A mechanical tool spindle of Turning-Milling compound machining center has a motor and a tool shaft connected by a connecting shaft in the box body. Under the connecting shaft, there is a hydraulic locking device with three teeth discs. The locking device has a fixed teeth disc positioned in the box body and a movable teeth disc positioned on the tool shaft. The fixed teeth disc and the movable teeth disc have a ring hydraulic cylinder with the cylinder mouth opposite to the bottom of the fixed teeth disc, and the upper ring hydraulic cylinder in the upper ring hydraulic cylinder. The lower end face of the piston has two interlocking teeth discs which can mesh with the fixed teeth disc and the movable teeth disc respectively. The lower ring hydraulic cylinder is an inner and outer double ring hydraulic cylinder. The lower inner ring hydraulic cylinder has a lower inner ring piston, the lower outer ring hydraulic cylinder has a lower outer ring piston, the upper part of the lower inner ring piston has a ring piston rod which can be counteracted to the lower disc of the movable teeth disc, and the upper part of the lower outer ring piston is connected. Ring piston rod in double gear disc. The invention has a hydraulic locking device with three teeth discs in the tool spindle box body, which can conveniently lock the tool axle stably and does not need to be used with the tool sleeve processed separately.
