[0014] The present invention provides a polishing device for hardware processing. It has the following beneficial effects:

[0015] (1). The polishing device for hardware processing fixes the hollow disc-shaped parts by setting a fixing device. By placing the hollow disc-shaped parts above the disc-shaped base, and then rotating the control rod to make the bilateral cam rotate, two movable plates are simultaneously squeezed to move away from each other, thereby positioning the hollow disc-shaped parts on the disc-shaped base. At the same time, a limiting structure is used to real-time position the gear fixed at the bottom of the bilateral cam, thereby positioning the position of the bilateral cam, ensuring the stability of fixing the hollow disc-shaped parts.

[0016] (2). The polishing device for hardware processing applies a polishing agent to the surface of the hollow disc-shaped parts by setting an application device. When the hollow disc-shaped parts are fixed on the disc-shaped base, by moving the extrusion plate to squeeze the first airbag, the first air pressure rod pushes the rotating plate to rotate, moving the polishing agent storage bin and the application pipeline to a vertical state. Subsequently, through the rotation of the rotating motor, the arc-shaped rod on the rotating rod squeezes the third airbag, enabling the gas inside it to enter the polishing agent storage bin. Through air pressure, the paste-like polishing agent is applied to the hollow disc-shaped parts through the application pipeline, achieving the effect of equal automatic application.

[0017] (3). The polishing device for hardware processing controls the closing and opening of the bottom of the application pipeline by setting a control device. When the rotating plate rotates to a vertical state, the second airbag at its bottom is squeezed, and the second air pressure rod pushes the closing plate to rotate, thereby releasing the closing of the application pipeline, which can effectively reduce the leakage of the paste-like polishing agent caused by external force factors.

[0018] (4). The polishing device for hardware processing performs polishing operations by setting a polishing equipment. By moving the slider to control the movement of the polishing machine, a convenient and controllable polishing operation is achieved. While the slider moves downward, the T-shaped rod squeezes the third air pressure rod, causing the two fourth air pressure rods to simultaneously push the two collection boxes and the baffles to move. The design of the two baffles can prevent the polishing agent from splashing during the polishing process. At the same time, collection boxes are arranged on both sides of the two baffles facing each other to collect the polishing agent splashed on the baffles. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Please refer to Figure 1-6, the present invention provides a technical solution: a polishing device for hardware processing, including an equipment base 1. A rotating motor 2 is fixed inside the equipment base 1. A fixing device 3 is fixed at the rotating shaft of the rotating motor 2. The fixing device 3 includes a rotating rod 31. A disc-shaped base 32 is fixed at the top of the rotating rod 31. A circular opening is provided at the top of the disc-shaped base 32. Two movable plates 34 are symmetrically and slidably connected inside the disc-shaped base 32 through two slide rails. An arc-shaped rod 33 is fixed outside the rotating rod 31. A first elastic sheet is provided between each of the two movable plates 34 and the inner wall of the disc-shaped base 32. A gear 35 is rotatably connected at the bottom of the inner wall of the disc-shaped base 32 between the two movable plates 34. A double-sided cam 36 is fixed at the top of the gear 35. A control rod 37 is fixed at the top of the double-sided cam 36. A limiting structure 38 is fixed at the bottom of the inner wall of the disc-shaped base 32. The hollow disc-shaped part is fixed by setting the fixing device 3. By placing the hollow disc-shaped part above the disc-shaped base 32, and then rotating the control rod 37 to make the double-sided cam 36 rotate, thereby simultaneously squeezing the two movable plates 34 to move away from each other, so as to position the hollow disc-shaped part on the disc-shaped base 32. At the same time, the position of the gear 35 fixed at the bottom of the double-sided cam 36 is positioned in real time through the limiting structure 38, so as to position the position of the double-sided cam 36, ensuring the stability of fixing the hollow disc-shaped part.

[0028] Furthermore, the limiting structure 38 includes a rectangular outer shell 381. A limiting rod 382 is penetrated and slidably connected inside the rectangular outer shell 381. One end of the limiting rod 382 is of a double bevel structure, and a reset pull rope 383 is fixed at the other end of the limiting rod 382. The limiting rod 382 is connected to the rectangular outer shell 381 through a second elastic sheet and a third elastic sheet, and the second elastic sheet and the third elastic sheet are installed in a mirror image. Under the cooperation of the second elastic sheet and the third elastic sheet, the limiting rod 382 has a highly elastic and movable motion state. Through the cooperation with the gear 35, the effect of positioning the double-sided cam 36 in real time is achieved.

[0029] Furthermore, a coating device 4 is provided at the top plate of the equipment base 1. The coating device 4 includes a rotating plate 41, a pressing plate 42, and a first air pressure chamber 43. The rotating plate 41 is rotatably connected to the top plate, the pressing plate 42 is slidably connected inside the equipment base 1, the first air pressure chamber 43 is fixed inside the equipment base 1, a first airbag 44 is fixed at one end of the first air pressure chamber 43, a first air pressure rod 45 is slidably connected inside the other end of the first air pressure chamber 43, and the first air pressure rod 45 is fixedly connected to the rotating plate 41. A polishing agent storage bin 46 is fixed on the right side of the rotating plate 41, a coating pipeline 47 is fixed at the bottom of the polishing agent storage bin 46, a control device 48 is arranged at the bottom of the polishing agent storage bin 46, an air pressure pipeline 49 is fixed at the front end of the rotating plate 41, a third airbag 410 is fixed at one end of the air pressure pipeline 49, and the other end of the air pressure pipeline 49 communicates with the polishing agent storage bin 46. An air inlet valve is embedded at the top of the polishing agent storage bin 46, and a one-way feeding pipeline is fixed on the right side of the polishing agent storage bin 46. By setting the coating device 4 to coat the polishing agent on the surface of the hollow disc-shaped part, when the hollow disc-shaped part is fixed on the disc-shaped base 32, by moving the pressing plate 42 to squeeze the first airbag 44, the first air pressure rod 45 is pushed to drive the rotating plate 41 to rotate, so that the polishing agent storage bin 46 and the coating pipeline 47 are moved to a vertical state. Subsequently, through the rotation of the rotating motor 2, the arc-shaped rod 33 on the rotating rod 31 squeezes the third airbag 410, so that the gas inside it enters the polishing agent storage bin 46, and the paste-like polishing agent is coated on the hollow disc-shaped part through the coating pipeline 47 by air pressure, realizing the effect of equal automatic coating.

[0030] It should be noted that the control device 48 includes a support rod 481 and a second air pressure chamber 482. A closing plate 483 is rotatably connected to the bottom of the support rod 481. A fourth elastic sheet is arranged between the closing plate 483 and the support rod 481. A second airbag 485 is fixed at one end of the second air pressure chamber 482. A second air pressure rod 484 is slidably connected inside the other end of the second air pressure chamber 482. The second air pressure rod 484 is fixedly connected to the left side of the closing plate 483. The second airbag 485 is located at the bottom of the rotating plate 41, and the right side of the closing plate 483 is located at the bottom of the discharge port of the coating pipeline 47. By setting the control device 48 to control the closing and opening of the bottom of the coating pipeline 47, when the rotating plate 41 rotates to a vertical state, the second airbag 485 at its bottom is squeezed, and the closing plate 483 is pushed to rotate through the second air pressure rod 484, thereby releasing the closing of the coating pipeline 47, which can effectively reduce the leakage of the paste-like polishing agent caused by external force factors.

[0031] It should be noted that a polishing device 5 is fixed on the right side of the upper surface of the equipment base 1. The polishing device 5 includes an L-shaped bracket 51. One side of the L-shaped bracket 51 is slidably connected with a slider 52. The other end of the L-shaped bracket 51 is fixed with a three-way air pressure chamber 58. A polishing machine 53 is embedded in the slider 52. A T-shaped rod 54 is fixed on the right side of the slider 52. The T-shaped rod 54 penetrates through the L-shaped bracket 51. The T-shaped rod 54 is elastically connected with the L-shaped bracket 51 through two springs. The front end and the back of the L-shaped bracket 51 are both slidably connected with baffles 55. One end of the two baffles 55 facing each other is fixed with a collection box 56. The upper surfaces of the two collection boxes 56 are both fixed with arc-shaped plates 57. The upper end inside the three-way air pressure chamber 58 is slidably connected with a third air pressure rod 59. The top of the third air pressure rod 59 is fixed with the T-shaped rod 54. The other two ends inside the three-way air pressure chamber 58 are both slidably connected with fourth air pressure rods 510. The two fourth air pressure rods 510 are respectively fixed to the backs of the two collection boxes 56. By setting the polishing device 5 for polishing operations, the movement of the polishing machine 53 is controlled by moving the slider 52, so as to achieve a convenient and controllable polishing operation. While moving the slider 52 downward, the third air pressure rod 59 is squeezed by the T-shaped rod 54, so that the two fourth air pressure rods 510 simultaneously push the two collection boxes 56 and the baffles 55 to move. The design of the two baffles 55 can prevent the polishing agent from splashing during the polishing process. At the same time, through the collection boxes 56 arranged on the two baffles 55, the polishing agent splashing on the baffles 55 is collected.

[0032] During use, first place the hollow disc part above the disc-shaped base 32. Subsequently, rotate the control rod 37 to rotate the double-sided cam 36, thereby simultaneously squeezing the two movable plates 34 to move away from each other, so that the two movable plates 34 respectively abut against the inner walls of the hollow parts of the hollow disc part, thereby positioning the hollow disc part on the disc-shaped base 32. At the same time, under the cooperation of the second elastic piece and the third elastic piece, the limiting rod 382 has a highly elastic and movable state of motion. Through the cooperation with the gear 35, the effect of real-time positioning of the double-sided cam 36 is realized, ensuring the stability of fixing the hollow disc part.

[0033] Subsequently, when the hollow disc part is fixed on the disc-shaped base 32, the airbag 44 is squeezed by moving the extrusion plate 42. At this time, the gas in the airbag 44 enters the air pressure chamber 43, causing the air pressure rod 45 to push the rotating plate 41 to rotate, moving the polishing agent storage bin 46 and the coating pipeline 47 to a vertical state. The airbag 485 at the bottom of the rotating plate 41 is squeezed, and the closing plate 483 is pushed to rotate by the air pressure rod 484, thereby releasing the closing of the coating pipeline 47, effectively reducing the leakage of the paste polishing agent caused by external force factors. Subsequently, through the rotation of the rotating motor 2, the arc-shaped rod 33 on the rotating rod 31 squeezes the airbag 410, causing the gas inside it to enter the polishing agent storage bin 46, and the paste polishing agent is applied to the hollow disc part through the coating pipeline 47 by air pressure, achieving the effect of equal automatic application;

[0034] Finally, start the polishing machine 53, control the movement of the polishing machine 53 by moving the slider 52, thereby realizing a convenient and controllable polishing operation. While the slider 52 moves downward, the air pressure rod 59 is squeezed by the T-shaped rod 54, causing the two air pressure rods 510 to simultaneously push the two collection boxes 56 and the baffle 55 to move. The design of the two baffles 55 can prevent the polishing agent from splashing during the polishing process. At the same time, through the collection boxes 56 provided on the two baffles 55, the polishing agent splashing on the baffle 55 is collected.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
