[0004] To achieve the above objectives, the present invention adopts the following technical solution: a drilling device for the production of household appliances, comprising a workbench, a first motor disposed at the bottom of the workbench, and a transmission shaft connected to the output end of the first motor, a turntable connected to one end of the transmission shaft, and multiple sets of first fixed platforms disposed above the turntable, a cylinder disposed at the top of the first fixed platform, and a first connecting block connected to the pushing end of the cylinder, a third connecting block connected to the bottom of the first connecting block, and a fixed plate connected to one side of the third connecting block, a telescopic rod and a damper disposed on one side of the fixed plate, and a clamping plate connected to one end of the telescopic rod, a second fixed platform disposed on one side of the turntable, a fourth motor disposed at the top of the second fixed platform, and a second lead screw connected to the output end of the fourth motor, a second slider sleeved on the second lead screw, and a limit plate connected to one side of the second slider, and a lifting drilling mechanism disposed on the top side of the limit plate.

[0005] Preferably, the bottom of the first fixed platform is provided with multiple sets of second connecting blocks, each second connecting block is sleeved with a guide rail, and the guide rail passes through and connects to the first connecting block. The third connecting block is connected with a rack, and the rack meshes with a gear disk. The two sets of racks form a synchronous movement structure through the gear disk.

[0006] Preferably, the lifting and drilling mechanism includes a motor frame, and a second motor is installed at the top of the motor frame. The output end of the second motor is connected to a first lead screw. The first lead screw is sleeved with a first slider. A fixing frame is connected to one side of the first slider.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-7 This utility model provides a technical solution: a drilling device for the production of household appliances, including a workbench 1, a first motor 2 at the bottom of the workbench 1, and a transmission shaft 3 connected to the output end of the first motor 2. One end of the transmission shaft 3 is connected to a turntable 4, and multiple sets of first fixed platforms 5 are arranged above the turntable 4. A cylinder 6 is arranged at the top of the first fixed platform 5, and a first connecting block 7 is connected to the pushing end of the cylinder 6. A third connecting block 10 is connected to the bottom of the first connecting block 7, and a fixing plate 13 is connected to one side of the third connecting block 10. A telescopic rod 14 and a damper 15 are arranged on one side of the fixing plate 13, and a clamping plate 1 is connected to one end of the telescopic rod 14. 6. A second fixed platform 35 is provided on one side of the turntable 4. A fourth motor 26 is provided at the top of the second fixed platform 35. The output end of the fourth motor 26 is connected to a second lead screw 27. The second lead screw 27 is sleeved with a second slider 28. A limit plate 29 is connected to one side of the second slider 28. A lifting and drilling mechanism is provided on the top side of the limit plate 29. Multiple sets of second connecting blocks 8 are provided at the bottom of the first fixed platform 5. The second connecting blocks 8 are sleeved with guide rails 9. The guide rails 9 pass through and connect to the first connecting blocks 7. A third connecting block 10 is connected to a rack 11. The rack 11 is meshed with a gear disk 12. The two sets of racks 11 form a synchronous movement structure through the gear disk 12.

[0025] In specific implementation: When clamping and fixing the workpiece, the workpiece is first manually placed into the slot inside the turntable 4. At this time, the movement of the cylinder 6 drives the first connecting block 7 connected to its push end to move. Since the second connecting block 8 at the bottom of the first fixed platform 5 is sleeved on the guide rail 9, and the guide rail 9 passes through and connects to the first connecting block 7, the first connecting block 7 can slide stably along the guide rail 9 during movement, ensuring the linearity and stability of the movement. When the first connecting block 7 moves horizontally, it drives the third connecting block 10 connected at the bottom to move together. The third connecting block 10 is connected to a rack 11, and the two sets of third connecting blocks 10 have different structures. One set is hollow, allowing the rack 11 to move within it, while the other set is solid, used to drive the connected rack 11 to move. The two sets of racks 11 form a synchronous movement structure through the meshing gear disk 12 in the middle. When one side of the rack 11 moves with the third connecting block 10, it will drive the other side of the rack 11 to move synchronously in the opposite direction through the gear disk 12. The movement of bar 11 causes the connected fixed plate 13 to move, and the telescopic rod 14 and damper 15 on one side of the fixed plate 13 also move accordingly. The V-shaped clamping plate 16 connected to one end of the telescopic rod 14 gradually approaches the workpiece under the synergistic action of the telescopic rod 14 and the damper 15. The damper 15 plays a role in buffering and stabilizing, avoiding large impacts when the clamping plate 16 approaches the workpiece, and improving the vibration elimination effect for subsequent drilling work. At the same time, it ensures a smooth clamping process. The clamping plates 16 on both sides clamp the workpiece symmetrically from both sides. Through the above operation, the workpiece clamping work can be easily completed.

[0026] Please refer to Figures 1-4 The lifting and drilling mechanism includes a motor frame 17, with a second motor 18 mounted on the top of the motor frame 17. The output end of the second motor 18 is connected to a first lead screw 19, which is sleeved with a first slider 20. A fixed frame 34 is connected to one side of the first slider 20, and a third motor 22 is mounted on the top of the fixed frame 34. A drill bit 33 is connected to the output end of the third motor 22. A slide rail 21 is connected to one side of the vertical surface of the workbench 1, and the first slider 20 is sleeved on the outer side of the slide rail 21. A limit block 32 is provided on the side of the slide rail 21 near the bottom. A ring-shaped vacuum cleaner 23 is provided at the bottom of the fixed frame 34, and a first dust collection box 25 is provided on one side of the fixed frame 34. A hose 24 is connected to the bottom of the first dust collection box 25, and one end of the hose 24 is connected to the vacuum cleaner 23. A funnel 30 is provided at the bottom of the turntable 4, and the funnel 30 is mounted on the top of the workbench 1. A second dust collection box 31 is provided at the bottom of the workbench 1, and the bottom of the second dust collection box 31 corresponds to the bottom of the funnel 30.

[0027] In specific implementation: When drilling the workpiece, after the above-mentioned clamping process, the rotation of the first motor 2 drives the transmission shaft 3 to rotate, which in turn drives the turntable 4 to rotate, bringing the workpiece below the lifting and drilling mechanism. Then, the fourth motor 26 is started, and its output drives the second lead screw 27 to rotate. The second slider 28, sleeved on the second lead screw 27, moves along the lead screw direction, thereby moving the connected limiting plate 29. The limiting plate 29 then presses the workpiece, making it more stable during drilling. The rotation of the second motor 18 drives the first lead screw 19 at its output to rotate. The first slider 20, sleeved on the first lead screw 19, moves up and down along the slide rail 21 on one side of the worktable 1 under the drive of the lead screw. A fixed frame 34 is connected to one side of the first slider 20, so the fixed frame 34 rises and falls synchronously with the first slider 20. During this process, the slide rail 21 acts as a guide... The first motor 22 ensures the vertical lifting and lowering of the fixed frame 34, while the limiting block 32 near the bottom of the slide rail 21 prevents the first slider 20 from sliding down excessively and causing equipment damage. When the fixed frame 34 lowers the drill bit 33 to the appropriate position, the third motor 22 is activated, and the drill bit 33 at the output end of the third motor 22 begins to rotate at high speed to drill the workpiece. During the drilling process, the annular vacuum cleaner 23 at the bottom of the fixed frame 34 starts synchronously to promptly remove the debris generated during drilling. The debris enters the first dust collection box 25 through the hose 24. At the same time, the funnel 30 at the bottom of the turntable 4 and the second dust collection box 31 at the bottom of the worktable 1 collect the debris that falls after drilling, keeping the working area clean. After drilling one hole, the second motor 18 reverses, causing the first lead screw 19 to drive the fixed frame 34 and drill bit 33 to rise and reset. The first motor 2 drives the transmission shaft 3 and the turntable 4 to rotate, transferring the next workpiece to be drilled to the drilling position to continue the drilling operation. Through the above operation, the drilling of workpieces can be facilitated.

[0028] 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.
