Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figure 1-8 , the present invention provides a polishing device for the iron ball head of a sewing machine, including a base 1. A control cabinet 36 for controlling the operation of the entire device is provided on the side of the base 1. A control console 37 of the control cabinet 36 is provided on one side above the base 1. An installation frame 2 is further provided above the base 1. A third motor 3 is fixedly connected to the installation frame 2. The output sliding end of the third motor 3 is fixedly connected to a chuck 4. An auxiliary clamping assembly corresponding to the chuck 4 is further provided above the base 1. A rough polishing assembly and a fine polishing assembly are installed on the installation frame 2. The rough polishing assembly includes a first mounting seat 5 fixedly connected to the installation frame 2. A first cylinder 6 is fixedly connected to the first mounting seat 5. The output sliding end of the first cylinder 6 is fixedly connected to a first connecting plate 7. A first motor 8 is fixedly connected to the first connecting plate 7. The output end of the first motor 8 is provided with a first tool rest 9. The first tool rest 9 is detachably connected with a rough polishing cutter head 10 (such as Figure 8As shown in the figure, the fine polishing assembly includes a second mounting seat 11 fixedly connected to the mounting frame 2. A second air cylinder 12 is fixedly connected to the second mounting seat 11. The output sliding end of the second air cylinder 12 is fixedly connected to a second connecting plate 13. A second motor 14 is fixedly connected to the second connecting plate 13. The output end of the second motor 14 is provided with a second tool holder 15. A fine polishing cutter head 16 is detachably connected to the second tool holder 15 (and since the overall structure of the fine polishing cutter head 16 is the same as that of the rough polishing cutter head 10, only the materials used for fine polishing are different, so the specific structure of the rough polishing cutter head 10 can be referred to Figure 8 the rough polishing cutter head 10). Polishing arc grooves 17 are formed on both the rough polishing cutter head 10 and the fine polishing cutter head 16. The control cabinet 36 is electrically connected to the first motor 8, the second motor 14, and the third motor 3 to respectively control the rotation speeds of the first motor 8, the second motor 14, and the third motor 3. Moreover, the control cabinet 36 is also electrically connected to the second air cylinder 12, the third air cylinder 21, and the first air cylinder 6 to achieve electrical control of each air cylinder.

[0027] In this embodiment, during polishing, the sewing machine iron ball head is clamped on the chuck 4, and the sewing machine iron ball head is assistedly clamped by the auxiliary clamping assembly. The third motor 3 is started, and the third motor 3 drives the chuck 4 to rotate. The chuck 4 drives the sewing machine iron ball head to rotate. The first cylinder 6 is used to drive the first motor 8 to move in the direction close to the sewing machine iron ball head, and move obliquely from top to bottom to approach the sewing machine iron ball head, and ensure that the rough polishing cutter head 10 contacts the surface of the sewing machine iron ball head, so that the polishing arc groove 17 on the rough polishing cutter head 10 can be closely fitted with the sewing machine iron ball head. Then the first motor 8 drives the rough polishing cutter head 10 to rotate to perform rough polishing on the sewing machine iron ball head. After the polishing is completed, the first cylinder 6 drives the rough polishing cutter head 10 to reset. The second cylinder 12 drives the fine polishing cutter head 16 to be close to the sewing machine iron ball head, and move horizontally from back to front to approach, so that the polishing arc groove 17 on the fine polishing cutter head 16 can be closely attached to the sewing machine iron ball head. Then the second motor 14 works to drive the fine polishing cutter head 16 to rotate to perform fine polishing on the sewing machine iron ball head. In this structure, since the rotation cutting directions of the rough polishing cutter head 10 and the fine polishing cutter head 16 form a right angle with the rotation direction of the sewing machine iron ball head, and the polishing surfaces of the rough polishing cutter head 10 and the fine polishing cutter head 16 form an acute angle, the polishing direction and area of the sewing machine iron ball head are finally improved, so that an all-round grinding effect on the ball head can be formed, and thus the surface of the sewing machine iron ball head can be comprehensively ground and polished, the edges and protrusions on the surface of the sewing machine iron ball head can be effectively removed, and the provided polishing arc groove 17 can make the rough polishing cutter head 10 and the fine polishing cutter head 16 closely fit the surface of the sewing machine iron ball head, so that the rough polishing cutter head 10 and the fine polishing cutter head 16 wrap one side of the sewing machine iron ball head for rough polishing and fine polishing, thereby further improving the polishing effect of the sewing machine iron ball head, and the surface of the final product is smoother. In this embodiment, the rough polishing cutter head 10 and the fine polishing cutter head 16 are detachably connected to the corresponding tool holders, which is convenient for replacing the worn polishing arc groove 17 after long-term use. In this structure, the rough polishing cutter head 10 and the fine polishing cutter head 16 can be fixed and locked to the corresponding tool holders by screws. After removing the screws later, the corresponding rough polishing cutter head 10 and the fine polishing cutter head 16 can be removed, which is convenient for users to replace.

The output end of the third cylinder 21 is rotatably connected to a clamping ejector rod 22 that cooperates with the chuck 4 for clamping the ball head. Two fixing plates 23 are fixedly connected to the fixed table 18. The same adjusting screw 24 is rotatably connected between the two fixing plates 23. A threaded hole matching the adjusting screw 24 is provided on the sliding table 20. The adjusting screw 24 passes through the sliding table 20 through the threaded hole.

[0029] In the above embodiment, by rotating the adjusting screw 24, the sliding table 20 can be driven to slide on the dovetail guide rail 19, so that the position of the sliding table 20 can be adjusted according to requirements. The third cylinder 21 drives the clamping ejector rod 22 to approach the sewing machine iron ball head, so that the sewing machine iron ball head can be limited and clamped. And the clamping ejector rod 22 can rotate following the sewing machine iron ball head, without hindering the normal rotation of the sewing machine iron ball head. Thus, the sewing machine iron ball head can be assisted in clamping, effectively improving the stability during the polishing process of the sewing machine iron ball head, thereby improving the polishing accuracy. And by setting the adjusting screw 24, the position of the sliding table 20 can be adjusted, and the clamping operation can be carried out on sewing machine iron ball heads of different lengths, improving the versatility of the equipment.

[0030] A collection box 25 is placed on the base 1. A movable magnet 26 is fixedly connected to the collection box 25. A fixed magnet 27 is fixedly connected to the base 1. The polarities of the sides of the movable magnet 26 and the fixed magnet 27 in contact with each other are opposite. The provided collection box 25 can facilitate the collection of dirt falling during the polishing process, improving the convenience of cleaning.

[0031] A hook 28 is fixedly connected to the vertical side wall of the mounting frame 2. A lubricating oil adding rod 29 is hung on the hook 28. During use, the lubricating oil adding rod 29 is taken off from the hook 28. One end of the lubricating oil adding rod 29 is smeared with solid lubricating oil. The lubricating oil adding rod 29 with solid lubricating oil is brought close to the sewing machine iron ball head, and the lubricating oil is smeared on the sewing machine iron ball head, thereby improving the polishing effect.

[0032] U-shaped brackets 30 are fixedly connected to both the first mounting seat 5 and the second mounting seat 11. Two trapezoidal guide grooves 31 are provided on the U-shaped brackets 30. Two trapezoidal sliders 32 are fixedly connected to both the first motor 8 and the second motor 14. The trapezoidal sliders 32 are located in the trapezoidal guide grooves 31. Through the mutual cooperation of the trapezoidal guide grooves 31 and the trapezoidal sliders 32, the first motor 8 and the second motor 14 can be supported, improving the stability of the movement and the operation of the first motor 8 and the second motor 14.

[0033] One end of the adjusting screw rod 24 is fixedly connected with a turntable 33. By rotating the turntable 33, the adjusting screw rod 24 can be rotated, which improves the convenience of rotating the adjusting screw rod 24.

[0034] A handle 34 is fixedly connected to the outer wall of the collection box 25, which improves the convenience of using the collection box 25.

[0035] A plurality of semi-circular grooves 35 are evenly formed on the outer edge of the turntable 33, which can improve the anti-slip performance of the turntable 33 and enhance the comfort of using the turntable 33.

[0036] Working principle: During polishing, the sewing machine iron ball head is clamped on the chuck 4, and the auxiliary clamping assembly is used to assist in clamping the sewing machine iron ball head. The third motor 3 is started, and the third motor 3 drives the chuck 4 to rotate. The chuck 4 drives the sewing machine iron ball head to rotate. The first cylinder 6 is used to drive the first motor 8 to move in the direction close to the sewing machine iron ball head, and move obliquely downward from top to bottom to approach the sewing machine iron ball head, and ensure that the rough polishing cutter head 10 contacts the surface of the sewing machine iron ball head, so that the polishing arc groove 17 on the rough polishing cutter head 10 can be closely fitted with the sewing machine iron ball head. Then, the first motor 8 drives the rough polishing cutter head 10 to rotate to perform rough polishing on the sewing machine iron ball head. After the polishing is completed, the first cylinder 6 drives the rough polishing cutter head 10 to reset. The second cylinder 12 drives the fine polishing cutter head 16 to approach the sewing machine iron ball head, and move horizontally from back to front to approach, so that the polishing arc groove 17 on the fine polishing cutter head 16 can be closely attached to the sewing machine iron ball head. Then, the second motor 14 operates to drive the fine polishing cutter head 16 to rotate to perform fine polishing on the sewing machine iron ball head. In this structure, since the rotation cutting directions of the rough polishing cutter head 10 and the fine polishing cutter head 16 form a right angle with the rotation direction of the sewing machine iron ball head, and the polishing surfaces of the rough polishing cutter head 10 and the fine polishing cutter head 16 form an acute angle, the polishing direction and area of the sewing machine iron ball head are finally improved, so that an all-round grinding effect on the ball head can be formed, and thus the surface of the sewing machine iron ball head can be comprehensively ground and polished, effectively removing the edges and protrusions on the surface of the sewing machine iron ball head. The provided polishing arc groove 17 can make the rough polishing cutter head 10 and the fine polishing cutter head 16 closely fit the surface of the sewing machine iron ball head, so that the rough polishing cutter head 10 and the fine polishing cutter head 16 wrap one side of the sewing machine iron ball head for rough polishing and fine polishing, thereby further improving the polishing effect of the sewing machine iron ball head, and the surface of the final product is smoother. In this embodiment, the rough polishing cutter head 10 and the fine polishing cutter head 16 are detachably connected to the corresponding tool holders, which is convenient for replacing the worn polishing arc groove 17 after long-term use. In this structure, the rough polishing cutter head 10 and the fine polishing cutter head 16 can be fixed and locked to the corresponding tool holders by screws. After removing the screws later, the corresponding rough polishing cutter head 10 and fine polishing cutter head 16 can be removed, which is convenient for users to replace. At the same time, it should be noted that the control cabinet 36 can control the rotation speed of the individual chuck 4, the rotation speeds of the rough polishing cutter head 10 and the fine polishing cutter head 16 according to requirements, so as to ensure higher final polishing accuracy and a smoother surface of the polished product.
