Description

Technical Field

[0001] The utility model relates to the field technology of air-floating table panel processing, in particular to a floating processing device for an air-floating table panel. Background Art

[0002] In the woodworking equipment industry, when turning multi-layer panels, a lot of manpower can be saved by operating on an air flotation table with rolling steel balls. The air flotation table is composed of supporting feet, an air storage box, an air flotation table panel, and a steel ball sleeve. The steel ball sleeve is connected to the holes of the air storage box and the air flotation table panel. If the holes do not match well, or if it causes air leakage in the air storage box, the labor-saving effect cannot be achieved. That is, the installation position of the air flotation balls (i.e., steel balls) of the air flotation table panel requires high processing accuracy, and improper processing can easily lead to air leakage.

[0003] The material of the air-floating table panel of the computer saw and six-sided drill of woodworking machinery equipment is usually high-pressure panel or PVC board, which cannot be processed on metal machine tools. The area of the air-floating table panel is large, and there is a difference in the thickness of the board surface, which leads to errors in the hole processing. At the same time, it is processed on a woodworking CNC machine tool. This type of machine tool adopts an adsorption processing method, which adsorbs the air-floating table panel on the worktable panel and then uses a chamfering processing tool to process multiple steel ball matching holes. There is a height difference in the adsorbed workbench. The CNC machine tool processing uses absolute coordinates, and its processing tool is fixed on the spindle. The size of the processed hole is set. Since it is impossible to eliminate the processing errors caused by the plate and the processing table, the processing accuracy of the processed steel ball matching holes is poor, and it is easy to have poor hole matching and cause air leakage.

[0004] Therefore, it is necessary to develop a new technology to solve the above problems. Utility Model Content
