Shock-absorbing device for spindle headstocks |
摘要 |
The shock-absorbing device is intended to be mounted on the spindle headstock (10) of a machine tool. The spindle headstock (10) includes a motor driven spindle unit (11) connected to an upright by means of a support (12). The device comprises a yieldable structure (14,20) connected on the one side to the spindle unit (11) and on the other side to the support (12) and adapted to yield upon an accidental collision of the spindle headstock (10) against a workpiece. Collision sensor means are associated to the yieldable structure (14,20) for detecting the yielding thereof resulting from an accidental collision of the spindle headstock (10) against a workpiece and for transmitting in response a signal to a machine tool control unit. <IMAGE> |
