The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
According to the product design characteristic and the processing request of flange, the unsuitable structure of Double Tops point of using is processed, and therefore must design the special-purpose processing tool that is suitable for the flange profile improves passing rate of processing.
Like Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5; The flange spline expansion set of the utility model comprises annular expansion set body 20; One end of expansion set body 20 is provided with the external splines 25 of the periphery that protrudes from expansion set body 20; The other end of expansion set body 20 is provided with endoporus boss 23; The inwall of expansion set body 20 is provided with inner conical surface 21; Inner conical surface 21 is diminished to other end diameter by an end at external splines 25 place gradually, also be provided with on the expansion set body 20 two end faces by expansion set body 20 have respectively extend vertically, stagger and be provided with and, be filled with the elasticity viscose glue in the said open type expansion joint (E.J.) 22,24 each other with respect to the open type expansion joint (E.J.) 22,24 that expansion set body center line 26 is uniformly distributed with.
Its operation principle is: when work, apply uniform radial load through the axle 1 that has male cone (strobilus masculinus) to expansion set body 20 and make open type expansion joint (E.J.) 22,24 expand, the cylindrical of expansion set body 20 becomes the conical surface by cylinder; With the path location of the internal spline 51 of flange 5, accurate positioning is reliable, and external splines 25 cooperates with internal spline 51; Work to stir flange 5 and rotate, do not interfere with internal spline 51, open type expansion joint (E.J.) 22,24 is uniformly distributed with respect to expansion set body center line 26; And be filled with the elasticity viscose glue, guarantee 2 homogeneous deformations of flange spline expansion set, reduce ovality; When not working, flange spline expansion set 2 can reinstatement.
Like Fig. 1 and shown in Figure 4, the end of said open type expansion joint (E.J.) 22,24 is a circular groove 220,240, avoids open type expansion joint (E.J.) 22,24 terminal stress to concentrate the service life that helps improving flange spline expansion set 2.
