Description

Technical Field

[0001] The utility model relates to the technical field of automobile spraying line suspension, in particular to a spraying line suspension mechanism. Background Art

[0002] A paint spraying line is an automatic or semi-automatic coating equipment. It can put the workpiece to be painted into the line, and then go through multiple coating processes to finally complete the coating. The paint spraying line has the advantages of high efficiency, energy saving, and environmental protection. It can be widely used in automobiles, machinery, electronics, building materials and other fields. The core component of the paint spraying line is the spraying equipment, which can be customized according to different coating requirements, including spray guns, nozzles, pumps, pipes, etc. The spraying equipment can evenly spray the paint on the surface of the workpiece to be painted to form a uniform coating. The advantages of the paint spraying line include: it can greatly improve the coating efficiency, reduce labor costs, and the coating quality is stable and reliable, which can meet various high-quality coating requirements.

[0003] When spraying workpieces on existing spray lines, it is necessary to spray both the front and back sides of the workpieces. Generally, one side is sprayed and then manually turned over for re-spraying. There are problems of low work efficiency and poor spraying effect. In addition, during the suspension spraying work, due to the influence of factors such as hangers and hooks when the transmission chain is driven, the workpiece will shake, resulting in inconsistent positions of each workpiece passing through the spray gun, thereby affecting the spray thickness and consistency, and affecting product performance. For this reason, we propose a spray line suspension mechanism. Utility Model Content

[0023] In specific implementation, the rotary driver 8 adopts a slewing driver, with a slewing bearing (drive motor) as a transmission follower and a mechanism attachment. The active part, the drive source and the cover are attached to one of the inner and outer circles of the slewing bearing. At this time, the rotary driver 8 drives the gear seat 7 to rotate on the roller gear bar inside the slide rail 6, thereby generating displacement, so that the spray gun 9 moves at a uniform speed inside the slide rail 6, so as to perform stable and uniform spraying work.

[0024] A suspension ball 1301 is movably connected between the movable wheel 1202 and the transmission wheel 1203 , and the dimensions of the outer surfaces of the movable wheel 1202 and the transmission wheel 1203 match the dimensions of the outer surface of the suspension ball 1301 .

[0025] When implementing, follow these steps:

[0026] 1) Assemble the workpiece first, open the dustproof door 2, hang the automobile workpiece to be processed on the suspension bracket 1306, and then fix the second fastener 1304 with the first fastener 1303, and finally open the transmission cabin 11, push the suspension ball 1301 between the transmission wheel 1203 and the movable wheel 1202, and then thread the main frame 1302 and the suspension ball 1301, and the assembly is completed;

[0030] Furthermore, by setting up the suspension structure 13 and coordinating the slide rail 6 and the rotation driver 8, during the spraying process, when multiple workpieces to be sprayed are suspended on the workpiece suspension hanger, the spray guns 9 on both sides can be used to operate simultaneously to achieve the effect of spraying the front and back sides of the workpiece at the same time, which can greatly shorten the spraying time and improve the workpiece spraying efficiency. In addition, there is no need to manually adjust the spraying position of the workpiece, and the operation of rotating the workpiece during the spraying process is eliminated, which saves time and effort and has good practicality.
