Description

Technical field:

[0001] The utility model relates to the technical field of profile milling processing, in particular to a double-head process milling machine. Background technology:

[0002] During the production process of doors, windows, curtain walls and sun rooms, it is often necessary to perform milling on profiles, such as processing glue injection holes at both ends of the profile for glue injection and sealing, or processing pin holes at both ends of the profile for installing pins. The prior art generally uses CNC milling machines to mill holes on profiles, such as a profile punching device for doors and windows disclosed in a Chinese patent (authorization announcement number: CN218503385U).

[0003] Although existing CNC milling machines can also realize milling holes in profiles, there are still some shortcomings in practical applications. For example, it is usually necessary to mill holes at both ends of the profile, while existing CNC milling machines can only mill holes at one end of the profile at a time. The profile needs to be re-clamped before the other end of the profile can be milled. This undoubtedly seriously restricts the milling efficiency of the profile. For another example, the two ends of the profile are usually inclined surfaces, so there are sharp corners. During the clamping process of the profile, the sharp corners are easily hit and deformed, which affects the subsequent assembly accuracy. Although the above-mentioned patent also has an anti-collision design for this, the structure is relatively complex and requires two space drives, which increases costs and operation time. Therefore, it is necessary to optimize the design of existing CNC milling machines in order to improve processing efficiency and quality.

[0004] It should be noted that the above contents belong to the technical knowledge of the inventor and do not necessarily constitute prior art. Summary of the invention:
