Detailed ways

The technical solutions of the present utility model are further described clearly and completely below in conjunction with the accompanying drawings.

Referring to the accompanying drawings 1-4, the workbench is equipped with a rotating polygonal workbench 3 on the top of the base 1, the two sides of the rotating polygonal workbench 3 are respectively equipped with an auxiliary workbench 2, and the bottom in the base 1 is equipped with a servo motor 7, The output shaft 6 of the servo motor 7 is connected with the reducer 8. The output end of the reducer 8 is equipped with a bearing seat 11, the bearing seat 11 is equipped with a bearing 9, and a rotary table locking oil cylinder 10 is symmetrically installed on the bearing seat 11. , The upper end of the bearing 9 is equipped with an encoder 5, and the encoder 5 is connected with the table drive shaft 4 installed in the middle of the rotating polygon table 3.

The encoder 5 installed in the worktable can perform the indexing operation of 0-360 degrees for the rotation angle of the rotating polygonal worktable 3 .

The rotary table locking oil cylinder 10 mounted on the bearing seat 11 in the worktable is connected with the hydraulic control unit of the machining center by an oil pipe.

Before the workpiece is processed, the workpiece is clamped and leveled on the rotating polygon table 3, and then according to the process requirements on the drawing, the processing data and processing parameters are input into the control unit of the machining center, and the control center inputs the indexing requirements of the workpiece into the in encoder 5. During processing, the servo motor 7 installed in the base 1 starts to work after receiving the command from the control center. The motor output shaft 6 of the servo motor 7 drives the reducer 8 to work, and the transmission shaft of the reducer 8 drives and installs it on the bearing seat 11.
