ABSTRACT:
A press and assembly machine has a die set which has guide posts securely mounted on a base plate, and a cylinder plate securely mounted on top portions of the guide posts, and a movable plate slidably mounted on the guide posts. A cylinder is mounted on the cylinder plate. A piston rod of the cylinder is connected to the movable plate. A pick-and-place device is mounted on the base plate. The pick-and-place device comprises a pair of guide rails mounted on the base plate at opposite sides of the lower die, opposite sliding members slidably mounted on the guide rails, a connecting member connecting the sliding members, a reciprocating cylinder for reciprocating the connected sliding members, and a plurality of gripping actuators provided on the opposite sliding members. The gripping actuator has opposite gripping cylinders, opposite gripping fingers operated by a piston rod of the corresponding cylinder for gripping a work. A parts-feeder is provided for feeding works one by one to the pick-and-place device. A sequence controller is provided for sequentially operating the machine for progressively pressing and assembling works.
