摘要:
Workpiece finishing apparatus including an abrasive charged trough in which workpieces are subjected to reciprocating movement along a desired path fixed by the shape of a traverse guide. The finishing trough is moveable vertically to position each workpiece in the abrasive. Mechanism is provided to automatically sequentially control the feeding, chucking, finishing and removal of workpieces.

An automatic recipro-finishing machine includes structure for conveying workpieces or workpiece holders, structure for engaging and disengaging the conveying structure with and from a conveying chain and structure for transferring the workpieces or workpiece holders from the conveying structure to the finishing apparatus or from the finishing apparatus to the conveying structure, together with the provision of a sequence control system for conveying the workpieces or workpiece holders, for mounting workpieces or the workpiece holders in the finishing apparatus, and for chucking and removal of the workpiece or the workpiece holders from the finishing apparatus.
摘要:
A method and an apparatus for finishing workpieces which are caused to flow in a helical motion together with abrasive media within a circular vibratory finishing tub in the form of a hollow annulus closed at both ends, and more particularly for vibratory finishing of workpieces together with abrasive media in a heavily compressed condition and for separating the mass (a mixture of workpieces and abrasive media) into workpieces and abrasive media. The apparatus has a downwardly inclined or horizontal circular vibratory finishing tub having an opening at the top which is closed in operation, in the form of a hollow annulus, having the radially greatest sectional area at the central portion thereof and the sectional area being gradually smaller toward both ends thereof, so that the mass is caused to flow during vibration with an increased density resulting in a substantially compressed condition of the mass so that workpieces and abrasive media are caused to move in a closely spaced relation which would otherwise be eliminated at every vibrating. By this arrangement the vibrating pressure and action between workpieces and abrasive media are improved and the mass separating efficiency as well as the smoothness of the finished surfaces are also improved considerably.

A vibration generating device for a vibratory machine has a reversible electric motor with at least two eccentric weights on the opposite ends of the shaft thereof, the position of which is automatically changeable upon reversal of the direction of rotation of the motor. The weights act during rotation of the motor to cause the machine to effect different vibratory motion depending on the direction of rotation of the motor.
