When the servo motor is started, the servo motor drives the rotating rod to rotate, thereby driving the movable rod to slide in the arc groove. At this time, the connecting rod and the material picking assembly also make an arc motion with the movable rod. When the movable rod drives the material picking assembly to move to the leftmost end of the arc groove, the material picking operation is completed, and when the movable rod drives the material picking assembly to move to the rightmost end of the arc groove, the feeding operation is completed.

Start the servo motor 3, and the servo motor 3 drives the rotating rod 4 to rotate, thereby driving the movable rod 6 to slide in the arc groove 7. At this time, the connecting rod 9 and the material picking assembly also make an arc motion with the movable rod 6. When the movable rod 6 drives the material picking assembly to move to the leftmost end of the arc groove 7, the material picking operation is completed, and when the movable rod 6 drives the material picking assembly to move to the rightmost end of the arc groove 7, the feeding operation is completed. This reciprocating process can realize the continuous feeding operation of the CNC lathe.

[0022] Reference Figure 1 and Figure 3 The material taking component includes a U-shaped plate 10 fixedly connected to the bottom of the connecting rod 9, and a forward and reverse motor 11 is fixedly connected to the outer wall of one flange of the U-shaped plate 10. The output end of the forward and reverse motor 11 passes through the flange of the U-shaped plate 10 and is fixedly connected to a bidirectional screw rod 12. The external thread of the bidirectional screw rod 12 is connected to a slider 13, and the bottom of the slider 13 is fixedly connected to a clamping plate 14. When the workpiece needs to be clamped, the forward and reverse motor 11 is started, and the forward and reverse motor 11 can drive the bidirectional screw rod 12 to rotate, and the rotation of the bidirectional screw rod 12 drives the external thread of the bidirectional screw rod 12 to rotate. The two sliders 13 and the clamping plate 14 are close to each other, and the top wall of the slider 13 is tightly fitted with the inner wall of the web of the U-shaped plate 10, thereby preventing the slider 13 from rotating and deviating when the external bidirectional screw rod 12 moves. The two clamping plates 14 are close to each other to achieve clamping and picking of workpieces of different sizes. When the movable rod 6 drives the picking assembly to the rightmost end of the arc groove 7, the forward and reverse motor 11 reverses, driving the bidirectional screw rod 12 to reverse, so that the two sliders 13 and the clamping plates 14 move away from each other, releasing the workpiece, and realizing the loading of the workpiece.

[0026] The implementation principle of a material picking mechanism of a machining center in the embodiment of the present application is as follows: start the servo motor 3, and the servo motor 3 drives the rotating rod 4 to rotate, thereby driving the movable rod 6 to slide in the arc groove 7. At this time, the connecting rod 9 and the material picking assembly also make an arc motion with the movable rod 6, and the connecting rod 9 can make a lifting motion relative to the limit block 16. The limit block 16 can prevent the connecting rod 9 from being offset during movement, thereby increasing the stability of the material picking assembly during material picking and unloading. When the movable rod 6 drives the material picking assembly to move to the leftmost end of the arc groove 7, the material picking operation is completed. When the movable rod 6 drives the material picking assembly to move to the rightmost end of the arc groove 7, the loading operation is completed. This reciprocating process can realize the continuous loading operation of the CNC lathe. When the workpiece needs to be clamped, start the forward and reverse motors 11 The forward and reverse motor 11 can drive the bidirectional screw rod 12 to rotate. The rotation of the bidirectional screw rod 12 drives the two external sliders 13 and the clamping plate 14 to approach each other. The top wall of the slider 13 is tightly fitted with the inner wall of the web of the U-shaped plate 10, thereby preventing the slider 13 from rotating and deviating when the external bidirectional screw rod 12 moves. The two clamping plates 14 are close to each other to achieve clamping and picking of workpieces of different sizes. The arc-shaped protrusion 18 can increase the friction between the clamping plate 14 and the workpiece, thereby increasing the stability of the clamping plate 14 when clamping the workpiece. When the movable rod 6 drives the material picking assembly to move to the rightmost end of the arc groove 7, the forward and reverse motor 11 reverses, driving the bidirectional screw rod 12 to reverse, so that the two sliders 13 and the clamping plate 14 move away from each other, releasing the workpiece, and realizing the loading of the workpiece.
