Therefore, based on the above needs, the present embodiment provides a gantry device 100 of a grinding and polishing equipment.

[0033] Please refer to Figures 1 to 8 The present embodiment discloses a gantry device 100 of a grinding and polishing equipment, which comprises a gantry support 11, a first lifting mechanism 12 and a second lifting mechanism 13 connected to the gantry support 11, the first lifting mechanism 12 and the second lifting mechanism 13 are arranged vertically and parallel to each other; the first lifting mechanism 12 and the second lifting mechanism 13 each comprise a double-rail driving unit. The lifting mechanism of the gantry device 100 of the grinding and polishing equipment of the present embodiment adopts a double-rail driving unit, which greatly improves the stability of the operation of the grinding and polishing tool and the precision of the lifting action, and is beneficial to the grinding and polishing quality and effect of the automatic grinding and polishing equipment.

[0034] As Figure 2 shown, the gantry support 11 comprises a first column 112, a second column 113, and a cross arm 111 connected to the top ends of the first column 112 and the second column 113 at both ends; the first lifting mechanism 12 is connected to the first column 112, and the second lifting mechanism 13 is connected to the second column 113.
