The invention discloses an auxiliary
material supply synchronizing mechanism of
metal powder additive manufacturing equipment. The auxiliary
material supply synchronizing mechanism comprises a frame body, a disc-shaped transverse mounting plate is fixedly installed on the upper portion of the frame body, a
barrel body is fixedly installed in the middle of the top of the mounting plate, a first vertical shaft is installed in the middle of the bottom of the
barrel body, the lower end of the first vertical shaft is movably connected with a bottom bearing in the
barrel body, a conical roller fixedly sleeves the position, close to the upper end, of the first vertical shaft, the small-
diameter end of the conical roller faces upwards, the lower end of the first vertical shaft is fixedly sleeved with a driven gear, the inner bottom of the barrel body is fixedly provided with a vertical power motor, an output shaft of the power motor is fixedly provided with a driving gear, and the driving gearis matched with the driven gear in a meshed mode. According to the auxiliary
material supply synchronizing mechanism, the output speeds of
metal powder particles in different material cylinders can be linearly controlled through adjustment of corresponding electric telescopic rods, and the whole mechanism only needs one power motor to provide the power; and therefore, the auxiliary material supply synchronizing mechanism is simple in structure and convenient to use.
