[0029] The present invention provides an automatic loading CNC lathe, in which the connecting arm 7 of the manipulator 8 squeezes the slide bar 20, so that the slide bar 21 can automatically push out the bar 27 inside the material box 11, and then the manipulator 8 can clamp the extended bar 27 and automatically load it into the chuck 3, without manually loading the bar 27 into the chuck 3, thereby making the CNC lathe more convenient when turning the bar 27, and reducing the danger of using the CNC machine tool.

[0030] In another embodiment provided by the present invention, a knife rod 33 is provided at the bottom of the chuck 3, a blade 34 is fixed at the top of the knife rod 33, and the blade 34 is rhombus-shaped, so that after one tip of the blade 34 is damaged, the other tip can also be used, and a vertical rail 29 is provided at the bottom of the chuck 3, and a screw rod 30 is connected to the inside of the vertical rail 29 through a bearing, and a slider 31 is slidably connected to the inside of the vertical rail 29, and the slider 31 is connected to the screw rod 30 through a thread, and a connecting seat 32 is fixed to the outer wall of one side of the slider 31, and the bottom end of the knife rod 33 is connected to the connecting seat The seat 32 is fixed; a motor 37 is fixed to the bottom end of the vertical rail 29, and the output shaft of the motor 37 is connected to the screw rod 30 through a key, and the screw rod 30 is driven by the motor 37 to rotate, so that the screw rod 30 can drive the cutter bar 33 to extend the radial movement of the bar 27 through the slider 31, so that the blade 34 radially turns the bar 27; a mounting rail 217 is fixed to the inner wall of the bottom of the casing 1, and the interior of the mounting rail 217 is connected to the screw rod 218 through a bearing, and the exterior of the screw rod 218 is connected to the slider 28 through a thread, and the slider 28 is connected to the outer surface of the slider 28 through a thread. The block 28 is slidably connected inside the mounting rail 217, the bottom end of the vertical rail 29 is fixed to the slider 28, and the screw rod 218 can drive the vertical rail 29 to move horizontally when it rotates. The motor 219 is fixed to the bottom end of the vertical rail 29, and the output shaft of the motor 219 is connected to the screw rod 218 through a key. When the screw rod 218 is driven to rotate by the motor 219, the slider 218 can drive the tool rod 33 to extend the axial direction of the bar 27, so that the blade 34 performs axial turning on the bar 27; an extrusion plate 24 is fixed to one end of the slide bar 20, A pressure sensor 36 adapted to the extrusion plate 24 is fixed to the top outer wall of the cylinder body 10, and a push block 26 is fixed to one end of the slide rod 21; a control host 35 is fixed to the outer wall of one side of the casing 1, and the pressure sensor 36 is electrically connected to the control host 35 through a wire; when the extrusion plate 24 contacts the pressure sensor 36, the pressure sensor 36 transmits an electrical signal to the control host 35, so that the control host 35 controls the motor 9 to stop rotating, and at the same time, the control host 35 controls the manipulator 8 to clamp the rod 27 extending from the material box 11.

[0031] Working principle: When in use, when automatic loading is required, the chuck 3 is driven to rotate through the spindle box 2, so that the chuck 3 is oriented and stopped. At this time, the electric telescopic rod 15 drives the electric wrench 16 to move upward, so that the electric wrench 16 cooperates with the wrench insertion hole on the chuck 3, so that the chuck 3 is opened when the electric wrench 16 rotates, and then the motor 9 drives the screw rod 5 to rotate, so that the screw rod 5 drives the connecting arm 7 to approach the material box 11; when the connecting arm 7 contacts the extrusion plate 24, the connecting arm 7 presses the sliding rod 20 into the interior of the cylinder body 10, so that the cylinder The hydraulic oil in the body 10 flows into the inside of the cylinder body 2 12. At this time, the piston 22 in the cylinder body 12 drives the slide rod 21 to extend due to the pressure, so that the push block 26 at the end of the slide rod 21 pushes the rod 27 at the bottom of the arc 14, so that one end of the bottom rod 27 extends out of the material box 11; when the extrusion plate 24 contacts the pressure sensor 36, the pressure sensor 36 transmits an electrical signal to the control host 35, so that the control host 35 controls the motor 9 to stop rotating, and at the same time, the control host 35 controls the manipulator 8 to clamp the rod 27 extending from the material box 11; then Then, the motor 19 drives the screw rod 15 to rotate in the opposite direction, so that the manipulator 8 moves close to the chuck 3, and the bar 27 is drawn out from the inside of the material box 11 and loaded into the inside of the chuck 3; then the chuck 3 is locked by the electric wrench 16, so that the chuck 3 clamps and fixes the bar 27, and then the electric wrench 16 is driven away from the chuck 3 by the electric telescopic rod, and when the motor 2 19 drives the screw rod 2 18 to rotate, the slider 2 28 can drive the tool rod 33 to extend the axial direction of the bar 27 to move, so that the blade 34 axially turns the bar 27, and the motor 3 37 The screw rod 30 is driven to rotate, so that the screw rod 30 can drive the knife rod 33 to extend the radial direction of the rod 27 through the slider 31, so that the blade 34 radially turns the rod 27; when the connecting arm 7 is separated from the extrusion plate 24, the elastic force of the spring 25 drives the piston 22 to move inside the cylinder body 2 12, so that the hydraulic oil inside the cylinder body 2 12 can return to the inside of the cylinder body 10, and the slide rod 1 20 extends out of the cylinder body 10, and the slide rod 21 retracts into the cylinder body 2 12. At this time, the rod 27 inside the material box 11 will fall into the arc bottom 14 by gravity.
