Detailed Description

The following examples are presented to enable those skilled in the art to more fully understand the present invention, but are not intended to limit the invention in any way.

As shown in fig. 1, a flanged hole of the through shaft 2 to be processed is formed right below the cutter bar 1 of the electric drill, the large gear motor 43 is mounted on the octagonal shell 4, and the rotary table driving motor 51 is mounted on the long shell 5. Note that the other 7 working devices are omitted from the dashed line of the eight-sided housing 4 in the drawing.

As shown in fig. 2, a flange hole of the processed through shaft 2 is aligned under the electric drill holder 1, and the clamping cylinder 3 can clamp the flange of the processed through shaft 2. The corner pinion 32 and the corner small shaft 33 are rigidly connected, the corner pinion 32 and the corner small shaft 33 are hollow, and the corner pinion 32 and the corner large gear 41 are engaged. The corner pinion 32 has 32 teeth and the corner bull gear 41 has 128 teeth. The bull gear motor 43 is connected to the corner bull gear 41. The left end of the driving gear 55 is connected with a gear chain 56, and the upper end is connected with a turntable driving motor 51.

As shown in fig. 3, a corner large gear 41 is installed in the middle of the inside of the octagonal casing 4, a large gear shaft 42 is connected to the upper end of the corner large gear 41, 8 corner small gears 32 (only one is shown in the figure) are uniformly distributed around the corner large gear 41, and when the corner large gear 41 rotates, the 8 corner small gears 32 can be driven to synchronously rotate, and the position of the flange hole is adjusted.
