Description

Technical Field

[0001] The present application relates to the field of fan production and processing, and in particular to a fan impeller assembly tool. Background Art

[0002] The fan includes a motor and an impeller. Figure 1 As shown, it includes a base plate 1, an air guide plate 13 and a plurality of blades 12. The base plate 1 is a circular flat plate with a central axis hole 111 coaxially opened in the middle. The air guide plate 13 is venturi-shaped. A plurality of blades 12 are arranged in a circular array between the base plate 1 and the air guide plate 13. One end of the blade 12 is welded to the base plate 1, and the other end is welded to the air guide plate 13. Positioning protrusions 121 for positioning are integrally formed at both ends of the blade 12. Positioning holes 11 for inserting the protrusions of the blade 12 are opened on the base plate 1 and the air guide plate 13. After the positioning protrusions 121 are inserted into the positioning holes 11, the relative positions of the blade 12 and the base plate 1 or the air guide plate 13 are determined, and the welding operation can be performed.

[0003] The current welding method is to place the base plate on the workbench, splice the blade plate and the air guide plate upward in sequence, and then hold the air guide plate for welding. This operation has poor placement stability of the workpiece during the welding process, which ultimately results in low welding accuracy of the finished product. Utility Model Content

[0013] By adopting the above technical solution, the pressure plate applies thrust to the air guide plate when it abuts against it. At this time, the pressure plate and the workbench form a clamping and fixing state for the base plate, the blade plate and the air guide plate. The matching groove enables the pressure plate to have a stable structural match with the Venturi-shaped air guide plate.

[0014] Preferably, the basic mechanism also includes a fixed axis rod, one end of which is fixedly connected to the workbench, and the fixed axis rod is coaxial with the base plate and the air guide plate.

[0016] By adopting the above technical solution, when the auxiliary hole is inserted by the fixed axis rod, the auxiliary plate is prevented from rotating by the anti-rotation convex strip and the anti-rotation groove, that is, the pressure plate and the auxiliary plate are also relatively fixed laterally relative to the workbench.

[0017] Preferably, a connecting bolt is threadedly connected to the pressure plate, and the connecting bolt passes through the auxiliary plate, and the screw head of the connecting bolt is located on the side of the auxiliary plate away from the pressure plate.

[0018] By adopting the above technical solution, the connecting bolts allow the pressure plate and the auxiliary plate to have a certain movable space while being connected.
