Vertical lifting mechanism for numerical-control lifting platform milling machine

Abstract

The invention relates to a vertical lifting mechanism for a numerical-control lifting platform milling machine and belongs to the technical field of electromechanical equipment. The vertical lifting mechanism comprises an output motor and a transmission shaft, wherein an output shaft of the output motor is connected with a first cone gear, the transmission shaft and the output shaft of the output motor are vertically arranged, a second cone gear is connected to the transmission shaft, the second cone gear is engaged with the first cone gear, bearings are respectively arranged at the two ends of the transmission shaft, and one end of the transmission shaft is further connected with a toothed belt wheel. When the vertical lifting mechanism works, the output motor rotates to drive the first cone gear to rotate, the first cone gear and the second cone gear are in engaged transmission, and then, the transmission shaft rotates; and through the transmission of a toothed belt, a lead screw nut is rotated, and thus, the vertical lifting of a lifting platform is realized. According to the vertical lifting mechanism for the numerical-control lifting platform milling machine, a group of cone gears is adopted outside the lifting platform, so that the coefficient of complexity of lifting platform processing is greatly reduced, the operation is convenient, the tooth-side gap for the cone gears is reduced as much as possible, and the locating accuracy and re-locating accuracy for vertical lifting are then improved.
