[0001] The utility model relates to the technical field of grinding devices, in particular to an online grinding tool for eliminating straightening marks on aluminum tubes. Background Art

[0002] Aluminum alloy is the most widely used type of non-ferrous metal structural material in current industrial applications. It is widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industries. In the production of aluminum alloy, straightening devices are required to obtain aluminum alloy profiles with composite application standards. Straightening machines are equipment for straightening metal profiles, bars, pipes, wires, etc.

[0003] When using a straightening machine to straighten aluminum alloy, it is necessary to apply pressure to the surface of the aluminum alloy pipe through the straightening roller to cause deformation. The straightening spiral mark will be left on the surface of the aluminum alloy, which will have an adverse effect on the appearance of the aluminum alloy product. At present, due to the lack of online grinding devices for straightening marks, manual grinding is usually used, which not only wastes manpower and increases labor costs, but also has low work efficiency and cannot guarantee the grinding effect of the product.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] In a specific embodiment of the present invention, an online grinding tool for eliminating straightening marks on aluminum tubes is used to grind the aluminum tubes straightened by the straightening machine 1, such as Figure 1 As shown, it includes a mounting frame 2 and a grinding assembly, the mounting frame 2 is installed on one side of the outlet end of the straightening machine 1, and the grinding assembly is installed on the mounting frame 2;

[0024] like Figure 2 、 Figure 3 As shown, the grinding assembly includes a rotating seat assembly 3, a power assembly 4 and two sanding belt assemblies 5. The rotating seat assembly 3 includes two seat rings 31 and a shaft ring 32 arranged between the two seat rings 31. The two seat rings 31 are installed in parallel on the mounting frame 2. A ball mounting seat 33 is provided between the two seat rings 31 and the shaft ring 32. A plurality of balls are provided in the ball mounting seat 33. The inner side of each of the two seat rings 31 is provided with an inner gear ring 35, and the outer side of the shaft ring is provided with an outer gear ring 34.

[0025] The power assembly 4 is disposed on one side of the mounting frame 2 and connected to the outer gear ring 34 . The two sanding belt assemblies 5 are both disposed inside the shaft ring 32 and connected to the inner gear ring 35 .

[0026] The power assembly 4 includes a drive motor 41 and a transmission gear 42. The transmission gear 42 is arranged on the outside of the shaft ring 32 and meshes with the outer gear ring 34. A synchronization rod 43 is passed through the transmission gear 42 and is rollingly mounted on the mounting frame 2 through the synchronization rod 43. A synchronization wheel 44 is provided at one end of the synchronization rod 43. A driving wheel 45 is provided at the output end of the drive motor 41. A belt 46 is connected between the driving wheel 45 and the synchronization wheel 44. The drive motor 41 is provided with a frequency converter for regulating the speed of the drive motor 41.

[0027] like Figure 4 As shown, any one of the abrasive belt assemblies 5 includes two mounting seats 51, an abrasive belt 52 and a planetary gear 53. The two mounting seats 51 are symmetrically connected to the inner wall of the shaft ring 32. Winding rollers 54 are rollingly provided on the two mounting seats 51. The abrasive belt 52 is wound around the two winding rollers 54. A planetary gear 53 is provided at one end of one of the winding rollers 54, and the planetary gear 53 is meshed with the inner gear ring 35.

[0028] The two abrasive belts 52 are arranged in parallel, and the two planetary gears 53 are respectively arranged on two winding rollers 54 that are far away from each other. The distance between the two abrasive belts 52 is smaller than the diameter of the straightened aluminum tube.

[0029] The use process of this utility model:

[0030] After being straightened by the straightening machine 1, the aluminum tube passes out from the outlet end of the straightening machine 1 and passes between the two abrasive belts 52. Since the distance between the two abrasive belts 52 is smaller than the diameter of the aluminum tube, the abrasive belts 52 are tightened and the abrasive belts 52 are in contact with the aluminum tube. The drive motor 41 is started and the shaft ring 32 is driven by the drive motor 41 to rotate, so that the abrasive belts 52 rotate around the aluminum tube to achieve a grinding effect.

[0031] While the sanding belt assembly 5 rotates, the planetary gear 53 revolves along the seat ring 31. When the planetary gear 53 is engaged with the inner ring gear 35, the planetary gear 53 rotates and drives the winding roller 54 to rotate, thereby causing the sanding belt 52 to rotate, so that the sanding belt 52 can more fully grind the aluminum tube, further improving the grinding effect.

[0032] Unless otherwise specified or one preferred or optional technical means is further limited to another technical means, the preferred and optional technical means disclosed in the present utility model can be arbitrarily combined to form several different technical solutions. Therefore, equivalent changes made according to the claims are still within the scope covered by the present utility model.
