Description

Technical Field

[0001] This utility model relates to the field of drilling positioning technology, and in particular to a drilling device that facilitates positioning. Background Technology

[0002] Drilling is a key process that uses a high-speed rotating drill bit to feed along the axis and cut through solid materials such as metal, wood, and plastic to precisely create circular holes. It is widely used in fields such as machinery manufacturing, building installation, and electronic assembly. Its core lies in selecting the appropriate drill bit and cutting parameters according to the material properties, and coordinating with cooling and lubrication to ensure hole diameter accuracy and surface quality. It is an important basic process for realizing the connection, positioning, and function of parts.

[0003] Existing wood processing workbenches are limited in width and length. When processing large-sized wood boards, the long side is prone to warping or the ends to droop due to its own weight. This causes the drilling equipment to shift position due to unstable support when it comes into contact with the wood board, affecting drilling accuracy. At the same time, although the chip removal grooves on the workbench can accommodate the drill bit, the concentrated downward pressure of the drill bit during drilling can easily cause stress concentration on the edge of the groove, which can lead to cracking or chipping at the drilling location. This seriously affects the processing quality and the yield of finished products. Therefore, a drilling device that is easy to position is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing wood processing workbenches, which are limited in width and length. When processing large-sized wood boards, the long side is prone to warping or the ends to droop due to their own weight, causing the drilling equipment to shift position due to unstable support when in contact with the wood board, thus affecting drilling accuracy. At the same time, although the chip removal groove on the workbench can accommodate the drill bit, the concentrated downward pressure of the drill bit during the drilling process can easily cause stress concentration on the edge of the groove, leading to cracking or chipping at the drilling position. Therefore, this invention proposes a drilling device that is easy to position.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A drilling device for easy positioning, including a worktable; A support frame is fixedly connected to one end of the workbench surface. A processing plate is slidably connected to the support frame. An electric push rod is fixedly connected to the processing plate. A drilling device is fixedly connected to the end of the electric push rod. A positioning component is provided on a support frame. The positioning component includes a bidirectional threaded rod rotatably provided on the support frame, a connecting rod 1 movably provided below the bidirectional threaded rod, and a fixed plate fixedly provided at the end of the connecting rod 1 and driven by the bidirectional threaded rod and the connecting rod 1 to achieve up and down movement. A slider is slidably connected in a groove on the worktable. A support block is slidably connected to the slider. A spring is fixedly connected inside the slider and the spring is fixedly connected to the support block. A connecting rod is fixedly installed between the processing plate and the slider. Support components, located at the bottom of the worktable, are used to extend the worktable.

[0006] The above solution utilizes positioning components to fix the side of the wooden board on the workbench that needs drilling, improving the stability of the drilling position. The drilling equipment is moved along the support frame by the processing plate to adjust the drilling position. An electric push rod brings the drilling equipment into contact with the wooden board for drilling. The support block on the workbench is compressed back into the slider by the wooden board and becomes flush with the workbench. A spring returns the support block, ensuring it remains in contact with the wooden board. Connecting rod two allows the support block to move with the drilling equipment, ensuring continuous force on the bottom of the wooden board during drilling, counteracting the downward drilling force and preventing cracking at the drilling location. Furthermore, the support components expand the support range of the workbench, improving drilling accuracy.

[0007] In a preferred embodiment, a motor is fixedly connected to one side of the support frame, and a threaded rod is fixedly connected to the end of the output shaft of the motor. The threaded rod is rotatably connected to the support frame and threadedly connected to the processing plate.

[0008] Using the above scheme, the starting drive of motor one rotates the threaded rod, and through the threaded connection between the processing plate and the threaded rod, the drilling equipment moves in a plane to select the drilling position on the wooden board.

[0009] In a preferred embodiment, the surface of the support block is provided with a groove, and the groove of the support block is coaxial with the drill rod of the drilling equipment.

[0010] Using the above solution, the drilling equipment drills holes in the wooden board and passes through the board. The groove of the support block reduces the contact between the drill bit and the support block after the drill bit passes through the board, thus increasing the service life of the drill bit.

[0011] In a preferred embodiment, the positioning component further includes a connecting plate fixedly connected to the support frame. A second motor is fixedly connected to one side of the connecting plate. The output shaft end of the second motor is fixedly connected to a bidirectional threaded rod. The bidirectional threaded rod is rotatably connected to the connecting plate. A movable block is threadedly connected to the bidirectional threaded rod. The movable block is slidably connected to the support frame. The movable block is movably connected to a first connecting rod via a shaft. A U-shaped connecting block is movably connected to the end of the first connecting rod away from the movable block via a shaft. The U-shaped connecting block is fixedly connected to the fixed plate.

[0012] Using the above scheme, the starting drive of motor two drives the bidirectional threaded rod to rotate, causing the moving block to move relative to each other, which in turn drives the two connecting rods one to move the fixed plate toward the surface of the worktable through the U-shaped connecting block, thus fixing and positioning one side of the wooden board placed on the worktable.

[0013] In a preferred embodiment, the support further includes a housing fixedly connected to the bottom of the workbench, a support rod slidably connected to the housing, a support plate fixedly connected to the end of the support rod, a plurality of ball bearings rollingly connected to the support plate, and a pin penetrating the housing and inserted into a plurality of slots opened on the support rod.

[0014] By adopting the above scheme, the support plate is pulled outward, and the support plate drives the support rod to slide outward on the casing, so that the support plate is away from the side of the worktable, expanding the surface of the worktable and improving the stability of the large wooden board during drilling. In addition, the arrangement of multiple ball bearings on the support plate reduces friction when the wooden board moves on the worktable, making it easier to move the wooden board.

[0015] In a preferred embodiment, the number of the support members is three sets, located at the front and left and right sides of the bottom of the worktable, and the ball bearings are arranged flush with the surface of the worktable.

[0016] By adopting the above solution, the surface of the workbench is expanded in multiple ways, providing comprehensive support for large wooden boards, improving the stability of board positioning, and enhancing drilling accuracy.

[0017] This utility model has the following beneficial effects: 1. In this utility model, the fixed plate is driven to press down by the bidirectional threaded rod in the positioning component, which accurately fixes the edge of the wooden board and effectively prevents the wooden board from shifting or tilting during drilling, thus greatly improving the positioning stability. The support component adopts an expandable support plate design, which is flush with the worktable by ball bearings. This not only allows for flexible adjustment of the support range to adapt to wooden boards of different sizes, reducing the risk of the wooden board falling or cracking at both ends during drilling, but also uses ball bearings to reduce friction and facilitate the movement of the wooden board. The synergistic effect of the two significantly enhances the overall stability of the wooden board processing, ensuring accurate drilling position and complete edges, and comprehensively improving processing quality and finished product qualification rate.

[0018] 2. In this utility model, the support block achieves adaptive rebound through the spring, always keeping close to the bottom of the wooden board, effectively dispersing the concentrated stress generated by the drill bit pressing down during drilling, and preventing the wooden board from cracking at the chip removal groove; its groove design is coaxial with the drill bit, which not only reduces frictional wear when the drill bit passes through and extends tool life, but also ensures that the support block can accurately follow the movement of the drilling equipment through the connecting rod two, continuously providing stable support force, thus solving the problem of edge cracking in wooden board processing.

[0021] Example 1. For example... Figures 1-5 As shown, the present invention proposes a drilling device for easy positioning, including a worktable 1; Support frame 2 is fixedly connected to one end of the surface of workbench 1. Processing plate 5 is slidably connected to support frame 2. Electric push rod 6 is fixedly connected to processing plate 5. Drilling equipment 7 is fixedly connected to the end of electric push rod 6. Positioning component 23 is provided on support frame 2. Positioning component 23 includes a bidirectional threaded rod 9 rotatably provided on support frame 2, a connecting rod 11 relatively movably provided below bidirectional threaded rod 9, and a fixed plate 13 fixedly provided at the end of connecting rod 11 and driven by bidirectional threaded rod 9 and connecting rod 11 to achieve up and down movement. The slider 14 is slidably connected in the groove opened on the worktable 1. A support block 15 is slidably connected to the slider 14. A spring 17 is fixedly connected inside the slider 14 and the spring 17 is fixedly connected to the support block 15. A connecting rod 16 is fixedly installed between the processing plate 5 and the slider 14. Support component 24, located at the bottom of workbench 1, is used to extend workbench 1. Positioning component 23 is used to fix the side of the wooden board on workbench 1 that needs to be drilled, improving the stability of the drilling position of the drilling equipment 7. The drilling equipment 7 is slidably adjusted on support frame 2 by processing plate 5, and the drilling position is adjusted by electric push rod 6. The drilling equipment 7 contacts the wooden board for drilling. When the wooden board is placed on workbench 1, support block 15 is compressed back into slider 14 and flush with workbench 1 by the wooden board. Spring 17 rebounds support block 15, keeping support block 15 in contact with the wooden board. The support block 15 moves with drilling equipment 7 through connecting rod 2 16, so that the drilling equipment 7 continuously exerts force on the bottom of the wooden board through support block 15 during the drilling process, counteracting the downward drilling force of drilling equipment 7 and preventing cracking at the drilling position of the wooden board. Support component 24 also expands the range of support of workbench 1 for wooden board, improving drilling accuracy.

[0022] A motor 3 is fixedly connected to one side of the support frame 2. A threaded rod 4 is fixedly connected to the end of the output shaft of the motor 3. The threaded rod 4 is rotatably connected to the support frame 2 and threadedly connected to the processing plate 5. The start of the motor 3 drives the threaded rod 4 to rotate. Through the threaded connection between the processing plate 5 and the threaded rod 4, the drilling device 7 moves in a plane to select the drilling position on the wooden board.

[0023] The surface of the support block 15 is provided with a groove. The groove of the support block 15 is coaxial with the drill rod of the drilling device 7. The drilling device 7 drills holes in the wooden board and passes through the wooden board. The groove of the support block 15 reduces the contact between the drill bit on the drilling device 7 and the support block 15 after passing through the wooden board, thereby increasing the service life of the drill bit.

[0024] The positioning component 23 also includes a connecting plate that is fixedly connected to the support frame 2. A motor 2 8 is fixedly connected to one side of the connecting plate. The output shaft end of the motor 2 8 is fixedly connected to the bidirectional threaded rod 9. The bidirectional threaded rod 9 is rotatably connected to the connecting plate. A movable block 10 is threadedly connected to the bidirectional threaded rod 9. The movable block 10 is slidably connected to the support frame 2. The movable block 10 is movably connected to the connecting rod 11 via a shaft. The end of the connecting rod 11 away from the movable block 10 is movably connected to a U-shaped connecting block 12 via a shaft. The U-shaped connecting block 12 is fixedly connected to the fixed plate 13. The start of the motor 2 8 drives the bidirectional threaded rod 9 to rotate, causing the movable block 10 to move relative to the other side. This causes the two connecting rods 11 to move the fixed plate 13 toward the surface of the workbench 1 via the U-shaped connecting block 12, thus fixing and positioning one side of the wooden board placed on the workbench 1.

[0025] The support member 24 also includes a housing 18 fixedly connected to the bottom of the workbench 1. A support rod 20 is slidably connected to the housing 18. A support plate 21 is fixedly connected to the end of the support rod 20. Multiple balls 22 are slidably connected to the support plate 21. A pin 19 is connected through the housing 18 and inserted into multiple slots on the support rod 20. Pulling the support plate 21 outward causes the support rod 20 to slide outward in the housing 18, so that the support plate 21 moves away from the side of the workbench 1, expanding the surface of the workbench 1 and improving the stability of the large wooden board during drilling. The arrangement of multiple balls 22 on the support plate 21 reduces friction when the wooden board moves on the workbench 1, making it easier to move the wooden board.

[0026] There are three sets of support members 24, located at the front and left and right sides of the bottom of the workbench 1. The ball bearings 22 are arranged flush with the surface of the workbench 1, so that the surface of the workbench 1 can be expanded in multiple ways to achieve comprehensive support for large wooden boards, improve the stability of wooden board positioning, and improve the accuracy of drilling.

[0027] In this embodiment, when processing the wooden board, the board is first placed on the workbench 1, with the side of the board to be processed positioned closer to the support frame 2. After adjusting the position for drilling, the bidirectional threaded rod 9 is driven to rotate in both directions by the start of motor 2 8. The rotation of the bidirectional threaded rod 9 drives two moving blocks 10 to move relative to each other. When the two moving blocks 10 are close to each other, the two connecting rods 11 push the U-shaped connecting block 12 downwards. The U-shaped connecting block 12 then drives the fixing plate 13 to fix and position the side of the wooden board that has been adjusted. At this time, the threaded rod 4 is driven to rotate in both directions by the start of motor 3 3. Through threaded connection with the processing plate 5, the processing plate 5 is positioned... The support frame 2 moves left and right on the plane, so that the drilling equipment 7 moves with it. The drilling equipment 7 is adjusted to the position where the hole needs to be drilled. The electric push rod 6 pushes the drilling equipment 7 to move down and drill a hole in the wooden board. When the drill bit at the end of the drilling equipment 7 contacts the wooden board, it will squeeze the wooden board. The support block 15, which is squeezed and retracted inside the slider 14, is kept in contact with the bottom of the wooden board by the rebound of the spring 17. The downward squeezing force of the drilling equipment 7 is resisted by the support block 15 to prevent the wooden board from cracking due to the squeezing of the drill bit at the drilling position. The support block 15 moves with the drilling equipment 7 through the connecting rod 16, so that the support block 15 is always in the axial position of the drilling equipment 7. When processing large wooden boards, the support plate 21 is pulled outward by pulling out the pin 19 inserted into the casing 18 and the support rod 20. The support plate 21 drives the support rod 20 to slide inside the casing 18. The position of the support plate 21 is adjusted according to the size of the wooden board. It is then fixed by inserting the pin 19 into the casing 18 and the support rod 20, which supports the wooden board and prevents one side from warping or both ends from sagging during processing if the wooden board is too large. This also improves the accuracy of drilling positioning and prevents drilling cracks.
