Description

Technical Field

[0001] This utility model relates to the field of horn production technology, specifically to a spraying device for producing vehicle-mounted horns. Background Technology

[0002] A car horn is an audio signal device used in a car. During driving, the driver emits necessary audio signals as needed and in accordance with regulations to warn pedestrians and attract the attention of other vehicles, thus ensuring traffic safety. The car horn cover is an accessory on the car horn that serves to protect it from dust. When manufacturing the horn cover, it needs to be painted.

[0003] In existing technology, spraying equipment typically consists of a spray gun, a spray chamber, a clamping mechanism, and a transmission mechanism. When spraying horns, the horn is placed in the spray chamber, and the motor in the clamping mechanism drives the clamping plate to hold and fix the horn. The motor in the transmission mechanism then drives the spray gun to the appropriate position to perform the spraying operation. However, existing technology cannot clamp horns of different sizes, and the angle of the spray head cannot be adjusted during the spraying process, resulting in inconsistent spraying quality.

[0004] To address the aforementioned problems, existing technologies provide a solution. For example, patent publication number CN222369426U discloses a vehicle horn production spraying device, including a workbench; a hydraulic press is fixed to one end of the workbench, a transmission mechanism is mounted on the top of the hydraulic press, a mounting base is fixed below the transmission mechanism, and an adjustment mechanism is mounted below the mounting base; by setting the adjustment mechanism, the hydraulic press is started, and the horizontal plate in the transmission mechanism is adjusted to a suitable height, so that the spraying head below the adjustment mechanism in the mounting base at the bottom of the horizontal plate is adjusted to a suitable height for spraying. When the processing angle needs to be adjusted, the motor in the adjustment mechanism is started, so that the motor... The rotating shaft drives the gear to rotate. Through the meshing of the gear and the half-gear ring, the half-gear ring drives the swing rod on one side to move. Under the limit of the rotating rod fixed on the inner wall of the mounting base, the swing rod drives the bottom spray head to adjust the angle, making the spraying more comprehensive and improving the quality of the horn spraying. Although the existing device can adjust the spray head angle to spray various parts of the horn, when spraying smaller horns, the high pressure of the spray head can easily cause the horn to shift under the high pressure of the paint, resulting in uneven spraying on the horn surface and reducing the spraying effect of the horn.

[0005] To address this, a spraying device for the production of vehicle-mounted horns is proposed. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the embodiments described below are only some embodiments of the present utility model, and not all of them. If other embodiments are obtained by those skilled in the art without creative effort, they shall fall within the protection scope of the present utility model.

[0023] Reference Figures 1 to 4A vehicle-mounted horn production spraying device includes a support leg 1, a support base 2, and a mounting base 3. It also includes a servo motor 4, a drive mechanism 5, a spray head 6, a rotating rod 7, an adjusting mechanism 8, a connecting plate 9, a telescopic rod 10, and a clamping plate 11. The servo motor 4 is connected to the mounting base 3, the drive mechanism 5 is connected to the servo motor 4, the spray head 6 and the rotating rod 7 are both connected to the drive mechanism 5, the adjusting mechanism 8 is connected to the rotating rod 7, the connecting plate 9 is connected to the adjusting mechanism 8, the telescopic rod 10 is connected to the connecting plate 9, and the clamping plate 11 is connected to the telescopic rod 10. The clamping plate 11 is arc-shaped, with an arc-shaped portion 12 at its top. When the servo motor 4 starts, the drive mechanism 5 controls the spray head 6 to rotate 360 ​​degrees, and simultaneously controls the adjusting mechanism 8 to operate via the rotating rod 7. When the adjusting mechanism 8 operates, the connecting plate 9 controls the clamping plate 11 to press against the inner wall of the horn via the telescopic rod 10.

[0024] As one embodiment of this utility model, refer to Figure 2 and Figure 3 The drive mechanism 5 includes a rotating shaft 51, a main turntable 52, an L-shaped frame 53, a distribution pipe 54, a transmission belt 55, and a secondary turntable 56. The rotating shaft 51 is connected to the servo motor 4. The main turntable 52 and the L-shaped frame 53 are both connected to the rotating shaft 51. The distribution pipe 54 is connected to the L-shaped frame 53. The transmission belt 55 is connected to the main turntable 52, and the secondary turntable 56 is connected to the transmission belt 55. The main turntable 52 and the secondary turntable 56 have the same diameter, and the axes of the main turntable 52 and the secondary turntable 56 coincide with the center line of the mounting base 3. Through the above arrangement, the device can be made more stable. The frame 53 includes a horizontal part 531 and a vertical part 532. The nozzles 6 are respectively installed on the horizontal part 531 and the vertical part 532. The spacing between the nozzles 6 on the horizontal part 531 is smaller than the spacing between the nozzles 6 on the vertical part 532. With the above setting, the spraying of the outward side of the vehicle speaker can be more uniform, and the area of ​​the vehicle speaker that is not sprayed can be avoided. The length of the horizontal part 531 is greater than the spacing between the two clamps 11. With the above setting, it can smoothly move around the speaker when spraying speakers of different sizes, thereby achieving 360-degree spraying of the speaker.

[0025] As one embodiment of this utility model, refer to Figure 3 and Figure 4The adjusting mechanism 8 includes a main bevel gear 81, a secondary bevel gear 82, a reciprocating screw 83, and a threaded block 84. The main bevel gear 81 is connected to the rotating rod 7, the secondary bevel gear 82 is engaged with the main bevel gear 81, the reciprocating screw 83 is connected to the secondary bevel gear 82, the threaded block 84 is connected to the reciprocating screw 83, and the clamping plate 11 is connected to the threaded block 84. The gear ratio between the secondary bevel gear 82 and the main bevel gear 81 is 1:5-1:10. Through the above settings, the secondary bevel gear 82 can rotate at a faster speed, so that the two connecting plates 9 can be quickly separated when the L-shaped frame 53 drives the diverter pipe 54 to rotate one revolution, thereby quickly clamping and positioning the horn. The edge of the main bevel gear 81 is flush with one end of the threaded groove of the reciprocating screw 83. Through the above settings, the main bevel gear 81 can be prevented from obstructing the horn, and at the same time, it can avoid obstructing the movement of the L-shaped frame 53.

[0026] Working principle: In use, the user connects the transducer to the external paint, places the vehicle horn on the support 2, and then starts the servo motor 4. The servo motor 4 drives the main turntable 52 to rotate via the rotating shaft 51. When the main turntable 52 rotates, it drives the distributor pipe 54 to rotate 360 ​​degrees via the L-shaped bracket 53. At the same time, it drives the secondary turntable 56 to rotate via the transmission belt 55. When the secondary turntable 56 rotates, it drives the main bevel gear 81 to rotate via the rotating rod 7. When the main bevel gear 81 rotates, it drives the forward and reverse directions via the secondary bevel gear 82. When the reciprocating screw 83 rotates, it can drive the connecting plate 9 to move in the opposite direction through the threaded block 84. When the threaded block 84 moves, it can drive the clamping plate 11 to move through the telescopic rod 10. When the clamping plate 11 moves, it can fit against the inner wall of the speaker. At the same time, as the connecting plate 9 gradually separates, it squeezes the telescopic rod 10. Under the pressure, the clamping plate 11 can gradually tighten its fit against the inner wall of the speaker. While the splitter pipe 54 rotates with the L-shaped frame 53, it can spray paint onto the outer wall of the speaker through the spray nozzle 6 to achieve the spraying of the speaker.
