[0013] The present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings.
[0014] a kind of like figure 1 The shown end-tooth flange fork slotting positioning device includes an expanding mandrel 3 corresponding to the ear hole of the end-tooth flange fork 1 to be processed, and the expanding mandrel 3 is connected to a taper handle that matches the taper hole of the machine tool 5, a through hole is provided on the central axis of the taper shank 5 and the expansion mandrel 3, and there are several axially arranged slits 31 at the free end of the expansion mandrel 3. A pull rod 6 runs through the hole, and one end of the pull rod 6 is connected with a tapered pull head 2 matching the tapered inner hole at the end of the expansion mandrel 3, and a cylinder rod is arranged at the other end of the pull rod 6. A cylinder 9 that is relatively rotatable with the pull rod 6 .
[0015] The present invention drives th...
