Abstract
1338988 Grinding; workpiece transferring CARMET CO 17 Feb 1972 [18 Feb 1971] 7484/72 Headings B3D and B3B Apparatus for loading and unloading workpieces 20 on to and from e.g. a grinding machine or lathe comprises a reciprocable chuck member 10 having a work-locating groove 14, means 22 for feeding a workpiece 20 into the groove 14, suction means for holding the workpiece 20 in the groove 14, and means 86 for advancing the chuck member 10 to a position at which the workpiece 20 may be clamped by clamping means 42, 44, whereupon the suction means 16 is deactivated, and the chuck member 10 retracted. On actuating pneumatic means 26, the leading workpieces 20 of a series on a magazine block 18 is advanced into engagement with a stop 30, suction then being applied through openings 16, while a finger 32 is pivoted into engagement with the workpiece 20 by pressure acting on a piston 108 against the force of a return spring 110. The member 10 is then advanced by fluid pressure means 86 acting through a bracket 92 and adjustable screw connection 98, 100, a pin 102 engaging a fixed notch 130 to define the fully advanced position. One clamping spindle 42 is then advanced relative to the other 44, whereupon the finger 32 is retracted and the suction cut off, the workpiece 20 then being ground by a grinding wheel 62. The member 10 is then readvanced to collect the workpiece 20, release of the finger 32 and de-activation of the suction means causing the workpiece 20 to fall out for collection after withdrawal.
