Description

Technical Field

[0001] This utility model relates to the field of rotary table technology, and in particular to a horizontal spray coating rotary table. Background Technology

[0002] With the continuous development of society and the economy, more and more mechanical equipment is being manufactured and widely used in agriculture, industry, and service industries. Mechanical equipment comes in a wide variety of types, and has undergone further innovation to meet different needs, playing an indispensable role in people's work and life; mechanical equipment is ubiquitous.

[0003] The internal structure of mechanical equipment is becoming increasingly complex, and its functions are becoming more and more diverse, and it is constantly being improved. Mechanical equipment generally includes drive devices, speed change devices, transmission devices, working devices, braking devices, protective devices, lubrication systems, cooling systems, etc., and different devices play different roles in mechanical equipment.

[0004] Spray coating is a metal surface processing method that uses a high-speed airflow to melt and spray molten coating material onto the surface of a workpiece, forming a coating layer. In existing technologies, when spray coating large cylindrical workpieces, the workpiece is typically vertically fixed on a positioning device, and the spraying device sprays the workpiece from top to bottom. The spraying device needs to spray the sides of the workpiece, and because of its size, the device must move and spray around its circumference multiple times, resulting in low production efficiency. Furthermore, maintaining a consistent distance between the spraying device and the curved surface of the workpiece during spraying can lead to deviations, resulting in uneven coating thickness (too thick or too thin), uneven paint distribution on the workpiece surface, sometimes causing color spots or even runs, leading to a high defect rate and inconvenience in production. The resulting product quality is poor and fails to meet current requirements. Therefore, it is necessary to study a new technical solution to improve the above-mentioned problems. Utility Model Content

[0005] In view of the above, this utility model addresses the shortcomings of existing technologies by providing a horizontal spraying rotary table. This table effectively solves the problems of existing technologies for spraying large cylindrical workpieces. Generally, the large cylindrical workpiece is vertically fixed on a positioning device, and the spraying device sprays it from top to bottom. The spraying device needs to spray the sides of the large cylindrical workpiece, which requires the spraying device to move and spray around its circumference multiple times due to the large size of the workpiece. This results in low production efficiency. Furthermore, the distance between the spraying device and the curved surface of the large cylindrical workpiece is difficult to maintain during spraying, leading to deviations and uneven coating thickness (too thick or too thin). Uneven coating distribution on the workpiece surface can sometimes cause color spots or even runs, resulting in a high defect rate and inconvenience to production, ultimately leading to poor product quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A horizontal spray coating rotary table includes a frame, a control box, a first rotary device, a transverse drive device, and a second rotary device. The frame extends laterally.

The first self-aligning roller bearings have an automatic self-aligning and deviation compensation function and a high load-bearing capacity. When the center of gravity of the workpiece changes or the force angle changes, the first self-aligning roller bearings can automatically adjust to ensure the smoothness of mechanical operation, smoother rotation, and extended service life of the equipment.

[0011] As a preferred embodiment, the second rotating device includes a second bracket and two second drive shafts. The second bracket is disposed at the other end of the frame, and the two second drive shafts are rotatably disposed on the second bracket. The two second rotating wheels are respectively disposed on the corresponding second drive shafts.

[0012] As a preferred embodiment, the second support is provided with four second bearing seats, arranged horizontally side by side with intervals between each pair of second bearing seats. Each second bearing seat is provided with a second through hole, and a second self-aligning roller bearing is provided in the second through hole. Each second drive shaft is rotatably mounted in the corresponding two second self-aligning roller bearings. The provision of the second self-aligning roller bearings helps to reduce friction.

[0014] As a preferred solution, the guide rail is fixedly mounted on the frame with screws, resulting in a stable connection structure that ensures smooth and safe operation, facilitates disassembly and maintenance, and brings convenience to production.

[0015] As a preferred embodiment, the lateral drive device includes two self-cleaning scrapers, which are disposed on the front and rear sides of the bottom surface of the second bracket. The two self-cleaning scrapers are respectively disposed on and adapted to the corresponding guide rails.

A second rotating device is positioned at the other end of the frame and driven laterally back and forth by a transverse drive mechanism. This second rotating device includes two second rotating wheels, arranged side-by-side and rotatably mounted on the frame. A placement position for placing the other end of the workpiece is formed between the two second rotating wheels. In the second placement position, this horizontal spraying rotary table uses a first rotating device to drive the workpiece and a second rotating device to rotate, allowing the spraying device to spray the entire workpiece in one direction, greatly improving production efficiency and reducing costs. Furthermore, the distance between the spraying device and the curved surface of the large cylindrical workpiece can be kept consistent during spraying, resulting in more uniform spraying, ensuring uniform coating thickness, guaranteeing quality, and preventing excessively thick or thin coatings, color spots, or runs, significantly reducing the defect rate, facilitating production, and improving the quality of sprayed products. The distance between the first and second rotating devices can be adjusted via a lateral drive device according to the length of different workpieces, making operation simple and meeting various needs.

A second rotating device is positioned at the other end of the frame and driven laterally back and forth by a transverse drive mechanism. This second rotating device includes two second rotating wheels, arranged side-by-side and rotatably mounted on the frame.
