Novel automatic positioning device

The utility model discloses a novel automatic positioning device is proposed, guaranteeing that wheel hub reduces the requirement of operating personnel technical ability, reduction in the number of rejects, reduction repair rate on milling the processingquality basis, reduces the potential safety hazard, reduces operating personnel intensity of labour. The utility model provides a: according to blank draft die angle development toper nylon locating piece, use the screw thread to link with scalable dress ware, the expansion bend is directly flexible through the spring with the cutter arbor, and the expansion bend passes through the bolt to be linked with the cutter arbor, installation of cutter arbor reuse sword cup and lathe, the angle of toper nylon piece the same with blank window angle, through casting wheel hub window location and the control of lathe numerical control program, realize the automatic positioning function. 本实用新型的目的在于提出种新型自动定位装置，在保证轮毂铣加工质量基础上降低操作人员技能要求、降低废品率、降低返修率、降低安全隐患、降低操作人员劳动强度。本实用新型的技术
