Step 1, carrying mechanism are moved to the underface of the workpiece bearing device of pickup position, and control cylinder (3) drives push rod
(31) it pushes to the right, push rod (31) will drive two the second locating rods (103) to close up by connecting rod (9), so that floating
Plate (7) is in quick condition；
Step 2, carrying mechanism slowly rise, and positioning pin (51) is made to be inserted into the pin hole of workpiece bottom；
Step 3, carrying mechanism continue to rise, and workpiece is made to completely disengage the restriction range of workpiece bearing device；
Step 4 drives push rod (31) to pull to the left by controlling cylinder (3), and push rod (31) will drive two by connecting rod (9)
Second locating rod (103) detaches so that two the second locating rods (103) abut against the second locating shaft (104), so that floating
Movable plate (7) is in centering positioning states；
Step 5, carrying mechanism are moved horizontally to the surface for the workpiece bearing device for putting part position, are pushed away by cylinder (3) drive
Bar (31) pushes to the right, again so that float plate (7) is in quick condition；
Step 6, carrying mechanism slowly decline, and so that workpiece insertion is put the workpiece bearing device of part position, and continue to drop to positioning
After the pin hole for selling (51) disengaging disengaging workpiece bottom, carrying mechanism level is removed, and the carrying of workpiece is completed.
