Detailed description of the invention
As shown in Figure 1, planetary gear gear hobbing mandrel of the present utility model, comprises mandrel body 1, mandrel body is provided with successively lathe linkage section 2, trade union college section 3 and spacing section 4, the diameter of lathe linkage section 2 is less than the diameter of trade union college section 3, the diameter that the diameter of trade union college section 3 is less than spacing section 4.
As shown in Figure 2, three workpiece 5 to be excessively engaged in trade union college section 3 and to offset farthest away from the workpiece of lathe linkage section 2 and spacing section 4, lathe linkage section 2 is connected and fixed with the lathe collet 6 of lathe, lathe collet 63 offset farthest away from the workpiece of spacing section on one end of trade union college section 3 and trade union college section 3 and trade union college section.
As shown in Figure 3, the trade union college section 3 of mandrel body 1 is provided with locating hole near the side of lathe linkage section, is provided with steel ball 7 in locating hole, a part of spheroid of steel ball 7 from locating hole protrude and with trade union college section offset farthest away from the workpiece of lathe linkage section 2.
Shown in Fig. 2, Fig. 3, be provided with the cavity of spacing section of 4 side openings in mandrel body 1, cavity to extend in trade union college section 3 and makes locating hole and cavity connects, is provided with 30 ° of conical heads 8 in cavity.The cone head part of the front end of conical head 8 and steel ball 7 offset and conical head 8 is movable in cavity that steel ball can be made to move up and down in locating hole, the rear end of conical head 8 is provided with bolt 9, spring 10 is provided with, by exerting a force to the rear end of bolt to make the conical head displacement on front side of bolt between bolt 9 and conical head 8.The bosom of cavity is provided with the groove adapted with the cone head part of conical head, and bolt 9 is positioned at cavity completely, and the rear end of bolt 9 is provided with cone tank, drives conical head displacement by top to bolt force to make bolt.
During use, workpiece 5 to be inserted in trade union college section 3 and to offset with spacing section 4, subsequently mandrel body 1 being inserted the lathe collet 6 of gear hobbing lathe, be fixed by the axis of lathe collet 6 and spacing section of 4 pairs of workpiece; Workpiece is excessively engaged in trade union college section, and offsets farthest away from a workpiece of spacing section and the steel ball 7 of mandrel body, and steel ball 7 applies elastic force to be fixed the circumference of workpiece to this workpiece.Start gear hobbing lathe after fixing to workpiece and carry out workpiece gear hobbing.
After gear hobbing completes, mandrel body 1 is taken off from lathe collet 6, slightly firmly workpiece 5 is taken off from trade union college section 3, due to frequent use of the present utility model, repeatedly taking off workpiece can make steel ball 7 be absorbed in gradually in locating hole, exerted a force to bolt 9 by top, a part of spheroid of steel ball is ejected locating hole by conical head 8 again.Need hardly after the utility model is shaping to move bolt 9 and conical head 8, so bolt 9 is arranged in cavity completely.
