Description

Technical Field

[0001] This utility model relates to the technical field of door and window processing equipment, specifically to an opening device for door and window processing. Background Technology

[0002] In the door and window manufacturing industry, drilling holes in the profiles is a crucial processing step, designed to provide the foundation for subsequent hardware assembly (such as hinge and lock installation) and profile splicing. As the building decoration industry continues to demand higher performance and aesthetics from doors and windows, the drilling process must not only ensure precise hole placement but also balance processing efficiency and operational safety.

[0003] Traditional hole-drilling devices rely primarily on manual pressure application by operators, resulting in poor drilling stability and requiring considerable effort. Operator hand tremors and uneven pressure can cause hole misalignment. CNC hole-drilling devices, on the other hand, require a higher level of technical skill, increasing worker training. Furthermore, traditional clamping components often employ rigid contact and simple bolt fastening, which is prone to surface damage due to uneven clamping force. Additionally, the vibrations generated by the high-speed rotation of the drill bit during drilling can cause slight displacement of the profile, leading to irregular hole diameters, rough hole walls, and even hole misalignment, resulting in a high scrap rate. Therefore, developing a new type of hole-drilling device for door and window processing with flexible adjustment, stable clamping, and a simple and convenient structure has become an urgent need for industry development.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a hole-opening device for door and window processing, including a hole-opening platform 1, a hole-opening component 2 and a clamping component 3.

[0019] An L-shaped back plate 101 is provided on the opening platform 1, which provides a stable support carrier for the entire opening-related structure, so that it can be firmly fixed on the opening platform 1 and ensure the stability of the overall structure during the opening operation.

[0020] An aperture cutter 102 is provided on the L-shaped back plate 101. The aperture cutter 102 has a cavity, and a guide groove is formed on the outer shell of the aperture cutter 102, connecting to the cavity. The cavity of the aperture cutter 102 is the movement space for the drill bit 208 when performing drilling operations, and it can guide and constrain the movement of the drill bit 208 to a certain extent, preventing the drill bit 208 from deviating during high-speed operation. The guide groove is connected to the cavity, providing path guidance for the movement of subsequent related components, ensuring that the components move according to the preset trajectory.

[0021] The lower end of the outer shell is provided with a rectangular horizontal plate 105, and the rectangular horizontal plate 105 has holes corresponding to the cavity. The outer shell has a first positioning hole 103 for through holes, and a rotating shaft 104 is fitted in the hole, which provides a fulcrum for the installation and rotation of the movable rod 201, so that the movable rod 201 can swing at a certain angle around the rotating shaft 104, thereby adjusting the position and angle of the opening.

[0022] Furthermore, the drilling platform 1 has a rectangular opening 107 to prevent the drill bit 208 from colliding with the drilling platform 1 when drilling downwards, and also to facilitate the discharge of debris generated during drilling from the opening, preventing debris accumulation from affecting the drilling operation.

[0023] Furthermore, support legs 108 are provided at the four corners of the drilling platform 1 to support the entire device stably on the ground, preventing the drilling platform 1 from directly contacting the ground and causing wear, and also preventing the drill bit 208 from directly contacting the ground.

[0024] The opening assembly 2 includes a movable rod 201 and a sliding groove 203. The movable rod 201 has a rectangular groove in the middle, which provides space for the movement of the connecting crossbar 204, allowing the connecting crossbar 204 to slide freely in the rectangular groove, thereby driving the related components to move together.

[0025] The movable rod 201 has a second positioning hole 202 at one end. The rotating shaft 104 slides in conjunction with the second positioning hole 202 and the first positioning hole 103. The second positioning hole 202 slides in conjunction with the rotating shaft 104. In addition, the rotating shaft 104 also engages with the first positioning hole 103. This not only connects the movable rod 201 to the hole opener 102, but also allows the movable rod 201 to rotate and slide around the rotating shaft 104 to a certain extent.

[0026] The slide groove 203 is fixed to the inner walls of both sides of the hole opener 102. The hole opening assembly 2 also includes a connecting crossbar 204 and a strip slider 205. One end of the strip slider 205 has a hole. The strip slider 205 is slidably disposed in the slide groove 203. The connecting crossbar 204 is fitted with the rectangular groove in the middle of the movable rod 201 and the hole on the strip slider 205. The slide groove 203 is fixed to the inner walls of both sides of the hole opening assembly mounting cavity, providing a stable sliding track for the strip slider 205 and ensuring that the strip slider 205 can only move in a straight line along the direction of the slide groove 203.

[0027] A driver connecting block 206 is fixed in the middle of the strip slider 205. A driver 207 is fixed at the lower end of the driver connecting block 206. The driver 207 includes a motor and a power output end. The power output end is fixedly connected to the motor shaft. A drill bit mounting groove is provided at the outer end. A drill bit 208 is installed at the power output end of the driver 207.

[0028] Furthermore, a handle 209 is fixed to one end of the movable rod 201 to facilitate better control of the rotation of the movable rod 201, thereby precisely adjusting the raising and lowering of the drill bit 208 and the drilling depth.

[0029] The clamping assembly 3 includes a pressure plate 301, on which a threaded post 302 is fixedly connected. A threaded hole 106 is opened on a rectangular horizontal plate 105, and the threaded post 302 engages and is fixed with the threaded hole 106. This assembly can tightly press the door and window processing material onto the opening platform 1, preventing the material from moving during the opening process.

[0030] A knob 303 is fixed on the threaded post 302, which increases the contact area between the hand and the threaded post 302, making it easier for workers to rotate the threaded post 302, saving effort and making the operation more convenient.

[0031] A rubber pad 304 is provided at the lower end of the pressure plate 301. On the one hand, it can prevent the pressure plate 301 from directly contacting the surface of the door and window processing parts and causing scratches, thus protecting the appearance quality of the processing parts. On the other hand, it can increase the friction between the pressure plate 301 and the processing parts, improve the stability of clamping, and prevent the processing parts from sliding during the drilling process.

[0032] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
