Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, and in particular to a drilling device for the production of intelligent modular cabinets. Background Technology

[0002] In existing technologies, furniture also involves factors related to materials and appearance. Panels are a crucial component of furniture, and furniture is assembled by combining and installing these panels. Especially for modular cabinets, installation holes need to be drilled in the panels before they are secured using connectors. These holes make installation much easier.

[0003] A search revealed Chinese patent application number 202422046356.0, which discloses a drilling device for furniture production. Through a special design of the first and second clamping plates, two arc-shaped grooves are formed on opposite sides of two square grooves, allowing a circular board to be placed between them. This enables the two square grooves to not only fix the square board but also secure the circular board. Furthermore, the movement of the first clamping plate facilitates the cleaning of sawdust from the top of the processing table, thus enhancing the functionality of the first and second clamping plates and improving the practicality of the drilling device.

[0004] The above-mentioned patent has the following shortcomings: In actual use, the wooden board is fixed on the upper surface of the processing table. When it is necessary to make a hole in the wooden board, the drilling bit is likely to come into contact with the processing table, causing damage to the processing table, or the drilling bit may break, which seriously affects the drilling work of the modular cabinet board. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a drilling device for intelligent modular cabinet production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A punching device for intelligent modular cabinet production, comprising:

[0008] The workbench has a fixed limit frame at its top, and the interior of the limit frame is used for drilling holes in the cabinet panels; a main controller is fixedly installed on one side of the top of the workbench, which is used to control the operation of the entire device.

[0009] The drilling structure is mainly composed of a servo motor fixedly installed inside the connecting mounting cylinder. The bottom end of the output shaft of the servo motor is fixedly installed with a drilling bit through a stabilizing coupling. The bottom end of the connecting mounting cylinder is fixedly connected with a mating protective ring. Multiple sliding connecting rods are equidistantly slidably installed on the top side of the mating protective ring. The bottom end of the multiple sliding connecting rods is fixedly installed with a connecting pressure ring. The bottom end of the connecting pressure ring is fixedly installed with a rubber pad ring. The outer wall of the sliding connecting rod is sleeved with a support spring.

[0010] A drilling mating assembly includes a limiting mounting frame and a drilling mating block. The drilling mating block can freely adjust its horizontal position inside the limiting mounting frame. A sub-controller controlled by a main controller is fixedly installed at one end of the limiting mounting frame. The sub-controller controls the position of the drilling mating block, and the top of the drilling mating block has a mating hole adapted to a drilling drill bit.

[0011] As a further improvement of this utility model: the upper part of both the front and back sides of the limiting mounting frame is provided with a mounting groove, and a mounting slider is slidably installed inside the mounting groove.

[0012] As a further embodiment of this utility model: a threaded rod and a mating slide rod are installed between the two mounting sliders, and both the threaded rod and the mating slide rod penetrate the upper part of the drilled mating block.

[0013] As a further embodiment of this utility model: the threaded rod is threadedly connected to the drilled mating block, and one end of the threaded rod is provided with a driver controlled by a sub-controller.

[0014] As a further improvement of this utility model: the lower part of both sides of the limiting mounting frame is provided with mounting groove 2, and mounting slider 2 is slidably installed inside the mounting groove 2.

[0018] Compared with the prior art, this utility model provides a drilling device for intelligent modular cabinet production, which has the following beneficial effects:

[0019] 1. This intelligent modular cabinet production drilling device establishes a dual-coordinate system by creating a global coordinate system (X,Y) for the limiting frame and a fine-tuning coordinate system (a,b) for the drilling mating component, and achieves precise linkage between the two. This allows for accurate mapping of the global drilling point to the fine-tuning coordinates of the drilling mating block, enabling precise hole positioning. The drilling mating block is located directly below the drilling point on the board, providing precise guidance and support for the drilling bit. This significantly improves drilling verticality and dimensional accuracy, avoids potential impacts from the drilling bit on the worktable, and ensures the continuity and stability of the drilling operation.

[0020] 2. The drilling device used in the production of this intelligent modular cabinet presses down the plate before drilling by connecting a pressure ring, a rubber washer, and a support spring, increasing friction and stability, and further reducing vibration and displacement. The equipment can automatically complete a series of actions such as clamping, positioning the drilling block, positioning the drill bit, pressing down the plate, drilling at a constant speed, lifting the drill bit, and moving to the next hole position.

[0021] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] A drilling device for intelligent modular cabinet production, such as Figures 1 to 4 As shown, it includes: a limiting frame 2 fixedly connected to the top of the workbench 1, a drilling assembly set inside the limiting frame 2, and a drilling structure for drilling holes in the modular cabinet panels.

[0029] Multiple ventilation holes are equidistantly provided on the top of the workbench 1 inside the limiting frame 2 to facilitate the discharge of wood chips generated during drilling and prevent them from entering the limiting frame 2; at the same time, the drilling and fitting components are installed inside the limiting frame 2.

[0030] The limiting frame 2 has multiple support seats 7 for supporting the cabinet panels. Each of the four corners of the bottom of the support seat 7 has a fixed insert. The fixed insert is inserted into the ventilation hole to fix the support seat 7. The top of the support seat 7 is lower than the top of the limiting frame 2, which makes it easy for the cabinet panels to be placed inside the limiting frame 2. When the cabinet panels are placed flat on the support seat 7, the lower part of the side wall of the cabinet panels is in contact with the inner wall of the limiting frame 2, and the upper part of the side wall is above the top surface of the limiting frame 2.

[0031] A main controller 3 is fixedly installed on the top of the workbench 1 on one side of the limiting frame 2. The main controller 3 is used to control the operation of the whole device. On the other side of the limiting frame 2, a mounting frame 4 is fixedly installed on the top of the workbench 1. A clamping cylinder 5 is fixedly installed on the top of the mounting frame 4. A plate clamping head 6 is fixedly installed on the telescopic end of the clamping cylinder 5. The plate clamping head 6 is set on the top of the limiting frame 2 to fix the plate of the combination cabinet.

[0032] Reference Figure 1 The cabinet panel is placed at the top of the support seat 7 inside the limiting frame 2. The panel is manually aligned with the inner wall of the back of the limiting frame 2 and the inner wall of the side closest to the main controller 3. Then, the clamping cylinder 5 is activated by the main controller 3. The clamping cylinder 5 extends and drives the panel clamp 6 to clamp the end of the cabinet panel, thus fixing the cabinet panel inside the limiting frame 2.

[0033] The drilling assembly includes a limiting mounting frame 8 and a drilling mating block 22. The four corners of the bottom end of the limiting mounting frame 8 are integrally formed with fixing posts 2. The fixing posts 2 are inserted into the vent holes to fix the limiting mounting frame 8. The drilling assembly is used in conjunction with multiple support seats 7. The installation position of the limiting mounting frame 8 is determined according to the drilling requirements, and then the support seats 7 are installed. The top surface of the limiting mounting frame 8 and the top surface of the support seat 7 are in the same plane.

[0034] The drilling mating block 22 can freely adjust its horizontal position inside the limiting mounting frame 8. A sub-controller 21 controlled by the main controller 3 is fixedly installed at one end of the limiting mounting frame 8. The sub-controller 21 controls the position of the drilling mating block 22, and the top of the drilling mating block 22 is provided with mating holes for drilling the combination cabinet panels.

[0035] The upper part of both the front and back sides of the limiting mounting frame 8 is provided with mounting grooves 23. Mounting sliders 24 are slidably installed inside the mounting grooves 23. Threaded rods 25 and mating rods 26 are installed between the two mounting sliders 24. Both threaded rods 25 and mating rods 26 pass through the upper part of the drilled mating block 22.

[0036] The threaded rod 25 is threadedly connected to the punched mating block 22 and rotatably connected to the mounting slider 24. One end of the threaded rod 25 is provided with a driver 27 controlled by the sub-controller 21, and the driver 27 is fixedly installed on the corresponding mounting slider 24.

[0037] The lower part of both sides of the limiting mounting frame 8 is provided with mounting groove 28. Mounting slider 29 is slidably installed inside the mounting groove 28. Threaded rod 20 and mating slide rod 21 are installed between the two mounting sliders 29. Threaded rod 20 and mating slide rod 21 both pass through the lower part of the drilled mating block 22.

[0038] The threaded rod 30 is threadedly connected to the punched mating block 22 and rotatably connected to the mounting slider 29. One end of the threaded rod 30 is provided with a driver 32 controlled by the sub-controller 21, and the driver 32 is fixedly installed on the corresponding mounting slider 29.

[0039] Driver 1 27 and Driver 2 32 have the same structure, including a micro servo motor for driving the threaded rod (threaded rod 1 25 and threaded rod 2 30), a battery module for powering the micro servo motor, and a microcontroller for controlling the micro servo motor. The microcontroller is controlled by the sub-controller 21 and sends its own position information to the sub-controller 21. The microcontroller also controls the forward and reverse rotation and start and stop of the micro servo motor.

[0040] Note: The internal structures of the above-mentioned driver 27 and driver 32 are existing mature technologies. This application only describes their functions and control methods, and does not disclose their circuit structure and component structure. Those skilled in the art can fully understand and implement the structure described in this application based on the above content.

[0041] like Figure 1 As shown, at this time, the punched mating block 22 is in the middle of the inner cavity of the limit mounting frame 8. The sub-controller 21 establishes a (a,b) rectangular coordinate system with the position of the axis of the mating hole of the punched mating block 22 as the origin of the coordinate system. The position of the punched mating block 22 in the (a,b) rectangular coordinate system is quickly adjusted by the driver 1 27 and the driver 2 32.

[0042] Note: The construction of the (a,b) rectangular coordinate system mentioned above can be referenced from existing CNC machine tools, which is prior art. Those skilled in the art can fully understand and implement it, so this application will not elaborate further.

[0043] The main controller 3 constructs a (X,Y) rectangular coordinate system with the projection point of the intersection line of the inner wall of the back side of the limiting frame 2 and the inner wall of the side away from the clamping cylinder 5 onto the surface of the worktable 1 as the origin. The construction method can refer to the (a,b) rectangular coordinate system mentioned above. The (a,b) rectangular coordinate system is within the (X,Y) rectangular coordinate system. After the drilling assembly is completed inside the limiting frame 2, the sub-controller 21 automatically sends its own position to the main controller 3, so that the (a,b) rectangular coordinate system and the (X,Y) rectangular coordinate system can be quickly connected.

[0044] Reference Figure 1 Assuming the internal length and width of the limiting frame 2 are 1000mm and 800mm respectively, and the internal length and width of the limiting mounting frame 8 are 200mm and 150mm respectively, then... Figure 1 When the drilling assembly is installed as shown, the origin (0,0) of the (a,b) rectangular coordinate system corresponds to (500,400) in the (X,Y) rectangular coordinate system. In this case, if the opening position of the cabinet panel is at (550,450) in the (X,Y) rectangular coordinate system, it corresponds to (50,50) in the (a,b) rectangular coordinate system. The sub-controller 21 can control the drilling assembly block 22 to quickly move to the (50,50) position in the (a,b) rectangular coordinate system.

[0045] Note: The (a,b) rectangular coordinate system and (X,Y) rectangular coordinate system mentioned above in this application can be easily understood by those skilled in the art and are conventional technical means for those skilled in the art. Therefore, this application will not describe them in more detail.

[0046] The main body of the drilling structure is a servo motor 18 fixedly installed inside the connecting mounting cylinder 13. The bottom end of the output shaft of the servo motor 18 is fixedly installed with a drilling bit 20 through a stabilizing coupling 19. The stabilizing coupling 19 is used to maintain the verticality of the drilling bit 20 and ensure drilling accuracy.

[0047] A protective ring 14 is fixedly connected to the bottom of the connecting mounting cylinder 13. Multiple sliding connecting rods 15 are equidistantly slidably installed on the top side of the protective ring 14. The top of the sliding connecting rod 15 passes through the protective ring 14 and is fitted with a limit ring. A connecting pressure ring 17 is fixedly installed at the bottom of the multiple sliding connecting rods 15. A rubber pad ring is fixedly installed at the bottom of the connecting pressure ring 17. A support spring 16 is sleeved on the outer wall of the sliding connecting rod 15. The friction between the rubber pad ring and the cabinet plate is used to further improve the stability of the cabinet plate during the drilling process.

[0048] Multiple fixed connecting rods 12 are fixedly installed at equal intervals on the outer wall of the connecting mounting cylinder 13. A connecting lifting plate 11 is fixedly installed at the top of the fixed connecting rod 12. A lifting cylinder 10 is fixedly installed at the top of the connecting lifting plate 11. A cylinder bracket 9 is fixedly installed on the outer wall of the lifting cylinder 10.

[0049] A horizontal lateral movement component is installed at the top of the cylinder bracket 9. The horizontal lateral movement component controls the drilling structure to move freely within the horizontal range. Its movement is limited by the (X,Y) rectangular coordinate system constructed by the main controller 3. The structure of the horizontal lateral movement component can refer to the above-mentioned drilling mating component. The drilling mating block 22 is replaced by the cylinder bracket 9, and the other structures are designed according to mechanical requirements and the size of the overall device.

[0050] Alternatively, the horizontal traverse component can be directly referenced from the feed structure of the machine tool post, such as a leadscrew or saddle. There are many existing technologies for implementing horizontal traverse components, and those skilled in the art can easily implement them based on the above functional description. Moreover, this structure is not an innovative structure of this application, and this application will not describe it in more detail.

[0051] Working principle:

[0052] Reference Figures 1 to 4 Assemble the device as shown in the figure;

[0053] When using this device, firstly, the installation positions of the drilling mating component and the support platform are determined according to the size of the cabinet panel and the position of the opening, so that the opening point of the cabinet panel is inside the limiting installation frame 8 and corresponds to the mating hole of the drilling mating block 22; then, the cabinet panel is fixed inside the limiting frame 2; finally, according to the opening point, the main controller 3 sends a command to the sub-controller 21 to quickly move the drilling mating block 22 below the opening point of the cabinet panel, so that the axis of the mating hole coincides with the point, and at the same time, the main controller 3 controls the horizontal traversing component to move. The drilling structure is designed to align the axis of the drill bit 20 with the axis of the mating hole. Then, the lifting cylinder 10 is activated, extending to press the connecting pressure ring 17 against the upper surface of the cabinet panel through the rubber pad. The lifting cylinder 10 descends continuously at a low and uniform speed to drill holes at designated points on the cabinet panel. If there are multiple drilling points within the (a,b) rectangular coordinate system, the main controller 3 controls the sub-controller 21 to quickly adjust the position of the drilling mating block 22 and moves the drilling structure to the corresponding position via the horizontal traverse component to continuously drill holes in the cabinet panel.

[0054] Note: The number of drilling mating components mentioned above can be set to multiple, as long as they do not interfere with each other.

[0055] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
