Description

Technical Field

[0001] The invention belongs to the technical field of axial flow fan processing, and in particular relates to an axial flow fan panel punching machine. Background Art

[0002] Axial flow fans generally have cylindrical air cylinders. To facilitate the installation of the air cylinder, it is necessary to drill a mounting hole on the panel at the end of the air cylinder. The existing drilling method is to fix the air cylinder on a rotating mechanism, set a drilling mechanism on one side of the rotating mechanism, and after the drilling mechanism completes drilling of one mounting hole, the rotating mechanism rotates a certain angle to drill the next hole.

[0003] However, in the case of a multi-cylinder axial flow fan, since multiple cylinders are connected in parallel, the above rotary punching method cannot be used for punching. In addition, the cylinder panel rotating mechanism rotates with the cylinder panel, which has a relatively large mass and inertia, and is prone to errors in stopping, resulting in a high deviation rate in the punching position. The above rotary punching method punches one hole at a time, which is inefficient. Summary of the invention
