Title:
DEVICE AND METHOD FOR INDEXING THE PHASE OF A CRANK PIN
Document Type and Number:
WIPO Patent Application WO/1997/019784
Kind Code:
A1
Abstract:
In a crank pin grinding machine, device and method for indexing the phase of a crank pin that can index the phase while a spindle is being rotating. The device comprises a pair of spindles (23, 24) disposed on a first axis ('alpha') so as to be separated away from and facing each other and adapted to be driven synchronizing with each other, a chuck main body (26, 27) provided on a leading end of each of the spindles for gripping a crank shaft (34) on a second axis ('beta') that is parallel to the first axis ('alpha'), a phase changing shaft (55) provided on the second axis ('beta') of at least one of the chuck main bodies for indexing crank pins (40-42) having different phase angles on the first axis ('alpha') and a phase indexing shaft (65) coupled to the phase changing shaft so as to be rotatingly driven concentrically with the spindles, the device being controlled such that a first mode in which the phase changing shaft is rotated in a synchronized fashion at the same speed as that of the spindles and a second mode in which the phase changing shaft is rotated in a synchronized fashion with a relative speed difference are effected.
