Cam-controlled main shaft lifting and rotating mechanism

Abstract

The utility model discloses a cam-controlled main shaft lifting and rotating mechanism, which aims to solve the problems that the lifting and rotating functions of the existing earphone production equipment are generally independently designed, the cost is higher, and the occupied space is larger. The mechanism comprises a mounting plate, a divider station and a rotating platform, a main shaft is fixedly connected to the middle of the lower surface of the rotating platform, the bottom end of the main shaft penetrates through the divider station and is fixedly connected with a fixing block, a connecting rod is arranged at the bottom end of the divider station, and a motor is mounted on the upper surface of the mounting plate. The first cam enables the fixing block to ascend and descend through the first transmission assembly in the rotating process, meanwhile, the second cam enables the station of the divider to rotate through the second transmission assembly in the rotating process, the first cam and the second cam are integrated and controlled through the first cam and the second cam, two sets of driving structures do not need to be independently designed, and the working efficiency is improved. The production cost is reduced, the occupied space of the structure is small, and the stability is better.
