Description

Technical Field

[0001] This utility model relates to the field of wheel painting technology, and in particular to a heavy-duty wheel painting device. Background Technology

[0002] Wheel hub painting is an important process for surface treatment of heavy vehicle components, directly affecting the product's corrosion resistance and appearance quality.

[0003] Existing wheel painting equipment mostly adopts a single-station design, which requires manual loading and unloading after painting is completed. This process wastes a lot of time and results in low utilization of the painting equipment. In particular, the long waiting time for the paint to cure after painting severely restricts the improvement of production efficiency. To solve the above problems, this application proposes a wheel painting device from Taiyuan Heavy Machinery Group. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a heavy-duty wheel painting device. By setting two three-jaw chucks, one can paint the heavy-duty wheels while the other can handle loading and unloading operations, thus avoiding downtime and improving processing efficiency. By setting an electric hot air blower, the paint can be dried, accelerating the drying process and further improving processing efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Preferably, the painting mechanism includes a material pump disposed on one side of the multi-axis manipulator, the material pump being fixedly connected to a first connecting pipe, a paint gun being fixedly connected to the top of the multi-axis manipulator, the first connecting pipe being fixedly connected to the paint gun, a bracket being fixedly connected to the top of the multi-axis manipulator, an air inlet pipe being fixedly connected to the bracket, an electric hot air blower being fixedly connected to the top of the multi-axis manipulator, the air inlet pipe being fixedly connected to the electric hot air blower, a spray nozzle being fixedly connected to the electric hot air blower, and a connecting mechanism being installed between the top of the paint gun and the spray nozzle.

[0008] Preferably, the spray booth has an inlet and outlet running through it, and the workbench is located in the middle of the inlet and outlet.

[0009] Preferably, a through opening is provided at the center of the heavy-duty wheel body, and the three-jaw chuck is located inside the through opening and abuts against the inner wall of the through opening.

[0010] Preferably, the two ends of the first connecting pipe are connected to the material pump and the paint gun, respectively.

[0011] Preferably, the connecting mechanism includes a column and a clamping block. The column is disposed on the top of the paint spray gun and fixedly connected thereto. The column is fixedly connected to the clamping block, and the clamping block is fixedly connected to the side wall of the spray nozzle.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The staff places the inner ring of the Taiyuan Heavy Machinery wheel body onto the three-jaw chuck. By moving the three movable jaws on the three-jaw chuck radially, the Taiyuan Heavy Machinery wheel body is clamped and positioned to ensure the stability of the Taiyuan Heavy Machinery wheel during subsequent painting and drying.

[0014] 2. Start the material pump. The material pump can inject paint into the paint gun through the first connecting pipe and finally spray it out through the paint gun to spray paint the end face of the rotating heavy wheel body.

[0015] 3. An electric hot air blower can inject outside air through the air intake pipe, and finally turn it into hot air, which is then sprayed out through the nozzle to dry the rotating heavy-duty wheel body, thus accelerating the drying of the paint, saving time, and improving processing efficiency.

[0016] In summary, by setting up two three-jaw chucks, one can be used for painting heavy-duty wheels, while the other can be used for loading and unloading, thus avoiding downtime and improving processing efficiency. By setting up an electric hot air blower, the paint can be dried, accelerating the drying process and further improving processing efficiency. Attached Figure Description
