[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 A deburring device for metal tubes includes a frame 2, a disc 4 rotatably connected to the frame 2, and a rotary motor 3 fixed to the frame 2 and drivenly connected to the disc 4. At least two deburring brush rods 18 are eccentrically mounted on the disc 4. The two deburring brush rods 18 are arranged in a V-shape, and one deburring brush rod 18 is located outside the other deburring brush rod 18 along the radial direction of the disc 4. The area between the adjacent sides of the two deburring brush rods 18 is the deburring area of ​​the metal tube 1. One end of the deburring brush rod 18 is rotatably connected to the disc 4, and the two are elastically arranged. The free end of the deburring brush rod 18 can elastically approach or elastically move away from the axis of the disc 4.

[0025] refer to Figure 1 When this device is working, the rotary motor 3 drives the disc 4 to rotate, which in turn drives the deburring brush rods 18 on the disc 4 to rotate around the axis of the disc 4. When the two V-shaped deburring brush rods 18 rotate around the axis of the disc 4, a dynamic annular area is formed in the deburring area. The metal tube 1 is inserted into the dynamic annular area along the axis of the disc 4. Since one end of the deburring brush rod 18 is rotatably connected to the disc 4 and the two are elastically set, the free end of the deburring brush rod 18 can elastically approach or elastically move away from the axis of the disc 4. Therefore, the space of this dynamic annular area can adapt to metal tubes 1 with different wall thicknesses and diameters without manual adjustment. It is simple and convenient to use and has a wider range of applications.

[0026] refer to Figure 1 The brush rod 18 on the inner wall of the metal tube 1 is defined as the inner ring brush rod 9, and the brush rod 18 on the outer wall of the metal tube 1 is defined as the outer ring brush rod 6. One end of the inner ring brush rod 9 is rotatably connected to the disk 4 through the second hinge 11. A second thrust spring 10 is installed between the side of the inner ring brush rod 9 away from the deburring area and the disk 4. One end of the outer ring brush rod 6 is rotatably connected to the disk 4 through the first hinge 8. A first thrust spring 7 is installed between the side of the outer ring brush rod 6 away from the deburring area and the disk 4.

[0027] refer to Figure 1 The second thrust spring 10 generates an elastic thrust on the inner ring brush rod 9 in a direction away from the axis of the disk 4, and the first thrust spring 7 generates an elastic thrust on the outer ring brush rod 6 in a direction closer to the axis of the disk 4.

[0028] As a method of deburring, a scraper is provided on the side of the deburring area of ​​the deburring brush 18, and the burrs at the end of the metal tube 1 are removed by the scraper;

[0029] As a method of deburring, the deburring brush 18 is provided with bristles 14 on the side near the deburring area, and the bristles 14 are used to remove the burrs at the end of the metal tube 1. The bristles 14 can be made of steel wire.

[0030] Since the bristles are easily worn consumables, the bristle brush handle 18 includes a bottom support 12 and a bristle base 13 for easy replacement. The bottom support 12 is connected to the disc 4 via a hinge. The bristle base 13 and the bottom support 12 are detachable and can be assembled separately. The bristles 14 are provided on the bristle base 13. When the bristles 14 are worn out, the bottom support 12 with the bristles 14 can be replaced.

[0031] The brush base 13 and the bottom support 12 can be connected by Velcro.

[0032] Or refer to Figure 3 , Figure 4 The burr brush rod 18 includes two C-shaped clamping members 15. The bottom support 12 and the bristle base 13 are clamped between the two horizontal strips of the C-shaped clamping members 15, and the bottom support 12 and the bristle base 13 are clamped together by the C-shaped clamping members 15.

[0033] To improve clamping stability, at least one crossbar of the C-type clamping member 15 has an inwardly protruding strip 16 that abuts against the bristle base 13.

[0034] To facilitate the clamping of the C-type clamping piece 15 onto the bottom support base 12 and the bristle base 13, one end of the protruding strip 16 is provided with a beveled surface 17.

[0035] refer to Figure 1 Each pair of two V-shaped burr brush rods 18 is defined as a pair. At least two pairs of burr brush rods 18 are eccentrically mounted on the disc 4. Using two pairs of burr brush rods 18 makes it easier for the metal tube 1 to be inserted into the deburring area and be concentric with the disc.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
