[0002] Mechanical components, in essence, are a combination of man-made physical parts, an indispensable part of the overall structure of a machine. They cooperate with other components of the machine to achieve its specific functions. The various parts of a mechanical component have definite relative motion relationships, which are precisely set according to the machine's design requirements and working principles.

[0003] When removing rust from mechanical parts, sandblasting is often used. However, when sandblasting tubular mechanical parts, it is necessary to clamp and fix their outer walls, which means that the clamped parts cannot be sandblasted directly. The clamping position needs to be changed, which is time-consuming and inconvenient. Therefore, a sandblasting device for rust removal on the surface of mechanical parts is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing sandblasting devices require clamping and fixing the outer wall of tubular mechanical parts when sandblasting to remove rust, which prevents sandblasting from being performed on the clamped part and requires repositioning the clamped part, resulting in a long time and inconvenience. Therefore, this invention proposes a sandblasting device for rust removal on the surface of mechanical parts.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-4 A rust removal and sandblasting device for mechanical parts includes a support plate 1, an extension plate 2 fixedly connected to one side of the support plate 1, a rectangular shell 3 fixedly connected to the top of the extension plate 2, a sliding groove 4 opened on the top of the support plate 1 and the extension plate 2, a first drive motor 5 installed on one side of the support plate 1, a first threaded rod 6 connected to the output end of the first drive motor 5, a movable plate 7 threadedly connected to the first threaded rod 6, the movable plate 7 being slidably connected to the sliding groove 4, a fixing mechanism provided on the movable plate 7, an adjustment mechanism provided on the top of the rectangular shell 3, and support legs fixedly connected to the bottom of the support plate 1 and the extension plate 2.

[0021] The first drive motor 5 is powered by an external device and its opening and closing are controlled. The first drive motor 5 drives the first threaded rod 6 to rotate. The first threaded rod 6 drives the moving plate 7 to move out of the rectangular shell 3 and place the tubular mechanical parts on the cylinder 9. The fixing structure fixes them. Then the moving plate 7 moves back into the rectangular shell 3, which facilitates the placement and removal of the tubular mechanical parts.

[0022] Furthermore, the fixing mechanism includes a base block 8, a cylinder 9, a spring 10, and a trapezoidal locking block 11. The top of the base block 8 is fixedly connected to the cylinder 9. The cylinder 9 has first rectangular slots on both sides. One end of the spring 10 is fixedly connected to the first rectangular slot, and the other end of the spring 10 is fixedly connected to the trapezoidal locking block 11. The trapezoidal locking block 11 is slidably connected to the first rectangular slot, and the base block 8 is fixedly connected to the top of the movable plate 7.

[0023] In this process, the tubular mechanical component slides down along the cylinder 9 and continues to press down when it contacts the trapezoidal locking block 11. The tubular mechanical component slides along the inclined plate of the trapezoidal locking block 11, the spring 10 contracts, and the trapezoidal locking block 11 is retracted into the first rectangular groove. Under the elastic action of the spring 10, the trapezoidal locking block 11 is locked onto the inner wall of the tubular mechanical component, thus fixing it.

[0024] Furthermore, the adjustment mechanism includes a mounting frame 12, a second drive motor 13, a second threaded rod 14, and a connecting plate 15. The second drive motor 13 is mounted on the top of the mounting frame 12, and the output end of the second drive motor 13 is connected to the second threaded rod 14. The second threaded rod 14 is connected to the threaded rod of the connecting plate 15.

[0025] A second rectangular groove is provided on one side of the mounting bracket 12, and the connecting plate 15 is slidably connected to the second rectangular groove. A rectangular opening is provided on the top of the rectangular shell 3, and the connecting plate 15 is located inside the rectangular opening.

[0026] A sandblasting machine 16 is installed on the top of the rectangular shell 3. The two ends of the sandblasting machine 16 are connected to the discharge hoses 17. The discharge hoses 17 are fixedly connected to the collection box 18. The bottom of the collection box 18 is fixedly connected to the connecting pipe 19. One end of the connecting pipe 19 is connected to the collection ring 20. Several nozzles 21 are installed on the inner ring of the collection ring 20. The connecting plate 15 is fixedly connected to the top of the collection box 18.

[0027] The second drive motor 13 is powered by an external device and its opening and closing are controlled. The sandblasting machine 16 delivers the abrasive material from the discharge hose 17 to the collection box 18. A control valve is installed on the connecting pipe 19 to control the abrasive material to enter the collection ring 20 through the connecting pipe 19. The abrasive material in the collection ring 20 is sprayed out through the nozzle 21. At the same time, the second drive motor 13 drives the second threaded rod 14 to rotate. The second threaded rod 14 drives the connecting plate 15 to descend. The connecting plate 15 drives the collection box 18 to descend, so that the nozzle 21 can uniformly sandblast and remove rust from the surface of the tubular mechanical parts from top to bottom.

[0028] The length of the discharge hose 17 is sufficient to connect to the collection box 18 that needs to rise and fall;

[0029] This invention can simultaneously perform rust removal and sandblasting on up to six tubular mechanical parts, further improving work efficiency.

[0030] Meanwhile, the specific model and specifications of the first drive motor 5 and the second drive motor 13 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0031] Furthermore, limiting plates 22 are fixedly connected to both sides of the collection box 18, and limiting grooves are opened on the inner walls of both sides of the rectangular shell 3. The limiting plates 22 are slidably connected to the limiting grooves. A circular hole is opened on the top of the rectangular shell 3, and the discharge hose 17 is located in the circular hole. A sliding door 23 is hinged to one side of the rectangular shell 3.

[0032] The limiting plate 22 and the limiting groove limit the material collection box 18, allowing the material collection box 18 to rise or fall stably. When the tubular mechanical parts are sandblasted, the sliding door 23 is closed to prevent the sprayed material from drifting into the air and causing air pollution.

[0033] The working principle of this utility model:

[0034] When the sliding door 23 is opened, the first drive motor 5 drives the first threaded rod 6 to rotate. The first threaded rod 6 drives the moving plate 7 to move out of the rectangular shell 3, and slides the tubular mechanical part down along the cylinder 9. When it contacts the trapezoidal block 11, it continues to press down. The tubular mechanical part slides along the inclined plate of the trapezoidal block 11. The spring 10 contracts, and the trapezoidal block 11 is put into the first rectangular groove. Under the elastic action of the spring 10, the trapezoidal block 11 is locked on the inner wall of the tubular mechanical part and fixed to it. Then the moving plate 7 moves into the rectangular shell 3 and closes the sliding door 23.

[0035] The sandblasting machine 16 delivers the abrasive material from the discharge hose 17 to the collection box 18. A control valve is installed on the connecting pipe 19 to control the abrasive material to enter the collection ring 20 through the connecting pipe 19. The abrasive material in the collection ring 20 is sprayed out through the nozzle 21. At the same time, the second drive motor 13 drives the second threaded rod 14 to rotate. The second threaded rod 14 drives the connecting plate 15 to descend. The connecting plate 15 drives the collection box 18 to descend, so that the nozzle 21 can uniformly sandblast and remove rust from the surface of the tubular mechanical parts from top to bottom.
