[0001] This utility model relates to the field of metal surface coating technology, specifically to a uniform coating device for metal surfaces. Background Technology

[0002] Uniform coating equipment for metal surfaces is specialized equipment used to coat metal surfaces with paint to form a uniform coating. It is widely used in many fields such as automotive manufacturing, machining, and aerospace. However, existing uniform coating equipment for metal surfaces still has some shortcomings, such as:

[0003] The automated metal surface coating processing device described in Announcement No. CN221558809U has a problem: because the device does not have a workpiece clamping mechanism, it is difficult to ensure uniform rotation when processing tubular workpieces in actual use, resulting in inconsistent coating thickness on the workpiece surface and affecting subsequent processing. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a uniform coating device for metal surfaces, comprising a support frame, a spraying spindle, an exhaust pipe, a first motor, and a second spring;

[0006] An exhaust pipe is installed above the support frame;

[0007] A spraying spindle is mounted on the side of the support frame. A spray nozzle, a first motor, an eccentric disc, and an adjusting rail are arranged on the side of the spraying spindle. A transmission rod is arranged at the center line of the support frame. A limit ring, a second connecting rod, a rubber cone, a third connecting rod, and a second spring are installed above the transmission rod. A first spring and an extension block are installed on the side of the rubber cone. A second motor, a first gear, an adjusting pedal, and a first connecting rod are installed below the transmission rod.

[0008] As a preferred technical solution of this utility model, the exhaust pipe is fixedly connected at the bisecting position of the support frame. The exhaust pipe has a hexagonal structure, and a ring of threaded holes is evenly opened at the outlet position of the exhaust pipe. The air inlet of the exhaust pipe is conical, and the opening of the exhaust pipe has an inclined structure from bottom to top.

[0009] The above technical solution features a threaded interface at one end of the spraying spindle for connection to external spraying equipment, facilitating integration with the paint supply system. The spray nozzle employs an atomizing nozzle, enabling more uniform dispersion of paint on the metal surface and improving coating quality. Simultaneously, an adjustable workpiece fixing device is installed on the support frame to easily fix metal workpieces of different shapes and sizes, enhancing the equipment's versatility.

[0010] As a preferred technical solution of this utility model, the side of the support frame is rotatably connected to the spraying spindle, one end of the spraying spindle is provided with a threaded interface and connected to an external spraying device, the spray nozzle is fixedly connected to the midpoint of the spraying spindle, and the other end of the spraying spindle is fixedly connected to the adjustment rail, the side of the adjustment rail is slidably connected to the eccentric disk, the eccentric disk is fixedly connected to the output shaft of the first motor, and a bracket is provided below the first motor and connected to the support frame;
