Description

Technical Field

[0001] This utility model relates to the field of spray gun mobile equipment, and in particular to a spray gun lifting worktable based on lead screw and nut adjustment. Background Technology

[0002] In industrial production, the spray gun workbench is a key piece of equipment for achieving efficient and precise spraying operations, and its performance directly affects product quality and production efficiency. With the manufacturing industry's ever-increasing demands for product surface treatment, technological innovation in the spray gun workbench is particularly important.

[0003] Currently, most existing spray gun worktables employ relatively simple mechanical structures, commonly featuring a fixed-station design. The spray gun is mounted in a relatively fixed position, and its angle and position are manually adjusted to align with the workpiece for spraying. Technically, this relies heavily on worker experience, utilizing basic mechanical positioning devices to ensure the spray gun moves within a certain range. When dealing with complex-shaped workpieces, workers need to frequently and precisely adjust the spray gun's posture, a time-consuming and labor-intensive process that severely hinders production progress.

[0004] However, this traditional technical solution has obvious drawbacks. When spraying workpieces with complex outlines, the spray gun cannot automatically adjust its position and angle in real time according to the changes in the workpiece's outline. This makes it difficult to ensure that the spray gun maintains a constant distance and spraying angle from the workpiece surface. Consequently, the coating thickness and width become uneven across the workpiece surface during the actual spraying process, severely affecting the spraying quality, reducing the product's aesthetics and durability, and requiring extensive rework, further increasing production and time costs. To address these issues, a spray gun lifting platform based on screw and nut adjustment is proposed. Utility Model Content

This achieves the effect of keeping the spray gun and the outer contour of the workpiece moving together during spraying, maintaining a constant distance and a constant spraying angle, so that the thickness and width of the sprayed surface are uniform and firm. Compared with traditional equipment, the spraying quality and work efficiency are greatly improved. Attached Figure Description

During the height adjustment of the spray gun 22, motor 9 is started, and the output end of motor 9 drives the lead screw 10 to rotate, causing the base plate 11 to move up and down on the outer wall of the lead screw 10 and the fixed column 12. The sliding of the base plate 11 on the outer wall of the fixed column 12 limits the movement direction of the base plate 11. While moving, the base plate 11 is also moved by the lifting platform. 13 drives the connecting shell 14 to move up and down, achieving height adjustment of the spray gun 22. During the lateral movement of the spray gun 22, motor 15 is started, and the output end of motor 15 drives the belt drive mechanism 16 to rotate, causing the transmission plate 18 on the top of the connecting plate 17 to move laterally, and the slider 19 slides inside the connecting shell 14, limiting the movement direction of the transmission plate 18. At the same time, the bellows-type protective cover 23 protects the outer wall of the connecting shell 14, achieving lateral position adjustment of the spray gun 22. During the angle adjustment of the spray gun 22, motor 25 is started, and the output end of motor 25 drives the turntable 21 to rotate, and the rotating cylinder 20 provides support for the turntable 21, achieving angle adjustment of the spray gun 22. Finally, when spraying the workpiece, the spray gun 22 moves with the outer contour of the workpiece, maintaining a constant distance and a constant spraying angle, resulting in a uniform and firm coating thickness and width, improving the coating quality and work efficiency.
