The invention discloses an automatic broach mechanism with an electric spindle. An annular boss is arranged at the position, close to the bottom surface, of the outer cylindrical surface of an electric spindle rotor. The inner ring of a front-end bearing is installed on the electric spindle rotor. An inner spacer bush is arranged on the electric spindle rotor in a sleeving mode. The outer ring of the front-end bearing is installed in a stepped hole of an electric spindle outer shell. An end cover is installed on the bottom surface of the electric spindle outer shell. A shell is installed on the bottom surface of the electric spindle rotor. A groove is formed in the position, close to the outer surface, of the shell, and a dust ring is installed in the groove in the shell. A plurality of installation holes are evenly distributed in the bottom surface of the shell in the radial direction, compression springs are installed on pins, the pins are installed in the installation holes in the shell, a plurality of counter bores are formed in the shell, clamping jaws are installed in the counter bores in the shell through pin shafts and can rotate around the pin shafts, the bottom surfaces of the pins abut against the top end planes of the clamping jaws, and a conical hole is formed in the center axis of the shell.
Description
technical field [0001] The invention relates to the technical field of AC double swing head automatic broaching, in particular to an electric spindle automatic broaching mechanism. Background technique [0002] The CNC machine tool equipped with AC double pendulum angle CNC milling head can realize five-axis or multi-axis linkage function to meet the efficient and precise processing requirements of complex curved surface parts. At present, the automatic tool changer on the AC double swing head has complex tool change process, long tool change time, changes in accuracy after tool change and long adjustment time, poor reliability and stability, complicated tool change operation, and cannot meet the ever-changing industrial needs. , especially the needs of the machine tool industry with a high degree of automation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electric spindle automatic broaching mechanism for...
