Precise positioning and clamping device for stepped thin-wall barrel

Abstract

The invention discloses a precise positioning and clamping device for a stepped thin-wall barrel, belongs to the technical field of technological equipment and is mainly suitable for precisely positioning and clamping the thin-wall barrel when performing machine finishing on stepped thin-wall barrel parts. The main technical characteristics of the device is that the device comprises a main taper shaft 1, a fixed cone 2, an anti-rotation pin 3, a stop screw 4, a two-way step expansion spring 5, a spring 6, a movable cone 7, a guide pin 8, a waist-shaped hole 9, a fastening nut 10 and a turning handle 11, wherein the outer cylindrical surface of the two-way step expansion spring 5 is provided with steps according to the step size and the step position of the stepped thin-wall barrel to be processed; a guide groove at one large-diameter end of the two-way step expansion spring 5 is aligned with and inserted into the anti-rotation pin 3; and the left conical surface of the two-way step expansion spring 5 is jointed with the conical surface of the fixed cone 2. The device can meet the high-accuracy processing requirements on uniform wall thickness difference and high coaxiality between inner and outer circles on a variable-diameter cylindrical thin-wall member, and has the characteristics of convenient installation and operation, reliable use and the like.
