A CNC drilling machine for impeller machining

Abstract

This utility model relates to the field of drilling machine technology and discloses a CNC drilling machine for impeller machining, including a working slide table. A first electric slider is arranged above the working slide table, and a rotary motor is fixedly installed on the upper side of the first electric slider. A fixed chuck is fixedly installed at the output end of the rotary motor. Three first sliding grooves are opened on the side of the fixed chuck, and first sliding blocks are slidably installed inside the first sliding grooves. In this utility model, when the impeller shaft is fitted into the mounting ring, the six first pressing blocks, under the action of torsion springs, adaptively press the shaft surface through the connecting blocks to complete the initial fixation. The three first sliding blocks advance synchronously along the first sliding grooves, forcibly correcting the impeller shaft to the center of the fixed chuck within seconds. The mounting ring is slidably connected to the third sliding groove of the first sliding block through the third sliding block. Tightening the second threaded post can lock it in place. Compared with the traditional three-jaw chuck, the manual correction step is eliminated, and the clamping efficiency is improved.
