Abstract

1335649 Limit switches; actuation of switches BORG-WARNER CORP 29 March 1972 [4 May 1971] 14733/72 Heading H1N A switch assembly for providing control signals as a function of angular motion (to provide accurate location of a motor-driven carriage of a machine tool, for example) comprises a lead screw 28 having a portion 18 to receive rotational drive and a portion which is both threaded, at 30, and has at least one longitudinal slot 31; an indexing nut 32 received on threads 30 and means to prevent its rotation as it is displaced longitudinally by rotation of lead screw 28; a cam body 35 having at least one interior tang 37 extending into a slot 31 and at least one exterior lobe 36; means for effecting longitudinal displacement of the cam body 35 as a function of the displacement of the nut 32, concomitantly with the angular displacement of the cam body 32 as the screw 28 is rotated; and a plurality of switches 43 adjacent the path of travel of the lobe 36 for actuation thereby to provide the said control signals. As shown the nut 32 is restrained from rotation by a pin 33 thereon engaged in a slot 34 in the interior of housing 25. Cam body 35 is carried on nut 32 by a bearing 38 and has four tangs 37 respectively engaged in four slots 31. The switches 43 are mounted on a pair of plates 46 (only one being shown in Fig. 2) by means of screws 47 and springs 48 which permit adjustment of their positions for accurate
