[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0036] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a turning machine tool and a turning method for the production of aluminum products.

[0037] Example 1: Please refer to Figure 1-Figure 5A turning machine tool and a turning method for aluminum product production include a bed 1, wherein a tool drive assembly 2, a regulating assembly 3, a pushing assembly 4, and a plurality of arc-shaped sanding plates 5 distributed in a circular array are installed above the inner cavity of the bed 1. The arc-shaped sanding plates 5 include a plurality of main sanding plates 51 and an auxiliary sanding plate 52. A mounting seat 6 for fixing a workpiece is installed below the inner cavity of the bed 1;

[0038] The tool drive assembly 2 includes a drill bit 21 that is vertically downward and rotatable, and the tool drive assembly 2 is used for cutting a workpiece;

[0039] The regulating assembly 3 is used to drive the drill bit 21 and the arc-shaped sand plate 5 to move vertically and rotate, and the pushing assembly 4 is used to drive the auxiliary sand plate 52 to swing;

[0040] An assembly plate 61 is installed above the mounting seat 6, and the assembly plate 61 is used to fix the workpiece and drive the workpiece to rotate;

[0041] Before fine processing, the workpiece is fixed by the mounting seat 6, and the regulating assembly 3 is operated, forcing the multiple curved sanding plates 5 to be inserted into the workpiece and then rotated, thereby pre-grinding the inner wall of the workpiece;

[0042] During fine machining, the regulating assembly 3 forces the tool drive assembly 2 to operate, forcing the drill bit 21 to grind the inner wall of the workpiece. At the same time, the regulating assembly 3 also forces multiple arc-shaped sanding plates 5 to move synchronously with the drill bit 21 to prevent grinding debris from being ejected into the processed area.

[0043] The workpiece is fixed on the assembly plate 61 by a fixture. In the initial state, the assembly plate 61 is horizontal, and the drill bit 21 is set directly above the assembly plate 61. The main sanding plate 51 and the auxiliary sanding plate 52 have the same structure. The diameter of the arc sanding plate 5 matches the diameter of the circular groove on the workpiece.

[0044] When in use, first fix the workpiece on the assembly plate 61 so that the circular groove on the workpiece faces upward, then start the regulating component 3, which controls multiple arc-shaped sanding plates 5 to move down into the circular groove on the workpiece at the same time, so that the arc-shaped sanding plates 5 fit the inner wall of the circular groove. Then, the regulating component 3 drives multiple arc-shaped sanding plates 5 to rotate, and the arc-shaped sanding plates 5 rub against the inner wall of the circular groove to achieve grinding, and pre-process the oxide scale and other defects. After that, the regulating component 3 is operated to move the arc-shaped sanding plates 5 up and away from the workpiece, and then start the pushing component 4, which drives the auxiliary sanding plates 52 to swing, and then The tool drive assembly 2 is restarted to force the drill bit 21 to rotate, and then the control assembly 3 is driven again, so that the main sanding plate 51 and the drill bit 21 are inserted into the circular groove of the workpiece and rotate synchronously. When the drill bit 21 grinds the inner wall of the circular groove, the main sanding plate 51 can protect other positions of the grinding point on the inner wall of the circular groove. Before the drill bit 21 grinds the bottom wall of the circular groove, the pushing assembly 4 drives the auxiliary sanding plate 52 to swing and then reset. Finally, the control assembly 3 drives all the curved sanding plates 5 to insert into the circular groove on the workpiece. When grinding, the curved sanding plates 5 protect the inner wall of the processed circular groove;

[0045] The turning machine tool is provided with a regulating component 3, an arc-shaped sanding plate 5, a tool driving component 2 and a pushing component 4, which can drive the arc-shaped sanding plate 5 to be inserted into the interior of the workpiece and then rotate, which is beneficial for pre-grinding the interior of the workpiece before fine-machining the workpiece, thereby removing oxide scales, reducing the probability of tool wear, and increasing the service life of the tool. It can also drive the arc-shaped sanding plate 5 and the drill bit 21 to rotate synchronously inside the workpiece, and then use the arc-shaped sanding plate 5 to block splashed debris when the drill bit 21 fine-machines the interior of the workpiece, thereby protecting the polished area, which is beneficial to improving the processing quality of the workpiece.

[0046] Example 2: See Figure 3-Figure 5 , different from the above embodiment, the regulating component 3 includes a vertical slide 31 fixed inside the bed 1, and a slide 32 is provided on the vertical slide 31. A main motor 33 is fixed on the slide 32. The output shaft of the main motor 33 faces downward and is fixed with a column seat 34. A disc 35 is fixed at the bottom of the column seat 34. The pushing component 4, the tool driving component 2 and the arc sanding plate 5 are all installed on the disc 35. The arc sanding plate 5 is arranged vertically, and a sanding surface is provided on the outer arc surface of the arc sanding plate 5.

[0047] Among them, the vertical slide 31 is an electric slide. When in use, the vertical slide 31 drives the slide 32 to move vertically after it is operated. When the slide 32 moves vertically, it drives the main motor 33, the column seat 34 and the disc 35 to move vertically, thereby driving the curved sanding plate 5, the pushing assembly 4 and the tool driving assembly 2 to move vertically, so as to drive the curved sanding plate 5 and the drill bit 21 to be inserted into the circular groove on the workpiece. When the main motor 33 is running, it drives the column seat 34 and the disc 35 to rotate, thereby driving the drill bit 21 and the curved sanding plate 5 to rotate synchronously.

[0048] By setting up the regulating component 3, the drill bit 21 can be driven to be inserted into the workpiece and then rotated so as to perform cutting processing on the inside of the workpiece. The regulating component 3 can also drive the arc-shaped sanding plate 5 to be inserted into the workpiece and then rotated, which can not only grind the inside of the workpiece before fine processing, but also provide protection for the processed area inside the workpiece during fine processing.

[0049] Example 3, see Figure 4-Figure 6 , different from the above embodiment, the surface of the disc 35 is provided with a plurality of radial slide grooves 36 distributed in an annular array, the top of the main sand plate 51 is fixed with a connecting frame 53, the connecting frame 53 is slidably connected to the radial slide groove 36, the column seat 34 is rotatably connected with an annular plate 37, the surface of the annular plate 37 is provided with a plurality of arc holes 38 distributed in an annular array, the top of the connecting frame 53 is fixed with a round pin 54, the round pin 54 extends into the arc hole 38, the top center of the annular plate 37 is fixed with a driven gear 39, the side of the column seat 34 is fixed with an auxiliary motor 310, the output shaft of the auxiliary motor 310 is fixed with a driving gear 311, and the driving gear 311 is meshed with the driven gear 39.

[0050] Among them, the number of radial slide grooves 36 and the connecting frame 53 are the same and match each other, the axis center of the driven gear 39 coincides with the axis center of the annular plate 37. When in use, after the regulating assembly 3 is operated, multiple main sanding plates 51 are driven to insert into the circular grooves on the workpiece, and the auxiliary motor 310 is started at this time. The auxiliary motor 310 drives the driving gear 311 to rotate, and when the driving gear 311 rotates, it drives the driven gear 39 to rotate, and when the driven gear 39 rotates, it drives the annular plate 37 to rotate. When the annular plate 37 rotates, the inner wall of the arc hole 38 pushes the round pin 54, and the round pin 54 drives the connecting frame 53 to slide along the radial slide groove 36, thereby driving the main sanding plate 51 to move radially. After the main sanding plate 51 moves radially, it clings to the inner wall of the circular groove. Then, after the regulating assembly 3 is operated again, it drives the main sanding plate 51 to rotate to achieve grinding;

[0051] By providing the auxiliary motor 310, the annular plate 37, the driving gear 311 and the driven gear 39, it is helpful to adjust the radial position of the main sanding plate 51 so that the main sanding plate 51 is closely attached to the inner wall of the circular groove on the workpiece, which is beneficial to improving the grinding effect. In addition, the main sanding plate 51 can also be adapted to circular grooves of different diameters, and has strong applicability.

[0052] Example 4, see Figure 5-10, different from the above embodiment, the tool drive assembly 2 includes an assembly frame 28, a drive motor 22 and a shaft seat 23, the assembly frame 28 is installed at the bottom of the disc 35 through an adjuster 27, the drive motor 22 is fixed on the assembly frame 28, the output shaft of the drive motor 22 is fixed with a driving wheel 24, the shaft seat 23 passes through the assembly frame 28 and is rotatably connected to the assembly frame 28, a driven wheel 25 is fixed at the top of the shaft seat 23, the driving wheel 24 is connected to the driven wheel 25 through a belt 26, the drill bit 21 is installed at the bottom of the shaft seat 23, the adjuster 27 includes a radial guide rail 271, a slider 272 is slidably connected to the radial guide rail 271, an adjusting motor 273 is fixed to the end of the radial guide rail 271, a screw 274 is fixed to the output shaft of the adjusting motor 273, the screw 274 passes through the slider 272 and is threadedly connected to the slider 272, the screw 274 is rotatably connected to both ends of the radial guide rail 271, and the assembly frame 28 is fixed to the bottom of the slider 272.

[0053] When in use, the driving motor 22 drives the driving wheel 24 to rotate, and the driving wheel 24 drives the driven wheel 25 to rotate through the belt 26. The driven wheel 25 rotates and drives the shaft seat 23 to rotate. The shaft seat 23 rotates and drives the drill bit 21 to rotate, thereby achieving cutting work. When the adjustment motor 273 is started, the screw 274 rotates, driving the slider 272 to slide along the radial guide rail 271. When the slider 272 slides, it drives the assembly frame 28 to move, thereby driving the drill bit 21 to move radially.

[0054] By setting a drive motor 22, the drill bit 21 can be driven to rotate, which is conducive to the cutting work. By setting a regulator 27, the drill bit 21 can be driven to move radially, which can cut the bottom wall of the circular groove on the workpiece and can adapt to circular grooves of different specifications.

[0055] Example 5, see Figure 4 and Figure 10 , different from the above embodiment, the pushing assembly 4 includes a cylinder 41 and a support rod 42, the top end of the support rod 42 is hinged to the end of the radial guide rail 271, the bottom end of the support rod 42 is fixedly connected to the top of the auxiliary sand plate 52, the cylinder 41 is fixed to the edge of the disc 35, the output end of the cylinder 41 is vertically downward and hinged with a movable block 43, and the movable block 43 is slidably connected to the surface of the support rod 42.

[0056] Among them, when processing the inner wall of the circular groove on the workpiece, the cylinder 41 is first started, and the cylinder 41 contracts to drive the movable block 43 to move upward, thereby pulling the support rod 42, and the support rod 42 swings around the top, driving the auxiliary sand plate 52 to swing, so that the auxiliary sand plate 52 is separated from the main sand plate 51, forming a gap. When processing the inner wall of the circular groove, the drill bit 21 is just moved into the gap through the regulator 27. When processing the bottom wall of the circular groove on the workpiece, the regulator 27 is operated to move the drill bit 21 to the inside of the main sand plate 51, and then the cylinder 41 is started again, the cylinder 41 extends, and drives the auxiliary sand plate 52 to reset. The main sand plate 51 and the auxiliary sand plate 52 provide protection for the side wall of the circular groove on the workpiece;

[0057] By setting the pushing assembly 4, it is beneficial to drive the auxiliary sand plate 52 to swing and form a gap when processing the side wall of the circular groove of the workpiece, so as to facilitate the processing of the drill bit 21, and to drive the auxiliary sand plate 52 to return to its original position when processing the bottom wall of the circular groove of the workpiece, which is beneficial to provide protection for the side wall of the circular groove.

[0059] When in use, the transmission motor 62 is started, and the transmission motor 62 drives the assembly plate 61 to rotate, thereby adjusting the angle of the workpiece, making it convenient to process other positions of the workpiece. At the same time, the processed position can be aligned with the air pipe 64 at the bottom. The air pipe 64 can spray the high-pressure airflow generated by the air compressor to the workpiece to clean up debris, which is more environmentally friendly.
