The braking (braking) action of the spindle mechanism 2 is stopped; otherwise, the piston 42 is pushed by the elastic member 牝3 to disengage the piston 42 from the disk 44, so that the spindle mechanism 2 can be driven to rotate by the first direct drive motor 3. X 'when the shaft head housing i is swung to a programmed angle', the second brake device 7 can be activated to allow hydraulic oil to enter the oil chamber 73' and thereby push the piston 72 forward to contact the disc %, which can also generate an instant Stop the axle head housing brake (brake) action. It can be seen that the direct-drive universal spindle head with hydraulic pressure braking mechanism can achieve the effect of precise and sensitive braking of the multi-faceted direct drive spindle head. In summary, the direct-drive universal spindle head with hydraulic brake mechanism has been practical and creative, and its technical means are also based on new:, 'suspect and efficacy and * planning It is true that it has been met, and it has been said that it has made reasonable progress to ^ for this purpose, according to the law, to propose a new type of special shot, but to ride the Xiao Bureau to give a detailed examination, and to grant the patent as a prayer, to the sense of virtue.
