Abstract
A drilling machine capable of rapid change over for drilling different parts, and which has stations for simultaneously, or sequentially, drilling holes in a particular part. The unit includes means for positively positioning the part, and gripping the part, and rotating or indexing the part to different rotational positions for the drilling operation. Control means are utilized for positively and precisely positioning the part for the various drilling operations.
Claims5
An indexing control for controlling operations on an indexed part movable about an axis including a base, means to rotatably mount said part on said base for rotary indexing motion about a preselected axis, an indexing control, synchronizing drive means driving said indexing control and said means rotatably mounting said part, means to initiate said drive means at preselected times, control means controlled by said indexing control separate from said means to initiate said drive means, said indexing control comprising a rotatable member having cam support means positioned at a plurality of locations about the axis thereof for removably mounting cam means, cam means mounted on at least one of said cam support means on said rotatable member, said control means including an actuator positioned with respect to said base at a location so cam means positioned on said rotatable member engages the actuator at a desired rotational position as the rotatable member is rotating to provide a signal indicating a rotational position of said means rotatably mounting said part which is correlated precisely with the rotational position of said part through said synchronizing drive means.
