Abstract
Abstract This invention deals with an apparatus for transporting workpieces between the chucks of various machining stations and for centering the workpieces relative to the chucks, having at least one spider that is movable step-by-step about a trunnion and whose arms are longitudinally adjustable relative to the trunnion, each arm having at its free end a workpiece carrier that is rotatably mounted about its own axis of rotation.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
165 words
An apparatus for transporting workpiece carriers and workpieces carried thereby between chucks of various machining stations, comprising a plurality of workpiece carriers having face-splining on one face and means for clamping the workpiece on an opposite face, and further having a peripheral groove coaxial with said face-splining. a plurality of chucks having complementary face-splining and means for axially clamping together the face-splinings of the chucks and any one of said workpiece carriers, at least one spider being step-by-step rotatable about a trunnion each spider having a plurality of telescopic radial arms comprising a fixed guide extending radially with respect to said trunnion and a means slidably secured to said guide to move in the radial direction relative thereto, each arm having a gripping appliance at its free end comprising a pair of swingable levers spring-biased toward one another and adapted to engage said peripheral groove of any one said workpiece carriers, said levers when engaged in said peripheral groove permitting rotation of the workpiece carrier.
Claim 2
Independent Claim
165 words
An apparatus for transporting workpiece carriers and workpieces carried thereby between chucks of various machining stations, comprising a plurality of workpiece carriers having face-splining on one face and means for clamping the workpiece on an opposite face, and further having a peripheral groove coaxial with said face-splining. a plurality of chucks having complementary face-splining and means for axially clamping together the face-splinings of the chucks and any one of said workpiece carriers, at least one spider being step-by-step rotatable about a trunnion each spider having a plurality of telescopic radial arms comprising a fixed guide extending radially with respect to said trunnion and a means slidably secured to said guide to move in the radial direction relative thereto, each arm having a gripping appliance at its free end comprising a pair of swingable levers spring-biased toward one another and adapted to engage said peripheral groove of any one said workpiece carriers, said levers when engaged in said peripheral groove permitting rotation of the workpiece carrier.
Claim 3
Dependent Claim
27 words
The apparatus as set forth in claim 1 in which each oF said swingable levers has two rollers rotatably journaled thereon for engaging in said peripheral groove.
Claim 4
Dependent Claim
41 words
The apparatus as set forth in claim 2 in which one of said rollers on each of said levers is journaled on a pin pivotally supporting the respective lever, said pin being fixed to the outer end of the respective arm.
Claim 5
Dependent Claim
88 words
The apparatus as set forth in claim 1 in which each of said telescopic arms has a pinion rotatably mounted near the outer end of said arm, said pinion being connected to a drive mechanism disposed on the arm. each of said workpiece carriers having a gear ring fixedly arranged thereon which is concentric with the face-splining and the peripheral groove of said workpiece carrier, said pinion meshing with said gear ring when the levers of said arm are engaged in the peripheral groove of the workpiece carrier.
Claim 6
Dependent Claim
68 words
The apparatus as claimed in claim 1 in which said spider comprises a bearing housing for each arm, said guide means of said arm being mounted in said bearing housing so as to be rotatable about is longitudinal axis and said guide means being fixedly connected to a pinion in the bearing housing, said pinion meshing with means for causing said pinion and said guide means to rotate.
Claim 7
Dependent Claim
37 words
The apparatus as set forth in claim 5 in which said bearing housing of each arm is guided on a guide post extending parallel to said trunnion with means for moving said bearing along said guide post.
Claim 8
Dependent Claim
72 words
The apparatus as set forth in claim 1 in which each workpiece carrier has a support ring concentrically disposed with the face-splines of the workpiece carrier and each chuck has a tie rod slidable along the axis of the face-splines of the chuck, said tie rod having at its one end swingably disposed hooked levers which may be brought into engagement with the support ring from within to hold the face-splines together.
Claim 9
Dependent Claim
38 words
The apparatus as set forth in claim 1 comprising radially within the face-splines of at least one of said chucks a hollow nozzle ring disposed with outwardly directed nozzles for dispensing a flushing agent which cleans the face-splines.
