The automated batch tapping device for machining pump caps of multistage centrifugal pumps of claim 8, wherein: the device further comprises a controller, wherein the controller is respectively connected with the first servo motor, the second servo motor, the electromagnetic clutch, the transverse push rod, the supporting push rod and the vertical push rod.
10. An automatic batch perforating method for a combined pump cover of a multistage centrifugal pump, which is realized by an automatic batch perforating device based on the processing of the pump cover of the multistage centrifugal pump according to claim 9, and is characterized by comprising the following steps:
1) The clamping mechanism is provided with a feeding station, a drilling station, a dust removing station and a discharging station, the expanding sleeve workpiece is arranged on a fourth rotating shaft at the feeding station by using a manipulator, and the first servo motor is controlled to work by using a controller, so that the expanding sleeve workpiece is transferred to the drilling station;
2) The controller controls the transverse push rod of the inner supporting mechanism to work, the transverse push rod drives the support pipe to move to the outer side of the fourth rotating shaft at the drilling station through the movable mounting plate, and the support push rod on the support pipe acts, so that the support block is abutted against the inner side of the expansion sleeve workpiece to provide inner supporting;
3) The controller controls the vertical push rod of the perforating mechanism to act, and simultaneously starts the drill rod, so that the drill rod perforates the annular expanding sleeve in the expanding sleeve workpiece; when one row of perforating actions is completed, the drill rod is reset, the controller controls the second servo motor in the clamping mechanism to rotate, and the electromagnetic clutch corresponding to the drilling station is electrified, so that the sleeve-expanding workpiece is overturned for a certain angle, and the perforating operation of the next row can be performed according to the flow;
4) When the expanding sleeve workpiece completes the opening operation of all opening points, the controller firstly controls the inner supporting mechanism to reset, and then controls the first servo motor to rotate, so that the expanding sleeve workpiece is transferred to a dust removing station, and the dust removing operation is performed by using an external blower; the controller controls the first servo motor to rotate again, so that the sleeve-expanding workpiece is transferred to the blanking station, and the sleeve-expanding workpiece is transferred to the storage area by using the manipulator.
