[0003] At present, domestic automatic rifles are generally continuous-fire rifles that rely on gunpowder gas pressure and spring force to complete a series of actions such as pushing bullets, locking, firing, ejecting shells and feeding bullets. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a motor-driven firearm automatic machine and a working method thereof. The present invention has the characteristics of simple structure, novelty, strong practicality, reliable operation, etc., and is widely applicable to the use of various electric shock-firing firearms.

[0005] The object of the present invention is achieved in that:

[0006] A motor-driven firearm automatic machine comprises a receiver assembly, a frame assembly and a head assembly, wherein the frame assembly is installed in the receiver assembly, the head assembly is connected to the frame assembly, a transmission screw is installed in the receiver assembly via a bearing, a transmission nut is threadedly matched on the transmission screw, the frame assembly is fixedly connected to the transmission nut, a motor is installed at the end of the receiver assembly, and the rotating shaft of the motor is connected to the transmission screw.

[0007] Preferably, a position proximity switch is installed in the casing assembly, and when the head body is locked in place, the position proximity switch sends a signal.

[0008] Preferably, the receiver assembly is provided with a power-on assembly, the power-on assembly has contacts, the power-on assembly is connected to a power source, the head assembly is provided with a power-on rod, the power-on rod is used to trigger an electric firing bullet, and when the head body is locked in place, the power-on rod contacts the power-on assembly to energize.

[0009] A working method of a motor-driven firearm automatic machine,

[0010] After the motor is powered on, it drives the transmission screw to rotate. When the transmission screw rotates, it drives the transmission nut to make a linear motion. The transmission nut drives the frame assembly and the head assembly to make a linear motion along the casing assembly. The head assembly pushes the bullet into the chamber during the movement. After that, the frame assembly and the head assembly continue to move forward for a distance along with the transmission nut. The joint sleeve in the casing assembly forces the head body in the head assembly to lock.

[0011] After the locking is in place, the motor stops rotating, the power-on assembly contacts the power-on rod in the nose assembly, energizes, and performs electric firing, and the shell is ejected through the ejector in the nose assembly.

[0012] After the electric shock is completed, the motor reverses, the transmission nut drives the machine head body to unlock, and drives the machine frame assembly and the machine head assembly back to the starting position.

[0013] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0014] The invention adopts a motor to drive a transmission screw rod to drive a firearm automatic machine to complete the automatic machine structure of electric firing, bullet pushing, locking, firing, shell ejection and bullet feeding. The structure is simple, novel and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings.

[0023] See also Figure 1-Figure 5, a motor-driven firearm automatic machine, after the motor is powered on, it drives the transmission screw 3, and the transmission nut is installed on the transmission screw 3. When the transmission screw 3 rotates, it drives the transmission nut to move. The frame assembly 1 is fixedly connected to the transmission nut through two pins, and moves linearly in the receiver assembly together with the transmission nut; the head assembly 2 is installed in the frame assembly 1, and moves in the receiver assembly along with the frame assembly 1, and pushes the bullet into the chamber. At this time, after the frame assembly 1 and the head assembly 2 continue to move forward for a distance along with the transmission nut, the section sleeve in the receiver assembly 15 forces the head body in the head assembly 2 to lock (the principle of locking by the section sleeve is the same as the prior art), and after locking in place, the position proximity switch sends a signal, and the motor stops rotating; the power-on assembly 17 contacts the power-on rod 12 in the head assembly, powers on, and performs electric firing. Continue to power on, the motor reverses to drive the head to unlock and return to the starting position.
