In this embodiment, a hydraulic station 90 is disposed on one side of the mounting frame 20, where the hydraulic station 90 provides power for loosening tools or clamping tools of the spindle 42 and clamping the turntable 30 or loosening the turntable 30 by a brake disc of the turntable 30, and the clamping or loosening process is smooth in a hydraulic manner, so as to avoid damage to the tools or the turntable 30 caused by sudden concentration of clamping force.

In the case that the horizontal five-axis machining center 1 is defined or not defined and further comprises a hydraulic station 90, the fastening member is an end toothed disc, the driving mechanism further comprises a pneumatic brake member, the pneumatic brake member is in driving connection with the end toothed disc, and when the horizontal five-axis machining center 1 starts a milling function, the pneumatic brake member keeps the end toothed disc and the main shaft 42 in a loose state, so that the main shaft 42 can freely rotate. When the turning function is started by the horizontal five-axis machining center 1, the fluted disc at the driving end of the pneumatic brake piece locks the main shaft 42, and the main shaft 42 stops rotating and keeps a stable and motionless state. By locating the end tooth disc inside the spindle 42, the volume of the horizontal five-axis machining center 1 is reduced. The bearing seat is sleeved on the outer side of the main shaft 42, the processing assembly 40 further comprises a shell 41, a bearing disc is arranged in the shell 41, and the shell 41 is arranged on the outer side of the main shaft 42 through the matching connection of the bearing disc and the bearing seat so as to form a protection effect on the main shaft 42.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
