Spraying device for inner surfaces of pipe fittings

Abstract

The invention discloses a spraying device for inner surfaces of pipe fittings, which belongs to the technical field of spraying devices. The device comprises a lower cabinet body, a pipe fitting speed adjusting mechanism and a spraying mechanism; the pipe fitting speed adjusting mechanism and the spraying mechanism are located above the lower cabinet body; the pipe fitting speed adjusting mechanism comprises an electric motor mounting plate, a first drive device, a driving belt wheel, a synchronous belt, a driven belt wheel, a driving roller, a workpiece and a driven roller; and the spraying mechanism comprises an electric cylinder, a sliding block, a bottom plate, a lifting rack, a lead screw, a hand wheel, a slide bearing and a spray gun. Rotation of the workpiece is realized by using the pipe fitting speed adjusting mechanism, continuous and uniform spraying of an inner pipe surface of the workpiece is finished by the spraying mechanism, and the pipe fittings of various models can be machined by collaboration and coordination of the pipe fitting speed adjusting mechanism and the spraying mechanism. The spraying device can effectively reduce dependency on manual operation and is high in spraying quality, and meanwhile, the device is simple and light in structure, higher in efficiency and precision and lower in cost, and meets multiple machining requirements.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of spraying equipment, and in particular relates to a spraying device for the inner surface of pipe fittings. [0003] Background technique: [0004] In today's industrial production, it is often necessary to spray the surface of the pipe fittings used to increase the rust resistance and airtightness of the pipe fittings, and even increase the strength, making the pipe fittings more durable, especially the inner surface of the pipe fittings. High-precision spraying of the inner surface of pipe fittings is a difficult problem faced by small and medium-sized enterprises. Traditional manual methods cannot complete spraying with high precision, and high-precision and intelligent equipment is too expensive. Therefore, a simple but high-precision The device has become an urgent need for many small and medium-sized enterprises. The device has a simple structure and a clear principle, and can complete the sp...
