Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing technology, specifically to a CNC multi-end automatic cutting and tenoning device. Background Technology

[0002] In industries such as furniture manufacturing and door and window processing, tenoning machines are core equipment for achieving precise connections between wooden components. Traditional models suffer from significant technical bottlenecks. Existing equipment often employs a single-station processing mode, requiring multiple manual adjustments to the board positioning to complete cutting, drilling, and other processes, resulting in low production efficiency and large accumulated errors. Particularly problematic is the need to manually change clamping components when switching between different tenon types. This is not only cumbersome but also prone to mechanical interference between the cutting saw blade and clamping components due to clamping position deviations, posing safety hazards. The new CNC multi-end automatic cutting tenoning device, through an integrated multi-axis linkage control system, can complete multiple processes simultaneously in a single clamping operation. Its automatic clamping mechanism employs an intelligent avoidance algorithm, using laser ranging to monitor the spatial position of the saw blade and clamps in real time, ensuring a dynamic safety distance. This equipment can process not only traditional straight tenons and dovetail tenons but also achieve digital forming of complex curved surface tenons and mortises. It is widely used in custom furniture production lines and the restoration of ancient building wooden components, effectively solving the industry pain point of balancing efficiency and precision in traditional processes.

[0003] In the existing technology, existing devices can only perform cutting or drilling, and can only be operated independently. Multiple processes are processed in sequence, which requires the plate to be positioned and installed multiple times. Furthermore, when tenoning, the operator needs to manually change the clamping components to prevent interference between the cutting saw blade and the clamping components. Therefore, this device provides a CNC multi-end automatic cutting and tenoning device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a CNC multi-end automatic cutting and tenoning device to solve the aforementioned technical problems.

[0005] The present invention adopts the following technical solution: a CNC multi-end automatic cutting and tenoning device, comprising a frame body, with movable slide rails fixedly installed on the front and rear sides of the top of the frame body, a processing frame slidably installed on the outer side of the movable slide rails, and multiple plate positioning and clamping components fixedly installed on the top of the frame body;

[0006] A first drive motor is fixedly installed on the top of the processing frame. A transmission screw is fixedly installed on the output end of the first drive motor. A sliding frame is installed on the outer thread of the transmission screw. Two auxiliary electric telescopic rods are fixedly installed on the top of the processing frame. The sliding frame is fixedly installed on the output end of the auxiliary electric telescopic rods.

[0007] A second drive motor is fixedly installed on one side of the sliding frame, and a drive shaft is fixedly installed on the output end of the second drive motor. A rotating frame is fixedly installed on the outside of the drive shaft. Multiple drive frames are fixedly installed on multiple sides of the rotating frame. A drilling component, a grinding component, and a cutting component are arranged above the drive frame.

[0008] Preferably, a support chain is provided above the processing frame, two guide rails are fixedly installed on one side of the processing frame, multiple sliders are slidably installed on the outer side of the guide rails, a brake motor is fixedly installed on the top of the processing frame, and a mounting base is fixedly installed on one side of the slider.

[0010] Preferably, a pulley is fixedly installed above the output shaft of the third drive motor, a pulley is fixedly installed on the outer side of the rotating shaft, and a synchronous belt is tensioned on the outer side of the pulley.

[0011] Preferably, the plate positioning and clamping component includes an electric telescopic rod and a clamping block. Multiple electric telescopic rods are fixedly installed above the plate positioning and clamping component, and the clamping block is fixedly installed at the output end of the electric telescopic rod.

[0012] Preferably, a power supply box and a control panel are fixedly connected to one side of the main frame body.

[0013] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0014] 1. The transmission screw can drive the sliding frame to descend through threaded engagement. The auxiliary electric telescopic rod can provide auxiliary support for the lifting and lowering of the sliding frame. Multiple drilling, grinding and cutting components are set above the rotating frame, allowing the device to process multiple plates at multiple workstations. After drilling and cutting are completed, the second drive motor can drive the drive shaft and rotating frame to rotate, which can cause the rotating frame to rotate the drive frame and grinding components, and then lower the rotating frame again, so that the grinding components can grind the plate. This device does not require the operator to move the plate position multiple times, which can improve work efficiency.

[0015] 2. When the board needs to be tenoned, the slider can be controlled to slide above the guide rail, allowing the saw blade to descend and the third drive motor to start. After the third drive motor starts, it can drive the rotating shaft and saw blade to rotate through the pulley and synchronous belt. After the saw blade rotates, the board positioning and clamping component can slide above the moving slide rail, allowing the saw blade to perform tenoning on the clamped board. This makes the device highly efficient, eliminating the need for multiple positioning and movement of the board, and enabling integrated processing. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0027] This utility model embodiment provides a CNC multi-end automatic cutting and tenoning device, including a frame body 1, with movable slide rails 2 fixedly installed on the front and rear sides of the top of the frame body 1, a processing frame 4 slidably installed on the outer side of the movable slide rails 2, and multiple plate positioning and clamping components 3 fixedly installed on the top of the frame body 1.

[0028] A first drive motor 5 is fixedly installed on the top of the processing frame 4. A transmission screw 6 is fixedly installed on the output end of the first drive motor 5. A sliding frame 7 is installed on the outer thread of the transmission screw 6. Two auxiliary electric telescopic rods 8 are fixedly installed on the top of the processing frame 4. The sliding frame 7 is fixedly installed on the output end of the auxiliary electric telescopic rods 8.

[0029] A second drive motor 9 is fixedly installed on one side of the sliding frame 7. A drive shaft 10 is fixedly installed at the output end of the second drive motor 9. A rotating frame 11 is fixedly installed on the outside of the drive shaft 10. Multiple drive frames 12 are fixedly installed on multiple sides of the rotating frame 11. A drilling component 13, a grinding component 14, and a cutting component 15 are arranged above the drive frame 12.

[0030] Furthermore, multiple drilling components 13, grinding components 14, and cutting components 15 are arranged above the rotating frame 11, allowing the device to process multiple plates at multiple workstations. After drilling and cutting are completed, the second drive motor 9 drives the drive shaft 10 and the rotating frame 11 to rotate, which in turn drives the drive frame 12 and the grinding components 14 to flip. The rotating frame 11 then descends again, allowing the grinding components 14 to grind the plates. This eliminates the need for operators to move the plates multiple times, thus improving work efficiency.

[0031] In a further preferred embodiment of the present invention, a support chain 16 is provided above the processing frame 4, two guide rails 17 are fixedly installed on one side of the processing frame 4, a plurality of sliders 18 are slidably installed on the outer side of the guide rails 17, a brake motor 19 is fixedly installed on the top of the processing frame 4, and a mounting base 20 is fixedly installed on one side of the slider 18.

[0032] Furthermore, the brake motor 19 allows the slider 18 to stop at any position after sliding, enabling the saw blade 24 to cut grooves of different depths.

[0033] In a further preferred embodiment of the present invention, two third drive motors 21 are fixedly installed on one side of the mounting base 20, two bases 22 are fixedly installed on the bottom of the mounting base 20, a rotating shaft 23 is rotatably installed on the inner side of the base 22, and two saw blades 24 are fixedly installed on the outer side of the rotating shaft 23.

[0034] Furthermore, when the board needs to be tenoned, the slider 18 can be controlled to slide above the guide rail 17, allowing the saw blade 24 to descend and the third drive motor 21 to start. After the third drive motor 21 starts, it can drive the rotating shaft 23 and the saw blade 24 to rotate through the pulley 25 and the synchronous belt 26. After the saw blade 24 rotates, the board positioning clamping component 3 can slide above the moving guide rail 2, allowing the saw blade 24 to perform tenoning on the clamped board.

[0035] In a further preferred embodiment of the present invention, a pulley 25 is fixedly installed above the output shaft of the third drive motor 21, a pulley 25 is fixedly installed on the outer side of the rotating shaft 23, and a synchronous belt 26 is tensioned on the outer side of the pulley 25.

[0036] Furthermore, the synchronous belt 26 and pulley 25 allow the third drive motor 21 to drive multiple saw blades 24 to rotate, enabling the saw blades 24 at both ends of the rotating shaft 23 to simultaneously process the tenons on both sides of the plate.

[0037] In a further preferred embodiment of the present invention, the plate positioning and clamping component 3 includes an electric telescopic rod and a clamping block. Multiple electric telescopic rods are fixedly installed on the top of the plate positioning and clamping component 3, and the clamping block is fixedly installed on the output end of the electric telescopic rod.

[0038] Furthermore, the electric telescopic rod can drive the clamping block to move, and the moved clamping block can clamp the two sides of the plate, so that the drilling part 13, grinding part 14, cutting part 15 and saw blade 24 will not interfere with each other when processing the plate.

[0039] In a further preferred embodiment of this utility model, a power supply box and a control panel are fixedly connected to one side of the frame body 1.

[0040] Furthermore, the power supply box can supply power to multiple drive components of the device, and the control panel can set the cutting parameters, allowing operators to perform the machining without manual operation, which would otherwise be time-consuming and labor-intensive.

[0041] The specific operation involves placing the sheet material to be processed above the sheet material positioning and clamping component 3 for clamping and fixing. The processing frame 4 is then moved above the sliding rail 2. The first drive motor 5 is then controlled to rotate the transmission screw 6. The transmission screw 6, through threaded engagement, drives the sliding frame 7 to descend. An auxiliary electric telescopic rod 8 provides support for the lifting and lowering of the sliding frame 7. Multiple drilling components 13, grinding components 14, and cutting components 15 are arranged above the rotating frame 11, allowing the device to process multiple sheets at multiple workstations. After drilling and cutting, the second drive motor 9 drives the drive shaft 10 and the rotating frame 11 to rotate, allowing the rotating frame 11 to drive the drive frame 12 and grinding components 14. The machine is flipped over and the rotating frame 11 is lowered again, allowing the grinding component 14 to grind the board. This eliminates the need for operators to move the board multiple times, improving work efficiency. When the board needs to be tenoned, the slider 18 can be controlled to slide above the guide rail 17, allowing the saw blade 24 to descend and the third drive motor 21 to start. After the third drive motor 21 starts, it drives the rotating shaft 23 and the saw blade 24 to rotate via the pulley 25 and the synchronous belt 26. After the saw blade 24 rotates, the board positioning and clamping component 3 can slide above the moving slide rail 2, allowing the saw blade 24 to perform tenoning on the clamped board. This makes the device highly efficient, eliminating the need for multiple positioning and movement of the board, and enabling integrated processing.

[0042] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
