Abstract

944,663. Grinding. REGIE NATIONALE DES USINES RENAULT. March 21, 1960 [April 9, 1959], No. 9944/60. Heading B3D. [Also in Division B8] A feed device, associated with an automatic machine tool for delivering workpieces to be machined to the tool, is arranged to deliver one workpiece at each operating cycle of the tool and includes means operable to release a workpiece held in the feed device so that the workpiece so released can be fed by the device to the tool, and the tool has means for ejecting each workpiece from the tool after machining of the workpiece such that the workpiece travels along a predetermined path to operate the first-mentioned means whereby the feed device is controlled during operation by the ejection of each workpiece just machined. A machine for grinding the shanks of engine valves 3 comprises grinding wheels 1, 2. These are moved apart and a valve introduced therebetween, its shank resting on a guide 4 and its head on a resilient pad 4<SP>1</SP>. The wheels are then brought together to grind the shank. The wheels are then moved apart and the ground valve is ejected by a pusher 5. Valves are placed at 7 into a feed device comprising spaced plates 9 secured by bolts 12 to a bracket 13 attached to the grinding- machine frame. The valve heads rest on the inclined upper edges 6 of the plates with the shanks received between the plates. A retaining rail 10 is provided. The valves are released to the machine one at a time by oppositely reciprocating fingers 14, 15 pivotally connected to the ends of a lever 20 on a shaft 21 rotated in one direction by a torsion spring 26 and in the other direction by an electromagnet 22. This is controlled by a switch 40 actuated by a pivoted rod 37 in the path of an ejected workpiece. A finger 30 is pivoted at 31 and its upper portion is forked to engage a groove in a stud 33 carried by the pivot-pin of the finger 15. The lower portion of the finger 30 displaceable in an aperture 34 of the adjacent plate 9 has a stop portion 35. The downward travel of the valve between the grinding wheels is controlled by an elastic guide member 36 on the end of the retaining rail 10. A feeler 42 in the path of worpieces in the feed device operates a switch 41 which interrupts the automatic cycle of the machine if there are no workpieces in the feed device.
