Problems solved by technology

However, there are defects in the existing workpiece fixing methods. When the workpiece is clamped by a fixture, if the size of the workpiece is large, the middle part of the workpiece cannot be fixed, and the engraving quality of the workpiece will be seriously affected; During the method, the debris falling from the workpiece due to engraving will enter the adsorption hole under the adsorption of the vacuum pump, thereby blocking the adsorption pipeline and even causing the failure of the vacuum pump

Embodiment Construction

[0009] like figure 1 , 2 As shown, a vacuum adsorption device includes a workbench 10 with an adsorption surface 11 on the upper side, and a breathable plate 20 is laid on the adsorption surface 11 of the workbench 10 .

[0010] The setting of the air-permeable plate 20 not only realizes the adsorption and fixation of the workpiece, but also prevents debris from entering the adsorption holes on the lower side of the air-permeable plate 20, that is, the air-permeable plate 20 ensures the stable operation of the vacuum pump 30 and ensures the smooth progress of the engraving process .

[0011] As a preferred solution of the present invention, the air-permeable board 20 is a medium density board or a low density board.

[0012] Further, the density of the density board is 360~880kg / m 3 .

[0013] Further, the density of the density board is 360~550kg / m 3 , that is, the air-permeable board 20 is a low-density board. At this time, the air-permeable board 20 has low density, li...

Abstract

The invention relates to a vacuum adsorber belonging to the technical field of an engraving machine. The vacuum adsorber of the invention comprises a workbench, wherein an adsorbing surface is arranged at the upper side of the workbench, and a ventilating plate is laid on the adsorbing surface of the workbench. In the engraving process, a workpiece is laid at the upper side of the ventilating plate; when a vacuum pump works, the ventilating plate is tightly adsorbed on the adsorbing surface of the workbench; and because the ventilating plate has better air permeability, the workpiece is also tightly adsorbed on the ventilating plate, thereby realizing the purpose of adsorbing and fixing the workpiece. Meanwhile, because the workpiece and the surface of the workbench are separated by the ventilating plate, the falling scraps generated by engraving the workpiece can not enter adsorbing holes, thereby ensuring the smooth operation of the engraving process.

Description

technical field [0001] The invention belongs to the technical field of engraving machines, and in particular relates to a vacuum adsorption device. Background technique [0002] When engraving the workpiece, it is necessary to fix the workpiece on the worktable. There are two common methods for fixing the workpiece. One method is to clamp and fix the workpiece on the worktable through a clamp, and the other method is to fix the workpiece on the worktable. Adsorption holes are set on the upper surface of the worktable to form an adsorption surface. The adsorption holes are connected to the vacuum pump through the adsorption pipes arranged on the lower side of the worktable. When the vacuum pump is working during engraving, the workpiece will be adsorbed and fixed on the worktable. . However, there are defects in the existing workpiece fixing methods. When the workpiece is clamped by a fixture, if the workpiece size is large, the middle part of the workpiece cannot be fixed, ...
