For reaching above object, the technical scheme that the present invention takes is:
A kind of split type cycloid disc numerical control milling positioning fixture, comprise mold, inner expension cap, outer expansion set and bolt, the center of described mold is provided with annular groove and the cylinder boss of coaxial line, on the outer circumference surface of described cylinder boss, coaxial sleeve is connected to inner expension cap, the inner peripheral surface of described annular groove is coaxially connected with outer expansion set, the outer of described mold is provided with bolt hole more than two, is provided with the bolt be connected with the T stage of CNC milling machine in described bolt hole.
Further, be provided with the uniform interior cylinder pin hole of a circle and bottom described annular groove and enclose uniform outside cylinder pin-and-hole, be provided with in described interior cylinder pin hole in interior straight pin, outside cylinder pin-and-hole and be provided with cylindrical pin.
Further, in described annular groove, be provided with circular interior parallels and circular outer parallels, described interior parallels be provided with corresponding with outside cylinder pin-and-hole in parallels pin-and-hole, described outer parallels is provided with the outer parallels pin-and-hole corresponding with outside cylinder pin-and-hole.
Again further, described interior parallels is coaxially arranged with outer parallels and thickness is identical.
After taking above technical scheme, beneficial effect of the present invention is:
(1) positioner structure is simple, uses common turnery processing can arrive inner convex platform, annular groove axiality and annular groove bearing-surface planarity requirements.
(2) utilize expansion set centering good, the feature that tension force is large, use inner sleeve and outer expansion set to coordinate with cylinder boss and annular groove respectively and divide body disc to locate medial and lateral, locate mode is simple, accurate, reliable.
(3) utilize straight pin to coordinate mold cylinder pin hole to behind inside and outside point of body disc circumference location, same numerical control program milling medial and lateral can be used to divide the cycloid flank of tooth of body disc, and locate mode is simple and reliable.During reductor assembling, inside and outside point of body disc is also located based on the pin-and-hole of same position, is easy to aligning of the medial and lateral flank profil of cycloid groove.
(4) Z2 type expansion set easy accessibility, be convenient to batch production, and can not destroy the inside and outside boss surface of mold, mold can prolonged and repeatedly use.
