Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, specifically to a painting device for automotive parts. Background Technology

[0002] Automotive spare parts (SMPs) are the various units that make up the whole automotive parts processing, as well as the products that serve automotive parts processing. Before use, automotive spare parts usually need to be processed and painted to prevent internal oxidation and rust, thus extending the service life of automotive spare parts.

[0003] The CN 212263693 U publication discloses a painting device for automotive parts. By setting up a painting mechanism and an electric push rod, a movable block can be disassembled and its position adjusted by rotating a butterfly knob to adjust the position and angle of the spray nozzle. By controlling the electric push rod to drive the painting mechanism to rise and fall, the height of the spray nozzle can be adjusted. This solves the problem that traditional automotive parts painting devices cannot adjust the position and angle of the spray nozzle according to the shape of the automotive parts, resulting in some automotive parts needing to be painted multiple times. It achieves the effect of being applicable to automotive parts of different shapes and improving work efficiency.

[0004] The painting device for automotive parts can paint automotive parts through its internal painting mechanism. However, the painting mechanism cannot move back and forth, resulting in uneven paint application on the surface of the automotive parts during the painting process, which makes it inconvenient to use. Therefore, it needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide a painting apparatus for automotive parts to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a painting device for automotive parts, including a spray box, a reciprocating spraying mechanism fixedly connected to the top of the spray box, a drying mechanism fixedly connected to the top of the spray box, and a rotating moving mechanism fixedly connected to the bottom of the spray box. The reciprocating spraying mechanism includes a first motor, which is fixedly connected to the top of the spraying box. A rotating shaft is fixedly connected to the bottom of the first motor, and a load-bearing plate is rotatably connected to the bottom of the rotating shaft. A load-bearing rod is fixedly connected to the top center of the load-bearing plate, and the top of the load-bearing rod is fixedly connected to the top of the inside of the spraying box. A sprocket is fixedly connected to the periphery of the rotating shaft, and a chain is meshed around the periphery of the sprocket. A first limiting rod is fixedly connected to the top of the chain, and an arc-shaped block is fixedly connected to the top of the first limiting rod. The arc-shaped block is slidably connected inside the spraying box. The first limiting rod and the arc-shaped block can support and limit the chain, making the chain rotate more stably when pulled by external force.

[0007] According to the above technical solution, a short rod is fixedly connected to the bottom of the chain, a rotating plate is fixedly connected to the bottom of the short rod, a first fixed rod is rotatably connected inside the rotating plate, and a sliding block is fixedly connected to the bottom of the first fixed rod. When the chain moves, it can drive the rotating plate to rotate through the short rod, so that the rotating plate can drive the sliding block to move through the first fixed rod.

[0008] According to the above technical solution, a connecting rod is fixedly connected to the bottom of the sliding block, a sprayer is fixedly connected to the bottom of the connecting rod, and a spray pipe is fixedly connected to the bottom of the sprayer. When the sliding block moves, it can drive the nozzle to move through the connecting rod, so that the nozzle can spray the automotive parts through the spray pipe.

[0009] According to the above technical solution, the rotating moving mechanism includes a second motor, which is fixedly connected to the right side of the spray box. A first threaded rod is fixedly connected to the left side of the second motor. The left side of the first threaded rod is rotatably connected to the left side inside the spray box. A threaded block is threadedly connected to the outer periphery of the first threaded rod. A fixed plate is fixedly connected to the top of the threaded block. A slider is slidably connected inside the fixed plate. A second limiting rod is fixedly connected to the top of the slider. A rotating plate is fixedly connected to the top of the second limiting rod. A fixed cylinder is fixedly connected to the top of the rotating plate. When the second motor drives the threaded block to move through the first threaded rod, it can drive the fixed plate to move, allowing the fixed plate to move to the opening of the spray box, which facilitates the operator to clamp and fix the automotive parts.

[0010] According to the above technical solution, an electric telescopic rod is fixedly connected to the front and rear sides of the fixed cylinder. A movable plate is fixedly connected to the side of the electric telescopic rod away from the fixed cylinder. The bottom of the movable plate is slidably connected to the top of the rotating plate, and a fixed plate is fixedly connected to the top of the rotating plate. The electric telescopic rod can drive the movable plate to move, so that the movable plate can clamp the automotive parts. This makes the device suitable for clamping automotive parts of different sizes.

[0011] According to the above technical solution, a linkage rod is fixedly connected to the bottom of the rotating plate, and the bottom of the linkage rod is rotatably connected to the top of the fixed disk. A worm gear is fixedly connected to the periphery of the linkage rod, and a worm is meshed on the right side of the worm gear. A third motor is fixedly connected to the front of the worm, and the third motor is fixedly connected to the top of the fixed disk. The worm gear and the worm have a self-locking effect, so that the rotating plate is not easily rotated when the device is impacted, and the worm can drive the worm gear to rotate, so that the worm gear can drive the rotating plate to rotate through the linkage rod, so that the rotating plate can drive the automotive parts to rotate.

[0012] According to the above technical solution, the drying mechanism includes a fixed frame, which is fixedly connected to the top of the spray box. A fourth motor is fixedly connected to the right side inside the fixed frame, and a second threaded rod is fixedly connected to the left side of the fourth motor. The left side of the second threaded rod is rotatably connected to the left side inside the fixed frame. A vent plate is threadedly connected to the outer periphery of the second threaded rod, and a fan is fixedly connected to the bottom of the vent plate. The fan can dry the sprayed automotive parts.

[0013] According to the above technical solution, a second fixing rod is slidably connected inside the side of the breathable plate away from the second threaded rod. The second fixing rod is fixedly connected inside the fixing frame. The second fixing rod can limit the movement of the breathable plate, making the breathable plate more stable when it moves.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: The painting device for automotive parts uses a first motor mounted on a reciprocating spraying mechanism to drive a rotating shaft, which in turn drives a sprocket, which in turn drives a chain, which in turn drives a rotating plate via a short rod. The rotating plate then drives a sliding block via a first fixed rod, which in turn drives a sprayer via a connecting rod, allowing the sprayer to paint the fixed automotive parts.

[0015] This painting device for automotive parts uses a second motor mounted on a rotary moving mechanism to drive a first threaded rod to rotate. This first threaded rod then moves a threaded block, which in turn moves a fixed plate. The fixed plate, via a slider and a load-bearing rod, moves a rotating plate, allowing workers to easily clamp and fix the automotive parts. A third motor drives a worm gear to rotate a worm wheel, which in turn, via a linkage rod, rotates the rotating plate. This allows the painted automotive parts to be rotated and repositioned, eventually reaching the drying area.

[0016] This painting device for automotive parts uses a fourth motor on the drying mechanism to drive a second threaded rod to rotate. This second threaded rod then moves a vent plate, which in turn drives a fan to dry the automotive parts after the spray nozzle has passed through. A second fixing rod limits the movement of the vent plate, making it more stable during movement. Attached Figure Description

The fixed plate 306, through the slider 34 and the second limit rod 35, drives the rotating plate 36 to move. The first motor 21 is activated, causing it to drive the sprocket 205 to rotate through the shaft 22. The sprocket 205, through the chain 24, drives the short rod 201 to move. When the chain 24 drives the short rod 201 to move... When the chain 24 reaches the edge of the sprocket 205, it can drive the rotating plate 29 to rotate via the short rod 201.

This allows the painted automotive parts on the top of the rotating plate 36 to move and to the bottom of the fixed frame 46. The fourth motor 41 is then activated, driving the vent plate 43 to move via the second threaded rod 45. This allows the vent plate 43 to dry the painted automotive parts via the fan 42, making them easier to use.
