Description

Segmented vacuum adsorption table top and woodworking processing center made of the table top

technical field

The utility model relates to the technology in the field of engraving machines, in particular to a segmented vacuum adsorption table and a woodworking processing center made of the table. the

Background technique

When engraving, drilling, cutting, etc. the workpiece (the workpiece of the plate machining center, especially the machining center workpiece of the woodworking industry, soft metal, flower board, and PVC board), it is necessary to fix the workpiece on the workbench. There are two ways to fix the workpiece. One method is to clamp and fix the workpiece on the worktable through the fixture. The other method is to open air holes on the worktable to make the surface of the workbench form an adsorption surface. The air holes are set on the worktable. The adsorption pipeline under the table is connected with the vacuum pump. During engraving, drilling and cutting, when the vacuum pump works, the workpiece is adsorbed and fixed on the worktable. the

However, existing workpiece fixing methods all have defects. When the workpiece is clamped by a fixture, if the workpiece size is large, the middle part of the workpiece will not be fixed, and the engraving, drilling and cutting quality of the workpiece will be seriously affected. When using the traditional adsorption fixing method, since the adsorption surface is integrally connected, if you want to adsorb workpieces smaller than the adsorption surface, you need to add sealing strips to block the ventilation grooves around the workpiece to solve the adsorption problem of such workpieces; but For workpieces with extremely small surfaces, even if sealing strips are added, the adsorption effect is usually not ideal, resulting in the inability to carry out engraving operations; and, for workpieces of different sizes processed each time, the sealing strips need to be disassembled and installed corresponding to each time to enclose A vacuum adsorption area suitable for the size of the workpiece is formed, and multiple disassembly and installation make the processing of the workpiece more time-consuming and labor-intensive, which brings inconvenience to production. the
