Description

Technical Field

[0001] This utility model relates to the field of square tube profile processing technology, specifically to a special CNC drilling and milling machine for square tube profiles. Background Technology

[0002] Square tubular profiles are widely used in door and window frames, curtain wall beams, and sunrooms, with aluminum alloy square tubular profiles being the primary material. To facilitate installation and the mounting of other components on these profiles, drilling and milling are often required. Existing CNC drilling and milling machines are mainly designed for thermally broken aluminum profiles, resulting in relatively complex overall structures, especially the fixtures and rotary drives, which are specifically designed for thermally broken aluminum profiles. For a detailed structural example, refer to the four-axis CNC drilling and milling machine disclosed in Chinese patent (application number: 201310549693.5). However, square tubular profiles typically have simpler structures, and their length is often greater than that of thermally broken aluminum profiles used in doors and windows, leading to inconvenience in use. Therefore, it is necessary to design a dedicated drilling and milling machine for square tubular profiles to improve processing efficiency while minimizing costs.

[0003] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

The frame 1 is equipped with a rotary drive mechanism to drive the tube shaft 12 to rotate. The structure of the tube shaft 12 and platforms 14 achieves support, positioning, and clamping of the square tube profile 22. Multiple drive methods are designed to adjust the rotation of the tube shaft 12, allowing selection based on specific needs in practical applications. The overall machine structure is simple and reasonable, and the installation and adjustment of the square tube profile 22 are convenient and quick.

[0020] The drilling and milling head 11 includes a drilling and milling guide rail 1101 vertically mounted on a sliding plate 10. A drilling and milling slide plate 1102 is slidably mounted on the drilling and milling guide rail 1101. A drilling and milling motor 1103 is mounted on the drilling and milling slide plate 1102. A drilling and milling cutter 1104 is mounted on the drilling and milling motor 1103.

The specific structures of the electric drive mechanism and the pneumatic drive mechanism are given, thereby achieving precise and reliable rotary drive.

[0022] One end of the tube shaft 12 is connected to an electric drive mechanism 18; or, both ends of the tube shaft 12 are respectively connected to an electric drive mechanism 18; or, both ends of the tube shaft 12 are respectively connected to a pneumatic drive mechanism 19. In practical applications, depending on the length of the tube shaft 12, both ends can be driven synchronously or only one end needs to be driven. Electric drive or pneumatic drive can also be selected, and the drive method can be freely combined and selected.

[0023] A support base 20 is provided on the frame 1 at the middle position of the tube shaft 12. Two support rollers 21 are symmetrically arranged on the support base 20. The tube shaft 12 acts on the support rollers 21. No guide rail 13 is designed at the position of the support rollers 21 on the tube shaft 12. When the tube shaft 12 is long, it is prone to bending after long-term use because the middle part is suspended. By adding support rollers 21 in the middle, the bending deformation resistance of the tube shaft can be effectively improved, thereby extending the service life of the equipment and improving the processing accuracy.

[0024] The platform 14 includes two spaced-apart uprights 1401, each with a slider 1402 mounted on a guide rail 13. A carrier plate 1403 is connected to the upper ends of the two uprights 1401, and a backing plate 15 and a clamping cylinder 16 are mounted on the carrier plate 1403. The platform 14 has a simple structural design and facilitates the installation of components such as the clamping cylinder.

[0025] The front end of the frame 1 is vertically equipped with a protective slider 23, on which a protective guide rail 24 slides. A protective bracket 25 is mounted on the protective guide rail 24, and a protective cover 26 is mounted on the protective bracket 25. A protective cylinder 27 is vertically mounted on the frame 1 and is connected to the protective bracket 25. This provides protection, especially during drilling and milling operations, effectively preventing debris from flying onto the worker.

[0026] In practical use, end positioning is usually required. Existing technology can be used to design an end positioning cylinder at one end of the frame, and an end positioning plate can be designed on the end positioning cylinder. This is existing technology and will not be described in detail here. Of course, this application can also achieve end positioning by fastening the platform 14 located at the front end (as the end positioning reference), and then aligning the end of the square tube profile 22 with the end of the platform 14.

[0027] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0028] Any aspects of this utility model not described in detail are known to those skilled in the art.
