[0023] Example 1

[0024] like Figures 1-4As shown, the multi-pipe inner wall spraying and sandblasting positioning device proposed in this invention includes a positioning seat 1, a fixing frame 2, a positioning top plate 3, a positioning component, an ejection component, a power component, and a sandblasting component. The positioning seat 1 has a downward pressure groove in the middle, and the fixing frame 2 is set above it. Four guide posts 4 are symmetrically arranged between the bottom of the downward pressure groove and the fixing frame 2. The positioning top plate 3 is slidably arranged between the four guide posts 4. Multiple equally spaced arc-shaped grooves are opened on the opposite side of the positioning top plate 3 and the positioning seat 1. The fixing frame 2 is equipped with a positioning component that drives the positioning top plate 3 to rise and fall. An ejection component that cooperates with the positioning component is set on one side of the positioning top plate 3. A hollow groove 5 is opened in the middle of the fixing seat. The power component is set in the hollow groove 5. The sandblasting component that is slidably arranged with the hollow groove 5 is connected to the power component.

[0025] The positioning assembly includes a positioning motor 6, a bidirectional lead screw 7, a lead sleeve 8, and a connecting rod 9. The positioning motor 6 is installed at one end of the fixed frame 2, and the output end of the positioning motor 6 passes through the fixed frame 2 and is connected to the bidirectional lead screw 7. There are two sets of lead sleeves 8 and two sets of connecting rods 9. The two sets of lead sleeves 8 are connected to the bidirectional lead screw 7 with opposite threads. The connecting rod 9 is rotatably connected between the two sets of lead sleeves 8 and the positioning top plate 3. The bidirectional lead screw 7 is driven to rotate by the positioning motor 6. When the bidirectional lead screw 7 rotates, it drives the two lead sleeves 8 to move synchronously to both ends. The two lead sleeves 8 drive the positioning top plate 3 to descend through the connecting rod 9. The positioning top plate 3 and the positioning seat 1 cooperate to form a fixing slot to fix the 18 sandblasting pipes.

[0026] The ejection assembly includes a rotating shaft 10, a tilting push plate 11, gears a12 and racks a13. The rotating shaft 10 is rotatably mounted on the side of the fixed frame 2 via a rotating seat. The tilting push plate 11 is mounted on the rotating shaft 10. There are two sets of gears a12 and racks a13. Both sets of gears a12 are mounted on the rotating shaft 10, and both sets of racks a13 are mounted on the side of the positioning top plate 3. The two sets of racks a13 are meshed with the two sets of gears a12 respectively. When the sandblasting is completed, the positioning motor 6 drives the bidirectional lead screw 7 to reverse, and the positioning top plate 3 rises, thereby releasing the pipe. During the rise, the racks a13 rise. When the racks a13 rise, they mesh with the gears a12. The meshing force drives the rotating shaft 10 to rotate the tilting push plate 11. During the rotation of the tilting push plate 11, a portion of the pipe is pushed out from one end of the positioning seat 1, making it convenient for subsequent workers to unload the material.

[0027] Furthermore, a vertical section 27 is provided at one end of the flip-up push plate 11. The vertical section 27 is located above one end of the positioning seat 1. When the flip-up push plate 11 rotates under the action of the rotating shaft 10, the pipe is pushed out from one end of the positioning seat 1 through the vertical section 27.

[0028] The working principle of this invention is as follows: In use, the 18 pipes to be sandblasted are placed on the arc-shaped groove of the positioning seat 1. Then, the positioning motor 6 is started. The positioning motor 6 drives the bidirectional lead screw 7 to rotate. As the bidirectional lead screw 7 rotates, the two threaded sleeves 8 drive one end of each of the two connecting rods 9 to move synchronously towards both ends of the bidirectional lead screw 7. During the movement, the other ends of the two connecting rods 9 drive the positioning top plate 3 to descend smoothly under the limit of the guide post 4 until the pipes are fixed. Through the cooperation of the positioning components, the accuracy of positioning multiple pipes can be ensured. The cooperation between the positioning top plate 3 and the positioning seat 1 provides stable support and positioning, avoiding pipe offset and swaying, and ensuring... Sandblasting effect; During the fixing process, the positioning top plate 3 drives the rack a13 to descend, and the rack a13 meshes with the gear a12, driving the rotating shaft 10 to drive the flipping push plate 11 to rotate until one end of it is above one end of the positioning seat 1. After the sandblasting is completed, the positioning top plate 3 is driven to rise through the positioning component. At this time, the pipe is in the unfixed state. When the positioning top plate 3 rises, it drives the rack a13 to rise. When the rack a13 rises, it meshes with the gear a12. The meshing force drives the rotating shaft 10 to drive the flipping push plate 11 to rotate. During the rotation of the flipping push plate 11, a part of the pipe is pushed out of the positioning seat 1 from one end of the positioning seat 1, which is convenient for subsequent workers to unload the material.

[0029] Example 2

[0030] like Figures 1-4 As shown, the multi-pipe inner wall spraying and sandblasting positioning device proposed in this invention, based on the above embodiments, discloses in detail the specific components of the power assembly and the sandblasting assembly. The power assembly includes a drive motor 14, a screw 15, and a nut assembly 16. The drive motor 14 is mounted at one end of the hollow groove 5 via a mounting bracket. The output end of the drive motor 14 is connected to the screw 15, and the nut assembly 16 is threaded onto the screw 15. The sandblasting assembly includes an L-shaped moving plate 17, sandblasting pipes 18, and sandblasting heads 19. The L-shaped moving plate 17 is connected to the nut assembly 16. Multiple sandblasting pipes 18 are rotatably arranged on the inner side of the L-shaped moving plate 17, and the multiple sandblasting pipes 18 are respectively located between two corresponding arc-shaped grooves. One end of the multiple sandblasting pipes 18 is connected to the sandblasting head 19. A transmission assembly for driving the sandblasting pipes 18 to rotate is arranged on the outer side of the L-shaped moving plate 17.

[0031] The transmission assembly includes a transmission shaft 20, gears b21, racks b22, main bevel gears 23, and driven bevel gears 24. The transmission shaft 20 is rotatably mounted at one end of the L-shaped movable plate 17 via a bushing. Two sets of gears b21 and racks b22 are provided, with the two sets of gears b21 respectively mounted at both ends of the transmission shaft 20, and the two sets of racks b22 respectively mounted at both ends of the side of the positioning seat 1. The two sets of racks b22 are meshed with the two sets of gears b21. Multiple sets of main bevel gears 23 and driven bevel gears 24 are provided, with multiple sets of main bevel gears 23 equidistantly mounted on the transmission shaft 20. Each set of bevel teeth 24 is installed at one end of the sandblasting pipe 18. Multiple sets of bevel teeth 24 are respectively meshed with the corresponding main bevel teeth 23. When the L-shaped moving plate 17 moves horizontally under the action of the power component, it drives the transmission shaft 20 to move synchronously. The gears b21 and rack b22 at both ends of the transmission shaft 20 are in a meshing state. The meshing force drives the transmission shaft 20 to rotate. When rotating, it drives the main bevel teeth 23 on its body to rotate. The main bevel teeth 23 drive the sandblasting pipe 18 to drive the sandblasting head 19 to rotate inside the pipe by meshing with the bevel teeth 24, which improves the uniformity of the sandblasting process.

[0032] Furthermore, a T-shaped plate 25 is connected to the inner end face of the L-shaped moving plate 17, and a T-shaped groove 26 that cooperates with the T-shaped plate 25 is provided on the inner side of the positioning seat 1. The movement trajectory of the L-shaped moving plate 17 relative to the fixed seat 1 is limited by the cooperation of the T-shaped plate 25 and the T-shaped groove 26, so as to ensure the smooth operation of the L-shaped moving plate 17 when the power component drives it to move.

[0033] In this embodiment, during use, after the pipe is fixed in place with the cooperation of the positioning component, the drive motor 14 is started. The drive motor 14 drives the screw 15 to rotate. When the screw 15 rotates, the nut assembly 16 drives the L-shaped moving plate 17 to move, so that the sandblasting pipe 18 on the side of the L-shaped moving plate 17 drives the sandblasting head 19 to extend into the pipe. As the L-shaped moving plate 17 continues to move, the inner wall of the pipe is sandblasted from front to back. At the same time, during the sandblasting process, the continuous movement of the L-shaped moving plate 17 will drive the transmission shaft 20. Synchronous movement occurs when the gears b21 and rack b22 at both ends of the drive shaft 20 are engaged. The meshing force drives the drive shaft 20 to rotate, which in turn drives the main bevel gear 23 on its body to rotate. The main bevel gear 23, through meshing with the secondary bevel gear 24, drives the sandblasting pipe 18 to rotate the sandblasting head 19 inside the pipe, resulting in a more uniform distribution and thus achieving a uniform sandblasting effect. The sandblasting medium can be covered at every position inside the pipe, ensuring the consistency of the overall sandblasting effect and achieving an all-directional coverage effect.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
