Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that described embodiment is part of the embodiment of the present utility model, rather than is all implemented
Example.Based on the embodiment in the utility model, those of ordinary skill in the art institute on the premise of creative work is not made
The every other embodiment obtained, it should all belong to the scope of the utility model protection.
Embodiment
A kind of slim self-centering vacuum clamping device for having hole non-metal workpiece of the utility model is as shown in figure 1, described
Device include top vacuum chuck 3, lower vacuum chuck 2 and internal expanding closing sleeve component, described top vacuum chuck 3 with
Lower vacuum chuck 2 is fixedly connected, and described internal expanding closing sleeve component is installed on top vacuum chuck center；There is hole by slim
Non-metal workpiece is placed on the vacuum chuck of top, and described internal expanding closing sleeve component is embedded in the centre bore position of part, adjustment
