For convenience of control, the auxiliary processing equipment for hub spraying further comprises a controller, and the controller is respectively in signal connection with the cylinders of the lifting mechanism 34, the translation driving assembly 12, the two-axis translation driving assembly 42, the image processing device and the clamping jaw 43.
In order to facilitate the transportation of the hub 70, the auxiliary processing equipment for spraying the hub further comprises a transportation mechanism 60 for transporting the hub 70, the transportation mechanism 60 is arranged on one side of the base 10, and the two-axis translation driving assembly 42 drives the clamping jaw 43 to move back and forth between the transportation mechanism 60 and the base 10, so that the clamping device 40 can clamp the hub 70 onto the base 10 from the transportation mechanism 60, automation is realized, the labor is reduced, and the production efficiency is improved. The conveying mechanism 60 may employ a chain scraper conveyor, a roller conveyor, or the like.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
