ない問題を解決することにある。The above-mentioned prior art cannot be applied to a processing machine equipped with a press because a mechanism for raising and lowering the table itself is not added. It is an object of the present invention, as a processing machine equipped with a press, to float from a bolster of a press when a table rotates and to receive a punching shear force by the bolster of the press when the table descends. Another object of the present invention is to solve the problem that the rotation angle of the table in the conventional cam mechanism is limited to one direction and the selection angle is not minimized.

保つ。[Operation] A servo motor, a harmonic reducer, and a cross roller bearing are used for high-speed and high-accuracy indexing, and each gain and set time are stable in order to ensure accuracy against inertia during acceleration / deceleration. I can. In addition, absolute control is adopted to stabilize the accuracy during long-term operation. The table is raised by an air cylinder with a ball, and a linear bearing maintains accuracy and rigidity.

可能である。1 and 2 are a sectional view and a plan view of an embodiment of an index table and a sheet metal punching machine according to the present invention. The table 1 having eight stations, including the mold 8, weighs 3 tons. When a mold is selected, the ball cylinder air cylinder 7 raises the entire drive mechanism of the table 1, the servomotor 2, the harmonic speed reducer 3, the coupling 4, and the cross roller bearing 5 by 2 mm using the linear bearing 6 as a guide.

Rotation speed is 4.6s on average, 4.3s minimum, 8.8 maximum
Rotate at s to perform indexing with high accuracy of 175 μrad (36 ″).
Is received by the bolster 9a and the table receiver 10. Then, the material 11 which is a hoop material is sent by the NC level 12 and processed by the press 9. The processed work is further sent by the NC level 12 and cut by the shearing unit 13. Index tables are used in all industrial fields. The present invention is applicable as a production facility that cannot be simply rotated.
