Description

Technical Field

[0001] The utility model relates to the technical field of tube blank processing, in particular to a device for repairing inner and outer walls of a tube blank. Background Art

[0002] Pipe blanks, as a professional term for initially formed tubular materials in the field of steel processing, refer to raw materials that have undergone preliminary processing but have not yet completed the final forming process. After these pipe blanks are produced and leave the production line, it is inevitable that cracks and other defects will occasionally appear on their inner and outer surfaces. If these cracks exist on the inner wall of the pipe blank, the operator must grind it. The purpose of this process is to remove any imperfections on the surface of the pipe blank and ensure the integrity of the quality of the pipe in subsequent processing.

[0003] However, since the current grinding is mainly done manually, assisted by small machines such as grinding wheels, the overall processing efficiency is relatively low and is not suitable for mass production within the factory.

[0004] Therefore, a tube blank inner and outer wall repair device is proposed to solve or alleviate the above problems. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a device for repairing the inner and outer walls of a tube blank.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The invention discloses a device for repairing inner and outer walls of a tube blank, comprising a positioning assembly for positioning the tube blank, a rotatably arranged active disk, a rotatably arranged driven disk, and a grinding belt sleeved on the active disk, the driven disk and the outer side of the tube blank, wherein the active disk and the driven disk are displaceably arranged in the same vertical direction, and the grinding belt has elastic deformation performance.

[0008] Preferably, the positioning assembly includes a horizontally arranged track, a slide seat slidably connected to the track, a mounting shell fixedly connected to the slide seat, and an elastic column sleeve fixedly connected to the mounting shell and protrudingly arranged, and the slide seat is fixedly connected to the track by bolts.

[0009] Preferably, the elastic column sleeve is in a truncated cone shape.

[0010] Preferably, it also includes a connecting frame 1, and the positioning assembly is fixedly connected to the connecting frame 1.

[0011] Preferably, it further comprises a second connecting frame, on which an electric slide rail assembly is arranged, the driven disk is arranged on the movable end of the electric slide rail assembly, and the active disk is detachably connected to the electric slide rail assembly.

[0012] Preferably, the electric slide rail assembly includes a slide rail, a sliding seat slidably connected thereon, a lead screw rotatably connected thereto, and a servo motor fixedly connected to one end of the slide rail, the output shaft of the servo motor is coaxially connected to the lead screw, and the sliding seat is threadedly connected to the lead screw, and the driven disk is rotatably connected to the sliding seat via an upper rotating shaft.

[0013] Preferably, a fixing seat is detachably connected to the slide rail, a lower rotating shaft is rotatably connected to the fixing seat, and the active disk is fixedly connected to the lower rotating shaft.

[0014] Preferably, it also includes a driving motor, a driving wheel fixedly connected to the output shaft of the driving motor, a driven wheel fixedly connected to the lower rotating shaft, and a transmission belt that transmits transmission connection between the driving wheel and the driven wheel.

[0015] The utility model has the following beneficial effects:

[0016] When the utility model is applied, when the staff is faced with the need to perform grinding and repair work on the outer wall defects of the tube blank, the operator first needs to fix the tube blank on the positioning assembly. After that, the operator needs to place the grinding belt on the surface of the tube blank, as well as the linked active disk and driven disk, rotate the active disk, and then drive the entire grinding belt to start rotating. This rotational action enables the grinding belt to generate efficient and uniform friction on the part of the tube blank to be processed, so as to remove those surface cracks. If the damaged area of ​​the tube blank is small, the active disk and the driven disk will adjust the distance between them accordingly, so that the shape of the grinding belt will produce corresponding deformation to adapt to the requirements of different shapes of the tube blank, and at the same time reduce the contact area between the grinding belt and the tube blank to achieve a more precise grinding effect. On the contrary, if the area to be polished is large, the active disk and the driven disk are close to each other to adapt to a wider grinding area, so that the staff can process the tube blank in a continuous and automated process, which greatly improves production efficiency and ensures the quality and uniformity of grinding.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Tube inner and outer wall repair device, such as Figure 1 and 4 As shown, it includes a positioning assembly for positioning the steel pipe, a rotatable active disk 16, a rotatable driven disk 18, and a grinding belt 21 sleeved on the active disk 16, the driven disk 18 and the outer side of the tube blank. The grinding belt 21 has elastic deformation performance. Specifically, the grinding belt 21 is a sanding belt.

[0024] Also includes a connecting frame 1, such as Figure 3 As shown, the positioning assembly is fixedly connected to the connecting frame 1, and the positioning assembly includes a track 2 horizontally arranged and fixedly connected to the connecting frame 1, a slide 3 slidably connected to the track 2, a mounting shell 4 fixedly connected to the slide 3, and an elastic column sleeve 5 fixedly connected to the mounting shell 4 and protrudingly arranged. The slide 3 is fixedly connected to the track 2 by bolts, and the elastic column sleeve 5 is truncated cone-shaped.

[0025] It also includes a connecting frame 2 6, and the driving disk 16 and the driven disk 18 are arranged to be displaceable in the same vertical direction. The specific implementation method is as follows: Figure 2 As shown, an electric slide rail assembly is arranged on the connecting frame, a driven disk 18 is arranged on the movable end of the electric slide rail assembly, and a driving disk 16 is detachably connected to the electric slide rail assembly. The electric slide rail assembly includes a slide rail 7, a sliding seat 10 slidably connected thereon, a lead screw rotatably connected therein, and a servo motor 8 fixedly connected to one end of the slide rail 7, the output shaft of the servo motor 8 is coaxially connected to the lead screw, and the sliding seat 10 is threadedly connected to the lead screw, the driven disk 18 is rotatably connected to the sliding seat 10 through an upper rotating shaft 17, a fixed seat 9 is detachably connected to the slide rail 7 through bolts, a lower rotating shaft 14 is rotatably connected to the fixed seat 9, and the driving disk 16 is fixedly connected to the lower rotating shaft 14, and further includes a driving motor 11, a driving wheel 12 fixedly connected to the output shaft of the driving motor 11, a driven wheel 15 fixedly connected to the lower rotating shaft 14, and a transmission belt 13 for transmission connection between the driving wheel 12 and the driven wheel 15.

[0026] When people need to use the tube blank inner and outer wall repair device to grind the defects of the outer wall of the tube blank, they only need to lift the tube blank and put it on the outside of the positioning component. The slide 3 in the positioning component adjusts the spacing according to the inner diameter of the tube blank, and then fixes the slide 3 on the track 2 by bolts. At the same time, the elastic column sleeve 5 made of rubber material is made to contact with the inner wall of the tube blank. Since the elastic column sleeve 5 is truncated cone-shaped, as long as the smallest end of the elastic column sleeve 5 can contact with the inner wall of the tube blank, the largest end of the elastic column sleeve 5 will exert an outward expansion force on the inner wall of the tube blank, thereby completing the positioning of the tube blank.

[0027] Next, the grinding belt 21 is put on the active disk 16, the driven disk 18 and the outside of the tube blank, and then the contact area between the grinding belt 21 and the tube blank is adjusted according to the size of the defect on the outside of the tube blank. If the area on the tube blank that needs to be polished is small, the active disk 16 and the driven disk 18 are pulled apart to deform the grinding belt 21 to adapt to the shapes of the three and reduce the contact area with the tube blank. When the area on the tube blank that needs to be polished is large, the active disk 16 and the driven disk 18 are pulled closer to each other to deform the grinding belt 21 to adapt to the shapes of the three and increase the contact area with the tube blank. In this way, the surface defects of the tube blank can be polished.

[0028] When the position to be polished needs to be adjusted, the connection frame 1 only needs to be modulated and adjusted to make the polishing belt 21 fit at different positions on the surface of the tube blank, so that the surface of the tube blank can be easily and quickly processed.

[0029] When it is necessary to process the inside of the tube blank, the tube blank is positioned and lifted through the positioning component, and then the grinding wheel is manually extended into the inner wall of the tube blank for processing. At the same time, the processing of the inner and outer walls can be carried out at the same time, which greatly improves the processing efficiency.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
