Abstract

The invention discloses a high-gloss low-film-thickness aluminum alloy hub spraying device, and relates to the related technical field of automobile hub spraying, the high-gloss low-film-thickness aluminum alloy hub spraying device comprises a bottom plate, the upper surface of the bottom plate is movably connected with a conveying belt, the upper surface of the conveying belt is symmetrically and fixedly connected with mounting plates, and the upper surface of one side of each mounting plate is provided with a movable groove. The invention further discloses a spraying process of the high-gloss low-film-thickness aluminum alloy hub spraying device. The spraying process comprises the steps of A, automobile hub surface pretreatment, B, preparation before automobile hub paint spraying, C, automobile hub surface retreatment, D, automobile hub mounting and fixing, E, automobile hub surface paint spraying, F, automobile hub surface finish paint spraying and G, automobile hub surface gloss oil protective paint spraying. The bearing plate slides into the inner wall of the mounting plate, and the rotary knob is rotated to drive the clamping plate to move towards the mounting plate, so that the hub can be quickly mounted and fixed, the dismounting and mounting convenience degree of the hub can be effectively improved, and the paint spraying operation efficiency of the hub is improved.

Description

technical field [0001] The invention relates to the related technical field of automobile wheel hub spraying, in particular to a high gloss and low film thickness aluminum alloy wheel hub spraying process and a spraying device thereof. Background technique [0002] The hub of an automobile is the part where the axle is installed in the center of the wheel. After die-casting, it generally needs to be painted and other post-processing. The hub is large and heavy, and its shape is cylindrical. The handling of personnel is extremely difficult. The existing method is generally direct The surface of the automobile wheel is sprayed after being clamped, which not only has a poor painting effect but also increases the difficulty of operation. [0003] In China's invention patent application number: CN202010239204.6, a wheel paint spraying device is disclosed. Although the wheel paint spraying device can rotate the fixed wheel hub, it can simultaneously spray the two sides of the whee...
