Benefits of technology

The present invention provides a fan positioning apparatus that can quickly fix the fan to a given position without using ribs or filling wax or lime, thereby decreasing the pre-operation time of fan molding and effectively reducing the positioning costs during fan positioning. The apparatus includes a fan, a fixing frame, and a vacuum aspirator. The fan is placed on the workpiece holder, and the vacuum aspirator generates a powerful suction force, thus facilitating the operation of molding the fan and finely tuning the fan blades. After finishing the molding or the fine tune of the blades, the finished product of the fan can be taken off as long as the vacuum aspirator is switched-off. The apparatus has low cost and saves time and costs during the pre-operation. It also allows for a direct molding operation without using wax, lime, or ribs, and reduces the need for manual trimming of the fan blades after finishing molding.

Problems solved by technology

Conventionally, the most important moment during CNC's manufacturing of fan lies in the molding and cutting of the fan, since it is the last stage before having the product finished, and all previous efforts will go wasted if we fail to handle it well.
(1) The disadvantage of fixing the fan by ribs is the need to trim the fan blade after its molding, however, since the trimming has to be done manually, the damage of fan blade due to overexerting occurs frequently.
Still, the fan cannot be effectively fixed by filling wax or utilizing lime during its molding operation, so the swaying or shifting of fan occurs frequently, which therefore leads to the failure of the molding operation of the fan.

Embodiment Construction

[0018]As shown in FIG. 1, it is a basic architectural schematic view of the present invention, which includes at least one fan 10, a fixing frame 20, and a vacuum aspirator 30. The fixing frame 20 has a plurality of workpiece holders 21 thereon, and the fan 10 may be arranged in any one of the workpiece holders 21. The workpiece holders 21 are each provided with a through-hole 22 in its center, and the fan 10 may form a closed space with the through-hole 22 when placed onto the workpiece holder 21. The fixing frame 20 is provided with a plurality of air flues 23 in communication with corresponding through-holes 22. The vacuum aspirator 30 has a plurality of air pipes 31 connected to the through-holes 22 via the air flues 23. And the through-hole 22 is further provided with a thread (not shown) for the air pipe 31 to be screwed thus forming a state of being closely connected.

[0019]As shown in FIG. 2, it is a schematic view showing that the fan 10 is fixed to the fixing frame 20. The ...

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.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of Invention[0002]The present invention relates to a vacuum adsorbing apparatus for fan positioning, and more particularly to a fixing apparatus for fixing an unmolded fan to a fixing frame with vacuum adsorbing when performing the molding operation of the fan.[0003]2. Related Art[0004]Conventionally, the most important moment during CNC's manufacturing of fan lies in the molding and cutting of the fan, since it is the last stage before having the product finished, and all previous efforts will go wasted if we fail to handle it well. Therefore, some CNC processing plants may utilize ribs to fix the fan during the molding, or may fix the fan to the fixing frame by filling wax or lime and then perform the molding operation of the fan. But the following unavoidable disadvantages will be incurred.[0005](1) The disadvantage of fixing the fan by ribs is the need to trim the fan blade after its molding, however, since the trimming has to be done ma...
