[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-precision CNC machining center with strong vibration resistance, comprising a base, a worktable on the base, a movable support platform for supporting the worktable below the worktable, a machine tool for supporting the movable support platform on the base, a Y-axis moving mechanism for driving the worktable to move along the Y-axis on the movable support platform, and an X-axis moving mechanism for driving the movable support platform to move along the X-axis on the machine tool. The Y-axis moving mechanism is relatively perpendicular to the column, and the X-axis moving mechanism is relatively parallel to the column.

[0005] As a further embodiment of this utility model: the Y-axis moving mechanism includes a first connecting member located under the worktable and a Y-axis driving assembly for driving the first connecting member to move along the Y-axis.

[0006] As a further embodiment of this utility model: the Y-axis drive assembly includes a first drive motor and a first screw connected to the drive shaft of the first drive motor.

[0007] As a further embodiment of this utility model: the X-axis moving mechanism includes a second connecting member located below the moving support platform and an X-axis driving component for driving the second connecting member to move along the X-axis.

[0008] As a further embodiment of this utility model: the X-axis drive assembly includes a second drive motor and a second screw connected to the drive shaft of the second drive motor. One end of the second screw passes through a second connector and is hinged to the machine base. The second connector is threadedly engaged with the second screw.

[0009] As a further embodiment of this utility model: a first slider is provided below the worktable, and a first slide rail is provided on the movable support platform to cooperate with the first slider. The worktable is slidably connected to the movable support platform through the first slider and the first slide rail.

[0010] As a further embodiment of this utility model: a second slider is provided below the movable support platform, and a second slide rail is provided on the machine platform to cooperate with the second slider.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7 A high-precision CNC machining center with strong vibration resistance includes a base 1, a worktable 11 on the base 1, a movable support platform 12 for supporting the worktable 11 below the worktable 11, a machine tool 13 for supporting the movable support platform 12 on the base 1, a Y-axis moving mechanism 2 for moving the worktable 11 along the Y-axis on the movable support platform 12, and an X-axis moving mechanism 3 for moving the movable support platform 12 along the X-axis on the machine tool 13. The Y-axis moving mechanism 2 is relatively perpendicular to the column 4, and the X-axis moving mechanism 3 is relatively parallel to the column 4. The X-axis moving mechanism is located below the Y-axis moving mechanism, so that the movable support platform can always be supported by the machine tool, ensuring that the vibration generated during machining can be transmitted to the machine tool and the base, thereby reducing the vibration experienced by the worktable.

[0027] In some embodiments, the Y-axis moving mechanism 2 includes a first connector 21 located under the worktable 11 and a Y-axis driving assembly 22 for driving the first connector 21 to move along the Y-axis. The Y-axis driving assembly 22 includes a first drive motor 221 and a first screw 222 connected to the drive shaft of the first drive motor 221. One end of the first screw 222 passes through the first connector 21 and is hinged to the movable support platform 12. The first connector 21 and the first screw 222 are threadedly engaged. The first drive motor 221 drives the first screw 222 to rotate. After the first screw 222 rotates, it will drive the first connector 21 to start moving along the Y-axis direction through thread engagement. After the first connector 21 starts moving, it will move the worktable 11 along the Y-axis direction, allowing the workpiece on the worktable 11 to move in the Y-axis direction.

[0028] In some embodiments, the X-axis moving mechanism 3 includes a second connector 31 located below the moving support platform 12 and an X-axis driving assembly 32 for driving the second connector 31 to move along the X-axis. The X-axis driving assembly 32 includes a second drive motor 321 and a second screw 322 connected to the drive shaft of the second drive motor 321. One end of the second screw 322 passes through the second connector 31 and is hinged to the machine base 13. The second connector 31 and the second screw 322 are threadedly engaged. 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 connector 31 along the X-axis through thread engagement, so that the second connector 31 can drive the moving support platform 12 to move, and thus drive the workpiece to move along the X-axis.

[0029] Specifically: the first drive motor 221 drives the first screw 222 to rotate. After the first screw 222 rotates, it drives the first connector 21 to move along the Y-axis through thread engagement. After the first connector 21 starts moving, it moves the worktable 11 along the Y-axis, allowing the workpiece on the worktable 11 to move in the Y-axis direction. After the second drive motor 321 starts, it drives the second screw 322 to rotate. After the second screw 322 rotates, it drives the second connector 31 to move along the X-axis through thread engagement, allowing the second connector 31 to move the movable support table 12, which in turn moves the workpiece along the X-axis. 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 tool 13 when moving along the X-axis. This ensures that the vibration generated by the workpiece on the worktable 11 during processing can be transmitted to the machine tool 13 through the movable support table 12, thereby minimizing the vibration experienced by the worktable 11 and ensuring the processing accuracy of the workpiece.

[0030] In some embodiments: a first slider 111 is provided below the worktable 11, and a first slide rail 121 that cooperates with the first slider 111 is provided on the movable support platform 12. The worktable 11 is slidably connected to the movable support platform 12 through the first slider 111 and the first slide rail 121. A second slider 122 is provided below the movable support platform 12, and a second slide rail 131 that cooperates with the second slider 122 is provided on the machine platform 13. The movable support platform 12 is slidably connected to the machine platform 13 through the second slider 122 and the second slide rail 131. The sliding connection between the first slider 111 and the first slide rail 121 allows the worktable 11 to move quickly when driven by the first connecting member 21, while the sliding connection between the second slider 122 and the second slide rail 131 allows the movable support platform 12 to move quickly when driven by the second connecting member 31.

[0031] In some embodiments: a column 4 is provided on the outer side of the base 1, and a machine head 5 is provided on the side of the column 4 near the worktable 11. The column 4 and the machine head 5 are slidably connected. A Z-axis moving mechanism 41 is provided on the column 4 for driving the machine head 5 to move along the Z-axis direction. The Z-axis moving mechanism 41 can drive the machine head 5 to move along the Z-axis direction, thereby enabling the workpiece to be processed in the height direction.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
