[0032] A fully automatic cutting machine is a mechanical device used for sheet processing and is widely applied in industries such as furniture manufacturing and wood product processing. The fully automatic cutting machine receives pre-set processing instructions through a control system, and these instructions can be programs directly written by an operator in a numerical control system according to the size, shape, and processing requirements of the sheet. The control system drives the motor through a transmission system to drive the cutting head or the workbench to move along a predetermined trajectory and speed according to these instructions. During the movement, the cutting tool rotates at a high speed to perform precise cutting, grooving, drilling, and other processing operations on the sheet, thereby processing the sheet into the required shape and size.

[0033] A fully automatic cutting machine is provided, including: a frame 100, a drilling unit 200, a first clamping device 300, a first feeding device 400, a milling inner cavity unit 500, a second clamping device 310, a second feeding device 410, a cutting unit 600, a first gantry 700, a second gantry 710, a third gantry 720, and a control unit.

[0034] Multiple guide rails are provided on the frame 100. The first gantry 710 is arranged at the front end of the frame 100. The drilling unit 200 is slidably arranged on the first gantry 700. The first clamping device 300 and the second clamping device 310 are slidably arranged on the guide rails of the frame 100. The second gantry 710 is arranged in the middle of the frame 100. The milling inner cavity unit 500 is slidably arranged on the second gantry 710. The third gantry 720 is arranged at the rear end of the frame 100. The cutting unit 600 is slidably arranged on the third gantry 720. The first feeding device 400 and the second feeding device 410 are arranged on the side of the frame 100. The control unit is electrically connected to the drilling unit 200, the first clamping device 300, the first feeding device 400, the milling inner cavity unit 500, the second clamping device 310, the second feeding device 320, and the cutting unit 600 respectively.

[0035] As a further improvement of the above technical solution, in some further specific examples, the first clamping device includes a first lifting cylinder 301, a first mounting plate 302, a first clamping cylinder 303, a first driving motor 304, and a first fixing frame 305. The first clamping cylinder 303 is installed on the first mounting plate 302. The first mounting plate 302 is fixed to the telescopic end of the first lifting cylinder 301. The first lifting cylinder 301 is fixedly installed above the first fixing frame 305. The first driving motor 304 is installed on the side of the first fixing frame 305.

[0036] In this embodiment, the first driving motor 304 adopts an AC servo motor, which operates based on the principle of electromagnetic induction. When three-phase alternating current is applied to the stator winding, a rotating magnetic field is generated, which rotates at a synchronous speed. Under the action of the rotating magnetic field, the rotor generates an induced electromotive force and an induced current. The induced current interacts with the rotating magnetic field, thereby generating an electromagnetic torque that causes the rotor to rotate following the rotating magnetic field. By precisely controlling the magnitude, frequency, and phase of the current in the stator winding through a servo driver, the characteristics of the rotating magnetic field can be changed, and thus precise control over the motor speed, position, and torque can be achieved.

[0037] As a further improvement of the above technical solution, in some further specific examples, the second material clamping device 310 includes a second lifting cylinder, a second mounting plate, a second clamping cylinder, a second driving motor, and a second fixing bracket. The second clamping cylinder is installed on the second mounting plate, the second mounting plate is fixed to the telescopic end of the second lifting cylinder, the second lifting cylinder is fixedly installed above the second fixing bracket, and the second driving motor is installed on the side of the second fixing bracket.

[0038] A cylinder is a pneumatic actuator that converts the pressure energy of compressed air into mechanical energy and is widely used in the industrial field. When compressed air is introduced into the air inlet at one end of the cylinder, the pressure generated by the compressed air pushes the piston to move towards the other end, while the air at the other end is discharged from the exhaust port. By controlling the on-off of the air inlet and exhaust port and the direction of the incoming air, the reciprocating linear motion of the piston can be achieved, thereby driving the mechanism connected to the piston rod to perform corresponding actions.

[0039] As a further improvement of the above technical solution, in some further specific examples, the first feeding device 400 includes a first feeding cylinder 401, a first fixing assembly 402, and a first pressing plate 403. The first feeding cylinder 401 is hinged to the first fixing assembly 402, and the first pressing plate 403 is hinged to the telescopic end of the first feeding cylinder 401. As the first feeding cylinder 401 continuously extends, it drives the first pressing plate 403 to continuously move downward, directly pressing and fixing both sides of the material. A spring structure for buffering is provided at the top of the first pressing plate 403 to reduce excessive pressing on the material.

[0040] A spring is a mechanical part that utilizes elasticity to work, stores and releases energy through elastic deformation, or generates an elastic force to achieve functions such as buffering, shock absorption, and reset. The working principle of a spring is based on Hooke's law, that is, within the elastic limit, the elastic force of the spring is proportional to the elongation or compression of the spring. When an external force acts on the spring, the spring will deform and store elastic potential energy; when the external force disappears, the spring will return to its original state under the action of the elastic force and release the stored energy.

At the same time, the drill bit can also accurately control parameters such as the drilling position, depth, and speed through the control system to meet different processing requirements.
