The saddle component 2 has a saddle groove, which extends along the Z direction. The ram component 3 is embedded in the saddle groove, and the saddle groove is used to accommodate the ram component 3 and the tool assembly 4.

[0026] When the fixed-wheelbase machine tool mentioned above is at a standstill, the motor component 1 drives the slide member 3 to rise in the Z direction relative to the saddle member 2, thereby driving the tool assembly 4 to rise until the tool assembly 4 is stored in the saddle groove. In this way, the space occupied by the machine tool is reduced and the tool assembly 4 is protected. During processing, the motor component 1 drives the slide member 3 to descend in the Z direction relative to the saddle member 2, thereby driving the tool assembly 4 to descend to realize processing of the workpiece. Since the tool assembly 4 is installed on the slide member 3, the movement of the slide member 3 does not affect the wheelbase of the tool assembly 4, thereby meeting the processing requirements without increasing the wheelbase of the tool assembly 4, avoiding the shaking of the tool assembly 4, and ensuring the processing accuracy of the tool assembly 4.

The saddle component 2 includes two saddle motors, which are respectively installed on the saddle body and arranged in a corresponding interval. The two saddle motors are synchronously arranged to mesh with the beam rack.

[0040] In this way, the two saddle motors synchronously output driving force to ensure sufficient driving force. At the same time, the two saddle motors correct each other.
