Referring to fig. 1, which schematically illustrates a structural diagram of a rotary lifting reciprocating mechanism 100 according to an embodiment of the present application, the rotary lifting reciprocating mechanism 100 includes a driving assembly 10 and a fixing assembly 20, the fixing assembly 20 includes a fixing table (not shown) and a gear 210, the fixing table is fixed on the gear 210 and rotates along with rotation of the gear 210, the fixing table is used for placing and fixing a workpiece, the driving assembly 10 is disposed opposite to the fixing assembly 20 and includes a driving member (not shown), a driving eccentric 110, a driven eccentric 120, a transmission member 130, a connecting rod 140 and a rack 150, the driving eccentric 110 is in transmission connection with the driving member, the driven eccentric 120 is connected with the driving eccentric 110 through the transmission member 130, the driving member drives the driving eccentric 110 to rotate, and the driving eccentric 110 drives the driven eccentric 120 to rotate through the transmission member 130; two connecting rods 140 are provided, wherein one end of one connecting rod 140 is fixedly connected to the driving eccentric wheel 110, the other end is fixedly connected to the rack 150, one end of the other connecting rod 140 is fixedly connected to the driven eccentric wheel 120, and the other end is fixedly connected to the rack 150; the rack 150 is engaged with the gear 210.
By arranging the driving eccentric 110 and the driven eccentric 120 and connecting the driving eccentric 110 and the driven eccentric 120 to the rack 150 through the connecting rod 140, the driving member drives the driven eccentric 120 to rotate together when driving the driving eccentric 110 to rotate, and the center of a circle rotates around a preset track when the driving eccentric rotates. Since the connecting rod 140 is fixed to the driving eccentric 110 and the driven eccentric 120, when the driving eccentric 110 and the driven eccentric 120 rotate, one end of the connecting rod 140 fixed to the driving eccentric 110/the driven eccentric 120 rotates along a predetermined track, thereby pushing the connecting rod 140 to move. When the connecting rod 140 moves, the rack 150 is driven to move, and when the driving eccentric wheel 110 and the driven eccentric wheel 120 rotate for one circle, the rack 150 completes one reciprocating motion. The reciprocating motion of the rack 150 can be divided into vertical movement and horizontal movement, the gear 210 is engaged with the rack 150, the movement process of the rack 150 in the horizontal direction pushes the gear 210 to rotate, the movement of the gear 210 in the vertical direction is matched with the rotation of the gear 210 to push the gear 210 to lift, so that the fixed assembly 20 realizes the rotary lifting operation.
In a specific embodiment, the driving member can be a cylinder, an electrode or a steering engine, and a driver with a small volume is preferred. Of course, larger drives may be submitted.
