[0002] Paint baking is a surface coating technology that cures paint at high temperatures, forming a protective layer that is highly resistant to friction, corrosion, and heat. This effectively extends the life of the workpiece and improves its appearance. During the paint baking process, a paint baking rack is also required to position the workpiece.

[0003] In the Chinese utility model patent with publication number CN216500178U, a reversible paint baking rack for paint baking processing is disclosed. The position of the support rod is adjusted until it is adjusted to the appropriate position, and the threaded pin is again inserted into the corresponding socket of the movable frame to fix the position of the support rod. Larger lacquerware can be clamped and fixed by multiple clamping components; the reversing function of the paint baking rack needs to be adjusted manually, but in the process of high-temperature paint baking, due to the high temperature, manual adjustment is more inconvenient and even prone to production accidents. Therefore, the device has the problem of low reversing efficiency, and in addition, when adjusting according to the size of the workpiece in the above-mentioned device, each support rod and positioning bar needs to be adjusted, which takes a long time to adjust and increases the workload.

[0004] Therefore, it is urgent to improve the existing reversible paint baking rack for paint baking processing, and provide a reversible paint baking rack for paint baking processing that can automatically reciprocate and flip. Utility Model Content

A servo motor is fixed to the front end outer wall of the left cross bar, and the output end of the servo motor is fixedly connected to the front end of the bidirectional screw. The limit rod is fixedly connected to the inner side of the right cross bar and extends in the front-to-back direction. The front and rear ends of the limit rod are respectively slidably connected to the right ends of the two load-bearing rods.

[0010] Preferably, the clamping assembly includes a plurality of concave blocks and fastening screws, wherein the plurality of concave blocks are arranged at equal intervals along the length direction of the bearing rod, the concave blocks and the fastening screws are in one-to-one correspondence and the two are threadedly connected.
