An idler pulley is set between the mounting plates and on one side of the synchronous pulley. The upper end of the synchronous belt is connected to the top plate, and the other end passes around the synchronous pulley and the idler pulley and then connects downward to the bottom plate.

[0007] Further: After the synchronous belt passes upward through the top plate, it is fixed by the upper fixing part.

[0018] See Figures 1 to 7 A Z-axis drive mechanism for a wind turbine blade grinding device includes a frame, which includes a top plate 11 located on the upper side and a bottom plate 12 located on the lower side, with two vertical rods 13 arranged between the top plate 11 and the bottom plate 12.

[0019] The grinding frame 2 is arranged between two vertical rods 13. The grinding frame 2 is connected to the vertical rods 13 through a sliding part 21 (there are two sliding parts, which are connected to the corresponding vertical rods respectively). The grinding frame 2 has two oppositely arranged mounting plates 22. A synchronous pulley 23 driven by a motor is set between the mounting plates 22. An idler pulley 24 is set between the mounting plates 22 and on one side of the synchronous pulley 23. The upper end of the synchronous belt 25 is connected to the top plate 11, and the other end passes around the synchronous pulley 23 and the idler pulley 24 and is connected downward to the bottom plate 12.

[0020] In this embodiment, the timing belt 25 passes upward through the top plate 11 and is fixed by the upper fixing part. The upper fixing part has an upper base 31, an upper side plate 32 is provided on the upper base 31, and an upper fixing plate 33 is provided on one side of the upper side plate 32. The timing belt 25 is arranged between the upper side plate 32 and the upper fixing plate 33 and is fixed by the upper fixing bolt 34.

[0021] In this embodiment, a lower fixing part is provided on the base plate 12. The lower fixing part has a lower base 41, a lower side plate 42 is provided on the lower base 41, and a lower fixing plate 43 is provided on one side of the lower side plate 42. The bottom of the synchronous belt 25 is arranged between the lower side plate 42 and the lower fixing plate 43 and is fixed by a lower fixing bolt 44.

[0022] The timing belt end is fixed by the upper and lower fixing parts, which provides a good fixing effect and facilitates the operation of the mechanism.

[0023] In this embodiment, the sliding part 21 (consisting of two units) has a sliding frame 211, at which a main sliding roller group and a secondary sliding roller group are arranged. The main sliding roller group has four circumferentially arranged main sliding rollers 212, and the secondary sliding roller group has secondary sliding rollers 213 arranged opposite to each other. The grinding frame moves up and down at the vertical rod via the sliding part.
