[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-7, a CNC machining center with integrated machine head, comprising a base 1 and an integrated casting frame 4 located on one side of the base 1 and a machine head 5 movably arranged on one side of the integrated casting frame 4, the integrated casting frame 4 is provided with a vertically extending give way groove 41 and a vertical guide rail 6 extending vertically on one side of the machine head 5, the machine head 5 slides with the vertical guide rail 6, a machine head driving mechanism 7 for driving the machine head 5 to move is provided in the give way groove 41, a workbench 11 is provided on the base 1, a movable support table 12 for supporting the workbench 11 is provided below the workbench 11, a machine table 13 for supporting the movable support table 12 is provided on the base 1, the machine head 5 for machining a workpiece is installed through the integrated casting frame 4, the integrated casting frame 4 is an integrated casting, and the overall design reduces the installation and machining errors, and also makes it less likely for the machining center to shake during operation, effectively resists vibration, and effectively improves the stability of the machine head 5 when machining workpieces, thereby facilitating the machining accuracy of the machine head 5.

[0020] In some embodiments: two vertical guide rails 6 are provided on the integrated casting frame 4, and the make way groove 41 is located between the two vertical guide rails 6. The design of providing two vertical guide rails 6 on the integrated casting frame 4 and locating the make way groove 41 therebetween can effectively enhance the rigidity of the integrated casting frame 4, improve the movement accuracy and stability of the machine head 5 on the integrated casting frame 4, and at the same time optimize the positional spatial layout of the component structure on the integrated casting frame 4, so that the overall center of gravity of the integrated casting frame 4 and the machine head 5 is kept as much as possible in the middle position between the machine head 5 and the integrated casting frame 4, thereby ensuring the positional stability of the machine head 5, and further helping to improve the machining accuracy of the machine head 5 on the workpiece.

[0021] In some embodiments, the machine head driving mechanism 7 includes a transmission screw 71 extending vertically and a machine head driving motor 72 driving the transmission screw 71 to rotate. The machine head 5 is provided with a transmission seat 73 threadedly matched with the transmission screw 71. The threaded match between the transmission screw 71 and the transmission seat 73 can achieve high-precision transmission, ensuring the precise movement of the machine head 5 in the vertical direction. Due to the good stability of the screw transmission, the machine head 5 will not produce obvious vibration or shaking during the movement, which is conducive to maintaining the stability of the processing.

[0022] In some embodiments: the integrated casting frame 4 is provided with a plurality of hollow openings 42, and the design of the hollow openings 42 can significantly reduce the weight of the integrated casting frame 4, thereby reducing the overall mass of the machine tool, and reducing the weight helps to reduce the vibration and inertia force generated by the machining center during the machining process, and improve the machining stability. At the same time, through a reasonable hollow layout, the rigidity and stability of the integrated casting frame 4 can be enhanced, making it more resistant to external stress and deformation.

[0023] In some embodiments: a Y-axis moving mechanism 2 for driving the workbench 11 to move along the Y-axis is provided on the mobile support table 12, and an X-axis moving mechanism 3 for driving the mobile support table 12 to move along the X-axis is provided on the machine table 13. The Y-axis moving mechanism 2 is relatively perpendicular to the integrated casting frame 4, and the X-axis moving mechanism 3 is relatively parallel to the integrated casting frame 4. The X-axis moving mechanism 3 is located below the Y-axis moving mechanism 2, so that the mobile support table 12 can always be supported by the machine table 13, ensuring that the vibration generated during processing can be transmitted to the machine table 13 and the base 1, thereby reducing the vibration of the workbench 11.

[0024] In some embodiments: the Y-axis moving mechanism 2 includes a first connecting member 21 located under the workbench 11 and a Y-axis driving assembly 22 for driving the first connecting member 21 to move along the Y-axis. The Y-axis driving assembly 22 includes a first driving motor 221 and a first screw 222 connected to the driving shaft of the first driving motor 221. One end of the first screw 222 is connected to the first connecting member 21 and is hinged on the movable support platform 12. The first connecting member 21 is threadedly engaged with the first screw 222. The first driving motor 221 will drive the first screw 222 to rotate. After the first screw 222 rotates, it will drive the first connecting member 21 to start moving along the Y-axis direction through threaded engagement. After the first connecting member 21 starts to move, it will move with the workbench 11 along the Y-axis direction, so that the workpiece on the workbench 11 can move in the Y-axis direction.

[0025] In some embodiments: the X-axis moving mechanism 3 includes a second connecting member 31 located below the mobile support table 12 and an X-axis driving assembly 32 for driving the second connecting member 31 to move along the X-axis. The X-axis driving assembly 32 includes a second driving motor 321 and a second screw 322 connected to the driving shaft of the second driving motor 321. One end of the second screw 322 is connected to the second connecting member 31 and is hinged on the machine table 13. The second connecting member 31 is threadedly engaged with the second screw 322. After the second driving motor 321 is started, it will drive the second screw 322 to rotate. After the second screw 322 rotates, it will move the second connecting member 31 along the direction of the X-axis through threaded engagement, so that the second connecting member 31 can drive the mobile support table 12 to move, and then drive the workpiece to move along the direction of the X-axis.

[0026] Specifically: the first drive motor 221 will drive the first screw 222 to rotate. After the first screw 222 rotates, it will drive the first connecting member 21 to start moving along the Y-axis direction through thread engagement. After the first connecting member 21 starts to move, it will move the workbench 11 along the Y-axis direction, so that the workpiece on the workbench 11 can move in the Y-axis direction. After the second drive motor 321 is started, it will drive the second screw 322 to rotate. After the second screw 322 rotates, it will move the second connecting member 31 along the X-axis direction through thread engagement, so that the second connecting member 31 can drive the movable support table 12 to move, and then drive the workpiece to move along the X-axis direction. Because the X-axis moving mechanism 3 is located below the Y-axis moving mechanism 2, the movable support table 12 can always be supported by the machine table 13 when moving along the X-axis, ensuring that the vibration generated by the workpiece on the workbench 11 during processing can be transmitted to the machine table 13 through the movable support table 12, thereby minimizing the vibration of the workbench 11 and ensuring the processing accuracy of the workpiece.

[0027] As a further solution of the present invention: a waste material transmission mechanism 8 is provided on the base 1 and is located in the machine table 13. The waste material transmission mechanism 8 includes a feeding auger 81 and a waste material conveying motor 82 for driving the feeding auger 81 to rotate. The feeding auger 81 is parallel to the X-axis moving mechanism 3. The waste material transmission mechanism 8 is provided on both sides of the X-axis moving mechanism 3. The waste material transmission mechanism 8 can automatically collect and transmit the waste material generated during the processing without manual intervention, and can remove the waste material from the working area in time, thereby avoiding the influence of waste material accumulation on the working area.
