Description

Technical Field

[0001] This utility model belongs to the field of stainless steel pipe processing technology, specifically relating to an adaptive adjustment grinding device for the inner wall of stainless steel pipes. Background Technology

[0002] Stainless steel pipe is a hollow, long, round steel material, mainly used in industrial pipelines for petroleum, chemical, medical, food, light industry, and machinery, as well as mechanical structural components. During the processing of stainless steel pipe, the inner wall of the stainless steel pipe needs to be polished, so polishing equipment is required.

[0003] Problems with existing technology: Existing grinding equipment generally does not allow for automatic adjustment of the grinding structure. When grinding different types of stainless steel pipes, different sizes of grinding heads need to be replaced, which makes the grinding process more complicated, increases the replacement time, and reduces the grinding efficiency of the inner wall of stainless steel pipes. Utility Model Content

[0004] The purpose of this invention is to provide a stainless steel pipe inner wall self-adjusting grinding device that can self-adjust the grinding structure, thereby accelerating the grinding efficiency for different types of stainless steel pipes.

[0005] The specific technical solution adopted by this utility model is as follows: A stainless steel pipe inner wall adaptive adjustment grinding device includes a grinding machine body. A rotating hole is opened on one side of the grinding machine body. A rotating sleeve is rotatably connected in the rotating hole. Grinding arc plates are symmetrically installed on the outer side of the rotating sleeve for grinding the inner wall of the stainless steel pipe. A motor is embedded in the inner wall of one side of the main body of the grinding machine. A gear is fixed to one end of the output shaft of the motor to drive the grinding structure for grinding.

[0006] A toothed ring is fixedly connected to the outer side of the rotating sleeve, and the outer side of the toothed ring is engaged with the outer wall of the gear.

[0007] The outer side of the rotating sleeve is provided with a protrusion, and the protrusion of the rotating sleeve is limited and connected to the inner wall of the rotating hole.

[0008] The outer side of the rotating sleeve is symmetrically provided with rotating grooves, and rotating arms are symmetrically rotatably connected in the rotating grooves. One side of the rotating arm is rotatably connected to the outer wall of the grinding arc plate by a hinge, and the other side of the rotating arm is rotatably connected to an adjusting plate by a hinge.

[0009] The adjusting plate has an adjusting hole, and an adjusting rod is sleeved in the adjusting hole. A connecting plate is fixed to the outer wall of both ends of the adjusting rod. A spring is fixed to one side of the outer wall of the connecting plate, and the other end of the spring is fixed to the outer wall of the adjusting plate.

[0010] The adjusting rod is fitted with a connecting sleeve, and a cylinder is embedded in one side of the grinding machine body, with the cylinder's telescopic rod rotatably connected to the outer wall of the connecting sleeve.

[0011] The technical effect achieved by this utility model is that the grinding arc plate on the rotating sleeve can be inserted into the inside of the stainless steel pipe. At this time, the driving structure drives the transmission structure to rotate the rotating sleeve quickly, and then the grinding arc plate grinds the inner wall of the stainless steel pipe, thus speeding up the grinding efficiency. When different types of steel pipes are used, the drive structure is activated to move the connecting sleeve. The connecting sleeve then acts on the adjusting rod, which in turn interacts with the adjusting plate. This causes the adjusting plate to act on the rotating arm, which in turn causes the grinding arc plate to rotate outward, thereby increasing the grinding range of the grinding arc plate and enhancing its adaptability.

[0012] This invention allows for automatic adjustment of the grinding structure. When grinding different types of stainless steel pipes, there is no need to change grinding heads of different sizes, thus simplifying the grinding process, reducing replacement time, and improving the grinding efficiency of the inner wall of stainless steel pipes.

It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0016] like Figure 1-2 As shown, a stainless steel pipe inner wall adaptive adjustment grinding device includes a grinding machine body 1. A rotating hole 2 is opened on one side of the grinding machine body 1. A rotating sleeve 7 is rotatably connected in the rotating hole 2. A grinding arc plate 16 is symmetrically installed on the outer side of the rotating sleeve 7 for grinding the inner wall of the stainless steel pipe. A motor 3 is embedded in the inner wall of one side of the main body 1 of the grinding machine. A gear 4 is fixed to one end of the output shaft of the motor 3 to drive the grinding structure for grinding.

[0017] A toothed ring 8 is fixedly connected to the outer side of the rotating sleeve 7, and the outer side of the toothed ring 8 is engaged with the outer wall of the gear 4.

[0018] The outer side of the rotating sleeve 7 is provided with a protrusion, and the protrusion of the rotating sleeve 7 is limited and connected to the inner wall of the rotating hole 2.

[0019] According to the above structure, the grinding arc plate 16 on the rotating sleeve 7 can be inserted into the stainless steel pipe. At this time, the driving structure drives the transmission structure to rotate the rotating sleeve 7 quickly, and then the grinding arc plate 16 grinds the inner wall of the stainless steel pipe, thus speeding up the grinding efficiency.

[0020] like Figure 2-3 As shown, the outer side of the rotating sleeve 7 is symmetrically provided with rotating grooves 9, and rotating arms 10 are symmetrically rotatably connected in the rotating grooves 9. One side of the rotating arm 10 is rotatably connected to the outer wall of the grinding arc plate 16 by a hinge, and the other side of the rotating arm 10 is rotatably connected to an adjusting plate 11 by a hinge.

[0021] An adjustment hole 12 is provided on the adjustment plate 11. An adjustment rod 13 is sleeved in the adjustment hole 12. A connecting plate 14 is fixed to the outer wall of both ends of the adjustment rod 13. A spring 15 is fixed to one side of the outer wall of the connecting plate 14, and the other end of the spring 15 is fixed to the outer wall of the adjustment plate 11.

[0022] The adjusting rod 13 is fitted with a connecting sleeve 6. A cylinder 5 is installed on one side of the grinding machine body 1, and the telescopic rod of the cylinder 5 is rotatably connected to the outer wall of the connecting sleeve 6.

[0023] According to the above structure, when different types of steel pipes are used, the drive structure is activated to move the connecting sleeve 6. Then, the connecting sleeve 6 acts on the adjusting rod 13. The adjusting rod 13 interacts with the adjusting plate 11, causing the adjusting plate 11 to act on the rotating arm 10. Then, the rotating arm 10 causes the grinding arc plate 16 to rotate outward, thereby increasing the grinding range of the grinding arc plate 16 and increasing the adaptability of grinding.

[0024] The working principle of this utility model is as follows: First, the grinding arc plate 16 on the rotating sleeve 7 is inserted into the stainless steel pipe. Then, the motor 3 is started to make the gear 4 rotate rapidly. Then, under the action of the gear ring 8, the limiting structure on the rotating sleeve 7 rotates rapidly along the rotating hole 2. Then, the grinding arc plate 16 on the rotating sleeve 7 grinds the inner wall of the stainless steel pipe. When encountering stainless steel pipes of different sizes, the cylinder 5 is started to move the connecting sleeve 6 along the rotating sleeve 7. The connecting sleeve 6 drives the adjusting rod 13 to move. Then, under the action of the adjusting hole 12, the adjusting plate 11 rotates along the rotating arm 10, and so on. The grinding arc plate 16 is driven to rotate along the rotating arm 10, thereby expanding the grinding range of the grinding arc plate 16. At this time, the motor 3 is started to make the gear 4 rotate rapidly. Then, under the action of the gear ring 8, the rotating sleeve 7 rotates rapidly along the rotating hole 2, and the connecting sleeve 6 rotates along the cylinder 5, which can meet the adjustment needs. Then, the grinding arc plate 16 is used to grind stainless steel pipes of different sizes. When the grinding is finished, the connecting sleeve 6 is reset when the cylinder 5 is started. Then, the connecting sleeve 6 drives the adjusting rod 13 to reset and move. At this time, under the action of the spring 15 on the connecting plate 14, the grinding arc plate 16 is reset to its original position.
