[0002] Drilling machine tools refer to a general term for machinery and equipment that use tools harder and sharper than the target object to leave cylindrical holes or openings in the target object through rotary cutting or rotary extrusion. CNC drilling machines are mainly used for drilling, reaming, chamfering, and other machining operations.

[0003] During the drilling process of metal workpieces, burrs are inevitably generated at the drilled area. Therefore, in the existing technology, workers need to remove them from the machine tool and transfer them to the grinding component for grinding, which is very troublesome.

[0004] Therefore, it is necessary to provide a new type of multi-functional drilling machine for metal workpieces to solve the above-mentioned technical problems. Summary of the Invention

[0006] The present invention provides a novel multifunctional drilling machine for metal workpieces, comprising a worktable with several support legs fixed at the bottom, a bracket fixed on the worktable, a U-shaped platform fixed on the worktable, and two movable platforms symmetrically arranged on the U-shaped platform, the bottom of the movable platforms being slidably connected to the U-shaped platform; Each of the two mobile platforms is slidably provided with a mounting base above it. A placement groove is provided on one side of the mounting base. An adjustment block is slidably provided inside the placement groove. A rotating shaft is movably provided on one side of the adjustment block. A clamping plate is fixed on the rotating shaft. The bracket is equipped with a movable mounting frame, a drilling mechanism is installed on one side of the movable mounting frame, and a grinding mechanism is installed on the other side of the movable mounting frame.

[0007] In a preferred embodiment, two first slide rails are fixed at intervals on the bracket, and a movable support is fixed on one side of the movable mounting frame. The first slide rails pass through the movable support and are slidably connected to it. A transverse lead screw is movably mounted on the bracket. The transverse lead screw passes through the movable support and is threadedly connected to it. The transverse lead screw is driven by a servo motor. The movable support has two second slide rails fixed at intervals, and the two second slide rails are slidably connected to the movable mounting frame. The movable support is movably provided with a longitudinal lead screw driven by a servo motor, and the longitudinal lead screw is threadedly connected to the movable mounting frame.

[0008] In a preferred embodiment, a cylinder is provided on one side of each of the two mounting bases, the cylinder is mounted on the movable platform, and the output end of the cylinder is fixedly connected to the mounting base.

[0009] In a preferred embodiment, an adjusting threaded rod is movably disposed inside the placement slot, the adjusting threaded rod passing through the adjusting block and being threadedly connected thereto.

[0010] In a preferred embodiment, the top of the adjusting threaded rod extends out of the mounting base and is secured with a hexagonal block.

[0011] In a preferred embodiment, a worm gear is mounted on the rotating shaft, and a worm is movably mounted on one side of the adjusting block via a bearing. The worm meshes with the worm gear, and a crank is mounted on one end of the worm.

[0012] In a preferred embodiment, two translation screws are movably mounted on the U-shaped platform, and a connecting seat is fixed on one side of the mounting base. The translation screws pass through the connecting seat and are threadedly connected to it.

[0013] In a preferred embodiment, the transverse lead screw, longitudinal lead screw, adjusting threaded rod, and translation lead screw are all galvanized. The worm gear and the worm wheel are connected by a closed transmission, and the surface of the clamping plate is provided with anti-slip texture.

[0014] In a preferred embodiment, a through groove is provided on the U-shaped platform, and a coolant recovery tank is provided below the U-shaped platform.

[0015] In a preferred embodiment, the polishing mechanism includes a polishing motor and a polishing disc. An arc-shaped mounting bracket is fixed to one side of the top of the movable mounting frame, the polishing motor is mounted on the arc-shaped mounting bracket, and the polishing disc is mounted on the output end of the polishing motor.

[0016] The beneficial effects of this invention are: 1. This equipment innovatively integrates the drilling and grinding mechanisms onto the same worktable, achieving integrated operation of drilling and grinding processes. After drilling is completed, the workpiece can be moved to the grinding mechanism for subsequent processing without disassembly or transfer, simply by driving the moving table with a translation screw. This significantly reduces process changeover time and manual operation costs, effectively improving the overall processing efficiency of metal workpieces, and is especially suitable for mass production scenarios.

[0017] 2. The equipment employs a multi-stage adjustable clamping mechanism to meet the stable clamping requirements of metal workpieces of different sizes and shapes. A cylinder drives the mounting base to achieve rapid lateral approach of the clamping plates, while an adjustable threaded rod precisely adjusts the clamping plate height to fit the workpiece thickness. A worm gear drive drives the clamping plates to rotate, enabling multi-angle workpiece positioning. The combined effect of these three mechanisms gives the clamping mechanism exceptional flexibility. Simultaneously, the anti-slip texture on the clamping plate surface increases friction with the workpiece, and combined with the self-locking characteristics of the worm gear drive, it ensures that the workpiece remains stable and displacement-free during drilling and grinding, significantly improving processing stability and accuracy.

[0018] 3. The drilling mechanism's movement adjustment employs a precision transmission combination of a servo motor, lead screw, and slide rail. The transverse and longitudinal lead screws respectively drive the moving support and mounting bracket to slide along the slide rail. The servo motor provides stable driving force, the lead screw and threaded connection structure achieve precise displacement control, and the slide rail ensures smooth movement. This dual adjustment mechanism significantly improves the positioning accuracy of the drilling mechanism, meeting the requirements of high-precision drilling and effectively reducing the scrap rate caused by positioning errors.

[0019] 4. The core transmission components of the equipment (lateral lead screw, longitudinal lead screw, adjusting screw, and translation screw) are all galvanized to form a dense protective layer, which effectively resists corrosion from coolant and metal debris, reduces component rust and wear, and significantly extends the service life of the equipment. Simultaneously, the worm gear and worm wheel adopt a closed transmission design to prevent external dust and debris from entering the transmission meshing surface, ensuring long-term stability of transmission accuracy and reducing equipment maintenance frequency and costs.

[0020] 5. The equipment features a compact overall structure, a rational layout of adjustment mechanisms, and simple and clear operating procedures. The combination of multiple operating methods, including cylinder drive, servo motor control, and hand crank adjustment, allows operators to quickly complete workpiece clamping, position adjustment, and processing switching without requiring complex professional skills training. Furthermore, the integrated design reduces the number of workpiece loading and unloading operations, lowers manual labor intensity, and improves operational safety. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 ,in Figure 1 The main structure of the novel multifunctional drilling machine for metal workpieces provided by this invention is shown in stereoscopic view.

[0025] In the specific implementation process, such as Figures 1-5 As shown, a workbench 1 with several support legs 2 fixed at the bottom is included. A bracket 3 is fixed on the workbench 1. A U-shaped platform 4 is fixed on the workbench 1. Two movable platforms 5 are symmetrically arranged on the U-shaped platform 4. The bottom of the movable platform 5 is slidably connected to the U-shaped platform 4.

[0026] Each of the two movable platforms 5 has a mounting base 6 slidably mounted on top. A placement groove 7 is provided on one side of the mounting base 6, and an adjusting block 8 is slidably mounted inside the placement groove 7. A rotating shaft 9 is movably mounted on one side of the adjusting block 8, and a clamping plate 10 is fixed to the rotating shaft 9. A movable mounting frame 11 is mounted on the bracket 3. A drilling mechanism 12 is mounted on one side of the movable mounting frame 11, and a grinding mechanism is mounted on the other side. The grinding mechanism includes a grinding motor 29 and a grinding disc 30. An arc-shaped mounting frame 28 is fixed to one side of the top of the movable mounting frame 11, and the grinding motor 29 is mounted on the arc-shaped mounting frame 28. The grinding disc 30 is mounted on the output end of the grinding motor 29.

[0027] Two first slide rails 13 are fixed at intervals on the bracket 3. A movable support 15 is fixed to one side of the movable mounting frame 11. The first slide rails 13 pass through the movable support 15 and are slidably connected to it. A transverse lead screw 14 is movably mounted on the bracket 3. The transverse lead screw 14 passes through the movable support 15 and is threadedly connected to it. The transverse lead screw 14 is driven by a servo motor. Two second slide rails 16 are fixed at intervals on the movable support 15. The two second slide rails 16 are slidably connected to the movable mounting frame 11. A longitudinal lead screw 17, driven by a servo motor, is movably mounted on the movable support 15. The longitudinal lead screw 17 is threadedly connected to the movable mounting frame 11. Two translation lead screws 24 are movably mounted on the U-shaped platform 4. A connecting seat 25 is fixed to one side of the mounting base 6. The translation lead screw 24 passes through the connecting seat 25 and is threadedly connected to it. The transverse lead screw 14, the longitudinal lead screw 17, the adjusting threaded rod 19, and the translation lead screw 24 are all galvanized to improve their service life.

[0028] The worm gear 22 and worm wheel 21 employ a closed transmission. The surface of the clamping plate 10 is textured with anti-slip grooves to ensure effective clamping. During drilling, the position adjustment of the drilling mechanism 12 is achieved through dual precision transmissions. In the transverse direction, a servo motor on the support 3 drives the transverse lead screw 14 to rotate. The transverse lead screw 14 is threadedly connected to the movable support 15, and the movable support 15 slides along the first slide rail 13. Therefore, the rotation of the transverse lead screw 14 causes the movable support 15 to move laterally along the first slide rail 13, thus adjusting the transverse position of the drilling mechanism 12. In the longitudinal direction, a servo motor on the movable support drives the longitudinal lead screw 17 to rotate. The longitudinal lead screw 17 is threadedly connected to the movable mounting frame 11, and the movable mounting frame 11 slides along the second slide rail 16, thereby causing the movable mounting frame 11 to move longitudinally along the second slide rail 16, completing the longitudinal position adjustment of the drilling mechanism 12. Through coordinated adjustment in the horizontal and vertical directions, the drilling mechanism 12 can be precisely moved to the workpiece to be processed position, meeting the processing requirements of different drilling positions.

[0029] When grinding is required after drilling, the workpiece does not need to be disassembled. The workpiece is moved to the grinding mechanism via a lead screw on the girder. The lead screw inside the girder rotates under motor drive, and the connecting seat, threaded to the lead screw, is fixed to the mounting base, causing the moving table to slide along the girder, transferring the workpiece below the grinding mechanism. At this point, the grinding motor on the arc-shaped mounting frame starts, driving the grinding disc to rotate at high speed, grinding, deburring, and chamfering the drilled area of ​​the workpiece, achieving integrated drilling and grinding processing.

[0030] A cylinder 18 is installed on one side of each of the two mounting seats 6. The cylinder 18 is mounted on the moving table 5, and its output end is fixedly connected to the mounting seat 6. During the workpiece clamping stage, the operator places the metal workpiece to be processed between the two clamping plates 10 of the U-shaped table 4. The cylinder 18 on the moving table is activated, and its output end pushes the mounting seat 6 to slide along the moving table 5, bringing the two clamping plates 10 closer together, thus initially achieving lateral positioning of the workpiece. An adjusting threaded rod 19 is movably installed inside the placement groove 7. The adjusting threaded rod 19 passes through the adjusting block 8 and is threadedly connected to it. The top of the adjusting threaded rod 19 extends out of the mounting seat 6 and is fixed with a hexagonal block 20. This allows the operator to easily rotate the hexagonal block. A worm gear 21 is installed on the rotating shaft 9. A worm 22 is movably installed on one side of the adjusting block 8 via a bearing. The worm 22 meshes with the worm gear 21, and a crank 23 is installed at one end of the worm 22.

[0031] For workpieces of different thicknesses, the clamping height can be adjusted by adjusting the threaded rod: Rotating the hexagonal block 20 at the top of the threaded rod 19 causes the adjusting block 8 to move up and down along the placement groove 7 due to the threaded connection between the threaded rod 19 and the adjusting block 8, and the restricted sliding of the adjusting block 8 within the placement groove 7. This causes the rotating shaft 9 and the clamping plate 10 to rise and fall synchronously until the clamping plate 10 adapts to the workpiece thickness, ensuring clamping stability. If different angles or surfaces (such as the bottom and sides) of the workpiece need to be processed, rotating the crank 23 drives the worm gear 22 to rotate. The worm gear 22 meshes with the worm wheel 21 on the rotating shaft 9, driving the rotating shaft 9 to rotate via the worm wheel and worm gear transmission, thereby causing the workpiece clamped by the clamping plate 10 to flip. Because the worm wheel and worm gear transmission has a self-locking characteristic, the workpiece can be stably held after flipping to the target angle, preventing displacement during processing.

[0032] A through slot 26 is provided on the U-shaped table 4, and a coolant recovery tank 27 is provided below the U-shaped table 4. When grinding is required after drilling, the workpiece does not need to be disassembled. The workpiece is moved to the grinding mechanism by the translation screw 24 on the U-shaped table 4. The translation screw 24 inside the U-shaped table 4 rotates under the drive of the motor. The connecting seat 6, which is threaded to the translation screw 24, drives the moving table 5 to slide along the U-shaped table 4, moving the workpiece to the bottom of the grinding mechanism. At this time, the grinding motor 29 on the arc-shaped mounting bracket 28 starts, driving the grinding disc 30 to rotate at high speed, grinding, deburring, chamfering and other treatments on the drilled part of the workpiece, realizing integrated processing of drilling and grinding.

[0033] Throughout the entire processing, the coolant is recycled through a channel. The coolant used during drilling and grinding flows over the workpiece surface and collects through the channel 26 on the U-shaped table 4, ultimately flowing into the coolant recovery tank 27 below the U-shaped table 4, preventing direct coolant loss and achieving resource recycling. Simultaneously, the transverse lead screw 14, longitudinal lead screw 17, adjusting threaded rod 19, and translation lead screw 24 are all galvanized, effectively resisting corrosion from coolant and metal debris, extending component lifespan. The worm gear 22 and worm wheel 24 employ a closed-loop transmission, reducing the impact of external dust and debris on transmission accuracy and further ensuring equipment operational stability.

[0034] The working principle of this invention: When using this drilling machine, the operator can move the workpiece to be processed between the two clamping plates 10, start the two cylinders 18 to drive the two mounting seats 6 to move closer to each other until the two clamping plates 10 fix the workpiece. After fixing, under the transmission action of the transverse lead screw 14, longitudinal lead screw 17 and translation lead screw 24 driven by the corresponding motors, the cutter at the bottom of the drilling mechanism 12 can move in all directions, thereby completing the processing of the workpiece surface. When it is necessary to process the bottom surface of the workpiece, simply turn the rocker arm 23 to drive the worm gear 22 to rotate. Under the transmission action of the worm gear 22 and the worm wheel 21, the clamping plate 10 will rotate, thereby causing the workpiece to flip. During the processing, since the transmission of the worm gear 22 and the worm wheel 21 has self-locking properties, the workpiece will not shake during processing, ensuring the processing effect. When grinding is required after processing, the translation screw 24 can be activated to move the moving table 5 toward the grinding mechanism, eliminating the need to transfer the workpiece to the grinding equipment again, thus saving working time.
