[0026] according to Figure 2 , Figure 4 and Figure 6 As shown, the ejection mechanism 7 includes an ejection plate 701, a roller 702, a two-way push rod 703, a trapezoidal block 704, a connecting rod 705 and a return spring 706. The built-in groove of the workbench 10 is provided with a two-way push rod 703, and rollers 702 are installed at both ends of the two-way push rod 703 through a movable shaft. A connecting rod 705 runs through the inside of the workbench 10 close to the two-way push rod 703, and a return spring 706 is sleeved on the outer side of the connecting rod 705. One end of the connecting rod 705 close to the roller 702 is connected to the trapezoidal block 704, and one end of the trapezoidal block 704 is slidably connected to the reserved groove on the inner wall of the workbench 10. The top of the connecting rod 705 is connected to the ejection plate 701, and the number of the connecting rod 705 and the return spring 706 are both four.

[0027] In specific implementation, when the workpiece is processed on the machine base 1 of the CNC machining center, it is necessary to take out the workpiece. The two-way push rod 703 can push the roller 702 to both sides, so that the roller 702 slides on the inclined surface of one side of the trapezoidal block 704, so that the roller 702 squeezes the trapezoidal block 704, and then the trapezoidal block 704 pushes the connecting rod 705 upward, and at the same time squeezes the reset spring 706 to contract, and then the connecting rod 705 pushes the ejector plate 701 upward, so that the ejector plate 701 drives the workpiece to rise and quickly ejects the workpiece, which can facilitate the staff to quickly take out the processed workpiece and improve the work efficiency of the CNC machining center.

[0028] according to Figure 1-5As shown, the rotating mechanism 11 includes a No. 2 motor 111, a moving block 112 and a connecting plate 113.

[0029] During specific implementation, since some CNC machining centers can only perform horizontal machining on the workpiece, it is not convenient to perform tilted machining on the workpiece, which reduces the machining efficiency, the No. 1 motor 904 can be used to drive the screw rod 902 to rotate, and then the slider 903 moves to one side on the screw rod 902 and drives the support rod 901 to rotate, so that the support rod 901 lifts one end of the workbench 10 upward, and at the same time, the other end of the workbench 10 rotates on the rotating seat 8, so that the inclination angle of the workbench 10 can be quickly adjusted, and then the No. 2 motor 111 drives the connecting plate 113 to rotate, so as to adjust the orientation of the workbench 10, and the moving block 112 slides on the No. 2 electric slide rail 12 to adjust the position of the workpiece, and the angle and orientation of the workbench 10 are adjustable, which improves the convenience of the CNC machining center.

[0030] Working principle: When using this CNC machining center that is convenient for ejecting and taking materials, first, set the parameters on the control panel, then place the workpiece to be processed in the placement slot 14 of the workbench 10, clamp the two ends of the workpiece through the clamping assembly 6, and then the moving block 112 slides on the No. 2 electric slide rail 12, so that the workbench 10 drives the workpiece to the bottom of the processing assembly 5, and then the processing assembly 5 performs cutting and other operations on the working surface. At the same time, the No. 1 electric slide rail 4 can drive the processing assembly 5 to move left and right. During the processing, the inclination angle and orientation of the workbench 10 can be adjusted by the rotating mechanism 11 and the angle adjustment mechanism 9 to meet different processing requirements.
