Description

Rotary system for vertical film plating machine with blower shell Technical Field The invention relates to the technical field of coating equipment, in particular to a rotating system for a vertical coating machine with a blower shell. Background At present, the coating process of the blower housing mostly adopts vertical spraying equipment for surface treatment, and the equipment generally comprises a fixed spraying cavity, a rotary tool mechanism and a spraying nozzle. The working principle of the device is that the blower housing is fixed on a fixture head, the fixture is driven to rotate by a motor, and the surface of a workpiece is sprayed by the nozzle. However, in practical use, the existing vertical coating machine still has obvious defects in the aspects of tool posture switching, spray coating alignment and coating uniformity. Firstly, in the aspect of posture conversion between a tool and spraying plating, most of existing structures are single-shaft overturning or manual carrying, and the posture of the tool is switched depending on a mechanical arm or manual adjustment, so that automatic switching between horizontal clamping and vertical spraying plating cannot be realized. This not only results in low loading and unloading efficiency, but also easily causes alignment errors or surface pollution due to workpiece shake, affecting the quality and safety of spraying. In the aspects of workpiece deflection and spraying alignment control, most of devices adopt a rigid connection structure, and the bearing shaft can only realize the overturning of a fixed angle and cannot automatically fine-tune the opposite spray head according to the spraying position. In the spraying process, the workpiece is fixed in posture, so that spraying dead angles and local shielding phenomena are caused, and particularly in the peripheral and side wall areas of the blower shell, the thickness of the coating is unevenly distributed, and the appearance of the product and the adhesive force of the film layer are affected. In terms of rotary coating and film forming consistency, most of traditional rotary structures are driven by a single motor, and the clamping mechanism adopts a simple claw type structure, so that coaxiality and balance of workpieces are difficult to ensure. Because the rotation center is eccentric or the clamping is loose, centrifugal deviation is easy to generate in the spraying process, and the problems of uneven film thickness, over-plating at the edge, under-plating at the middle part and the like are caused. Meanwhile, most of spray heads of the existing spray coating device are arranged in a single plane for spraying, and the quality of the side wall coating of the workpiece is difficult to consider. In view of the above, the present invention provides a rotary system for a blower housing vertical coater, which solves the existing problems. Disclosure of Invention The present invention aims to solve one of the technical problems existing in the prior art or related technologies. The rotating system for the vertical film plating machine with the blower shell comprises a spraying box, a bearing assembly, a driving assembly and a driving assembly, wherein the spraying box is provided with a base and a spraying device on the upper surface and the lower surface of the spraying box respectively, the bearing assembly comprises a bearing shaft rod, a steering engine, a tool chuck and a ball head guide rod, the bearing shaft rod is rotationally connected with the base through a wing plate seat, the steering engine is fixed on a turning lug to drive the tool chuck to rotate, the driving assembly comprises a driving rod and a connecting rod group, two ends of the driving rod are respectively and movably connected with the base and the bearing shaft rod through a first turning shaft and a second turning shaft, one end of the connecting rod group is connected with the second turning shaft, and the other end of the connecting rod group is rotationally sleeved on the bearing shaft rod through an earmuff. The system drives the connecting rod group and the bearing shaft rod to turn over through the extension of the driving rod, so that the quick switching between the tool state and the spraying processing state is realized, and the steering engine drives the tool chuck to rotate during spraying, so that the atomization nozzle of the spraying device is aligned for spraying to form a uniform coating. Specifically, the structure forms a composite actuating mechanism of turnover and autorotation, the gesture is switched stably, the spraying alignment is accurate, and the coating consistency is high. The spraying device is further arranged in a preferred example, a base and a spraying device are respectively arranged on the upper surface and the lower surface of a spraying box, the bearing assembly comprises a bearing shaft rod, a steering engine, a tool chuck and a ball head guide rod movably connected with one end of th
