<p>PROBLEM TO BE SOLVED: To provide a mounting device in which the falling of units can be quickly and precisely performed, the device is never shaken, the pressed degree of the flange part of a rubber ring can be known, no manual operation is required in the diameter extension of a cylindrical metal fitting, and the diameter extending work can be automatically terminated. SOLUTION: This device has a diameter extending jig 2 and a diameter extending machine 3. The diameter extending machine is formed of an elevating mechanism part 3A and a driving mechanism part 3B, the elevating mechanism part is formed of a fixed strut 40, a body outer cylinder 42, a pressing shaft 50 and a display mechanism. The driving mechanism part is formed of a case 70, a crank mechanism and ratchet mechanism, a driving motor 88, and a control member for detecting that the load added to a hook member reaches a set value by gradually moving up a main spindle vertically moved by the crank mechanism driven by the motor and rotated by the ratchet mechanism, and outputting a drive stop signal to the motor.</p> |
