[0002] In the production process of commercial air conditioners, for the outer cover of the air conditioner, it is first necessary to use profiles to form an outer frame, that is, the profile forms the frame of the outer cover, and then install the cover plate on the outer frame. The cover plate and the frame are fastened and fixed by screws, which requires drilling multiple holes on the profile.

[0003] The current device for drilling multiple holes in profiles requires manual placement of the profile on a drilling table for manual positioning, and after the drilling is completed, manual unloading is required, which is inefficient and labor-intensive, and cannot meet the needs of automated production. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a multi-hole drilling device for profiles that can improve production and processing efficiency, reduce the labor intensity of workers, and improve the overall degree of automation.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:
