Die adjusting device of high-speed punching machine

Abstract

The die adjusting device of the high-speed punching machine comprises a guide column, a worm gear and a worm, an inwards-concave installation groove is formed in the top of the guide column and matched with the worm gear, the worm gear is installed in the installation groove and comprises a gear disc and a rotary disc, the gear disc is arranged above the rotary disc, the outer diameter of the gear disc is smaller than that of the rotary disc, and the rotary disc is arranged in the installation groove. A pressing plate is arranged above the installation groove to fixedly arrange the rotary disc in the installation groove, the pressing plate and the guide column are fixedly installed, the worm is rotationally connected to one side of the gear disc of the worm wheel and connected with the gear disc in a meshed mode, the worm is fixedly connected with the pressing plate through an installation base, and the worm is rotationally installed in the installation base. According to the die adjusting device of the high-speed punching machine, the structural layout is compact, the worm gear and the worm are installed through the pressing plate and the installation base respectively, the weight of the pressing plate is greatly reduced compared with a traditional fixing block, the movement speed and accuracy of the high-speed punching machine can be effectively guaranteed, in addition, the center distance between the worm gear and the worm can be finely adjusted through the installation base, and the die adjusting effect is good. The requirement for the machining precision of parts can be reduced to a great extent, and meanwhile accumulated tolerance can be eliminated.
