Description

Technical Field

[0001] This utility model provides a hole-opening device, belonging to the field of furniture processing technology, and particularly relates to a hole-opening device for wooden boards used in furniture processing. Background Technology

[0002] Furniture board processing refers to a series of physical and chemical treatments on wood or engineered wood to make it meet the requirements of furniture manufacturing. These processes include, but are not limited to, cutting, drying, splicing, sanding, and coating. Through these processes, raw materials are transformed into boards with specific dimensions, shapes, strengths, and aesthetics, which are ultimately used to assemble and manufacture various furniture products to meet the structural, functional, and decorative needs of furniture.

[0003] Existing processing devices for furniture wood panels typically include a frame, worktable, transmission system, and processing head. The frame supports and secures the entire device. The worktable is where the panels are processed and is usually equipped with suction cups or vacuum devices to hold the panels in place. The transmission system, consisting of servo motors, tracks, and sliders, controls the movement of the processing head, which is the core component for drilling, cutting, and other operations. Different drill bits and cutting tools can be selected and replaced according to specific needs.

[0004] The depth of holes in furniture panel processing plays a crucial role. For example, the locking hole depth of a three-in-one connector is 13.5 mm, the connecting rod hole depth is 33 mm, and the embedded part hole depth is 13 mm; the side plate hole depth of the wooden dowel is 13 mm, and the bottom plate hole depth is 33 mm; the concealed hole depth of the shelf support is 13.5 mm, 7 mm from the edge; the side plate hole depth of a two-in-one connector is 8 mm, the shelf hole depth is 13.5 mm, and the edge distance is 9 mm; the side plate hole depth of the hanging bracket is 13 mm, with 4 rows of holes and a hole spacing of 32 mm. These different hole depths meet the varying connection strength and structural requirements during furniture assembly, while also affecting the furniture's aesthetics and functionality.

[0005] However, while existing structures can limit drilling stability and ensure a smooth drilling process, they often lack the ability to precisely adjust the drilling depth. This is mainly because the device lacks an effective depth adjustment mechanism, or existing adjustment mechanisms are complex to operate, inflexible, and unable to meet the precise adjustments required for different depths. This can lead to insufficient precision in controlling the drilling depth during processing, thus affecting the quality and effect of furniture assembly. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this application provides a wood board drilling device for furniture processing, which solves the problem that the existing devices cannot accurately adjust the drilling depth.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a wood board hole-opening device for furniture processing, including an outer frame, a pair of symmetrically distributed clamping plates fixedly connected to the inner side of the outer frame, a pressure plate movably connected to the inner side of the clamping plates, a limiting plate that penetrates the clamping plates fixedly connected above the pressure plate, and a first scale line provided on the limiting plate; a threaded tube penetrating itself is provided on the middle section of the outer frame, a limiting block fixedly connected above the threaded tube, and a second scale line provided on the limiting block.

[0008] Preferably, the outer frame is inverted U-shaped, including a crossbeam through which a threaded tube passes and a pair of columns fixedly connected to a clamping plate. The crossbeam has a knob that passes through itself and is sleeved on the outside of the threaded tube. A limiting frame sleeved on the outside of the limiting block is integrally connected to the middle section of the side of the crossbeam away from the columns.

[0009] Preferably, the clamping plate is an L-shaped plate body, including a horizontal plate that is penetrated by the limiting plate, and a vertical plate that is perpendicular to both the horizontal plate and the pressure plate. The inner ends of the vertical plate are provided with T-shaped sliding grooves, and the sliding grooves are provided with clamping plates that are integrally connected with the pressure plate.

[0010] Preferably, a spring is connected to the side of the pressure plate near the horizontal plate via a circular groove. One end of the spring is fixedly connected to the pressure plate, and the other end is fixedly connected to the horizontal plate. The spring is located between the limiting plate and the longitudinal plate.

[0011] Preferably, the limiting plate restricts the up-and-down movement of the pressure plate to be stable, the first scale line is used to display the thickness of the furniture wood board below the pressure plate; the limiting block is used to change the distance between the drilling bit and the wood board, the second scale line displays the increased spacing distance, and the length of the drilling bit is equal to the vertical distance from the upper edge of the limiting frame to the lower edge of the clamping plate.

[0012] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0013] This device achieves adjustable drilling depth through the cooperation of a limiting plate and a limiting block, combined with the values ​​of two scale lines. The specific process is as follows:

[0014] When the wooden board is placed under the pressure plate, the pressure plate moves up and down according to the thickness of the board, and the first scale line on the limit plate displays the actual thickness of the board. This value provides the basic data for subsequent calculation of the drilling depth.

[0015] By adjusting the rotation of the threaded tube using the knob, the position of the limit block on the threaded tube can be changed, thereby adjusting the distance between the drill bit and the wooden board. The second scale line on the limit block will show the distance the limit block has moved relative to the outer frame, that is, the distance the drill bit has been lifted, and thus the distance between the drill bit and the ground can be determined.

[0016] The drilling depth is determined by both the thickness of the wooden board (value at the first scale mark) and the distance between the drill bit and the wooden board (value at the second scale mark). The specific calculation formula is as follows:

[0017] Drilling depth = First scale mark value - Second scale mark value

[0018] For example, if the first scale line shows that the thickness of the wooden board is 10 mm and the second scale line shows that the drill bit spacing is 5 mm, then the drilling depth is 5 mm.

[0019] In this way, the device can flexibly adjust the position of the drill bit according to different wood board thicknesses and the required drilling depth, ensuring the accuracy of the drilling.

[0020] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0028] 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.

[0029] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] like Figure 1 and Figure 2 As shown, a wood board drilling device for furniture processing has an overall inverted U-shaped frame structure, consisting of a crossbeam 8 and opposing columns. A pair of clamping plates 2 are symmetrically fixed to the inner side of the outer frame 1. The clamping plates 2 are L-shaped, including a horizontal plate and a vertical plate 11. T-shaped grooves 12 are provided at both ends of the vertical plate 11, and a clamping plate 13 integrated with a pressure plate 3 is embedded in the grooves 12. A limiting plate 4 is fixed above the pressure plate 3, passing through the clamping plates 2 and having a first scale line 5 for displaying the wood board thickness. A threaded tube 6 passing through the crossbeam 8 is provided in the middle section of the outer frame 1. A limiting block 7 is connected above the threaded tube 6, and a limiting frame 10 is fitted on the outside of the limiting block 7. A knob 9 is embedded in the crossbeam 8 for adjusting the position of the limiting block 7. The pressure plate 3 is connected to the horizontal plate by a spring 14 to ensure the stability of the pressure plate 3's vertical movement.

[0032] In this embodiment, the outer frame 1 provides a stable support structure for the entire device, and the clamping plates 2 are symmetrically distributed on the inner side of the outer frame 1 to ensure that the wooden board can be firmly clamped during processing. The inverted U-shaped frame design enhances the overall rigidity of the device, and the symmetrical distribution of the clamping plates 2 ensures that the wooden board is subjected to uniform force during clamping, avoiding board displacement or deformation and improving drilling accuracy.

[0033] The pressure plate 3 moves up and down by being embedded in the sliding groove 12 via the clamping plate 13. The limiting plate 4 passes through the clamping plate 2 and has a first scale line 5 for measuring the thickness of the wood board. The movable design of the pressure plate 3 allows it to automatically adjust its position according to the thickness of the wood board. The first scale line 5 on the limiting plate 4 visually displays the thickness of the wood board, providing basic data for the subsequent calculation of the drilling depth and ensuring the accuracy of the drilling depth.

[0034] A threaded tube 6 passes through a crossbeam 8, and a limiting block 7 is threadedly connected to the threaded tube 6. A knob 9 is embedded in the crossbeam 8 and is used to rotate the threaded tube 6 to adjust the position of the limiting block 7. By adjusting the rotation of the threaded tube 6 using knob 9, the height of the limiting block 7 can be precisely adjusted, thereby changing the distance between the drill bit and the wooden board. This fine-tuning mechanism allows the device to adapt to wooden boards of different thicknesses, enabling flexible adjustment of the drilling depth.

[0035] The limiting frame 10 is fitted over the limiting block 7, and the second scale line 71 on the limiting block 7 displays the movement distance of the limiting block 7 relative to the outer frame 1. The limiting frame 10 restricts the movement range of the limiting block 7, ensuring the stability of the adjustment process. The second scale line 71 visually displays the movement distance of the limiting block 7, facilitating the calculation of the drilling depth and further improving the accuracy of the drilling.

[0036] Spring 14 connects pressure plate 3 to the horizontal plate, ensuring that pressure plate 3 remains stable when moving up and down. The elasticity of spring 14 allows pressure plate 3 to adapt to wooden boards of different thicknesses, while preventing pressure plate 3 from shaking due to external force or vibration, ensuring the stability of the wooden board clamping and preventing the wooden board from shifting when drilling holes.

[0037] Through the synergistic effect of the above structures, this device achieves precise adjustment of drilling depth. The limiting plate 4 and the first scale line 5 provide measurement data for the wood board thickness, while the limiting block 7 and the second scale line 71 are used to adjust the distance between the drill bit and the wood board. Combined with the fine-tuning function of the knob 9, the device can flexibly adjust the drilling depth according to different wood board thicknesses and drilling requirements. This design not only improves drilling accuracy but also enhances the applicability and ease of operation of the device, making it particularly suitable for scenarios in furniture processing where multiple adjustments to the drilling depth are required.

[0038] like Figure 3 and Figure 4 As shown, this device achieves stable clamping of the wooden board through the cooperation of a limiting plate and a pressure plate. The first scale line is used to measure the thickness of the wooden board, ensuring the accuracy of the drilling position. The design of the limiting block and limiting frame allows adjustment of the distance between the drilling drill bit and the wooden board, and the second scale line displays the increased spacing distance, facilitating precise control of the drilling depth. The length of the drilling drill bit is equal to the vertical distance from the upper edge of the limiting frame to the lower edge of the clamping plate, ensuring a stable contact position between the drill bit and the wooden board. This device is suitable for precise drilling of wooden boards in furniture processing, especially suitable for scenarios requiring multiple adjustments to the drilling depth and position.

[0063] Sub-scale: 0.25 mm / division (corresponds to 1 / 4 turn of a threaded pipe)

[0064] III. Measurement System Technical Parameters

[0065] First scale line (5)

[0066] Measurement range: 5-50 mm (wood board thickness)

[0067] Vernier graduation value: 0.5 mm

[0068] Laser etching process was used, with a line width of 0.1 mm.

[0072] Green zone: 0-20 mm (safe processing range)

[0073] Red zone: 20-30 mm (overtravel warning)

[0074] The steps for using this device are as follows:

[0075] First, place the wooden board to be processed under the pressure plate (3) of the device. When the wooden board is in place, the pressure plate (3) will move up and down automatically according to the thickness of the wooden board. The first scale line (5) on the limit plate (4) will display the actual thickness of the wooden board. This value provides the basic data for subsequent calculation of drilling depth.

[0076] Next, by adjusting the rotation of the threaded tube (6) using the knob (9), the position of the limiting block (7) on the threaded tube (6) is changed, thereby adjusting the distance between the drilling bit and the wooden board. The second scale line (6) on the limiting block (7) will show the distance the limiting block (7) moves relative to the outer frame (1), that is, the distance the drill bit is lifted, and thus the distance between the drill bit and the wooden board at this time can be obtained.

[0077] The drilling depth is calculated based on the values ​​of the first scale line (5) and the second scale line (6). The specific calculation formula is: Drilling depth = First scale line value (wood board thickness) - Second scale line value (drill bit spacing). For example, if the first scale line shows a wood board thickness of 10 mm and the second scale line shows a drill bit spacing of 5 mm, then the drilling depth is 5 mm.

[0078] Finally, the drill bit is started to open the hole. The device, through the cooperation of the limiting plate (4) and the limiting block (7), combined with the values ​​of the two scale lines, ensures that the drill bit can flexibly adjust its position according to the thickness of the wooden board and the required drilling depth, thereby achieving precise hole opening.

[0079] In this way, the device can quickly and accurately adjust the drilling depth according to different wood board thicknesses and drilling requirements, thereby improving the efficiency and precision of furniture processing.
