Whether drilling mortises in furniture or installing decorative parts, it ensures accurate drill bit positioning, resulting in neat and standardized holes. This significantly improves drilling efficiency and quality, reduces errors and material waste, making it an invaluable aid for woodworking precision tasks.

[0003] According to Chinese Patent No. CN210121888U, a woodworking drilling jig includes: a base, a fixed jaw on the base, a horizontally sliding slide on the base, a vertically sliding movable jaw on the slide, the movable jaw including an obliquely arranged guide hole for receiving and guiding a drill bit; a sliding slide, the movable jaw being able to move towards or away from the fixed jaw; a sliding movable jaw, the movable jaw being able to rise or fall on the slide, a locking mechanism being provided between the slide and the movable jaw, the locking mechanism fixing the movable jaw and the slide together; a screw rotatably mounted on the base, a nut slidably mounted on the base, the nut being threadedly connected to the screw, a rocker plate rotatably mounted on the nut, the rocker plate having a force-reducing end and a force-saving end respectively at both ends, rotating the screw causes the nut to cause the force-reducing end to abut against the slide, simultaneously causing the movable jaw to slide towards the fixed jaw.

[0004] In the above solution, the drilling tool makes holes in the wooden board through a guide hole, which still has the following disadvantages: when the drill bit of the drilling tool is making a hole in the wooden board, the drill bit on the drilling tool may wobble when applying force to the wooden board, affecting the accuracy of making the hole in the wooden board. Utility Model Content

[0005] The purpose of this invention is to provide a positioning fixture for a woodworking drill to solve the problem that the drill bit on the drilling tool may wobble when applying force to the wood board, affecting the accuracy of drilling the hole in the wood board.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a positioning fixture for a woodworking drill, including a connecting plate, the connecting plate being disposed below the drill, two fixing plates being fixed to the surface of the drill's output shaft, a drill bit being inserted into the drill's output shaft, a sleeve hole being formed on the top surface of the connecting plate, the drill bit being slidably inserted into the sleeve hole, two limiting grooves being formed on the inner wall of the sleeve hole, two limiting plates being fixed to the surface of the drill bit, the limiting grooves being slidably disposed with the limiting plates, two fixing bolts being inserted into the connecting plate, the top ends of the fixing bolts passing through the fixing plates and threadedly connected to nuts.

[0007] Preferably, a workbench is provided below the drilling rig, a cylinder is fixed on the top surface of the workbench, a lifting baffle is fixed at the top of the cylinder telescopic rod, and the top surface of the lifting baffle is fixed to the bottom surface of the drilling rig.

[0008] Preferably, a plurality of stabilizing rods are fixed on the top surface of the cylinder, and the stabilizing rods are slidably inserted into the lifting baffle.

[0009] Preferably, a positioning plate is fixed on the top surface of the workbench, a threaded rod is threadedly connected to the positioning plate, a pressing plate is provided at one end of the threaded rod, a fixing ring is fixed on one side of the pressing plate, a bearing is provided inside the fixing ring, and the surface of one end of the threaded rod is fixed to the inner wall surface of the bearing inner ring.

[0010] Preferably, the top surface of the workbench is provided with a sliding opening, and the bottom surface of the extrusion plate is fixed with a sliding plate, and the sliding opening and the sliding plate are slidably arranged.

[0011] Preferably, the top surface of the workbench has several mounting openings, and the interior of each mounting opening is equipped with rotatable rollers.

[0012] Compared with existing technologies, a positioning fixture for a woodworking drill that adopts the above-mentioned technical solution has the following advantages:

[0013] 1. By using the matching of the limiting groove and the corresponding size limiting plate, where the height of the limiting plate is greater than the depth of the limiting groove, and the mutual pressing and fixing of the connecting plate and the fixing plate, different drill bits can be clamped and fixed at the bottom of the drill output shaft, reducing the shaking amplitude of the drill bit during operation.

[0014] 2. When the wooden board slides on the top surface of the workbench, the bottom surface of the board will contact the surface of the roller. The rotation of the roller reduces the friction of the board when it slides. When the board moves to the bottom of the drill to prepare for drilling, the operator will first rotate the threaded rod. The threaded connection between the threaded rod and the positioning plate will drive the pressing plate to approach the board and apply a pressing force to the board, which increases the stability of the board when drilling.

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-3 As shown, a positioning fixture for a woodworking drill includes a connecting plate 1, which is located below a drill rig 2. Two fixing plates 3 are fixed to the surface of the output shaft of the drill rig 2. A drill bit 4 is inserted into the output shaft of the drill rig 2. A sleeve hole 5 is opened on the top surface of the connecting plate 1. The drill bit 4 is slidably inserted into the sleeve hole 5. Two limiting grooves 6 are opened on the inner wall of the sleeve hole 5. Two limiting plates 7 are fixed to the surface of the drill bit 4. The limiting grooves 6 and the limiting plates 7 are slidably arranged. Two fixing bolts 8 are inserted into the connecting plate 1. The top of the fixing bolts 8 passes through the fixing plate 3 and is threaded with a nut 9. A workbench 10 is provided below the drill rig 2. A cylinder 11 is fixed to the top surface of the workbench 10. A lifting baffle 12 is fixed to the top of the telescopic rod of the cylinder 11. The top surface of the lifting baffle 12 is fixed to the bottom surface of the drill rig 2. Several stabilizing rods 13 are fixed to the top surface of the cylinder 11. The stabilizing rods 13 are slidably inserted into the lifting baffle 12.

[0022] During use, when drilling, the wooden board is placed on the top surface of the workbench 10. Then, the telescopic rod of the cylinder 11 retracts, causing the lifting folding plate 12 to descend synchronously, which in turn brings the drill bit 4 close to the wooden board. The rotating drill bit 4 is used to drill holes in the wooden board. After drilling the holes in the wooden board, the telescopic rod of the cylinder 11 extends, causing the lifting folding plate 12 and the drill bit 4 to rise synchronously, so that the drill bit 4 is detached from the wooden board. When drilling holes of different diameters in the wooden board, the nut 9 and the fixing bolt 8 can be removed first, and then the connecting plate 1 and the fixing plate 3 can be separated. The drill bit 4 can then be pulled out from above the connecting plate 1 and replaced.

[0023] By cooperating with the limiting groove 6 and the corresponding size limiting plate 7, where the height of the limiting plate 7 is greater than the depth of the limiting groove 6, and by the mutual pressing and fixing of the connecting plate 1 and the fixing plate 3, different drill bits 4 can be clamped and fixed at the bottom of the output shaft of the drilling machine 2, reducing the shaking amplitude of the drill bit 4 during operation.

[0024] like Figure 2 and Figure 4 As shown, a positioning plate 14 is fixed on the top surface of the workbench 10. A threaded rod 15 is threadedly connected to the positioning plate 14. A pressing plate 16 is provided at one end of the threaded rod 15. A fixing ring 17 is fixed on one side of the pressing plate 16. A bearing is provided inside the fixing ring 17. The surface of one end of the threaded rod 15 is fixed to the inner wall of the inner ring of the bearing. A sliding opening 18 is provided on the top surface of the workbench 10. A sliding plate 19 is fixed on the bottom surface of the pressing plate 16. The sliding opening 18 and the sliding plate 19 are slidably arranged. Several mounting openings 20 are provided on the top surface of the workbench 10. Rollers 21 are rotatably arranged inside the mounting openings 20.

[0025] During use, when the wooden board slides on the top surface of the workbench 10, the bottom surface of the wooden board will contact the surface of the roller 21. The rotation of the roller 21 reduces the friction of the wooden board when sliding. When the wooden board moves to the bottom of the drill 2 to prepare for drilling, the operator will first rotate the threaded rod 15. The threaded connection between the threaded rod 15 and the positioning plate 14 will drive the pressing plate 16 to approach the wooden board and apply a pressing force to the wooden board, which increases the stability of the wooden board when drilling.

[0026] 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.
