摘要:
A rotation processing machine, including a rotating device that holds and rotates a workpiece; a processing device on which a cutting tool is mounted to process the workpiece; and a turning loader that has grippers arranged about a turning central axis, and that turns so that the grippers sequentially face the rotating device. The turning loader is configured to deliver and receive the workpiece to and from the rotating device by turning with the workpiece being directly or indirectly held by the gripper, and to deliver and receive the cutting tool to and from the processing device by turning with the cutting tool being directly or indirectly held by the gripper.

An apparatus for the transport of rollable workpieces, in particular gears, with a conveyor chain which extends over two return points, on the upper reach of which chain the workpieces rest or roll. Between two horizontal sections of the upper chain reach, which sections lie in different planes, there is provided an inclined section, in the area of which lies the clamping and machining station of a machine tool, to which roll the workpieces. The inclination of this section is changeable by means of a rocker arm, in order to be able to adjust the distance between the clamping device and the conveyor chain to various workpiece dimensions.

A sliding member having two gripping devices removes a finished workpiece from a machine and at the same time introduces a blank workpiece. The sliding member carries out a rectilinear feed and return movement, for which it is hydraulically driven. All movements of the two gripping device systems are controlled by cams, including (1) opening and closing the finished part gripping device when picking up the finished part, (2) swivelling the finished part gripping device approximately 90.degree., (3) opening and closing the blank gripping device as the sliding member is returned, (4) again erecting the finished part gripping device when outside of the machine, and (5) stabilizing the blank and finished part gripping devices during movement of the sliding member. To this must be added, if the workpiece is a gear which is to engage a gearlike tool, determining when the workpiece and tool have not meshed and then effecting a repetition of the approach while securely maintaining the blank workpiece in the blank gripping device.

An article exchange apparatus which can be used in an auto-loader having an exchange arm, an automatic tool exchange apparatus of a machine tool and the like, comprises an indexing mechanism constructed of a prime mover and a plurality of follower units. The apparatus also includes a mechanism for effecting intermittent indexing operations alternately at the plural follower units in response to a rotational drive of the prime mover. A hydraulic circuit is coupled to the prime mover for imparting such a rotational drive thereto, which is necessary for one cycle of a predetermined operational sequence. The prime mover is coupled to each of the follower units so that, with rotation of the prime mover, one of the units is rotated while the other is held fixed. During one full cycle, each of the follower units executes two indexing motions and has two pause cycles. The apparatus also includes a chuck for gripping an article which is engageable with each of the follower units for rotating the chuck and opening and closing the chuck. A first one of the follower units during the latter half of a first indexing movement thereof, closes the chuck and an arm carring the chuck and also forming part of the apparatus is raised during the first indexing movement of the other follower unit. The arm is rotated by the second indexing movement of the first follower unit. The arm is then lowered by the second indexing term of the other follower unit where upon the chuck is opened during the first half of the first indexing movement of the first follower unit.

A broaching machine broaches a multiplicity of generally flat work pieces having a projection at only one side, which are advanced in a single file with the projections extending in the same direction. In order to broach the work pieces in stacked pairs in which the peripheries of the work pieces are continuous, rather than spaced apart by confronting projections, half of the work pieces are inverted and a pair consisting of one inverted work piece and one work piece which has not been inverted are stacked together and presented to a pot broach which broaches the peripheries of both work pieces of the pair in continuous cutting strokes. The finished work pieces are advanced away from the broaching station in stacked condition and are separated into two groups, one of which consists of the bottom work pieces of the pair and the otherconsists of the top work pieces of the pair. This places all work pieces in the same orientation with respect to the lateral projection. The work pieces are then fed alternatively into a single file conveyor.
