[0014] The present invention will be further described below in conjunction with the drawings.
[0015] Such as figure 1 with figure 2 As shown, a dynamic compensation mechanism for the bottom dead center of a high-speed precision press includes a shaft 3 mounted on a connecting rod 6 through two cylindrical roller bearings 4 and a shaft seat 5. The shaft 3 has an eccentric structure in the middle. A worm 8 and a worm gear 9 mechanism are installed at one end of 3, the worm wheel 9 is connected to the shaft 3. The worm 8 is fixed to the connecting rod 6 through a bearing seat 7 and is connected to a servo motor 13 through an elastic flexible shaft 12, and the servo motor 13 is fixed in On the press machine body.
[0016] The eccentric part of the shaft 3 is connected with the central shaft 1 through the central bearing shell 2, and the transmission of the shaft 3 drives the central shaft 1 to rise or fall, and then drives the moving parts of the slider to rise or fall to realize ...
