[0019] In actual use, by placing an external object on the X-axis driving assembly 4, the first Y-axis driving assembly 2 and the second Y-axis driving assembly 3 drive the X-axis driving assembly 4 to move in the Y direction, and the X-axis driving assembly 4 drives the external object to move in the X direction.

[0020] In the above design, the entire gantry drive platform omits the accordion cover, which facilitates electrode heat dissipation, reduces the machine size, reduces assembly difficulty and maintenance costs, and at the same time, by setting the opening of the No. 1 stator 241 downward, it can replace the protective function of the accordion cover and effectively prevent debris and iron filings from falling into the interior of the electrode stator and affecting the operation of the electrode.

[0021] Specifically: Figure 2 As shown, the support seat 21 is provided with a through hole 210 extending along the X direction.

[0031] In the above design, by setting the cross beam 41 through a cavity, the deadweight of the cross beam 41 can be reduced, and at the same time, the stability of the cross beam 41 can be improved by designing the first cross plate, the second cross plate, the third cross plate and the partition.

[0032] To further explain in detail, it should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
