[0002] Automobile panel molds refer to steel panels for automobiles, also known as automobile panels. The appearance of automobile panels is mostly regular rectangular plates. Painting robots, also known as spray robots, are industrial robots that can automatically spray paint. They can effectively improve the efficiency of spraying, and thus improve production efficiency, greatly saving labor costs and time costs. In order to facilitate automated control and reduce the impact on operators, automobile panels are generally sprayed by spray robot painting arms.

[0003] In the related art, in order to protect the health of personnel, robots are used to replace manual work. For example, the patent with the prior art publication number CN218078767U provides a brushing device for a painting robot, including a brushing assembly matching the painting robot, the brushing assembly includes a base fixed to the front end of the manipulator of the painting robot, and a brush fixed on the base; wherein, the base is composed of a connecting plate and a cantilever arm integrally erected on the connecting plate, the connecting plate is provided with a mounting hole, and the connecting plate is fixed to the front end of the manipulator through the mounting hole and a connecting screw passing through the mounting hole.

[0004] Although the above-mentioned prior art solutions can achieve high-quality painting of complex mechanical products and protect the health of painting workers by setting up a brush coating assembly, the existing auxiliary painting arm for painting robots, during the rotation process, the nozzle and the robot arm body are in close contact, which easily generates friction, causing the outer skin of the nozzle to be severely worn, and the painting arm cannot clamp nozzle devices of different diameters as needed, so the applicability is relatively low.

[0005] In view of this, we propose an auxiliary painting arm for an automobile panel painting robot. Utility Model Content

[0030] Embodiment 2

[0031] The auxiliary coating arm for the automobile panel coating robot proposed in the utility model is compared with the first embodiment. Figure 4 The clamping assembly 300 includes a track 312, a moving block 311 is symmetrically slidably arranged inside the track 312, a clamping plate 316 is arranged at one end of the moving block 311, a clamping pad 313 is arranged on the side where the two clamping plates 316 are close to each other, and a limit assembly is arranged on the side where the clamping plates 316 are far from the track 312, and a bidirectional threaded rod 310 is rotatably arranged inside the track 312, and the threads on both sides of the bidirectional threaded rod 310 are opposite to each other with the center as the base point, and the threads of the bidirectional threaded rod 310 pass through the inside of the two moving blocks 311.
