[0002] In the field of machining, drilling profiles (such as metal and plastic profiles) is a common processing procedure, widely used in industries such as construction, automotive, and furniture manufacturing. Traditional profile drilling devices typically employ fixed positioning structures or manual adjustment mechanisms, drilling holes in the profile surface using a drill bit. Traditional devices rely heavily on manual adjustment of the profile position or single-dimensional mechanical positioning, making it difficult to achieve rapid and accurate alignment of multiple holes. Especially when processing irregular or curved profiles, rigid clamping structures can easily lead to profile misalignment or drilling misalignment, affecting the finished product yield. Furthermore, traditional devices rely heavily on manual adjustment of the profile position or single-dimensional mechanical positioning, making it difficult to achieve rapid and accurate alignment of multiple holes.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0020] Example

[0021] This utility model provides a profile drilling device, such as Figures 1-3 As shown, the system includes a frame 1, which is a steel frame structure. A mounting frame 2 is installed on the top of the frame 1. The mounting frame 2 is a portal frame structure, providing good stability when installed on top of the frame 1. The mounting frame 2 has an inlet / outlet channel in the middle for the plate 15 to pass through, and several transfer rollers 7 are installed along the extension direction of the frame 1 to reduce friction between the plate 15 and the frame 1, preventing wear. A mounting platform 4 is installed on the side wall of the mounting frame 2 along its width. A first drive structure 3 is installed on the mounting frame 2 to drive the mounting platform 4 laterally. A second drive structure 5 is installed on the side wall of the mounting platform 4, and a retainer 6 is installed at the output end of the second drive structure 5. The first drive structure 3 controls the lateral movement of the mounting platform 4, and the second drive structure 5 controls the vertical movement of the retainer 6 and the drilling mechanism. This dual-drive coordination enables multi-dimensional precise positioning of the drilling position, improving the processing range. A drilling mechanism is installed on the side wall of the retainer 6. The drilling mechanism includes a drive motor 10 mounted on the retainer 6. The drive motor 10 is a high-power drive motor 10. A drill bit 11 is rotatably mounted on the retainer 6. The drill bit 11 is connected to the output end of the drive motor 10. The drill bit 11 is detachably connected to the output end of the drive motor 10 by being clamped by a drill bit clamp.

[0022] In some technical solutions of this utility model, the first drive structure 3 and the second drive structure 5 have the same structure, and the first drive structure 3 is an electric push rod structure. The adoption of a general-purpose electric push rod structure, a conventional technical means, ensures that this structure is easy to maintain and saves costs.

[0023] In some technical solutions of this utility model, guide sleeves 16 are installed on the upper side wall of the mounting platform 4. There are two sets of guide sleeves 16, located on opposite sides of the second drive structure 5. A guide rod 17, connected to the retainer 6, is installed inside the guide sleeve 16. The guide rod 17 is a light axis and is slidably disposed within the guide sleeve 16. The cooperation between the guide sleeves 16 on the mounting platform 4 and the guide rods 17 on the retainer 6 effectively reduces shaking during drilling, ensures the linear motion trajectory of the drill bit 11, and improves drilling accuracy.

[0024] In some technical solutions of this utility model, a positioning mechanism for positioning the drilled hole is installed on the retainer 6. The positioning mechanism includes two positioning platforms 12 arranged in pairs. Slide grooves, which are wedge-shaped, are formed vertically on the two opposing side walls of the retainer 6. The two positioning platforms 12 are slidably disposed within the two slide grooves. A positioning plate 13 is installed on the side wall of the positioning platform 12 opposite to the frame 1. A limiting spring 14 connected to the positioning platform 12 is installed in the slide groove. The design of the slide groove and limiting spring 14 of the positioning platform 12 allows the positioning plate 13 to adaptively adjust its height according to the surface shape of the profile and apply constant pressure, preventing the profile from shifting due to uneven clamping force.

[0025] In some technical solutions of this utility model, the positioning plate 13 is installed obliquely on the side wall opposite to the positioning platform 12 and the frame 1, and the included angle of the reverse extension lines of the two positioning plates 13 is an acute angle. The reverse extension lines of the two positioning plates 13 form an acute angle (such as a "V" shape), forming a self-centering clamping effect, which is suitable for profiles of different thicknesses or corrugations, and improves versatility.

[0026] In some technical solutions of this utility model, a rotating shaft is rotatably provided on the side wall of the mounting platform 4, the positioning plate 13 is connected to the rotating shaft, and a torsion spring is sleeved on the rotating shaft. One end of the torsion spring is connected to the positioning plate 13, and the other end of the torsion spring is connected to the mounting platform 4. The positioning plate 13 is connected to the rotating shaft and the torsion spring, and the contact surface can be dynamically adjusted according to the angle of the profile surface, further adapting to the processing requirements of irregular profiles.

[0027] In some technical solutions of this utility model, the frame 1 is provided with an adjustment mechanism that drives the mounting frame 2 to move along its extension direction. A guide strip 9 is installed on the side wall of the frame 1, and guide holes adapted to the guide strip 9 are opened on the side wall of the mounting frame 2. The mounting frame 2 as a whole can move along the extension direction of the frame 1, expanding the processing range and supporting multi-position continuous drilling of long profiles. Furthermore, an adjusting motor 8 is installed on the mounting frame 2, and a rack is installed on the side wall of the frame 1. A gear meshing with the rack is installed on the output end of the adjusting motor 8. Thus, when the mounting frame 2 as a whole moves along the extension direction of the frame 1, it can achieve self-locking, improving the drilling accuracy of this structure at different positions on the sheet metal 15.

[0028] The working process of this device is as follows:

[0029] The mounting bracket 2 is driven by the adjustment mechanism to move along the extension direction of the frame 1, so that the drilling mechanism is roughly aligned with the area to be processed on the profile. The profile is placed on the frame 1. When the retainer 6 moves downward, the two positioning plates 13 contact the profile surface under the action of the limit spring 14, dynamically centering and clamping the profile. If the profile surface is uneven, the positioning plates 13 can slide along the groove and adjust the angle by rotating with the torsion spring to ensure a proper fit. The first drive structure 3 (electric push rod) pushes the mounting table 4 to move laterally, and combined with the constraints of the guide sleeve 16 and the guide rod 17, precisely adjusts the horizontal position of the drill hole. The second drive structure 5 drives the retainer 6 to move vertically downward, and the drive motor 10 drives the drill bit 11 to rotate, completing the drilling. The guide rod 17 ensures no deviation during the downward pressing process, and the limit spring 14 provides buffering to prevent drill bit overload. After drilling is completed, the second drive structure 5 resets and lifts the drill bit 11. The first drive structure 3 can move laterally to the next hole position as needed, or the adjustment mechanism can adjust the mounting bracket 2 for long-distance movement to achieve continuous processing.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
