IPC: B25J15/04
Filed: 1993-12-17
Abstract: PURPOSE:To facilitate connection and disconnection of a carrier finger by separating a ball from a slit part of a rigis shaft by an R lever. CONSTITUTION:A ball 9 fit in a clamp part 8 is inserted into a slit part 20 on the inside of two rigid shafts by moving an R lever 7 at the time of operation. Contact in three directions is made by having a contact point on a slope at about 60 degrees of the rigid shaft slit part 20 and combining it with a contact point of a spacer pin 10 on the bottom surface with a flange part 11. Strong clamping force is generated by small force by a circular arc wedge effect on the surface of the ball at the time of inserting the ball. The clamping force is maintained by adjusting thickness of the flange part 11 of the spacer pin 10 so as to prevent excess and shortage of the clamping force due to dispersion of treatment of the slit part 20 on the inside of the rigid shafts. Separation of a finger connecting and disconnecting adaptor is carried out by separating the ball 9 of the clamp part 8 on the heat end from the slit part 20 between the rigid shafts 6 by way of operating the R lever 7.
