Description

Technical Field

[0001] This utility model relates to the field of sandblasting machine technology, specifically to an adjustable sandblasting machine nozzle used in machining. Background Technology

[0002] Sandblasting can improve the fatigue resistance of workpieces, increase the adhesion between them and coatings, extend the durability of coatings, and also facilitate the leveling and decoration of paints. It removes impurities, discoloration and oxide layers from the surface, while roughening the surface of the medium, eliminating residual stress on the workpiece and increasing the surface hardness of the substrate.

[0003] Traditional sandblasting machines use a single nozzle for centralized sandblasting, lacking an adjustable sandblasting volume control device. When sandblasting is improperly operated or the sandblasting head moves, the thickness of the sandblasted material often varies. Furthermore, existing sandblasting machine nozzles do not have manual adjustment control or remote drive adjustment functions. Therefore, an adjustable sandblasting machine nozzle for machining is proposed. Summary of the Invention

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example

[0023] Please see Figures 1-5 This utility model provides a technical solution: an adjustable sandblasting nozzle for machining, comprising: nozzle body 1, mounting plate 4, adjustment mechanism and moving mechanism.

[0024] Inside the nozzle body 1, a ball valve ball 8 is installed. An adjusting rod 3 is fixedly connected to the outside of the ball valve ball 8, and the adjusting rod 3 is rotatably connected to the outer wall of the nozzle body 1. A first gear 10 is fixedly connected to the outside of the adjusting rod 3. A mounting plate 4 is fixedly connected to the nozzle body 1. An adjusting mechanism is mounted on the mounting plate 4 and is used to drive the first gear 10. A moving mechanism is mounted on the mounting plate 4 and is used to move the adjusting mechanism.

[0025] In this embodiment, specifically: when the through hole of the ball valve ball 8 is fully aligned with the internal channel of the nozzle body 1, the sandblasting channel is fully open and the sandblasting volume reaches its maximum.

[0026] In this embodiment, specifically: the adjustment mechanism includes a T-shaped block 12, which is slidably connected to the inside of the mounting plate 4. A housing 5 is fixedly connected to the T-shaped block 12. A motor 16 is installed inside the housing 5. A third gear 17 is fixedly connected to the end of the output shaft of the motor 16. A second gear 15 is rotatably connected inside the housing 5. The second gear 15 is meshed with the third gear 17 and is also meshed with the first gear 10.

[0027] In this embodiment, specifically: a controller 18 is installed inside the housing 5, and the controller 18 is electrically connected to the motor 16.

[0028] In this embodiment, specifically: the moving mechanism includes a slide groove 11, which is opened inside the mounting plate 4. The T-shaped block 12 is slidably connected to the inside of the slide groove 11. The outside of the mounting plate 4 is rotatably connected to a second threaded rod 14, which is threadedly connected to the T-shaped block 12. The mounting plate 4 is also threadedly connected to a first threaded rod 13.

[0029] In this embodiment, specifically: rotating the first threaded rod 13 causes the T-shaped block 12 to move, thereby causing the housing 5 to drive the second gear 15 away from the first gear 10. Manually rotating the adjusting rod 3 drives the ball valve ball 8, causing the through hole of the ball valve ball 8 to shift from the channel, reducing the cross-sectional area of ​​the channel and thus reducing the amount of sandblasting.

[0030] In this embodiment, specifically: a control signal is sent remotely to the controller 18, the controller 18 starts the motor 16, and its output shaft drives the third gear 17 to rotate. Since the third gear 17 meshes with the second gear 15, the power is transmitted to the second gear 15. The second gear 15 meshes with the first gear 10, and further transmits the power to the adjusting rod 3, which drives the ball valve ball 8 to rotate, thus realizing the remote adjustment of the sandblasting amount.

[0031] In this embodiment, specifically: in order to fill the gap between the ball valve ball 8 and the inner wall of the nozzle body 1, two rubber pads 9 are installed inside the nozzle body 1, and the two rubber pads 9 are located on both sides of the ball valve ball 8.

[0032] In this embodiment, specifically: in order to increase the sandblasting input channel, a secondary pipe 6 is connected to the outside of the nozzle body 1, and a cover 7 is threadedly connected to the outside of the secondary pipe 6. A pressure gauge 2 is also installed on the outside of the nozzle body 1. The pressure gauge 2 is used to monitor the sandblasting medium pressure inside the nozzle body 1 in real time.

[0033] Working principle: In use, rotating the first threaded rod 13 moves the T-block 12, thereby causing the housing 5 to drive the second gear 15 away from the first gear 10. Manually rotating the adjusting rod 3 drives the ball valve ball 8, causing the through hole of the ball valve ball 8 to shift from the channel, reducing the cross-sectional area of ​​the channel and thus reducing the sandblasting volume. A control signal is sent remotely to the controller 18, which starts the motor 16. Its output shaft drives the third gear 17 to rotate. Since the third gear 17 meshes with the second gear 15, power is transmitted to the second gear 15. The second gear 15 meshes with the first gear 10, further transmitting power to the adjusting rod 3, which drives the ball valve ball 8 to rotate, ultimately achieving remote adjustment of the sandblasting volume.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
