Abstract
Description
Technical Field
[0001] This utility model relates to the field of surface processing equipment technology, and in particular to a large-size, high-tonnage vertical turntable spraying device. Background Technology
[0002] In industrial production, large-tonnage vertical rotary table spraying equipment plays a vital role in numerous fields. With the continuous expansion of industrial production scale, the requirements for spraying quality and efficiency are also increasing. This equipment is widely used in industries such as automobile manufacturing, machining, and aerospace, providing high-quality spraying services for various large workpieces.
[0003] In existing technologies, spraying devices typically employ relatively simple mechanical structures. A common spraying method involves using a fixed spray gun to coat the workpiece, with the gun's position and angle remaining relatively constant. For example, in some traditional spraying equipment, the spray gun is mounted on a fixed bracket, limiting spraying to a limited area. The underlying principle is to utilize compressed air to propel paint from the spray gun, controlling the air pressure and paint flow rate to regulate the spraying effect.
[0004] However, existing technologies have a significant problem: when spraying large-tonnage workpieces, the fixed spray gun angle cannot be adjusted according to the shape and characteristics of the workpiece surface. This results in uneven coating coverage, with uneven spraying easily occurring at edges or corners, failing to achieve optimal coverage. This not only affects the aesthetics of the workpiece but may also reduce its protective performance and increase subsequent maintenance costs. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment: a large-size, high-tonnage vertical turntable spraying device, which includes a base 1, which serves as the basic support structure for the entire device. A housing 14 is fixedly connected to the upper surface of the base 1. The housing 14 not only protects the internal components but also provides a stable installation environment for the motor 23. The motor 23 is connected to a rotating rod 24 through its output end. After the motor 23 starts, it drives the rotating rod 24 to rotate, thereby realizing the rotation function of the turntable. A paint tank 7 is provided on one side of the outer wall of the base 1 for storing paint. The upper surface of the paint tank 7 is fixedly connected to the paint pipe 13, which is responsible for conveying the paint in the paint tank 7 to the spray gun 17. A connecting plate 6 is connected to one side of the outer wall of the paint tank 7. The connecting plate 6 connects to the electric push rod 8 and limits the movement of the sliding block 15. The output end of the electric push rod 8 pushes the sliding block 15 to move linearly along the direction of the connecting plate 6. The support block 9, fixedly connected to its lower surface, provides stable support for the electric push rod 8. A support plate 16, which is a support column 10, is fixedly connected to the upper surface of the sliding block 15. The support column 10 provides support, and an electric push rod 11 is fixedly connected to the upper surface of the support column 10. The output end of the electric push rod 11 is connected to a fixed column 12. An adjustment component is provided inside the fixed column 12, which includes a telescopic rod 22. One side of the outer wall of the telescopic rod 22 is fixedly connected to the inside of the fixed column 12, and a spring 21 is also fixedly connected to its outer wall. The spring 21 undergoes elastic deformation under the action of the telescopic rod 22. When the spray gun 17 is subjected to external force, the spring 21 buffers the spray gun 17 through its elastic force. A connecting plate is connected to one side of the outer wall of the spring 21. The connecting plate 20 provides an installation position for the spray gun 17. A limiting block 19 is connected to one side of the outer wall of the connecting plate 20. The limiting block 19 and the limiting plate 18 together limit the position of the spray gun 17 to prevent the spray gun 17 from shifting during the spraying process. A fixing column 12 is also fixedly connected to the upper surface of the base 1. A connecting column 3 is connected to the outer wall of the fixing column 12. A hydraulic rod 4 is connected to one side of the outer wall of the connecting column 3. The hydraulic rod 4 pushes the pressure plate 5 through its output end. The pressure plate 5 can fix the workpiece placed on the turntable to ensure that the workpiece remains stable on the turntable.
[0026] Reference Figure 1 and Figure 4The upper surface of the rotating rod 24 is fixedly connected to the chassis 26, the upper surface of the chassis 26 is fixedly connected to the fixed platform 29, the lower surface of the chassis 26 is connected to the insert 25, the insert 25 is fixedly connected to the inside of the insert 25, the bolt 27 is threadedly connected to the inside of the insert 25, and cooperates with the nut 28 to firmly fix the pin 30 to the insert 25. The upper surface of the pin 30 is fixedly connected to the lower surface of the fixed platform 29. The fixed platform 29 plays the role of supporting the workpiece, so that the workpiece can remain stable during the rotation of the turntable.
[0027] Working Principle: Using a large-size, high-tonnage vertical rotary table spraying device, the workpiece is first slowly hoisted onto the fixed platform 29 using lifting equipment. Care is taken to maintain the workpiece's balance and stability to prevent damage to both the workpiece and the equipment. The workpiece is aligned with the positioning device on the fixed platform 29 and gently placed on it. At this point, the hydraulic rod 4 is activated, providing power. The extension and retraction of the hydraulic rod 4 causes the pressure plate 5 to move vertically, thus firmly pressing the workpiece onto the fixed platform 29. This fixing method ensures the workpiece remains stable during the rotation of the fixed platform 29, preventing displacement due to centrifugal force or other external forces, thereby achieving the effect of fixing the workpiece securely on the fixed platform 29. Then, the paint in the paint tank 7 flows through the paint pipe 13 to the spray gun 17. Finally, the electric push rod 8 is activated. Pushing the sliding block 15 along the connecting plate 6 causes the support plate 16 on the sliding block 15 to move the support column 10 and the electric push rod 11, thereby adjusting the horizontal position of the spray gun 17. Activating the electric push rod 11 causes the fixed column 12 to slide along the inside of the support column 10, adjusting the vertical position of the spray gun 17. Pressing the spray gun 17 causes the spring 21 to contract, disengaging the limiting block 19 from the limiting plate 18, thus adjusting the angle of the spray gun 17. Adjusting the spray angle of the spray gun 17 allows it to form a suitable angle with the workpiece surface. Activating the motor 23 drives the rotating rod 24 to rotate, causing the fixed platform 29 to rotate, thus achieving the effect of spraying the workpiece.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
