[0026] A processing device for coating treatment of the inner wall surface of a metal tube includes: a base plate 1 and a metal tube 2. The base plate 1 is sequentially provided with a positioning component 3, a support part 4, a clamping part 5 and a moving slide 6. The metal tube 2 is placed on the support part 4 and corresponds to the height of the positioning component 3. The clamping part 5 is located above the metal tube 2 and the support part 4. A grinding part 7 is slidably connected in the moving slide 6. The grinding part 7 and the positioning component 3 are respectively located at both ends of the metal tube 2.

[0027] First, adjust the support rod 311 in the positioning component 3 to open it up to achieve the purpose of positioning the metal tube 2. Then, raise the height of the support part 4 to lift the metal tube 2 from below. Next, lower the height of the clamping part 5 to clamp the metal tube 2 from above and drive it to rotate. Finally, adjust the position of the grinding part 7 on the moving slide 6 so that the grinding rod 77 extends into the metal tube 2 to grind the inner wall surface.

[0028] The positioning component 3 includes a first support plate 31, a first movable seat 37, and a first connecting rod 310. A fixed seat 32 is fixedly connected to the first support plate 31, and a mounting plate 33 is fixedly connected to the fixed seat 32. A screw 34 is rotatably connected to the mounting plate 33, and a guide rod 35 is fixedly connected to the mounting plate 33. A turntable 36 for adjusting the screw 34 is fixedly connected to the end of the screw 34. The first movable seat 37 is sleeved on the screw 34 and the guide rod 35. The mounting plate 33 has evenly distributed expansion slots 38. A second movable seat 39 is slidably connected in the expansion slots 38.

A support rod 311 for positioning the metal tube 2 is fixedly connected to the second movable seat 39.

[0029] By rotating the turntable 36, the screw 34 is driven to rotate, causing the first movable seat 37 to move on the screw 34 and the guide rod 35. Then, the first connecting rod 310 pushes the second movable seat 39 to slide in the unfolding groove 38, thereby driving the support rod 311 to extend and retract radially. This allows for precise positioning of metal tubes 2 with different inner diameters, increasing the applicability of the device.

[0030] The support part 4 includes a base 41 and a bearing plate 47. A first drive motor 42 and a guide groove 43 are provided on the base 41.

The lower part of the bearing plate 47 is rotatably connected to the lifting frame 46.

[0031] The first drive motor 42 drives the bidirectional lead screw 44 to rotate, causing the third moving seat 45 to slide in the guide groove 43. The height of the bearing plate 47 is adjusted by the lifting frame 46, and the height of the support wheel assembly 48 can be adjusted according to the diameter of the metal tube 2, so that the metal tube 2 is placed more stably and provides stable support for subsequent processing.

[0032] The upper two sides of the bearing plate 47 are provided with support wheel sets 48, which are used to support the metal tube 2 from below.

[0033] The support wheel sets 48 on both sides of the upper part of the support plate 47 support the metal tube 2 from below, reducing the contact area between the metal tube 2 and the support plate 47 and reducing friction. The support wheel sets 48 can rotate synchronously with the rotation of the metal tube 2, ensuring smooth rotation of the metal tube 2.

[0034] The pressing part 5 includes a second support plate 51, and a lifting push rod 52 is fixedly connected above the second support plate 51. A roller 53 is provided at the lower end of the lifting push rod 52, and a second drive motor 54 is provided on the side of the roller 53.

[0035] The lifting push rod 52 of the clamping part 5 can adjust the height of the roller 53 so that it clamps the metal tube 2. The second drive motor 54 drives the roller 53 to rotate, thereby driving the metal tube 2 to rotate.

[0036] The grinding section 7 includes a third support plate 71, a grinding rod 77, and a second connecting rod 78. A first fixed rod 72 and a telescopic push rod 75 are fixedly connected to the third support plate 71. A sliding groove 73 is provided on the first fixed rod 72.

The other end of the telescopic sleeve 79 is fixedly connected to the grinding rod 77.

[0037] The telescopic push rod 75 pushes the collar 74 to slide along the slide groove 73, and drives the grinding rod 77 to extend and retract radially through the second connecting rod 78. The position of the grinding rod 77 can be adjusted to adapt to the grinding of the inner wall surface of metal tubes 2 of different diameters. The telescopic sleeve 79 provides support and guidance for the grinding rod 77, making the grinding rod 77 more stable and reliable during the grinding process.

[0038] The working principle of the processing device for coating the inner wall surface of metal pipes provided by this utility model is as follows:

[0039] First, adjust the support rod 311 in the positioning component 3 to open it up to achieve the purpose of positioning the metal tube 2. Then, raise the height of the support part 4 to lift the metal tube 2 from below. Next, lower the height of the clamping part 5 to clamp the metal tube 2 from above and drive it to rotate. Finally, adjust the position of the grinding part 7 on the moving slide 6 so that the grinding rod 77 extends into the metal tube 2 to grind the inner wall surface.

[0040] Compared with related technologies, the processing device for coating treatment of the inner wall surface of metal pipes provided by this utility model has the following beneficial effects:

[0041] The support rod 311 in the positioning component 3 is adjusted by the turntable 36, screw 34 and other components to accurately position metal tubes 2 with different inner diameters; both the support part 4 and the clamping part 5 can be height adjusted, which reduces friction with the metal tube 2 compared with the conventional placement base and can drive the metal tube 2 to rotate, thus facilitating the grinding work; the grinding rod 77 in the grinding part 7 is adjusted in radial position by components such as the telescopic push rod 75 and telescopic sleeve 79 to adapt to the grinding of the inner wall of different tube diameters.
