Description

Technical Field

[0001] This utility model relates to the technical field of door and window processing equipment, and in particular to a device for opening drainage holes in doors and windows. Background Technology

[0002] In the manufacturing process of doors and windows, drainage holes need to be opened at specific locations in the door and window profiles to drain rainwater that may seep into the profile cavity. Existing technology announcement CN219924626U discloses a door and window drilling device, which includes a workbench and a drilling assembly. A stop block is rotatably connected to the front side wall of the workbench. A collection box is fixedly connected to the bottom of the workbench. Guide rails are fixedly connected to both sides of the workbench. A slide rail is fixedly connected to the bottom of the guide rail. A circular handle is slidably connected inside the guide rail. A brush rod is fixedly connected to the circumference of the circular handle. A strip brush is engaged at the bottom of the brush rod. Screws are threaded to the top of both ends of the brush rod. A half-moon clamp is threaded to the bottom of the screw. A lead screw is threaded to the middle of the half-moon clamp. A pressure block is fixedly connected to the end of the lead screw near the guide rail. A knob is fixedly connected to the end of the lead screw away from the guide rail. A rotating shaft is rotatably connected to the bottom of the half-moon clamp. A slider is fixedly connected to the top of the rotating shaft. The slider and the slide rail are slidably connected.

[0003] However, to ensure the drainage system matches the building's wall structure and to avoid damaging the original waterproofing layer by cutting grooves in the wall, the drainage holes are usually created on-site by the construction team after installation. Current technology cannot perform this creation operation. Currently, the common method is for workers to use a hand drill with a simple template or by directly marking lines to drill the holes. This method has several drawbacks: First, the accuracy of the hole positions is difficult to guarantee, and errors in marking or template positioning can easily lead to uneven drainage hole positions; second, the drill bit is prone to deviation during drilling, resulting in incorrect drainage channel direction, affecting drainage efficiency and aesthetics; third, hand-held operation poses safety hazards and is inefficient. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a door and window drainage hole opening device that can quickly and accurately open drainage holes on door and window profiles, effectively avoiding problems such as hole position deviation and inconsistent drainage groove direction caused by traditional marking and drilling, and significantly improving processing efficiency, accuracy and operational safety.

[0005] This utility model discloses a device for opening drainage holes in doors and windows, comprising a base, a positioning mechanism, a guiding mechanism, and a drilling unit. The positioning mechanism is used to quickly and accurately position and clamp the device onto the door and window profile; the guiding mechanism is used to precisely guide the drill bit, ensuring the verticality and positional accuracy of the drilling; and the drilling unit is used to provide drilling power.

[0006] Preferably, the positioning mechanism includes a slidably adjustable backrest and a first locking element. By sliding and locking the backrest, it can adapt to profiles of different widths or different hole requirements, achieving precise horizontal positioning.

[0007] Preferably, the positioning mechanism further includes a clamping assembly, which comprises a clamping block and a clamping drive component. The clamping drive component drives the clamping block to work in conjunction with the backing wall to firmly clamp the door / window profile in the middle, preventing the profile from moving or the device from shifting during drilling.

[0008] Preferably, the clamping drive component includes a fixed frame, a threaded rod, a knob, a connecting plate, and a slide rod. The bottom of the fixed frame is installed at the bottom of the base. The threaded rod is screwed onto the lower part of the fixed frame. A knob is installed at the front end of the threaded rod. A clamping block is rotatably installed at the rear end of the threaded rod. Slide rods are installed on the left and right sides of the clamping block. The slide rods are slidably installed on the left and right sides of the lower part of the fixed frame. A connecting plate is installed at the front end of the slide rod. The middle part of the connecting plate is rotatably connected to the threaded rod. Rotating the knob causes the threaded rod to push the clamping block to move, which, in conjunction with the backing, firmly fixes the device to the profile. When the clamping block moves, it drives the slide rod to slide on the fixed frame, limiting and guiding it, improving structural strength, and ensuring the stability of the fixation.

[0009] Preferably, the guiding mechanism includes a guide seat and a guide sleeve replaceably mounted thereon. By replacing the guide sleeve with one of different inner diameters, drill bits of different diameters can be accommodated to create drainage holes of different sizes.

[0010] Preferably, the drilling unit is connected to the base via a feeding mechanism. The feeding mechanism can be a manual feeding mechanism, including a guide rail slider assembly, a movable plate, and a handle, allowing the operator to control the drill bit's feed and retraction by pushing or pulling the handle; alternatively, it can be an automatic feeding mechanism, driven by a pneumatic or electric cylinder, to achieve automated operation and further improve efficiency and consistency.

[0011] Preferably, it also includes a chip collection hood, which is installed on the lower part of the guide seat via an insert block and is located below the guide sleeve. It is used to collect aluminum or plastic chips generated during drilling, keep the working environment clean, and reduce safety hazards.

[0012] Compared with existing technologies, the advantages of this utility model are as follows: 1. High precision: The adjustable backrest and precision guide sleeve ensure that the position and verticality of each drainage hole are highly consistent. 2. High efficiency: The rapid positioning and clamping mechanism, combined with a stable feed method, significantly improves the single-hole processing efficiency, making it especially suitable for batch production. 3. Good safety: The handheld electric drill is replaced with a fixed drilling machine, and a chip collection cover is installed, effectively avoiding the risk of drill bit injury and flying chips. 4. Strong versatility: By adjusting the backrest position and changing the guide sleeve, it can adapt to various specifications of door and window profiles and drainage hole size requirements. 5. Simple operation: Workers do not need high-level skills to complete precise operations, reducing the technical requirements for operators. Attached Figure Description

During operation, the sliding support 2 is first roughly positioned according to the designed location of the drainage hole on the door and window profile. Then, the device is secured to the profile, with the support 2 tightly against one edge of the profile. Finally, the first locking member 3 is locked. Then, the knob 18 is rotated to move the threaded rod 17, pushing the clamping block 4 to move. This, in conjunction with the support 2, firmly fixes the device to the profile. As the clamping block 4 moves, it drives the sliding rod 20 to slide on the fixing frame 16, limiting and guiding it, improving structural strength, and ensuring the stability of the fixation, thus firmly fixing the device to the profile. The motor 8 is started, and the drill bit 9 begins to rotate. The operator smoothly pushes the handle 12 forward, driving the movable plate 11 and the drilling unit to move forward along the guide rail. The drill bit 9, precisely guided by the guide sleeve 7, drills a precise drainage hole in the profile. The drilling debris is collected by the debris collection cover 13. After drilling is completed, pull back handle 12 to remove the drill bit, release clamping block 4, and the device can be moved to the next station.
