Description

Technical Field

[0001] This invention relates to the field of wire hole opening device technology, specifically a wire hole opening device for the production and processing of indoor office desks. Background Technology

[0002] Drilling cable holes for indoor office desks is a crucial step in furniture production. It's essential to ensure precise hole diameters, smooth, burr-free hole walls, and prevent wood cracking and sawdust from flying everywhere. This is crucial for accommodating the wiring needs of electrical wires, data cables, and other cables, ensuring both the safety and aesthetics of the desk. Traditional cable hole drilling devices have significant limitations: unstable clamping and positioning of the desk board, easily causing hole displacement due to vibration; sawdust flying during drilling pollutes the environment and can remain inside the holes, requiring secondary processing; lack of integrated splash protection and dust collection design affects operator health; and insufficient flexibility of the drilling mechanism makes it difficult to adapt to the multi-position cable hole drilling needs of desks of different sizes. With the furniture industry's increasing demands for production efficiency, processing precision, and environmental protection, the requirements for the positioning accuracy, splash protection and dust collection capabilities, and flexible adaptability of cable hole drilling devices have significantly increased.

[0003] Chinese patent CN119610300A discloses a drilling device for solid wood furniture board production, which can conveniently clean up wood chips and has the advantages of low noise and low energy consumption. However, it cannot reduce the vibration of the wood board during drilling, resulting in unstable board clamping and positioning, vibration causing wire hole displacement, wood cracking, and wood chip splashing that pollutes the environment. Summary of the Invention

[0004] To solve the above problems, the present invention is implemented through the following technical solution: a wire hole opening device for indoor office desk production and processing, including a support base, a first connecting bracket fixedly connected to the top of the support base, two sets of the first connecting brackets being symmetrically distributed on the top of the support base, a first connecting groove being opened on one side of the first connecting bracket, a first electric guide rail being fixedly connected to one side of the inner wall of the first connecting groove, a clamping and positioning device being fixedly connected to the side of the slider inside the first electric guide rail, a support top plate being fixedly connected to the top of the support base located on one side of the first connecting bracket via a bracket, a cross guide rail being fixedly connected to the bottom of the support top plate, a fixed end of a telescopic cylinder being fixedly connected to the bottom of the slider inside the cross guide rail via a bracket, a third connecting bracket being fixedly connected to the movable end of the telescopic cylinder, an anti-splash device being sleeved and fixedly connected to the side of the third connecting bracket, a drill bit mechanism being fixedly connected to the bottom of the third connecting bracket, a dust collection mechanism being connected to the top side of the anti-splash device via a pipe, and a chip collection box being fixedly connected to the bottom of the support base.

[0005] Preferably, the bottom of the dust collection mechanism is fixedly connected to the top of the support plate. Two sets of clamping and positioning devices are provided, each fixedly connected to the side of the slider inside the first electric guide rail. The office desk board to be processed is placed on the top of the support base. According to the size of the board, the first electric guide rails on the two sets of first connecting brackets are activated, and the distance between the clamping and positioning devices on both sides is adjusted to clamp and position the board from both sides. The horizontal position of the drill bit mechanism is adjusted through the cross guide rail to align it with the preset line hole opening point. The telescopic cylinder is activated to drive the third connecting bracket to move the drill bit mechanism and the anti-splash device down synchronously until the anti-splash device fits against the surface of the board to form a working space. The drill bit mechanism is activated to drill the line hole in the board. At the same time, the dust collection mechanism is activated to quickly suck up and process the sawdust and dust generated during drilling through the connecting pipe at the top of the anti-splash device to prevent dust from spreading. Some larger sawdust falls directly into the sawdust storage box at the bottom of the support base for centralized collection.

[0006] Preferably, the clamping and positioning device includes a positioning base. The top and one side of the positioning base are respectively provided with a first moving groove and a second moving groove. The bottom of the positioning base is fixedly connected to the fixed end of a first electric telescopic rod via a bracket. The movable end of the first electric telescopic rod is fixedly connected to a width and height clamping device. The side of the width and height clamping device is slidably connected to the inner wall of the first moving groove. The top of the positioning base located on one side of the first moving groove is fixedly connected to a fourth connecting bracket. A first spring is fixedly connected to one side of the fourth connecting bracket. A first elastic top plate is fixedly connected to one side of the fourth connecting bracket via the first spring. A guide rail is fixedly connected to the side of the first elastic top plate located on the side of the first spring. The side of the first elastic top plate is slidably connected to the fourth connecting bracket via the guide rail.

[0007] Preferably, there are two sets of the first and second moving slots symmetrically distributed on the positioning base, two sets of the first electric telescopic rods symmetrically distributed at the bottom of the positioning base, and the inner wall of the second moving slot is fixedly connected to the side of the slider inside the first electric guide rail.

[0008] Preferably, the first springs are provided in multiple sets and evenly distributed on one side of the fourth connecting bracket, and the guide rails are provided in two sets and symmetrically distributed on the side of the first elastic top plate. When the two sets of first electric telescopic rods at the bottom of the positioning base are activated, their movable ends drive the width and height clamping device to slide left and right along the first moving groove, approaching and fitting the side of the plate from the width direction. Under the pre-tightening force of the multiple sets of evenly distributed first springs, the first elastic top plate on one side of the fourth connecting bracket at the top of the positioning base is tightly fitted to the side of the plate from the length direction. The elastic deformation of the springs absorbs the clamping stress, avoiding rigid contact that could cause damage to the surface of the plate. The two sets of guide rails on the side of the first elastic top plate ensure that the top plate slides smoothly along the fourth connecting bracket under the action of the first spring.

[0009] Preferably, the width and height clamping device includes a fifth connecting bracket. A fixed end of a first elastic telescopic rod is fixedly connected to one side of the fifth connecting bracket. Multiple sets of the first elastic telescopic rods are evenly distributed on one side of the fifth connecting bracket. A second elastic top plate is fixedly connected to the side of the fifth connecting bracket via the first elastic telescopic rods. A fixed end of a second electric telescopic rod is fixedly connected to the top of the fifth connecting bracket. A sixth connecting bracket is fixedly connected to the movable end of the second electric telescopic rod. A second elastic telescopic rod is fixedly connected to the bottom of the sixth connecting bracket. Two sets of the second elastic telescopic rods are symmetrically distributed at the bottom of the sixth connecting bracket. A third elastic top plate is fixedly connected to the bottom of the sixth connecting bracket via the second elastic telescopic rods.

[0010] Preferably, the bottom of one side of the fifth connecting bracket is fixedly connected to the movable end of the first electric telescopic rod, and one side of the fifth connecting bracket is slidably connected to the inner wall of the first moving groove. When the first electric telescopic rod at the bottom of the positioning base is activated, the fifth connecting bracket of the width and height clamping device is driven to slide left and right along the first moving groove until the second elastic top plate approaches the side of the plate. At this time, the multiple sets of first elastic telescopic rods on one side of the fifth connecting bracket generate elastic thrust, pushing the second elastic top plate to fit tightly against the side of the plate. When the second electric telescopic rod is activated, its movable end pushes the sixth connecting bracket to move vertically downward, causing the third elastic top plate to approach the top of the plate. When the third elastic top plate contacts the plate, the two sets of second elastic telescopic rods at the bottom of the sixth connecting bracket begin to compress, forming a flexible clamping force using elastic reaction force.

[0011] Preferably, the splash-proof device includes a first connecting housing, a connecting ring fixedly connected to the inner wall of the first connecting housing, a first vent on the connecting ring, a second connecting housing and a third connecting housing fixedly connected to the bottom of the first connecting housing respectively, a second spring fixedly connected to the bottom of the first connecting housing located between the second and third connecting housings, a splash-proof housing fixedly connected to the bottom of the first connecting housing via the second spring, a second vent on the side of the splash-proof housing, multiple sets of the second vent evenly distributed on the side of the splash-proof housing, and an elastic washer fixedly connected to the bottom of the splash-proof housing.

[0012] Preferably, multiple sets of the first vents are evenly distributed on the connecting ring, and multiple sets of the second springs are evenly distributed at the bottom of the first connecting housing. When the telescopic cylinder is activated to drive the device downward, the elastic washer at the bottom of the splash-proof housing first adheres to the surface of the board. The multiple sets of second springs at the bottom of the first connecting housing are simultaneously compressed, and the elastic reaction force makes the elastic washer tightly fit the surface of the board, adapting to boards of different thicknesses. In conjunction with the second and third connecting housings, the dust and fine wood chips generated during drilling are drawn into the interior of the splash-proof housing through the second vents under negative pressure. The gas is then quickly sucked in through the multiple sets of first vents on the connecting ring, and then efficiently sucked in by the dust collection mechanism through the top connecting pipe. Larger wood chips fall directly into the chip collection box for centralized collection.

[0013] This invention provides a wire hole drilling device for the production and processing of indoor office desks. It has the following beneficial effects: 1. This indoor office desk manufacturing and processing wire hole drilling device places the office desk board on a support base. The distance between the clamping and positioning devices on both sides is adjusted by the first electric guide rail to firmly clamp the board from both sides, ensuring that it does not shift during drilling and guaranteeing drilling accuracy. After the drill bit mechanism is aligned with the drilling point via the cross guide rail, the telescopic cylinder is activated, which moves the drill bit and anti-splash device downward. The anti-splash device fits against the board to form a closed space to prevent sawdust from flying and injuring people or polluting the environment. At the same time as the drill bit starts drilling, the dust collection mechanism is activated, and dust and fine chips are quickly sucked away. Larger sawdust falls into the bottom chip collection box for centralized collection. This solves the problems of board shifting and dust pollution caused by traditional drilling, which not only improves the accuracy and efficiency of wire hole processing, but also optimizes the working environment, reduces cleaning difficulty, and enhances operational safety and practicality.

[0014] 2. The wire hole opening device for the production and processing of this indoor office desk activates two sets of first electric telescopic rods at the bottom of the positioning base, driving the width and height clamping device to slide left and right along the first moving groove. It completes the initial positioning by adhering to the side of the board in the width direction. At the same time, the first elastic top plate at the top of the positioning base, under the pre-tightening force of multiple sets of first springs, tightly adheres to the board in the length direction. The elastic deformation of the springs can absorb the clamping stress and avoid surface damage. Two sets of guide slides ensure the smooth sliding of the top plate, ensuring tight clamping and adapting to thickness differences through the adaptive deformation of the springs. The sliding stroke of the width and height clamping device can match boards of different widths, solving the problems of poor adaptability and easy damage to workpieces caused by traditional devices.

[0015] 3. The hole-opening device for the production and processing of indoor office desks activates the first electric telescopic rod, driving the fifth connecting bracket of the width and height clamping device to slide left and right along the first moving groove. Multiple sets of first elastic telescopic rods push the second elastic top plate to fit against the side of the board, achieving stable clamping in the width direction. The elastic structure can adapt to slight concavity and convexity on the side of the board, avoiding surface damage and absorbing drilling vibration to prevent displacement. For thickness differences, the second electric telescopic rod is activated to drive the third elastic top plate to move down. The second elastic telescopic rod is compressed to form a flexible clamp, ensuring that thin materials do not slip and thick materials are not damaged, adapting to different thickness requirements. In addition, the first elastic top plate fits against the board in the length direction under the action of the first spring, solving the problems of poor adaptability and insufficient protection of traditional devices. It is compatible with various specifications of boards, improves the accuracy and efficiency of hole opening, is convenient to operate and maintain, and optimizes the production process.

[0016] 4. The wire hole drilling device for this indoor office desk manufacturing process involves activating a telescopic cylinder to drive the device downwards. The elastic washer at the bottom of the splash-proof shell first adheres to the surface of the board. Multiple sets of second springs at the bottom of the first connecting shell are simultaneously compressed, using elastic reaction force to ensure the elastic washer tightly fits the board surface. In conjunction with the second and third connecting shells, dust and fine wood chips generated during drilling are drawn into the splash-proof shell under negative pressure. The gas first enters through the second vent, then is quickly sucked in through multiple sets of first vents on the connecting ring, and then efficiently sucked in by the dust collection mechanism through the top connecting pipe. Larger wood chips fall directly into the chip collection box for centralized collection. This device is suitable for boards of different thicknesses, solving the problems of wood chip splashing and dust diffusion during traditional drilling, ensuring a clean working environment, improving waste chip disposal efficiency, and avoiding damage to the board surface caused by rigid contact. This optimizes the safety and practicality of wire hole drilling. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The top part located on one side of the first connecting bracket 2 is fixedly connected to a supporting top plate 6 via a bracket. The bottom of the supporting top plate 6 is fixedly connected to a cross guide rail 7. The bottom of the slider inside the cross guide rail 7 is fixedly connected to the fixed end of a telescopic cylinder 8 via a bracket. The movable end of the telescopic cylinder 8 is fixedly connected to a third connecting bracket 10. A splash guard 9 is sleeved and fixedly connected to the side of the third connecting bracket 10. A drill bit mechanism 11 is fixedly connected to the bottom of the third connecting bracket 10. A dust collection mechanism 12 is connected to the top side of the splash guard 9 via a pipe. A chip storage box 13 is fixedly connected to the bottom of the supporting base 1.

[0021] The bottom of the vacuuming mechanism 12 is fixedly connected to the top of the support plate 6, and two sets of clamping and positioning devices 5 are provided, both of which are fixedly connected to the side of the slider inside the first electric guide rail 4.

[0022] In use, place the office desk board to be processed on top of the support base 1. Activate the first electric guide rails 4 on the two sets of first connecting brackets 2 according to the board size, and adjust the spacing of the clamping and positioning devices 5 on both sides to clamp and position the board from both sides, ensuring that the board does not shift or shake during the drilling process and guaranteeing drilling accuracy. Adjust the horizontal position of the drill bit mechanism 11 using the cross guide rail 7 to align it with the preset drilling point. Activate the telescopic cylinder 8 to drive the third connecting bracket 10, causing the drill bit mechanism 11 and the anti-splash device 9 to move downwards synchronously until the anti-splash device 9 fits against the board surface to form a working space, preventing sawdust from flying during drilling. To prevent splashing and environmental pollution or injury to operators, the drill bit mechanism 11 is activated to drill holes in the board. At the same time, the dust collection mechanism 12 is activated to quickly suck up and treat the sawdust and dust generated during drilling through the connecting pipe at the top of the anti-splash device 9, preventing dust from spreading. Some larger sawdust falls directly into the sawdust storage box 13 at the bottom of the support base 1 for centralized collection, realizing waste classification and treatment. This solves the problems of board misalignment, sawdust splashing, and dust pollution when drilling holes in traditional systems. It not only improves the accuracy and efficiency of drilling holes in office desks, but also optimizes the working environment, reduces the difficulty of subsequent cleaning, and enhances the practicality and operational safety of the device.

[0023] For the second embodiment, please refer to... Figures 1-6Based on the first embodiment, the present invention provides a technical solution that can flexibly match plates of different widths and lengths, solving the problems of poor adaptability and easy damage to workpieces caused by traditional devices: The clamping and positioning device 5 includes a positioning base 51. The top and one side of the positioning base 51 are respectively provided with a first moving groove 52 and a second moving groove 53. The bottom of the positioning base 51 is fixedly connected to the fixed end of a first electric telescopic rod 54 through a bracket. The movable end of the first electric telescopic rod 54 is fixedly connected to a width and height clamping device 55. The side of the width and height clamping device 55 is slidably connected to the inner wall of the first moving groove 52. The part of the top of the positioning base 51 located on one side of the first moving groove 52 is fixedly connected to a fourth connecting bracket 56. The side of the fourth connecting bracket 56 is fixedly connected to a first spring 57. The side of the fourth connecting bracket 56 is fixedly connected to a first elastic top plate 58 through the first spring 57. The part of the side of the first elastic top plate 58 located on one side of the first spring 57 is fixedly connected to a guide slide 59. The side of the first elastic top plate 58 is slidably connected to the fourth connecting bracket 56 through the guide slide 59.

[0024] Two sets of first moving grooves 52 and second moving grooves 53 are provided and symmetrically distributed on the positioning base 51. Two sets of first electric telescopic rods 54 are provided and symmetrically distributed at the bottom of the positioning base 51. The inner wall of the second moving groove 53 is fixedly connected to the side of the slider inside the first electric guide rail 4.

[0025] Multiple sets of first springs 57 are evenly distributed on one side of the fourth connecting bracket 56, and two sets of guide rails 59 are symmetrically distributed on the side of the first elastic top plate 58.

[0026] In use, the basic preparation process of the first embodiment is followed. The office desk board to be processed is placed stably on the top of the support base 1. According to the specific size of the board, the first electric guide rails 4 on the two sets of first connecting brackets 2 are activated, driving the clamping and positioning devices 5 on both sides to slide along the guide rails. The distance between the two sets of devices is adjusted to reserve a suitable space for clamping the board and to adapt to the width and thickness of the board. The two sets of first electric telescopic rods 54 at the bottom of the positioning base 51 are activated. Their movable ends drive the width and height clamping devices 55 to slide left and right along the first moving groove 52, approaching and fitting the side of the board from the width direction. At the same time, the first elastic top plate 58 on one side of the fourth connecting bracket 56 at the top of the positioning base 51 is evenly distributed in multiple sets. Under the preload of the first spring 57, the plate is tightly fitted to its side along its length. The elastic deformation of the spring absorbs the clamping stress, avoiding damage to the plate surface caused by rigid contact. The two sets of guide strips 59 on the side of the first elastic top plate 58 ensure that the top plate slides smoothly along the fourth connecting bracket 56 under the action of the first spring 57. This ensures both tight clamping and adaptability to thickness differences through the adaptive deformation of the spring. The width and height clamping device 55 can flexibly match plates of different widths by sliding left and right along the first moving groove 52. This solves the problems of poor adaptability and easy damage to workpieces caused by traditional devices, optimizes the working environment, reduces subsequent cleaning costs, and makes the processing of wire holes in office desks more efficient and convenient.

[0027] Third embodiment, please refer to Figures 1-7 Based on the second embodiment, the present invention provides a technical solution that improves the accuracy and efficiency of wire hole opening and is compatible with office desk boards of different widths, lengths, and thicknesses: The width and height clamping device 55 includes a fifth connecting bracket 551. A fixed end of a first elastic telescopic rod 552 is fixedly connected to one side of the fifth connecting bracket 551. Multiple sets of the first elastic telescopic rods 552 are evenly distributed on one side of the fifth connecting bracket 551. A second elastic top plate 553 is fixedly connected to the side of the fifth connecting bracket 551 through the first elastic telescopic rods 552. A fixed end of a second electric telescopic rod 554 is fixedly connected to the top of the fifth connecting bracket 551. A sixth connecting bracket 555 is fixedly connected to the movable end of the second electric telescopic rod 554. A second elastic telescopic rod 556 is fixedly connected to the bottom of the sixth connecting bracket 555. Two sets of the second elastic telescopic rods 556 are symmetrically distributed at the bottom of the sixth connecting bracket 555. A third elastic top plate 557 is fixedly connected to the bottom of the sixth connecting bracket 555 through the second elastic telescopic rods 556.

[0028] The bottom side of the fifth connecting bracket 551 is fixedly connected to the movable end of the first electric telescopic rod 54, and the side of the fifth connecting bracket 551 is slidably connected to the inner wall of the first moving groove 52.

[0029] In use, the first electric telescopic rod 54 at the bottom of the positioning base 51 is activated, driving the fifth connecting bracket 551 of the width and height clamping device 55 to slide left and right along the first moving groove 52 until the second elastic top plate 553 approaches the side of the plate. At this time, multiple sets of first elastic telescopic rods 552 on one side of the fifth connecting bracket 551 generate elastic thrust, pushing the second elastic top plate 553 to fit tightly against the side of the plate, achieving stable clamping in the width direction and adapting to the slight unevenness of the side of the plate through elastic deformation, avoiding surface damage caused by rigid compression. At the same time, the elastic structure can absorb drilling vibration and prevent plate displacement. For plate thickness differences, the second electric telescopic rod 554 is activated, and its movable end pushes the sixth connecting bracket 555 to move vertically downward, driving the third elastic top plate 557 to the top of the plate. As the third elastic top plate 557 approaches the board, the two sets of second elastic telescopic rods 556 at the bottom of the sixth connecting bracket 555 begin to compress, forming a flexible clamp using elastic reaction force. This, combined with the bottom support structure, fixes the board from top to bottom, ensuring that thin boards do not slip and thick boards are not damaged, while also adapting to the clamping needs of boards of different thicknesses. In addition, the first elastic top plate 58 at the top of the positioning base 51, under the action of the first spring 57, further conforms to the board in the length direction, solving the problems of poor adaptability and insufficient protection of traditional clamping devices. Combined with three-dimensional clamping, it not only improves the accuracy and efficiency of wire hole opening, but also is compatible with office desk boards of different widths, lengths, and thicknesses. It is flexible in operation and convenient in maintenance, further optimizing the production and processing flow of indoor office desks.

[0030] For the fourth embodiment, please refer to [link / reference]. Figures 1-9 Based on the third embodiment, the present invention provides a technical solution that solves the problems of sawdust splashing and dust diffusion during traditional drilling, ensuring a clean working environment, improving waste disposal efficiency, and providing a certain cooling effect on the drill bit: the anti-splash device 9 includes a first connecting shell 91, a connecting ring 92 fixedly connected to the inner wall of the first connecting shell 91, a first vent 93 opened on the connecting ring 92, a second connecting shell 94 and a third connecting shell 95 fixedly connected to the bottom of the first connecting shell 91 respectively, a second spring 96 fixedly connected to the part of the bottom of the first connecting shell 91 located between the second connecting shell 94 and the third connecting shell 95, an anti-splash shell 97 fixedly connected to the bottom of the first connecting shell 91 through the second spring 96, a second vent 98 opened on the side of the anti-splash shell 97, multiple sets of the second vent 98 are provided and evenly distributed on the side of the anti-splash shell 97, and an elastic washer 99 fixedly connected to the bottom of the anti-splash shell 97.

[0031] Multiple sets of first vents 93 are provided and evenly distributed on the connecting ring 92, and multiple sets of second springs 96 are provided and evenly distributed at the bottom of the first connecting housing 91.

[0032] In use, the telescopic cylinder 8 is activated to drive the device downwards. The elastic washer 99 at the bottom of the splash guard 97 first adheres to the surface of the board. Multiple sets of second springs 96 at the bottom of the first connecting shell 91 are compressed synchronously. The elastic reaction force makes the elastic washer 99 fit tightly to the surface of the board, adapting to boards of different thicknesses. With the cooperation of the second connecting shell 94 and the third connecting shell 95, the dust and fine wood chips generated during drilling are drawn into the interior of the splash guard 97 through the second vent 98 under negative pressure. The gas is then quickly sucked in through multiple sets of first vents 93 on the connecting ring 92, and then efficiently sucked in by the dust collection mechanism through the top connecting pipe. Larger wood chips fall directly into the chip collection box for centralized collection, while also providing a certain cooling effect on the drill bit. This solves the problems of wood chip splashing and dust diffusion during traditional drilling, ensuring a clean working environment, improving waste chip disposal efficiency, and avoiding damage to the board surface caused by rigid contact. This optimizes the safety and practicality of drilling.
