Description

Technical Field

[0001] This utility model relates to the field of polishing technology, and in particular to an automatic rotating mechanism for a semi-automatic wet sandblasting machine. Background Technology

[0002] In metal processing and manufacturing, wet sandblasting machines are commonly used surface treatment equipment for deburring, rust removal, and polishing of metal workpieces.

[0003] Traditional round tube sandblasting largely relies on manual operation, which is not only inefficient but also makes it difficult to ensure the uniformity and consistency of sandblasting. This is especially true when sandblasting and polishing the inside of the round tube, where the operation is more difficult and the skill requirements for workers are higher. To solve this problem, some existing semi-automatic or fully automatic sandblasting equipment has improved the efficiency and quality of sandblasting to some extent. However, these devices lack a dedicated round tube clamping mechanism. They can only hold the round tube with one hand and use the other hand to hold the sandblasting gun to sandblast and polish the inside of the round tube. This causes the round tube to shake during the sandblasting process, affecting the sandblasting effect and resulting in uneven sandblasting. Multiple operations are required to achieve the ideal surface finish. Therefore, we propose an automatic rotating mechanism for a semi-automatic wet sandblasting machine. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an automatic rotating mechanism for a semi-automatic wet sandblasting machine. This mechanism can solve the problem of the lack of a dedicated round tube clamping mechanism, which requires one hand to hold the round tube and the other hand to hold the sandblasting gun to sandblast and polish the inside of the round tube. This causes the round tube to shake easily during the sandblasting process, affecting the sandblasting effect, resulting in uneven sandblasting, and requiring multiple operations to achieve the ideal surface finish.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic rotating mechanism for a semi-automatic wet sandblasting machine, comprising:

[0006] Sandblasting control box, with a door hinged on one side;

[0007] A rotary positioning structure is located on the sandblasting control box;

[0008] The rotary positioning structure includes a drive motor, a rotating shaft, a positioning frame, a main bevel gear, and a rotating motor.

The rotating shaft is rotatably connected inside the sandblasting operation box. The positioning frame is fixedly connected to the end of the rotating shaft away from the drive motor. The interior of the positioning frame has four sliding grooves and a transmission groove. The outer surface of the positioning frame has four through grooves, all of which communicate with the interior of the corresponding sliding grooves. The rotating motor is fixedly installed on one side of the positioning frame. The output end of the rotating motor extends rotatably into the interior of the transmission groove and is fixedly connected to the main bevel gear. The main bevel gear is rotatably connected inside the transmission groove.

[0009] Preferably, the rotary positioning structure further includes four secondary bevel gears, four threaded rods, four connecting frames, and four clamping plates. The four threaded rods are rotatably connected in their respective sliding grooves. The opposite ends of the four threaded rods rotatably extend into the interior of the transmission groove and are fixedly connected to their respective secondary bevel gears. The four secondary bevel gears are meshed with the main bevel gears. The four connecting frames are threaded onto the outer surface of their respective threaded rods. The four connecting frames are slidably connected to the interior of their respective through grooves. The four clamping plates are fixedly connected to their respective connecting frames.

[0027] Please see Figure 1-5 This utility model provides a technical solution: an automatic rotating mechanism for a semi-automatic wet sandblasting machine, comprising:

[0028] Sandblasting control box 1, with a door hinged on one side;

[0029] A rotary positioning structure is located on the sandblasting operation box 1;

[0030] The rotary positioning structure includes a drive motor 5, a rotating shaft 9, a positioning frame 7, a rotary motor 10, and a main bevel gear 14. The drive motor 5 is fixedly installed on the side of the sandblasting operation box 1 away from the door.

The rotating shaft 9 is rotatably connected to the interior of the sandblasting operation box 1. The positioning frame 7 is fixedly connected to the end of the rotating shaft 9 away from the drive motor 5. The interior of the positioning frame 7 is provided with four sliding grooves 16 and a transmission groove 17. The outer surface of the positioning frame 7 is provided with four through grooves 19, all of which communicate with the interior of the corresponding sliding grooves 16. The rotary motor 10 is fixedly installed on one side of the positioning frame 7. The output end of the rotary motor 10 extends rotatably into the interior of the transmission groove 17 and is fixedly connected to the main bevel gear 14. The main bevel gear 14 is rotatably connected to the interior of the transmission groove 17.

[0031] The rotary positioning structure also includes four secondary bevel gears 15, four threaded rods 12, four connecting frames 13, and four clamping plates 18. The four threaded rods 12 are rotatably connected in the corresponding sliding grooves 16. The opposite ends of the four threaded rods 12 rotatably extend into the interior of the transmission groove 17 and are fixedly connected to the corresponding secondary bevel gears 15. The four secondary bevel gears 15 are meshed with the main bevel gears 14. The four connecting frames 13 are threaded onto the outer surface of the corresponding threaded rods 12. The four connecting frames 13 are slidably connected to the interior of the corresponding through grooves 19. The four clamping plates 18 are fixedly connected to the corresponding connecting frames 13.

[0032] A protective cover 11 is fixedly connected to the side of the positioning frame 7 near the rotating motor 10. The rotating motor 10 is located inside the protective cover 11. A heat dissipation groove is provided on the side of the protective cover 11 away from the positioning frame 7.

[0033] Furthermore, when using this device, the drive motor 5 and the rotary motor 10 are started by connecting an external power source.

This allows the four connecting frames 13 to drive the corresponding clamping plates 18 to clamp and fix the outside of the round tube, thereby enabling sandblasting treatment of the inside of the round tube and improving the stability of the round tube during the sandblasting process.

[0035] Working principle: By connecting to an external power source, the drive motor 5 and the rotary motor 10 are started. The rotary motor 10 drives the main bevel gear 14 to rotate. The rotation of the main bevel gear 14 drives the four secondary bevel gears 15 to rotate. The rotation of the four secondary bevel gears 15 drives the corresponding threaded rods 12 to rotate. The rotation of the four threaded rods 12 drives the corresponding connecting frame 13 to move horizontally under the guidance of the corresponding sliding groove 16. The movement of the four connecting frames 13 drives the corresponding clamping plate 18 to move, thereby facilitating the clamping and fixing of the outside of the round tube. When the positioning frame 7 is in a vertical position, the user can hold the sandblasting gun 6 to sandblast the inside of the round tube. The drive motor 5 drives the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 drives the positioning frame 7 to rotate, thereby facilitating the rotation of the positioning frame 7 to a horizontal position, which makes it easier for the user to place the sandblasted parts on the top of the positioning frame 7 for sandblasting.
