Description

Technical Field

[0001] This utility model relates to the field of drilling technology, and in particular to a drilling device for furniture manufacturing. Background Technology

[0002] In furniture manufacturing, drilling devices are primarily used to machine holes in panel furniture components for installing various connectors or for positioning. These holes are indispensable parts of furniture assembly, such as screw fixing points and tenon joints. Drilling devices ensure that the precision and position of these holes meet design requirements, thereby improving the overall quality and lifespan of the furniture.

[0003] In the prior art, the surface of curved or polygonal sheet materials is usually a non-planar structure. If a hole is drilled directly vertically, the contact point of the drill bit may shift due to the change in the curvature angle, resulting in the actual hole position not matching the design position. Therefore, we propose a drilling device for furniture manufacturing to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a drilling device for furniture manufacturing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A mounting plate is fixedly connected to the outer wall of the moving end of the second linear motor. A hollow disc and a servo motor are fixedly connected to the outer wall of the mounting plate. A worm gear is fixedly connected to the outer wall of the output shaft of the servo motor. A shaft is rotatably connected inside the disc. A worm wheel is fixedly sleeved on the outer wall of the shaft, and the worm wheel meshes with the worm. One end of the shaft passes through the outer wall of the disc and is fixedly connected to a U-shaped frame. A rodless cylinder is fixedly connected to the outer wall of the U-shaped frame.

A limiting component is provided on the top of the worktable. A placement platform is fixedly connected to the top of the U-shaped platform, and a support component is provided on the outer wall of the placement platform.

[0007] Preferably, the limiting component includes a lifting platform, the top of the output end of the dual-axis cylinder is fixedly connected to the bottom of the lifting platform, the outer wall of the lifting platform has two strip grooves, the inner walls of the two strip grooves are slidably connected to moving rods, the outer walls of the two moving rods are fixedly fitted with two sliding pads, and the tops of the two moving rods are fixedly connected to limiting pads. The limiting component is used to fix the position of the board material used for furniture manufacturing.

[0008] Preferably, the support assembly includes four long rods, and the outer wall of the placement platform has four long holes. The inner walls of the four long holes are slidably connected to the outer walls of the four long rods, and each of the four long rods is fixedly connected to an extension support plate in pairs. The support assembly is used to support the board material used for furniture manufacturing.

[0009] Preferably, the outer wall of the disk has a circular hole, and the inner wall of the circular hole is rotatably connected to the outer wall of the output shaft of the servo motor. By setting the servo motor to drive the worm to rotate, the worm wheel will be driven to rotate. When the lead angle between the worm and the worm wheel is less than the friction angle, it has self-locking properties during transmission.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1-5 As shown, a drilling device for furniture manufacturing is disclosed, comprising a workbench 1, which serves as the basic platform for the device. The workbench 1 is welded from high-strength steel plates, and its surface is ground to ensure flatness. Two first linear motors 2 are fixedly connected to the outer walls of both sides of the workbench 1. The outer walls of the moving ends of the two first linear motors 2 are fixedly connected to the same frame 3. The two first linear motors 2 are symmetrically fixed on both sides of the workbench 1 and drive the frame 3 along the X-axis via high-precision guide rails. A second linear motor 4 is fixedly connected to the outer wall of the frame 3. A mounting plate 5 is fixedly connected to the outer wall of the moving end of the second linear motor 4. The second linear motor 4 drives the mounting plate 5 to move along the Y-axis.

[0023] A hollow disk 8 and a servo motor 6 are fixedly connected to the outer wall of the mounting plate 5. A circular hole is opened on the outer wall of the disk 8. The inner wall of the circular hole is rotatably connected to the outer wall of the output shaft of the servo motor 6. A worm gear 7 is fixedly connected to the outer wall of the output shaft of the servo motor 6. The shaft body is rotatably connected inside the disk 8. A worm wheel 9 is fixedly sleeved on the outer wall of the shaft body. The worm wheel 9 and the worm gear 7 are meshed. The servo motor 6 drives the worm gear 7 to rotate, converting the horizontal rotation into vertical axial rotation. The output shaft of the servo motor 6 is equipped with an encoder to detect the rotation angle of the output shaft of the servo motor 6.

[0024] One end of the shaft penetrates the outer wall of the disc 8 and is fixedly connected to a U-shaped frame 19. A rodless cylinder 20 is fixedly connected to the outer wall of the U-shaped frame 19. A DC motor 21 is fixedly connected to the outer wall of the output end of the rodless cylinder 20. The rodless cylinder 20 is used to drive the DC motor 21. A drill bit is fixedly connected to the bottom of the output shaft of the DC motor 21. A U-shaped table 10 and a dual-axis cylinder 11 are fixedly connected to the top of the worktable 1. A placement platform 16 is fixedly connected to the top of the U-shaped table 10.

[0025] The top of the workbench 1 is equipped with a limiting component, which includes a lifting platform 12. The top of the output end of the dual-axis cylinder 11 is fixedly connected to the bottom of the lifting platform 12. The outer wall of the lifting platform 12 has two strip grooves. The inner wall of each of the two strip grooves is slidably connected to a moving rod 13. The dual-axis cylinder 11 pushes the lifting platform 12 to move up and down. The strip grooves on the lifting platform 12 allow the moving rod 13 to be manually slidably adjusted in distance. The outer wall of each of the two moving rods 13 is fixedly fitted with two sliding pads 14. The top of each of the two moving rods 13 is fixedly connected to a limiting pad 15. The bottom of each of the two limiting pads 15 is fixedly embedded with a rubber block (polyurethane material). The sheet material is flexibly fixed by pneumatic pressing to avoid indentation.

[0026] The outer wall of the placement platform 16 is provided with a support assembly, which includes four long rods 17. The outer wall of the placement platform 16 has four long holes. The inner walls of the four long holes are slidably connected to the outer walls of the four long rods 17 respectively. Each of the four long rods 17 is fixedly connected to an extension support plate 18 in pairs. The extension support plate 18 is slidably connected to the long holes of the placement platform 16 through the long rods 17. The support range can be expanded by manually stretching it.

[0027] Working principle: During use, the furniture manufacturing board is placed on top of the placement platform 16. Depending on the length of the board, the extension support plates 18 on both sides of the placement platform 16 move outwards to extend the support distance, facilitating subsequent drilling. Two moving rods 13 move along the two strip grooves, positioning the two limiting pads 15 at the top of both ends of the board. The dual-axis cylinder 11 rotates, driving the lifting platform 12 downwards. The downward movement of the lifting platform 12 drives the two moving rods 13 downwards, thereby pressing the two rubber pads at the bottom of the two limiting pads 15 against both ends of the board for position fixation. This positional fixation is achieved during the oblique hole drilling process. Linear motor 2 and second linear motor 4 operate to change the left-right and front-back directions, changing the position of mounting plate 5 so that the drill bit is positioned above the part of the sheet metal to be drilled. Servo motor 6 drives worm gear 7 to rotate, which in turn drives worm wheel 9 to rotate. Worm wheel 9 then drives shaft and U-shaped frame 19 to rotate. U-shaped frame 19 then drives rodless cylinder 20 and DC motor 21 to rotate. After rotating a certain angle, servo motor 6 stops, causing the drill bit to tilt to meet the drilling angle requirements of different sheet metals (e.g., curved or polygonal sheet metals). Rodless cylinder 20 drives DC motor 21 to move downwards, working in conjunction with the drill bit rotation to drill holes in the sheet metal.
