DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0023] Please refer to Figure 1 The metal shell sand blasting rust removal device in the embodiment comprises a box body 1, the top of the box body 1 is provided with a sand blasting mechanism extending into the inner cavity thereof, and the inner cavity wall of the bottom of the box body 1 is provided with a dust falling mechanism.

[0024] It can be understood that, through the arrangement of the sand blasting mechanism and the dust falling mechanism, the workpiece can be subjected to rust removal treatment, dust falling work in the device can be facilitated, environmental pollution can be reduced, and the use effect of the device can be improved.

[0025] It can also be understood that the inner cavity wall of the bottom of the box body 1 is fixed with a cylinder 11 and a servo motor 14, the top of the cylinder 11 is fixed with a connecting plate 12, the top of the connecting plate 12 is fixed with a ring plate 13, the ring plate 13 is in a ring structure, that is, the top of the ring plate 13 is provided with a movable opening extending to the bottom thereof, and the inner ring of the ring plate 13 is provided with a sliding channel in the form of a ring in communication with the movable opening.

[0026] The output shaft of the servo motor 14 is fixed with a rotating block 15, the top of the rotating block 15 is fixed with a receiving block 16, the receiving block 16 is provided with an adjusting part 17 movably connected with the ring plate 13, the adjusting part 17 is fixed with a rotating plate 18, the top of the rotating plate 18 is provided with a stabilizing mechanism 19, and the stabilizing mechanism 19 is movably connected with a shell 20.

[0027] It should be noted that, through the arrangement of the stabilizing mechanism 19, the sand blasting shell can be clamped and fixed, so that the stability of the device in use can be improved, the overall use effect can be improved, and through the movable connection between the adjusting part 17 and the ring plate 13, the angle adjusting function of the workpiece can be realized, so that the overall use effect can be improved.

[0028] It should also be noted that, through the arrangement of the movable opening and the sliding channel, the adjusting part 17 can be controlled and adjusted, so that the angle of the workpiece can be controlled, the rust removal work of the workpiece at different angles can be facilitated, and the rust removal effect can be improved.

[0029] Please refer to Figure 2To achieve angle adjustment of the workpiece, the adjusting component 17 in this embodiment includes a movable column 1701 slidably connected to the ring plate 13 via a sliding channel. A connecting plate 1702 is vertically fixed to the side of the movable column 1701 away from the ring plate 13, and a rotating column 1703 is vertically fixed to the side of the connecting plate 1702 away from the ring plate 13. The rotating column 1703 is rotatably inserted into the receiving block 16. That is, the movable column 1701, the connecting plate 1702, and the rotating column 1703 form a "Z"-shaped structure.

[0030] Specifically, the front of the receiving block 16 has a rotating opening that extends to its back. The rotating column 1703 is rotatably connected to the receiving block 16 through the rotating opening, and the rotating plate 18 is fixed to the outside of the rotating column 1703.

[0031] In this embodiment, the rotating port facilitates the rotation of the rotating column 1703, and the receiving block 16 supports the rotating column 1703, thereby improving the overall stability and enabling stable rotation and angle adjustment of the workpiece.

[0032] It should be explained that the arrangement of the movable column 1701 and the sliding channel facilitates the rotation of the overall adjusting component 17, thereby ensuring the stable rotation of the workpiece and the stable use of the entire device. Specifically, when the servo motor 14 is working, it drives the rotating block 15 and the receiving block 16 to rotate. The output shaft of the servo motor 14 is aligned with the central axis of the ring plate 13 and is parallel to the height direction of the housing 1. The rotation of the receiving block 16 causes the adjusting component 17 to rotate as a whole, and the movable column 1701 moves along the sliding channel, ensuring smooth and stable rotation of the adjusting component 17. The rotation of the adjusting component 17 causes the rotating plate 18, which is fixed to it, to rotate about the central axis of the ring plate 13, thereby causing the stabilizing mechanism 19 and the shell to be sandblasted 20 to rotate. This achieves the rotation of the shell to be sandblasted 20, facilitating uniform sandblasting and improving sandblasting efficiency.

[0033] When cylinder 11 is working, the output shaft of cylinder 11 extends and retracts along the height direction, driving the ring plate 13 to move up and down through the connecting plate 12. Since the movable column 1701 and the ring plate 13 are movably connected through the sliding channel, the movement of the ring plate 13 drives the movable column 1701 to move up and down. At the same time, due to the limiting effect of the receiving block 16 on the rotating column 1703, the height position of the rotating column 1703 remains unchanged. Since the rotating column 1703 is rotatably connected to the receiving block 16, the movement of the movable column 1701 drives the rotating column 1703 to rotate relative to the rotating opening of the receiving block 16, that is, drives the rotating column 1703 to rotate around its own axis, thereby driving the rotating plate 18 to swing, that is, driving the stabilizing mechanism 19 and the shell to be sandblasted 20 to swing around the axis of the rotating column 1703 as the swing axis, realizing the angle adjustment of the shell to be sandblasted 20, so as to improve the flexibility of use and the uniformity of sandblasting during the sandblasting process.

[0034] Please refer to Figure 3 In order to stabilize the workpiece rust removal, the stabilizing mechanism 19 in the embodiment includes a stabilizing drive assembly and two oppositely arranged action blocks 1906 connected to the output end of the stabilizing drive assembly. The stabilizing drive assembly can drive the two action blocks 1906 to approach or move away from each other to clamp or release the sandblasting shell 20.

[0035] Specifically, the stabilizing drive assembly includes a wall body 1901 fixed to the top of the rotating plate 18. The inner cavity wall on the back of the wall body 1901 is fixed with a drive motor 1902. The output shaft of the drive motor 1902 is fixed with a rotating rod 1903 rotationally connected with the wall body 1901. The outer side of the rotating rod 1903 is provided with two sections of threads with opposite rotation directions. A displacement block is threadedly connected to each section of thread on the rotating rod 1903. The inner cavity wall on the bottom of the wall body 1901 is fixed with a sliding seat. The bottom of each displacement block 1904 is fixed with a stabilizing block slidingly connected with the sliding seat. The top of each displacement block 1904 is fixed with a movable plate 1905. The top of the movable plate 1905 is fixed with an action block.

[0036] It should be further explained that the drive motor 1902 is energized to drive the rotating rod 1903 to rotate. The sliding seat and the stabilizing block are cooperatively arranged to realize the displacement of the displacement block 1904, thereby realizing the clamping and releasing of the sandblasting shell 20, and further facilitating the stable rust removal of the sandblasting shell 20.

[0037] Preferably, the top of the wall body 1901 is provided with a displacement opening. The movable plate 1905 movably passes through the displacement opening.

[0038] In the embodiment, the structure of the action block 1906 is beneficial to the fixation of the shell 20 and the improvement of the stability of the device. The displacement opening is beneficial to the stability of the displacement of the movable plate 1905, thereby improving the operation stability of the overall mechanism and the stability of the workpiece rust removal.

[0039] It can be seen that the sandblasting mechanism includes the sand container 4, the pressure booster 3 and the sand outlet pipe 5 which are communicatively arranged. The sand container 4 is used for containing the blasting material. The sand outlet pipe 5 penetrates into the inner cavity of the box body 1.

Specifically, the top of the box body 1 is fixed with the conveying plate 2. The top of the conveying plate 2 is fixed with the pressure booster 3. The top of the pressure booster 3 is fixed with the sand container 4. The bottom of the conveying plate 2 is fixed with the sand outlet pipe 5 which penetrates into the inner cavity of the box body 1.

[0040] The arrangement of the pressure booster 3 is beneficial to the delivery of the blasting material in the sand container 4, thereby facilitating the rust removal of the workpiece through the sand outlet pipe 5 and the implementation of the sandblasting rust removal work.

[0041] It can be seen that the dust falling mechanism comprises a water tank 6 fixed to the inner wall of the bottom of the box 1, a booster pump 7 fixed to the outer side of the water tank 6, a water delivery pipe 8 fixed to the left and right side walls of the box 1, the top of the water delivery pipe 8 extending into the inner cavity of the box 1, an adapter frame 9 fixed to the side of the top of the water delivery pipe 8 close to the water tank 6, and a water outlet pipe 10 fixed to the outer side of the adapter frame 9.

[0042] In this embodiment, the water in the water tank 6 is driven into the water delivery pipe 8 by the booster pump 7, and then the dust in the air is contacted by the spraying effect of the water outlet pipe 10, so that the dust is settled, which is beneficial to reduce the pollution degree of the device to the environment, thereby improving the use effect of the device.
