Abstract

The invention discloses a main shaft for a machining center machine, comprising a shaft core and a shaft seat, wherein the shaft core is combined together with the shaft seat through a 7014C bearing and a 7012C bearing; an outer ring of the 7014C bearing is pressed by using a front end cover and a first spacer bush through bolts on a ring flange; an inner ring of the 7014C bearing is fixed on the shaft core through a first locking nut and a second spacer bush; an outer ring of the 7012C bearing is not fixed; an inner ring of the 7012C bearing is fixed on the shaft core through a second locking nut, a first circular-arc toothed belt pulley and a dust resistant cover; an ejector rod is arranged in the shaft core; a four-valve jaw is arranged below the ejector rod; the ejector rod bears an upward action force of a disc spring through a nut and then transmits the upward action force to the four-valve jaw; the nut and a third locking nut are mutually fastened; the shaft core inputs a torque through the first circular-arc toothed belt pulley; and the first circular-arc toothed belt pulley and the second circular-arc toothed belt pulley are fixed on the shaft core and are positioned above the second locking nut. Compared with the prior art, the main shaft has a more reasonable structure.

Description

technical field [0001] The invention relates to a spindle, in particular to a spindle for a machining center. Background technique [0002] In CNC machine tools, whether it is a CNC lathe, drilling machine or milling machine, the spindle is the most critical component and plays a vital role in the accuracy of the machine tool. A Chinese patent once disclosed a "machining center machine spindle" (China, announcement number CN2838816Y, announcement date on November 22, 2006), which includes a main shaft seat, a main shaft in the main shaft seat, and a complete set of broaching claws in the main shaft , the tool handle in the whole group of broaching claws, the lower ball bearing, the thrust bearing, the upper ball bearing, the pulley, the upper cover of the main shaft seat on the upper end face of the main shaft seat, and the lower end of the main shaft seat on the lower end face of the main shaft seat The cover and the water throwing ring at the lower end of the main shaft, ...
