[0019] like Figures 1-6 As shown in the figure, a woodworking transverse V-grooving machine provided in this application embodiment includes a frame 1, a workbench 2, and a PLC controller, wherein:

[0020] The frame 1 has at least two parallel crossbeams 3 along the Y-axis direction. Each crossbeam 3 has a Y-axis slide block 4 slidably mounted on it. A Y-axis drive device 5 is also provided for driving the Y-axis slide block 4 to move back and forth along the Y-axis direction, and a first position sensor is provided for measuring the position change of the Y-axis slide block 4. A first Z-axis slide block 6 is slidably mounted on one side of the Y-axis slide block 4. A first Z-axis drive device 7 is also provided for driving the first Z-axis slide block 6 to move up and down along the Z-axis direction, and a second position sensor is provided for measuring the position change of the first Z-axis slide block 6. A second Z-axis slide block is slidably mounted on the other side of the Y-axis slide block 4. 8. It is also provided with a second Z-axis drive device 9 for driving the second Z-axis slide 8 to move up and down along the Z-axis direction, and a third position sensor for measuring the position change of the second Z-axis slide 8. The first Z-axis slide 6 and the second Z-axis slide 8 are respectively provided with a first saw blade device 10 and a second saw blade device 20. The first saw blade device 10 and the second saw blade device 20 both include a sawing motor 30 and a saw blade 40 installed on the output shaft of the sawing motor 30. A V-shaped angle is formed between the first saw blade device 10 and the saw blade 40 of the second saw blade device 20. A speed sensor is provided on the sawing motor 30.

[0021] The worktable 2 is slidably mounted on the frame 1 and located below the crossbeam 3. An X-axis drive device 50 is provided between the worktable 2 and the frame 1 to drive the worktable 2 to move left and right along the X-axis direction.

[0022] The PLC controller is electrically connected to the Y-axis drive unit 5, the first Z-axis drive unit 7, the second Z-axis drive unit 9, the sawing motor 30, the first position sensor, the second position sensor, the third position sensor, and the speed sensor. The first, second, and third position sensors can be, but are not limited to, linear encoders, and the speed sensor can be, but is not limited to, a Hall effect speed sensor. The PLC controller program adopts a modular design, including an initialization module, a parameter setting module, a motion control module, and a safety monitoring module. Users can input processing parameters (such as sawing depth and speed) through the human-machine interface (HMI) on the machine tool, i.e., a button panel or a touch screen panel. The PLC controller automatically adjusts the movement trajectory and speed of the saw blade 40 based on these parameters. The PLC controller has comprehensive safety protection functions, such as overload protection, limit protection, and emergency stop. When an abnormal situation occurs, the PLC controller will immediately stop the movement of the saw blade 40 and display fault information through the HMI to ensure the safety of operators and equipment. The PLC controller can realize automated processing, such as automatic feeding, automatic positioning, and automatic sawing, improving production efficiency and processing quality.

[0023] In operation, this invention uses saw blades 40 of the first saw blade device 10 and the second saw blade device 20, which are arranged in a V-shape, to process the wood. The blades rotate, and the X-axis drive device 50 drives the worktable 2, causing the wood on the worktable 2 to move left and right along the X-axis, thus cutting a transverse V-shaped groove on the wood surface. The Y-axis drive device 5 drives the Y-axis slide 4 to move back and forth along the Y-axis, the first Z-axis drive device 7 drives the first Z-axis slide 6 to move up and down along the Z-axis, and the second Z-axis drive device 9 drives the second Z-axis slide 8 to move up and down along the Z-axis. This allows adjustment of the front-back and vertical positions of the first saw blade device 10 and the second saw blade device 20, enabling the saw blades 40 to... The saw blade 40 is cut at different angles and depths. A first position sensor, a second position sensor, and a third position sensor measure the position changes of the Y-axis slide 4, the first Z-axis slide 6, and the second Z-axis slide 8, respectively. A speed sensor measures the rotational speed of the sawing motor 30. The PLC controller, as the core control unit, receives signals from each sensor, performs logical operations and data processing according to a preset program, and then outputs control signals to the Y-axis drive device 5, the first Z-axis drive device 7, the second Z-axis drive device 9, and the sawing motor 30. This enables precise control of the saw blade 40's forward and backward movement, up and down movement, and rotational speed, ensuring sawing accuracy and stability.

[0024] Specifically, angle adjustment components 60 are provided between the first saw blade device 10 and the first Z-axis slide 6, and between the second saw blade device 20 and the second Z-axis slide 8. Each angle adjustment component 60 includes a mounting base 601, a rotating plate 602, a cam guide 603, and a gear shaft 604. The outer wall of the sawing motor 30 is fixedly connected to the mounting base 601, and the mounting base 601 is fixedly connected to the rotating plate 602. The first Z-axis slide 6 and the second Z-axis slide 8 are provided with multiple concentric arc holes 700. The stud of the cam guide 603 is threadedly connected to the rotating plate 602. The outer ring of the cam guide 603 contacts the side wall of the arc hole 700 and can rotate. The axle 604 includes a shaft portion 6041 and a gear portion 6042 disposed at one end of the shaft portion 6041. The shaft portion 6041 is rotatably mounted on the first Z-axis slide 6 or the second Z-axis slide 8. A top block 800 is sleeved on the protruding end of the shaft portion 6041. The top block 800 is fixedly connected to the first Z-axis slide 6 or the second Z-axis slide 8. An adjusting screw (not shown in the figure) for abutting against the outer wall of the shaft portion 6041 is threaded on the side wall of the top block 800. The gear portion 6042 is located on the side of the first Z-axis slide 6 or the second Z-axis slide 8 near the rotating plate 602. The upper edge of the rotating plate 602 is arc-shaped and has gear teeth 6021 that mesh with the gear portion 6042. When the adjusting screw is loosened, the gear shaft 604 can rotate freely. Since the upper edge gear teeth 6021 of the rotating plate 602 mesh with the gear part 6042 of the gear shaft 604, the angle of the rotating plate 602 can be adjusted by rotating it. The outer ring of the cam guide 603 can slide along the arc hole 700 and can rotate itself to adjust the tilt angle of the first saw blade device 10 or the second saw blade device 20. Tightening the adjusting screw can fix the gear shaft 604. At this time, the rotating plate 602 is in a fixed state.

[0025] Each crossbeam 3 has multiple first Y-axis rails 31 and multiple second Y-axis rails 32 installed on its two side walls along the Y-axis direction. The two sides of the Y-axis slide 4 are fixedly connected to the sliders on the first Y-axis rails 31 and the second Y-axis rails 32, respectively. The Y-axis drive device 5 includes a Y-axis motor and a Y-axis lead screw and nut assembly 51. The Y-axis motor and the Y-axis lead screw and nut assembly 51 are installed on the top of the crossbeam 3. The output shaft of the Y-axis motor (not shown in the figure) is connected to the lead screw of the Y-axis lead screw and nut assembly 51. The nut of the Y-axis lead screw and nut assembly 51 is fixedly connected to the Y-axis slide 4. In this embodiment, the Y-axis slide 4 includes a horizontal plate and vertical plates fixed at both ends of the horizontal plate. The nut of the Y-axis lead screw and nut assembly 51 is fixedly connected to the horizontal plate of the Y-axis slide 4. The Y-axis motor drives the Y-axis lead screw and nut assembly 51 to move. When the lead screw rotates, the nut moves along the lead screw axis, thereby driving the Y-axis slide 4 to move back and forth along the Y-axis direction.

[0026] Multiple first Z-axis linear guides 41 and multiple second Z-axis linear guides 42 are respectively installed on both sides of the Y-axis slide 4 along the Z-axis direction. The first Z-axis slide 6 and the second Z-axis slide 8 are fixedly connected to the sliders on the first Z-axis linear guides 41 and the second Z-axis linear guides 42, respectively. The first Z-axis drive device 7 and the second Z-axis drive device 9 are both cylinders. The Z-axis cylinder is installed on the Y-axis slide 4, and the piston rod of the Z-axis cylinder is fixedly connected to the first Z-axis slide 6 or the second Z-axis slide 8. The cylinder is used to drive the first Z-axis slide 6 or the second Z-axis slide 8 to move up and down along the Z-axis direction.

[0027] Furthermore, Z-axis anti-collision blocks 900 are detachably connected to both the first Z-axis slide 6 and the second Z-axis slide 8; adjusting blocks 1000 are detachably connected to both sides of the Y-axis slide 4, and the adjusting blocks 1000 are correspondingly located below the Z-axis anti-collision blocks 900. When the Z-axis anti-collision block 900 moves downward with the first Z-axis slide 6 or the second Z-axis slide 8, the height position of the adjusting block 1000 is set according to the height of the worktable 2 and the workpiece. The adjusting block 1000 can limit the Z-axis anti-collision block, thereby preventing the saw blades 40 of the first saw blade device 10 and the second saw blade device 20 from colliding with each other.

[0028] Multiple X-axis linear guides 11 are mounted on the frame 1 along the X-axis direction. The worktable 2 is fixedly connected to the sliders on the X-axis linear guides 11. The X-axis drive device 50 includes an X-axis geared motor 501, an X-axis helical rack 502, and a helical gear 503. The X-axis geared motor 501 is mounted on the bottom of the worktable 2. The X-axis helical rack 502 is mounted on the frame 1 along the X-axis direction. The helical gear 503 is mounted on the output shaft of the X-axis geared motor 501, and the helical gear 503 meshes with the helical rack. The X-axis geared motor 501 drives the helical gear 503 to rotate. While rotating, the helical gear 503 can move linearly along the helical rack, thereby driving the worktable 2 to move left and right along the X-axis direction.

[0029] The two ends of the crossbeam 3 are provided with columns 2000. The upper end of the column 2000 is fixedly connected to the end of the crossbeam 3, and the lower end is fixedly connected to the frame 1. The column 2000 and the crossbeam 3 form a gantry structure, which improves the structural stability.

[0030] A fixing plate 3000 is provided on the crossbeam 3 located at the front of the frame 1. The fixing plate 3000 is located at one end of the crossbeam 3. Multiple third Z-axis linear guides 30001 are installed on the fixing plate 3000 along the Z-axis direction. A third Z-axis slide block 4000 is fixedly connected to the slider of the third Z-axis linear guide 30001. The fixing plate 3000 is also provided with a third Z-axis drive device 5000 for driving the third Z-axis slide block 4000 to move up and down along the Z-axis direction. A third saw blade device 6000 is provided on the third Z-axis slide block 4000. Specifically, the third saw blade device 6000 has the same structure and working principle as the first saw blade device 10 and the second saw blade device 20. The third Z-axis drive device 5000 has the same structure and working principle as the first Z-axis drive device 7 and the second Z-axis drive device 9, which will not be described in detail here. The third saw blade device 6000 can be used to cut the edges of wood.

[0031] It should be understood that all the above embodiments are exemplary and not restrictive.
