[0001] This utility model relates to the field of steel pipe inner wall processing technology, and in particular to a burr removal device for the inner wall of steel pipes. Background Technology

[0002] Steel pipes are steel materials with hollow cross sections, whose length is much greater than their diameter or circumference. During the processing of steel pipes, metal burrs are easily generated on their inner walls, requiring the use of burr removal equipment to clean the burrs on the inner walls.

[0003] For example, CN214237488U discloses a burr removal device for the inner wall of a steel pipe, including a support, a brush roller, a screw rod, and a slide. The support is a frame structure with open ends, and four feet are symmetrically installed on both sides of the support. The brush roller is set inside the support, and one end of the brush roller is connected to one side of the inner wall of the support. The screw rod is set below the brush roller, and both ends of the screw rod are connected to the inner walls of both sides of the support. Both ends of the slide are connected to two slide rails, and the two slide rails are installed on the other two sides of the inner wall of the support.

[0004] In the existing technology, since steel pipes come in different sizes and have different inner wall diameters, when cleaning burrs on the inner wall of steel pipes, it is necessary to frequently change rollers that are adapted to the inner wall size of the steel pipes. It is not possible to directly adjust the position of the rollers to adapt to the cleaning of burrs on different steel pipes. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that the position of the roller cannot be directly adjusted to remove burrs from the inner wall of steel pipes of different sizes, and to propose a burr removal device for the inner wall of steel pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a burr removal device for the inner wall of steel pipes, comprising a processing table, a positioning transmission mechanism installed on one side of the processing table, and a burr removal mechanism installed on the other side of the processing table. The burr removal mechanism includes two grinding rollers, one end of each grinding roller is fixedly connected to a connecting block, one side of each connecting block is rotatably connected to a rotating rod, one end of each rotating rod is rotatably connected to a moving block, one end of each moving block is fixedly connected to a first electric push rod, one side of each first electric push rod is fixedly connected to a fixing plate, and one end of each fixing plate is fixedly connected to one side of the processing table.

[0007] Preferably, guide rods are fixedly connected to both sides of the fixed plate, and the outer side of the guide rods is slidably connected to the moving block.

[0008] Preferably, the positioning transmission mechanism includes a mounting base and two rotating sleeves, with a second electric push rod fixedly connected to the inner side of the two rotating sleeves, and a clamping plate fixedly connected to one end of the second electric push rod.

[0009] Preferably, a telescopic rod is fixedly connected to one side of the clamping plate, and one end of the telescopic rod is fixedly connected to the inner ring surface of the rotating sleeve plate.

[0010] Preferably, a sliding strip is fixedly connected to the outer surface of the rotating sleeve plate, and a support frame is slidably connected to the outside of the sliding strip. One side of the support frame is fixedly connected to one side of the processing table.

[0011] Preferably, a connecting plate is fixedly connected to one side of the rotating sleeve, and an external gear ring is fixedly connected to one end of the connecting plate.

[0012] Preferably, a transmission gear is engaged on one side of the external gear ring, a drive motor is fixedly connected to the middle of the transmission gear, one side of the drive motor is fixedly connected to one side of the mounting base, and one end of the mounting base is fixedly connected to one side of one of the support frames.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the first electric push rod drives the connected moving block to move, and the other moving block moves synchronously, so that the two connecting blocks move, thereby adjusting the distance between the two grinding rollers. The outer walls of the two grinding rollers are adjusted to fit with the inner wall of the steel pipe to be processed, and the burrs on the inner wall of the steel pipe are cleaned. The position of the grinding rollers can be directly adjusted to clean the burrs on steel pipes of different sizes, reducing the number of times the grinding rollers need to be replaced.

[0015] 2. In this utility model, the second electric push rod drives the clamping plate to move, clamping and fixing the outer wall of the steel pipe. The clamping plate is provided with an anti-slip strip on the side where it is fixed to the steel pipe, which improves the fixing effect of the steel pipe and prevents the steel pipe from moving during the removal of burrs on the inner wall, thus affecting the burr removal effect. In addition, the drive motor drives the transmission gear to rotate, and the rotating sleeve plate rotates accordingly, causing the steel pipe to rotate, so that there is relative movement between the steel pipe and the grinding roller, which improves the efficiency of burr removal on the inner wall of the steel pipe.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a burr removal device for the inner wall of steel pipes, including a processing table 1. A positioning transmission mechanism 3 is installed on one side of the processing table 1, and a burr removal mechanism 2 is installed on the other side of the processing table 1. The burr removal mechanism 2 includes two grinding rollers 21. A connecting block 27 is fixedly connected to one end of the two grinding rollers 21. A rotating rod 26 is rotatably connected to one side of the connecting block 27. A moving block 25 is rotatably connected to one end of the rotating rod 26. A first electric push rod 22 is fixedly connected to one end of one of the moving blocks 25. A fixing plate 23 is fixedly connected to one side of the first electric push rod 22. One end of the fixing plate 23 is fixedly connected to one side of the processing table 1. Guide rods 24 are fixedly connected to both sides of the fixing plate 23. The outer side of the guide rods 24 is slidably connected to the moving block 25.

[0024] The steel pipe is passed through the positioning transmission mechanism 3 and fitted onto the outside of the grinding roller 21. The first electric push rod 22 drives the moving block 25 connected to it to move. The rotating rod 26 connected to one side of the moving block 25 rotates, driving the other moving block 25 to move synchronously. The moving block 25 slides outside the guide rod 24, and can be fixed to make the moving block 25 move linearly, so that the two connecting blocks 27 move, thereby adjusting the distance between the two grinding rollers 21, so that the outer wall of the two grinding rollers 21 fits against the inner wall of the steel pipe to be processed, and the burrs on the inner wall of the steel pipe are removed. The first electric push rod 22 is fixed on one side of the fixed plate 23, and the two moving blocks 25 move the same distance to both sides, so that the center point of the distance adjustment of the two grinding rollers 21 remains unchanged, preventing the deburring position of the steel pipe from shifting.

[0025] Example 2: Figure 1 , Figure 2 and Figure 4 As shown, the positioning transmission mechanism 3 includes a mounting base 31 and two rotating sleeve plates 33. A second electric push rod 36 is fixedly connected to the inner side of the two rotating sleeve plates 33, and a clamping plate 38 is fixedly connected to one end of the second electric push rod 36. A telescopic rod 37 is fixedly connected to one side of the clamping plate 38, and one end of the telescopic rod 37 is fixedly connected to the inner ring surface of the rotating sleeve plate 33. A sliding strip 39 is fixedly connected to the outer surface of the rotating sleeve plate 33, and a support frame 35 is slidably connected to the outside of the sliding strip 39. One side of the support frame 35 is fixedly connected to one side of the processing table 1. A connecting plate 311 is fixedly connected to one side of the rotating sleeve plate 33, and an external gear ring 310 is fixedly connected to one end of the connecting plate 311. A transmission gear 34 meshes with one side of the external gear ring 310, and a drive motor 32 is fixedly connected to the middle of the transmission gear 34. One side of the drive motor 32 is fixedly connected to one side of the mounting base 31, and one end of the mounting base 31 is fixedly connected to one side of one of the support frames 35.

[0026] By passing the steel pipe through two rotating sleeve plates 33, the second electric push rod 36 pushes the clamping plate 38 to move, and the telescopic rod 37 extends to facilitate the linear movement of the clamping plate 38. The movement of the clamping plate 38 clamps and fixes the outer wall of the steel pipe. An anti-slip strip is provided on the side of the clamping plate 38 that is fixed to the steel pipe to improve the fixing effect of the steel pipe and prevent the steel pipe from moving during the removal of burrs on the inner wall, which would affect the burr removal effect. The drive motor 32 drives the transmission gear 34 to rotate, and the meshing external gear ring 310 rotates, which in turn drives the connecting plate 311 and the rotating sleeve plate 33 to move in sequence. The sliding strip 39 on the outer surface of the rotating sleeve plate 33 slides on the inner side of the support frame 35 to fix the rotation position of the rotating sleeve plate 33. The rotation of the rotating sleeve plate 33 drives the steel pipe clamped and fixed by the clamping plate 38 to rotate, and the relative movement between the steel pipe and the grinding roller 21 facilitates the removal of burrs on the inner wall of the steel pipe.

[0027] The method of use and working principle of this device: By passing the steel pipe through two rotating sleeve plates 33, the second electric push rod 36 drives the clamping plate 38 to move, clamping and fixing the outer wall of the steel pipe. The steel pipe is then passed through the positioning transmission mechanism 3 and placed outside the grinding roller 21. The first electric push rod 22 drives the moving block 25 connected to it to move. The rotating rod 26 connected to one side of the moving block 25 rotates, driving the other moving block 25 to move synchronously. The moving block 25 slides outside the guide rod 24, which can fix the moving block 25 to make linear motion, causing the two connecting blocks 27 to move, thereby adjusting the distance between the two grinding rollers 21, so that the outer wall of the two grinding rollers 21 fits against the inner wall of the steel pipe to be processed. The drive motor 32 drives the transmission gear 34 to rotate, which in turn drives the outer gear ring 310, the connecting plate 311 and the rotating sleeve plate 33 to move in sequence. The rotation of the rotating sleeve plate 33 drives the steel pipe clamped and fixed by the clamping plate 38 to rotate, thus cleaning the burrs on the inner wall of the steel pipe.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
