[0037] In short, the seamless steel pipe oxidation grinding equipment has become an ideal equipment in the field of steel pipe grinding due to its precise structure and excellent performance. It not only improves production efficiency, but also ensures product quality and meets the high standards of modern industrial production.

[0038] Further, according to some embodiments of the utility model, the four corners of the bottom of the base plate 1 are respectively fixedly connected with support rods 17, and the bottom of the support rods 17 is fixedly connected to the support feet 18. The design of the base plate 1 has a unique structure. The four corners of the bottom of the base plate 1 are carefully designed for the fixed connection of the support rods 17. These support rods 17, as an important guarantee for the stability of the entire device, are closely connected to the base plate 1 at their bottom to ensure that the device can work stably and reliably during use.

[0039] In order to further improve the stability and service life of the equipment, the designer also specially processed the bottom of the support rod 17 to form a firm connection with the support foot 18. This design not only makes the equipment more stable when bearing weight and external force, but also can effectively reduce the damage caused by vibration and impact, thereby extending the service life of the equipment.

[0040] Further, according to some embodiments of the utility model, the top of the positioning plate 9 is equipped with a limiting strip 19, and the bottom of the limiting strip 19 passes through the positioning plate 9 and extends into the interior thereof. The top of this positioning plate 9 is uniquely designed, and the limiting strip 19 is cleverly integrated. The bottom of the limiting strip 19 passes through the positioning plate 9 and extends into the interior thereof. This design concept not only improves the practicality of the product, but also enhances its stability.

[0041] First, this design allows the positioning plate 9 to better control the position of the object during use, preventing the object from accidentally sliding during movement. The limit strip 19 extends into the interior of the positioning plate 9, which can effectively fix the object and ensure that it remains stable in the required position. This is particularly important for scenarios where the position of the object needs to be precisely controlled, such as in the fields of electronic equipment manufacturing, precision instrument operation, etc.

[0042] Secondly, this design enhances the structural stability of the positioning plate 9. The limiting strip 19 passes through the positioning plate 9 and extends to the inside, forming a strong structure, so that the positioning plate 9 can remain stable and not easily deformed when subjected to a certain weight and external force. This provides users with higher safety during use and avoids damage to items caused by damage or deformation of the positioning plate 9.

[0043] Further, according to some embodiments of the present invention, the top and bottom of the inner side of the sliding plate 15 are provided with a return spring 20, and the inner side of the return spring 20 is tightly fixed to the connecting rod 12. In the design of the sliding plate 15, the top and bottom of the inner side are equipped with a return spring 20, which is a key component. The function of the return spring 20 is to quickly restore the connecting rod 12 to its initial position after performing the corresponding action, so as to prepare for the next action.

[0044] The inner side of the reset spring 20 is tightly fixed to the connecting rod 12, which is a precise fit. This fixing method can ensure that the spring can effectively bring the connecting rod 12 back to the initial position quickly when performing the reset task, greatly improving the working efficiency of the equipment. At the same time, this tight fixing method also helps to increase the service life of the spring, so that it can maintain good performance during long-term work.

[0045] Further, according to some embodiments of the present invention, the top and bottom of the sliding plate 15 are respectively fixedly equipped with sliders 21, the top and bottom of the inner wall of the connecting rod 12 are provided with sliding grooves 22, and the sliding grooves 22 are slidably connected to the sliders 21.

[0046] In the design of the sliding plate 15, the top and bottom thereof are respectively fixedly equipped with sliders 21, which is to achieve stability and smoothness during the movement of the sliding plate 15. The existence of the sliders 21 enables the sliding plate 15 to slide smoothly on the fixed track, thereby improving the use efficiency and life of the entire device.

[0047] The top slider 21 and the bottom slider 21 of the sliding plate 15 are connected by the connecting rod 12. This design enables the sliding plate 15 to better adapt to various complex environments during movement. The top and bottom of the inner wall of the connecting rod 12 are provided with sliding grooves 22, so that the slider 21 can slide freely inside the connecting rod 12. This design not only improves the flexibility of the sliding plate 15, but also makes it more stable during movement.

[0048] In addition, the sliding connection between the chute 22 and the slider 21 is also very important. It enables the slider 21 to slide accurately in the chute 22, thereby ensuring the accuracy and speed of the sliding plate 15 during movement.

[0049] Further, according to some embodiments of the utility model, the front and bottom of the column 6 are fixedly connected with a fixing block 7, and the bottom of the fixing block 7 is stably connected to the rotating plate 4. Its main feature is that the front and bottom of the column 6 are fixedly connected with the fixing blocks 7, and the bottoms of these fixing blocks 7 are stably connected to the rotating plate 4. This design has excellent rotation performance while maintaining structural stability. Below we will analyze the working principle and advantages of this design in detail from each part.

[0050] First, let's take a closer look at column 6. Column 6 is the core component of the entire structure, and it undertakes the task of support and stability. On its front and bottom, we set fixed blocks 7, which is a carefully designed strategy to improve the stability of the entire structure.

[0051] Next, let's look at the function of the fixing block 7. The fixing block 7 is stably connected to the rotating plate 4 through its bottom, so that the column 6 can effectively disperse the force when it is subjected to pressure or impact, ensuring the stability of the entire structure. This design allows the column 6 to maintain stable performance when dealing with various complex environments.

[0052] In addition, this design also has good rotation performance. Since the connection between the fixed block 7 and the rotating plate 4 is stable, the column 6 can easily complete the corresponding action when rotation is required. This makes the entire structure meet the stability requirements while having excellent flexibility.

[0053] It is worth mentioning that this design is also highly convenient in the manufacturing and installation process. The connection mode of the fixed block 7, the column 6 and the rotating plate 4 is simple and easy to operate, which greatly improves the production efficiency.

[0054] The present embodiment is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiment. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the present purpose.
