Description

Technical Field

[0001] This utility model belongs to the field of spray painting technology, specifically relating to a spray painting device for general parts production. Background Technology

[0002] In the field of mechanical manufacturing, many common parts (such as bearing rings, gear blanks, flanges, etc.) are ring-shaped structures, and they often require painting during the production process to achieve the purposes of corrosion prevention, aesthetics, or marking. Currently, the painting of such ring-shaped parts is usually carried out manually after fixed clamping or by simple automated equipment.

[0003] Existing painting methods have the following main drawbacks: Paint damage issues: The most prominent problem is that regardless of whether an internal support or external clamping method is used, the clamping components will always be in contact with the part's surface. If the entire painting is completed in one clamping cycle, the clamping points will be covered, creating unpainted "dead zones" that require secondary repainting, resulting in low efficiency and uneven paint film. If the clamp is disassembled and flipped to paint another side after one side has been painted, the clamp will inevitably cause contact damage to the painted but not fully dry paint surface during re-clamping, resulting in defects such as indentations and scratches, which seriously affect the quality of the finished product.

[0004] Low level of automation and low production efficiency: Traditional painting processes often require multiple clamping, flipping and waiting for the paint to dry. The entire production process is discontinuous, with low automation and heavy reliance on manual operation, resulting in low production efficiency, which has become a bottleneck for large-scale production.

[0005] Environmental pollution and paint waste: Most existing equipment lacks an effective enclosed space. When spraying paint, paint droplets fly into the air, which not only wastes paint and increases production costs, but also pollutes the working environment and endangers the health of operators. Additional costs are required to treat waste gas and waste paint.

[0006] Coating uniformity issue: For coating the outer wall of ring-shaped parts, if the spray nozzle is fixed, the part itself needs to rotate to achieve uniform coverage. However, some existing simple devices lack a reliable rotation drive mechanism, or the rotation and clamping functions are not effectively integrated, resulting in uneven paint film thickness and affecting product performance.

[0008] A general-purpose parts manufacturing painting apparatus, comprising, Workbench; A clamping assembly is disposed on the outer wall of the worktable, wherein: the clamping assembly includes a protective shell, a lifting plate, a first nozzle, a rotating ring, a lower clamping rail, a first clamping claw, a second nozzle, an upper clamping rail, a second clamping claw, and a driving assembly. The lifting plate is slidably embedded in the top center of the outer wall of the protective shell. The first nozzle is rotatably embedded in the center opening of the inner wall of the lifting plate. The rotating ring is slidably embedded in the bottom center of the outer wall of the protective shell. The lower clamping rail is fixedly disposed in the top center of the outer wall of the rotating ring. The first clamping claw is slidably embedded in the outer wall of the lower clamping rail. The upper clamping rail is fixedly disposed in the top axis of the inner wall of the protective shell. The second clamping claw is slidably sleeved on the outer wall of the upper clamping rail. The second nozzle is fixedly disposed in the outer wall of the rotating ring. The driving assembly is disposed on the outer wall of the worktable.

[0009] Furthermore, the drive assembly includes a slide rail, a moving stage, a drive track, a first servo, a lead screw, a second servo, a driving gear, and a driven gear.

[0010] Furthermore, the slide rail is fixedly installed at the top of the outer wall of the worktable, the moving platform is slidably sleeved on the outer wall of the slide rail, the protective shell is fixedly installed at the top of the outer wall of the moving platform, the drive rail is fixedly installed at the top axis of the outer wall of the worktable, the first servo is fixedly installed at the center of the outer wall of one end of the drive rail, the lead screw is fixedly installed at the center of the outer wall of the output end of the first servo, and one end of the lead screw is threadedly connected to the opening of the outer wall of the moving platform.

[0011] Furthermore, the second servo is fixedly mounted on the inner wall of the protective shell by a bracket, the driving gear is fixedly mounted at the center of the outer wall of the output end of the second servo, the driven gear is fixedly mounted at the top of the outer wall of the rotating ring, and the driving gear and the driven gear are meshed together.

[0012] Furthermore, a drive cylinder is fixedly installed on the outer wall of the two protective shells, and a clamping cylinder is fixedly installed on the top of the outer wall of the rotating ring via a bracket.

[0013] Furthermore, the output end of the driving cylinder is fixedly disposed on the outer wall of the second clamping claw, and the output end of the clamping cylinder is fixedly disposed on the outer wall of the first clamping claw.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The protective shell creates a sealed painting space to prevent paint splatter. The first clamping claw initially clamps the part from the inner wall. A rotating ring drives the second spray head to achieve uniform painting of the outer wall of the part. After the paint on the outer wall dries, the drive cylinder controls the second clamping claw to clamp the dried part from the outer wall without damage. At the same time, the clamping cylinder releases the first clamping claw from the inner wall. Then, the lifting mechanism detaches the first clamping claw from the inner wall of the part. Finally, the first spray head completes the painting of the inner wall. This component realizes non-destructive switching between inner and outer wall painting of parts, avoids damage to the undried paint surface caused by clamping force, improves painting quality and production efficiency, and has a compact overall structure and high driving precision, making it suitable for automated painting operations of ring-shaped parts.
