[0020] A method for processing wooden furniture using a combination lathe, applied to the aforementioned processing lathe, the method comprising the following steps: S1. Preparations; Equipment inspection and initialization: Check whether all parts of the lathe are working properly, and move the mounting and transfer components to their initial safe positions; Material preparation: Insert the different types of bolts to be assembled into the corresponding bolt boxes, and ensure that the pressure plate can push the bolt body towards the discharge hole under the action of the first spring. Place the furniture components to be assembled neatly on the support rod of the storage bracket.

[0021] S2: Gripping and positioning of furniture components; Activate the second cylinder of the transfer component to adjust the height of the gripping mechanism; Start the fourth and fifth motors and adjust the angle of the gripping mechanism so that it faces the furniture component to be gripped. Activate the fifth electric telescopic rod to align the support plate with the first clamping plate, then activate the third cylinder to adjust the horizontal position of the gripping mechanism so that the first and second clamping plates are above the furniture component to be gripped, with the second clamping plate located between the processing platform and the support rod, and the support plate located below the furniture component to be gripped. The fifth cylinder is activated to control the support plate to lift the furniture component so that it is above the second clamping plate. The fifth cylinder is activated to control the support plate to lift the corresponding furniture component. When the clamping component is higher than the second clamping plate, the fourth electric telescopic rod is activated to control the second clamping plate to move to correspond with the first clamping plate. The fourth cylinder is activated to control the second clamping plate to move upward, so that the first clamping plate and the second clamping plate clamp the furniture component. Then the fifth cylinder is retracted to control the support plate to move downward to below the corresponding support rod, so as to realize the gripping operation of the gripping mechanism. After the gripper is firmly secured, the third cylinder retracts to control the gripping mechanism to move off the storage bracket. Through the coordinated action of the second cylinder, the fourth motor, the fifth motor, and the third cylinder, the furniture component is smoothly transferred to the predetermined processing position above the processing platform.

[0022] S3: Support and fixation of furniture components; Adjusting the support: Based on the placement and height of the furniture components on the processing platform, the hydraulic cylinder is activated to raise or lower the processing platform via the output shaft, thereby adjusting the protrusion height of the two support plates in the slotted holes and providing stable bottom support for the furniture components.

[0023] S4: Install components to secure furniture parts; S41: Installation preparation; Activate the second electric telescopic rod to align the locking head with the slot of the drive head on the target bolt box, activate the sixth electric telescopic rod to control the linear movement of the drive head so that it can smoothly engage with the slot of the drive head, and the screwdriver can smoothly engage with the target bolt body. The first slider of the operating installation component moves up and down along the first guide rail to adjust the overall height. The second slider moves horizontally along the second guide rail. The first electric telescopic rod extends and retracts to adjust the horizontal position. The first mounting bracket and subsequent components are rotated by the first motor. The second mounting bracket and subsequent components are rotated by the second motor, so that the discharge hole on the bolt box to be used is positioned at the position where the furniture component needs to be bolted.

[0024] S42: Screw in the bolt: The third motor control card engages and drives the drive head to rotate, thereby rotating the screwdriver. With the help of a rotating screwdriver, the bolt is screwed into the hole in the furniture component; As the bolt is screwed in, the sliding bracket will overcome the elastic force of the second spring and retract along the guide rod towards the block, ensuring that the screwdriver is always in effective contact with the bolt head and provides continuous torque until the bolt is tightened to the correct position.

[0025] S43: Replace bolt type / location: After one bolt is tightened, the third motor stops reversing. The entire assembly is retracted, the locking head separates from the drive head, and the screwdriver is removed from the tightened bolts; By controlling the actions of the first slider, the second slider, the first electric telescopic rod, the first motor, the second motor, and the first cylinder, the installation assembly is moved to the next position where a bolt needs to be tightened. If the bolt type needs to be changed, the second electric telescopic rod is extended or retracted to move another bolt box containing the required bolt type to the working position, and the drive head of the bolt box aligns with the engaging head. S41 and S42 are then repeated.

[0026] S5: Complete processing and unloading; Inspection: Check that all pre-installed bolts have been tightened as required; Release component: The gripping mechanism of the transfer assembly releases its grip on the furniture component; Remove finished products: The assembled furniture parts or products are picked up from the processing platform and transferred to the finished product storage area or the next workstation using the transfer components; Reset: Each moving part returns to its initial position, preparing for the next processing operation.

The machining lathe of this invention integrates transfer components, support components and multi-degree-of-freedom installation components to realize the fully automated operation of furniture components from gripping, positioning, support to bolt fastening, which significantly reduces manual intervention and improves production efficiency and consistency.

[0028] 2. The machining lathe of this invention adopts a modular bolt box design. Each bolt box can pre-store a specific type of bolt and can be quickly switched through a second electric telescopic rod. Combined with the precise docking of the locking head and the drive head, it realizes the automatic selection and tightening of bolts of different specifications, meeting the diverse connection needs of complex furniture.

[0029] 3. The mounting components in the machining lathe of this invention have six degrees of freedom of adjustment (lifting, horizontal movement, rotation and pitch adjustment). Combined with the electrically controlled guide rail and servo motor, it can accurately position the bolt fastening position and adapt to the geometry and connection angle of different furniture components.

[0030] 4. The support assembly in the machining lathe of the present invention adjusts the height of the support plate through a hydraulic cylinder to provide a stable base for the furniture components; the spring pressure plate in the bolt box continuously pushes the bolt to the discharge hole to ensure reliable material supply; the design of the sliding bracket and the second spring ensures that the screwdriver is always in close contact with the bolt head, ensuring stable torque transmission during the tightening process.

[0031] 5. The transfer component in the machining lathe of the present invention is controlled by multiple cylinders, motors and telescopic rods to realize the gripping, lifting, clamping and spatial positioning adjustment of furniture components, avoiding the risks of manual handling, and the design of the support plate and clamping plate ensures that the components do not slip or get damaged during the transfer process.

[0032] 6. The machining lathe of this invention reduces reliance on skilled workers through fully automated operation. Operators only need to complete material preparation and monitoring, which greatly reduces labor intensity and training costs, while also reducing quality problems caused by human error.

[0033] 7. The machining lathe of this invention can quickly adapt to the assembly needs of different furniture products. The machining parameters and bolt types can be adjusted through program control, supporting small-batch, multi-variety production mode, improving equipment utilization and production line flexibility.
