding device, including a base plate 1. A beveling machine body 2 is installed on one side of the top of the base plate 1. A grinding tool 3 is installed on one side of the beveling machine body 2. A base 4 is installed at the middle position of the top of the base plate 1 and on the other side of the top of the base plate 1. A positioning plate 5 is installed above the base 4. A moving mechanism is provided at the rear end below the positioning plate 5. An adjustment mechanism is provided below the beveling machine body 2.

[0020] The moving mechanism includes a mounting cavity 7, a first servo motor 8, a first bevel gear 9, a second bevel gear 10, a threaded rod 11, a threaded sleeve 12, a moving cavity 13, a fixed cavity 16, and a limiting structure. The mounting cavity 7 is mounted on the rear end of the top of the base plate 1. The first servo motor 8 is mounted on the lower side of one side of the mounting cavity 7. The first bevel gear 9 is mounted on the lower side of one side inside the mounting cavity 7. The output end of the first servo motor 8 is connected to one end of the first bevel gear 9. The second bevel gear 10 meshes with the upper part of the first bevel gear 9. The threaded rod 11 is mounted on the top of the second bevel gear 10. 1. A threaded sleeve 12 is provided on the outer wall of the threaded rod 11. A movable cavity 13 is fixedly installed on the outer wall of the threaded sleeve 12. A fixed cavity 16 is installed at the top of the movable cavity 13. A second servo motor 17 is installed at one end of the fixed cavity 16. A worm gear 18 is installed at one end inside the fixed cavity 16. The output end of the second servo motor 17 is connected to one end of the worm gear 18. A worm wheel 19 meshes with one side of the worm gear 18. The top end of the worm wheel 19 is connected to the bottom end of the positioning plate 5. In use, the steel pipe is placed above the base 4, and one end of the steel pipe extends to the inside of the grinding tool 3. Then, the second servo motor 17 is started to drive the worm gear 18 to rotate. Since the worm gear 18 and the worm wheel 19 are meshed, the worm wheel 19 drives the positioning plate 5 to rotate, so that the positioning plate 5 is directly above the base 4. Then, the first servo motor 8 is started to drive the first bevel gear 9 to rotate. Since the first bevel gear 9 and the second bevel gear 10 are meshed, the second bevel gear 10 drives the threaded rod 11 to rotate, which in turn drives the threaded sleeve 12 to move. Then, under the limitation of the limiting groove 14 and the limiting block 15, the threaded sleeve 12 drives the moving cavity 13 to move, which in turn drives... The positioning plate 5 moves downward, using the base 4 and the positioning plate 5 to clamp and fix the steel pipe. After grinding, the first servo motor 8 is started to reverse, driving the moving cavity 13 to move upward, which in turn drives the positioning plate 5 to move upward. At this time, the second servo motor 17 is started to reverse, driving the positioning plate 5 to rotate, so that the positioning plate 5 and the base 4 are completely misaligned in the vertical direction. At this time, the steel pipe can be lifted for convenient unloading. The positioning plate 5 can be driven to rotate and descend, making it more convenient and faster for the base 4 and the positioning plate 5 to clamp the steel pipe, thus greatly improving the convenience of the device in use.

[0021] The limiting structure includes a limiting groove 14 and a limiting block 15. The limiting groove 14 is opened on both sides inside the mounting cavity 7. The limiting block 15 is provided inside the limiting groove 14. One end of the limiting block 15 is connected to the outside of the moving cavity 13. In use, the mutual cooperation between the limiting groove 14 and the limiting block 15 can limit the movement of the moving cavity 13, making the moving cavity 13 more stable when moving.

[0022] Anti-slip particles 6 are installed on the inner side of both the base 4 and the positioning plate 5. Multiple anti-slip particles 6 are set inside the base 4 and the positioning plate 5. The design of multiple anti-slip particles 6 makes the steel pipe more stable and less prone to slipping when beveling and grinding.

[0023] The adjustment mechanism includes an electric telescopic rod 20, a guide rod 21, and a guide sleeve 22. The electric telescopic rod 20 is installed on the top of the base plate 1, and its top end is connected to the bottom end of the beveling machine body 2. The guide rod 21 is installed at the rear end of the top of the base plate 1, and the guide sleeve 22 is provided on the outer side wall of the guide rod 21. One end of the guide sleeve 22 is connected to one end of the beveling machine body 2. In use, the electric telescopic rod 20 is activated. Under the guidance of the guide rod 21 and the guide sleeve 22, the electric telescopic rod 20 is used to adjust the beveling machine body 2 and the grinding tool 3 to an appropriate position, so that the center of the grinding tool 3 and the center of the steel pipe are on the same straight line. This allows the beveling machine body 2 and the grinding tool 3 to be adjusted according to the actual condition of the steel pipe during use, and to process different types of steel pipes, thereby greatly improving the versatility of the device in use.

[0024] The cross-section of the guide rod 21 is smaller than that of the guide sleeve 22. The guide rod 21 and the guide sleeve 22 form a sliding structure. In use, the mutual cooperation between the guide rod 21 and the guide sleeve 22 can guide the beveling machine body 2 when it moves, making the beveling machine body 2 more stable when it moves.

[0025] Working principle: The operator first starts the electric telescopic rod 20. Guided by the guide rod 21 and guide sleeve 22, the electric telescopic rod 20 is used to adjust the beveling machine body 2 and the grinding tool 3 to the appropriate positions, so that the center of the grinding tool 3 and the center of the steel pipe are on the same straight line. Then, the steel pipe is placed above the base 4, with one end of the steel pipe extending to the inside of the grinding tool 3. Then, the second servo motor 17 is started to drive the worm gear 18 to rotate. Since the worm gear 18 and the worm wheel 19 are meshed, the worm wheel 19 drives the positioning plate 5 to rotate, so that the positioning plate 5 is located directly above the base 4. Then, the first servo motor 8 is started to drive the first bevel gear 9 to rotate. Since the first bevel gear 9 and the second bevel gear 10 are meshed, the second bevel gear 10 drives the threaded rod 11 to rotate. The rotation of the screw thread sleeve 12 causes it to move, and under the limitation of the limiting groove 14 and the limiting block 15, the screw thread sleeve 12 drives the moving cavity 13 to move, which in turn drives the positioning plate 5 to move downward. The base 4 and the positioning plate 5 are used to clamp and fix the steel pipe. The use of anti-slip particles 6 makes the steel pipe more stable and less prone to slipping when clamped. At this time, the main body 2 of the beveling machine is started, which drives the grinding tool 3 to rotate. The grinding tool 3 is used to automatically grind the bevel of the steel pipe. After grinding, the first servo motor 8 is started to reverse, which drives the moving cavity 13 to move upward, and then drives the positioning plate 5 to move upward. At this time, the second servo motor 17 is started to reverse, which drives the positioning plate 5 to rotate, so that the positioning plate 5 and the base 4 are completely misaligned in the vertical direction. At this time, the steel pipe can be lifted and easily unloaded.
