Abstract
1371181 Lapping PAYNE PRODUCTS INTERNATIONAL Ltd 26 Oct 1972 [3 Sept 1971] 41126/71 Heading B3D A lapping machine comprises a rotary lap plate 2, conditioning rings 11 maintained on the plate by bracket arms 7 in the form of yokes, a supporting structure 5 rotatable concentrically about the press of the lap plate and providing a mounting for the bracket arms, a loading table 12 reversably movable to a location adjacent the lap plate, the loading table having a flat loading surface 25 and being provided with means 14, 21 so that its surface may be raised and lowered to a position slightly higher, and a position slightly lower than the lap plate at its adjacent location, and means for rotating the supporting structure over successive angular distances of 360 degrees/n, where n is the number of conditioning rings. The supporting structure consists of a base ring 3 which is mounted concentrically to the lap plate and has three upstanding struts 4 secured to a triangular structure 5. Columns 6 extend downwardly from the structure 5 and carry the yokes 7 which have rollers for engaging the conditioning rings. Pneumatic cylinders 8 are also carried by the structure for moving disc-shaped weights 10 into and out of engagement with workpieces located within the conditioning rings. The base ring 3 is indexable by a chain drive to bring each conditioning ring successively adjacent the loading table 12 which is movable between an inoperative position and a position adjacent the lap-plate by a ram 23, the table having slotted brackets 22 on its lower side engaged by pins 15 on parallel links 16 pivoted to the base of the machine; the slots enable the table to move horizontal during the final movement into its operative position and fingers 14 on the table to rest on the lap plate and position the table slightly below the plate to facilitate sliding of a conditioning ring with finished workpieces on to the table. As a conditioning ring with workpieces to be lapped is moved towards the lap plate, a switch is actuated so that pneumatic rams 19 rock levers 20 about pivots on the fingers 14 to move plungers 21 into engagement with the lap plate whereby the table 12 is raised slightly above the plate to facilitate movement of the conditioning ring and workpieces on to the plate. After one third of the lapping time, the procedure is repeated to change the next conditioning ring, and so on.
