Description

Technical Field

[0001] This utility model relates to the field of furniture processing technology, and in particular to a seat frame drilling machine. Background Technology

[0002] A chair consists of several parts, with the seat being the main component, the seat frame. This frame serves as the foundation, connecting the backrest, armrests, and legs to form a complete chair. The seat is typically connected to the armrests and legs using bolts or other hardware. This requires precise drilling into the seat. Currently, the common method is to manually measure and mark the drilling positions on the seat frame, then hold the frame and mill the holes one by one using a drilling machine. However, this method is prone to positioning errors in the drilled holes, affecting the strength of the connection and the stability of the chair. It also increases the probability of rework, reducing overall work efficiency. Furthermore, the repetitive manual work is tiring and can easily cause worker fatigue, further increasing the possibility of errors. Additionally, the seat frame is relatively heavy and inconvenient to hold. Summary of the Invention

[0003] To address the aforementioned problems, the present invention aims to provide a frame drilling machine that can position and lock the frame on the worktable, thereby improving the drilling accuracy of the frame. Simultaneously, it can drill multiple holes on the frame at the same time, thus increasing drilling efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A frame drilling machine, characterized in that it includes a frame, a worktable mounted on the frame, a frame fixing mechanism, and a frame drilling mechanism, wherein...

[0006] The workbench is fixedly mounted on the operating table of the machine frame, and is suitable for positioning and supporting the seat frame;

[0007] The seat frame fixing mechanism is set on the worktable and located on the outside of the seat frame, which is suitable for locking the seat frame on the worktable;

[0008] The frame drilling mechanism includes multiple drilling devices disposed on the outside of multiple sets of worktables. Each drilling device includes a stroke component and a drilling component disposed on the stroke component. The drilling component has a drill bit. During drilling, the stroke component can drive the drill bit of the drilling component to move and contact the frame, and the drilling component can drive the drill bit to drill a hole in the frame.

[0009] Preferably, the workbench includes a support plate fixed on the frame and a positioning frame fixed on the upper part of the support plate. The side wall contour of the positioning frame is the same as the lower inner wall contour of the seat frame, and the seat frame is adapted to be installed on the outside of the positioning frame.

[0010] Preferably, the seat frame fixing mechanism includes multiple sets of pressing components circumferentially fixed to the support plate. The pressing components include a lifting cylinder vertically fixed to the support plate and a connecting block horizontally arranged on the output end of the lifting cylinder. The outer end of the connecting block is provided with a connecting shaft, and the lower end of the connecting shaft is fixed with a pressure block. The lifting cylinder can drive the connecting block to move downward so that the pressure block presses against the upper end of the seat frame.

[0011] Preferably, there are four sets of clamping components, which are regularly arranged circumferentially on the outside of the seat frame.

[0012] Preferably, the pressing block is a rubber block.

[0013] Preferably, the operating table surface has multiple fan-shaped connecting through holes on the outer side of the workbench, and multiple fan-shaped pushing cylinders are provided on the bottom surface of the operating table surface corresponding to the connecting through holes. The stroke component includes the pushing cylinders and a mounting plate disposed on the output end of the pushing cylinders. The upper end of the mounting plate extends out of the connecting through holes and is fixedly connected to a base. The drilling component includes a drive motor fixed on the base, a connector mounted on the drive motor, and a drill bit disposed on the connector. During drilling, the pushing cylinder drives the mounting plate to move within the connecting through holes and moves the drilling component closer to the seat frame and makes the drill bit contact the seat frame. The drive motor drives the drill bit to drill holes in the seat frame.

[0014] Preferably, two drilling components are arranged side by side on the rear side of the workbench, and a push cylinder is provided below the two drilling components. A square long plate is fixed on the mounting plate on the output end of the push cylinder, and the drive motor of the drilling component is fixed to the square long plate through a connecting plate.

[0015] Preferably, guide rails are fixedly provided on both sides of the connecting through hole, and sliders that cooperate with the guide rails are fixedly provided on both sides of the bottom of the base or square plate.

[0016] Preferably, the system also includes a worktable lifting mechanism, which includes a motor, a reducer, a coupling, a drive shaft, and a screw. The motor shaft is connected to the drive shaft via the coupling, and the upper end of the screw is connected to the bottom of the support plate via a fixing block. The motor can drive the drive shaft to rotate, thereby rotating the screw to achieve the lifting and lowering of the support plate.

[0017] This utility model adopts the above-mentioned technical solution. Through the positioning frame, the operator can quickly position the seat frame onto the worktable without manual handling, saving effort. Then, by moving the connecting block above the seat frame, the lifting cylinder drives the connecting block downwards to the pressure block, locking the seat frame onto the worktable. When the drilling device drills holes in the seat frame, the frame will not shake, ensuring high drilling accuracy. The drilling component uses a drive motor to drive the drill bit, and its movement is driven by a stroke component, which is a push cylinder. Furthermore, the drilling component has guide rails and sliders on both sides, ensuring smooth operation and high drilling accuracy. Multiple drilling devices are arranged in a fan shape around the worktable, allowing for simultaneous drilling of multiple holes on the seat frame or individual drilling as needed, which is very convenient and efficient. In addition, when the seat frame requires a waist-shaped hole, the motor-driven screw can rotate, moving the entire worktable and seat frame up and down together. This allows the drill bit of the drilling component to drill holes longer than circular holes, such as waist-shaped holes, which is very convenient and has a wide range of applications.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] like Figures 1-9 The illustrated seat frame drilling machine includes a frame 1, a worktable 2 mounted on the frame 1, a seat frame fixing mechanism, and a seat frame drilling mechanism, wherein...

[0033] Workbench 2 is set on the operating table surface 100 of frame 1, and is suitable for positioning and supporting seat frame 200;

[0034] A seat frame fixing mechanism is provided on the worktable 2 and located outside the seat frame 200, which is suitable for locking the seat frame 200 on the worktable 2;

[0035] The frame drilling mechanism includes multiple drilling devices disposed on the outside of multiple sets of worktables 2. Each drilling device includes a stroke component and a drilling component disposed on the stroke component. The drilling component has a drill bit 15. When drilling, the stroke component can drive the drill bit 15 of the drilling component to contact the frame 200, and the drilling component can drive the drill bit 15 to drill a hole in the frame 200.

[0036] In the above technical solution, the drilling machine includes a worktable, a frame fixing mechanism, and a frame drilling mechanism; the worktable can support and position the frame, and the frame fixing mechanism can lock the frame on the worktable so that the frame will not shake and the drilling accuracy is high; multiple drilling devices are arranged in a fan shape around the worktable, which can drill multiple holes on the frame at the same time or drill holes individually as needed, which is very convenient and has high drilling efficiency.

[0037] Furthermore, the workbench 2 includes a support plate 3 fixed to the frame 1 and a positioning frame 4 fixed to the upper end of the support plate 3. The side wall contour of the positioning frame 4 is the same as the lower inner wall contour of the seat frame 200, and the seat frame 200 is adapted to be fitted outside the positioning frame 4. In this technical solution, the lower part of the seat frame can be fitted outside the positioning frame, and the positioning frame plays a positioning role for the seat frame, which can prevent the device from circumferentially shaking and can realize the rapid positioning of the seat frame.

[0038] Furthermore, the seat frame fixing mechanism includes multiple sets of clamping components circumferentially fixed to the support plate 3. Each clamping component includes a lifting cylinder 5 vertically fixed to the support plate 3 and a connecting block 6 horizontally disposed on the output end of the lifting cylinder 5. A connecting shaft 7 passes through the outer end of the connecting block 6, and a pressure block 8 is fixedly disposed at the lower end of the connecting shaft 7. The lifting cylinder 5 can drive the connecting block 6 to move downwards, causing the pressure block 8 to press against the upper end of the seat frame 200. In this technical solution, when locking the seat frame, the lifting cylinder rotates the connecting block to the top of the seat frame and moves it downwards to the pressure block to press against the seat frame. The seat frame is tightly locked on the worktable, effectively preventing seat frame wobbling and making drilling more precise. It should be noted that the connecting block is manually operated, which is very convenient.

[0039] Furthermore, there are four sets of clamping components, arranged circumferentially on the outer side of the seat frame 200. In this technical solution, the four sets of clamping components clamp the seat frame from the four corners, which can make the seat frame firmly locked on the worktable and improve the drilling accuracy.

[0040] Furthermore, the pressure block 8 is a rubber block. In this technical solution, using a rubber block as the pressure block can reduce contact wear between the pressure block and the seat frame, thus better protecting the seat frame.

[0041] Furthermore, the operating table 100 has multiple fan-shaped connecting through holes 9 on the outer side of the workbench 2. The bottom surface of the operating table 100 has multiple fan-shaped pushing cylinders 10 corresponding to the connecting through holes 9. The stroke component includes the pushing cylinder 10 and a mounting plate 11 disposed on the output end of the pushing cylinder 10. The upper end of the mounting plate 11 extends out of the connecting through hole 9 and is fixedly connected to a base 12. The drilling component includes a drive motor 13 fixed on the base 12, a connector 14 mounted on the drive motor 13, and a drill bit 15 disposed on the connector 14. When drilling, the pushing cylinder 10 drives the mounting plate 11 to move within the connecting through hole 9 and moves the drilling component closer to the seat frame 200 and makes the drill bit 15 contact the seat frame 200. The drive motor 13 drives the drill bit 15 to drill a hole in the seat frame 200. In this technical solution, the drilling component uses a drive motor to power the drill bit, and its movement is driven by a stroke component, which is a push cylinder. This ensures smooth operation and high drilling accuracy. Multiple drilling devices are arranged in a fan shape around the worktable, allowing for simultaneous drilling of multiple holes on the frame or individual drilling as needed, which is very convenient and efficient. The connecting through hole represents the stroke distance of the drilling device. The push cylinder on the back of the worktable drives the mounting plate to move within the connecting through hole, thereby moving the base and drilling component on the mounting plate, facilitating drilling on the frame.

[0042] Furthermore, two drilling components are arranged side-by-side on the rear side of the workbench 2, and a push cylinder 10 is located below the two drilling components. A square elongated plate 16 is fixed on the mounting plate 11 on the output end of the push cylinder 10, and the drive motor 13 of the drilling components is fixed to the square elongated plate 16 through a connecting plate 17. In this technical solution, the two drilling components arranged side-by-side and the push cylinder are installed together, which can reduce costs.

[0043] Furthermore, guide rails 18 are fixedly provided on both sides of the connecting through hole 9, and sliders 19 that cooperate with the guide rails 18 are fixedly provided on both sides of the bottom of the base 12 or the square elongated plate 16. In this technical solution, the cooperation between the guide rails and the sliders makes the drilling component move more smoothly and the drilling accuracy is higher.

[0044] like Figure 8 and 9As shown, the drilling machine also includes a worktable lifting mechanism, which includes a motor 20, a reducer 21, a coupling 22, a drive shaft 23, and a screw 24. The motor shaft of the motor 20 is connected to the drive shaft 23 via the coupling 22. The upper end of the screw 24 is connected to the bottom of the support plate 3 via a fixing block 25. The motor 20 can drive the drive shaft 23 to rotate, thereby rotating the screw 24 to achieve the lifting and lowering of the support plate 3. In this technical solution, when the mounting of the seat frame requires an oblong hole, the entire worktable and seat frame can be moved up and down together by rotating the screw driven by the motor, allowing the drill bit of the drilling component to drill a hole on the seat frame that is longer than a circular hole. Figure 8 The hole shapes shown, such as the waist-shaped hole 300, are very convenient and have a wide range of applications.
