[0002] In order to facilitate the installation of fixings such as hinges or hinges, improve the connection strength of the frame, meet the specific design requirements of doors and windows, and facilitate the installation and maintenance of doors and windows, it is necessary to drill holes in the door and window frames through a drilling machine during the processing of doors and windows. For example, the patent document with the authorization publication number CN216828785U in the prior art provides a drilling machine for door and window processing; the device is provided with a rotating rod, which can push the door and window frame, and can drill holes in the door and window frame in conjunction with a cylinder, a motor and a drill bit;

[0003] However, when the device pushes the door and window frames through the transmission rod, the worker needs to limit the frame with his palm. Obviously, this manual positioning method causes vibrations between the drill bit and the frame, making it difficult for the worker to ensure the stability of the frame, which in turn causes the frame to shift, resulting in deviations in the drilling position and a major safety hazard. For this reason, we propose a drilling machine for door and window processing. Utility Model Content

[0026] See also Figure 1-6 The utility model provides a technical solution: a drilling machine for door and window processing, comprising a base 1, with limited seats 2 fixedly installed on both sides of the upper end of the base 1, and driving disks 21 are rotatably installed on the outer ends of the two limited seats 2. Insertion cavities 23 are provided in the middle of the limited seats 2 and the driving disk 21. A concave cavity 22 is provided at the outer end of the limited seat 2, and four mutually fitting positioning blocks 24 are slidably installed at equal intervals in the concave cavity 22. The gaps between the four positioning blocks 24 are matched to form a positioning cavity 25, and a first limited sliding 26 and a second limited sliding 28 are fixedly installed on the inner and outer sides of the positioning block 24, respectively. A first limited sliding groove 27 slidably connected to the first limited sliding 26 is provided in the concave cavity 22, and a second limited sliding groove 29 slidably connected to the second limited sliding 28 is provided inside the driving disk 21.

[0027] Working principle: When installing the door and window frame, the frame is inserted into the two limit seats 2 through the insertion cavity 23, and the driving disk 21 is rotated at the outer ends of the two limit seats 2. The sliding connection between the first limit slide 26 and the first limit slide groove 27 in the concave cavity 22 restricts the movement direction of each positioning block 24, so that the rotating driving disk 21 can drive each positioning block 24 to retract inward through the sliding connection between the second limit slide groove 29 and the second limit slide 28, so that each positioning block 24 fits against the periphery of the frame, thereby achieving the effect of positioning the frame.

[0028] As a further description of the above technical solution: a first motor 11 is fixedly installed on the upper end of the base 1, and driving gears 12 are fixedly installed on both ends of the first motor 11 through its output shaft, and the driving gears 12 on both sides correspond to the driving disks 21 on both sides, and the corresponding driving gears 12 and driving disks 21 are meshed and connected with each other.

[0029] Specifically, a first motor 11 is set and started, and the driving gear 12 can be driven to rotate through its outer output shaft, and then the two driving disks 21 can be driven to rotate at the same time through the meshing effect between the driving gear 12 and the driving disk 21, thereby improving the operational efficiency.

[0030] As a further description of the above technical solution: a movable ring 3 is rotatably installed between the two limit seats 2, a cylinder 32 and a handle 31 are fixedly installed on the periphery of the movable ring 3, a movable frame 33 is provided in the movable ring 3, and the front end of the cylinder 32 is fixedly connected to the rear end of the movable frame 33 through its output shaft; a second motor 34 is fixedly installed in the movable frame 33, and a drill bit 35 is fixedly installed on the front end of the second motor 34 through its output shaft, and the drill bit 35 is arranged on the front side of the movable frame 33.

[0031] Specifically, after the frame is installed, when it is necessary to drill a hole in the frame, the movable ring 3 can be rotated between the two limit seats 2 through the handle 31 to adjust the drilling position, and the cylinder 32 can be started to adjust the position of the movable frame 33 so that the drill bit 35 contacts the periphery of the frame, and then the second motor 34 is started to drive the drill bit 35 to rotate, thereby achieving the effect of drilling a hole in the door and window frame.

[0032] As a further description of the above technical solution: a dust guiding chamber 4 is opened in the base 1, and dust guiding holes 41 which are interconnected with the upper end of the dust guiding chamber 4 are opened at the lower ends of the two limit seats 2 respectively, and a dust guiding pipe 42 which is interconnected with the rear end of the dust guiding chamber 4 is fixedly installed at the outer end of the base 1; an installation cavity 43 is opened on the upper side of the outer periphery of the dust guiding pipe 42, and a filter screen 45 is inserted and installed in the installation cavity 43, and a fan 44 is fixedly installed in the dust guiding pipe 42 through a bracket, and the fan 44 is arranged on the rear side of the filter screen 45.

[0033] Specifically, when drilling a hole in the frame through the drill bit 35, the fan 44 is started to guide the air in the inner cavity of the limit seat 2 and the movable ring 3, and the outside air is guided into the movable ring 3 through the gap between the drive disk 21 and the limit seat 2 and the positioning block 24. Then, the air in the inner cavity of the movable ring 3 can be led out to me through the dust guide hole 41, the dust guide cavity 4 and the dust guide tube 42. When the air passes through the filter 45, the filter 45 can block the door and window frame debris in the air. The filter 45 can be installed and disassembled through the installation cavity 43, so as to facilitate the collection of frame debris.
