<p>PURPOSE:To easily and surely insert and remove a pin automatically by supporting by a supporting mechanism a supporting member positioned for the axial center of the pin following the fitting action of a position detecting member for the pin. CONSTITUTION:In the case of inserting and removing a pin 4 for mounting a door to an automobile body, first when a sensing pawl 2 is moved in a direction Y, by an air cylinder 11 the pin is moved in a direction X being guided by an opening part 2a, the respective moving amounts are defected by a potentiometer, and a position of the pin 4 is calculated and stored. Next a pin retaining pawl 8 is moved downward by an air cylinder 40, the pin 4 inserted into holes 3, is removed with its one end of the pin pressed in the direction of the axial center. A tapered part 4a on the other end of the pin 4 is engaged with a pin insertion pawl 10 and its engaging hole 10a so as to hold the pin 4 by advancing a pin clamping pawl 9 by an air cylinder 43. On the contrary, in the case of inserting the pin 4 again, the pin is inserted by the reverse action based on a memory position. Thus, the pin can be easily and surely inserted and removed automatically.</p> |
