Vacuum adsorbing apparatus for fan positioning

Abstract

A vacuum adsorbing apparatus for fan positioning is provided, which includes a fixing frame and a vacuum aspirator. The fixing frame has a workpiece holder to provide close arrangement for the fan, and a through-hole connected with the vacuum aspirator is disposed in the workpiece holder corresponding to the arranged position of the fan, so as to pump out the air in the closed space between the through-hole and the fan when the vacuum aspirator actuates, thus positioning the fan on the fixing frame due to the suction force.

1 . A vacuum adsorbing apparatus for fan positioning, comprising:
 a fixing frame, having at least one workpiece holder on the fixing frame to provide close arrangement for at least one fan, wherein the workpiece holder has a through-hole and forms a closed space with the arranged fan; and   a vacuum aspirator, connected with the through-hole, and pumping out the air in the closed space when actuating, so as to form the state of fixing the fan to the fixing frame with vacuum suction force.   
   
   
       2 . The vacuum adsorbing apparatus for fan positioning as claimed in  claim 1 , wherein a washer is further provided on the workpiece holder at a position for the fan to be arranged, and the washer forms the closed space with the fan and the through-hole. 
   
   
       3 . The vacuum adsorbing apparatus for fan positioning as claimed in  claim 2 , wherein the washer is a rubber washer. 
   
   
       4 . The vacuum adsorbing apparatus for fan positioning as claimed in  claim 1 , wherein the workpiece holder is a groove matching with the fan to provide close arrangement for the fan. 
   
   
       5 . The vacuum adsorbing apparatus for fan positioning as claimed in  claim 4 , wherein a washer is further provided in the groove, and the washer forms the closed space with the fan and the through-hole. 
   
   
       6 . The vacuum adsorbing apparatus for fan positioning as claimed in  claim 5 , wherein the washer is a rubber washer. 
   
   
       7 . The vacuum adsorbing apparatus for fan positioning as claimed in  claim 1 , wherein the workpiece holder is of a planar shape, a washer is further provided between the workpiece holder and the fan, and the washer forms the closed space with the fan and the through-hole. 
   
   
       8 . The vacuum adsorbing apparatus for fan positioning as claimed in  claim 7 , wherein the washer is a rubber washer. 
   
   
       9 . The vacuum adsorbing apparatus for fan positioning as claimed in  claim 1 , wherein the vacuum aspirator is closely connected with the through-hole by an air pipe. 
   
   
       10 . The vacuum adsorbing apparatus for fan positioning as claimed in  claim 1 , wherein the through-holes are respectively arranged at central positions of the workpiece holders. 
   
   
       11 . The vacuum adsorbing apparatus for fan positioning as claimed in  claim 1 , wherein the through-holes are further provided with a thread respectively.
