[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned 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 Figures 1-5A turning machine tool and a turning method for producing aluminum products, comprising a bed 1, wherein a tool driving assembly 2, a control assembly 3, a pushing assembly 4 and a plurality of arc-shaped sanding plates 5 arranged in a ring array are installed above the inner cavity of the bed 1, wherein the arc-shaped sanding plates 5 include a plurality of main sanding plates 51 and a secondary sanding plate 52, and a mounting seat 6 for fixing the workpiece is installed below the inner cavity of the bed 1.

[0038] The tool drive assembly 2 includes a vertically downward-facing and rotatable drill bit 21, which is used for cutting and machining the workpiece.

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

[0040] An assembly plate 61 is mounted on the top of the mounting base 6. 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 base 6, and the control component 3 is rotated to force multiple arc-shaped sanding plates 5 to be inserted into the workpiece and then rotated, thereby pre-processing the inner wall of the workpiece by grinding.

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

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

[0044] In use, the workpiece is first fixed on the assembly plate 61 with the circular groove on the workpiece facing upwards. Then, the control component 3 is activated, which controls multiple arc-shaped abrasive plates 5 to simultaneously move downwards into the circular groove on the workpiece, so that the arc-shaped abrasive plates 5 fit against the inner wall of the groove. Afterwards, the control component 3 drives the multiple arc-shaped abrasive plates 5 to rotate, and the arc-shaped abrasive plates 5 rub against the inner wall of the groove to achieve polishing, pre-treating oxide scale and other defects. After the control component 3 operates, the arc-shaped abrasive plates 5 are moved upwards and detached from the workpiece. Then, the push component 4 is activated, which drives the auxiliary abrasive plate 52 to swing. Restart the tool drive assembly 2 to force the drill bit 21 to rotate, and then drive the control assembly 3 again so that the main sand 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 sand 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 push assembly 4 re-drives the auxiliary sand plate 52 to swing and then reset. Finally, the control assembly 3 drives all the arc-shaped sand plates 5 to insert into the circular groove on the workpiece. When grinding, the arc-shaped sand plates 5 protect the inner wall of the processed circular groove.

[0045] This turning machine tool, through the setting of control component 3, arc-shaped sanding plate 5, tool drive component 2, and push component 4, can drive the arc-shaped sanding plate 5 to rotate after being inserted into the workpiece. This is beneficial for pre-grinding the inside of the workpiece before finishing, thereby removing oxide scale, reducing the probability of tool wear, and improving tool life. It can also drive the arc-shaped sanding plate 5 and the drill bit 21 to rotate synchronously inside the workpiece. Then, when the drill bit 21 is finishing the inside of the workpiece, the arc-shaped sanding plate 5 is used to shield the splashed debris, thereby protecting the ground area and improving the machining quality of the workpiece.

[0046] Example 2: See Figures 3-5 Unlike the above embodiments, the control component 3 includes a vertical slide 31 fixed inside the bed 1. A slide seat 32 is provided on the vertical slide 31. A main motor 33 is fixed on the slide seat 32. The output shaft of the main motor 33 faces downward and is fixed with a column base 34. A disc 35 is fixed at the bottom of the column base 34. The pushing component 4, the tool driving component 2, and the arc-shaped sanding plate 5 are all mounted on the disc 35. The arc-shaped sanding plate 5 is vertically arranged, and a sanding surface is provided on the outer arc surface of the arc-shaped 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. When the slide 32 moves vertically, it drives the main motor 33, the column base 34 and the disc 35 to move vertically, which in turn drives the arc-shaped sand plate 5, the pushing component 4 and the tool driving component 2 to move vertically, so as to drive the arc-shaped sand plate 5 and the drill bit 21 to insert into the circular groove on the workpiece. When the main motor 33 runs, it drives the column base 34 and the disc 35 to rotate, which in turn drives the drill bit 21 and the arc-shaped sand plate 5 to rotate synchronously.

[0048] By setting the control component 3, the drill bit 21 can be driven to rotate after being inserted into the workpiece, so as to perform cutting processing on the inside of the workpiece. The control component 3 can also drive the arc-shaped sanding plate 5 to rotate after being inserted into the workpiece, which can not only grind the inside of the workpiece before finishing, but also provide protection for the machined area inside the workpiece during finishing.

[0049] Example 3, see Figures 4-6 Unlike the above embodiments, the surface of the disc 35 is provided with a plurality of radially arranged grooves 36 in an annular array. A connecting frame 53 is fixed to the top of the main sand plate 51. The connecting frame 53 is slidably connected to the radially arranged grooves 36. An annular plate 37 is rotatably connected to the column base 34. The surface of the annular plate 37 is provided with a plurality of arc-shaped holes 38 in an annular array. A round pin 54 is fixed to the top of the connecting frame 53. The round pin 54 extends into the arc-shaped hole 38. A driven gear 39 is fixed to the top center of the annular plate 37. An auxiliary motor 310 is fixed to one side of the column base 34. A driving gear 311 is fixed to the output shaft of the auxiliary motor 310. The driving gear 311 meshes with the driven gear 39.

[0050] The radial grooves 36 and connecting brackets 53 are the same in number and matched with each other. The axis of the driven gear 39 coincides with the axis of the annular plate 37. In use, after the control component 3 is turned on, it drives multiple main sanding plates 51 to be inserted into the circular groove on the workpiece. At this time, the auxiliary motor 310 is started. The auxiliary motor 310 drives the drive gear 311 to rotate. When the drive gear 311 rotates, it drives the driven gear 39 to rotate. 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-shaped hole 38 pushes the round pin 54. The round pin 54 drives the connecting bracket 53 to slide along the radial groove 36, thereby driving the main sanding plate 51 to move radially. After the main sanding plate 51 moves radially, it is pressed against the inner wall of the circular groove. Then, after the control component 3 is turned on again, it drives the main sanding plate 51 to rotate, thus realizing grinding.

[0051] By setting up the auxiliary motor 310, the annular plate 37, the driving gear 311 and the driven gear 39, it is beneficial to adjust the radial position of the main sanding plate 51, so that the main sanding plate 51 is in close contact with the inner wall of the circular groove on the workpiece, which is beneficial to improve the grinding effect. In addition, the main sanding plate 51 can adapt to circular grooves of different diameters, making it highly adaptable.

[0052] Example 4, see Figures 5-10Unlike the above embodiments, the tool drive assembly 2 includes an assembly frame 28, a drive motor 22, and a shaft seat 23. The assembly frame 28 is mounted on the bottom of the disc 35 via an adjuster 27. The drive motor 22 is fixed on the assembly frame 28, and a drive wheel 24 is fixed to the output shaft of the drive motor 22. 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 to the top of the shaft seat 23. The drive wheel 24 is connected to the driven wheel 25 via a belt 26. The drill bit 21 is mounted on 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, and 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. The assembly frame 28 is fixed to the bottom of the slider 272.

[0053] When in use, the drive motor 22 drives the drive wheel 24 to rotate. When the drive wheel 24 rotates, it drives the driven wheel 25 to rotate through the belt 26. When the driven wheel 25 rotates, it drives the bearing 23 to rotate. When the bearing 23 rotates, it drives the drill bit 21 to rotate, thereby enabling 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 mounting frame 28 to move, thereby driving the drill bit 21 to move radially.

[0054] By setting the drive motor 22, the drill bit 21 can be driven to rotate, which is beneficial to the cutting work. By setting the adjuster 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 also adapt to circular grooves of different specifications.

[0055] Example 5, see Figure 4 and Figure 10 Unlike the above embodiments, the pushing component 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, and 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 is hinged to a movable block 43. The movable block 43 is slidably connected to the surface of the support rod 42.

[0056] When machining the inner wall of the circular groove on the workpiece, the cylinder 41 is started first. The cylinder 41 retracts and drives the movable block 43 to move upward, which in turn pulls the support rod 42. The support rod 42 swings around the top, causing the auxiliary sand plate 52 to swing, so that the auxiliary sand plate 52 separates from the main sand plate 51, forming a gap. When machining the inner wall of the circular groove, the drill bit 21 moves into the gap through the adjuster 27. When machining the bottom wall of the circular groove on the workpiece, the adjuster 27 moves the drill bit 21 to the inside of the main sand plate 51. 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 push component 4, it is beneficial to drive the auxiliary sand plate 52 to swing and form a gap when machining the side wall of the workpiece's circular groove, so that the drill bit 21 can process it. Furthermore, when machining the bottom wall of the workpiece's circular groove, the auxiliary sand plate 52 is driven to reset, which helps to protect the side wall of the circular groove.

[0058] Example 6, see Figure 11 Unlike the above embodiments, the mounting base 6 has a support 65 fixed on its top, a drive motor 62 fixed on the support 65, an assembly plate 61 fixed on the output shaft of the drive motor 62, a groove 63 on the top of the mounting base 6, an air pipe 64 fixed in the groove 63, one end of the air pipe 64 being connected to an air compressor, and the other end of the air pipe 64 facing the bottom of the assembly plate 61.

[0059] When in use, the drive motor 62 is started, which drives the assembly plate 61 to rotate, thereby adjusting the angle of the workpiece and facilitating the processing of 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 onto the workpiece to clean up debris, which is more environmentally friendly.

[0060] Example 7: A turning method for producing aluminum products. This turning method for producing aluminum products uses a turning machine tool from the above examples, including: before finishing the inside of the circular groove of the workpiece, grinding the oxide scale inside the circular groove; while machining the inside of the circular groove, using a shielding material to shield the machined area to avoid scratching it after being splashed by debris.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
