PURPOSE: To improve the damping effect on receiving and delivering by holding a projection formed onto a turret head by a clamping piece spring-urged to a body side in the receiving seat of a supporting arm and releasing the clamping by an unclamping mechanism at a replacement position.
CONSTITUTION: A turret head 11 which has been used is shifted with a holder not shown in the figure to a replacement position 20, and the projection 21 of the head 11 is inserted into a penetration hole 23b on the receiving seat 23 of a vacant supporting arm 5, and said projection 21 is caught by a clamping piece 24. The collision with the arm 5 accompanied by the shift at this time is absorbed by a spring 22. Then, the clamp of a head holder not shown in the figure is released, and the holder is retreated, and the turret head 11 in stock state is selected and shifted to the replacement position 20, and the clamping piece 24 is pushed and spread by an unclamping driving source 26. Therefore, the receiving seat 23 is press-attached onto the head, by the spring 22, and the turret head 11 is certainly installed. Therefore, the damping performance on replacement can be improved.
