[0041] Embodiment 1:

[0042] Please refer to Figures 1-7 The embodiment of the present application discloses a multi-layer plywood cutting tool for enclosure system, which comprises a machine tool cover and a workbench 1, a side pressing mechanism, a plurality of top pressing mechanisms 4 and a cutting mechanism 5 installed in the machine tool cover. A storage opening is formed at the top of the machine tool cover, and a transparent protective door can be installed in the storage opening to facilitate observation of the internal processing condition.

[0043] The workbench 1 is fixed to the inner bottom wall of the machine tool cover, and has a first side end 11 and a second side end 12 arranged oppositely, and a square plywood 8 to be processed is placed on the workbench 1. In some embodiments, the workbench can be a lifting workbench.

[0044] The side-pressing mechanism includes a first clamping mechanism and a second clamping mechanism. The first clamping mechanism and the second clamping mechanism have the same structure, both including a fixed clamping plate 2 and a movable clamping plate 3. In the first clamping mechanism, the fixed clamping plate 2 and the movable clamping plate 3 are arranged on both sides of the worktable 1 along the direction of the first side end 11 and the second side end 12, and the movable clamping plate 3 slides along the direction of the first side end 11 and the second side end 12 to cooperate with the fixed clamping plate 2 in clamping the plywood 8. In the second clamping mechanism, the fixed clamping plate 2 and the movable clamping plate 3 are arranged on both sides of the worktable 1 along the direction perpendicular to the first side end 11 and the second side end 12, and the movable clamping plate 3 slides along the direction perpendicular to the first side end 11 and the second side end 12 to cooperate with the fixed clamping plate 2 in clamping the plywood 8. The first clamping mechanism and the second clamping mechanism can horizontally limit the plywood 8 from multiple directions.

[0045] Multiple pressing mechanisms 4 are arranged circumferentially and installed on the outer periphery of the workbench 1. The output end of each pressing mechanism 4 can move up and down along the height direction of the workbench 1 and press on the upper surface of the plywood 8, thus limiting the plywood 8 in the vertical direction.

[0046] The cutting mechanism includes a first cutting tool assembly 5 and a second cutting tool assembly 6 arranged on both sides of the worktable 1 along the direction of the first side end 11 and the second side end 12. The cutting ends of the first cutting tool assembly 5 and the second cutting tool assembly 6 rotate towards the worktable 1 to cut the plywood 8 to process positioning slots 81. In this embodiment, there are four positioning slots 81 to be processed. The first cutting tool assembly 5 and the second cutting tool assembly 6 each have two slots, which are arranged corresponding to the four corners of the plywood 8, so that four positioning slots can be processed at one time without adjusting the orientation of the plywood midway, thus avoiding affecting the processing accuracy.

[0047] Specifically, both the first cutting tool assembly 5 and the second cutting tool assembly 6 include a tool holder 51, a drive motor 52, a gripper 53, and a cutting head 54. The tool holder 51 is slidably mounted inside the machine tool cover next to the worktable 1 via a three-axis sliding mechanism; the drive motor 52 is fixed on the tool holder 51; the gripper 53 is mounted on the output shaft of the drive motor 52, and the gripper 53 can be a pneumatic chuck; the mounting end of the cutting head 54 is clamped on the gripper 53, and the cutting end can cut plywood 8.

[0048] Plywood chips contain adhesive substances, which are more likely to adhere to the machined surface or the cutting tool, affecting the machining quality and easily accelerating the wear of the cutting tool. Therefore, this embodiment also includes a chip collection assembly 7, which includes a collection cover 71 and a negative pressure suction mechanism 72. The collection cover 71 is mounted on the tool holder 51 and its collection end is arranged corresponding to the cutting tool 54. The suction end of the negative pressure suction mechanism 72 is connected to the inner cavity of the collection cover 71, which can prevent chips from flying around during cutting and collect them for subsequent processing. When the negative pressure suction mechanism 72 sucks up chips, it can accelerate the airflow near the cutting tool 54, which can cool down the chip, remove the heat from the cutting tool 54 and the plywood 8, reduce the wear of the cutting tool 54, avoid thermal stress concentration in the plywood 8, and improve the machining quality of the plywood 8.

[0049] Specifically, the cutting head 54 includes a cutting body 541 and cutting blades 542. The mounting end of the cutting body 541 can be clamped onto the gripper 53. Multiple cutting blades 542 are circumferentially and evenly spaced on the outer peripheral sidewall of the cutting body 541, and each cutting blade 542 has an angle α with the tangent of the outer circumferential surface of the cutting body 541, with the angle α being 58.8°. The cutting blades 542 are made of diamond material, which is hard, not easy to wear, reduces the replacement frequency, and improves processing efficiency.

[0050] Specifically, the blade 542 and the blade body 541 are fixed by welding. Since the plywood 8 to be processed is multiple stacked and processed at the same time, its thickness and hardness are higher. Compared with the blade head 54 which uses replaceable blades 542 connected by screws, the blade body 541 and the blade 542 are less prone to misalignment due to the integral welding, which helps to improve processing accuracy and ensure processing quality.

[0051] Specifically, a linear sliding mechanism for the clamping plate 3 is also provided, which drives the movable clamping plate 3 to slide horizontally. The movable clamping plate 3 is installed at the output end of the linear sliding mechanism. In specific implementations, the linear sliding mechanism can be a linear sliding mechanism with any of the following driving forms: pneumatic, electric, or hydraulic.

[0052] The fixed clamping plate 2 and the movable clamping plate 3 have the same structure, both including a support plate 21 and a side push plate 22. The support plate 21 is arranged horizontally to support the bottom of the plywood 8 and works in conjunction with the pressure plate 42 to prevent the edges of the plywood 8 from bending downward or warping during processing, which would affect the processing quality. The side push plate 22 is fixed on the side of the support plate 21 away from the worktable 1 so as to abut against the side wall of the plywood 8.

[0053] Specifically, the pressing mechanism 4 includes a lifting drive mechanism 41 and a pressure plate 42. The lifting drive mechanism 41 is installed on the outer periphery of the worktable 1. One end of the pressure plate 42 is rotatably mounted on the lifting end of the lifting drive mechanism 41 and fixed by a locking bolt 43, while the other end can press against the surface of the plywood 8. The lifting drive mechanism 41 can also be a linear lifting mechanism with any of the following drive forms: pneumatic, electric, or hydraulic. When the plywood 8 is placed or removed, the pressure plate 42 can be rotated outward. When the plywood 8 is in place, the pressing end of the pressure plate 42 is rotated inward to above the plywood 8, and the lifting mechanism is activated to press the plywood 8 firmly.

[0054] In some other embodiments, a pressure plate horizontal sliding mechanism may also be provided. The lifting drive mechanism 41 is installed at the output end of the pressure plate horizontal sliding mechanism. The pressure plate 42 is driven to move closer to or further away from the plywood 8 through the pressure plate horizontal sliding mechanism to accommodate plywood 8 of different sizes.

[0055] Specifically, a pressure plate height compensation mechanism 44 is also provided. The upper end of the pressure plate height compensation mechanism 44 can be slidably installed on the side of the pressure plate 42 away from the lifting mechanism along the height direction and can be locked by a limiting mechanism. The lower end face can abut against the upper surface of the plywood 8. For example, the pressure plate height compensation mechanism 44 can be a screw, which is threaded to the pressure plate 42. The head of the screw abuts against the plywood 8, and the distance between its head and the pressure plate 42 can be adjusted by turning the screw.

[0056] Specifically, a controller is also provided, which is electrically connected to various electronic components such as drive motor 52, gripper 53, clamping plate linear sliding mechanism, lifting drive mechanism 41, pressure plate horizontal sliding mechanism, and negative pressure suction mechanism 72.
