Abstract:The O fitting is by machine the core, an item jade and the bearing is composed, in which bearing uses the riveting to press the assembly.The task is to design a content automatic assembly workbench for the O fitting.The assembly process including machine the core fixed, item jade shipping with the laying aside, lower bearing shipping with the laying aside, the lower bearing riveting presses, the dry dust removal and withdraws not good.The bench is pided into two layers, the upper level is rotating table, and there are wheel drive, 1/8 wheel bearing and placed with eight clamps to place the parts.The lower level is the fixed work table, the laying aside has a series of manipulators, the manipulator mainly has the pneumatic actuator and using the air cylinder, the gas begins the fingernail, the air operated sucker lays aside and takes out the components.Rotary worktable, every turn one 8 weeks eight location on the manipulator work at the same time.Moreover the item jade automatic arriving location used the vibration hopper, the guide rail, the material place has caused the item jade docking at the reliable position.Bearing
riveting station using gas-liquid pressurized cylinder, effectively improve the work pressure.The whole equipment has fully used the detection technology, PLC technology, so that the electrical integration of the machine has been the perfect combination.
Key Words:Detection, Assembly, Pressure, Pressure riveting, Rotary table
